Explanation:
In carbon cycle, carbon is just being recycled from one thing to other. For example, here we can see that green plants are part of carbon cycle because they go through photosynthesis, a process through with plants take in Carbon dioxide. The carbon is then used to make molecules such as carbohydrates and proteins, and are part of structural support to plant cells as well. Now when this organism (the organism could be an animal or plant) dies, the bacteria decomposes the organic matter (the dead body) and through respiration the carbon dioxide is released back into the environment.
Another way carbon recycles is that animals, plants, and microorganisms all respire (breathe out) CO2 thus carbon dioxide is added to the environment.
Answer:
Hi.. Ok lets start with animals.....Animals give out carbon dioxide during the breathing process and obtain oxygen.The carbon dioxide given out by the animals is obtained by green plants which use it on addition to chlorophyll water and light energy to make their own food.When animals die they decompose to form micro organisms...The micro organisms add nutrients to the soil thus promoting the growth of plants.I think it is the foodchain
Which organelles are found only in plant cells and not in animal cells? cell membrane, vacuole cell wall, chloroplasts cell wall, vacuole cell membrane, chloroplasts
Answer:
Cell wall and Chloroplasts
Explanation:
I just studied hope its correct (～￣▽￣)～
Answer:
Cell wall and chloroplast
Explanation:
Plant cells are the fundamental building blocks of plants and they are eukaryotic because of the membrane bound organelles and nucleus also found in Animal cells.
Plant cells organelles are chloroplast and cellwall which is not found in animals.
Chloroplast is an organelle which contain the green pigment use for photosynthesis.
Cell wall is an organelle found in plant cell which contain cellulose, hemicellulose, liginin, pectin , soluble protein and microfibrils. It provide strength and protect the plant against mechanical or osmotic stress.
This problem leads you through the derivation of a corrected equation for RF in yeast tetrad analysis that takes into account double crossover (DCO) meioses. A yeast strain that cannot grow in the absence of the amino acid histidine (his−) is mated with a yeast strain that cannot grow in the absence of the amino acid lysine (lys−). Among the 400 unordered tetrads resulting from this mating, 233 were PD, 11 were NPD, and 156 were T.
a. What types of spores are in the PD, NPD, and T tetrads?
b. Are the his and lys genes linked? How do you know?
c. Using the simple equation RF = 100 × [NPD +(1/2)T]/total tetrads, calculate the distance in mapunits between the his and lys genes.
d. If you think about all the kinds of meiotic eventsthat could occur (refer to Fig. 5.24), you can see that the calculation you did in part (c) may substantially underestimate RF. What kinds of meioses (NCO, SCO, or DCO) generated each of the tetrad types in this cross?
e. What incorrect assumptions does the simple RFequation you used in part (c) make about themeiotic events producing each type of tetrad? Whencould these assumptions nevertheless be correct?
f. Use your answers to part (d) to determine thenumber of NCO, SCO, and DCO meioses thatgenerated the 400 tetrads.
g. Use your answers to part (f) to write a generalequation that relates the number of DCO meiosesto the number of the various tetrad types. Thenwrite another general equation that computes thenumber of SCO meioses as a function of the number of the various tetrad types.
h. Based on your answer to part (f), calculate theaverage number of crossovers per meiosis (m)between his and lys.
i. Use your answer to (h) to write an equation for min terms of NCO, SCO, and DCO meioses.
j. What is the relationship between RF and m?
k. Use your answer to part (j) to write a corrected equation for RF in terms of SCO, DCO, and NCO meioses. l. Using your answer to part (g), rewrite the corrected RF equation from part (k) in terms of the numbersof the various tetrad types.
m. The equation you just wrote in part (l) is a corrected equation for RF that takes into account doublecrossovers that would otherwise have been missed. Use this improved formula to calculate a moreaccurate distance between the his and lys genes than the one you calculated in part (c).

The Serengeti region of Africa contains a population of cheetahs and a population of lions. Studies have shown that the cheetah population has very low genetic diversity, while the genetic diversity of the lion population is quite high. The cheetah population is also much smaller than the lion population. Both populations are vulnerable to infection with a particular virus that can be fatal in both species. What is the most likely outcome if both populations are infected with this virus?
A.
The cheetah population is more likely to survive because there are fewer individuals for the virus to attack.
B.
The lion population is more likely to survive because larger populations are immune to viruses.
C.
The cheetah population is more likely to survive because lower genetic diversity increases immunity to viruses.
D.
The lion population is more likely to survive because it is more likely to have individuals with traits to combat the virus.
Answer:
D. The lion population is more likely to survive because it is more likely to have individuals with traits to combat the virus.
Explanation:
Since lions have greater genetic diversity it is likely that there's one or two lions that have a trait to resist or kill the virus thus won't be infected, whereas, since cheetah's have low genetic diversity and low population size it is likely that they have little to no chance to surviving this virus attack since the genetic makeup is similar among the members of cheetah species.

