What functions do endocytosis and exocytosis carry out for the cell?

Answers

Answer 1
Answer:

Endocytosis and exocytosis are transport processes used by all cells to move particles that cannot pass through the membrane passively. Endocytosis moves particles into the cell by engulfing it with its membrane while exocytosis is mainly the opposite of endocytosis which pushes molecules out of the cell. Both endocytosis and exocytosis functions by regulating nutrients and waste for normal cell life and function.
Answer 2
Answer: Endocytosis uses vesicles to move there particles into the cell.

Exocytosis is basically the reverse of endocytosis. A substance is released from the cell through a vesicle

Name two types of cell that can go through the cell cycle an infinite amount of times

Answers

Answer:

red blood cells and nerve cells

Explanation:

The Hayflick Limit is a concept that helps to explain the mechanisms behind cellular aging. The concept states that a normal human cell can only replicate and divide forty to sixty times before it cannot divide anymore, and will break down by programmed cell death or apoptosis

this is for further explanation

Based on what you know about the six types of infectious agents, what type of agent do you think was plaguing Anna explain your reasoning

Answers

Infectious agents are those that corrupt and prey on an organism or a host. This is sometimes called parasitism when a foreign organism consumes a host by preying on its nutrients and food. Hence, we are uncertain in Anna's case because there is no clear description of her symptoms. 

Mitochondria and other organelles are manufactured in mitosis or interphase?

Answers

Organelles are manufactured and separated in mitosis.

Final answer:

Mitochondria and other organelles are formed through cellular respiration, not in mitosis or interphase.

Explanation:

Mitochondria and other organelles are not manufactured in mitosis or interphase. They are actually formed through a process called cellular respiration. Mitochondria are responsible for producing ATP, the energy currency of the cell, through a series of chemical reactions. Other organelles, such as the endoplasmic reticulum and Golgi apparatus, are involved in the synthesis, processing, and transport of various molecules within the cell.

What is the water cycle? A. It is the storing of water under, on or above the Earth's surface. B. It is the removal of water under, on or above the Earth's surface. C. It is the continuous movement of water under, on or above the Earth's surface. D. It is the creating of water under, on or above the Earth's surface.

Answers

The correct answer is going to be C. It is the continuous movement of water under, on or above the Earth's surface
I believe that the correct answer is C, there is precipitation, condensation, and evaporation

3) A variable that is kept the same during an experiment is a(n) __________.A. control variable
B. extraneous variable
C. control group
D. dependent variable
E. independent variable

4) A variable that is purposefully changed in an experiment is a(n) __________.
A. control group
B. independent variable
C. control variable
D. extraneous variable
E. dependent variable

5) A variable that is changed, depending on the change in the independent variable is a(n) __________.
A. dependent variable
B .control variable
C. control group
D. extraneous variable
E. independent variable

Answers

A variable that is kept the same during an experiment is a controlled variable. Thus, the correct option for this question is A.

A variable that is purposefully changed in an experiment is an independent variable. Thus, the correct option for this question is B.

A variable that is changed, depending on the change in the independent variable is a dependent variable. Thus, the correct option for this question is A.

What do you mean by Variables?

In experimental science, variables may be defined as a type of factor or information that can be changed during the course of an experiment. It is a type of factor that can be manipulated, controlled for, or measured in an experiment.

In experimental science, there are three types of variables are used. They are as follows:

  • Independent variable: A variable that can be altered during a scientific experiment.
  • Dependent variable: A variable that can be tested or measured during a scientific experiment.
  • Controlled variable: A variable that can be kept constant during a scientific experiment.

A researcher proposes a model to explain how enzyme-substrate interactions determine enzyme specificity. The model is based on the idea that substrate molecules form favorable interactions with the amino acid side chains in an enzyme’s active site. Based on the model, which of the following statements best explains an enzyme’s specificity for a particular substrate molecule?a. A hydrophilic molecule interacts with nonpolar side chains in the enzyme’s active site.b. A hydrophobic molecule interacts with polar side chains in the enzyme’s active site.c. A molecule with positive charges interacts with positively charged side chains in the enzyme’s active site.d. A molecule with negative charges interacts with positively charged side chains in the enzyme’s active site.
