Answer:
In the convective zone, the temperatures are cool enough—under 1,800,000 degrees Fahrenheit (1,000,000 degrees Kelvin)—that the atoms in the plasma there can absorb the photons coming outward from the Sun's radiative zone. The plasma gets very hot, and begins to rise upward out of the Sun.

5. Drug X blocks ATP regeneration from ADP and phosphate. How will muscle cells respond to this drug?
A. by absorbing ATP from the bloodstream
B. by using ADP as an energy source
C. by using glycogen as an energy source
D. none of the above
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.
What is effect of drug on ATP inhibition?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.

Put the stages of the nitrogen cycle in their correct order.
Fixation or volatilization, mineralization, nitrification, immobilization, and denitrification.
The sequence is as follow: Fixation, Nitrification, Assimilation, Ammonification and Dentrification.
What is a nitrogen cycle?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.

How has vehicle fuel consumption in comparison to miles traveled changed since 1960? What is the likely cause for this change?
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
Answer:-B: a unit of inheritance that transmits information
Explanation:-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.
What is a Gene?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.

what is Krebs cycle?
Is Krebs cycle also known as cellular respiration?
Explanation:
The tricarboxylic acid (TCA) cycle, also known as the Krebs or citric acid cycle, is the main source of energy for cells and an important part of aerobic respiration. It takes place in the mitochondria, using up oxygen and producing carbon dioxide and water as waste products, and ADP is converted to energy-rich ATP.
No Krebs cycle is not known as cellular respiration

this year there were 32 ants born in an ant hive. Due to the new pesticide that was used in the area, 32 died. With an overall population of 1000 ants in the hive, what is the change in population? Do you have a positive, negative, or zero change in population? How many members are in the new population?
Answer should contain the following information: work for calculating the change in population positive, negative, or zero change in population. Work for calculating the new population.
Answer:
0 change in population. I think.
Explanation:
first we are adding 32 ants to the total because 32 ants were born so 1000+32 = 1032.
Next we are subtracting 32 ants from the new total because a pesticinde was used in the area. So 1032 - 32 is 1000. 1000 was the original total so there was not a decrease in popualtion or an increase.
