The statement "The correct way to calculate population size is by dividing the total population by the land area." is true. The correct option is A.
<h3>What is the population?</h3>
The entire number of species in a given area makes up the population. Surveys of various places are conducted to determine the population. By dividing the total population by the fraction of each individual, the population size can be determined.
There are various techniques for population counting. Cohort analysis, aerial counts, etc., are some of these techniques.
Thus, the statement is true. The correct option is A.

Answer:
monomers of MONOSACCHARIDES
Explanation:
Polysaccharides are large molecules formed from chains of POLYMERS linked together by glyosidic bonds. <u>MONOMERS are small sub units that formed polymers, they are therefore the building block of a polysaccharides. The monomers of polysaccharides are called monosaccharid</u>es (1 sugar molecule.) when two of these are joined together they formed disaccharides (two sugars.)
Polysaccharides are fromed by joining together condensation, (loss of water molecules,) of mutiple monosaccharides units and the reversal of this to add water molecules to sepate them to monosaccharies is sugar Hydrolysis.
Example of polysaccharides are starch, glycogen cellulose
Example of monosaccharides are glucose, galactose.
Disaccharides are common table sugar, sucrose, maltose, lactose
Answer:
True
Explanation:
Reproduction is one of the essential characteristics of all living beings. However, if they reproduce to their full capability, the number of offspring would be higher than the available resource. Due to this reason there is always shortage of resources and hence competition arises among the species.
The fit species survive among all the competing species while the remaining weak species die. As Darwin also said that species have the ability to reproduce uncontrollably therefore, competition among the species for survival is a mode of population regulation
Hence, the given statement is true
That should be the cell membrane. The cell membrane acts as a filter in and out.
