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.

hydrogen gas + oxygen gas =
water. what is the product of the reaction
Answer:
Water
Explanation:
In chemical reactions, the atoms in the reactants are rearranged to form the products.
Reactants vs. Products
The reactants in a chemical reaction are the substances that you began with. The products are the result of the reaction.
For example, in the question, you are given hydrogen and oxygen. Then, through a chemical reaction, water is created. The reactants (hydrogen and oxygen) are the compounds that are changing to create the product (water).
Finding the Products
The order that a chemical reaction is written is important. Unlike equations in math, you cannot arbitrarily change the left and right. The left side of a reaction will always contain the reactants, while the right side has the products. Since water is on the right, water is the product.
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:

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.

mutants of arabidopsis with alterations in seed lipid fatty acid composition theoretical and applied genetics
The discussion of mutants of arabidopsis with alterations in seed lipid fatty acid composition theoretical and applied genetics is written in below paragraph-
By analyzing the fatty acid composition of samples of seed from 3,000 mutagenized lines, a rich variety of mutant Arabidopsis with different seed lipid compositions was discovered. Defects in the elongation of 18-1 to 20-1, desaturation of 18-1 to 18-2, and desaturation of 18-2 to 18-3 were caused by a series of mutations that were found. The wild type showed partial dominance over the mutant allele in each of these instances. These findings, in addition to findings from other studies, indicate a significant role for gene dosage in influencing the fatty acid content of seed lipids. A mutation that increased the accumulation of 183 was also discovered.
A broad variety of mutant Arabidopsis with various seed lipid compositions was found by examining the fatty acid composition of seed samples from 3,000 mutagenized lines. A number of mutations were discovered that were responsible for defects in the desaturation of 18-1 to 18-2, 18-1 to 18-2, and 18-2 to 18-3. In each of these cases, the mutant allele was somewhat dominant over the natural type. These results, together with those from previous studies, point to a significant role for gene dosage in affecting the fatty acid composition of seed lipids. Additionally, a mutation that increased the accumulation of 183 was found.

In lactic acid fermentation: Glucose --> pyruvate--> lactic acid

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.

If a cell that is composed of 60% water is placed in a solution that is 90% water, that means that the cell is ______% solute while the solution is ____% solute.
If a cell that is composed of 60% water is placed in a solution that is 90% water, that means that the cell is 40% solute while the solution is 10% solute.
The calculation can be made by the formula using,
Solute + Solvent = Solution
Solute- A substance that dissolves in a solution is referred to as a solute. In fluid solutions, the solvent content is greater than the quantity of solute.
Solvent- A material that can dissolve solutes, that are molecules and compounds, is referred to as a solvent.
Solution- The majority of life's chemistry takes place in aqueous solutions, or mixtures in which water acts as the solvent. A solution is a homogenous mixture of a solvent and a solute.

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 .

2) Quantitative data
These are further classified into four types of data: nominal, discrete, ordinal, continuous.
Quantitative data type tries to quantify things and does by considering numerical values that make it countable in nature. It includes statistical data analysis. These type of data are also known as "Numerical data". It answers the questions like, "how much", "how many", "how often".
Quantitative data can be used for statistical manipulation. These data can be represented on wide variety of graphs and charts such as bar graphs, pie charts, line graphs, histograms, etc.
