Answer: 30. D. Cell
31. A. Tissue
32. D. Biome
33. A. Population
34. D. Condensation
35. B. Precipitation
Explanation:
30. A cell is a largest component of life among the options given. As it includes within it molecule, and organelles required for the functioning and metabolism of cell.
31. A tissue is the smallest component of life. It is made up of group of cells. The cells combine together in tissue to perform a specialized function in organisms.
32. Biome is the largest ecological group which includes diversity of living organisms interacting with the physical environment. The biome is characterised by abiotic factors like climate, temperature, geography, and soil and also by the biotic factors such as flora and fauna.
33. Population is the smallest group which includes the members belonging to the same species living in the same location or region. These members are capable of inbreeding among themselves and producing viable offsprings.
34. Condensation is a process in which the water vapors being in high temperature cools down in the sky to form clouds. It is the part of water cycle.
35. Precipitation is the part of the water cycle. In this the clouds formed after the condensation process, due to increase in amount of water vapors in them the water falls off under the effect of gravity. The precipitation is in the form of sleet, snow, hail, drizzle and rain.

Answer: Spermatogenesis begins at birth and continues throughout a man's life.
The process in which
haploid spermatozoa develop from germ cells in the seminiferous tubules of the
testis is known as Spermatogenesis. Thus, the process of spermatogenesis start
with mitotic division of the stem cells that is located close to the basement
membrane of the tubules. However, a mature male gametes known as sperm but it
is commonly known as spermatozoa.
Answer:
<h2>Its true!!</h2>
Explanation:
Actually the haemoglobin molecule consists of 2 parts, the haem which is a prosthetic group and the other globin which is a protein. So the haemoglobin as is a protein so, is arranged in quaternary structure of protein which contains 4 subunits. The subunits depend upon the organism whose haemoglobin is being talked about. So the normal haemoglobin found in red blood cells contains 2 alpha subunits + 2 beta subunits. At the centre of each subunit there is the haem part attached. To the centre of haem the Fe3+ ion are present which actually attaches to 1 Oxygen molecule. So as 4 subunits are present and each subunit has 1 Fe3+ ion, so total 4 Oxygen molecules can bind to the 1 Hb molecule!!
