Answer:
G, S, G2, M
Explanation:
Cell cycle refers to the orderly events that prepare the cells for cell division and finally divide the parent cells into the daughter cells. The cell cycle consists of two stages: interphase and M phase.
Interphase is the phase wherein cells prepare to enter the M phase. Interphase has three stages: G1, S, and G2.
G1 is the first gap between represents the time between the end of mitosis and the beginning of the S phase. During the G1 phase, normal growth and metabolism take place. G1 phase is followed by the S phase, the synthesis phase, during which DNA replication and synthesis of histone proteins occur.
The cells then enter the G2 or the second gap during which cells synthesize more proteins and prepare to enter the M phase.
M phase is the phase of nuclear division that divides the nucleus of the parent cell into 2 or 4 daughter nuclei (depending on the type of the cell division that the parent cell has entered).
Therefore, the sequence of the stages that the cell will go through is G, S, G2, and M.
Answer: Simple Diffusion Across the Cell (Plasma) Membrane
Explanation:
pretty much the structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down their concentration gradient, by simple diffusion.
HOPE THIS HELPS!!
Answer:
A mutation that causes a single letter change in the DNA sequence can affect your protein structure and function because the sequence of letters in a gene determines the sequence of amino acids in the protein that it encodes. A single letter change in the DNA alters the mRNA which alters the amino acid sequence of the resulting protein and sometimes that can cause serious results if it changes the way a protein works.
Land plants are evolved from green algae.
Green algae called charophytes are coolest relatives of land plants.
It is believed that land plants are the most closely related to green algae, more specifically, a group of green algae referred to as charophyceans. Not only do both land plants and green algae produce chlorophyll a and b, but other evidence suggests that there is a relationship as well.
4 key traits that appear in nearly all land plants but are absent in the charophytes.
-Diploid embryos
- The ability to photosynthesize
-Apical meristem
-Walled spores produced in sporangia.
- Multicellular haploid and diploid generations
-Multicellular gametangia

Your question has been heard loud and clear.
Amino acids is to protein as nucleotides is to nucleic acid.
Thank you
