What is the definition of the words virus, virion, and viroid. What are the differences between each?

Answers

Answer 1
Answer: Virus is an agent that causes an infectious disease.
Virion is a complete virus fragment.
Viroid is an agent that causes an infection to plants.
Differences:
1. Virus has a protein coat that surrounds the RNA or DNA core but has no semipermeable membrane.
2. Virion has RNA and DNA core coated with protein and external envelops indicating as an extracellular infectious form of a virus.
3. Viroid is kinda similar to a virus. Thus, it only has single strand of RNA and has no protein coat.

After Frida stops exercising, she continues to breathe heavily. What is most likely occurring in her body?A. Heavy breathing during exercise has produced an oxygen surplus in her muscles. This oxygen is being transported to her lungs. This is a result of aerobic respiration.

B. Heavy breathing during exercise has produced a carbon dioxide surplus in her muscles. Lactate is being transported to her liver. This is a result of aerobic respiration.

C.Strenuous exercise has caused her body to be in carbon dioxide debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.

D. Strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.

Answers

The correct answer is option D. Strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.

During exercise, the muscles use the oxygen present there and become deprived of oxygen. Due to less oxygen, the anaerobic respiration occur in the muscles, to overcome this, the heavy breathing takes place. heavy breathing brings the oxygen to the muscles.

During anaerobic respiration, the glucose is broken down into the lactate and the lactate is transferred to the liver for the gluconeogenesis and to maintain the constant supply of the glucose to the muscles.

A simple diagram of Cori cycle (lactic acid cycle) is given below:


Out of the choices given, what is most likely occurring in her body is the strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration. The correct answer is D. 

Most of the matter of the universe exists in which state?

Answers

Answer:

plasma state

Explanation:

Matter in the plasma state has variable volume and shape, but as well as neutral atoms, it contains a significant number of ions and electrons, both of which can move around freely. Plasma is the most common form of visible matter in the universe.

A population of snakes that eat small rodents enters a new habitat. In the new habitat, there are many species of rodents, and their populations are high because there are few natural predators. What will most likely be the effect on the genetic variation of the snake population?

Answers

The Snake population would drastically grow and the rodents would population would get lower and might become endangered in that part of the habitat.

Final answer:

Introduction of snakes to a new habitat with varied rodent species will likely increase genetic variation in the snake population. The forces of natural selection, genetic drift, and possible mutation will drive this genetic diversity.

Explanation:

The introduction of the snake species to a new habitat with many types of rodents, which constitute their prey, will have an impact on the genetic variation of the snake population. This impact will largely be dictated by the forces of natural selection, genetic drift, and potentially mutation.

For instance, certain traits may favor the survival and reproduction of some snakes over others, depending on the exact nature of the predominant rodent species in the new habitat. This is known as directional selection. If the rodent types in the new environment favor the survival of snakes with certain traits, over time, these traits will become more common among the snake population.

Additionally, genetic drift, which refers to random fluctuations in allele frequencies, may also come into play, especially if the initial snake population in this new environment was relatively small. Over time, these factors, along with potential mutations, can contribute to increased genetic variation within the snake population.

4. Which structures are used by the cell for storing and maintaining biological information that will be passed to daughter cells when the cell divides? a. nucleus, chromatin b. nucleolus, ribosome c. vacuole, lysosome d. Golgi apparatus, endoplasmic reticulum

Answers

The answer is A, because the nucleus stores all the genetic information and the chromatin packages DNA to allow cell division and reproduction.
vacuole I think and sorry I have to say this but it is because it says it has to be to 20 to 5000 words long
