Offspring with a 3:1 ratio suggest that both parent that both parent that give rise to this offspring were both heterozygous. Heterozygous individual is someone who has two different allele at a locus whereby by one gene is dominant over the other gene. example of heterozygous parent is a parent Aa pair of alleles. In this pair gene A is dominant over gene a
Answer:
The answer is c. W,X,Z
Explanation:
According to the evolutionary timeline:
- (W) In 1798, Thomas Robert Malthus published an essay, "An Essay on the Principle of Population." Malthus proposed that the current rate of population growth would deplete current resources.

- (Z) In 2003, Wayne State University School of Medicine's Dr. Morris Goodman conducted studies that revealed a 99.4% genetic similarity between human and chimpanzees. This sparked a debate in the scientific community whether to include chimpanzees in the genus, Homo.
- * If Y is part of the choices, it comes after (X).
Protein builds muscle.
So it's gonna be the last one.
Cell membrane fluidity is determined by many things, including the presence of or absence of saturated and or unsaturated fatty acid tails, and because of that the ability of the phospholipids in a cell membrane to tightly pack together or not. I believe though in terms of an additional substance it would have to be cholesterol. These specific lipid molecules are inserted in between the phospholipids preventing phospholipids from tightly packing together thus allowing the cell membrane to have greater fluidity and flexibility.
