This
is a specific response because in order to fight antigens, white blood cells,
the most important cells of the immune system, must produce large, Y-shaped
proteins known as antibodies to fight these invaders. This is a type of
specific defense (as I have identified antibodies as specific defenses is the
chart above).

Answer:
The cell is the smallest structural and functional unit of living organisms, which can exist on its own.
Explanation:
Oh I know this, It narrows down its characteristics here is an example:
The first step in the key will be organized the following way:
1. a. wings covered by an exoskeleton
b. wings not covered by an exoskeleton
Next, the statements need to lead the observer to the next step to narrow the identification further:
1. a. wings covered by an exoskeleton go to step 2
b. wings not covered by an exoskeleton .go to step 3
Step 2 needs to consist of a pair of statements that will allow for the identification of the ladybug and the grasshopper:
2. a. body has a round shape .ladybug
b<span>. body has an elongated shape .grasshopper</span>
Answer:
Disruptive selection
Explanation:
According to the infographic that is attached below showing different the three main types of selection that occurs as a result of natural selection taking its course on any population, we can draw our conclusion regarding the information given to us from the question.
From the question above, it states that the finches studied by Darwin are majorly finches with either small beak or large beak which are all adapted to suit the type of food available for the finches in the islands. Whereas, finches with intermediate beaks are favored against.
According to the infographic, disruptive selection can be said to have taken place as extreme traits are favored against intermediate traits on the islands.
The color change is most likely due to the effect of "<span>(3) environmental conditions on gene expression" All these changes have to do with what will keep the fox alive for the longest amount of time. </span>
