Autotrophic behaviour depends on the ability of the cell to carry out photosynthetic or aerobic respiratory metabolism, which are the only processes able to deliver sufficient energy to maintain carbon fixation. The Calvin cycle is used by bacteria to synthesize organic compounds.
The chloroplast is found only in plant cells. it is the organelle that conducts photosynthesis, but mitochondria are known as the PowerHouse of the cell, and store energy.
Answer:
amino group, fatty acid carboxyl group and R group.
Explanation:
The three parts from which amino acid is formed are the amino group, carboxyle group and R group. These amino acids are the building block of proteins. There are certain foods which contain proteins such as meat and pulses etc. When these foods are eaten, the protein broken down into amino acid with the help of enzymes and absorbed by the cells for building of muscles and other substances in our body.
Answer:
a. Directional selection favors one end of the phenotype distribution, whereas
stabilizing selection favors intermediate over extreme phenotypes
Explanation:
Directional selection is called directional because it favors one phenotype over another, and stabilizing selection finds a balance between phenotypes.
Answer:
The invention of the microscope led to the discovery of the cell by Hooke. While looking at cork, Hooke observed box-shaped structures, which he called “cells” as they reminded him of the cells, or rooms, in monasteries. This discovery led to the development of the classical cell theory.
