Answer:
Compare and Contrast the relationships between the speed of electromagnetic and mechanical waves as they travel through different mediums is explained below in details.
Explanation:
As per the mechanism, the waves can be distinguished as electromagnetic and mechanical waves. Electromagnetic waves are those fluctuations that have no mechanism to progress whereas mechanical waves demand a mechanism for their communication. Electromagnetic waves progress in a vacuum whereas mechanical waves don't have.

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.
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.
QUESTION 9
if a woman who is a carrier for Fragilex syndrome (an X-linked disorder) has children with a man who does not have the disorder, what chance do their
daughters have of being carriers of Fraglese
None
50%
25%
100%
Answer:
Daughters who are descendants of a woman carrier of Fragile X Syndrome and a healthy man will have a 50% chance of having or being carriers of the syndrome.
Explanation:
Fragile X syndrome has an autosomal dominant inheritance pattern, linked to the X chromosome. That is, someone with an altered X chromosome can either be a carrier or have the syndrome.
In this case, the mother is a carrier of the altered chromosome (X) while the father is neither a carrier nor has the condition (XY).
Cross X x XY
Alleles X Y
[tex]X^{f}[/tex] [tex]X^{f}[/tex]X [tex]X^{f}[/tex]Y
X XX XY
The couple has a 50% chance of having daughters, and of those daughters half (50%) have the chance of having an Xf chromosome, and being a carrier or suffering from the syndrome.

Explanation:
A wheat plant that is light green in color is found growing in a field. Biochemical analysis reveals that chloroplasts in this plant produce only 50% of the chlorophyll normally found in wheat chloroplasts. Propose a set of crosses to determine whether the light-green phenotype is caused by a mutation in a nuclear gene or in a chloroplast gene.
Answer:
Set of crosses:
Wild-type male x light-green female
Light-green male x wild-type female
Explanation:
Chloroplast genes are inherited maternally and, therefore it would be expected to observe this mode of inheritance:
- Wild-type male x light-green female >> offspring 100% light green
- Light-green male x wild-type female >> offspring 100 % wild-type
Moreover, nuclear genes are inherited from both parents, and, therefore, in the case of complete dominance, it would be expected to observe the following results:
1- When wild type is dominant:
- Wild-type male x light-green female >> offspring 100% wild type
- Light-green male x wild-type female >> offspring 100% wild-type
2- When light-green is dominant:
- Wild-type male x light-green female >> offspring 100% light-green
- Light-green male x wild-type female >> offspring 100% light green
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.

Explanation:
got it right , edge 2020
The picture shown here is of sedimentary rock. It is visible so because of the identification features of a rock as shown in the image.
What is the formation of rock making process ?The process is that the soil and the sand that gets accumulated and together with the mud gets collected in order to form a hard mass by the passing of time called as rock.
The kind of rock identification is done on the basis of rock identification aspects that are decided for each type of rock that has been kept under observation. In sedimentary rock, the grains and the displacement of rock grains together gives a larger or smaller appearances.
The types of layers and mud particles joined together along with the ripple marks that have been put together shows the marks on the rocks.

Describe what happens in each phase of mitosis.
Answer:
Mitosis is divided into four stages.
Early, late, middle, and late.
Prophase – At this stage, the genetic material in the nucleus condenses, revealing duplicated chromosomes. The mitotic spindle begins to form outside the cell nucleus.
At this stage, the centrosomes of the chromosome pairs line up in the center of the cell. The spindle fiber attaches each genetic code centromere to the two poles of the spindle. Late stage – At this stage, genes segregate and migrate along the spindle fibers to the ends of the cell.
Telophase – At this stage, previously separate and condensed chromosomes begin to spread into a jumble of chromatin.

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) .
