Answer: The options are not given, here are the options.
A. One species is much better competitor than the other.
B. Periodic disturbances allow for coexistence.
C. Two species tended to use different resources.
D. The two species experienced interference competition and not exploitative competition.
The correct option C.
Two species tended to use different resources.
Explanation:
From Gause experiments on competing paramecium pairs, He found out that most times both species persisted and sometimes only one did because the two species uses different resources.
Organisms normally compete for limited resources in order to survive and one intend to compete well while other suffer. Both in the case of competing paramecium pairs, the pair use different resources which make the to persist and survive well. Once the resource of one finishes, the other one will persist because it is still surviving on its available resources.

Which macromolecule is made up of nucleic acids ?
A. Sucrose
B. RNA
C. Fatty Acids
D. Protein
Answer:
Ribonucleic acid (RNA)
Explanation:
DNA (deoxyribonucleic corrosive) is the most widely recognized type of hereditary material found in numerous living beings.
Nucleic acids connect the two strands of the DNA double helix together.
RNA (ribonucleic corrosive) is additionally found as genetic material (and not DNA) in certain creatures like infections.
Infections could have ssRNA (single-stranded RNA) or dsRNA (double-stranded RNA) as their hereditary material.
However, RNA is generally single-stranded, in contrast to DNA, which is double-stranded consistently.
Another type of RNA is messenger RNA (mRNA), ribosomal RNA (rRNA), transfer RNA (tRNA), etc
1. What were the first living things on Earth?
Answer:
prokaryotes
Explanation:
Gonorrhea is a sexually transmitted infection (STI) caused by the diplococcus Neisseria gonorrhoeae, commonly called gonococcus (GC). This organism developed resistance to penicillin and tetracycline in the 1980s, after which fluoroquinolones were the recommended drugs for treating GC. Subsequent resistance to the fluoroquinolones has led to the current recommended treatment of injected ceftriaxone in combination with oral azithromycin. Although this approach continues to be effective, recent data from the CDC indicates that resistance to azithromycin is emerging.Fluoroquinolones act by inhibiting DNA gyrase, an enzyme involved in DNA replication. Resistance to this antibiotic is most commonly by a. due to a mutation in the gene that encodes RNA polymerase, an example of adaptive resistance. b. a change in the DNA gyrase target, an example of acquired resistance increased efflux of the drug from the target cell, an example of innate resistance. c. a change in the DNA gyrase target, an example of innate resistance. d. enzymatic modification of the ribosomal target, an example of innate resistance.
Answer:
The correct answer is option b, that is, a modification in the target of DNA gyrase, is an illustration of acquired resistance.
Explanation:
The activity of DNA gyrase gets inhibit by fluoroquinolones. The enzyme that combines with the DNA and prevents its supercoiling at the time of replication is termed as DNA gyrase. It is a heterotetramer, which is formed of two subunits of GyrA and two subunits of GyrB. Due to the mutation in gene gyrA, the development of resistance takes place in N. gonorrhea against fluoroquinolones.
Post mutation, gyrA exhibits lesser binding capacity with the fluoroquinolones, and thus, the development of resistance takes place within the bacteria against the fluoroquinolones. The phenomenon of the development of resistance taking place in any microbe against the specific antimicrobial agent for whom it was vulnerable before is termed as acquired resistance, thus, the given case is an illustration of acquired resistance.

