D. Dominant
It is dominant as...
The white coat alleles are recessive, meaning the black coat would most likely be dominant alleles. Assuming the black coated dog had the alleles of BB, and the white coated dog had the alleles ww, there would be a 100% chance that the offspring would have Bw alleles, where the black coat is dominant, "all the offspring were black".
B = Black, W = White
B B
w Bw Bw
w Bw Bw
The diagram above shows that the offspring would be 100% black coated.
Not sure if you wanted an explanation, but I tried.
The beetles that died were unable to avoid or detoxify the chemical and were thus killed by nerve poison insecticides.
- Chemicals called insecticides are used to kill insects or stop them from acting in an unwanted or destructive way. Their structure and mechanism of operation are used to categorize them.
- Most insecticides function by interfering with the insect's nervous system. The herbicide prevents neurotransmitters in synapses from transmitting information.
- Acetylcholine is the name of the substance that the body produces and uses to transmit information through synapses. Muscles can relax because of an enzyme called cholinesterase that binds to acetylcholine.
- Through the synapses, acetylcholine communicates with the muscles. The cholinesterase is impacted when a pesticide is administered at a deadly dose for a specific body, preventing it from binding with the acetylcholine.
- The muscles become overstimulated as a result, which will cause paralysis and death.

<span>When Prophase is occur, during this stage, changes occur both in the cytoplasm and in the nucleus. Within the nucleus, the chromatin fibers become more tightly coiled and folded, forming discrete chromosomes that can be seen with the light microscope. The nucleoli disappear. Each duplicated chromosome appears as two sister chromatids joined together, with a narrow waist at the centromere.In the cytoplasm, the mitotic spindle begins to form as microtubules rapidly grow out from the centrosomes which begin to move away from each other.</span>
Answer:
Much of the coordination of vertebrate body functions via chemical signals is accomplished by the brain
Explanation:
The central nervous system which makes up the brain and spinal cord coordinates body functions of vertebrates via chemical signals through the nerve cells
