Answer:
Respiratory system.
Explanation:
This is the system which shows a good pairing with the digestive system. This is because for energy to be synthesized by oxidative phosphorylation, respiratory systems need the supply of Oxygen. The oxygen is needed to accept the final electron in the synthesis of ATPs during oxidative phosphorylation.
This process begins with substrate level phosphorylation-glycolysis- the breaking down of glucose from the digestive system.
Hence, respiratory system needs the supply of oxygen for the metabolisms of glucose obtained from digestive system to generate energy( extract the energy in glucose) for the body.

How do the circulatory and respiratory systems play a role in track and field?
Answer:
Track and field requires a lot of running
Explanation:
When someone runs, blood needs to be circulated throughout the whole body. Constant blood is pushed throughout the body due to blood vessels in our circulatory system. The heart pumps faster so more blood is produced. Oxygen is needs to be reached to muscles. When someone runs, they tend to breathe heavier. Heavy breathing and more breathing is done by the respiratory system. Lungs need to filter air and therefore the respiratory system works hard as well

In a bacterial cell the genes are free in the cytoplasm. In what cell structure are the genes in plant and animal
cells?
Answer:
Nuclues
Explanation:
fun fact : What is the difference between a bacterial cell and an animal cell?
Nucleus: The most important difference between a bacterial cell and animal cell is that the bacterial cell does not have a membrane-enclosed nucleus. Instead, the bacterial cells keep its genetic material in an irregularly spaced region called nucleoid.
In plant and animal cells, the genes are present inside the nucleus, because these cells are eukaryotic.
What are eukaryotic cells?Any cell or creature with a distinct nucleus is said to be a eukaryote. The nucleus of a eukaryotic cell, which houses the well-defined chromosomes (bodies holding the genetic material), is surrounded by a nuclear membrane.
Eukaryotic cells are found in fungi, plants, mammals, and protozoa. They are categorized as belonging to the Eukaryota kingdom. DNA is tightly coiled around histone protein clusters in eukaryotic chromosomes. Prokaryotic cells generally have much less genetic material than eukaryotic ones.
The bacterial cell is prokaryotic, due to which they don't have a well-defined nucleus and genes are free in the cytoplasm. Plant and animal cells are eukaryotic. Hence, their genes are present inside the nucleus.

1. In a nuclear power plant, where does nuclear fission occur?
Answer:
nuclear fission reaction takes place in nuclear reactor
Explanation:
Answer:
Nuclear reactor
Explanation:
When an atom of nuclear fuel (uranium) absorbs a neutron, the uranium will fission into two smaller atoms (waste) and release one to three neutrons. The kinetic energy of the waste is used to heat the water for the steam turbine. The neutrons are used to fission the next lot of uranium atoms and the process continues.

Several proposals have been made to increase the use of renewable energy. Which of these will help most toward that goal?
Question 42 options:
Design cleaner burning coal fired power plants.
Reduce the use of plastics in the waste stream.
Increase the use of solar electricity generation.
Design cleaner methods for fracking for natural gas.
Answer:
Increase the use of solar electricity generation.
Explanation:
The correct option would be to increase the use of solar electricity generation.
Solar electricity is a form of electricity generated by capturing the energy from the sun using special device known as solar panel. The captured energy is stored in a chemical cell which is then used to generate electricity. Because the will always exist and unending, the form of energy derived from it is referred to as renewable.
Hence, increasing the use of solar electricity generation will lead to a corresponding increase in the use of renewable energy.
Coal burning and natural gas are non-renewable energy sources while reducing the use of plastics in waste streams have no bearing on increasing the use of renewable energy.

In dogs, wire hair is due to a dominant gene (W), smooth hair id due to its recessive allele.a. If a homozygous wire-haired dog is mated with a smooth-haired dog, what type of offspring could be produced?b. What types of offspring could be produced in F2?c. Two haired dogs are mated. Among the offspring of their first litter is a smooth-haired pup. If these two wire-haired dogs mate again, what are the chances that they will produce another smooth-haired pup? What are the chances that the pup will be wire-haired?d. A wire-haired male is mated with a smooth-haired female. The mother of wire-haired male was smooth-haired. What are the phenotypes and genotypes of the pups they could produce?
Answer:
a) All the offspring produced would be a heterozygous in the first generation (F1 generation) with genotype: Ww, Ww, Ww, and Ww. Since wire hair is dominant, all would be wired haired.
b) In the F2 (second generation), we breed the heterozygous offspring from the F1 generation together (Ww x Ww). This will produce 3:1 ratio of dominant:recessive phenotypes having 3/4 of the offspring wire-haired (1/4 WW homozygotes and 1/2 Ww heterozygotes) and 1/4 will be smooth-haired (ww). Also the genotype would have the ratio 1:2:1 (i.e 1 homozygote WW, 2 heterozygote Ww and 1 smooth hair)
c) the chances of producing a smooth-haired pup is 1/4, and the chances of producing a wire-haired pup are 3/4.
d) Therefore, 1/2 of the offspring will have the genotype Ww and be wire-haired, and 1/2 of the offspring will be ww and be smooth-haired. Also the phenotype ratio is 1:1 (1/2 is heterozygote wired hair and 1/2 is smoth haired)
Explanation:
Since the wire hair is the dominant gene (W) and smooth hair (w) is the recessive allele
a) If a homozygous wire-haired dog is mated with a smooth-haired dog, All the offspring produced would be a heterozygous in the first generation (F1 generation) with genotype: Ww, Ww, Ww, and Ww. Since wire hair is dominant, all would be wired haired.
b) In the F2 (second generation), we breed the heterozygous offspring from the F1 generation together (Ww x Ww). This will produce 3:1 ratio of dominant:recessive phenotypes having 3/4 of the offspring wire-haired (1/4 WW homozygotes and 1/2 Ww heterozygotes) and 1/4 will be smooth-haired (ww). Also the genotype would have the ratio 1:2:1 (i.e 1 homozygote WW, 2 heterozygote Ww and 1 smooth hair)
c) If two wire-haired dogs produce a smooth-haired pup, that means that both parents must be heterozygotes (Ww) having a pair of dominant W allele and recessive w allele to pass on to the offspring. Therefore, if these two dogs were to mate again (Ww x Ww), the chances of producing a smooth-haired pup is 1/4, and the chances of producing a wire-haired pup are 3/4.
d) If the mother of the wire-haired male was smooth-haired, that means that the recessive allele w had been passed on to the male making the male a heterozygote (Ww). When this male mates with a smooth-haired female (ww), the cross is Ww x ww. Therefore, 1/2 of the offspring will have the genotype Ww and be wire-haired, and 1/2 of the offspring will be ww and be smooth-haired. Also the phenotype ratio is 1:1 (1/2 is heterozygote wired hair and 1/2 is smoth haired)

Define the mechanical differences of elastin and collagen then explain the influence of these differences on tensile strength of skin
Answer:
Collagen is produced in the human body until natural aging occurs, whereas elastin is mainly produced during the fetal period. Collagen has the main property of providing structures with strength, whereas elastin will allow the structures which contain it to stretch and return to their initial form without damage
From what I know, collagen/elastin ratio as well as the collagen and elastin structures change with age [3,4,5,6]. The elasticity of the skin increases with atrophy of the collagen fiber bundles, the related flattening of the rete ridges, and the thickening of the dermal elastic fiber.
