Cell division occurs in all living organisms. This is known as mitosis.
The advantages of a larger organisms to subdivide themselves into smaller cells is that as all organisms grow, some of their cells die or get damaged with time and need replacements. So,it divides into smaller cells because when a cell becomes large, it demands more of cell places of its DNA. If the cell grows too large, it will have trouble moving enough nutrients and wastes across the cell membrane. So to grow properly the cells need to be divided.
The best thing to do is this:
the subjects in the experimental group should be given large, daily dose of vitamin C while the control group subjects should be given a daily dose of sugar pills that are disguised as vitamin C.
The research can then observe the differences between the two groups.
The answer is <span>bird droppings that contain seeds from a different location.
</span><span>Gene flow includes a transfer of alleles from one population to another. So imagine a population of plant A on location 1 and another population of plant A on location 2. They cannot interchange their genes. But if birds drop seeds from location 1 and those seeds get to location 2, gene flow may occur.</span>
Answer:
C) are sequence-specific DNA endonucleases
B) degrade foreign DNA that enters a bacterium.
Explanation:
Restriction enzymes are the proteins that cut the DNA at a specific sequence.
<u>Restriction enzymes are also known as restriction endonuclease produced by bacteria that recognizes a specific sequence on DNA and split it by catalyzing the hydrolysis or addition of water molecule. </u>So, Restriction enzymes are sequence-specific DNA endonucleases.
The biological role of restriction enzymes is to restrict the entry of foreign DNA into the bacterium. <u>Restriction enzymes have the ability to restrict the number of bacteriophage strains that affect bacteria.</u>
Hence, the correct options are "C and B"
This indicator is an estimate of the amount of space on the earth that an individual uses in order to survive using existing technology. This space includes the biologically productive land and water area that produces the resources consumed by that individual such as food, water, energy, clothing, and building materials. It also includes the amount of land and water required to assimilate the wastes generated by that person. In other words, the ecological footprint measures a person's demand on the bio-capacity of the Earth.
