This is an example of evolution through natural selection. The peppered moths started off with a light color scheme when the industrial revolution started, and they had this to blend into the trees. The better the moths could blend in, the less likely they were to be preyed upon. Once the trees changed colors, the light moths were vulnerable. The months that thrived in this change were the darkly colored moths. These moths then bred and spread their dark color pattern to best fit into the new environment.
<h3><u>Answer and explanation;</u></h3>
- DNA is a double stranded molecule. Covalent and hydrogen bonds pray important roles in the functioning of DNA molecules.
- <em><u>Covalent bonds occur within each linear strand and strongly bond the nucleotide bases, sugars, and phosphate groups occurring both within each component and between components.</u></em>
- <em><u> Hydrogen bonds occur between the two strands and involve a base from one strand with a base from the second in complementary pairing.</u></em>
- Hydrogen bonds helps the complementary base pairs in DNA; guanine with cytosine and adenine with thymine to connect to one another. The hydrogen bonds between these complementary pairs helps keep the two strands of DNA helix together.
Answer:
True
Explanation:
Sensory neurons are the neurons present in the nerves which can convert the external stimuli into an electrical signal and can transmit the signals from the organs to the central nervous system.
The structure of sensory neuron in pseudounipolar that is at one end it has dendrites and another end transmits the signals to the CNS.
The cell bodies (nucleus) of these sensory neurons are located in the structures called ganglia located outside the CNS.
Thus, True is the correct answer.
Answer:
The answer is letter D, The storms cause wind and waves that move the sand from one place to another.
Explanation:
Along the coastline of Florida are their <em>beaches and barrier islands. </em><u>These islands are very important for the survival of plants and animals. </u>However, whenever a hurricane or a storm hits the area, it causes a dramatic change in the shape of the place. This is, primarily, because the storm causes the forces of wind and waves to move the sand from one place to another.
The movement of these can be towards or away from the mainland. <em>The fast movement</em> <u>causes the sand in the area to be deposited away from the shore,</u> thus creating sandbars. <em>The slow movement</em> <u>causes the sand from the sandbars to return back to the shore.</u>
No, because it could clot to much in the patient it's going to and could cause other problems.
