gene essentiality profiling reveals gene networks and synthetic lethal interactions with oncogenic ras
There are several genetic variations among human malignancies. Here, we catalogue this variability and make use of it to find gene connections that function and cancer-related risks that are genotype-dependent. We create a gene essentiality dataset across 14 human acute myeloid leukaemia (AML) cell lines using genome-wide CRISPR-based screens.
What is a gene ?The term "gene" has a variety of meanings in biology. The molecular gene is a sequence of nucleotides in DNA that is transcribed to form a functional RNA, whereas the Mendelian gene is the fundamental unit of inheritance.
Protein-coding genes and noncoding genes are the two different categories of molecular genes. While type III genes are involved in cell-to-cell signalling and type II genes are a complicated combination of all three types, type I genes often function as immune response or sensory receptors.Learn more about Gene here:

How many variations do you observe?
Answer:
Variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation). Variation may be shown in physical appearance, metabolism, fertility, mode of reproduction, behaviour, learning and mental ability, and other obvious or measurable characters.
chromosomes or by differences in the genes carried by the chromosomes. Eye colour, body form, and disease resistance are genotypic variations. Individuals with multiple sets of chromosomes are called polyploid; many common plants have two or more times the normal number of chromosomes, and new species may arise by this type of variation. A variation cannot be identified as genotypic by observation of the organism; breeding experiments must be performed under controlled environmental conditions to determine whether or not the alteration is inheritable.
Genotypic variations are caused by differences in number or structure of Environmentally caused variations may result from one factor or the combined effects of several factors, such as climate, food supply, and actions of other organisms. Phenotypic variations also include stages in an organism’s life cycle and seasonal variations in an individual. These variations do not involve any hereditary alteration and in general are not transmitted to future generations; consequently, they are not significant in the process of evolution.

14. Write a flow chart for any one type of fermentation, starting from Glucose -------- to
lactic acid or alcohol and CO2.Mention in between steps.
Answer:
In lactic acid fermentation: Glucose --> pyruvate--> lactic acid
Explanation:
Some organisms produce their own chemical energy supply, or they may ingest organic substances like glucose and absorb energy. Such species may produce energy provided by producers.
Without the presence of oxygen, they break down chemical energy from glucose by lactic acid fermentation in their cytoplasm.
Within Glycolysis:
In order to break up glucose into 2 molecules of pyruvate, 4 ATP and 2 electrons holding NADH molecules, 2 molecules of ATP are used. Since 2 ATPs are used, this process generates a net 2ATP.Then...
Pyruvate is then converted to lactic acid, forming 2 NAD+s, which are used as electron carriers.After 8 hours of sleep and before eating, which hormone will be secreted and what cells secreted it?
Answer:
a.
Explanation:
After 8 hours of sleep and before eating the hormone that will be secreted is and the cell secreting it is : (A) I and IV i.e. Insulin and Beta cells
After waking up from 8 hours of sleep the body might become hungry therefore before eating and just after sleeping for a long time the hormone that will be secreted is the "hunger " hormone known as the Ghrelin which is produced in the stomach.
Ghrelin hormones modulates the secretion of insulin and Insulin receptor signalling in the beta cells of the pancreas. Therefore the hormone that will be secreted after long sleep and before eating is Insulin.
Hence we can conclude from the table attached that After 8 hours of sleep and before eating the hormone that will be secreted is and the cell secreting it is : (A) I and IV i.e. Insulin and Beta cells .

In the most general terms, the study of sensation and perception is called psychophysics, a term that was first coined by ________.
In the most general terms, the study of sensation and perception is called psychophysics, a term that was first coined by Gustav Theodor Fechner.
In the field of science, psychophysics can easily be described as a combination of stimulus and sensation as these two terms are often considered to be one, but are different. The branch of psychophysics combines the branch of psychology with the branch of physics.
The term 'psychophysics' first came forward by Gustav Theodor Fechner. He was a well-established person in the field of psychology as well as physics. The reason behind bringing the concept of psychophysics, according to Fecher was that the relation between stimuli and sensation needs to be understood.
Over time, the complex ways in which the mind of a person, and its perception relates to the stimuli are studied under the complex branch of psychophysics.

A man with type AB blood is married to a woman with type O blood. They have two natural children, and one adopted child. The children's blood types are: A, B, and O. Which child was adopted?
The adopted child will have a type O blood group despite the fact that the mother has type O, the father will pass on an A or a B allele to the children. These are dominant alleles.
What are blood groups?Blood groups are divided into four categories: A, B, AB, and O. The presence or absence of two antigens on the surface of red blood cells determines each one.
A and B are the names of these antigens. Type A blood is defined by the presence of antigen A on red blood cells. Type B blood is defined by the presence of antigen B on red blood cells. You have type AB blood if both antigens (A and B) are present on your red blood cells.
And if neither antigen (A or B) is present on your red blood cells, you have type O blood.
Thus, we can conclude that the adopted child blood group will be O.

What is Motion?
Motion is defined as when an object changes its position with respect to time. In other words, the act of moving or the process of being moved. It can be described in many words such as displacement, distance, velocity, acceleration, speed etc.
The motion in a long line or a curve is called as Translation whereas the motion which changes the orientation of the body is called Rotation. In both the cases, all the points in the body have same velocity (having speed with direction) and same acceleration which is defined as time rate of change of velocity.
Motions are of two types:
1. Translation
2. Rotation
Some examples of motions are running, cycling, swimming, eating, drinking etc. Motion is caused by force, when we apply a force motion occur.
Thus, the motion of the block is decreasing with the period of time. So, the correct option is (J).

which term is used to describe an animal's ability to survive if the cells are exposed to a hypotonic or hypertonic environment?
The term osmoregulation is used to describe an animal cell's ability to survive if in a hypotonic or hypertonic environment.
What is a hypotonic environment? A solution whose concentration is less than that of another solution is called as hypotonic solution. If a cell placed in a hypotonic solution, then water enters into the cell by the process of endosmosis and the cell becomes turgid or swollen. What is a hypertonic environment? A solution whose concentration is more than that of the another solution is called as hypertonic solution. If a cell placed in a hypertonic solution, water comes out of the cell by the process of exosmosis and the cell becomes flaccid or shrinks up. What is osmoregulation? It is a process which helps in regulating the osmotic pressure and the fluid-electrolytic balance in a cell.Osmo-receptors can detect changes in the osmotic pressure. Warm-blooded organisms and humans have their osmo-receptors in the hypothalamus. Osmo-regulators are also found in kidney.Hence, the correct answer is osmoregulation.
