Answer:
Option (4)
Explanation:
Carbon forms the basin element for the existence of life. It is present in the atmosphere in the form of CO₂, which is one of the major green house gas. It plays an important role in the carbon cycle.
The increase in the concentration of carbon in the atmosphere can lead to the global rise in the temperature. It can lead to global warming. The amount of carbon in the atmosphere has been rising continuously, right after the industrial revolution.
The carbon is mainly emitted from the heavy industries and factories, vehicles, burning up of fossil fuels. It also increased due to the increasing absorption of solar radiation.
This emission of carbon if not controlled by the humans, then the concentration of carbon in the atmosphere will abruptly increase after some decades.
Thus, the correct answer is option (4).
What is differentiation in multicellular organisms?
A multicellular organism undergoes numerous rounds of differentiation as it develops from a straightforward zygote to a complex system of tissues and cell types.
What is an example of cell differentiation?
The transformation of a single-celled zygote into a multicellular embryo and then into the complex multisystem of several cell types that is a fetus is an illustration of cell differentiation.
What is the process of differentiation?
- Differentiation is the process by which unspecialized cells become specialized to carry out distinct functions.
- Stem Cells. A stem cell is an unspecialized cell that can divide without limit as needed and can, under specific conditions, differentiate into specialized cells.

Passive transport is a movement ofbiochemicals and other atomic or molecularsubstances across cell membranes without need of energy input. Unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy. The rate of passive transport depends on thepermeability of the cell membrane, which, in turn, depends on the organization and characteristics of the membrane lipids andproteins. The four main kinds of passive transport are simple diffusion, facilitated diffusion, filtration and osmosis.
Answer:
Generalists would be most abundant, because the resources available would be constantly changing.
Explanation:
A generalist species is a species that can live and survive in different types of environments, and also have different range of diets it can feed on. Ominivores such as raccoon is an example of a generalist species which has varied diets and can survive in different environmental conditions, enabling it to maintain its population from season to season.
Organisms that would inhabit a biome that experiences large seasonal fluctuations in both temperature and precipitation patterns is best characterized by the abundance of generalist species, be because the resources available would be constantly changing.
