The cell cycle is disrupted when there is an abnormal increase in the rate of mitosis. An
abnormal and uncontrolled increase in the rate of mitosis is frequently associated with an
individual developing
A. O a type of cancer.
B.
into two or more organisms.
C.
only one sex cell.
D.
a single set of chromosomes.
Answer:
A
Explanation:
Cancer is the uncontrolled increase of cells, so when the rate of mitosis increases, so does the number of cells. This means A is the answer.
Uncontrolled cell growth is cancer. Gene mutations can increase the pace of cell division or suppress natural mechanisms that keep the body in check, like cell cycle arrest or programmed cell death. Thus, option A is correct.
What results, uncontrolled increase in the rate of mitosis?The cell's size, the presence of neighboring cells, and other chemical stimulators are three of the key elements in mitotic regulation.
Numerous mitogens are involved in regulating mitosis. Therefore, cell size, cell existence, and chemical stimulators are the proper answers.
When cancer cells develop in body tissues, they undergo aberrant cell growth patterns known as hyperplasia and dysplasia.
An increase in the quantity of cells in an organ or tissue that look normal under a microscope is known as hyperplasia.
Therefore, An abnormal and uncontrolled increase in the rate of mitosis is frequently associated with an individual developing cancers.

Explanation:
In recent years, people have become concerned over the loss of
ultraviolet rays from the sun.
because it protects the earth from damaging
1. Ozone
2. carbon dioxide
3. nitrous oxide
Answer:
1. Ozone
Explanation:
Ozone is a substance with the chemical formula, O3, found in the stratospheric part of the atmosphere. It functions to prevent the harmful ultraviolet (UV) radiation from the sun from reaching the Earth. However, due to anthropogenic activities i.e. human activities that releases greenhouse gases e.g. CO2, CFC etc. the protective function of the ozone layer is wavering.
Hence, based on this question, people are concerned over the fact that this OZONE layer is depleting, hence, risking the exposure to the harmful radiation from the sun.
For example, a friend of yours goes to the gym and takes a 30-minute, cardio interval training class. While switching between doing high-intensity push-ups, jumping jacks, and weight training, she notices that there is a burning sensation in her muscles. The burning is due to the buildup oflactate in the muscle tissue, a result of her muscles supplying ATPanaerobically . What is true about this pathway for forming ATP
Answer:
No oxygen is required.
Explanation:
This pathway for forming ATP needs no oxygen and the ATP that is produced are in very low concentration. The low amount of ATP production occurs when the cell goes for anaerobic respiration in which the cell produces less ATP. This type of ATP production occurs only when the body requires ATP quickly so that's why the body uses this type of respiration during exercise and running activities etc.
advantages and dis advantages of asexual reproduction in plants
Explanation:
Advantages Of the asexual reproduction
The organism that reproduces asexually has the ability to take many different extensive forms that allow asexual reproduction to succeed in various environments?
The asexual reproduction is only performed in the organisms that often stay in one place, It does not need mobility, So, most plants have a great ability to create their offspring as this process doesn’t need to move to another place.
Asexual reproduction has a rapid increase of offspring which is very helpful in producing lots of offspring, It lets the plants make lots of offspring effectively which will help them in increasing their genes.
Disadvantages Of Asexual Reproduction
Most organisms that only perform the asexual reproduction process have less chance to adapt to the changes of the environment as they need stable environments.
Only one parent plant is required for the asexual reproduction, the new plants are identical to the parent so that good features will always be passed on, the chromosomes and genes of the parent will be copied, So, there will be genetic defects or the mutation in the offspring with no exception.
The asexual reproduction does not have the genetic diversity, there is less variation produced with the offspring, and the organism becomes less adapted to certain environmental changes, the entire communities will not be adapted to the harsh environment.
The asexual reproduction usually leads to struggle for the existence as well as the overcrowding, and the main distinction of asexual reproduction from the sexual reproduction is that there is no need for two parents as well as special cells to reproduce.

A geneticist is trying to recreate a strand of DNA from a crime scene investigation. The strand of DNA recovered from the scene was 1800 bases long. The geneticist has determined that the strand contained 425 thymine
nucleotides. Based on this information, identify the number of cytosine nucleotides
Answer:
475
Explanation:
The strand is only made up of Adenine, Thymine, Cytosine and Guanine. There will be the same number of Adenine as there are Thymine and the same number of Cytosine as there are Guanine.
We know there are 425 Thymine. This means there are also 425 Adenine. Therefore, you would subtract 850 (425x2) from 1800 to find the amount of Cytosine and Guanine left, which is 950.
Out of the 950, half will be Cytosine and half Guanine. 950/2 is 475.

Answer:
B. Sun.
Explanation:
The carbon cycle can be defined as the cycle in which carbon atoms travel from the atmosphere to earth and back to the atmosphere. As carbon is the source through which all life on earth exists.
The source of the carbon cycle is solar energy. During the process of photosynthesis, it is the sun that plays an integral role in taking carbon dioxide from plants.
Therefore, option B is the correct answer.

Telophase ll , Prophase ll , Metaphase l
Answer:
The correct order is
Prophase l , Metaphase l, Anaphase I, Telophase l, Prophase ll, Metaphase II, Telophase ll / Cytokinesis ll
Explanation:
In Meiosis there are total two phases - Meiosis I and Meiosis II and each phase consists of total six sub phases which are as follows -
Meiosis I
1. Prophase I
2. Prometaphase I
3. Metaphase I
4. Anaphase I
5. Telophase I
6. Cytokinesis I
Meiosis II
1. Prophase II
2. Prometaphase II
3. Metaphase II
4. Anaphase II
5. Telophase II
6. Cytokinesis II
Hence the correct order is
Prophase l , Metaphase l, Anaphase I, Telophase l, Prophase ll, Metaphase II, Telophase ll / Cytokinesis ll

Many different types of mutations can occur within the body. Sickle cell anemia is a disease that occurs when a mutation in the base pair of the hemoglobin beta gene causes a single replacement of the amino acid glutamic acid by the amino acid valin. As a result of this mutation the individual’s blood cells take on a sickle shape under certain conditions Which type of mutation causes sickle cell anemia
Answer:
POINT MUTATION (SUBSTITUTION)
Explanation:
A point mutation is that mutation which involves only one nucleotide base. Point mutation can, however, occur in different ways such as SUBSTITUTION. Substitution point mutation is that which involves the replacement of a single nucleotide base by another in a gene sequence.
This is the case in this question regarding the mutation that causes sickle cell anaemia. According to this question, Sickle cell anemia is a disease that occurs when a mutation in the base pair of the hemoglobin beta gene causes a SINGLE replacement of GLUTAMIC ACID (Glu) by VALINE (Val). This shows that it is a type of SUBSTITUTION POINT MUTATION.
