The combustion of biomass can replace fossil fuels in conventional power plants

In conventional power plants a source of heat is used heat liquid water to high-pressure steam and the steam is used to turn turbines with a dynamo effect that produces electricity. This source of energy can be anything that produces energy when decomposed.

Explanation:

Usually, this source of energy is fossil fuels because it is cheaper and has high calorific value. Biomass - carbon based organic matter such as dead tree logs- when burned, can produce heat energy required to turn water to steam, too. Biomass is a renewable source of energy in comparison to fossil fuels.

Hydroelectric energy emanates from the potential and kinetic energy of water, usually naturally flowing water, to turn turbines that produce electricity.

The sun is a renewable resources, unlike fossil fuels, because it is impossible to exhaust the sun's potential in all of the humanity’s existence on earth.

Answer:

The first blank can be filled with tagging. One of the procedures for studying the movements, biology, and migration of animals is known as tagging of animals. Tagging is utilized to examine the long-range irregular and regular movements of animals and to identify their life-span. All kinds of mollusks, vertebrates, and insects can be tagged.

Which of the following examples can cause gene flow between populations?

yanalaym [24]

The answer is <span>bird droppings that contain seeds from a different location.

</span><span>Gene flow includes a transfer of alleles from one population to another. So imagine a population of plant A on location 1 and another population of plant A on location 2. They cannot interchange their genes. But if birds drop seeds from location 1 and those seeds get to location 2, gene flow may occur.</span>

MaRussiya [10]

Answer:

A) Chromosomes are made of DNA

C) Alleles are the different forms of a gene that can exist

D) Chromosomes contain genes that control the inheritance of traits.

Explanation:

Chromosomes are long molecules of deoxyribonucleic acid (DNA) that contain part (or all) of the genetic material of an organism. Humans contain 46 chromosomes organized in 23 pairs of homologous chromosomes (22 pairs of autosomal chromosomes and one pair of sex chromosomes, X and Y). Moreover, a gene is a physical segment of a chromosome that contains the information to encode a protein. Alleles are different forms of a gene (i.e., gene variants) that may be caused by mutations or genetic recombination. Humans are diploid organisms (2N: 46), and therefore we have two copies of each gene (alleles), one on each homologous chromosome.
