Predict how an unusually prolonged drought might affect a biological community

1 answer:

6 0

Primary consumers (such as grazers and browsers) of the biological community will put pressure on the primary producers (these are plants) since the primary producers have limited resources (water) to reproduce due to the drought. The primary producers hence become scarce and cause the primary consumers to compete for limited resources. This causes the primary producers to reduce in population. Reduction in their population causes limited resources for secondary consumers and this cascades up the food web to tertiary consumers.

We can rule out small fish and grasses. My guess is that zooplankton get their energy from phytoplankton, because phytoplankton use photosynthesis to get their energy.

If the sperm cells of fish have 12 chromosomes how many chromosomes would be found in the cells forming the gills of the fish

lisabon 2012 [21]

Sex cells will always contain half of the number of chromosomes needed for a being. So if a fishes sperm cell contains 12 chromosomes and the ovum also contains 12 chromosomes then when fused together they will have 24 chromosomes in total.
In order for the process of the fish to even be made the sperm and ovum must be fused together. Therefore the number of chromosomes that would be found in the cells forming the gills is 24 chromosomes.

Peripheral resistance depends on all of the following factors except __________.

pantera1 [17]

Options for the question have not been given. They are as follows:

blood vessel length

blood viscosity

blood vessel diameter

blood colloid osmotic pressure

Answer:

blood colloid osmotic pressure

Explanation:

Peripheral resistance is the resistance to blood flow by blood vessels.
It is directly proportional to blood vessel length as more the distance to travel, more will be the resistance.
It is also directly proportional to blood viscosity as more energy is required to push viscous material.
It is indirectly proportional to blood vessel diameter. More the diameter of the vessel, easier it is for the blood to pass.
However, it does not depend on blood colloid osmotic pressure. Colloid osmotic pressure is created by the protein components of blood and they do not have any direct impact on blood flow.
