A scientist carried out an experiment to follow the movement of carbon atoms within animal cells. To do this, the scientist added glucose with radioactively labeled carbon atoms to a culture of cells growing in a Petri dish.

After a certain amount of time had passed, the scientist tested parts of cells for radioactivity. Radioactivity was detected in various biomolecules, including DNA.


Which of the following statements best explains why radioactivity was detected in the DNA?
Choose 1 answer:

(Choice A)
The DNA was in close proximity to the radioactive glucose during its formation.

(Choice B)
Carbon atoms that were once in the radioactively labeled glucose were used to form DNA.

(Choice C)
The DNA was made up of radioactively labeled glucose subunits.

Explanation:

The muscle would contract with isotonic force. The muscle would contract isometrically. As a result of the actin-myosin cross bridges' inability to persist, the muscle would relax and lengthen. Thus, option D is correct.

Efrapeptins and aurovertins, two types of antibiotics, prevent ATP synthase from producing or breaking down ATP.

The rotor, the core cavity of the enzyme, and the particular -subunit catalytic site are where the efrapeptins bind to ATP synthase. This is because there won't be an ATP synthase-driven proton gradient.

The inability of the inner mitochondrial membrane to remain impermeable to protons or the cessation of electron transport will prevent oxidative phosphorylation from taking place.

Therefore, muscle contract with isotonic force.

Answer:

After World War II, economic growth, population growth, rapid suburbanization, and the closing of some public transit systems led to more reliance on personal vehicles for transportation. The number of cars and trucks in the United States increased dramatically, as did the number of highways. One result of the rapid increase of motor vehicles was air pollution, especially in cities, that had serious impacts on public health and the environment.

Which is another way to describe a gene?

A: a sequence of three base pairs

B: a unit of inheritance that transmits information

C: a short segment of information that is translated and taken out of the nucleus

B: a unit of inheritance that transmits information

A gene is the basic unit of heredity that occupies a specific position on a chromosome. Each is composed of linearly arranged nucleotides.

In another way, a gene may be described as a unit of inheritance that transmits information. Thus, the correct option is B.

A gene may be defined as a stretch of a segment that is present in the chromosome and helps to determine a characteristic.

Genes are present in the chromosomes of an organism. Genes carry out the instructions to construct molecules called proteins which induce specialized operations and build up the structure of living organisms.

Therefore, the correct option for this question is B.

The bombardment of the earth by solid particles affects its temperature because the bombardments release heat and make the earth warmer, and due to this, the early earth was hotter.

The Earth is the planet in the solar system that moves around the sun, and it has living plants and animals along with non-living substances such as soil, air, water, etc. Most of the earth is covered with water and the earth has various populations, biomes, and biodiversities, and all of this biodiversity is due to changes in climate and geography, which result in the presence of various animals.

Hence, the bombardment of the earth by solid particles affects its temperature because the bombardments release heat and make the earth warmer, and due to this, the early earth was hotter.

Fixation or volatilization, mineralization, nitrification, immobilization, and denitrification.

The sequence is as follow: Fixation, Nitrification, Assimilation, Ammonification and Dentrification.

The nitrogen cycle is the process by which nitrogen is converted into different chemical forms and moves between the biosphere, atmosphere, and geosphere. The stages of the nitrogen cycle, in order, are:

Nitrogen fixation: Nitrogen gas in the atmosphere is converted into a usable form, such as ammonia or nitrite, by nitrogen-fixing bacteria.

Nitrification: Ammonia or nitrite is converted into nitrate by nitrifying bacteria.

Assimilation: Nitrate is taken up by plants and converted into organic nitrogen compounds, such as proteins and nucleic acids, through the process of assimilation.

Ammonification: Organic nitrogen compounds are broken down by decomposers, such as bacteria and fungi, into ammonia or amino acids.

Denitrification: Ammonia or nitrite is converted back into nitrogen gas by denitrifying bacteria, completing the cycle.
