Answer:

Angiotensin II is a main effector of RAS and is produced due to the release of the renin that forms in the kidney, angiotensin in turn stimulates the release of aldosterone from the adrenal cortex.

Angiotensin II serves various roles other than vasoconstriction to maintain blood pressure that are:

1. Autoregulation of GFR

2. Reduction of salt excretion through direct and indirect actions on renal tubular cells,

3. Growth modulation of renal cells - these express AT1 receptors.

Explanation:

The hydrogen bonds between water molecules allow water to hold heat better than most substances. As the temperature surges, the hydrogen bonds between water; continually from thousands cracks and reforms, enabling the overall temperature to stay steady, although exceeding energy is added to the system.

Answer:

In order to form more DNA molecules.

Explanation:

These viruses carry the polymerase protein in the  virus particle because this protein synthesizes DNA molecules from deoxyribonucleotides. This formation of DNA molecule enables the virus cell to increase in their population. Each and every new cell of virus requires DNA molecules so we can say that this polymerase protein is very important and necessary for virus.

Answer: They cause the immune system to produce an exaggerated response, distracting it from the actual pathogen.

Explanation:

Superantigens are a type of bacteria that suppress the immune system by excessively activating it. They cause the creation of non-specific T-cells which then causes the body to look for other organisms apart from the pathogen.

With the immune system distracted, the pathogen then infects the body thereby making these pathogens particularly dangerous.

Answer:

b. A virus that infects bacteria.

Answer:

In turn, the brain tells your body how to stay balanced. If you're on a rollercoaster or a boat that's moving up and down, the fluid in your inner ears might take a while to stop moving. This is why you may feel dizzy for a little while even when you stop moving or are on solid ground. Dizziness caused by the inner ear may feel like a whirling or spinning sensation (vertigo), unsteadiness or lightheadedness and it may be constant or intermittent. It may be aggravated by certain head motions or sudden positional changes.

Explanation:

How do you fix dizziness in the inner ear?

1) Sit on the edge of your bed. Turn your head 45 degrees to the right.

2)Quickly lie down on your left side. Stay there for 30 seconds.

3)Quickly move to lie down on the opposite end of your bed. ...

4) Return slowly to sitting and wait a few minutes.

5) Reverse these moves for the right ear.

Explanation:

A hypothesis is a tentative statement about the relationship between two or more variables. It is a specific, testable prediction about what you expect to happen in a study.

Answer:

can cause large changes in enzymatic activity

Explanation:

An enzyme refers to a biological catalyst that is typically used to speed up (accelerate) the rate of a chemical reaction by lowering the activation energy of its reactants.

An allosteric effector can be defined as an agent, organ or molecule that is being binded to an enzyme at a site, thereby causing a reduction (negative effect) or an increase (positive effect) in an enzyme activity.

When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy.

Additionally, if the conditions are not optimal for an enzyme, it limits the ability of an enzyme to bind or be joined with its substrates.

Furthermore, an increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction.

In the human body, the optimal temperature for enzymes is around 37 degrees celsius (°C).

In conclusion, an allosteric effector can cause large changes in enzymatic activity because it acts as an intermediary and mediates specific effect in a metabolic pathway.

Zygote is the single cell formed from the fussion of male and female gamete.

Answer:

It controls the population of sea urchins.

Explanation:

Sea otters are very important in maintaining the balance of ecosystems present near the sea or ocean, such as kelp forests etc. In the absence of sea otters, sea urchins can increase in population i.e. overpopulate the sea floor and feed all vegetation of the kelp forests that provide cover and food for many other marine animals which leads to imbalance of an ecosystem so that's why we can say that sea otters are important in the kelp forest.

OPTION D will right

Answer:

The cellular process of releasing energy from food through a series of enzyme-controlled reactions is called respiration. Some of the energy released is used to produce ATP. Some of the energy released is lost as heat.

The larvae of a silk moth secrete the silk thread which is used to make clothes. Honey bees produce and store honey which is nutritious food. Silkworm is a creamy white colored insect which is about 2-3 cm long and shining in nature. Bee larvae have been shown to be an excellent food source for rearing insects

Explanation:

Since plants and fungi are both derived from protists, they share similar cell structures. Unlike animal cells, both plant and fungal cells are enclosed by a cell wall. As eukaryotes, both fungi and plants have membrane-bound nuclei, which contain DNA condensed with the help of histone proteins.

Answer:

phospholipids are composed of a phosphate group, two alcohols, and one or two fatty acids. On one end of the molecule are the phosphate group and one alcohol; this end is polar, i.e., has an electric charge, and is attracted to water (hydrophilic).

The battery component would Chang use as the source of energy.

Batteries consist of one or more cells, each of which undergoes chemical processes to produce an electron flow in a circuit.

Each battery has three primary components: an anode (the "-" side), a cathode (the "+" side), and an electrolyte of some sort.

When the cathode and anode of a battery are connected to a circuit, a chemical reaction takes place between the anode and the electrolyte. Following this reaction, electrons return to the cathode and experience a second chemical change.

Therefore, The battery component would Chang use as the source of energy.
