The Sun is the primary source of energy for ecosystems. The Sun emits______ . When an organism obtains nutrients by feeding on o
Burka [1]

This scientific law is called as Law of conservation of energy.

Sun is the primary source of energy .Energy once produced by the sun is then utilized by the organisms at various tropic levels. The energy is transferred from one organism to another. Energy is neither created nor destroyed. This is called as law of conservation of energy. Plants uses sunlight and make food   and the energy is then transferred to organisms eating it. When the organism dies the energy is released into the environment. This cycle continues and the the law of conservation of energy is maintained.

Would the correct protein be made if TRNA did not work correctly?
galina1969 [7]

Answer:

The short answers are Yes, it's random, and Yes, it "waits" for some time.

Different tRNA's just float around in the cytoplasma, and diffuse more or less freely around. When one happens to bump into the ribosome, at the right spot, right orientation, and of course which has an anticodon matching the codon in frame of the mRNA being translated, it gets bound and takes part in the synthesis step that adds the amino acid to the protein that is being synthesized.

The concentration of the various species of tRNA is such that translation occurs in a steady fashion, but there is always some waiting involved for a suitable tRNA to be bound. In that waiting time, the ribosome and mRNA stay aligned - that's because the energy that is required to move the to the next position is delivered as part of the same chemical reaction that transfers the amino acid from the tRNA to the protein that is being synthesized.

I'm not entirely sure what happens if there is significant depletion of a particular species of tRNA, but I think it's likely the ribosome / RNA complex can disassemble spontaneously. But spontaneous disassembly can't be something that occurs very easily after translation was initiated, since we would end up with lots of partial proteins which I expect would be lethal very soon.

(Can't know for sure though, but it would be very hard to set up an experiment to measure just what will happen and even if you got a measurement it would be hard to figure out how it applies to normal, living cells. I can't imagine tRNA depletion occurs in normal, healthy living cells.)

Which of the following statements about hormones are correct? Hormones can be peptides, steroids, or amino acid derivatives. Hor
daser333 [38]

Answer:

Statements 1, 2 and 4 are correct:

"Hormones can be peptides, steroids, or amino acid derivatives."

"Hormones can stimulate the synthesis of target proteins through the activation of specific genes."  

"Hormones can increase the cellular uptake of metabolites."

Explanation:

Hormones are basically proteins that are released under particular conditions to bring about a certain response in the body. They can activate genes and even change how cells respond to metabolites, for instance, insulin and glucagon are two hormones that regulate the level of sugar in the blood. Another example is the hormone adrenaline, which is released in the 'flight-or-fight' response to prepare the body in taking action.

Hope that answers the question, have a great day!
