A Protein Pump :- Protein pumps use energy from hydrolysis of ATP to move ions or large molecules across cell membrane.
Purpose of a Protein Pump :- In a Protein Pump the proteins help in active transport of molecules. Example, Membrane proteins are very specific and help in active transport. These proteins are positioned to cross the membrane so one part on the inside of the cell and one part is on the outside of the cell. Only when they cross the bilayer(cell membrane) they are able to move molecules and ions in and out of the cell.
Need for a Protein pump to work :- In active transport, A protein pump changes its shape when allows movement of molecules and therefore requires energy in the form of ATP. They use the energy of ATP hydrolysis to move ions or small molecules across a membrane.
Population control may involve culling, translocation, or manipulation of the reproductive capability. The growth of a population may be limited by environmental factors such as food supply or predation.
Answer:
There are three types of survivorships:
Type 1: Type 1 survivorship includes organisms which have high chances of surviving through the early and middle stages of life. Their population tends to decline in the old age. For example, humans
Type 2: Type 2 survivorship contains organisms which have a constant mortality rate. The chances of an individual to die are independent of their age.For example, birds
Type 3: Type 3 survivorship includes organisms which have a rapid death rate during the early stages and only a few organisms survive till adulthood.
The best answer is that Genes code for proteins!
Chromosomes is where the genes are located (humans have a lot less chromosomes than genes)
Enzymes are chemical substances that participate in the creation of proteins.
RNA is another molecule which is important for making of proteins, but it is more fitting to say that the Genes are the ones coding for proteins. (RNA participates in the coding and decoding of genes)
Answer:
A-all of the answers are correct
Explanation:
In DNA replication, the strands come apart and creat a "new copy" of the original strand.
