Answer:
C
Explanation:
It is known as lactation. The suckling action of an infant produces prolactin, which leads to milk production; more suckling leads to more prolactin, which in turn leads to more lactation. This is a positive feedback system as the product (milk) produces more suckling and more hormone. When the child is no longer breast feeding, the prolactin drops off and milk production goes down.
I think it is B but if not sorry
Double fertilization-plants with seeds (flowering plants), two male gametes joining with female gametophyte
Gametophyte generation-both (haploid, sexual stage stage-gametophyte, and the diploid stage that produces spores – sporophyte)
Endosperm formed-plants with seed because it is a tissue formed inside the seed which surrounds the embryo and provides nutrition
Mitosis-both (mitosis occurres in spores)
Spores develop into gametophytes-both but, in seedless plants sporophyte produces spores that will develop into a new organism (multicellular gametophyte) using mitosis, while spores of seed plants are produced internally and develop into more complex structures.
Answer:
Option (1).
Explanation:
Enzymes is the biocatalyst that has the ability to increase the rate of a biochemical reaction of the living organism. Enzymes decrease the activation energy of the reaction.
The bacterial cell has the ability to thrive into the human body and may acts as pathogen. The enzymatic activity of the bacterial cell can be increased by increasing the temperature but the temperature should be in the optimum range of the enzyme.
Thus, the correct answer is option (1).
