When your muscle cells do not get enough oxygen, fermentation can create?
Answer:
Your muscles are forced to work without enough oxygen. In these situations, your working muscles generate ATP anaerobically (i.e., without oxygen) using a process called fermentation. Fermentation is beneficial in that it can generate ATP quickly for working muscle cells when oxygen is scarce.
Explanation:
When oxygen is not present or if an organism is not able to undergo aerobic respiration, pyruvate will undergo a process called fermentation. Fermentation does not require oxygen and is therefore anaerobic. Fermentation will replenish NAD+ from the NADH + H+ produced in glycolysis.
If more carbon dioxide was made
available to a plant, what would be the
effect on the rate of photosynthesis?
A. The rate would be unaffected.
B. The rate would increase.
C. The rate would decrease.
Answer:
B. The rate would increase.
Explanation:
Increased carbon dioxide concentration increases the rate at which carbon is absorbed into the carbohydrate in an independent reaction, so the level of photosynthesis usually increases.

Explanation:
Cellular respiration is a process in which animal cells use ____ taken in from the atmosphere.
1) carbon dioxide
2) hydrogen
3) oxygen
Answer:
How does cellular respiration work in animals?
When an animal breathes, it takes in oxygen gas and releases carbon dioxide gas into the atmosphere. This carbon dioxide is a waste product produced by the animal's cells during cellular respiration. Cellular respiration occurs in the individual cells. Digested foods have chemical energy stored in them.
Explanation:
What helps to transport materials across the membrane, can open and close, or even change shape?
proteins
glucose
cells
We have learned Kepler's Laws, Newtons laws of Motion and Gravity, as well as where planets are in relationship to the sun. Knowing these things can you provide two generalized statements about the planets and yourself or about the planets and the laws.
Answer:
''Planets moves around the sun with constantly changing speed.''
''The sun uses its gravity to pull the planets towards it''
Explanation:
These two statements describes Newtons laws of Motion and Gravity. With statement 1, which shows the motion of the planets constantly changing due to the attraction of the sun. When the planets come close together to the sun, its orbital speed increases while on the other hand, when the planets goes farther from the sun, its orbital speed decreases. The statement 2 indicates that sun attracts other planets due to its gravity which allow them to move in a curved.
After cell division (mitosis) how does the genetic code of the newly
produced cells compare to the code of the parent cell?
Answer:
Chromosomes were first named by cytologists viewing dividing cells through a microscope. The modern definition of a chromosome now includes the function of heredity and the chemical composition. A chromosome is a DNA molecule that carries all or part of the hereditary information of an organism. In eukaryotic cells, the DNA is packaged with proteins in the nucleus, and varies in structure and appearance at different parts of the cell cycle.
Explanation:
Cells reproduce genetically identical copies of themselves by cycles of cell growth and division. The cell cycle diagram on the left shows that a cell division cycle consists of 4 stages:
G1 is the period after cell division, and before the start of DNA replication. Cells grow and monitor their environment to determine whether they should initiate another round of cell division.
S is the period of DNA synthesis, where cells replicate their chromosomes.
G2 is the period between the end of DNA replication and the start of cell division. Cells check to make sure DNA replication has successfully completed, and make any necessary repairs.
M is the actual period of cell division, consisting of prophase, metaphase, anaphase, telophase, and cytokinesis.
about artificial selection, determine if YOU think the benefits of artificial selection outweigh the disadvantages.
PLEASE HELP!!!!
Answer:
What YOU think
Explanation:
That's what it asks, but here are some points to help you along your way: Artificial selection has brought about the extinction or overpopulation of certain species. This can be seen in the avocado or banana industry. Consumers like the smaller, sweeter species of avocadoes. This caused that species to explode and the old ones to become endangered as farmers grew only that type and bred them selectively. Consumers like the smaller, less mushy, less sweet banana species, so now an amazing species of banana is extinct because the forests that used to have them now no longer exist or were changed to grow only that type of banana. Flip it to the animal side, and it's the same story. Those turkeys that the president "Saves" every year? because of artificial selection, that turkey dies a few weeks later because he grew too plump. Why? Because those turkeys are artificially selected to grow much larger than a normal turkey, and their lifespan is not in mind as they are grown for meat. Also, I hope all of this work gives me brainliest :/
