in muscle, what does the source of atp depend upon? multiple choice question. the duration of exercise the size of the muscle the location in the body the number of fast glycolytic fibers
In muscles, the source of ATP depends on the duration of exercise.
The duration of exercise is an important factor in determining the source from which ATP is derived in the muscles.
Initially, when there is enough supply of oxygen, the body will use the method of aerobic respiration for the production of ATP. By the aerobic method, carbohydrates, fats and proteins derived from the food can be used as an energy source.
When the time duration increases, the muscles will switch to anaerobic respiration as there will not be a shortage of oxygen. In this case, energy will be derived from glucose that we get from the breakdown of glycogen. Glycogen is the form in which energy is stored in the body.
Hence, the source of ATP will be dependent on the duration of exercise.

4. Which limiting factor impacted the cricket frog population the least? Use evidence to support your answer.
Pollution is the factor that least affected the frogs population size.
5. Mosquitoes can carry and transmit disease to animals and humans. Explain how the cricket frog plays an important role in limiting the spread of mosquito-borne illnesses like West Nile virus and malaria.
Since frogs feed on mosquitoes, they become a natural control species for the mosquitoes, limiting their spread and effects on humans and animals.
Frogs are a biotic limiting factor for moesquitoes population.
6. Predict the long-term effects of these limiting factors on the cricket frog population in the pond ecosystem.
It depends on the pond ecosystem.
If there are too many alligators, frogs population will decrease. This decrease will probably affect alligator population size (assuming no other source of food for this last species), and only when predator population size decreases, frogs population will increase again. If there are too many mosquitoes, frogs population will increase, which will cause a decrease in mosquitoes population. Less mosquitoes will drive to less frogs. The decrease in the number of frogs will increase the number of mosquitoes again.↑ alligators and ↑ mosquitoes ⇒ ↓ frogs

The ability of carbon to catenate and the fact that it has low bond energy accounts for the fact that it forms large, complex structures of organic compounds.
What are complex organic compounds?The complex organic compounds are those compounds that are composed of carbon but they do have a very large macromolecular structure. These compounds are found in the body as well as are useful in the industry. A common example of a very large macromolecule which plays a very important role in the body is the biological molecule that we call cholesterol which is largely macro molecular.
There are several reasons that enables carbon to form these kinds of large and complex organic compounds;
1) Low bond energy: The carbon to carbon bond energy is very low and this enables carbon to link to itself many times.
2) Carbon does catenate: The ability of carbon to catenate makes the carbon atom able to link to itself in such a way that gives an infinitely large chain of carbon atoms.
3) Carbon does bond easily to hydrogen: The fact that the bond energy of the carbon hydrogen bond is low also makes it possible for carbon to bond to hydrogen in these large organic molecules.
4) Carbon bonds with electronegative atoms: It is common to observe that carbon is also able to bond with highly electronegative atoms thereby forming more compounds.

trematol is a metabolic poison derived from the white snake root. cows eating this plant concentrate the poison in their milk. the poison inhibits liver enzymes that convert lactic acid to other compounds for metabolism. why does physical exertion increase symptoms of poisoning by trematol? why does the ph of the blood decrease in a person who has digested trematol?
Here are the answers to the questions respectively:
Physical exertion increase symptoms of poisoning by trematol because the generation of lactic acid through fermentation, and when liver enzymes are inhibited, the accumulation of lactic acid lowers blood pH.The pH of the blood decrease in a person who has digested trematol because exercise stimulates metabolism, and blood pH rises as a result of the electron transport chain pushing H+ out of the mitochondria.A metabolic poison called trematol is made from the white snake root. The toxin is concentrated in the milk of cows that consume this plant. The toxin prevents the liver's enzymes from metabolizing lactic acid into other chemicals.
Our cells make lactic acid through a process known as fermentation when there is not enough oxygen present. Particularly in our muscles, the pyruvate from glycolysis is converted to lactic acid to replenish NAD+ from NADH, allowing glycolysis to continue producing ATP.

In roses assume that red or yellow flower color is controlled by a single gene with two alleles. Crossing roses with yellow flowers with each other yields only offspring that produce yellow flowers, but when you cross roses with red flowers with each other you sometimes get offspring that produce yellow flowers. If you take a rose plant that is heterozygous for the flower color gene and cross it with another rose plant with red flowers that has had yellow-flowered offspring in the past, what are the predicted fractions for the possible phenotypes of the offspring?.
The predicted fractions for the possible phenotypes of the offspring are 3/4 red and 1/4 yellow.
The genotypes of the offspring of this hybrid can be used to predict the proportions of phenotypes. Offspring with either the PP or Pp gene will have the red-flower phenotype because P is dominant to p.
The yellow-flower phenotype can only be inherited through the pp genotype. As a result, with this cross, you would anticipate that three of the four (75%) progeny will have red flowers and one of the four (25%) would have yellow flowers.
