Which of the following conditions would lead to a small population size?a.) a low birth to death ratio

b.) a high birth to death ratio

c.) immigration

d.) large number of resources

Answers

Answer 1
Answer:

The condition that would lead to a small population size is a low birth-to-death ratio. Thus, the correct option for this question is A.

What is the Population size?

According to genetics and population ecology, Population size may be defined as the number of individual organisms in a population. Population size may directly depend on evolutionary forces like genetic drift, mutation, etc.

A low birth-to-death ratio means the number of birth is usually smaller than that of the death in any population. So, the size of the population gradually decreases.

While a high birth-to-death ratio means the number of birth is usually larger than that of the death in any population. So, the size of the population gradually increases. Immigration and a large number of resources are also the conditions that lead to the large population size.

Therefore, a low birth-to-death ratio is a condition that would lead to small population size. Thus, the correct option for this question is A.

The absorption of alcohol can be slowed down by eating, but only __________ can reduce the BAL level. Sleep Water Coffee Time

Answers

The answer is Coffee. Fatty foods will back off liquor retention fundamentally, as they adequately shape a covering that it can't without much of a stretch go through.However, sustenance in the stomach will likewise significantly accelerate the rate of gastric purging. This implies the liquor comes all the more rapidly into contact with the dividers of the upper segment of the small digestive system [the duodenum], through which it is retained significantly more effectively into the blood than it would be however the dividers of the stomach.
When alcohol reaches the blood, nothing can be done to lower down the BAL levels. But, the absorption of alcohol can be reduced by consumption of the foods rich in starch, which will absorb alcohol from the blood, althogh only little. Rest of the acohol wil be cleared by the liver, after some time.

What takes place when you inhale and exhale ?

Answers

When you inhale and exhale, you actually breathe. When you inhale, your intercostal muscles between ribs and diaphragm contract. This increases the space in chest cavity so your lungs can expand and the air enters the lungs. When you exhale, intercostal muscles and diaphragm relax reducing the space in the chest which leads to removing the air from the lungs.

Which of the following is not considered a fossil fuel?a. Coal
b. Crude oil
c. Natural gas
d. Nuclear energy

Answers

Nuclear energy is not considered as a fossil fuel. Thus, option D is current.

Nuclear energy is not considered a fossil fuel. Fossil fuels are formed from the remains of ancient plants and animals that were buried and subjected to high pressure and temperature over millions of years. Coal, crude oil, and natural gas are examples of fossil fuels.

On the other hand, nuclear energy is generated through the process of nuclear fission, where the nucleus of an atom is split, releasing a large amount of energy. It is not derived from organic matter and does not involve the burning of fossil fuels. Instead, it relies on the utilization of radioactive materials, such as uranium or plutonium, to produce heat and generate electricity.

Ciprofloxacin (cipro) is an antibiotic that inhibits bacterial dna replication. it enters cells by diffusion. many cells resist the action of cipro by expressing a membrane protein that pumps the antibiotic out the cell. what does the cipro-resistance protein have in common with porins?

Answers

The porins are the membrane proteins, which allows the transfer of the molecules. It is a transport protein. The cipro-resistance protein is also a transport protein. Both the porins and the cipro resistance proteins are membrane transport protein. The presence of the cipro-resistance protein does not allow the ciproflaxin drug molecule to cross through the normal protein, as a result it causes resistance.
