Answer:
I believe the correct order of the eukaryotic gene expression, from beginning to end would be: (4), (1), (3), and then (2).
Explanation:
This is because in order to make RNA, you must have a "template," or DNA. (4) The DNA is then copied. (1) the mRNA is then transported out of the nucleus and into the cytoplasm where it is connected to ribosomes. (3) The mRNA is now in the ribosomes, so the ribosomes translate the mRNA and all the thymine bases would be replaced with uracil to make proteins. (2)

I believe that plant hormonal control differs from animal hormonal control in that there are no separate hormone-producing organs in plants as there are in animals. Hormones regulate cellular processes in targeted cells locally and moved to other locations, in other function parts of the plant. Hormones also determine the formation of flowers, stems, leaves, the shedding of leaves, and the development and ripening of fruit. Plants unlike animals they lack glands that produce and secrete hormones and instead each cell is capable of producing hormones.
Answer: 1. Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.
2. The changes in our behavioral patterns and adaptations that are caused by these technological advances could prove to be the primary driving forces behind the next stage of evolution for our species. These members of the species are more likely to reproduce and pass their genes on to their children.
Explanation:
The correct answer is (A) Chromosomes.
The color of the horse coat is determined by chromosomes. The genes present on the chromosomes is responsible for the coat color of horse. The dominant coat color of the horse is transferred to the horse from its parents. This is inherited pattern and the coat color can be black, white, brown, etc.
