The RBC are produced in the bone marrow through a process that takes 7 days called erythropoiesis. This is where the stem cells of hemopoietic differentiate into reticulocytes. Iron, Vit B12 and folic are necessary for hemoglobin synthesis. The reticulocytes become functional RBC after 24 hours in the bloodstream.
After 120 days the RBC are destroyed in the spleen through a process called eryptosis. The heme part is broken down into biliverdin and iron. Iron is recycled by the transferrin while biliverdin is excreted through bile.

geniusboy [140]

Answer: C. Preying

Explanation:

A non-native species is the species which is introduced to a new ecosystem. This species is introduced intentionally or accidentally to a new ecosystem by human beings or they may enter to the ecosystem by their own.

A non-native species can be invasive which means it can compete with the native species for resources like shelter, food and mates.

According to the given situation, the Gila trouts being the native species has been affected by the non-native Rainbow trout. This may be because of the fact that non-native species can be invasive for the native species. As the species is used as mate by the non-native species and they may become the prey of non-native species. This has resulted in the extinction of the species of Gila trouts.

Nataly [62]

Answer:

The correct answer is - photosystem II; ATP; water; oxygen

Explanation:

The photosynthesis process involves two different cycles known as the light reaction and the dark reaction. In light reaction there are two photosystems; photosystem I and photosystem II.

During light reaction, there are several pigments such as chlorophyll a and other pigments present in photosystem II that trap the light and transfer excited electrons through ETC to produce ATP which is a form of energy used by cells.

A water molecule takes place of the excited electron that is transferred and releases oxygen as waste or byproduct in this reaction.
