How does the chromosome number of daughter cells compare with the amount of chromosomes in parent cells?
Answers
Answer:
Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.

if random chromosome alignment already shuffles chromosomes around so the eggs and sperm get a good mix of some “mom” alleles and some “dad” alleles, why do we even need to do crossing over
Answers
Answer:
The correct answer is - to produce recombinant that leads to genetic variation.
Explanation:
Random shuffling or random alignment of the chromosome during gamete formation allows the formation of new allele combinations. In the crossing over the parts of the homologous chromosomes are switched between homologous and recombinants are formed that shows are genetic variation.
So, now they have different allele combinations and chromosome combinations as well. Random shuffling does not provide genetic variations as crossing over
where in the cell does the electron transport part of the cellular respiration occur ?
Answers
Answer:
mitochondria
The Krebs cycle and electron transport occur in the mitochondria. The Krebs cycle takes place in the matrix, and electron transport takes place on the inner membrane. During the Krebs cycle, pyruvate undergoes a series of reactions to produce two more molecules of ATP and also several molecules of NADH and FADH2.
Homeostasis is maintained by which of the following organ systems in humans?
A. Multiple organ systems working together
B. The muscular system
C. The endocrine system
D. The nervous system
Answers
A. Multiple organ systems working together
Explanation:
All of the organ systems work together to maintain homeostasis in humans because each system does something different. For example, the circulatory system delivers oxygen rich blood to the bones and the bones create new blood cells. When one thing is wrong with one system, it affects all of the systems, like a disease. Another example of this would be the central nervous systems and endocrine working together to coordinate messages to the brain about the body's state while resting and exercising to maintain homeostasis.
In periods of hot, dry weather, the small pores (holes) on the surface of leaves of most plants will close in order to reduce water loss. When these pores are closed, carbon dioxide is restricted from entering the leaf. As a result, what product will also decrease? a. Cellular respiratory b. Water c. Glucose d. Carbon dioxide
Answers
The stomata of plants will close during hot and dry day. This cause a decrease in concentration of carbon dioxide and increase in oxygen concentration in the plant. Photorespiration occur.
As carbon dioxide in photosynthesis is used to produce glucose molecules, the production of glucose molecule will decrease.

What occurs is ecological succession. When an entire ecosystem is suddenly changed due to a catastrophic scenario it gets replaced by another. Other plants or animals replace the ones that got wiped out in an event such as a big forest fire or flood.

Which best describes a codon?
a cell structure that gives the master instructions for an organism
a segment of DNA that is the basis of heredity in organisms
the sequence of three bases that codes for a specific amino acid
the basic unit of structure and function of all living things
Answers
Answer: the sequence of three bases that codes for a specific amino acid
Explanation: I took the test and i got this answer correct so i hoped this helped!!
Codons are generally a sequence of three bases in the DNA and RNA that codes for specific amino acids. So option C is correct.
What is a genetic code?A genetic code is a set of information that helps to convert the genetic information stored inside the genetic material into a defined sequence of amino acids called a protein.
Though the DNA has nucleotide sequences that contain information for producing the proteins, the DNA cannot directly synthesize the proteins. It is first converted to mRNA in order to be translated into a specific protein.
There are in total 64 codons, out of which 61 code for specific amino acids while the remaining three codons are known as stop codons and are used in terminating the process of translation of proteins.

Why do you think scientists call both liquids and gases by the same term-fluids?

Featured snippet from the web
A gas fills its container, taking both the shape and the volume of the container. Liquids and gases are called fluids because they can be made to flow, or move. In any fluid, the molecules themselves are in constant, random motion, colliding with each other and with the walls of any container.
If an individual has the genotype Bb, what alleles can it pass on to its
offspring?
A. Only B
B. Neither B norb
C. Either B or b
D. Only b
Answers
If a person possesses the genotype Bb, either the B or the b alleles can be passed on to their progeny. So, the correct option is C.
What is Genotype?An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual carries inside a specific gene or genetic region are also referred to as the genotype.
The term "genotype" relates to an organism's whole gene pool, or, in other words, the genetic make-up of that creature. The phrase can also be used to describe to the alleles, or different forms of a gene, that an organism carries in a more specific meaning. Symbols can be used to symbolise it. For illustration, BB, Bb, and bb could be used to denote a certain gene variant.
If a person has the genotype Bb, as in the example above, then either the B or the b alleles can indeed be passed on to their progeny.
Therefore, the correct option is C.

Q35. (2pts) Describe how the antidote (treatment) helped Jared's cells make ATP (include the ETC and H+ gradient in your answer).
This is from gizmos if you know this pls help me out
Answers
Answer:
The antidote entered into Jared's cell and targeted the cyanide that was disrupting his Electron Transport Ch...
Explanation:
The antidote entered into Jared's cell and targeted the cyanide that was disrupting his Electron Transport Chain. The antidote changes the cyanide into a molecule called thiocyanate. Jared’s body can now remove this molecule through his excretory system. As the cyanide is removed, electrons can now leave the ETC by reacting with O2 to make water. His ETC can now get new electrons from NADH this then means he is able to move more H+ into the inter-membrane space. Jared’s cells can now make ATP again.
The antidote binds cyanide. This binding impedes cyanide to inhibit the cytochrome oxidase action. As the cytochrome reactivates, electron transport reactivates as well, and ATP is synthesized again.
---------------------------------------------------------------------
Ion cyanide inhibits cellular respiration by binding to the ferric ion of cytochrome oxidase and blocking the electron transference.
Because the electron transporter chain is interrupted, there is no ATP production, and muscles do not get enough energy.
The antidote enters Jared's cells and targets cyanide.
When the antidote meets cyanide, it binds to this last one and blocks its effect on cytochrome oxidase.
As cyanide can no longer bind the ferric ion of cytochrome oxidase, the enzyme remains active, and the electron transport is reactivated.
As electrons move along the chain, protons are pomped to the intermembrane space.
ATP production reactivates again as well because the proton gradient is used to produce ATP molecules.

How might retaining too much heat be a disadvantage to an organism?
Answers
Excessively heat can damage the plasma membrane and disrupt subcellular structures such as membrane proteins and enzymes.
What are subcellular structures?The following are the primary subcellular structures found in animal cells: The nucleus is where genetic material is stored.
Cell membranes regulate what enters and exits the cell. Mitochondria: aerobic respiration site. Ribosomes are the sites where proteins are synthesized.
Protein denaturation occurs at high temperatures and affects protein folding, bonding, and other types of behavior.
Furthermore, membrane proteins play an important role in cell function regulation. If these are disrupted, the system will be unable to maintain homeostasis, or a stable internal environment.
Heat can damage the plasma membrane and disrupt subcellular structures like membrane proteins and enzymes.
Thus, this way, retaining too much heat can be a disadvantage to an organism.
