Scientific law.
A scientific law describes something in nature and predicts how it will behave without explaining.
This is because before a scientific law has been made, numerous observation has been done under different situations. The scientific law is established when a natural event invariable occur given a set of circumstances.
Answer:
Epistasis
Explanation:
In epistasis, the interaction between genes is inimical, such that one gene masks or interferes with the expression of another. “Epistasis” is a word coined of Greek roots that mean “standing upon.” The alleles that are being masked or silenced are said to be hypostatic to the epistatic alleles that are doing the masking. The cause of the biochemical basis of epistasis is a genetic pathway in which the expression of one gene is dependent on the function of a gene that precedes or follows it in the pathway.
The example of epistasis given is the pigmentation of mice. we were told that "if a mouse has two recessive alleles for coat color, it is always albino no matter what the genotype of other genes involved in coat color"
Let say recessive allele (rr), it is always albino irrespective of other type of other genes, this is true in the stance that epistasis can be reciprocal such that either gene, when present in the dominant (or recessive) form, expresses the same genotype.
Lipids form the bilayer of cell membrane which act as a partially permeable mmbrane of cell to control the substances moving in and out of the cell.
Answer:
eukaryote
Explanation:
That small, dark circle in the center of the cell is the nucleus .Prokaryotes do not have nucleus.
Answer:
Ectotherms warm their bodies by absorbing heat from the surrounding environment, whereas Endotherms produce heat by their metabolic activities. • Ectotherms have large variations in normal body temperatures while endotherms maintain their body temperature in a fairly constant value
