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.
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

Large bodies of water can cause areas to be __________ in the winter and __________ in the summer.
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.

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.

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.

Which colony of bacteria resemble that of fried egg؟
Answer:
Fried Eggs are a perfect source for bacterium to feed on. It provides Ovalbumin, ovotransferrin, and ovomucoid. But a conflict would happen becasue eggs have lytic, which takes action against baxteira, so if there is enough of them the bacteria could take over the lytic in the egg and have a great feast.
