Why is it necessary to seperate oxygenated and deoxygenated blood in mamals and birds? explain​

Biology
1 answer:
yKpoI14uk [10]3 years ago
7 0

Answer:

It is necessary to separate oxygenated and deoxygenated blood separate in mammals and birds to maintain their body temperature. Also, if they both are mixed, the blood will get impure and it would be difficult for the heart to supply impure blood. We also can't live with impure blood so we most probably will die.

Macrophage cells undergo a process called phagocytosis in which material is brought into a cell in the form of membrane vesicles
Naddik [55]

The correct answer is: A. minus end; dynein

Microtubules are cytoskeletal fibers that have an important role in the intracellular transport (movement of vesicles within the cell) and in the mitotic spindle during mitosis. The plus end of the microtubules extend through the periphery of the cells while the minus ends are anchored within the centrosome.

Necessary proteins for the vesicle’s movement are motor proteins:

• kinesin  which is positive end directed

•  dynein which is negative end directed

So, beside vesicles these proteins are also involved in organelles’ transport in opposite directions through the cytoplasm.

The electron transport chain is named for Select one: a. the removal of unnecessary electrons from the cell b. the conversion of
Colt1911 [192]

Answer:

The correct answer is e. the passage of electrons from one energy-generating carrier to another

Explanation:

The electron transport chain is a series of proteins and organic molecules found in the inner membrane of the mitochondria. Electrons pass from one member of the transport chain to the next in a series of redox reactions. The energy released in these reactions is captured as a proton gradient, which in turn is used to form ATP in a process called chemosmosis.

These transport molecules, in the inner mitochondrial membrane, are reduced and oxidized, accepting electrons and transferring them to the next molecule, electrons descending from high energy levels to lower ones, that is, from one energy-generating carrier to another. When lowering to other levels, energy is released that will be used in the synthesis of ATP by oxidative phosphorylation.
