Out of the following given choices;
(1) an increase in the number of clams
(2) a decrease in the number of water plants
(3) an increase in the number of crabs
(4) a decrease in the number of crayfish
The answer is D. Crayfish are are freshwater crustaceans resembling small
lobsters. Clams and crabs are found in marine waters. Most crayfish cannot
tolerate polluted water. Crayfish feed on animals and plants, either living or
decomposing, and detritus, therefore a decrease in small invertebrates in the river
would decrease their food source thence
consequently affect their numbers.
Answer:
Corbin recently found out that he has cancer, and he now strictly follows a treatment, diet, and exercise program that the doctor thinks will be helpful in keeping the cancer from spreading. These behaviors best illustrate <u>problem-focused</u> coping.

The correct statement about glial cells and their function is given below:
- Astrocytes participate in the formation of the blood-brain barrier.
<h3>What do you mean by Glial cells?</h3>
Glial cells may be defined as any of the cells that hold nerve cells in place and help them.
Astrocytes may even form barriers to the spread of neurotransmitter substances released as synapses. It tends to participate in the composition of the blood-brain barrier.
Oligodendrocytes are responsible for the formation of the myelin sheath of nerve fibers in the cells.
Schwann cells myelinate axons not dendrites in the PNS.
Therefore, it is well described above.

Answer: Option A) overexploitation
Explanation:
Overexploitation refers to the excessive consumption or usage of a particular resource(s) that is vital to the survival of living organisms.
Examples of resources that have been overexploited are:
- Forest trees
The uncontrolled falling of trees has deprived many animals (terrestrial and arboreal such as birds, monkey etc) shelter and food. Thus, their species has greatly reduced.
- Water
Human use of water and activities in rivers has led to the drying up of several water bodies forcing several species of aquatic organisms to struggle for survival, or even die and become extinct.
Others include atmospheric gases like oxygen, nitrogen, carbon etc
Thus, overexploitation is the single greatest threat to biological diversity
