how does the cytoskeleton help maintain cell shape?

Answers

Answer 1

Answer:

Of the three types of protein fibers in the cytoskeleton, microfilaments are the narrowest. ... Microfilaments also provide some rigidity and shape to the cell. They can depolymerize (disassemble) and reform quickly, thus enabling a cell to change its shape and move.

What happens to hydrogen bonds when water turns to ice? 9.) Why doesn't water break down fat? 10.)Which property of water causes surface tension? Cohesion, Adhesion, High heat capacity, high heat vaporization and polarity

Answers

Answer:

1. polarity

2. hydrogen bonding

3. High heat capacity

4. Adhesion

5. polarity

6. surface tension

7. high heat vaporization

8. hydrogen bonds form a rigid and stable network

9. Water is a polar substance and fat is a nonpolar substance.

10. Cohesion

Explanation:

Water is a polar molecule that is held together by hydrogen bonds to form strong cohesive forces. This accounts for the surface tension in water. Surface tension is the force acting on water that it makes to behave like a stretched elastic skin.

The polarity of water accounts for the fact that it is found in several parts of the body where it largely plays the role of a polar solvent.

High heat capacity of water enables it to function well in the area of thermoregulation in the body. High heat vaporization accounts for the fact that water helps maintain extreme temperature changes in an area.

When in solid state, the hydrogen bonded network in water becomes rigid and forms a very stable network of water molecules. Being polar, water does  not interact with fat because like dissolves like.

In plants, the attachment of water to plant roots is known as adhesion and is necessary for the capillary movement of nutrients to plants via the root.

HIV can remain latent for several years and not cause any symptoms in its host. What viral reproduction cycle is occurring during this latency period? What viral reproduction cycle is occurring once a person moves into the acquired immunodeficiency syndrome (AIDS) stage of HIV infection?

Answers

Answer:

The lytic cycle.

Explanation:

HIV is a retrovirus that has a special enzyme called transcriptase reverse, which can synthesize DNA using RNA as a template. This replication system is particularly useful for the virus because the DNA synthesized from the RNA viral genome can be then integrated into the human chromosomes and stay inactive for years. This is called a lysogenic cycle and is characterized by a latency of the virus and an integration to the host DNA.

When there is a triggering event, this latent virus can be excised from the human chromosome and start producing copies of itself using the host machinery. Then the virions are assembled and after that they lyse the host cell and release new infective units that can then infect neighboring cells. This is called the lytic cycle of the virus and is the reproduction cycle that occurs when a person moves into the acquired immunodeficiency syndrome (AIDS) stage of HIV infection.

Freezing is a phase change by which a liquid changes to solid.

Sublimation is a phase change in which a gas changes to solid.

Phase changes by which a substance returns back to the state of orderliness involves a loss of heat. Sublimation is can be from solid to gas or gas to solid. In the process from gas to solid, heat is released. But from solid to gas, heat is absorbed.

When a food handler can effectively remove soil from equipment using normal methods, the equipment is considered what?

Answers

Answer:

Cleanable

Explanation:

Cleanability refers to the ease with which microorganisms or particles can be removed from the equipment used in food production. To be cleanable the roughness of the machine being employed in production is not expected to exceed 0.8μm.

The Atomic Force Microscope is used to measure the surface roughness of machines. Cleanability is important as it ensures that the machines used in food production are safe.

When a food handler can effectively remove soil from an equipment by using normal methods, the equipment is considered to be; Corrosion Resistant.

The soil referred to her would be dirt because we are talking about a food handler.

Now, if the food handler is finding it difficult to remove dirt from the equipment by using normal/regular methods, it means that the soil/dirt has succeeded in having some kind of chemical reaction with that equipment.

If that is the case, then it means the equipment is undergoing corrosion because corrosion is defined as the gradual destruction of a metal by chemical reaction with the environment.

Since we have established that inability to use normal method denotes corrosion, then if he can use normal methods to remove the soil effectively, then the equipment is said to be corrosion resistant.

How many more cherry pies have 60 to 89 cherries than 90 to 119 cherries?

Answers

Answer:

They are the same thing

6 pies are more in 60 to 89 cherries than 90 to 119 cherries, a bar graph is a graphical depiction of information, amounts, or numbers using bars or strips.

How to depict the bar graph?

They are employed to contrast and compare various data kinds, frequencies, or other measurements of several categories of data.

The calculation of the bar graph in the given question.

For 60 - 89 cherries there are 10 pies

For 90 -119 cherries there are 4 pies

10 -4 = 6  pies

The image for the graph is attached below.

When displaying sections of data, bar charts should be used. As long as there aren't too many categories to compare, vertical bar charts can be useful for comparing several categories or discrete data, such as age groups, classes, schools, etc. They are quite helpful for time series data as well.

Therefore, there are 6 more pies in the 60 -89 cherries category than in the 90-119 category.

Pea plant clones are given different amounts of water for a three-week period. First pea plant receives 400ml. Second pea plant receives 200ml. Third pea plant receives 100ml. Fourth pea plant does not receive any extra water; the plant only receives natural ways of receiving water. The height of the pea plants is recorded daily. What is the independent variable?


A) the different amounts of water

B) the heights of the pea plant

C) the pea plants

D) the natural ways of receiving water

Answers

Answer: The independent variable is the different amount of water. The correct option is A.

Explanation:

A variable can represent age, a person, or an entity that can be measured. In statistics, it is simply defined as an attribute of an object to be investigated. There are different types of variables these includes:

--> Dependent variable and

--> Independent variable.

Dependent variables are simply the variables that are affected by the changes that occurs in the experiment. From the experiment they should include:

--> the height of the plant,

--> the size of the plant,

--> the number of leaves

---> if the plant survived or not (dead).

Independent variable are the variables that are changed in the experiment. A good example from the pea plant experiment is WATER. It is the aspect that is used to alter the dependent variable which is the height of the pea plant. I hope this helps, thanks!

Mitochondria require glucose to convert ADP to ATP. Which of the following statements describes how ADP is converted into ATP?

A. ADP loses a phosphate group which stores energy for use by the cell.
B. ADP gains a phosphate group which stores energy for use by the cell.
C. ADP loses a phosphate group which releases energy for use by the cell.
D. ADP gains a phosphate group which releases energy for use by the cell.

Answers

Answer:

B. ADP gains a phosphate group which stores energy for use by the cell.

Explanation:

ADP is converted to ATP for the storing of energy by the addition of a high-energy phosphate group. The conversion takes place in the substance between the cell membrane and the nucleus, known as the cytoplasm, or in special energy-producing structures called mitochondria.

The statement that describes how ADP is converted into ATP is as follows:

ADP gains a phosphate group which stores energy for use by the cell.

Thus, the correct option is B.

What is ATP?

ATP stands for Adenosine triphosphate. It may be defined as an organic compound that delivers energy to operate many processes in living cells, such as condensate dissolution, muscle contraction, nerve impulse propagation, and chemical synthesis.

ATP is considered a high-energy compound that furnishes immediate energy to the cell for metabolic activities.

ADP gets converted into ATP by gaining one phosphate group which is the most potent high-energy phosphate. This conversion of ADP to ATP generally takes place in the cytoplasm or in the membrane-bound cell organelle known as mitochondria.

Therefore, the correct option for this question is B.
