As a matter of terminology, albino guinea pig actually refers to a white fur guinea pig, whose genotype is homozygous recessive (bb).
If it crossed with a black fur guinea pig and gave 5 black fur offsprings, there is a good chance that the black fur parent is homozygous dominant (BB).
The Punnett square would be as follows:
B B
b Bb Bb
b Bb Bb
So they are all heterozygous black fur offsprings.
However, it is not impossible that the black fur parent be heterozygous, namely
B b
b Bb bb
b Bb bb
Giving a 50% chance on each colour. Thus it is possible (with probability 1/32) that all five offsprings are heterozygous black fur if one of the parents was heterozygous.
In the second case, a homozygous recessive and a homozygous dominant parent will never give a white offspring. So it is sure that the black fur parent is heterozygous, with the following Punnett square:
B b
b Bb bb
b Bb bb
With a 50% probability for each of Bb (black fur) and bb (white fur).
the distribution 4,3 demonstrates this perfectly.
Answer:
C) neurons - nerve tissue - brain - central nervous system - human being
Explanation:
This is due to the neurons being the smallest part so they have less inside, while the human body is composed of so many things inside making studying it complex.
The main function of environmental policy is to <u>reduce human impact on the environment (B).

<h3>Further explanation

Humans impact the environment in so many ways such as overpopulation, overfishing, pollution, and deforestation. This condition leads to many other problems: poor air and water quality, climate change, and soil erosion. Increasing population means increasing demand for consumption that may destroy the natural resources and environment.
The government or an organization creates environmental policies to regulate environmental issues and to reduce human impact on the environment. According to McCormick environmental policy is “any action deliberately taken to manage human activities to prevent, reduce, or mitigate harmful effects on nature and natural resources, and ensuring that man-made changes to the environment do not have harmful effects on humans or the environment.”
The policy regulates the use of resources and to reduce pollution to promote human welfare and protect natural resources. Some example of environmental policy, governments forbade the use of hazardous substances in agriculture or apply maximum emission levels for the industry to ensure minimum environmental quality.
