Answer:
C
Explanation:
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.

how do the weight of objects on earth compare the weight of the objects on the moon why do you think this is
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

In plants, yellow pea color (Y) is dominant over green pea color (y). Two heterozygous plants (Yy) are crossed. Which of the following results supports Mendel’s Laws
1.All of the yellow offspring are heterozygous for color.
2.all of the offspring have genotype Yy.
3.All of the offspring are yellow.
4. The offspring could be yellow or green.
Answer: .All of the yellow offspring are heterozygous for color.
Explanation: do your chart
The offsprings could be yellow or green since the genotypes obtained after cross will be YY, Yy and yy Therefore, option (4) is correct.
What are Mendel' law?The following is an outline of Mendel's laws of inheritance:
The principle of dominance is the foundation of the laws of inheritance. The law specifies that hybrid offspring will only inherit the dominant phenotype. The alleles that do not show in an individual are referred to as recessive traits, whereas the alleles that do manifest are referred to as dominant traits.
The alleles for each gene separate from one another during the process of gamete creation, ensuring that each gamete carries just a single copy of each allele for the genes that it contains. This is known as the law of segregation.
The law of independent assortment states that genes for various characteristics might segregate in an unrelated fashion while gametes are being formed.

Clostridium Difficile (C. difficile) is a type of bacteria that increases its activity with most antibiotic use, and is therefore very difficult to treat. Research shows that the most effective way to prevent the spread of infection is frequent handwashing. However, many people have flat-out refused to wash their hands in hospitals. The government is contemplating passing a policy to make it mandatory for people entering hospitals to wash their hands or else risk not being seen by doctors and being escorted out of the building against their will. Do you think the government should go ahead with this plan?
Consider and discuss the legal, ethical or practical problems that exist for each action option and conclude with a persuasive argument supporting your decision.
Answer:
The government should not go ahead with this plan.
Explanation:
If the government decides to proceed with its plan to pass a law that authorizes the management of a hospital to force people who refuse to wash their hands out of a hospital and deny them medical care against their will, then the government will be infringing on people's right to life. While it is necessary to prevent the spread of Clostridium Difficile (C. difficile) , any law that is made to that effect must not abuse the right of access to medical care which is a fundamental right of citizens. This action will be ethically incorrect because it amounts to a government using a high handed approach in discharging its duties.
However, the intention of such a law is to protect the citizenry from the bacteria Clostridium Difficile (C. difficile) . If such a law is not passed, more people may become infected by the bacteria owing to the carelessness of other people. This situation is made worse because the organism is resistant to antibiotics.
However, since prevention of the spread of Clostridium Difficile (C. difficile) is Paramount, I opine that the government should continue to enlighten citizens and appeal to them on the need to practice regular hand washing in order to protect themselves and other people. Passing the said law is a draconian approach to the problem hence it is not in line with the ethics of modern civilization.
It is more civil to continue to appeal to citizens and sensitize them on the importance of regular hand washing as it affects the spread of Clostridium Difficile (C. difficile) .

Alexis is using models of the cell membrane to compare the types of cellular transport. One
model shows a molecule entering through a protein pump. Which ope of cell transport is
being modeled?
A
diffusion because protein pumps are needed to move substances from a higher
concentration to a lower concentration
8
endocytosis, because protein pumps transport substances that are too large to
pass through the cell membrane
active transport, because protein pumps are needed to move substances against a
concentration difference
D
osmosis, because protein pumps allow water to cross the cell membrane
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.

Most enzymes are proteins. Many cells make and use an enzyme called catalase to facilitate the decomposition of hydrogen peroxide (H2O2). The products of the decomposition are hydrogen (H2) and oxygen (O2). Stephanie is investigating the structure and function of catalase, and she is comparing catalase to other proteins. What can Stephanie predict will distinguish the structure of catalase from the structures of the other proteins she is studying? A. many regions made entirely of hydrogen and oxygen B. the chemical properties of the peptide bonds C. the types of amino acids it contains D. the sequence of amino acids it contains
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.
what does the process of breaking and reforming bonds allow cells to make?
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:
1. ATP
Explanation:
Cellular respiration may be defined as the chemical process of breakdown of food in the cell with the liberation of energy in the form of ATP.
Photosynthesis is a chemical process through which green plants most photosynthetic algae synthesize their own food in the form of glucose. While nitrate absorption is the process through which nitrogen in the soil is significantly absorbed by the root of plants in form of nitrates.
Fermentation is initiated with the process of glycolysis, but it does not involve the upcoming two stages of aerobic cellular respiration such as the Krebs cycle and oxidative phosphorylation.

If a father has type A blood and the mother has Type AB blood, they would NOT have a child with which of the following blood types?
AB
A
B
O
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.
Type A contains antigen A and its genotype can be A|A or A|O. Type B contains the B antigen, whose genotype can be B|B or B|O. Blood type AB contains both antigens and a single genotypic expression A|B Type O blood lacks surface antigens, with genotype O|O.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.
Which career combines DNA technology and forensics? pharmaceuticals paternity testing environmental studies genetics
Answer:
B. Paternity
Explanation:
Edge 2020
The career that combines DNA technology and forensics is paternity testing. The correct option is B.
What is paternity testing?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.
