Discuss what is respiration and why is it important.
Answers
Answer:
Respiration is the chemical process by which organic compounds release energy.
Explanation:
Respiration is important because it produces energy that is essential for the normal functioning of the body. Respiration provides cells with oxygen and expels toxic carbon dioxide. Some energy released by respiration is also in the form of heat.

2. A population of salamanders has two colors, blue and white. Blue is the dominant color and white is recessive. The frequency of the white allele is 36%. What percentage of the salamander population is white?
Answers
The percentage of the white salamander population is 16%.
Hardy-Weinberg Equilibrium EquationThe genotypic frequencies within a population can be expressed by the binomial (p + q)² = 1, which can be developed and represented by the following equation:
p² + 2pq + q² = 1p = frequency of the dominant allele;
q = frequency of the recessive allele;
p² = frequency of the zygous dominant genotype;
2pq = frequency of the heterozygous genotype;
q² = frequency of the zygous recessive genotype.
Also according to the equation presented (p² + 2pq + q² = 1), we will have the following distribution of genotypes:
CC = 0.36 = 36%Cc = 0.48 = 48%cc = 0.16 = 16%Learn more about recessive allele in brainly.com/question/844145

C. Medium-colored rabbits moved away from the area.
D. Medium-colored rabbits were not able to find food efficiently.
Answers
Answer: D
Explanation: I think it is d because of process of elimination. A is not reasonable because the graph 2000 goes up and down so not being able to reproduce would not fluctuate. The other two choices the. Are close but not sensible to how the graphs are structured. Therefore best choice is option is D.

how do the germinal discs differ between the eggs?why?
Answers
Answer:
Germinal disk (blastoderm) -- a small, circular, white spot (2-3 mm across) on the surface of the yolk; it is where the sperm enters the egg. The nucleus of the egg is in the blastodisc. The embryo develops from this disk, and gradually sends blood vessels into the yolk to use for nutrition as the embryo develops.

5. What would be the harm in having a captive animal intended for release imprinting on its human handlers?
Answers
Answer:
If we release a captive animal imprinted on human then the animal won't recognize other animals of its species as same as itself . It won't mate with its species rather it would try to mate with humans. It would not behave normally. The behaviour would not be typical of other members of its species.
How can a black hole tunnel to another universe
Answers
Answer:
According to a mind-bending new theory, a black hole is actually a tunnel between universes—a type of wormhole. The matter the black hole attracts doesn't collapse into a single point, as has been predicted, but rather gushes out a "white hole" at the other end of the black one, the theory goes.

Why are molecules clocks important to construction of cladgram
Answers
Answer:Molecular clocks are used to compare the number of mutations to determine how long ago a species separated and evolved.
Explanation: Yw.
Answer:
They compare the number of mutations to figure out when species split off and evolved.
Molecular clocks analyze the total amount of distinct nucleotides in two organisms' genomes to determine when they diverged from one another. The dates of evolutionary branch points are determined by the average pace at which a certain gene evolves. The molecular clocks compare the number of mutations to calculate how long ago species split and evolved in this way.

Where does the energy to create ocean waves come from? What happens to waves once the wind stops? How does the Coriolis effect impact Earth?
Answers
Answer:The Coriolis effect bends the direction of surface currents to the right in the Northern Hemisphere and left in the Southern Hemisphere. The Coriolis effect causes winds and currents to form circular patterns. The direction that they spin depends on the hemisphere that they are in.
Explanation:
I hope this helps
Volent miko<3
Answer:
Coastal currents are affected by local winds. Surface ocean currents, which occur on the open ocean, are driven by a complex global wind system. To understand the effects of winds on ocean currents, one first needs to understand the Coriolis force and the Ekman spiral.
If the Earth did not rotate and remained stationary, the atmosphere would circulate between the poles (high pressure areas) and the equator (a low pressure area) in a simple back-and-forth pattern. But because the Earth rotates, circulating air is deflected. Instead of circulating in a straight pattern, the air deflects toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere, resulting in curved paths. This deflection is called the Coriolis effect. It is named after the French mathematician Gaspard Gustave de Coriolis (1792-1843), who studied the transfer of energy in rotating systems like waterwheels.
