A group of students were debating whether unicellular bacterial cells that reproduce using the process of binary fission are actually performing mitosis and meiosis. Select the student with the best argument.
Poppy: A bacterial cell is going to undergo mitosis so that it can create offspring with double the number of chromosomes. The offspring with the double amount of chromosomes will then divide with mitosis creating four daughter cells with triple the amount of chromosomes.
Zabriya: The process of binary fission and meiosis are basically the same process with the same end result, a daughter cell with half the number of chromosomes. Unicellular organisms are not going to undergo mitosis because mitosis doubles the number of chromosomes.
Gauge: The process of binary fission is similar to mitosis because the results are identical cells, but binary fission always results in new identical organisms with the same chromosomes as the parent.Meiosis is not performed because the offspring would have half the number of chromosomes.
Dacy: A bacterial cell is going to do both mitosis and meiosis. The bacterial cell will divide using the process of mitosis and then it will divide again using meiosis creating four daughter cells with the same number of chromosomes as the parent bacterial cell.

what is the probability that a mother with type O blood and a father with type AB blood will have a child with type B blood
Answer:
So, without being given any more information (like that another child is already A, B, or O) then there are 16 possible combinations that can be had, but only one of them is type O, so there’s a 6.25% chance the child could be O.

4
O decomposition
sun
O combustion
O consumers
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.

the following phase of meiosis then put them in the correct order
Anaphase I , Metaphase II , Telophase l , Prophase l , Telophase ll / Cytokinesis ll
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

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.
We do not usually experience sensations directly.

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.

Skin cells form new cells to replace the damaged cells. What is the most important outcome of this process?
Mitosis is the process which is responsible for the replacement of old and damaged skin cells with new skin cells. This process is responsible for the formation of new cells which are similar to the parent cell.
What is Mitosis?Mitosis is the process of cell division wherein the chromosomal material of the cell replicate and get equally distributed into the two daughter cells. The chromosome number in each of the daughter cells produced is equal to that in the parent cell which is diploid (2n). Hence, mitosis is known as equational division.
The offspring or daughter cells produced through mitosis are similar to the parent cells and are called as clones. The mitotic division is divided into four main phases which include prophase, metaphase, anaphase, and telophase.

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.
The cell cycle is disrupted when there is an abnormal increase in the rate of mitosis. An

individual developing
A. O a type of cancer.
B.

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.
