Answer: The number of adenines in one strand is equal to the number of thymines in the complemetary strand.

Explanation:

Deoxyribonucleic acid or DNA is a molecule that contains the genetic information in all living organisms. So it contains all the hereditary genetic information that has the instructions to development.  This DNA molecule consists of two strands that bond together to form a double helix structure. Each strand of DNA is made up of nucleotides which are basic chemical components made of a phosphate group, a sugar group and one of four types of alternative nitrogenous bases. The four types of nitrogenous bases found in the nucleotides are:

The sequence of these bases determines how genes are made, and each gene has different biological instructions to create proteins (that will have different functions in the organism). To form a DNA strand, the nucleotides are linked together in chains, alternating with the phosphate and sugar groups.

The nitrogenous bases are complementary between them. Adenine and thymine are complementary, as are guanine and cytosine. So since adenine is complementary to thymines, and cytosine is complementary to guanine, the number of adenines in one strand is equal to the number of thymines in the complemetary strand. And the number of cytosine is equal to the number of guanine.

DNA is composed of two complementary strands this is reflected in the fact of that - The amount of adenine in one strand is always equal to the amount of thymine in the complementary strand.

Thus, DNA is composed of two complementary strands this is reflected in the fact of that - The amount of adenine in one strand is always equal to the amount of thymine in the complementary strand.

Intense heat at Earth's core creates movement in the mantle, which in turn leads to movement in the crust as the earth has three layers, such as the innermost core and the outermost crust layer.

The earth is composed of several layers, each with unique properties and characteristics, such as the core, mantle, and crust, the core is made up of two layers: the inner core and the outer core, while the inner core is made up of solid iron and nickel and the outer core is a liquid layer of iron and nickel, the mantle is the thickest layer of the earth and is made up of solid rock present outside of the core, and the crust is the outermost layer of the earth and is made up of solid rock.

Hence, intense heat at Earth's core creates movement in the mantle, which in turn leads to movement in the crust as the earth has three layers, such as the innermost core and the outermost crust layer.

Answer:high ph is harmful to this type of plant

Explanation:

Answer:

Whether or not a given isotope is radioactive is a characteristic of that particular isotope. Some isotopes are stable indefinitely, while others are radioactive and decay through a characteristic form of emission. As time passes, less and less of the radioactive isotope will be present, and the level of radioactivity decreases. An interesting and useful aspect of radioactive decay is half-life, which is the amount of time it takes for one-half of a radioactive isotope to decay. The half-life of a specific radioactive isotope is constant; it is unaffected by coTnditions and is independent of the initial amount of that isotope.

Consider the following example. Suppose we have 100.0 g of tritium (a radioactive isotope of hydrogen). It has a half-life of 12.3 y. After 12.3 y, half of the sample will have decayed from hydrogen-3 to helium-3 by emitting a beta particle, so that only 50.0 g of the original tritium remains. After another 12.3 y—making a total of 24.6 y—another half of the remaining tritium will have decayed, leaving 25.0 g of tritium. After another 12.3 y—now a total of 36.9 y—another half of the remaining tritium will have decayed, leaving 12.5 g. This sequence of events is illustrated in Figure 15.1 “Radioactive Decay”.

Answer:

D

Explanation:

Savannah grassland biome is found in an area with an average precipitation of 76.2-101.6 cm. Therefore, option B is correct.

A region of grassland with scattered trees or groups of trees is how the savanna biome is frequently defined.

The savanna is a dry environment, making it difficult for tall plants like trees to flourish. The trees and grasses that thrive on the savanna have adapted to the dry climate and limited water supply.

In regions with savanna growth, a tropical wet and dry climate is prevalent. The annual precipitation averages between 30 and 50 inches, while the mean monthly temperatures are at or above 64 degrees Fahrenheit. Less than 4 inches are received per month during the dry season for at least five months out of the year. Hence, option B is correct.

Answer: Thermal energy

Explanation:

Answer:

Photosynthetic organisms were making oxygen, but it reacted with the iron dissolved in seawater to form iron oxide minerals on the ocean floor, creating banded iron formations. ... The oxygen that is now in the Earth's atmosphere was not there at the beginning.

Explanation:

Band formations are thought to develop from cyanobacteria. It was developed as product of cyanobacteria photosynthesis.

The other name of cyanobacteria is blue green algae.

The oceans must change  between aerobic and anoxic situations. This characteristic makes banded iron development of  direct indicators of oceanic oxygen levels, providing us with a data of Earth's oxygenation.

Banded iron formations are brought to have formed in sea water as the consequence of oxygen production by photosynthetic cyanobacteria. The oxygen joined  with dissolved iron in Earth's oceans to form insoluble iron oxides which precipitated out forming a thin layer on the ocean floor.

Answer:

DNA is a dynamic and adaptable molecule. As such, the nucleotide sequences found within it are subject to change as the result of mutation. Depending on how a particular mutation modifies an organism's genetic makeup, it can prove harmless, helpful, or even hurtful.

Explanation:

Answer: The correct option is C.

a new genetic variation occurs that allows individuals to have a reproductive and survival advantage.

Explanation:

It is a new genetic variation occurs that allows individuals to have a reproductive and survival advantage because natural selection is a survival mechanism in which organisms develop a variation in genetic traits or develop characteristics which help them to reproduce,survive,adapt to their environment and pass on these characteristics to their offsprings which can be transfer to generations.

Answer:

B. The genetic variation for the trait was exhausted.

Explanation:

Oil content is a quantitative trait, ie., a phenotypic feature that depends on the accumulative effects of many genes and the interaction of a genotype with its environment. During crop improvement, the plants (i.e., lines) containing desired alleles involved in the variation of this trait will be selected, thereby increasing oil content but simultaneously decreasing the genetic variation of the population. In consequence, after successive rounds of artificial selection, lines will not have sufficient genetic diversity to be again selected for this trait.
