the prime mover of inspiration is the blank during normal quiet breathing expiration is a passive process as this muscle relaxes into its original dome shape. provide conditions when expiration becomes an active process or forced. explain

Answers

Answer 1

Answer:

The prime agonist of inspiration is the diaphragm muscle.

The conditions when expiration becomes an active process is : Emphysema, Pneumonia, Bronchitis.

-Expiration is the passive process as there is elastic recoil of lungs following inspiration without contraction of any muscles.

-The elastic fibers in alveoli are damages or filled with mucus and fluid in the disease such as conditions such as emphysema or pneumonia.

-Elastic recoil of lungs.

-Hence, muscle contraction is required to forcefully exhale the air from lungs. Internal intercostal muscles contract to pull the ribs downward and remove air from the lungs.

Which of the following processes
describes a cell undergoing exocytosis?
A. cell eating
B. diffusion
C. removing water and waste
D. moving molecules along a concentration gradient

Answers

Answer:

C. removing water and waste

Explanation:

Exocytosis occurs when a cell produces substances for export, such as a protein, or when the cell is getting rid of a waste product or a toxin.

Hope this helps

Answer:

[tex]\boxed {\boxed {\sf C. \ Removing \ water \ and \ waste}}[/tex]

Explanation:

We are asked to find a description for a cell undergoing exocytosis. First, let's define the process.

Exocytosis is a type of active transport, so ATP or energy is required to initiate and complete the process.

This process moves substances from the inside of a cell to the outside. Molecules are packaged into vesicles. The vesicle moves to the cell membrane and attaches. The vesicle fuses with the membrane and the molecules inside the vesicle are released.

Essentially, substances are removed from the cell. This is especially useful because it can rid the cell of any waste or excess water. Therefore, the correct answer is choice C.

Answer:

发发发 发斯蒂芬

Explanation:

Presence of capsule. Therefore, option (B) is correct.

What was Griffith's experiment?

Griffith's experiment of transformation is a landmark experiment in microbiology conducted in 1928 by British bacteriologist Frederick Griffith. The experiment aimed to determine the nature of the "transforming principle" responsible for transferring genetic material between bacteria.

Griffith used two strains of Streptococcus pneumoniae, one that was virulent and had a polysaccharide capsule (S strain) and another that was non-virulent and lacked the capsule (R strain). He found that when he injected mice with the heat-killed S strain and live R strain, the mice died, and live S strain was found in their blood. This suggested that the R strain had been transformed into the S strain, and the genetic material was responsible for the transformation.

Griffith's experiment provided the first evidence of bacterial transformation and paved the way for future research on the molecular basis of genetics.

Describe the purpose of mitosis.
2. Describe what is happening in each stage and what each stage looks like:
Prophase
Prometaphase
Metaphase
Anaphase
Telophase
Cytokinesis

Answers

Answer:

To acquire growth and to replace worn out and defected cells.

Explanation:

The main purpose of mitosis is to acquire growth and to replace worn out and defected cells.

In prophase, the chromatin condenses which is present in the nucleus of the cell.

Prometaphase is the stage where the nuclear membrane breaks apart into numerous "membrane vesicles".

Metaphase is the phase where all the genetic material is condensing into chromosomes.

Anaphase is the stage in which chromosomes are pulled by the spindle fibers to opposite poles of the cell.

In Telophase, the cell is nearly dividing, and it starts to re-establish its normal structures as cytokinesis (division of the cell contents) takes place.

Cytokinesis is the process which divides the cytoplasm of a parental cell into two daughter cells.

Answers

All the metabolic wastes are excreted in a form of water solutes through the excretory organs (nephridia, Malpighian tubules, kidneys), with the exception of CO2, which is excreted together with the water vapor throughout the lungs. The elimination of these compounds enables the chemical homeostasis of the organism.

Which of the following factors would LIMIT carrying capacity?
A. Far from factories or roads
B. A large nearby river
C. Abundant food
D. A small space to live in

Answers

Answer:

D. A small space to live in

Explanation:

Having a small space to live in would directly limit carrying capacity.

Since there is a small space, only a few organisms would be able to live in that space.

This means that carrying capacity is limited, because the space does not have enough room to sustain more people.

So, the correct answer is D. A small space to live in

You learned in the previous lesson that T cells require two independent signals to become activated. When T cells are activated, they acquire effector functions and begin to proliferate. This two-signal mechanism prevents the expansion of self-reactive effector T cells. Similarly, B cell receptor signaling alone is not sufficient to activate B cells. B cells require assistance from helper T cells to become activated by monovalent protein antigens and gain certain immune functions. What changes do you suspect will occur to B cells when they are activated by protein antigen and receive T cell help? (select all that apply)
a) They will generate memory cells that can respond to a subsequent exposure to antigen.
b) Their immunoglobulin genes will be mutated in a way that alters antigen affinity.
c) The isotype of their immunoglobulin (Ig) genes will change.
d) They will proliferate and expand.
e) They will secrete antibodies.

Answer:

a. They will generate memory cells that can respond to subsequent exposure to antigen.

d. They will proliferate and expand

e. They will secrete anti bodies

Explanation:

B cells are type of white blood cells who belong to lymphocyte subtype. They are activated by binding of antigen to receptors on cells surface, against which they initiate and antibody response. Some of these cell proliferate and divide while other become long lived memory cells that respond subsequent exposure to antigen at later stage.

Two organisms, AABBCCDDEE and aabbccddee, are mated to produce an F1 that is self-fertilized. If all of these genes are on the same chromosome, and there is no recombination, how many different genotypes will occur in the F2

Answers

Answer:

2 genotypes: AABBCCDDEE; aabbccddee

Explanation:

The law of segregation (also called Mendel's First Law) describes how genes on different chromosomes segregate into gametes independently of each other. Moreover, recombination (also known as crossing over) is the interchange of genetic material between non-sister chromatids during meiosis. In this case, the five genes are on the same chromosome (i.e., they are linked together and do not segregate) and there is no recombination, thereby they are inherited as a haplotype block to the next generation:

- Genotypes parental (P) lines: AABBCCDDEE; aabbccddee

- Cross P1: ABCDE X abcde

- Genotype F1: AaBbCcDdEe (100%)

- Gametes F1: ABCDE; abcde

- Genotypes F2: AABBCCDDEE; aabbccddee (ratio 1:1)

An unknown solution has a pH of 7.1. Which of these chemicals is likely to increase the pH the most when added to the solution?

HF

KOH

NH3

HNO3

Answers

Answer:

It is most likely KOH

Explanation:

NH3 is classified as a weak base so I'd suspect that to be incorrect although it does have a higher pH

The chemical that is likely to increase the pH the most when added to the solution is KOH. The correct option is B.

What is pH?

pH is the scale for the measurement of acidity and the basicity of any solution. pH is a scale from 1 to 14. The lowest pH will be highly acidic and the highest pH will be the highest basic.

The lowest the pH, it will donate the highest hydronium ions, and with the highest pH, it will dissociate completely into the solution. KOH dissociates completely into ions.

KOH or potassium hydroxide is a strong base. When the base is added to a solution, it increases its basicity. So it will increase the pH of the solution. All others are acids that will lower the pH of the solution.

Thus, the correct option is B. KOH.
