What is Malthusian theory ?

In his essay "An Essay on the Principle of Population" from 1798, English economist and demographer Thomas Malthus predicted that population increase would eventually outpace the supply of resources, particularly food. He stated that although the production of resources and food only develops arithmetically (linearly), the growth of the human population is geometric (exponentially).

Therefore, He anticipated that unregulated population increase would result in resource shortages and overpopulation, which would cause poverty, starvation, and other societal problems. The "Malthusian theory" is the name given to Malthus' population theory, which has been the subject of dispute and discussion ever since.

Therefore, (Option B) is correct.

Describe how physical property, such mass or texture, can change without causing a change in the substance?

Answers

Mass and texture are physical properties of matter which doesn’t affect their elemental conditions at the atomic level, on the contrary, chemical change does. Observe toxification –oxidation- rusting that wears out the metal forming a new substance. Mass, in one hand is only the addition of matter in a particular object. Texture in another, is only the smoothness or roughness of the object in the basis of its components. In application to answer the inquiry. Subject may change both mass and texture without affecting the entire composition of the atoms of the object. For example a bed sheet was piled with tons of pillows are bed sheets all over, some sheets were a bit soft and some weren’t hence, the mass is also greater compared to one sheet alone. No chemical change here. Just the extrinsic properties.

Explanation:

A pea plant is heterozygous for height (Tt). Which allele will be carried by a pollen grain produced by the plant?  A.T only  B.t only  C.T and t  D.T or t

Answers

It depends on the dominancy of the genes. If T is dominant, then the plant will grow taller and if t is dominant, then the plant will grow as dwarf. So, I think the correct option is C. T or t.

Answer:

The correct answer would be option D. T or t.

It can be explained with the help of the law of segregation.

This law states that alleles for each gene are randomly segregated into the gametes such that each gamete carries only a single copy of each allele.

Hence, if a parent cell contains T and t alleles so, T and t will randomly segregate into pollen grains (gametes).

It will result in the formation of two types of pollen grains or gametes each having an equal chance of inheriting T as well as t.

So, we can say that pollen grain produced by the plant (Tt) can carry either T or t in it.
