a. interphase

Explanation:

The gap 1, gap 2, and synthesis stages of the cell cycle make up the interphase. Thus, the correct option is A.

The Cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next. The cell cycle can be divided into two phases. They are:

Interphase comprises the G1 phase, S-phase, and G2 phase. The G1 phase is the resting phase. DNA synthesis does not take place. It is involved in the synthesis of RNA and protein. S-phase deals with the synthesis of DNA and histone proteins.

While the G2 phase is the continuous synthesis of RNA and proteins. After this phase, a cell enters the M phase.

Therefore, the gap 1, gap 2, and synthesis stages of the cell cycle make up the interphase. Thus, the correct option is A.

The correct option is (c) Only hydrogen atoms are used to complete the valence requirements of carbon.

This is not true because many of the other atoms and functional groups can be used to complete the valence of four. Valence is number of bonds that atom can form. Carbon typically has four bonds.

Since, it can form up to six bonds with certain configurations. Hence, the other elements, molecules, and functional groups can be used to satisfy carbon’s valence requirements. For example, oxygen atoms can be used to form carboxyl groups and hydroxyl groups.

Nitrogen can be used in forming amines, amides, and nitriles. Chlorine, bromine, and fluorine can be used to form halides. Sulfur can be used to form sulfides, sulfoxides, and sulfones. Hydrogen atoms can also be used to form hydrocarbons.

Answer:

binary fission

Explanation:

Binary fission is the main type of reproduction of prokaryotic organisms. In binary fission, the prokaryotic cell first duplicates its DNA and then divides into two cells, each one receiving one complete DNA molecule. Since binary fission is a type of asexual reproduction, this process increases the prevalence of beneficial mutations in a bacterial population. Moreover, transduction refers to the process by which a virus transfers genetic information from one bacterium to another bacterium. Conjugation is also a sexual mode of transfer of DNA from a donor (F+) to a recipient (F−) bacterial cell by direct cell-to-cell contact. Finally, transformation refers to the transfer of genetic material by which bacteria take up exogenous DNA from the environment and integrate it in their genomes.

DNA is comprised of four different types of nucleotides. Each nucleotide consists of a pentose sugar, a phosphate group, and one of four nitrogenous bases. Adenine, guanine, cytosine, and thymine are the four nitrogenous bases. Adenine and guanine, which have a nine-member double-ring structure, are called purines. Cytosine and thymine, which have a six-member single-ring structure, are called pyrimidines.

Answer:

1. The enhanced greenhouse effect disrupts the Earth's climate equilibrium and has led to an increase in the global average surface temperatures.

2. Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect"   1 — warming that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping.

3. Greenhouse gases absorb some of the energy and trap it in the lower atmosphere. Less heat radiates into space, and Earth is warmer. ... Carbon dioxide, methane, water vapor, and nitrous oxide are naturally present in Earth's atmosphere.

4. Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide. It is one method of reducing the amount of carbon dioxide in the atmosphere with the goal of reducing global climate change.

5. As climate change caused by burning fossil fuels drives temperatures higher, the ocean warms, causing it to expand. ... Scientists have found that water draining from melting glaciers and ice sheets in polar and mountain regions is now also contributing to this rise in sea levels.

Answer: 1. Necessary because it keeps heat in and keeps the planet at the right temperature for life.

It can harm the planet if more pollution occurs and the greenhouse gas effect traps too much heat and causes global warming. 2. Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect"1 — warming that results Greenhouse gases let the sun's light shine onto the Earth's surface, but they trap the heat that reflects back up into the atmosphere. In this way, they act like the insulating glass walls of a greenhouse. The greenhouse effect keeps Earth's climate comfortable when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping. 3. Human activities contribute to global warming by increasing the greenhouse effect. ...

It is one method of reducing the amount of carbon dioxide in the atmosphere with the goal of reducing global climate change. Geologic carbon sequestration is the process of storing carbon dioxide (CO2) in underground geologic formations. The CO2 is usually pressurized until it becomes a liquid, and then it is injected into porous rock formations in geologic basins. 5. As climate change caused by burning fossil fuels drives temperatures higher, the ocean warms, causing it to expand. This expansion in turn causes sea levels to rise. ... There is now so much warming baked in to the global climate system that sea levels will continue to rise for centuries.

The correct answer is - The adaptive value of allele b increased.

Explanation:

In this given population of insects, there is an increase in the number of insects in the given time of five years as initially there were 2800 insects and after five years there are 4000 insects, however, it is not the most probable explanation for the change in the phenotype as phenotype change does not depend on the size of population alone.

In this case, there is a drastic increase in the number of the recessive allele in last five years that suggests that adaptive value is increased of recessive allele due to some environmental change or mutation in the gene.

A myocardial infarction comprises a series of changes in the cardiac tissue that originate when there is an inadequate blood flow to the heart muscle or a coronary artery becomes blocked.

It is characterized by the sudden appearance of a picture of ischemic suffering (lack of irrigation) to a part of the heart muscle produced by the acute and total obstruction of one of the coronary arteries.

It is recognized by the sudden appearance of the characteristic symptoms of intense pain in the chest, in the precordial area and a feeling of general malaise.

The weather in an area stays virtually the same for an entire week. Stationary front probably exists between the nearby air masses.

A front is the area of transition between two air masses with distinct humidity and temperature levels. Fronts can spread out over a very small area (less than 30 miles) or a very large area (more than 100 miles). The line between the two different air masses is represented by the frontal zone. The front is referred to as a cold front if the cold air mass is moving into an area of warmer air. The front is known as a warm front if the warm air mass is moving into an area of cooler air.

The type of front depends on the properties of the air mass as well as the direction in which it is moving.

Without specific data on the genetic diversity and health of each Mimulus species, it is challenging to determine which species would fare better against a pathogen infecting all Mimulus species.

Further research and data analysis would be necessary for a more accurate interpretation.

Based on the information provided, it is difficult to determine which specific species would fare better in response to a pathogen that infects all Mimulus species. However, we can make an educated interpretation based on certain factors.

Firstly, we need to consider the concept of genetic diversity. If there is higher genetic diversity within a species, it is more likely to possess individuals with a resistance to the pathogen. Therefore, the species with the highest genetic diversity may have a better chance of surviving the pathogen.

Secondly, the overall health and fitness of a species can play a role in its response to a pathogen. If a species is already weakened due to other factors such as habitat loss or environmental stress, it may be more susceptible to the pathogen. On the other hand, if a species is robust and healthy, it may have a better chance of combating the pathogen.

NK cells can enter tissue more easily and are activated by macrophage secreted cytokines, which inhibit cell proliferation.

The natural cell-killing process and the release of cytokines are just two of the ways that NK cells get rid of contaminated or stressed cells. Virus-infected or tumor cells that are exposed to NATURAL KILLER CELLS undergo apoptosis. Apoptotic and aging cells are eliminated by macrophages. In addition to assisting phagocytes in locating and ingesting bacteria, the COMPLEMENT SYSTEM also causes direct lysis of microorganisms.

The establishment of a lytic immunological synapse between the NK cell and its target is triggered by target cell recognition. The target cell is subsequently specifically killed by the release of cytotoxic materials from secretory lysosomes at the lytic synapse, which is caused by the activation of their polarized exocytosis.
