An unstable nucleus with too many protons emits energy and an alpha particle during alpha decay. An alpha particle is actually a helium nucleus because it has two protons and two neutrons. A nuclear equation can be used to represent alpha decay. Thus, option C is correct.
What is the alpha decay releases of radiation from helium?When an unstable nucleus changes to another element, a nuclear process called “alpha decay” produces a particle consisting of two protons and two neutrons. The helium nucleus that is being ejected is known as an alpha particle.
An alpha particle is released when a nucleus becomes unstable due to having an excessive number of protons. An alpha particle is a helium nucleus, since it has two protons and two neutrons. This is the alpha decay.
Therefore, Each of the two protons and two neutrons that make up an alpha particle is a helium nucleus that has lost its planetary electrons.

Which type of weathering is the result of water freezing and expanding inside the cracks of rocks when it freezes?
a.biological weathering
b.chemical weathering
c. frost wedging
d. deposition
Answer:
C. frost wedging
Explanation:
Frost wedging is the process by which water seeps into cracks in a rock, expands on freezing, and thus enlarges the cracks. So, therefore, the answer must be C.
called CF is a condition that causes excess mucus production in the lungs and if untreated causes early death. CF is caused by a deletion of 3 letters in the gene sequence. How might this deletion cause excessive mucus production?
Answer:
The correct answer is - by absorbing too much sodium and water into the cells in the respiratory system.
Explanation:
Cystic fibrosis or CF is a genetic disorder that is caused by the presence of two defective genes that leads to the production of thick and sticky mucus in an individual that affects the respiratory and digestive system by clogging mucus in it.
Due to defective genes, there is an abnormal electrolyte transport system develops in which cells of the respiratory system including the lungs absorb an excessive amount of salt (sodium) and water. It all caused by deletion of the three letters which means an amino acid from a gene that leads to the disruption of the protein that controls the production of the mucus and abnormal electrolyte transport.
Color-blindness is a X-linked recessive disorder. under what circumstances will manifest in a child?
A) if the child is a male and it's mother has the recessive allele
B) if the child is a female and it's father has the recessive allele
C) If the child is a female and it's mother has the recessive allele
D) If the child is male and it's father has the recessive allele
Answer: A
Explanation: the gene can only be passed on the x gene, so if you are a male, you only have one x gene, so it dominates without the presence of another x gene
Answer:
A
Explanation:
because males are XY and females are XX, if two people have a son, he will receive a Y chromosome from his father and an X chromosome from his mother, if one of her alleles is recessive color blindness, there is a chance he could be color blind.

What are capillaries?
Select one:
a.
blood cells that fight infection
b.
vessels through which nutrient and gas exchange take place
c.
chambers of the heart that pump blood throughout the body
d.
the liquid part of the blood that transports hormones
b. Capillaries are vessels through which nutrient and gas exchange take place.
Capillaries are the smallest blood vessels in the body and are responsible for facilitating the exchange of nutrients, gases, and waste products between the bloodstream and surrounding tissues. They connect the arterioles (small branches of arteries) and venules (small branches of veins).
Capillaries have thin and permeable walls, consisting of a single layer of endothelial cells. This structure allows for the exchange of substances between the blood and surrounding tissues. Oxygen and nutrients diffuse out of the capillaries into the tissues, while carbon dioxide and waste products from cellular metabolism diffuse into the capillaries to be carried away.
The extensive network of capillaries ensures that every cell in the body is located in close proximity to a capillary, allowing for efficient exchange of substances. This exchange includes the delivery of oxygen and nutrients to the cells, as well as the removal of carbon dioxide and waste products.
While blood cells, such as red blood cells and white blood cells, are present in the capillaries, they are not the defining characteristic of capillaries. Instead, capillaries are primarily associated with facilitating the exchange of substances between the bloodstream and the surrounding tissues.
Therefore, option b is the correct answer as it accurately describes the role of capillaries in facilitating nutrient and gas exchange.

Explain in your own words why a dominant trait is not always a common trait.
Answer:
Describing a trait as dominant does not mean it is the most common; it means that it is expressed over the recessive trait. For example, tongue rolling is a dominant trait, controlled by the dominant version of a particular gene (R). Individuals with one or two copies of R will exhibit tongue rolling.

In a certain species of mammals, gray fur (G) is dominant to white fur (8) and brown eyes (B) are
dominant to blue eyes (b). An animal with white fur and blue eyes is crossed with an animal that has
gray fur and brown eyes (GGBb). What trait will appear in all of the offspring of this mating?
Gray fur (G) trait will appear in all of the offspring of this mating.
This is because one parent has GG. Even if the other parent has gg, all the offspring will have Gg and G is dominant.
Dominant and Recessive traits:Dominant and recessive traits exist when a trait has two different forms at the gene level.
The trait that first appears or is visibly expressed in the organism is called the dominant trait. The trait that is present at the gene level but is masked and does not show itself in the organism is called the recessive trait.Learn more:

what type of selection causes a shift in advantageous traits
Answer:
Natural Selection

Organisms are divided into different kingdoms based on differences in their characteristics. Two major characteristics that scientists
use to determine which kingdom an organism belongs to are
ability to make food and ability to swim.
OA
OB ability to swim and number of cells.
OC.
ability to fly and size of organism.
OD
ability to make food and number of cells.
Answer:
A. ability to make food and ability to swim
Explanation:
Living organisms have been grouped into an hierarchical system of classification that begins with the kingdom, which is the most inclusive taxon. Organisms were placed into kingdoms based on two major criteria namely; their nutrition and mobility.
Their nutrition depends on their ability to make food by themselves (autotrophic) or not (heterotrophic) while their mobility depends on their possession of structures for locomotion.
