Huntington's disease is an inherited autosomal dominant disorder that can affect both men and women. Imagine a couple has had seven children, and later in life, the husband develops Huntington's disease. He is tested and it is discovered he is heterozygous for the disease allele, Hh. The wife is also genetically tested for the Huntington's disease allele, and her test results show she is unaffected, hh.
What is the percent probability that the first child of this couple will have Huntington's disease?
probability: %
What is the percent probability that four of the seven children will have Huntington's disease?
probability: %
1. The percent probability that the first child of the couple will have Huntington's disease is 50%
2. The percent probability that four of the seven children will have Huntington's disease is 6.25%
Genetical probabilitiesThe disease is autosomal dominant. Only one dominant allele is needed for the disease to be manifested.
The husband is Hh and the wife is hh.
Hh x hh
Hh Hh hh hh
Hh (affected) = 1/2
hh (unaffected) = 1/2
1. Probability that the first child of this couple will have Huntington's disease is the same as the probability of having the disease. Thus, it is 1/2 (50%)
2. Probability that four of the seven children will have Huntington's disease is the same as the probability of having the disease in 4 places.
1/2 x 1/2 x 1/2 x 1/2 = 1/16 or 6.25%

The gummy bear osmosis lab report
The Gummy Bear has a covering that is selectively permeable, allowing water molecules to pass through but blocking bigger molecules. Water molecules migrate into the bear in this osmosis experiment, expanding it.
A gummy bear is a solute, and water molecules are a solvent when you mix them together. Water now enters the gummy bear by osmosis because it doesn't already have any (remember that water was eliminated when the bear was formed). because the salt water contains more salt molecules than the gummy bear. The Gummy Bear gets bigger and smaller.

Which best explains enzyme specificity?
O An enzyme is able to react with many different substrates
O An enzyme works best at certain pH
O An enzyme works best at a certain temperature
O An enzyme is only able to react with one substrate
The correct placement of side-chain functional groups that interact with the charged groups of the new substrate is necessary to change an enzyme's selectivity. In order for the functional groups to be positioned correctly, this necessitates sequence alterations that not only add the new functional groups but also modify the structure of the protein backbone. We present a computational design approach for the targeted modification of loops close to the active site to introduce unique enzyme-substrate interactions. The approach can restore native loop lengths and, frequently, native loop conformations, according to benchmark studies on 8 native protein-ligand complexes. Next, we redesign a crucial loop in human guanine deaminase using the technique to ensure that an important side-chain contact is made with the substrate ammelide.

Answer:
I'm pretty sure it is c or a
Forces in earths crust pulling apart the two slabs of rock, this force is called Tension. Therefore, option (A) is correct.
Earth's crust tension pulls rock apart. At divergent plate borders, tectonic plates move apart. Faults form when tensional forces strain and thin rocks when plates separate. These faults can create rift valleys, mid-ocean ridges, and other geologic features.
Seafloor spreading and continental rifting are driven by tension. As plates separate, magma from the mantle rises to build new crust. New crust is formed at mid-ocean ridges. Tensional forces can also cause continental rifting and ocean development. Tension forms Earth's crust and moves tectonic plates. Therefore, option (A) is correct

why is the earths atmosphere likened to a greenhouse?
Answer:
That's because the glass walls of the greenhouse trap the Sun's heat. The greenhouse effect works much the same way on Earth. Gases in the atmosphere, such as carbon dioxide, trap heat similar to the glass roof of a greenhouse. These heat-trapping gases are called greenhouse gases. earth's atmosphere is like the glass in a greenhouse because sunlight streams through the atmosphere and heats the Earth. As the heat radiates up from the Earth's surface, some escapes into space. The rest of the heat is absorbed by gases in the troposphere and warms the air.Greenhouse gases include carbon dioxide, methane, nitrous oxides, and water vapor. (Water vapor, which responds physically or chemically to changes in temperature, is called a "feedback.") Scientists have determined that carbon dioxide's warming effect helps stabilize Earth's atmosphere.greenhouse gases in the atmosphere absorb some infrared radiation and re-reflect it back to earth. 6. This causes the green house effect and results in an increase in average mean temperatures on earth.Greenhouse gases include carbon dioxide, methane, nitrous oxides, and water vapor.

Questions
1. What happens when the vertical angulation is steep (+70°)? Is the shadow shorter or longer?
2. What happens when the vertical angulation is flat (+20°)? Is the shadow shorter or longer?
How does this relate to distortion?
The correct answers are shorter, longer, and have inverse proportionality and are used in dental radiography.
In the first case vertical angulation is what is used to control the length of any image which is being recorded and it is dictated by the holding device which directs the beam of x-ray perpendicular to both the receptor and teeth and in this case the image which is formed is shorter then the real teeth and it also occurs if the central ray is directed perpendicular to the plane of the receptor rather than to the imaginary bisector.
In the second case, the vertical angulation is flat or if it is too small the image of the teeth will be longer than the actual teeth and it often occurs due to bisecting technique.
Distortion is any kind of change that can occur in both the shape and size of the object and this is inversely proportional to the vertical angulation as when vertical angulation is not correct it creates distortion and also the steep is angulation the smaller the image will be and flat the angulation is the larger or longer the image is and in distortion which comes due to radiograph is mainly used for the teeth and the recommended angulation is +10 degree in which the central ray is directed through the contact of the teeth.
This is also called dental radiography.

all chemical processes which take place in living cells ??
Biochemical reactions are chemical processes that occur within living organisms.
Chemical processes known as "biochemical reactions" happen within the cells of living beings. The study of biochemistry shows that understanding both chemistry and biology is necessary to comprehend how cells function in living things at the level of the organism. Metabolism is the collective term for all biological processes that occur within an organism. Both exothermic and endothermic reactions are a part of it.
Catabolic reactions are exothermic processes that occur within living things. These processes disassemble molecules into smaller parts while also releasing energy. The breakdown of glucose is an illustration of a catabolic reaction, which releases the energy required by cells for their vital functions. Anabolic reactions are endothermic processes that occur within living things. These processes combine tiny molecules into larger ones.
A biochemical reaction is the transformation of 1 molecule to a one-of-a-kind molecule inside a mobile. Biochemical reactions are mediated through enzymes, which might be biological catalysts which could alter the rate and specificity of chemical reactions internal cells.
Photosynthesis, gluconeogenesis (synthesis of glucose from non-carbohydrate resources, specifically used by the brain), protein biosynthesis, fatty acid synthesis, glycolysis, Krebs cycle, urea cycle, glycogenolysis are some common examples of biochemical reactions.
