Answer:
the fundamental unit of heredity
Explanation:
DNA is a double stranded helix structure. Each strand is made up of a string of nucleotides.
A gene is a region of DNA, usually tens of thousands of nucleotides long. At the simplest level, one gene encodes for one trait. Therefore, the gene can be described as the fundamental unit of heredity.
Genes work by coding for specific proteins, which carry out essentially all the functions in the cell.
Which of the following is a true statement about replacement-level fertility?
A) It equals the average number of children a woman will give birth to during her child-bearing years.
B
It equals the annual number of live births per 1,000 people in a population.
с
It equals the natural increase of a population in one year.
D
It is found by subtracting the number of emigrants from the number of immigrants in one year.
E
It is greater in countries with high infant-mortality rates than in countries with low infant-mortality rates.
Answer: It is greater in countries with high infant-mortality rates than in countries with low infant-mortality rates.
Explanation:
Replacement level fertility is referred to as the total fertility rate at which a population is being replaced from one generation to another generation. It should be noted here that fertility rate here refers to the average number of children born that a woman has.
The Replacement level fertility rate in most countries is around 2.1 children per woman. The replacement level fertility is greater in countries with high infant-mortality rates than in countries with low infant-mortality rates.
The correct option is E.
If a woman has both alleles in her body cells, what will her eggs contain?
If a woman has both alleles in her body cells, then her eggs will contain only one of the alleles. This is because during the formation of eggs, a process called meiosis occurs, which randomly separates and distributes the alleles to the daughter cells. Therefore, each egg will contain one of the two alleles that the woman carries.
What is allele ?An allele is a variant form of a gene that is responsible for the expression of a particular trait or characteristic of an organism.
If a woman has both alleles in her body cells, it means that she is heterozygous for that particular gene. This means that she has two different versions (alleles) of the gene, one inherited from each parent.
During the process of meiosis, which produces eggs, the two alleles will segregate, meaning that each egg will receive only one allele.
The allele that ends up in each egg is random and depends on the particular orientation of chromosomes during meiosis.
So, the woman's eggs will each contain one of the two alleles she carries, and there is a 50% chance that each egg will contain either allele.

A food handler reports to work with obvious yellowing of the eyes and skin. What should the person be checked for?
Answer:
Hepatitis A
Explanation:
Hepatitis A refers to a liver disease or infection that results in mild to severe illness in humans and it is typically caused by the Hepatitis A Virus (HAV).
Generally, the main cause of Hepatitis A is as a result of the ingestion of food or consumption of water that has been contaminated by the Hepatitis A Virus (HAV) or getting in direct contact with fluids from an infected person.
Some of the symptoms of Hepatitis A are loss of appetite, feverish conditions, itching, nausea, fatigue, diarrhea, dark-colored urine, malaise, abdominal pains, yellowing of white portions of the eyes and skin (jaundice).
Hence, if a food handler reports to work with obvious yellowing of the eyes and skin. The sickness or illness that the food handler should be checked for as an adult is Hepatitis A.
Hepatitis A is a viral infection, which affects the liver. The person with obvious yellowing of eye and skin should be checked for Hepatitis A.
Hepatitis A is a viral infection caused by the Hepatovirus A. The virus affects the liver, which may lead to mild to severe illness in the patient. The disease is caused by the consumption of contaminated food and water, personal contact with the infected person, and using used drugs with other persons.

Explanation:
Which organelle that plays a central role in the transport of new molecules from inside to outside the cell?
Answer:
The Golgi apparatus plays a central role in molecular transport after biosynthesis.
Explanation:
Transcription occurs in the nucleus during protein synthesis, followed by translation inside ribosomes. Then, new molecules join the endoplasmic reticulum to be folded and modified. In the Golgi, they are tagged and separated into lysosomes for export outside the cell.
The Golgi system comprises of several regions known as cisternae; they act as independent microenvironments where products requiring their own unique conditions are converted into new, stable biomolecules.

A woman with type AB blood has children with a man who has type o blood. What are the chances they will have a child with type o blood?
25%
0%
100%
50%
Answer:
The chance of a woman with an AB blood type and a man with an O blood type having a child with O blood is 0%.
Explanation:
A mother with blood type AB (AB) will pass either antigen A or antigen B to the offspring, while the father with blood type O (OO) will not pass any antigen.
The result of an AB X OO cross would be
Alleles O O
A AO AO
B BO BO
For this reason, the offspring of this couple will be
Blood type A (AO) 50%. Blood type B (BO) 50%. Blood type O (OO) none.Heredity of blood type depends on the presence of surface antigens on the erythrocyte membrane. Blood type O occurs in persons whose red blood cells do not possess surface antigens A or B.
Surface antigens are what determine blood type, so :
The presence of antigen A determines blood type A. Blood type B depends on the presence of antigen B. Blood type AB has both antigens.Blood type O has no antigens, and for blood type O to manifest, it must have both alleles for O.
A mother AB and father O cannot have offspring with blood type O.

Binding of ________________ to receptors (ligand-gated) on the sarcolemma at the neuromuscular junction is vital for depolarization of the muscle fiber.
Answer:
Binding of ACh (acetylcholine) to receptors (ligand-gated) on the sarcolemma at the neuromuscular junction is vital for depolarization of the muscle fiber.
Explanation:
It allows acetylcholine to be released into this synapse when an action potential hits a neuromuscular junction. Acetylcholine attaches to the nicotinic receptors localized on the post-synaptic membrane of the muscle fibre's motor end plate, a specialized region.
Hence , the answer is ACh (acetylcholine) .

Answer:
They were frugivores
Explanation:
Frugivores are animals that mainly eat raw fruits, vegetables, roots, seeds, shoots, etc. Frugivores need to eat diverse fruits and succulent fruit-like vegetables to fulfill their nutritional requirements, although they can supplement this diet with flowers, nectar, small insects, etc. Among their adaptations for fruit consumption, frugivore teeth are clearly distinct, having broad incisors to peel tough fruit rinds. Moreover, these animals generally have long small intestines to digest the fruit.
I WILL GIVE BRAINLIEST Pretend you're riding the bus to school on a very cold and snowy day. List 3 different phases changes you might see along the way.
While riding the bus to school on a very cold and snowy day three different phases changes you might see along the way are mentioned below:
1. precipitation(the snow falling)
2. evaporation(water turning into vapor)
3. melting(snow turning the water)
What is precipitation, evaporation, and melting?Evaporation is the process in which liquid changes in vapour or gas and it can be easily observed during hot summer days when there is raining and when wet clothes dry in the presence of sunlight. Evaporation is directly proportional to temperature and when rate of evaporation increases the temperature also increases.
Precipitation is the water that is falling from the sky and it occurs when a portion of atmosphere becomes saturated with water vapour.
Melting is the process in which solid is converted into liquid like ice cube converted into liquid water and this is one of the example of melting.
Therefore, the mentioned below are three phases changes :
1. precipitation(the snow falling)
2. evaporation(water turning into vapor)
3. melting(snow turning the water)
