Answer:

If a father has type A blood and the mother has type AB blood, they cannot have a child with blood type O, although depending on the father's genotype, they may not have children with a B blood type either.

Explanation:

Blood type is determined by the presence or absence of surface antigens A and B, which is genetically determined and establishes the pattern of inheritance.

Alleles that define the presence of antigens A and B are co-dominant, while the absence of antigens - as in blood type O - is a recessive trait.

The father with blood type A can have two genotypes, A|A or A|O, which raises 2 possible scenarios:

1. Father A|O with mother A|B

Alleles       A         O

A              A|A      A|O

B              A|B      B|O

In this case there is no chance of having a child with blood type O, 50% chance of having children with blood type A, 25% B and 25% AB.

2. Father A|A with mother A|B

Alleles        A        A

A               A|A     A|A

B               A|B     A|B

50% chance of having a child with blood type A and 50% with blood type AB. In this case there is no chance of having children with blood type O or B.

Answer:

b

Explanation:

The average speed of an object is the sum of the distance traveled by the object relative to the total time taken to cover the distance. In other words,

Average speed = total distance traveled/total time taken

In this case, the total distance traveled by the runner = 26.2 miles while the total time taken = 3 hours and 15 minutes

60 minutes = 1 hour

15 minutes = 0.25 hours, hence

3 hours 15 minutes = 3.25 hours

Average speed = 26.2/3.25

                          = 8.0615 miles/hour

                            = 8.1 miles/hour

B. Paternity

Explanation:

Edge 2020

The career that combines DNA technology and forensics is paternity testing. The correct option is B.

DNA testing examines an individual's DNA banding patterns to determine the identity or mutations of a specific gene.

Paternity testing is a type of DNA testing that is used to determine paternity and the true nature of a relationship.

The lab compares tissue samples from the mother, the child, and the man to determine what unique characteristics known as genetic markers the child shares with the mother and the man who may be the father.

The chromosomes that determine the gender of the baby (X and Y chromosomes). The mother's egg typically contributes an X chromosome, while the father's sperm contributes either an X or a Y chromosome.

These tests are extremely accurate in determining whether a man is the biological father of a child.

Thus, the correct option is B.

Answer:

C. active transport, because protein pumps are needed to move substances against a concentration difference

Explanation:

There are two major types of transport in living cells namely: passive transport and active transport. The passive transport moves molecules down a concentration gradient and hence, do not need energy (ATP) to occur. However, on the other hand, ACTIVE TRANSPORT moves substances against their concentration gradient, thus, require energy input.

Active transport makes use of PROTEIN PUMPS to achieve this process. Hence, in this case where Alexis is using models of the cell membrane to compare the types of cellular transport. The model that shows a molecule entering through a protein pump is modelling ACTIVE TRANSPORT.

The exerpt states that movements in the Earth's crust (unbalance) causes Earthquakes. When it's balanced, there is no plate movement.

Answer: c

Explanation: if there is no plate movement that means that there is a balanced force there is nothing that is disrupting it. but if there's an earthquake in that means that there are unbalanced forces in that they cause an earthquake. a force is balanced if the two individual forces are of equal magnitude and of the opposite direction. And an object is said to be acted upon by an unbalanced force when there is an individual force that is not being balanced by a force of equal magnitude and in the opposite direction.

The process of breaking bonds between molecules and the making or reforming of bonds encompasses chemical processes which allows the creation or formation of new molecules.

When bond is broken such that a certain element splits from a compound, new molecule is formed. Endothermic processes required energy to break bonds between atoms.

Bond making on the other hand are exothermic processes which involves merging of bond accompanied by the release of energy to form new molecules.

Therefore, bith Endothermic and exothermic processes allows cells to make new molecules.

Answer:

The correct answer is - B. the chemical properties of the peptide bonds.

Explanation:

The difference between the structures of catalase from other proteins depends on the chemical properties of the peptide bonds present in between the amino acids which decide the pH and temperature by their disruption. These bonds present between two alpha-amino acids when carboxyl of one amino acid interacts with the amino group of the other to form an amide-type covalent bond.

Answer:

Being that the moon has a gravitational force of 1.622m/s 2, we multiply the object's mass by this quantity to calculate an object's weight on the moon. So an object or person on the moon would weigh 16.5% its weight on earth. Therefore, a person would be much lighter on the moon. Conversely, a person is 83.5% heavier on earth than on the moon.

Explanation:

hope this helps you out love!! <3

Answer:

weight of objects on EARTH> weight of objects on MOON

Explanation:

weight= mass * gravity

assuming both objects have the same mass, the environment with greater gravity will result in a greater weight

gravity of earth > gravity on the moon

so

weight of objects on EARTH> weight of objects on MOON
