The correct answer is:
fixation
Explanation:
Nitrogen fixation is a method by which nitrogen in the Earth's atmosphere is converted into ammonia or other molecules prepared to living organisms. Nitrogen fixation is carried by a diversity of bacteria, both as free-living organisms and in symbiotic association with plants. Because it is the primary source of the nitrogen in the soil, nitrogen that plants need to grow, nitrogen fixation is one of the most critical biochemical processes on Earth
Answer:
Common variable immunodeficiency disease (CVID).
Explanation:
CVID (Common variable immunodeficiency disease) is a medical disease in which the body suffers from the antibody deficiency. The body get easily attacked by the pathogens in this disease.
The chronic infections get repeated in this disease. The B cell deficiency causes the decreased or non functional antibodies in CVID. Genetic mutations are responsible for this disease.
Thus, the answer is Common variable immunodeficiency disease (CVID).
b. kinetic
c. potential
d. trophic
Meristematic tissue and Permanent tissues are two examples of tissues found in the plant.
The bodies of plants, which are multicellular eukaryotic organisms, are made up of organs, tissues, and cells that each perform a highly specialized role.
Meristematic and permanent plant tissue systems exist. Meristematic cells, like animal stem cells, divide and grow the plant. Permanent tissue contains non-dividing plant cells.
Meristem cells quickly specialize and create permanent tissue. These cells have specific functions and cannot divide. Dermal, vascular, and ground tissue distinguish them.
Dermal tissue protects the plant and regulates gas exchange and water absorption. Ground tissue is the site of photosynthesis, provides a matrix for the vascular tissue, supports the stem, and stores water and sugars. Water, minerals, and carbohydrates are carried through vascular tissue.
