A mother's diet before conception can permanently affect how her child's genes function, according to a study published in Nature Communications. A 2003 study found that a female mouse's diet can change her offspring's coat color by permanently modifying DNA methylation.
Answer:
The energy that was not passed on the next tropic level is lost as heat
Explanation:
In an ecosystem flow of energy occur from one tropic level to the next one as the organism of one tropic level eats another organism belongs to the tropic level that is lower from that of previous one.
The 10% of total energy of one tropic level is passed to the next tropic level the rest of the energy is lost as heat in the environment.
Answer:
there are four trophic levels first are producers then primary consumers then secondary consumers then teritary consumers
Explanation:
grass - grasshopper - frog - snake - eagle is a simple food chain
Answer:
Both aerobic and anaerobic respiration.
Explanation:
Glycolysis may be defined as the process of break down of glucose molecules for the formation pf ATP with the help of enzymes and chemical factors. Glycolysis occurs in the cytosol of the organism.
Glycolysis may occur in the presence of organism known as aerobic respiration. The glycolysis can occur in the absence of oxygen as well known as anaerobic respiration. The steps involved up to the formation of pyruvate molecule from the glucose is same in case of aerobic and anaerobic respiration.
Thus, the correct answer is option (c).
Answer:
Concentration gradient
Explanation:
Concentration gradient of the ions across the membrane generates the membrane resting potential.
Concentration gradient means that there is unequal distribution of the ions on different sides of membrane. For example, the concentration of K ions is much higher within the cell then out of the cell. Opposite is with the Na ions. When ions move from the area of their higher concentration to the are with the lower concentration, we say they move down the gradient or diffuse (no energy required). On the other hand, movement of ions against their gradient means that this process requires energy and involves protein pumps.
