Answer:
A. FALSE
B. TRUE
C. FALSE
D. FALSE
Explanation:
A. DNA molecules consist of two strands of a helical chain of nucleotides, which are the monomer subunits of DNA.
B. Nucleotide subunits that make up a DNA strand are polar due to the presence of the phosphate group per subunit.
C. There are only four different nucleotides in a DNA strand. The nucleotides are different from each other based on the four nitrogen bases. These are adenine, thymine, cytosine, and guanine.
D. Hydrogen bonds are present between the nitrogen bases of nucleotides from anti-parallel DNA strands. Phosphodiester bonds, on the other hand are present between nucleotides of an individual DNA strand thus holding one DNA molecule together.
Answer:
In a hypotonic solution, the solute concentration is lower than inside the cell. ... Depending on the amount of water that enters, the cell may look enlarged or bloated. If the water continues to move into the cell, it can stretch the cell membrane to the point the cell bursts (lyses) and dies.
Answer:
parasitism
mutualism
commensalism
Explanation:
Commensalism is defined as a relationship between two living organism in which one organism get benefits and the other organism neither benefit nor harm.
Herbivory is defined as the relationship between organisms and plants in which organisms consume plant material.
Mutualism is defined as the relationship between two living organism in which both organisms benefit each other.
Parasitism is defined as the relationship between two living organism in which one organism get benefits and the other organisms get harmed.
So, a flea and dog are an example of parasitism, certain bacteria live in the digestive tract of humans is an example of mutualism, and relationship between cattle egrets and an elephant is an example of commensalism.
Hence, the correct answer is:
parasitism
mutualism
commensalism