What is the genotype of the male circled in pink?
Answer:XaY
Explanation
XAY is the genotype of the male circled in pink.
What is the genotype?An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual carries in a specific gene or genetic region are also referred to as the genotype.
The term “genotype” broadly refers to an organism's genetic make-up; in other words, it characterises an organism's whole gene pool. The phrase can also be used to describe the alleles, or different forms of a gene, that an organism carries in a more specific meaning.
The genotype XAY for a male denotes the manifestation of an X-linked dominant characteristic. It is an X-linked dominant illness called fragile X syndrome. If their father has the condition, the sickness will afflict the girls, but not the males.
Therefore, The pink circled male's genotype is XAY.

What is the end product of the process of respiration? *
A. glucose and oxygen
B. water and carbon dioxide
Answer:
B. carbon dioxide and water
Explanation:
Respiration is a process that animals and plants undergo to create energy to grow, move and sustain life.
The equation for cellular respiration is:
glucose + oxygen —> ATP + carbon dioxide + water
The organisms use glucose from food and oxygen to create ATP (useable energy), carbon dioxide and water.
Therefore, the answer is B. Carbon dioxide and water. Glucose and oxygen are not the end results, they are used to make the end results.
Answer:
B. water and carbon dioxide

A student observed a dying plant in the corner of their science classroom. They learned the process of Photosynthesis and Cellular Respiration already in class. The students were trying to remember the correct chemical equation for the process. In order for the plant to be successfully creating its own food which chemical equation did the student write correctly?
Answer:
The general chemical equation for photosynthesis is
6CO2 +6 H20 → C6H1206 + 602,
Where CO2 is carbon dioxide, H20 is water, C6H12O6 is glucose, and O2 as oxygen a byproduct.
the process begins with the splitting of water molecules-Photolysis.
2H20 +2 NADP + 8 Photons → NADPH + 2H+2 O. Photons is sunlight that splits the water molecules.
Cellular respiration is the reverse of the process which is the
C6H1206 +6 O2 → 6H20 +6 CO2 +ATPs.
ATPs is the chief product, while C02 is the byproduct.

Explain the effect of temperature and pH on enzyme action.
Needs to be done ASAP.
Answer:
enzymes loose their form in both unsuitable ph and temprature.
Explanation:
at very high tempratures enzyme molecules denatures due to high speed movements, at low tempratures enzymes works too slow to be useful enough.
low ph solotions contain lot of H+ and high ph solutions have few H+ , and the number of these H+ ions have polar effects on enzymes. some Enzymes like pepsin works perfect in acidic environment ( ph=2) while others might work at high ph or average ph( like Trypsin works well at ph=7).

How does transferring energy into a container of magnetic marbles affect the speed by shaking the container gently?
By the transfer of energy into a container of magnetic marbles the speed changes because of kinetic energy produced by the shaking of container gently. This will lead to phase changes.
What is kinetic energy?All the phase changes in a system are accompanied by the change in the energy of a system. These include transfer of kinetic energy to a system. Changes from a more-ordered state to a less-ordered state are endothermic reactions. Changes from a less-ordered state to a more-ordered state are always exothermic reactions.
A phase change in a system takes place when a matter changes from one state to another state. These changes occur when sufficient amount of energy is supplied to the system or lost from the system. Phase changes also occur when the pressure on the system is changed.

O 75 percent
O 100 percent
Answer:
This is late but the answer is 100%
Explanation:
I got a 100 on the test
The percentage of the offspring that will exhibit red, long-stemmed flowers is 100 percent; that is the last option as all of the offspring will show dominant traits, which are red, long-stemmed.
What is genetic crossing?In the context of genetics, traits are characteristics that are passed down from parents to offspring through their genetic material (DNA). These traits are determined by genes, which are segments of DNA that contain the instructions for the development of a particular characteristic. Here, the gene for flower color in roses has two alleles: R (red) and r (white). The R allele is dominant, and the r allele is recessive. Similarly, the gene for stem length has two alleles: L (long) and l (short). The L allele is dominant, the l allele is recessive, and from the cross, all will be dominant.
Hence, the percentage of the offspring that will exhibit red, long-stemmed flowers is 100 percent; that is the last option.

Genes exit the nucleus and go to ribosomes, where proteins form. C. Genes contain codes that specify proteins, which produce traits. D. Genes unwind and become templates, where amino acids can line up.
Answer:
C
Explanation:
The genes contain codes that specify proteins, which produce traits.
Genes contain codes that specify proteins, which produce traits best describes how genes are able to produce a organism's traits.
What is a gene?Genes are segments of DNA that contain the instructions for making proteins, which are complex molecules that perform a wide variety of functions in the body. Proteins are made up of chains of amino acids, and the specific sequence of these amino acids is determined by the code contained in a gene. Different versions of a gene, called alleles, can produce different sequences of amino acids and therefore different proteins, which can lead to different traits in an organism.
Genes are found in the nucleus of cells, and the process of making proteins begins when a gene is transcribed into a molecule called RNA. This RNA molecule exits the nucleus and goes to ribosomes, which are the site of protein synthesis. At the ribosomes, the RNA molecule serves as a template for the synthesis of a protein, with the specific sequence of amino acids being determined by the code contained in the RNA molecule. The protein is then folded into its characteristic shape, which allows it to perform its specific function in the body.
