<span>Centrosomes are made of from arrangement of two barrel-shaped clusters of microtubules, called “centrioles,” and a complex of proteins that help additional microtubules to form.</span>
Answer:
An electromagnetic wave
Explanation:
An electromagnetic wave is a transverse wave that can travel across space as well as through matter. When it travels through space, it doesn't lose energy to a medium as a mechanical wave does.
Answer:
Explanation:
In scientific measurement,
Accuracy refers to the closeness of a measured value to a standard or specific value while precision is the level of agreement of a particular measurement with the measured value it is repeated.
It requires energy when a substance must travel against a concentration gradient through the membrane
Answer:
The transport protein-hormone complexes of lipid soluble proteins can not cross the filtration membrane of glomerulus.
Explanation:
Steroid hormones are water-insoluble (hydrophobic) in nature. Since blood has watery medium, the plasma, the lipid-soluble hormones travel in blood through transport proteins. The transport protein-hormone complexes are too large to cross the filtration membrane of glomerulus. The impermeability of the filtration membrane of glomerulus for protein-hormone complexes increases the half-life of lipid-soluble proteins.
