Answer: a. express different genes.
Explanation:
The nerve cells is functional for controlling the coordination of the body, respond to the external stimuli, voluntary actions in the body. The muscle cells contract and relax to facilitate the locomotion.
All the somatic cells of a living being have the same genomic make up. However, completely differentiated cells of particular tissue lineages express distinct genes, as required so as to perform specialized functions in the body.
If the question is how many of the offspring will have tortoiseshell coloring (XOXo), the answer is 2 in 4.
Let's take a look at that cross:
Parents: XOXO x XoY
Offspring: XOXo XOY XOXo XOY
The offspring will look like this:
Of total 4 offspring, 2 female cats that <span>have tortoiseshell coloring (XOXo), and 2 male cats with orange coloring.</span>
<span>In general, most dna viruses multiply in the host cell's NUCLEUS, while most rna viruses multiply in the host cell's CYTOPLASM. </span>
<u>ANSWER:</u>
'Adaptations enhance survival' is true about all adaptions.
<u>EXPLANATION:</u>
- Adaptation is a mechanism in organisms that allows them to adjust with the changes in their current environment or to adapt to their new environment.
- Darwin explained this as a concept of a natural selection process where organisms are susceptible to the variations with the environmental changes.
- These variations which are associated with greater survival and reproductive success are retained in the progeny. This phenomenon is known as Darwinian fitness.
A contaminant is any environmental agent -biological,chemical or physical that causes damage.
