B: a process of energy conversion that captures light energy and transforms it into chemical energy

C: a process of energy trarsfer that converts liquid water into water vapor

Answers

Answer:

B.) A process of Energy conversion that captures light energy and transforms it into chemical Energy.

Explanation:

Tectonic plates are defined as huge pieces of Earth's crust and uppermost mantle that are made up of oceanic crust and continental crust. Earthquakes occur around major faults that mark mid-ocean ridges and plate edges.

These plates act like hard and rigid shells in comparison to Earth's mantle which is the strong outer layer called lithosphere. At tectonic plate boundaries, rocky material is brought to the Earth's surface from its interior and from the Earth's surface to its interior.

You read an article on a website that suggests that there may be a new form of cancer-causing mutagen that causes the DNA backbone structure to be disrupted in its normal sequence. Using your knowledge of the structure of the DNA molecule, explain how you might hypothesize such a mutagen might impact the ability for the DNA molecule to do its job effectively.

Answers

Answer:

The mutagen might alter the DNA sequence, thereby altering the accessibility to transcription factors and thus activate the expression of oncogenes involved in cell proliferation

Explanation:

The DNA molecule consists of two antiparallel strands of nucleotides that wind around each other. Each DNA strand is formed by a backbone containing sugar (deoxyribose) and phosphate groups. This arrangement allows for DNA replication and transcription (and consequently also protein synthesis) to occur. If a mutagen agent binds to DNA, this might modify its structure, thereby altering DNA replication and transcriptional activity.

What causes nucleotides to switch locations in a DNA molecule?

Answers

Answer:

Explanation:

DNA is composed of two complementary strands this is reflected in the fact of that

Answers

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:

Adenine (A)Thymine (T)Guanine (G) Cytosine (C).

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.

A stable double helix of DNAthe two strands of DNA are antiparallel which means if one strand is, the 5' → 3' direction of one strand runs opposite to the other strand.The two DNA chains are held together by complementary base pairing between A and T bases and between G and C bases.The hydrogen bonds are found between the bases of the two strands of nucleotides.Adenine forms hydrogen bonds with thymine whereas guanine forms hydrogen bonds with cytosine.This is called complementary base pairing.

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.

Hydrogen - 3 is a radioisotope with a half life of 12.32 years. How long would it take a 40 g sample to decay down 2.5 g ?

Answers

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”.

Farmers have selected for increased oil content from corn. For a long time, the plants responded with steadily increasing oil content, but recently the response slowed and then stopped. When this line of corn is crossed to another line and the hybrids are selected, the oil content resumed its climb. What is a plausible reason for the lack of response?
A. The environmental conditions improved.
B. The genetic variation for the trait was exhausted.
C. There was too much genetic variation for the trait.
D. The environmental conditions deteriorated.
E. Artificial selection is different than natural selection.

Answers

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.
