Because of the tortoises that were on the islands they had adapted to their surroundings for food so their necks got longer.
The answer to this question would be simple squamous epithelium.
When you need to supply oxygen or nutrient, the thinner cell layer the faster it can move. In this case, simple squamous epithelium is better since it provides protection but can let the nutrient transported quickly.
E because i looked on quizlet idk look up the answer sorry
Answer:
The given statement is false.
A neuron is the basic structural and functional unit of the nervous system. It helps in transmitting information from one neuron to another neuron, gland, or muscle cell.
The conduction of nerve impulse is electrochemical in nature. It transmits the impulse electrically through the axon the nerve cells and chemically through synapses (gap between two nerves cells).
The axon terminals of pre-synaptic nerve cell release chemical messengers (also called neurotransmitters) in the synaptic cleft. These messengers then bind to the receptors present on the post-synaptic nerve cell and regenerate the nerve impulse.
The answer is C. The dark moths were best fit for their environment, since the trees in England were darker due to pollution. The dark moths could best blend into the trees, so birds couldn’t spot them. The white moth population decreased dramatically because they could not blend in with the trees, so they were spotted easier and were thus more vulnerable to predation. This illustrates Darwin’s concept of survival of the fittest. The organisms best fit for the environment live because they have traits and adaptations that enable them to survive. The organisms that do not have these traits, however, will not survive. Since the fit organisms live, they can reproduce and pass on their fitness to their offspring. That’s what makes a species stronger and less vulnerable in their environment. This leads to evolution.
