The blood Group of Mother is O. The Blood Group of the Child is B. Man Exonerated If He to Blood Group?
Answer:
If the mother's blood type is O, and the child's blood type is B, a man would be exonerated from paternity if he has blood type A or O.
Explanation:
In the above case, if a mother has blood type O and her child has blood type B, a man can be exonerated from paternity only if his blood type is A or O, and responsible if he is type B or AB.
The blood type is defined by the presence of surface antigens in the red blood cell, called A and B. The presence of each antigen is determined by a gene present on the parental chromosomes.
Blood type A corresponds to the presence of gene A, and its genotypic expression can be A/A or A/O. Type B blood, whose genotype is B/B or B/O, is due to the presence of a gene containing the B antigen. AB blood —due to codominance— has one gene for A and another for B, with genotype A/B. Blood type O, characterised by the absence of surface antigens, behaves like a recessive trait, which only manifests itself in the absence of surface antigens A and B. The genotype is O/O.By making a hypothetical crossing between mother and man, one can observe why he can be exonerated.
Man with blood type O
♂ O|O
♀ O|O
Alleles O O
O O|O O|O
O O|O O|O
The only possibility, in this case, is to have children with type O blood. No chance of children B.
Male with blood type A
♂ A|O
♀ O|O
Alleles A O
O A|O O|O
O A|O O|O
In this case there is a 50% chance that the children will be blood type A and 50% chance that they will be O. No chance of children B.
In the case of a man A|A the result is 100% probability of children A|O, and no probability of children B.
So, a man with blood types A (any genotype) and O, can be exonerated from paternity, since it is impossible for him to have a child of blood type B, when the mother is of blood type O.

Which set of items listed can be arranged to transform chemical energy into mechanical energy? A. motor, fan blades turning, wire
B. magnet, wire, fan blades turning
C. battery, wire, fan blades turning
D. battery, magnet, heat
Answer:
C
Explanation:
your welcome
The set of items which can transform chemical energy into mechanical energy is the battery, wire, fan blades turning. Thus, the correct option is C.
What is energy conversion?
Chemical energy can be converted into mechanical energy by the arrangement of batteries, wire, and fan blades turning. The chemical energy from the movement of ions in the wire causes the movement of fan blades and this turning is a form of mechanical energy.
In a combustion engine, chemical energy is first converted to heat energy that causes expansion of a fluid which results into motion. In contrast, the motor proteins are the molecules which can convert the chemical energy present in the molecules released from adenosine triphosphate (ATP) hydrolysis directly into useful mechanical work.
Therefore, the correct option is C.

During aerobic respiration, the energy within the bonds of a glucose molecule is released in small amounts in a step-by-step, enzyme controlled reaction. In this process, the energy released is used to
Answer: In this process, the energy released in form of ATP (Adenosine triphosphate) is used to POWER BIOCHEMICAL PROCESSES.
Explanation:
Aerobic respiration is the process by which living organisms breaks down glucose molecule to release energy. Oxygen is used for this process that's why the name aerobic.
Aerobic respiration releases energy within the bonds of glucose step by step in an enzyme controlled reaction. The stages of these processes includes:
--> Glycolysis: In this stage, glucose molecules are split to produce two molecules of ATP and two molecules of NADH (another energy carrying molecule).
--> Krebs Cycle: this is the second stage which occurs in the mitochondria of cells. The 2 ATP molecules generated from glycolysis is used to produce two more ATP, 8 more NADH and 2 molecules of FADH. This makes it a total of 16 energy molecules ( including 2 molecules of ATP from glycolysis).
--> Electron transport chain: this is the last stage of aerobic respiration which takes part at the inner member of the mitochondria. Electrons are transported from molecule to molecule down an electron-transport chain. Some of the energy from the electrons ( NADH and FADH from kreb cycle) is used to pump hydrogen ions across the membrane, creating an electrochemical gradient that drives the synthesis of many more molecules of ATP. As a result 32 more ATP are generated.
In conclusion, a total of up to 36 molecules of ATP from just one molecule of glucose in the process of aerobic respiration which are used to power biological processes.

The immune system is designed to protect against pathogens such as microscopic organisms and foreign substances that arise from outside the body
Answer:
True.
Explanation:
Protecting against pathogens such as microscopic organisms and foreign substances that arise from outside the body is the role of the immune system.
Answer:
true
Explanation:
Inside your body there is an amazing protection mechanism called the immune system. It is designed to defend you against millions of bacteria, microbes, viruses, toxins and parasites that would love to invade your body. To understand the power of the immune system, all that you have to do is look at what happens to anything once it dies. That sounds gross, but it does show you something very important about your immune system.
When something dies, its immune system (along with everything else) shuts down. In a matter of hours, the body is invaded by all sorts of bacteria, microbes, parasites... None of these things are able to get in when your immune system is working, but the moment your immune system stops the door is wide open. Once you die it only takes a few weeks for these organisms to completely dismantle your body and carry it away, until all that's left is a skeleton. Obviously your immune system is doing something amazing to keep all of that dismantling from happening when you are alive.

Demand of oxygen in water does not increase with increase in
a/concentration of solid waste
b/number of aquatic plants
c/number of aquatic animals
d/rapid flow of water
Answer:
b. number of aquatic plants
Explanation:
The number of aquatic plants doesn't increase the demand for oxygen in water because these plants take in carbon dioxide rather than oxygen. This means that an increase in their number will not trigger an increase demand for oxygen, rather it will trigger an increase demand for carbon dioxide in its dissolved form.
An increase in the concentration of solid waste, increases the demand for oxygen because it is needed for decomposition.
An increase in aquatic animals will increase the demand for oxygen in its dissolved form because aquatic animals take in oxygen to survive.
An increase in the flow of water increases the demand for oxygen because as water flows, it mixes with air. The more rapid it is, the higher the chance to mix with oxygen.

The DNA sequence that produced the mRNA sequence uracil, guanine, cytosine, guanine adenine uracil adenine adenine
Answer:
The DNA sequence that produced the mRNA sequence uracil, guanine, cytosine, guanine adenine uracil adenine adenine during transcription is adenine, cytosine, guanine, cytosine, thymine, adenine, thymine, thymine.
Explanation:
Transcription of DNA into messenger RNA (mRNA) is a process in which the specific nucleotide sequence is transferred from one molecule to another, through the synthesis of mRNA molecules from a DNA strand.
The complete transcription process is done by nitrogenous base complementarity, where mRNA receives the sequence of complementary bases according to the DNA sequence:
Adenine is complemented with uracil, since in RNA the thymine is substituted by this uracil. Thymine is complemented with adenine. Cytosine is complemented with guanine. Guanine is complemented with cytosine.Thus an uracil mRNA sequence, guanine, cytosine, guanine adenine uracil adenine U-G-C-G-A-U-A-A comes from a DNA sequence adenine, cytosine, guanine, cytosine, thymine, adenine, thymine, thymine or A-C-G-C-T-A-T.
