Nuclear power has come under higher scrutiny in recent years. Which statement would make the strongest for the use of nuclear po
Tamiku [17]

The Answer is A) Nuclear power generates large amounts of power limited to projection of greenhouse gases.

I believe this is the answer. As per the reports in 1998, it has been calculated the emission of the greenhouse gas has reduced for nearly half due to the popularity in the use of nuclear power. Nuclear energy by far has the lowest impact on the environment since it does not releases any gases like carbon dioxide, methane which are largely responsible for greenhouse effect. There is no adverse effect on water, land or any habitats due to the use of it. Though some greenhouse gases are released while transporting fuel or extracting energy from uranium.

Have a great day. Keep asking questions!

Answer:

E

Explanation:

A mutation that confers phenotypic benefits to individuals or a group of individuals would be considered a beneficial mutation.

<em>Mutation involves a sudden change to the gene coding sequence of the DNA. It can occur as a result of substitution, duplication, deletion, inversion, insertion, etc of purine or pyrimidine bases of the DNA.</em>

<u>These changes can be harmful, beneficial, or neutral to individuals. Those that have neutral effects in individuals are also called silent mutations.</u>

In the case of a duplication causing trichomatic vision in humans, it represents a form of beneficial mutation because it enables humans to be able to distinguish between red, green, and blue colors. The ability to distinguish among these colors improves the quality of life of humans.

Match Column A with Column B
crimeas [40]

Answer:

3.1.1 Division of the cytoplasm - Cytokinesis

3.1.2 Uncontrolled cell growth - Cancer

3.1.3 Chromatids lined up at equator of cell - Metaphase

3.1.4 Chromatids joined at this point - Centromere

3.1.5 Mass of cancerous cells - Tumor

3.1.6 Skin cancer - Carcinoma

3.1.7 Growth and mitosis - Meristematic

3.1.8 Cancer causing factors - Carcinogens

3.1.9 Cancer cells that do not spread - Benign

3.1.10 Replicated half of a chromosome - Chromatid

Explanation:

The division of the cytoplasm is known as Cytokinesis. It occurs during the later part of the division of the nucleus in both mitosis and meiosis. In Cytokinesis, the cytoplasm of a single parent cell divides in two to produce two daughter cells.

Cancer is a disease condition that results when the growth and division of cells is uncontrolled. It occurs as a result of changes to the DNA either due to environmental factors or heredity factors.

Metaphase is one of the four stages in mitosis. During mitosis, the chromatids which are joined at the centelomere line up at the middle or equator of the cell.

Centromere is a region in the chromosome in which sister chromatids are joined together to form a short and a long arm of the chromosome.

A tumour is a swelling of a part of the body due to the abnormal growth of cells in that part of the body. A tumour may have the ability to spread or not.

Cancers that originate in the skin or tissues lining organs is known as carcinomas.

In plants, meristematic tissues are responsible for growth as they consist of actively dividing or mitotic cells. Meristematic cells are present at the tips of roots,stem and branches.

Carcinogens are agents or factors that are able to cause cancers. They include such agents like chemicals, electromagnetic radiations, some viruses, lifestyle factors, etc.

Benign tumours refers to growths in tissues or organs of the body which are non-cancerous as they do not spread to other tissues or organs in the body.

A chromatid is one-half of a replicated chromosome present in the nucleus of the cell. Two chromatids are joined together at the centromere to form the chromosome.

Where is the Electron Transport System (ETS) located in prokaryotic cells?
kenny6666 [7]

Answer:

Cellular membrane.

Explanation:

In prokaryotes electron transport chain isIn prokaryotes electron transport chain is located in the cell membrane. ETC is defined as the series of complexes which helps in the transfer of electrons from electron donors to electron acceptors via reduction, and oxidation reaction couple the transfer of protons with electron transport across a member.

The primary function of the ETC is generated a transmembrane proton electrochemical gradient, such as oxidation, and reduction reaction.
