Elements that have atoms with full outer shells of electrons
Are inert
Surface area is an important factor in limiting cell growth because
a. the cell can burst if the membrane becomes too large.
b. materials cannot enter the cell if the surface is too large.
c. the cell may become too large to take in enough food and to remove enough wastes.
d. waste products cannot leave the cell if the cell is too small.
Answer:
c. the cell may become too large to take in enough food and to remove enough wastes.
Explanation:
The exchange of substances with surroundings is done by cells by the process of diffusion. The rate of diffusion of substances requires the presence of a higher surface area than volume. As the cells become larger, their surface area is reduced with respect to the volume. Therefore, larger cells can not support the diffusion of substances in and out as required for its proper functioning. If cells are allowed to grow continuously, they will not be able to intake the requires materials such as food and to release the waste outside.
Answer:
100%
Explanation:
We are given a red flower plant. This means its homozygous dominant (RR). We are given a white flower plant. This means it is homozygous recessive (rr). Each plant will give its allele. The red one will always give R and the white one will always give r. Heterozygous (Rr) plants have pink flowers. So they will all be pink.
Answer:
The answer is false. The correct answer is cerebral aqueduct.
Explanation:
Because the foramen is the area that connects the third ventricle of the brain to the two lateral ventricles.
The canal connecting the third and fourth ventricles is called cerebral aqueduct.
Smaller DNA fragments migrate <u>more quickly</u> and further over a given period of time than larger fragments.
<h3>Gel electrophoresis and DNA fragments</h3>
Gel electrophoresis is a method to separate DNA fragments (or RNA and other macromolecules) based on their size and charge, involving a gel called agarose. The molecules will travel through the gel at different speeds or in different directions, which allows them to be separated from each other.
Because all DNA molecules have the same amount of charge per mass, gel electrophoresis of DNA fragments separates DNA molecules based on size only. Shorter pieces of DNA travel through the pores of the gel more quickly than longer ones do.