O (4) CUC-UUA-UUU-GUU-CGA-UAU
Answer:
(2) UAU-CGA-GGA-GUU-GCG-CUC
Explanation:
The mRNA is produced by the process of transcription which transcribes the DNA to mRNA which can be recognised and read by the ribosomes.
The ribosomal subunits get attached to the mRNA which scans or read the mRNA in the form of codons or triplets of nucleotides. These codons code for particular amino acid and about 64 codons code for 21 amino acids.
In the given question, the sequence of the amino acids in the peptide has been provided based on which the sequence of codons can be easily decoded.
For the provided peptide, the sequence of amino acid will be Option-2 which is UAU-CGA-GGA-GUU-GCG-CUC as this sequence of codons has the codons arranged according to the sequence of the amino acid.
Thus, Option-2 is the correct answer.
UAU-CGA-GGA-GUU-GCG-CUC is the sequence code that encodes the mRNA TYR-ARG-GLY-VAL-ALA-LEU
A codon table is usually employed in translating the genetic code into amino acid sequencesmRNA plays a major role in protein synthesis which originate from the joining together of individual amino acids in the ribosomes.
These amino acids are encoded by three letters that form a codon. There are 64 different codons in the genetic code encoding for the entire 20 amino acids.
The amino acid chain is thus decoded as:

Why are detritivores, decomposers and omnivores not assigned trophic levels
Answer:
The reason is because detritivores and decomposers and omnivores are multilevel food chain consumers in an ecosystem making them not qualified to be assigned to a given trophic level
Explanation:
An organism is placed in a trophic level based the level it is from where the food chain starts with the start of the food chain having a level of 1 for the food producers such including plants and algae
Level 2 organisms are called primary consumers and consists of organism that eat only plants known as herbivores such as cattle
Level 3 organisms are called secondary consumers and consists of animal eating organism known as carnivores such as foxes etc.
Level 4 organisms are called tertiary consumers
Level 5 organisms are the a p e x p r e d a t o r s
Detritivores and decomposers such as bacteria, earthworm flies fungi consume the wastes produced at all trophic levels, therefore they cannot be assigned to a particular trophic level
Similarly, omnivores consumes both plants at level 2 and animals at level 3 making it ambiguous to assign them to one particular trophic level.
There are two different alleles for flower color, P and p. The image shows a purple sweet pea that is labeled with its two alleles for petal color. A purple sweet pea is labeled Upper P Upper P. Which is the genotype of the sweet pea?
Answer:
There is no diagram but the question can be answered using the description. The options to this question are:
Which is the genotype of the sweet pea?
A.heterozygous dominant
B.heterozygous recessive
C.homozygous dominant
D.homozygous recessive
The answer is C (homozygous dominant)
Explanation:
According to the question, a flower colour gene in a pea plant possesses two different alleles, P and p. Lettercase is used to illustrate that allele P (upper case) is dominant over allele p (lowercase) i.e P will be expressed over p in the flower colour gene.
According to the question, the pea plant exhibits a purple flower colour and is labelled as PP. This genotype is said to be homozygous because the same alleles (P) make up the plant's genotype. Since the allele P coding for purple coloration is dominant, the purple sweet pea is said to be HOMOZYGOUS dominant i.e. possess the same dominant alleles for that gene.

Group of answer choices A.the complete mineral composition of the sandstone B.the direction of the wind at the time it was deposited C.the tectonic history of the deposit D.the origin of the sand in the deposit
Answer:
B. the direction of the wind at the time it was deposited
Explanation:
Cross beds refers to those rock beds which are formed due to the deposition of bed forms such as dunes. These cross beds are the group of inclined layer which is formed due to the flowing of water or wind. These rock beds represents the movement or direction of wind and water at the time of deposition and as a result cross beds are formed. So we can say that cross beds were formed due to the direction of wind.

