Genetic recombination plays a role in both maintenance and diversity within an organism. Explain how this balance is achieved and the underlying mechanism of recombination that are involved.
Answer:
Crossing-over between homologous chromosomes (prophase 1), the random lining of homologous chromosomes (metaphase 1), and random fertilization are the mechanisms involved in genetic variation.
Explanation:
Crossing-over between homologous chromosomes (prophase 1), the random lining of homologous chromosomes (metaphase 1), and random fertilization are the mechanisms involved in genetic variation.
The Crossing-over events occur between two homologous chromosomes in the equatorial plane and make the daughter cells genetically different from the original one. The Chiasma is the position where two homologous chromatids interchange genetic information, giving a place for new genetic material or information to be provided to descendants. After crossing over, homologous chromosomes get separated again.
On the equatorial plane, homologous paired together, randomly aline with their kinetochores facing opposite poles. The random arrangement of tetrads is different in every cell going through the meiosis process. There is no equal alinement between two cells. When tetrads aline in the equatorial plane, there is no predetermined order for each of the homologous chromosomes of each tetrad to face one of the poles and then migrate to it while separating. Chromosomes of the homologous pair arrange to face any of the poles to migrate forward to it. Each of the chromosomes has two possibilities for orientation at the plane. When the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell. The order in the equatorial plane is what introduces variation into the gametes, being almost impossible for two gametes to have the same genetic charge.
Independent assortment occurs when the alleles from two or more different genes distribute in gametes independently from each other. In other words, a gamete receives an allele from a gene that does not depend on nor influence the allele of another gene in the same gamete. This can only be applied to independent genes. An organism gets only one of the members of the chromatids pair of each parent.

MacConkey Agar contains crystal violet which binds to gram positive bacteria, preventing them from growing. The media turns yellow in response to the production of acid when lactose is fermented. Which two terms best describe this media
Answer:
The media describes Selective and Differential.
Explanation:
Given - MacConkey Agar contains crystal violet which binds to gram positive bacteria, preventing them from growing. The media turns yellow in response to the production of acid when lactose is fermented.
To find - Which two terms best describe this media ?
Proof -
The media describes Selective and Differential.
Reason -
MacConkey is a selective and differential media.
This media is used to selectively isolate gram-negative bacteria from other bacteria and differentiate them on the basis of lactose fermentation.
Lactose fermenters turn red or pink on MacConkey agar, and non-fermenters do not change color.

If Walter waters his plants daily, then his plants will grow. Walter's plants are not growing. Thus, we can conclude Walter has not been watering his plants. Is this an example of inductive or deductive reasoning
Answer:
The correct answer is - deductive reasoning
Explanation:
Deduction reasoning is a general reasoning process that starts from a basic or general thought or idea and then a conclusion is based upon that idea. These ideas are presumed to be true and known. It is a deductive argument that based on known premises and conclusions would be specified.
Inductive reasoning provides specific cases to more general, but not necessarily true, conclusions. In the given question the ideas or premises are more specific and perceived to be true and the conclusion is specific thus, it is a deductive reasoning.

what is adaptive radiation
Answer:
Adaptive radiation is the process where organisms diversify rapidly from an ancestral species to a multitude of different, new forms. More particularly when a change in the environment makes new resources available.
The process of natural selection is seen most quickly in organisms that can reproduce many generations in the shortest amount of time. Based upon this information, which type of organism would exhibit the most rapid rate of evolution?
1.bacteria
2.fruit flies
3.finches
4.humans
Answer:
2
Explanation:
one time within 2 days my house was filled with fruit flies
Answer:
Bacteria
Explanation:
Bacteria reproduce most quickly . Fruit flies can go from the egg to sexual maturity in 3 weeks while bacteria can reproduce once they are "born" and can do so multiple times a day, while fruit flies can reproduce if mature once every day about.
Finches and humans obviously have much slower rates of reproduction.
3. Which statement describes a difference between

certain bacteria.
O c. The carbon cycle requires freezing
temperatures.
d. The nitrogen cycle occurs entirely in
the ocean.
Answer:
a.
Explanation:
The carbon cycle involves only plants. The nitrogen cycle requires a process called fixation, which makes the nitrogen more usable for living organisms. The carbon cycle requires that temperatures be above 27 °C (80 °F).

The statement that best describes a difference between the nitrogen and carbon cycles is the nitrogen cycle requires a process called nitrogen fixation that is carried out by certain bacteria.
What are the main differences between the nitrogen and carbon cycles?The main difference between nitrogen cycle and carbon cycle is that nitrogen cycle describes the conversion of nitrogen into multiple chemical forms and its movement between the different ecosystems. Whereas the carbon cycle describes the movement of carbon and its multiple chemical forms between the atmosphere, lithosphere and hydrosphere.
Microbes are involved in the nitrogen cycle process. Both plants and animals participate in the carbon cycle.
Thus, the statement that best describes a difference between the nitrogen and carbon cycles is option (b).

According to the Big Bang theory, what happens if you reverse the galaxy motion and go back in time?
A. Everything would become condensed into one dense point
B. Some things would remain the same, while others go back
C. Everything would be the same as it is today.
D. You would find everything in a large cloud of cold isolated gas
According to the Big Bang theory, if you reverse the galaxy motion and go back in time A. Everything would become condensed into one dense point.
The Big Bang Theory simply explains how the universe was formed from a large explosion. According to the Big Bang theory, the universe was formed as a result of the explosion of particles.
The reverse of the Big Bang Theory simply means the scenario where the expansion of the universe reverses. This is also called the Big Crunch. This will lead to the recollapse of the universe.
In this case, the cosmic scale also reaches zero. Then, everything would become condensed into one dense point.

Why would she do that
Answer:
In order to increase the permeability of the cell membrane.
Explanation:
A genetic engineerer apply jolts from electricity or high heat to bacterial cell walls during transformation in order to increase the permeability of the cell membrane. Increasing permeability of the cell membrane allows the genetic engineerer to insert the desired chemicals, drugs, or DNA into the cell. If she did not increase the permeability of the cell, no or less materials pass through the membrane and there is less chance of having transformation.
