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.

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:
Water as a Molecule and Compound
Explanation:
When two atoms form a chemical bond, they make a molecule. Hydrogen and oxygen are both elements, but they also normally exist as molecules consisting of two atoms (H2 and O2). Because hydrogen forms bonds with oxygen to make water, water is a molecule. Water is also a compound.

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.
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.

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.

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.

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.

In your own words, explain how a person may taste the bitterness of PTC by using the
following vocabulary words in your explanation (choose any order): trait, gene, genotype, phenotype, and alleles.
Underline each word as you use it in your explanation. In this explanation, you can treat PTC taste sensitivity as a single-
gene trait.
Answer: PTC gene has two main alleles; one that codes for tasting and the other non-tasting. The allele for tasting determines a trait of tongue papillae that can bind the PTC molecules. Non-tasting allele forms papillae that are unable to bind PTC effectively. Therefore, the combination of these alleles in the genotype of a person determines their phenotype – PTC sensitivity.
Answer:
Individuals are often characterized as “tasters” or “non-tasters” of PTC, but there is some variability amongst tasters in how much bitterness they can detect. ... The ability to taste PTC is due changes in the TAS2R38 gene that affects the function of bitter taste receptors on the tongue therefore, the combination of these alleles in the genotype of a person determines their phenotype – PTC sensitivity.

Imagine that a biological anthropologist 10,000 years in the future is examining our fossil remains. The anthropologist notices that humans have broad incisors and molars with rounded cusps. How do you think the anthropologist would interpret these traits---what diet would these traits indicate
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.
