The role of the excretory system is to rid the body of toxic waste products. Which of these body systems also plays a direct role in removing waste products from the body? A) endocrine B) nervous C) respiratory D) skeletal

Answers

Answer 1
Answer:

Answer:

The correct answer would be C) respiratory system.

Respiratory system is made up of set of organs which help in taking in oxygen and expelling out carbon dioxide from the body.

In humans, it is composed of nose, pharynx, larynx, trachea, bronchi, pair of lungs, and diaphragm.

Alveoli (in lungs) are the site of gaseous exchange where oxygen is exchange with carbon dioxide.

Carbon dioxide is the toxic waste product of cellular respiration. Circulatory system helps in transporting CO₂ from cells to the alveolar site where it is exchanged with oxygen and excreted out as a part of exhaled air.

A scientist agrees with the scientific consensus that dinosaurs have scaly skin. Then he discovers a new fossil that indicates a dinosaur had feathers. The scientist refuses to consider the new evidence because it does not agree with the accepted ideas. The scientist is

Answers

The scientist who refuses to consider new evidence, assuming he or she is not biased or incompetent could do it because if there is a big amount of evidence indicating otherwise, this one new piece of evidence is unlikely and they prefer to wait for more evidence or for analysis of whether this current evidence is not false.

thus this scientist is being skeptical (practicing skepticism) by ignoring this new evidence.

Skepticism is based off of invalid data or an experimental error, but in this case the scientist is being biased.

A retrovirus is?a. is a primitive virus.
b. has a genome made of RNA.
c. has the simplest of all protein coats.
d. was discovered before any other virus.

How is the virus reproduced during the lysogenic cycle?
a. through reproduction of the host cell
b. by using viral enzymes to reproduce viral DNA
c. by using the cell's enzymes to reproduce viral DNA
d. by breaking the cell open and releasing new viruses

Answers

Ans. (b). has a genome made of RNA.

Retroviruses are viruses with RNA molecules as their genome. They insert a copy of their RNA genome into the host cell DNA and change the cell genome. These viruses are generally known as single-stranded positive-sense (+ strand) RNA viruses.

Examples: Human immunodeficiency virus and hepatitis B virus.

Thus, the correct answer is option (b).

Ans. (a). through reproduction of the host cell.

Lysogenic life cycle is a virus reproductive cycle that involves integration of viral nucleic acid into host's genome or formation of a replicon in host's cytoplasm.

The host cells (bacterial cells) remain alive and reproduce normally, so thus, viruses reproduce through the reproduction of host (bacterial cells).

Thus, the correct answer is option (a).

A retrovirus virus has a genome made of RNA. A virus during the lysogenic cyle is the reproduction through the host cell.

Active Enzyme + (1)______ → (2)______ + (3)______a. (1) Product (2) Substrate (3) Active Enzyme

Answers

Answer:

(1)Substrate, (2)Product and (3) active enzymes.

Explanation:

Enzymes are bio catalysts that increases the rate of a biochemical reactions. The enzymes has the ability to work at specific temperature and pH conditions only.

The enzyme binds with the substrate in a biochemical reaction and decreases the activation energy of the reaction. After that the substrate is converted into the product and active enzyme leaves the reaction.

Thus, the correct answer is (1)Substrate, (2)Product and (3) active enzymes.
the answer is 2 1 3 i think
