Answer:
The correct answer is D. some RNA viruses.
Explanation:
The enzyme reverse transcriptase (RT) is found in some retroviruses, such as HIV. It is a DNA polymerase, which converts the single stranded RNA of the virus into a double stranded DNA (retrotranscription process).
Breathing/movement, animals
Some methods of determining the size of population are direct and indirect observations, sampling, and mark-and-recapture studies
.
Sampling - Done by counting the animals in a small area and then estimating how many are in the larger area. You go out and take samples from different places so you can take the average. In most cases, it is not possible to count every member of a population so an estimate is made.
Mark and recapture - Another estimating method is a technique called "mark and recapture." This technique gets its name because some animals are first captured, marked, and released into the environment. Then another group of animals is captured. The number of marked animals in this second group indicates the population size.
Indirect observation - The members of a population may be small or hard to find. It may be easier to observe their tracks or other signs rather than the organisms themselves.
Direct observation - The most obvious way to determine the size of a population is to count, one by one.
Answer:
Answer is axon terminal.
Explanation:
The axon terminal is the end and the sending part of synapses. They are very important in releasing the neurotransmitters of the pre-synaptic cell and send them to post-synaptic dendrites found on other neurons.
This is possible because, the axon terminal vesicles full of neurotransmitters.
