meiosis a division of germ cells involving 2 fussions of the nucleus and giving rise to four gamates, each possessing half the number of chromosomes of the origional cell.
Answer:
All given options are correct.
Explanation:
Biomolecules may be defined as the organic molecules that are present in the living organism. Four important biomolecules are proteins, carbohydrates, fats and nucleic acids.
The biomolecules are known as macromolecules because they are made of large units of molecule. The mRNA that translates to form a enzymes is macromolecule because RNA is made of large units of nucleotides. Lipid that found in cell membrane are macromolecules because they are made of more than 1000 atoms. Protein that are involved in DNA replication are macromolecules as they have large units of amino acids.
Thus, all the given option are correct.
In some types of research the target population might be as broad as all humans, but in other types of research the target population might be a smaller group such as teenagers, pre-school children or people who misuse drugs.
It is more or less impossible to study every single person in a target population so psychologists select a sample or sub-group of the population that is likely to be representative of the target population we are interested in.
This is important because we want to generalize from the sample to target population. The more representative the sample, the more confident the researcher can be that the results can be generalized to the target population.
One of the problems that can occur when selecting a sample from a target population is sampling bias. Sampling bias refers to situations where the sample does not reflect the characteristics of the target population.
Retinol is the form of vitamin A that causes the greatest concern for toxicity.
Hope this helps!
