A pond has fish, crawfish, oysters, lilies, and algae. All these species represent the pond's ecosystem.

What is an ecosystem?

All the organisms and the physical setting they interact with make up an ecosystem. The nutrition cycles and energy flows connect these biotic and abiotic elements. Photosynthesis is how energy enters the system and is absorbed by plant tissue.

Producers, consumers, and decomposers are the three groups of living things that make up an ecosystem. Each of them contributes significantly to the ecosystem. Forest, desert, rainforest, grassland, tundra, savanna, and mountain habitats are the main categories of ecosystems.

Hence, a  pond has fish, crawfish, oysters, lilies, and algae. All these species represent the pond's ecosystem.

What characteristic could provide a species with a better chance of surviving a drastic environmental change?

(A) A small population size

(B) A highly diversified gene pool

(C) specialized cells within the body

(D) Many individuals with the recessive trait

Answers

the answer is B


Species with a limited variety of phenotypes and where all members of the species are similar to one another have a smaller chance of coping with environmental variability compared to a species with greater diversity.

A highly diversified gene pool could provide a species with a better chance of surviving a drastic environmental change. So, the correct option is B.

What is Diversified Gene pool?

Greater genetic diversity within a population is made possible by a diverse gene pool, which raises the possibility that at least some members of the population will exhibit features that are more adapted to the new environment.

This variety can develop as a result of gene flow from other populations or mutations. The number of people having the recessive trait or a limited population size, however, would not always give an advantage in enduring environmental change. A species may have a better chance of surviving a severe environmental shift if its gene pool is extremely varied.

Therefore, the correct option is B.

Which of the following is a source of energy made from plant and animal remains?

Answers

Fossil fuels are hydrocarbons, primarily coal, fuel oil or natural gas, formed from the remains of dead plants and animals.

In common dialogue, the term fossil fuel also includes hydrocarbon-containing natural resources that are not derived from animal or plant sources.

These are sometimes known instead as mineral fuels.

The utilization of fossil fuels has enabled large-scale industrial development and largely supplanted water-driven mills, as well as the combustion of wood or peat for heat.

Fossil fuel is a general term for buried combustible geologic deposits of organic materials, formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years.

The burning of fossil fuels by humans is the largest source of emissions of carbon dioxide, which is one of the greenhouse gases that allows radiative forcing and contributes to global warming.

A small portion of hydrocarbon-based fuels are biofuels derived from atmospheric carbon dioxide, and thus do not increase the net amount of carbon dioxide in the atmosphere.

Answers

Answer:

b

Explanation:

hormones of adrenal medulla are Adrenaline and non- Adrenaline. they are the derivatives of amino acids called Tyrosine( aromatic Amino acid)

The hormones of the adrenal medulla are modified versions of amino acids. Thus, the correct option is B.

What is the Adrenal medulla?

The adrenal medulla may be defined as an internal part or region of the adrenal gland which is located at the region of the top of each kidney.
