B. decrease the production of aldosterone
C. decrease arterial blood pressure
D. decrease water absorption
Answer: A. constrict arterioles and increase blood pressure
Explanation:
Angiotensin II, is a hormone that binds to many receptors in the body to affect several systems. It can cause constricting of the blood vessels, increases thirst, stimulates the secretion of the hormone that is involved in the fluid retention in the body.
The angiotensin may cause vasoconstriction directly and indirectly. When the angiotension II levels are increased in the blood due to the activation of the renin-angiotension-aldosterone system, many arteries experiences the vasoconstriction so as to maintain the blood pressure. This process reduces the flow of blood to the kidneys.
Angiotensin II primarily functions to constrict arterioles and increase blood pressure, making option A the correct answer. It does this by constricting blood vessels, thereby increasing peripheral resistance and blood pressure.
The function of angiotensin II is predominantly to A. constrict arterioles and increase blood pressure. Angiotensin II, a powerful vasoconstrictor, plays a crucial role in maintaining blood pressure by constricting the arterioles to increase peripheral resistance, thereby increasing blood pressure. It is a part of the renin-angiotensin-aldosterone system, which helps regulate the body's blood pressure and fluid balance. So, decreased production of aldosterone, decreased arterial blood pressure, or decreased water absorption are not primary functions of angiotensin II. Its primary function concerns blood pressure regulation.

Answer: D
A lytic virus cycle leads only to cell lysis, and a lysogenic virus cycle involves phage genome integration into the host genome.
In lysogenic virus cycle,the virus DNA replicates itself using a host DNA while in lytic virus cycle,the virus replicates it's DNA and destroys the host cell.
Viruses undergo two(2) types of DNA replications which are lysogenic cycle or the lytic cycle.
In the lysogenic cycle, a bacteriophage virus makes it's way into a bacteria cytoplasm and deposits it's DNA.The DNA of the virus is further replicated by the bacterial proteins,this replication continues with the aid of the bacteria machinery until the virus DNA eventually switch to the the lytic cycle.
In lytic cycle,lots of the virus DNA are produced and encapsulated in capsids or proteins covers.
The capsids are further released into the environment to infect other bacteria and the cycle continues.
The phosphate is removed by hydrolysis from ATP molecules. Thus, energy is stored in the chemical bonds of ATP and released during ATP hydrolysis.
Further Explanation:
Adenosine triphosphate (ATP) is the molecular currency used for energy transactions. The ATP energy is stored in the bonds between the terminal phosphate groups. These bonds are hydrolyzed by the enzymes to obtain energy for reactions. ATP is an energy caring molecule present in the living cell. It stores energy in the bonds between the phosphates produced by the breakdown of food molecules. It releases energy required for the chemical reaction, and hence, it is known as an effective energy donor.
ATP is made of three main structures:
The main energy source in ATP is phosphate tail. The energy is stored in the bonds present between the phosphates groups and release when these bonds are broke down. This process is referred to as ATP hydrolysis in this addition of water occurs. When the one phosphate is removed from ATP, then it is converted into ADP.

Answer:The correct option is C) Cell walls are rigid. Small molecules like water or oxygen can pass through them.
Explanation:
Cell walls are found in plant cells and some other organisms. They provide structural support and protection to the cell. The cell wall is made up of a rigid material called cellulose, which gives it its strength.
Cell walls are permeable, meaning that they allow certain substances to pass through them. Small molecules like water and oxygen can pass through the cell wall via small pores or channels. However, larger molecules, such as proteins and carbohydrates, cannot pass through the cell wall.
This selective permeability of the cell wall allows the cell to control the movement of substances in and out of the cell, maintaining its internal environment. It also helps prevent the cell from bursting under osmotic pressure.
In summary, cell walls are rigid structures composed of cellulose. They are permeable, allowing small molecules like water and oxygen to pass through, while blocking larger molecules.
