If the mother's blood group is O and the father's blood group is AB, then the child's blood group could be A or B. Hence, Will could be his father.
What is blood group?Blood types are based on the presence or absence of specific antigens, which are chemicals that, if they are foreign to the body, may cause an immunological reaction.
Safe blood transfusions depend on proper blood typing and cross-matching since some antigens can cause a patient's immune system to attack the transfused blood.
In case of an emergency, it is crucial to know your blood type. You'll need compatible blood if you ever find yourself in a position where you need a blood transfusion. Blood cells can cluster together due to an incompatible blood group, which can be lethal.

The uterus is a hallow and flattened muscular organ that is the home to developing fetus.It is divide into three parts:fundus, body, and cervix.
Its functions are:
1.to regulate menstural cycle throughout the reproductive period.
2.to pass the sperms towards fallopian tubes for fertilization.
3.to provide site for embedding zygote.
4.to expel fetus through cervix at the time of birth.
Answer:
1. uterus is also known as the womb.
2.it helps to form a child (that is inside the womb) when the sperm is disposed inside the womb
For the following question, match the key event of meiosis with the stages listed below. I. Prophase I V. Prophase II II. Metaphase I VI. Metaphase II III. Anaphase I VII. Anaphase II IV. Telophase I VIII. Telophase II Centromeres of sister chromatids disjoin and chromatids separate.
Answer:
VII. Anaphase II
Explanation:
During metaphase II, fibers of the spindle apparatus drive chromosomes to the cell equatorial plane, where they line up. Sister chromatids are holden together until they reach Anaphase II, during which specialized enzymes break the bonds between chromatids and separate them. Each chromatid migrates to one of the poles. In telophase II, the new chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole
A transmembrane protein has the following properties: it has two binding sites, one for solute A and one for solute B. The protein can undergo a conformational change to switch between two states: either both binding sites are exposed exclusively on one side of the membrane or both binding sites are exposed exclusively on the other side of the membrane. The protein can switch between the two conformational states only if both binding sites are occupied or if both binding sites are empty, but cannot switch if only one binding site is occupied. What kind of protein do these properties define
Answer:
The protein is a symport protein.
Explanation:
Transport proteins are proteins which are involved in the transport of solutes across the cell membrane. The binding of the solute to be transported across the membrane causes a conformational change in the shape of the protein, thereby moving the molecule to the side of nthe membrane it is to be transported. The difference in the concentration of the solute across the membrane known as concentration gradient is mainly responsible for the transport of molecules by the transport proteins.
There are three types of transport proteins: uniport, symport and antiport transport proteins.
Uniporters are involved in moving only one molecule across a membrane
Symporters are involved in moving two or more molecule across a membrane in the same direction.
Antiporters are involved in moving two or more molecule across a membrane in opposite directions.
From the description of the transport protein in the question, both solutes A and B are moved across the membrane simultaneously in the same direction. Therefore, the protein is a symport protein.

Certain species of blind fish living in perpetual darkness in the ocean depths have evolved from ancestors that could see. Research indicates that the brain centers for vision in these fish is degenerating, whereas the brain centers controlling other senses are enlarging. What might be the MOST probable reason for the loss of vision in these fish
Answer:
Explanation:
Evolution for lack of light. If there is no reason for it you lose the ability but it strengthens other senses. It's compensation. The need to tell if the temperature has increased because of something nearby or ability to feel miniscule movement will increase to compensate for that lack of sense.
Sickle cell disease is a recessive trait which causes a deformation in red blood cells due to a mutation in the gene that codes for hemoglobin. Consider a father and a mother BOTH with the genotype Hh, where H is the normal hemoglobin gene, and h is the gene that codes for the defective hemoglobin. What percent of their children will have the genotype hh, which means they will have the full-blown disease?
Answer: Sickle cell disease is caused by a mutation in the hemoglobin-Beta gene found on chromosome 11. Hemoglobin transports oxygen from the lungs to other parts of the body. Red blood cells with normal hemoglobin (hemoglobin-A) are smooth and round and glide through blood vessels.
Explanation:
how do you think a new community begins in an area?
Answer:
community means an interacting group of various species in a common location. communities exist but new community can cause due to certain pressures either favored by the environment/nature or by humans/simply animals.
Undergoing pressures can can cause for selections such as,
-stabilizing selection
-directional selection
-disruptive selection
or may also occur due to mutations (naturally or manmade) that will further cause for a genetic drift so the nature/ the environment will help/ favor for the best fitting species to survive resulting for an evolution and will build up a new community.