Is it important before a blood transfusion to know blood types? Why? What are the benefits or consequences?
Answer:
It is extremely important to know all types of blood because if you donate the wrong type of blood to another person, he/she will get sick.
Explanation:
Hemolytic transfusion reactions can cause the most serious problems, but these are rare. These reactions can occur when your ABO or Rh blood type and that of the transfused blood do not match. If this happens, your immune system attacks the transfused red blood cells. This can be extremely life-threatening.
Why would a drop in blood pH have an undesirable effect on the proximal histidine's function?a. A drop in pH would make deprotonation more likely, and a deprotonated proximal histidine would be able to hydrogen bond to O2 to stabilize its binding to the heme.b. A drop in pH would make protonation more likely, and a protonated proximal histidine would not be able to donate its electron density to the iron atom.c. A drop in pH would make protonation more likely, and a protonated proximal histidine would not be able to hydrogen bond to O2 to stabilize its binding to the heme due to its positive charge.
Answer:
c. A drop in pH would make protonation more likely, and a protonated proximal histidine would not be able to hydrogen bond to O2 to stabilize its binding to the heme due to its positive charge.
Explanation:
Protonation refers to the addition of proton or H+ to the atom or molecule. If the pH of blood drop means acidic so it causes adverse effect on the function of proximal histidine because the proximal histidine gain proton and become cation. Due to this proton, proximal histidine is unable to make hydrogen bond between heme and oxygen and the blood is unable to transport more oxygen with hemoglobin from the lungs.
The graph below compares the rates of reaction of a burning candle and an exploding firework.
Comparing Chemical Reactions
A graph has time on the horizontal axis and concentration of reactants on the vertical axis. For an exploding firework, the concentration starts high, increases slightly and then decreases rapidly. For a burning candle the concentration starts high, increases more than the firework, and then decreases rapidly. The concentration for the burning candle is higher than the firework at all timepoints.
What can you conclude from the graph?
The reaction that causes a firework to explode requires less energy to start, and occurs more rapidly than the reaction that causes a candle to burn.
The reaction that causes a firework to explode requires less energy to start, and occurs less rapidly than the reaction that causes a candle to burn.
The reaction that causes a firework to explode requires more energy to start, and occurs less rapidly than the reaction that causes a candle to burn.
The reaction that causes a firework to explode requires more energy to start, and occurs more rapidly than the reaction that causes a candle to burn.
Answer:
The reaction that causes a firework to explode requires less energy to start, and occurs more rapidly than the reaction that causes a candle to burn.
Explanation:
The speed of a chemical reaction and the amount of energy required for this reaction is directly linked to the concentration of reagents present in the system. With that, we can say that the higher the concentration of reagents, the faster the chemical reaction will be due to the greater probability of collision between its molecules.
Although the reaction that causes a candle to burn has more reactants than the reaction that causes the fireworks to explode, the latter requires less energy to start. This makes the molecules of the reagents stir faster and collide more efficiently, making the reaction happen much faster.
In summary, the reaction that causes a firework to explode requires less energy to start and occurs more quickly than the reaction that causes a candle to burn.
The reaction that causes a firework to explode requires more energy to start, and occurs more rapidly than the reaction that causes a candle to burn.
The rate of reaction refers to the ease with which reactants are converted to products. The higher the rate of reaction, the faster reactants are converted into products.
The activation energy is the energy required for reactants to be converted into products. It is an energy barrier that separates reactants and products.
From the description of the graphs, we are told that the reaction that causes the explosion of firework starts at high concentration, initially increases slightly then decreases rapidly. The fact that it initially increased slightly before decreasing rapidly implies that the high energy required for the reaction to start is high.
On the other hand, the reaction for the candle to burn starts at high concentration, increases more than the firework, and then decreases rapidly because the reaction requires a lesser energy to commence than the reaction for the burning of candle.

Female honey bees are diploid and male honey bees are haploid. The haploid males produce sperm and can successfully mate with diploid females. Fertilized eggs develop into females and unfertilized eggs develop into males. How does the process of sperm production in male honey bees differ from sperm production in other animals?
a. Male honey bees use meiosis I only, whereas other animals use both phases of meiosis.
b. Male honey bees use meiosis, whereas other animals use mitosis.
c. Male honey bees use mitosis, whereas other animals use meiosis.
d. Male honey bees can use mitosis or meiosis, whereas other animals can only use meiosis.
Answer:
The correct answer is option C.
Explanation:
In most of the male animals the production of sperms takes place through the process of meiosis. Meiosis occurs only in 2n or diploid cells. Thus the most of the animals produce sperm due to their diploid nature.
In male bees the sperm production is different than other animals as it is haploid cell and haploid cells produce sperms through mitosis. In haploid cells mitosis helps in produce more sperms.
Thus, the correct answer is option C.
