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.

If the Pacific plate is moving at a speed of 5 centimeters per year, how many kilometers will the Pacific plate travel in 1 million years?
Answer: 50 kilometers
Explanation:
From the question, we are informed that the Pacific plate is moving at a speed of 5 centimeters per year. The number of kilometers that the Pacific plate will travel in 1 million years would be calculated as:
= 5 × 1,000,000
= 5,000,000 centimeters
Since 100000 centimeters = 1 kilometer, we would convert 5,000,000 centimeters to kilometers. This will be:
= 5,000,000 / 100,000
= 50 kilometers

I know one of the answers is that the lower temperature means the reaction will happen slower, but what’s the second answer?
Answer with Explanation:
Hydrogen peroxide is considered "unstable," thus, storing it in the refrigerator provides two advantages:
1. It slows down thermal decomposition.
The rate of decomposition slows down when the temperature is lowered. It increases when the temperature rises.2. It prevents photolytic decomposition.
Photolytic decomposition happens when hydrogen peroxide is exposed to sunlight or bright light. It therefore increases the rate of reaction. Therefore, hydrogen peroxide should be stored in a cool and dark place, such as the refrigerator.Will get brainliest answer
What occurs during the first stage of protein synthesis
1. The dna unzips, and rna bases match up along a strand.
2. Messenger rna moves out of the cell nucleus
3.transfer rna carries a specific amino acid to the ribosome.
4. Messenger rna attaches to a ribosome
Answer:
The correct answer is - 1. The DNA unzips, and RNA bases match up along a strand.
Explanation:
The first stage of protein synthesis is transcription, which is the process that copies DNA sequences in a complementary sequence into the new mRNA molecule. In this stage, DNA molecule unwinds and unzip, and RNA molecule bind at a strand and elongate by adding new complementary bases with the help of RNA polymerase enzyme. Once the elongation of the RNA molecule ends the termination takes place and a new mRNA molecule that stores information to synthesis amino acid chin is produced successfully.
Thus, the correct answer is - 1. The DNA unzips, and RNA bases match up along a strand.

drink fluids
Question
Question
by providing kind words, nurturing, and emotional support to the patients and asking them about
their feelings
Question
Answer:
A scientist's response to the increase in food poisoning sick patients should be examining the type and source within the foods consumed.
Explanation:
Food poisoning involves the effects that decomposed or contaminated food can have on a group of people who eat it, and can cause illness in all or most individuals.
Although patients' symptoms should be treated and preventive education provided, the best course of action for a scientist is to investigate the cause.
The response of a scientist to the increase in food poisoning cases is to determine the type and source of food, as well as the nature of the alteration it has -decomposition, contamination, bacteria- in order to eliminate the source and avoid new cases.
The other options may be valid in the face of the appearance of food poisoning cases, but they are not the best procedure with which a scientist would respond.What are some examples of unicellular organisms

Explanation:
I personally think it is D. Cause the kinetic energy(motion) is happening while the ball is move fast toward the catchers hand. Then when he catches it the ball stops moving and turns into potential energy(movement about to happen) cause the ball is not moving and the catcher has to return the ball back to who ever.

a. The question the students were trying to answer was "Which type of soil would rose bushes grow the tallest in?" Their hypothesis was that one type of soil would lead to the rose bushes growing taller than the others.
b. The independent variable in this experiment was the type of soil in which the rose bushes were planted. The dependent variable was the height of the rose bushes. They likely measured the height of the bushes at regular intervals (e.g. daily or weekly) using a ruler or tape measure.
The conditions (variables) that were controlled during the experiment were the size of the rose bushes, the size of the pots, the amount of water, the light and temperature conditions.
What is a variable?A variable is a characteristic or property that can take on different values or can be manipulated in an experiment or study. In science, variables are used to help understand the relationship between different factors or phenomena.
They can be classified as independent variables, which are manipulated by the experimenter, and dependent variables, which are observed or measured as a result of the manipulation of the independent variable. In some cases, there are also controlled variables which are kept constant in an experiment

What characteristic of water causes water to stick to the side of a test tube?
I need a claim, evidence, and reasoning ! will give brainlist
Answer:
The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity (Claim).
Explanation:
Water (H₂O) is a polar molecule with the ability to generate van der Waals forces, which is explained by the 4 hydrogen bonds it forms to bind to other substances. The consequence of the forces of the molecular bonds are four properties of H₂O, including surface tension, cohesion, adhesion and capillarity.
- Claim: The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity.
- Evidence: Cohesion and adhesion of water are properties that come from the forces of the molecular bonds of water, and whose effect is the ability of water to wet surfaces and adhere to a tube that contains it, the latter due to capillarity. Capillarity also allows water to rise through the roots and stems of plants, through their thin vascular ducts.
- Reasoning: cohesion in water depends on the force of attraction between H₂O molecules, adhesion is the capacity of H₂O molecules to join other different molecules and —together with surface tension— make H₂O molecules close to the walls of a glass tube adhere to it, which represents capillarity.
The effect of capillarity is more evident when the test tube is of a smaller diameter, although capillarity and adhesion to its walls always exist, and to a greater degree than any other substance.

Meiosis occurs in a series of different phases and creates genetically unique reproductive cells.
Which process helps make meiotic cells genetically different and occurs during prophase I, but not during prophase II?
fertilization
independent assortment
crossing over
chromosome replication
Answer:
Meiosis occurs in a series of different phases and creates genetically unique reproductive cells. The process which helps make meiotic cells genetically different and occurs during prophase I, but not during prophase II, is crossing over (C). Crossing over is the exchange of genetic material between two homogenous chromosomes. It is one of the final phases of prophase I. This process is called synapsis. It occurs when the matching regions on the matching chromosomes break and then reconnect to the other chromosome .
The process that helps to make meiotic cells genetically different and occurs during prophase I is called crossing over.
Crossing over, also known as recombination, is the interchange of genetic material between non-sister chromatids of homologous chromosomes.This process (crossing over) occurs in Meiosis I, specifically during Prophase I.Crossing over during Prophase I and the independent assortment of homologous chromosomes during Metaphase I represent meiotic processes that help to increase genetic variation in gamete (sex) cells.In conclusion, the process that helps to make meiotic cells genetically different and occurs during prophase I is called crossing over.

How can a diet that is 90% carbohydrates support the same amount of protein in the human body as a diet that is only 15% carbohydrates?
Answer:
Due to increase or decrease in the concentration of carbohydrates have no effect on protein concentration.
Explanation:
A diet having 90% carbohydrates support the same amount of protein in the human body as a diet that is only 15% carbohydrates because with the increase or decrease of carbohydrates in the diet does not increase the amount of protein. Protein and carbohydrates are two different things, proteins broken down into amino acid that is utilize by the body for making muscles while carbohydrates are broken down into glucose that is used by the body for performing daily activities.
90% carbohydrates support the same amount of protein in the human body as a diet that is only 15% carbohydrates as it helps to balance the amount of carbohydrates and protein needed for the body to perform its activities.
CarbohydratesBoth carbohydrates and proteins have a vital role in good health. Proteins in our body help to maintain healthy skin, bones, hair and muscles. Carbohydrates give energy to our body parts like the brain, kidney and heart to function properly.
If your diet has only 15% of carbohydrates, then the body will take any measure to get the energy it required for the proper functioning of body parts. The body tries to break down the proteins (that you eat)chemically until it act like carbohydrates.
