Why is it important that mitosis occurs like this
Answer: The cell divides upon these processes during a process known as mitosis. In mitosis, two daughter cells are formed. It is important that each of the daughter cells contain genetic information that is identical to that of the mother cell, as well as that there be no mutations. Mitosis is Important for three main things:
> Growth
> Repair
> Reproduction

deletion mutation
chromosomal mutation
substitution mutation
Answer:
Deletion
Explanation:
because one base is deleted.
The mutation from A T A C G G T A G C A A to A T C G G T A G C A A is a deletion mutation.
MUTATION:Mutation is referred to as any change in the nucleotide sequence of DNA molecule. Mutation can be of different types namely: deletion mutation, substitution, insertion mutation etc. Deletion mutation is a kind of mutation that involves the removal of one or more nucleotide base from the DNA sequence. According to this question, an original sequence is given as: A T A C G G T A G C A A, mutation occurs and results in the following sequence: A T C G G T A G C A A. Nucleotide base "A" was removed from this sequence, hence, it is an example of deletion mutation.Learn more about deletion mutation at: https://brainly.com/question/6477597?referrer=searchResults
if mammalian cells receive a go-ahead signal at the g1 checkpoint, they will:
If mammalian cells receive a go-ahead signal at the G1 checkpoint, they will complete the cell cycle and divide normally.
What is the Cell Cycle?The cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next nuclear division.
There are three major checkpoints in the cell cycle. One at the end of the G1 phase, the second at the end of the G2 phase, and while third is during the M phase.
Therefore, if mammalian cells receive a go-ahead signal at the G1 checkpoint, they will complete the cell cycle and divide normally.

Which two atoms form an ionic bond?
A.sodium and bromine
B. two sodium atoms
C. two oxygen atoms
D fluorine and chlorine
Answer:
sodium and bromine
Explanation:
The one valence electron from sodium would be transferred to the bromine atom so they can both have an octet.
Which two atoms form an ionic bond?
Answer : A
Explanation : Ionic bond is a type of chemical bond and binds the chemical molecules together. Ionic bond is formed by the transfer of electrons from an electropositive element ( metal) to the electronegative element (non metal).
Sodium is an electropositive element and contains one positive charge. Bromine is an electronegative element with a single negative charge over it. Sodium gives the electron to bromine and results in the formation of ionic bond.
Thus, the correct answer is option (C).

Explain how pollution from one location
can affect the environment far away from the
source of the pollution
Answer:
Air quality is affected by natural processes. Wind can move pollutants from their source to far-away locations. It can still spread and harm living creatures and destroy their environments.
Explanation:
Air quality is affected by natural processes where wind can carry pollutants to places far away from their source which can still spread and harm living beings and destroy their environments.
What is Pollution?Pollution is defined as the introduction of harmful materials into the environment where the harmful materials are called pollutants. Pollutants can be natural, such as volcanic ash which can also be created by human activity, such as waste or runoff produced by factories. Pollutants harm the quality of air, water and land.
Many things produce pollution such as cars spewing pollutants from their exhaust pipes. Burning coal to generate electricity pollutes the air. Industries and homes generate waste and sewage that can pollute land and water. Pesticides which is chemical poisons used to kill weeds and insects which is seep into waterways and harm wildlife.
Thus, air quality is affected by natural processes where wind can carry pollutants to places far away from their source which can still spread and harm living beings and destroy their environments.

F- Cell wall
Explanation:
This is a structure of a plant cell which unlike animal cell has a cell wall as well as plasma membrane. It also contains large vacuoles present in the center of the cell. The green color of the plants is due to the presence of chlorophyll which is present in an organelles called chloroplast.
Organelles which are labelled in the cell are
A:Cell membrane
B:Vacuole
C:Nucleus
D:Cytoplasm
E:Chloroplast
F:Cell wall
The given figure represents a plant cell. So, the correct option is C.
What is Plant cell?Plant cells are defined as eukaryotic cells that contain a true nucleus as well as specialized structures known as organelles that perform certain specialized functions. Plant and animal cells both contain a nucleus with similar organelles but plant cells differ due to the presence of a cell wall outside the cell membrane.
In the given figure, labelled organelles function are as follows:
Vacuole stores food, extra water, and waste while cell membrane permits selective passage of things into and out of the cell. The cell's nucleus serves as the activity's control centre, while the cytoplasm is the fluid that gives the cell its jelly-like consistency. Chloroplasts contain a substance called chlorophyll that is a green pigment that aids in photosynthesis. The cell wall of a plant gives it form, stiffness, strength, and protection.
Thus, the given figure represents a plant cell. So, the correct option is C.

Some researchers argue that the robust australopiths should be classified in a separate genus. What is that genus called
Answer: Researchers argue that robust Australopithecines should be classified in a separate genus called Paranthropus.
Explanation: The "robust" australopiths are a group of fossil hominins that existed in East and southern Africa between approximately 2.5 and 1.4 million years ago (Ma). They are referred to here as members of the genus Paranthropus, though considerable disagreement about their proper taxonomy persists. (credit to the internet)

Some fossil snakes have remnants of hip bones and legs even though these animals had no legs. These remnant structures are best described as: vestigial structures.
Vestigial structures are organic structures that do not appear to fulfill any important biological function in the organism that possesses them.
These structures are preserved as an inheritance of the evolutionary process, because at some point in the history of evolution an ancestor of the current species had that structure.These types of structures, which can be bones, organs, structures in the skin or any other part of the body, no longer offer any meaningful function for the body.The presence of vestigial structures in animals is considered proof that evolution and natural selection exists.
Therefore, we can conclude that some fossil snakes have remnants of hip bones and legs even though these animals had no legs. These remnant structures are best described as vestigial structures.
