The sun isn’t out so photosynthesis cant happen
One thing that separates us from the other animal classifications is that we have hair, everywhere! :D The next major difference is the fact that mammals don't lay egg's, we give birth to live creatures. Those are the 2 biggest things that distinguish us from them.
Hope I helped. :)
Answer: A(secondary active transport)
Explanation:
Secondary active transport, is transport of molecules across the cell membrane which utilizes energy created by co-transporter pumping of ions across the membrane in an electrochemical gradient.
The reabsorption of glucose from the proximal tubule occurs via secondary active transport.
The reabsorbption of glucose does not depend the concentration gradient but on the reabsorption of sodium a co-transporter.
ATP is used in the movements of Na+/K+. Energy is also produced from sodium electrochemical gradient concentration and it is enough energy to transport glucose across the membrane into the epithelial cells.
Answer:
Homologous genes that are highly conserved.
Explanation:
Phylogenetic trees are diagrams that represent evolutionary relationship between organisms.
It is set to represent the hypothesis that a set of species evolved fro the same ancestor.
Anatomical similarities are considered in the construction of the trees.
However , two organisms can be placed in the same tree by comparing their genes.
If the two eukaryotes have genes that are highly conserved that similar.