Calculate the angle of impact for a blood droplet whose width is 6.8 mm and length is 7.2 mm.
1.)94°
2.) 16°
3.) 1°
4.) 71°
Answer:
71°
Explanation:
To obtain the angle of impact :
The length of blood stain = hypotenus
The width = opposite
Hence,
Hypotenus = 7.2 mm ; Opposite = 6.8mm
Angle of impact, θ = sin^-1(opposite /hypotenus)
θ = sin^-1(6.8/7.2)
θ = 70.8°
θ = 71°

The theory of endosymbiosis is based on Multiple Choice similarities between chloroplasts and other organelles in animals. evidence from the fossil record. the knowledge that ribosomes are structures found in bacteria, plants, and animals. the experiments in which bacteria were made to grow in plant cells forming chloroplasts. the observations that chloroplasts and mitochondria resemble bacteria.
Answer:
the observations that chloroplasts and mitochondria resemble bacteria
Explanation:
The Endosymbiotic Theory is a theory that enables us to understand the origin of eukaryotic cells. The Endosymbiotic Theory posits that the mitochondria and chloroplast, which are organelles found in the eukaryotic cells, were once prokaryotic microbes that were first ingested by amoeba-like organisms and subsequently evolved by developing a symbiotic relationship with them. Some of the most important lines of evidence that supports this theory are: 1-chloroplasts and mitochondria resemble prokaryotic cells, i.e., they have a similar size, replicate by binary fission and there are unicellular eukaryotic protists that have filamentous temperature-sensitive proteins at their division plane (similarly to bacteria), and 2- chloroplasts and mitochondria are organelles with their own DNA and their own ribosomes (which are similar to those of bacteria).
Answer:
the observations that chloroplasts and mitochondria resemble bacteria
Explanation:
Replication. Mitochondria and chloroplasts make more of themselves in much the same way as bacteria reproduce. ... Like bacteria, mitochondria and chloroplasts grow in size, duplicate their DNA and other structures, and then divide into two identical organelles.
Hemochromatosis is an inherited disease caused by recessive allele. If a woman and her husband, who are both carriers, have three children, what is the probability of all three children having a normal phenotype
Answer:
27⁄64
Explanation:
A recessive disease is expressed only when an individual carries two copies of the recessive allele (i.e., individuals must be recessive homo-zygous to suffer from the disease). In this case, both parents are carriers for hemochromatosis, i.e., both are heterozygotes carrying the defective allele, thereby the probability of having a child with a normal 'dominant' phenotype is 3/4, i.e., 3/4 individuals are expected to have an A_ genotype (1/2 AA + 1/4 Aa = 3/4), and 1/4 individuals are expected to have an aa genotype (where 'A' is the dominant allele and 'a' is the recessive allele associated with hemochromatosis). In consequence, the probability of having three children with the normal phenotype is 3/4 x 3/4 x 3/4 = 27/64.

A grass has four times the relative growth rate of a tree. But it only has double the photosynthetic rate. Please explain why the grass has such a higher RGR.
Answer:
Specific leaf area.
Explanation:
The grass has a higher relative growth rate as compared to trees because of Specific leaf area. The grass has higher growth rate due to their higher rate of photosynthesis which leads to more biomass production as compared to trees which takes too much time. The grass is able to grow faster due to environmental suitability or in other words, grasses has the ability to perform photosynthesis in every season and environment which the tree can't.
An enzyme that breaks DNA, dispels the tension, and reseals the strand ahead of a DNA replication growing fork is called a(n):
Answer:
Topoisomerase
Explanation:
Topoisomerases are enzymes that produce changes in the topology of the DNA during replication, transcription, traduction, or reparation processes. They can cut one or both strands and in order to relieve torsional stresses in the supercoiled structure of DNA. With this, they help to maintain the chromosome's integrity. There are two types of topoisomerases: topoisomerase I (it cuts only one strand of DNA) and topoisomerase II (it is able to cut both strands of DNA).
