Answer:
RNA (tRNA) molecules carry amino acids to the ribosomes during protein .
Answer:
Parents: Yellow (Aarr) and Grey (AaRr)
Explanation:
Given:
allele A = yellow
allele R = black,
Heteroozygous = gray
Genotypes of the parents:
yellow (Aarr) - female
gray (AaRr) - gray
cross between these
Parents: Yellow (Aarr) and Grey (AaRr)
Gametes: (Ar, ar) and (AR, Ar, aR, ar)
F1 (Punnet square)
----|----- AR ------|------- Ar ------|------ aR -----|----- ar
Ar | AARr (gray) | AArr (yellow) | AaRr (gray) | Aarr (yellow)
ar | AaRr (gray) | Aarr (yellow) | aaRr (black) | aarr (cream)
Ratio: 3/8 yellow : 3/8 gray : 1/8 cream : 1/8 black
Answer:
Moving things in and out of the cell is an important role of the plasma membrane. It controls everything that enters and leaves the cell. There are two basic ways that substances can cross the plasma membrane: passive transport, which requires no energy; and active transport, which requires energy.
Chemical reactions are how new forms of matter are made. While nuclear reactions also may produce new matter, nearly all the substances you encounter in daily life are the result of chemical changes. Chemical reactions help us understand the properties of matter
Answer/Explanation:
A: Prophase - Just beginning
B: Metaphase - The two sister chromosomes line up
C: Anaphase - The sister chromosomes separate
D: Telophase - The new spindle has been formed and the cells begin to separate
E: Cytokinesis phase - Ending, where two cells are there instead of one
