The answer is C. The distribution of traits in a population
If a planet exists near a distant star, the star may have a very slight back and forth motion.
1) To calculate the population density you first need to know how many <span>squirrels form that population.
To calculate the number of</span><span> squirrels:
1500</span> squirrels is the capacity, so it's equivalent to 100%
So how much squirrels are present in 80% of the area:
1500----100 %
x----------80 %
x= 1200 <span>squirrels
</span>
2)Population Density equals the number of squirrels divided by the land area
In the first part was calculated the number of squirrels and the exercise gives us the area in hectares so the only thing left to do is divide them.
(since this exercise doesn't specify that the area needs to be in a certain measurement we can use hectares)
Population Density = 1200/ 150
<span>The population density of the squirrels is 8 per hectare</span>
<span>It
is important that antibodies have a symmetrical quaternary structure to create
two identical binding sites for antigens. An antibody is a relatively large
protein having a Y-shape. Plasma cells produce antibodies which are then used
by the immune system to fight off pathogens (e.g. bacteria and virus). The antibody
is able to recognize the antigen of the pathogen. It binds with it either to
neutralize it directly or “tag” the microbe for future attack by other parts of
the immune system. </span>
Answer: open more frequently to allow water and CO2 into the leaf tissue.
Explanation: Oxygen and C02 enters into the leaves to gives energy and sugar as food,to enable the plant to grow.
It allows the process of photosynthesis. Photosynthesis is the process whereby green plant and other orgasm manufacture light into chemical energy. Plants through the opening of the leaves breath in carbon dioxide and breath out oxygen. While animal in the other hand breath in oxygen and breaths out carbon dioxide.
The continuous opening and closing of stomata is responsible for photosynthesis.
