Four factors that affect population growth:

1. Birth Rate: The number of a baby being born in the population

2. Death/mortality rate: The number of death happening in the population

3. Immigration: The number of people entering the population

4. Emigration: The number of people leaving the population

<h3>Further explanation </h3>

A population is a group of individuals of the same species that live in a particular area or the number of people living in the same area, for example, a city population means the number of people living in that city.

Population growth is the change in a population over time. It can be increasing or decreasing, depend on those factors above.

The population's growth rate increase when the birth rate is higher than the death rate, or the emigration is lower than the immigration. When the death rate is higher than the birth rate or the emigration rate higher than immigration rate the population's growth is decreased. The population growth is a result of a combination of natural increase and migration flows.

There are four major factors that affect population growth:

<span>
Birth rate<span>: The number of births per 1000 people in a year. This has a positive effect on population growth. </span>This makes sense, as people being born adds to the population.</span>

Death rate: The number of deaths per 1000 people. This has a negative effect on population growth. People dying lowers the total population.

Immigration<span>: The number of people entering the population. This has a positive effect on population growth. People entering the population increases it.</span>

Emigration<span>: The number of people leaving the population. This has a negative effect on population growth. People leaving the population decreases it. </span>

A heart cell was taken from a rat and placed in Flask A, which contained a nutrient-rich culture medium. A kidney cell was taken

BabaBlast [244]

A heart cell taken from a rat and placed in Flask A with a nutrient-rich culture medium produced heart cells after 24 hours.

A kidney cell taken from the same rate placed in Flask B with a similar nutrient-rich culture medium produced kidney cells after 24 hours.

A trait, such as height, has high heritability because much of the variation between individuals is the result of genetic variat

Len [333]

This is because the traits like height, are influenced by environmental conditions around the individual. For example, there are two children born to same mother. But one is given best facilities, nutrition and care, whereas other one is brought up by a poor family, which hardly get good food to eat. His condition is much worse than the first case. In such a situation, the former child will grow up healthy and fit, and will have more height than the later one. Although, both got genes from same parent, but the environmental conditions influenced the expression of those genes differently.

Cellular processes are carried out by many different types of molecules, mostly proteins. The function of each protein molecule

Vitek1552 [10]

Answer:

option A

Explanation:

The protein specific sequence also known as the primary sequence is determined by the sequence of its amino acids linked together by peptide bonds. The sequences of amino acids determine the proteins that will eventually be synthesized. This proteins becomes functional when correct folding pattern/ native conformation of the protein occurs which determines the shape of the proteins. peptide bonds hold the amino acid sequences together, hydrogen bonds involving components of the peptide bonds allow for the existence of the secondary structure either the alpha helix or the beta pleated sheets and then disulphide bonds and other type of bonds helps in the folding of the protein to become a functional protein.
