C...the animals will be attracted to eat the fruit and then spit out the seeds causing new life to grow
Answer: All of these
Explanation:
The polymerase chain reaction (PCR) revolutionized the field of molecular biology because PCR uses a small amount of DNA as a template.Paired with two primers which side to the target sequence, nucleotides, and thermostable DNA polymerase amplifies a specific region of DNA. In this way a large amount of DNA is obtained from a very small sample.
These other stimuli are known as s - deltas.
<h3>What is an example of a stimuli?</h3>
Anything that can cause a change in behavior or physical state is a stimulus. Stimuli is the plural of stimulus. External or internal stimuli can be used. The way a medication affects your body is an illustration of an external stimulus. Your vital signs altering as a result of a change in your body is an example of an internal stimulus.
<h3>Which 3 stimuli are they?</h3>

Answer:
b). activation of T cells
Explanation:
An APC (antigen-presenting cell) can be described as an immune cell, which detects, uptakes, and informs the acquired immune response when an infection takes place. B cells, macrophages, and dendritic cells are antigen-presenting cells.
These cells play an important role in activation of T cells. T cells are unable to recognize soluble or free antigens and can only recognize antigens processed and presented by carrier molecules, such as MHC molecules.
Presence of MHCII molecules is a defining feature of APCs that process and present antigens to T cells. Hence, all antigen-presenting cells help in activation of T cells.
Thus, the correct answer is option (b).
Statements that surround a word that help to explain its meaning are called CONTEXT OR CONTEXT CLUES.
The meaning of a word can be derived from the context clues that surrounded it. A word may have different meanings depending on the type of context in which it is found.<span />
