What led to scientists accepting Mendel's ideas?
A. Scientists discovered chromosomes and DNA.
B. Scientists discovered the scientific method.
C. Scientists repeated his experiments using other plants.
O D. Scientists developed the law of independent assortment.
Answer:
A. Scientists discovered chromosomes and DNA.
Explanation:
Mendel's ideas were based on patterns of inheritance in plants. Although he identified these patterns, at the time, we did not know what the hereditary material was. This means Mendel couldn't uncover the mechanism of why he was seeing the patterns he was.
When scientists discovered chromosomes and DNA, they were able to see how Mendel's observations made sense in the context of DNA and chromosomes.

Why is glucose the first option for energy release?
Why not proteins or fats?
Answer:
firstly you can follow me I can give you answer
Glucose is stored calories in the form of fat, and are the first to go becuase they provide the most long-term energy. Lipids are essential to your vital organs in keeping them protected and functional, like the lipids from healthy fats in your cardiovascular system. Proteins, like fatty acids, are utilized by your cells to undergo a variety of processes, including mitosis. Overall, it is a process most likely determined by evolution, and our bodies prioritize giving us the most energy at the moment, which is why you burn calories while running, playing sports, and even playing chess (chess players can burn upwards of 6,000 calories in a single 12-14 hour game, perhaps even longer).

question one: why do stars change very little while they are in the main sequence stage?
question two: why does a main sequence star eventually grows in size to become a red giant?
Answer:
Q1 As the main sequence star glows, hydrogen in its core is converted into helium by nuclear fusion. When the hydrogen supply in the core begins to run out, and the star is no longer generating heat by nuclear fusion, the core becomes unstable and contracts.
Q2When stars first begin to fuse hydrogen to helium, they lie on the zero-age main sequence. ... The core of a red giant is contracting, but the outer layers are expanding as a result of hydrogen fusion in a shell outside the core. The star gets larger, redder, and more luminous as it expands and cools.

10.
Photosynthesis deposits energy in Earth's "savings account" for living
organisms.
11.
Cellular respiration removes carbon dioxide from the air.
12.
Photosynthesis takes place in nearly all life.
Answer:
9. False
- opposite
10. True
11. False
- oxygen
12. False
- cellular respiration
False, true, false and false are the respective answers for the following statements.
What is similarity between photosynthesis and cellular respiration?During the process of photosynthesis, carbon dioxide and water are converted into oxygen and glucose. The plant digests glucose for fuel, and the production of oxygen is a by-product of this process.
During the process of cellular respiration, oxygen and glucose are converted into water and carbon dioxide. Water and carbon dioxide are the by-products of the process, while ATP is the energy that is converted throughout the reaction.
Therefore, photosynthesis remove carbon di oxide from the air.

In the event of a mismatched nucleotide , which molecule is able to backtrack , "proofread , " and correct the nucleotide sequence ?
A. DNA Proofreadase
B. DNA Polymerase
C. DNA Helicase
D. DNA Primase
Answer:
The molecule that is able to go back and correct an error in the DNA nucleotide sequence is DNA polymerase (option B).
Explanation:
DNA polymerase is not only the enzyme that contributes to the polymerization of a new DNA strand during the replication process, but it can also correct errors in synthesis, such as when a mismatched nucleotide is placed.
Once an error has been detected during synthesis, the DNA polymerase —acting as a 3'-5'- exonuclease— reverses the process, the direction of synthesis, to correct the error which in this case is the mismatched nucleotide.
The other options are not correct because:
A. DNA proofreadasa does not exist.
C. Helicase breaks the hydrogen bridges that bind the nucleotides allowing the separation of the DNA strands. In some cases, it also acts as a DNA repairer
D. DNA Primase is responsible for the synthesis of primers.
The molecule that is able to get back to the correct the errors in the DNA is DNA Polymerase.
The polymerase is a member of the family of enzymes which synthesis the DNA molecule and forms triphosphate. They are essential for the replication of the DNA.Hence the option B is correct.

???usually means clear weather because stable air is sinking.
O A. High humidity
B. Lower air pressure
C. Low humidity
D. Higher air pressure
High air pressure usually means clear weather because stable air is sinking. The correct option would be D.
High air pressureHigh air pressure usually causes the sky to be clear.
This is because high air pressure causes the air at the lower atmospheric level to sink down towards the earth.
This is unlike low air pressure. It brings a cloudy sky along with precipitation.

How do human beings negatively affect the carbon cycle?
Human beings burn fossil fuels, which contribute carbon dioxide to the atmosphere.
Human beings conserve resources, which decrease resources for the carbon cycle.
Human beings mine resources, which increases the amount of oxygen available to the carbon cycle.
Human beings use carbon-based pencils, which decreases the amount of carbon dioxide in the atmosphere.
Eww
Answer:
Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. ... This extra carbon dioxide is lowering the ocean's pH, through a process called ocean acidification.

Where in the cell does the krebs cycle part of cellular respiration occur ?
Answer:
In the mitochondrial matrix
Explanation:
The mitochondria is an organelle within the cytoplasm of the cell. It consists of an outer membrane, inner membrane, and matrix containing a gel-like substance. During aerobic respiration in mitochondria, cells break down sugars in the form of glucose into [tex]CO_{2}[/tex] (carbon dioxide) and [tex]H_{2} O[/tex] (water) to obtain energy in the form of ATP or adenosine triphosphate.
aerobic respiration:
C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
(glucose) (oxygen) (carbon dioxide) + (water)
The Kreb's cycle involves several enzymatic reactions, where pyruvate derivatives obtained from glycolysis, are reduced and oxidized to harvest energy as ATP.
