Answer: Since 81 mice have black fur, around 63.28% (Approx. 68.3%) of the mice have black fur.
Explanation: Evaluate the question carefully. We have a population of 128 mice, and 47 of them have gray fur, and the rest have black fur. That means that the other mice, besides the 47, have black fur.
To calculate percentages, I come up with proportions. 81 black fur mice over the total mice is equal to x over 100.
To solve the proportion, cross multiply and then divide.
Round your answer to the nearest tenth.

<span>One parent is an albino with the genotype aa (recessive homozygous), while another parent has genotype AA (dominant homozygous). If they mate:</span>
<span>
Parents aa x AA</span> F1 generation: Aa Aa Aa Aa <span><span>
This means that </span>c. all offspring are normal.</span>
<span>All of them are carriers of the albino allele (a), but albinism is expressed only when there are two recessive alleles.</span>
The correct statement about glial cells and their function is given below:
- Astrocytes participate in the formation of the blood-brain barrier.
<h3>What do you mean by Glial cells?</h3>
Glial cells may be defined as any of the cells that hold nerve cells in place and help them.
Astrocytes may even form barriers to the spread of neurotransmitter substances released as synapses. It tends to participate in the composition of the blood-brain barrier.
Oligodendrocytes are responsible for the formation of the myelin sheath of nerve fibers in the cells.
Schwann cells myelinate axons not dendrites in the PNS.
Therefore, it is well described above.

Answer:
Scientists try to figure out how the natural world works. In doing so, they use experiments to search for cause and effect relationships. Cause and effect relationships explain why things happen and allow you to reliably predict what will happen if you do something. In other words, scientists design an experiment so that they can observe or measure if changes to one thing cause something else to vary in a repeatable way.
