Three alleles, A, B, and O, govern human blood typing. Alleles A and B are codominant with each other, and both are dominant to type O. A second gene affecting blood type is Rh-factor, which gives the blood a plus (+) or a minus (-). The Rh+ allele is dominant to the Rh- allele. What would be an expected phenotype of a cross between a woman who has AB blood and is Rh+ to a man who has O blood and is Rh-?
A. The offspring could be B-
B. The offspring could be A+
C. The offspring could be O-
D. The offspring could be AB+
Answers
The expected phenotype of a cross between a woman who has AB blood and is Rh+ (genotype: AB+/ABRh+) and a man who has O blood and is Rh- (genotype: OO/O- Rh-) would be: D. The offspring could be AB+
Since the woman has AB blood type, she has both the A and B alleles. The man has O blood type, which means he has two copies of the O allele. When these two individuals have offspring, there is a possibility for the child to inherit an A allele from the mother and an O allele from the father, resulting in blood type A. Similarly, the child could inherit a B allele from the mother and an O allele from the father, resulting in blood type B. Since alleles A and B are codominant, the child could also inherit both A and B alleles, resulting in blood type AB.
Regarding the Rh-factor, the woman is Rh+ (positive) while the man is Rh- (negative). The Rh+ allele is dominant over the Rh- allele. Therefore, any offspring that inherit the Rh+ allele from the mother would have a positive Rh-factor.
So, the expected phenotype for the offspring of this cross could be AB+ (blood type AB with Rh+).

2. explain the role of stomach in digestion. include all gastric hormones and enzymes released and their role in digestion .
Answers
The stomach is a vital organ in the digestive system. It is a hollow bag-like organ present at the left in the abdominal cavity. It has a wide role in the process of digestion-
The primary function of the stomach is to store food for several hours.About 10% of ingested protein is broken down completely in the stomach. The enzyme pepsin facilitates the later digestion of protein by breaking protein into peptone.The stomach maintains a low pH which is necessary for carbohydrate digestion.Fat digestion in the stomach is minimal due to the restriction of gastric lipase activity to triglycerides containing short-chain fatty acids.The presence of food in the stomach reflexly stimulates the secretion of pancreatic juice and the expulsion of bile.The HCl present in gastric juice kills bacteria and other harmful substances.Hormones control various digestive enzymes secreted in the stomach and intestines during the process of digestion and absorption. For example, the hormone gastrin stimulates gastric acid secretion in response to food intake. The hormone somatostatin stops the release of stomach acid.

describe two ways that primary producers produce high-energy compounds
Answers
Answer:
Photosynthesis uses energy from sunlight, and chemosynthesis uses chemical energy.
Explanation:
Two ways that primary producers produce high-energy compounds are Photosynthesis and chemosynthesis.
Primary producers, additionally called autotrophs, are unit creatures that acquire their ingredients from dead sources and their energy from daylight.
Plants and different living things use a method known as chemical action to remodel lightweight energy into energy which will then be free through respiration to power the organism's activities.
By mistreatment chemicals as their energy supply instead of daylight, bacterium turns out food (glucose) through a method called synthesis. Around hydrothermal vents, synthesis takes place, and gas seeps into the deep ocean wherever daylight isn't a gift.

middle which diagram shows the changes in appearance of a plant cell when a remains in a concentrated sugar solution for thirty minutes? what is th answer
Answers
The osmosis diagram is the one that most accurately represents how a plant cell might change in appearance after spending thirty minutes in a concentrated sugar solution.
Osmosis is the process by which water molecules move from an area with a lower concentration of solutes to an area with a higher concentration of solutes across a semi-permeable membrane.
If a concentrated sugar solution were present, the solute concentration outside the plant cell would be higher than that inside.
Water from inside the plant cell would naturally try to exit the cell as it is submerged in the concentrated sugar solution in an effort to balance the solute concentration on either side of the cell membrane.

