Answer:
Energy enters the ecosystem via sunlight as solar energy
Explanation:
when the solor energy comes down it goes to the grass when the animals eat it they have consumed that i put a picture below if that helps
The young tomato plant doesn't have enough energy to pull more leaves out after its already grown a stem, very hot temperatures will stunt the growth of the tomato plant because of this.
Answer:
Villus, plural villi, in anatomy any of the small, slender, vascular projections that increase the surface area of a membrane. ... The villi of the small intestine project into the intestinal cavity, greatly increasing the surface area for food absorption and adding digestive secretions.
Answer: Thrombus Formation
Explanation:
Atherosclerosis is a chronic, progressive disease in which the plaques starts building in the walls of artery. These plaques are the deposition of the cholesterol and other lipids, calcium and inflammatory cells known as macrophages.
Once these substances starts depositing in the artery it can lead to thrombus formation which is not cured by itself.
The Atherosclerosis is the predisposes to the thrombus formation which can cause myocardial ischemia.
Answer:
(a) crossing over: Meiosis I, Recombination
(b) chromatids separate at their centromeres and migrate to opposite poles: Meiosis II, Anaphase II
(c) chromosomes become aligned in pairs at the equator: Meiosis II, Metaphase II
Explanation:
Homologous recombination is a type of genetic recombination that occurs during meiosis (formation of ovum and sperm cells). The paired chromosomes of the male and female parents are aligned so that similar DNA sequences intersect. This crossing over produces an exchange of genetic material, which is an important cause of the genetic variability observed in the offspring.
Meiosis II: Anaphase II. The centromeres separate and the daughter chromatids - now individual chromosomes - move to the opposite poles of the cell. The centromeres separate, and the two chromatids of each chromosome move toward the opposite poles in the spindle.
Meiosis II: Metaphase II. Chromosomes are accommodated in the equatorial plate of metaphase, similar to what happens in mitosis. They are attached to the already fully formed meiotic spindle. Each chromosome is aligned in the equatorial plate of the metaphase, as it happens in mitosis.
