In some plants, starch is stored in cell organelles called amyloplasts. Some plant roots and embryos, in the form of seeds and fruit, also serve as storage units for starch. Cells in plant leaves produce starch in the presence of sunlight.
Answer: Option B
The concentration of protein in the postglomerular blood is high comparef with arterial blood because as water passes into the capsule, the concentration of protein in the blood will increase.
Explanation:
Kidneys are bean shaped organs present in veterbrates and it is located in the retroperitoneal space. Kidney filtration involves where blood passes through the afferent arterioles and enters the glomerulus where blood that can be filter like nitrogenous waste and water moves towards the glomerulus and nonfilterable substances such as cells and serum albumins pass out through efferent arterioles. Thee concentration of protein increases from arterial to the post glomerular because some of the water molecules diffuses to the filtrate therefore, reducing water concentration. This lead to increase in concentration of protein because water is not available to diffuse the protein.
Answer: There's no way one species can become another through depuranization, which is a random change.
Explanation:
In cells, environmental (chemical or physical) and metabolic factors can cause DNA damage, which is the molecule that stores genetic material. In these cases, the damage done to the DNA is repaired.
<u>Many of these lesions cause a permanent structural damage to the DNA, which can alter the ability to be transcribed, or can cause mutated genes to be transcribed resulting in another protein.</u> Particularly, depurination is the hydrolytically cleavage of the β-N-glycosidic bond between the purines (adenosine or guanosine) and the carbon of the sugar group found in the DNA. This mutation results in the loss of the purine base and leads to the formation of apurinic site and results and severely disrupts the DNA structure. The most important causes of depurination is the presence of endogenous metabolites inside the cell as a result of various chemical reactions and due to the presence of mutagenic compounds. However, these apurinic sites <u>are usually repaired by portions of the base excision repair (BER) pathway</u>.
There's no way one species can become another through depuranization, which is a random change. Because it is highly unlikely that 5000 mutations are able to accumulate every day without being repaired, and that they are just the right mutations to have the same characteristics as a chimpanzee. <u>If the depurinations are not repaired, the cell will most likely either die or become cancerous.</u>
