Chromosomes are thread-like structures in which DNA is tightly packaged within the nucleus.
Answer:
B. Predation removes slower antelope from the herd.
Explanation:
Natural selection is defined as the differential survival and reproduction of individuals due to differences in the physical characteristics.
A predator-prey relationship results in a very fast-slow dynamical system for rapid predator evolution.
Predation removes slower antelope from the herd and hinders passage of the slow trait to offsprings. The ones who are fast reproduce and give birth to other fast animals.
Answer:
photosynthesis is the way b plants get their energy
Explanation:
The answer to this question would be endocytosis.
Endocytosis a process to bring outside material into cell. The word "endo" itself mean "inside". This material could be source of energy or microbes that need to be killed. It's opposite would be exocytosis. The word "exo" itself mean "outside".
Both of them is pretty similar because they use vesicle to transport the things that need to be moved.
Cytochromes:- They are iron containing hemoproteins that serve many cellular functions including energy production, steroid biosynthesis, and degradation of toxins.
Cytochromes occur in all organisms except a few obligate anaerobes. They are structurally similar among organisms. These are proteins to which one to two tetrapyrrole rings are bound. These tetrapyrroles are very similar to the chromophores of chlorophylls in plants. However, chlorophylls(in plants) contain Mg++ as the central atom in the tetrapyrrole, whereas the cytochromes(in aerobic animals) have an iron atom (Figure).
