Answer: Energy is passed up a food chain or web from lower to higher trophic levels. This loss of energy explains why there are rarely more than four trophic levels in a food chain or web. Sometimes there may be a fifth trophic level, but usually there's not enough energy left to support any additional levels.

Explanation: :) Hope it helps

which statement best describes how the nucleus , the rough endoplasmic reticulum and ribosomes interact during protein synthesis
Flauer [41]

Options found from a different source:

  1. The nucleus gathers amino acids and delivers them to the ribosomes, where they are processed by the rough endoplasmic reticulum to synthesize proteins.
  2. The nucleus provides the genetic information needed to direct the synthesis of proteins by ribosomes that are located on the rough endoplasmic reticulum.
  3. The ribosomes gather amino acids and deliver them to the nucleus, where they are processed by the rough endoplasmic reticulum to synthesize proteins.
  4. The ribosomes provide the genetic information needed to direct the synthesis of proteins by the rough endoplasmic reticulum that is located on the nucleus.

Answer:

2

Explanation:

To synthesise proteins in the cell, the nucleus provides information in the form of DNA. This DNA is transcribed into RNA. The RNA then moves to the cytoplasm, where it is translated at the ribosome, present on the rough endoplasmic reticulum. This occurs through the actions of tRNAs, which bring amino acids to the ribosome.

The sequence that the amino acids are linked together is based on the information from the DNA/RNA.
