Fiona wants to use the scientific method to answer the question "Do oxygen levels in the air of photosynthesis?" She reads about photosynthesis in her biology book and is ready to carry the next step. should she do next? O perform an experiment design a procedure make observations a hypothesis
Answer: hypothesis, prediction, design experiment, carry out experiment, etc
Explanation:If the question is supposed to be, is there a connection between atmospheric oxygen level and photosynthesis, then the next step would be to frame the hypothesis, which could be, for example,
“photosynthesis requires oxygen”, and a prediction such as,,
in a closed system, photosynthesis will reduce the oxygen level, or even photosynthesis does not proceed without oxygen.
and a format to test the hypothesis (design an experiment)
perform the experiment
collect data
analyse data
(of course, in this case, the data will support the null hypothesis).
Answer:
The correct answer is D!:)

What are the differences you can see when you compare the nucleons of a dividing cell with that of a non dividing cell
Answer:
Chromosomes will be seen in the nucleus of dividing cells (during mitotic and meiotic cell divisions) because they are visible when a cell is dividing as oppose to non dividing cells. Also, all processes of cell division from prophase, metaphase, anaphase to telophase will be seen :)

Consider an organism that has a dominant phenotype, is it possible to determine its genotype? explain your answer
Answer:
Yes, it is possible via testcrossing
Explanation:
The law of dominance has made it possible that a phenotype may be expressed without knowing the actual genotype (allele combination). This occurs when an allele is dominant over another allele (recessive), hence, the dominant phenotype can either be in a heterozygous or purebred state.
However, a way to discover the genotype of an organism that is portraying dominant phenotype is TEST CROSS. Test cross is the crossing of the unknown genotype with a recessive condition (will contain same recessive alleles).
After crossing, the offsprings will be used to determine whether the parent with unknown genotype is heterozygous or not.
- If the offsprings all exhibit the dominant phenotype, the unknown genotype contains the same dominant alleles e.g DD.
- If 50% of the offsprings exhibit a recessive phenotype, the unknown genotype is heterozygous e.g Dd.

What is the amplitude?
A. the distance from the center of the wave to the crest or the trough.
B. The distance between the two crests
C. The highest point in the wave
D. The lowest point in the wave
The distance from the center of the wave to the crest or the trough, hence option A is correct.
What is amplitude?It alludes to the greatest departure from equilibrium that an item in periodic motion may exhibit. As an illustration, consider how a pendulum moves through its equilibrium point (straight down) and then moves outward to its maximum extent.
Measure the largest displacement of a point in the wave's medium from its resting position to determine its wavelength. Measure the length of the wave's cycle, generally from peak to crest or trough to trough, to determine its amplitude.
Think about how a pendulum travels through its equilibrium point (straight down) and then goes outward to its farthest point as an illustration.
Therefore, the distance from the center of the wave to the crest or the trough, hence option A is correct.

Answer:

postsynaptic neuron
Explanation:
That's the mechanism of action potential generation. Neurotransmitter receptors are connected to sodium channels. When those sodium channels open the cell becomes depolarized(the charges reverse), that means the inside of the cell becomes more positive while the outside becomes negative

Change the following sequence (GGAUUC) to show:
a. Substitution
b. Insertion
c. Deletion
DONT CHOOSE A< B< C
I need each of those to have an answer. So if you dont know how to do it , dont say anyhting. I will give brainlist
Answer:
Given the sequence of bases of the RNA GGAUUC, the possible mutations would be:
a. Substitution: GGAUUC → GGAAUC
b. Insertion: GGAUUC → GGACCUUC
c. Deletion: GGAUUC → GG_UC
Explanation:
The fragment observed is recognized as RNA, due to the presence of uracil (U). The mutations observed in this fragment are derived from a mutated DNA molecule, which was transcribed into mRNA
Substitution is a molecular mutation that occurs when one nitrogenous base is changed to another in the DNA sequence. GGAUUC → GGAAUC Mutated DNA: CCTTAGInsertion occurs when entire bases or segments are added to the original genetic material, resulting in a longer molecule. GGAUUC → GGACCUUC Mutated DNA: CCTGGAAGDeletion is a type of mutation where genetic material is lost, which can be nitrogenous bases or segments of the molecule. GGAUUC → GG_UC Mutated DNA: CC_AGEach of these mutations can have an effect on protein synthesis, affecting the structure or function of the final protein.

How do frogs and toads, as well as salamanders, typically protect themselves from predators?
by injecting venom into the predator using teeth
by crawling or hopping to a safe place
by squeezing the predator to suffocate it
O by rolling over and pretending to be dead
Answer:
by crawling or hopping to a safe place
Explanation:
Most Amphibians like frogs, road, salamander protect themselves from predator by hopping and crawling to a safe place because they have the ability to puff out and look bigger in the sight of the predator. They can also remain underneath in water quietly for a long time. For example frog secrete moisture which sometimes it is irritating to the predators and serve as a defensive mechanism.

The mosquitos have different traits because they have different proteins for body size feature in their cells. Differences in the structure of protein molecules affect how they interact with other protein molecules. A gene version provides instructions for making a specific protein, so mosquitos with different combinations of gene versions will have different proteins in their cells that result in small, medium, or large body sizes. Each parent randomly passes on one of its two copies of a gene for a feature, which is why each mosquito offspring can have a different combination of gene versions even though they have the same parents.
Answer:
The mosquitos have distinctive characteristics since they have diverse proteins for body measure highlight in their cells. Contrasts within the structure of protein atoms influence how they associated with other protein atoms. A quality form gives enlightening for making a particular protein, so mosquitos with distinctive combinations of quality adaptations will have distinctive proteins in their cells that result in little, medium, or huge body sizes. Each parent haphazardly passes on one of its two duplicates of quality for a include, which is why each mosquito sibling can have a diverse combination of quality forms indeed in spite of the fact that they have the same guardians.

What impact could artificially raising the carrying capacity have on the deer
population long term?
Answer:
Deer population increases.
Explanation:
Deer population increases if increasing occur in carrying capacity of an ecosystem by artificial means because more food, water, shelter and other resources are available to the deer due to increasing carrying capacity of an ecosystem. If food, water and shelter are available in large amount to the deer so they reproduce rapidly and increase occur in their population.
Smokers, alcohol abusers, overweight and obesity men are more
likely to have sperm which are?
Answer:
fewer in number.
Explanation:
A low sperm count also known as oligospermia can be defined as a medical condition which typically involves a man (adult male) having fewer than 15 million sperm per millilitre of semen.
Basically, low sperm count (oligospermia) is usually caused in men due to health and lifestyle factors such as smoking, alcohol or drug abuse, obesity, genetics, sexually transmitted infections (STIs), age etc.
Hence, smokers, alcohol abusers, overweight and obesity men are more likely to have sperm which are fewer in number i.e fewer than 15 million sperm per millilitre of semen.
Generally, a healthy or normal sperm motility ranges from over 20 million to 200 million sperm per millilitre of semen.
