Scientists can identify the gene mutated in a bacterial auxotroph by transforming the cells with a genomic library in which fragments of the auxotroph's genome have been cloned into plasmids.
a. True
b. False
Answer: false
Explanation: this can only be true if the genes in the genomic library fragments have been identified and if the mutation is an SNP and not an inversion or deletion or insertion, whether they were cloned into plasmids or not.

Imagine an animal cell lost half of its mitochondria. Explain how the cell would be different.
YOU WILL GET 100 POINTS.
Answer:
Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration. ...
Explanation:
Mitochondria are rod-shaped organelles that can be considered the power generators of the cell, converting oxygen and nutrients into adenosine triphosphate (ATP). ATP is the chemical energy "currency" of the cell that powers the cell's metabolic activities. This process is called aerobic respiration and is the reason animals breathe oxygen. Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration. In fact, mitochondria enable cells to produce 15 times more ATP than they could otherwise, and complex animals, like humans, need large amounts of energy in order to survive.
mitochondrion is different from most other organelles because it has its own circular DNA (similar to the DNA of prokaryotes) and reproduces independently of the cell in which it is found; an apparent case of endosymbiosis. Scientists hypothesize that millions of years ago small, free-living prokaryotes were engulfed, but not consumed, by larger prokaryotes, perhaps because they were able to resist the digestive enzymes of the host organism. The two organisms developed a symbiotic relationship over time, the larger organism providing the smaller with ample nutrients and the smaller organism providing ATP molecules to the larger one. Eventually, according to this view, the larger organism developed into the eukaryotic cell and the smaller organism into the mitochondrion.
in most animal species, mitochondria appear to be primarily inherited through the maternal lineage, though some recent evidence suggests that in rare instances mitochondria may also be inherited via a paternal route. Typically, a sperm carries mitochondria in its tail as an energy source for its long journey to the egg. When the sperm attaches to the egg during fertilization, the tail falls off. Consequently, the only mitochondria the new organism usually gets are from the egg its mother provided. Therefore, unlike nuclear DNA, mitochondrial DNA doesn't get shuffled every generation, so it is presumed to change at a slower rate, which is useful for the study of human evolution. Mitochondrial DNA is also used in forensic science as a tool for identifying corpses or body parts, and has been implicated in a number of genetic diseases, such as Alzheimer's disease and diabetes.

Explanation:
why are fossil fuels considered finite?
Answer:
A finite resource is something that can only be consumed once without possibility of being recycled for re-use. Because fossil fuels are burned, they cannot be reused and are therefore a finite resource.
Explanation:
Why do people, animals, and all other organisms do cellular respiration?
O To make food/glucose for themselves. As a byproduct they make the oxygen that we need.
O To make carbon dioxide and water that animals can use.

Explain how asexual reproduction works. what organisms undergo asexual reproduction?
Answer:
Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction, either from a single cell or from a multicellular organism, inherit the genes of their single parent.

After concluding his research, which statements would Virchow agree with? CHECK ALL THAT APPLY.
Living things come from nonliving things.
Cells can come from nonliving materials.
Frogs can come from mud.
Living things can only come from living things.
Cells come from pre-existing cells.
Answer:
Living things can only come from living things.
Cells come from pre-existing cells.
Explanation:
Rudolf Virchow a german physicist, biologist and many more, In 1855 Vproposed that cells come from pre-existing based on his observations in exact words 'Omnis cellula e cellula', which translates into all cells arise from pre-existing cells.
He also said the living things come from living things and do not arise from nonliving things or matter. His discoveries made possible the cell theory

Explanation:
anyone help please
need answer immediately
Answer:
1. It's difficult to find out if someone is blood doping because the body has red blood cells. First the doctors get blood samples. Because the body constantly produces new blood, the blood that was stored shows that it is old with the blood samples it shows that there are some new and some old blood cells, which is how you can tell if they are doping.
2. Hemoglobin is a protein that is produced by the body that carries oxygen in the red blood cells the more red blood cells the more hemoglobin you have. Ex; If the athletes have a high level of hemoglobin on the day of the race than it had been days or weeks before, to shows that the athlete was blood doping.
3. It can help the body produce more blood cells to carry more oxygen (get more energy) and the body can get used to that kind of high altitudes and climates. Which leads to you getting even more energy at lower altitude levels.

from a particular location on earth, why can we see many more total eclipses of the moon that the total eclipses of the sun?
Answer:
Hiii! I'm here to help!
Explanation:
The Moon is always in the same place in our sky while the Sun moves around the sky. The Moon is much bigger in the sky than the Sun. The line-up of the Earth Moon and Sun needed for a lunar eclipse happens many many times more often than what is needed for a solar eclipse. A total lunar eclipse is visible over a much larger part of the Earth's surface than a total solar eclipse.