sunlight is made in to a chemical energy using chlorophyll. Then uses energy to convert co2 and water in to glucose.
Photosynthesis is the process by which plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose (a type of sugar) and oxygen. This process occurs in the chloroplasts of plant cells.
Here is a step-by-step explanation of the process of photosynthesis:
1. Light Absorption: Chlorophyll, a pigment found in chloroplasts, absorbs sunlight. This light energy is essential for photosynthesis to occur.
2. Conversion of Light Energy: The absorbed light energy is used to power a series of chemical reactions that convert carbon dioxide and water into glucose. This process is called the light-dependent reaction.
3. Production of ATP and NADPH: During the light-dependent reaction, energy is stored in the form of ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate). These molecules act as energy carriers in the next step of photosynthesis.
4. Carbon Fixation: The ATP and NADPH produced in the light-dependent reaction are used in the Calvin cycle, also known as the light-independent reaction or the dark reaction. In this step, carbon dioxide is converted into glucose using the energy stored in ATP and NADPH.
5. Release of Oxygen: As a byproduct of photosynthesis, oxygen gas is released into the atmosphere. This oxygen is essential for the survival of many organisms, including humans.
Overall, photosynthesis plays a crucial role in the Earth's ecosystem by providing oxygen and producing food for organisms. It is an essential process that sustains life on our planet.

Answers
A reaction that uses the absence of hemolysis of red blood cells to indicate an antigen-antibody reaction is called a complement fixation reaction.
Complement fixation is a diagnostic test that is commonly used to detect the presence of antibodies or antigens in a patient's serum. The test involves adding a known antigen to a patient's serum and then adding a source of complement, which is a group of proteins that are involved in the immune response. If the patient has antibodies to the antigen, the antibodies will bind to the antigen and activate the complement system. One of the consequences of complement activation is the lysis, or destruction, of red blood cells. Therefore, if there is no hemolysis of red blood cells, it indicates that there was no antigen-antibody reaction and the complement system was not activated.

If you are going to allow a population of mice to randomly mate for 5 generations and you want to limit inbreeding to a maximum of 14.678481% after generation 5 (assuming you started with zero inbreeding), how many males do you need if you have 20 females?
a) 5
b) 10
c) 50
d) 2
e) 8
Answers
The answer is (b) 10. To limit inbreeding to a maximum of 14.678481% after 5 generations, we need to calculate the expected amount of inbreeding in each generation and then adjust the number of males to add to the population accordingly.
The expected amount of inbreeding in each generation can be calculated using the formula:
Expected inbreeding = (1 - (1/2)^(generation/2)) * (1 - (1/2)^(generation/2)^2) * ... * (1 - (1/2)^(generation/2)^(14))
Substituting the value of generation=5 gives:
Expected inbreeding = (1 - (1/2)^5) * (1 - (1/2)^5)^2 * ... * (1 - (1/2)^5)^(14)
= 0.81924005762932
The maximum amount of inbreeding allowed is 14.678481%. Substituting this value gives:
Maximum inbreeding = 14.678481 / 0.81924005762932
= 17.5937535396166
Therefore, to limit inbreeding to a maximum of 14.678481% after 5 generations, we need to add at least 17.5937535396166 males to the population.
Solving for the number of males needed if we have 20 females, we get:
17.5937535396166 = (20 * 1 - 14.678481) / 20
= 3.45344278981875
Rounding to the nearest whole number, we get:
The number of males needed is 3.
Therefore, the answer is (b) 10.

Photosynthesis is the process by which plants use light energy to convert water and carbon dioxide into sugars and oxygen. During photosynthesis, light energy is absorbed by the plant and converted into chemical energy. The water and carbon dioxide are broken down into their component parts, and the oxygen is released into the atmosphere. The sugars are stored in the plant for later use. The equation for photosynthesis can be represented as light energy + water + carbon dioxide → sugars + oxygen.
