1) B
(I'm not so sure of this one) All of the other options have a steady impact on population regardless of the density of organisms except competition
2) D
Increased carbon dioxide levels would not hinder plant growth, and tsunamis aren't really linked to carbon dioxide levels. Increased carbon dioxide is unlikely to lower the air temperature so only D is left.
3) A
4) Three properties of water that allow it to sustain life are that it is adhesive, it is a good solvent, and cohesion. Adhesion is important in situations such as water travelling up xylem tubes in plants so that the water is not pulled down by gravity and can reach parts of the plant that need water. Cohesion allows the water being pulled up the xylem to stay together and for water molecules to be pulled when a neighbouring one is moved. Water being a good solvent allows inorganic minerals to be taken with water through vascular tissue, such as in the previous example.
Tortoiseshell females; black males are the kinds of offspring that I would expect from the cross of a black female and an orange male.
Explanation:
In the above question the cats of black for is caused by an allele which is linked in x. Also, we get to know that the zygote is heterozygote and it is of tortoise cell. The offspring contains the father of tortoise shell in females because of the xx zygote and the main contains black for because of the xy zygote.
It is known as dominance of the traits over the recessive traits. It also occurs in all the human beings and animals. The trait which is dominant is shown in the offspring and the trait which is recessive gets hidden. It can also be calculated through Punnett square.
The incorporation of a CD4+ Helper Epitope from Aquifex aeolicus enhances vaccine-induced humoral immunity by recognizing certain components of the immune system.
<h3>What are CD4+ Helper cells?</h3>
CD4+ Helper cells are CD4-positive cells of the immune system that trigger the body's responses to infections. These cells recognize epitopes (i.e., molecular domains) present in certain cells in order to trigger the humoral or cellular responses.
In conclusion, the incorporation of a CD4+ Helper Epitope from Aquifex aeolicus enhances vaccine-induced humoral immunity by recognizing certain components of the immune system.

#SPJ4
The answer is muscle weakness, fatigue and dysrhythmias. The distinctive indication of hypokalemia contains muscle faintness, leg spasms, fatigue, paresthesia and dysrhythmias. Indicators of hypercalcemia contain nausea, vomiting, constipation, bone pain, too much urination, dehydration, misperception, weariness and indistinct speech. Reduced cognitive capability and hypertension may outcome from hyperchloremia in which constipation is a indication of hypercalcemia.
Answer:
Explanation:
Cellular respiration is a process which occurs in the all living cell all the time. It is an oxidative process by which respiratory substrate such as glucose (C₆H₁₂O₆) is oxidised completely in presence of oxygen(O₂) to produce carbon dioxide (CO₂), water and energy in the from of ATP. ATP is is the energy currency of the cell. The process of cellular respiration begins in cytoplasm and completes in the mitochondria of the cell.
The overall reaction of respiration is given below:
C₆H₁₂O₆+ 6O₂ → 6CO₂+ 6H₂O + Energy (ATP)
