A deficiency in thiamine (TPP) will directly decrease the activity of which of the following enzymes? a. Pyruvate carboxylase b.

Blababa [14]

Answer:

d. Transketolase

Explanation:

Transketolase utilize thiamine diphosphate (ThDP) as cofactor has reduced activity during the thiamine deficiency and results in the tissue damage. <u>The levels of steady-state mRNA of transketolase in human lymphoblasts, fibroblasts and neuroblastoma cells are found to be lower in the thiamine-deficient cultures. </u>

How can telescopes aid visualizing the electromagnetic spectrum?what is the “best place” for telescopes “to detect most radiation” and why?

$\huge \bold \green{answer} \\$

Astronomers use telescopes that detect different parts of the electromagnetic spectrum. Each type of telescope can only detect one part of the electromagnetic spectrum. There are radio telescopes, infrared telescopes, optical (visible light) telescopes and so on.

The best place to detect most radiation is above the blocking atmosphere, so some telescopes are put in orbit around the Earth. Even visible light is distorted by the atmosphere, so clearer pictures can be got from orbiting telescopes.

Answer:

Blood capillaries

Explanation:

The walls of capillaries are just one cell thick. Capillaries therefore allow the exchange of molecules between the blood and the body's cells - molecules can diffuse across their walls. This exchange of molecules is not possible across the walls of other types of blood vessel.
