I am not 100% sure but I believe that because of increased manufacturing, the air got very polluted and this made many trees darker, like birch. So moths are usually lighter in color so many couldn’t really hide among trees and they were eaten. After some time, many moths mutated and also became darker to blend in when they were on trees to prevent being eaten by predators. In conclusion, the population decreased.

Answer:
The correct answer is a. Human papillomavirus
Explanation:
Human papillomavirus is the most common STI according to the center for disease control and prevention. It can pass from one people to another people from skin contact. They are responsible for causing condylomata( genital warts) in the patients.
The genital HPV infection is mostly caused by direct sexual contact with the infected person. HPV infection later can cause cancers like cervical cancer, genital cancer, throat cancer, etc if not treated properly.
Therefore students demonstrate an understanding of the material when they identify human papillomavirus as a cause of condylomata.
Peer review and repeated experimental outcomes
Answer:
Through genetic modification/engineering
Explanation:
<em>Most of the species that we use as food do not look like their ancestral species anymore because humans have genetically modified them to suit their desires.</em>
Through genetic engineering, humans have been able to select desirable characteristics or attribute from one organism and transfer it to another organism of similar species that already has some desirable attributes. Thus, the latter organism becomes genetically modified and looks different from its ancestors just to suit the taste of man.
Answer:
In chemical transmission the release of chemical messengers known as neurotransmitters occurs. Neurotransmitters carry information from the presynaptic or transmitter neuron to the postsynaptic or recipient cell.
As you may recall from the article on the structure and function of the neuron, synapses are usually formed between the nerve terminals - axon terminals - of the sending neuron and the cell body or dendrites of the receiving neuron.
Scheme of synaptic transmission. An action potential travels through the axon of the presynaptic or emitting cell, and reaches multiple axon terminals branching from the axon. The axon terminal is adjacent to the dendrite of the postsynaptic or recipient cell. This place of close connection between axon and dendrite is the synapse.
A single axon can have multiple ramifications, which allows it to synapse with several postsynaptic cells. Similarly, a single neuron can receive miles of synaptic inputs from many different presynaptic or emitting neurons.
Within the axon terminal of a transmitter cell there are many synaptic vesicles. These are membranous spheres full of neurotransmitter molecules. There is a small space between the axon terminal of the presynaptic neuron and the postsynaptic cell membrane, this space is called synaptic space.
