Answer:

The primary role of RNA is to convert the information stored in DNA into proteins.

Explanation:

Specifically, messenger RNA (mRNA) carries the protein blueprint from a cell's DNA to its ribosomes, which are the "machines" that drive protein synthesis.

The statement that is not true concerning the cranial nerve is that it controls the muscle of the back and neck

The cranial nerve is part of the peripheral nervous system.

Sensory impulses enter the brain and motor impulses leave it directly through the cranial nerves.

In humans, there are 12 pairs of cranial nerves that arise from the ventral surface of the brain.

The vestibular nerve forms the eight cranial nerve and is responsible for detecting balance.

The cochlear is part of the cranial nerve, which is also called auditory nerve, that is responsible for hearing.

The nerve that controls the muscles of the spine and back is the spinal nerve, making the statement a false statement.

Answer: Poultry are domesticated birds used for meat, eggs and feathers. Chickens fall into the poultry category. So, no they are not the exact same thing, chickens are just a part of poultry.

Answer:

To test this hypothesis, geologists around the globe measured iridium concentrations at sites known to be 66 million years old. Because geologists knew that asteroid impacts cause minerals to fracture, they also measured the clay layers for shock-fractured minerals, like quartz.

Explanation:

These geologists raised this hypothesis because of the large crater that was in this place and the amount of fossils that are in the K / Pg boundary layer. Also the high levels of iridium.

In 1979 the scientists Luis Alvarez and Walter Alvarez led the discovery of a carbonate clay layer with iridium concentrations ten times higher than those expected in the Yucatan Peninsula.

This allowed them to propose a hypothesis about the mass extinction of dinosaurs caused by the collision of an asteroid in the Earth's crust because iridium is a rare element in the Earth's crust and ten times more concentration of it was found in this area.

On the other hand, this hypothesis was reinforced when in other parts of the world it was found that the boundary layer k / Pg had high concentrations of iridium.

The flow of sodium and potassium ions across the typical nerve cell membrane happens during action potentials, or spikes.

Define action potential.

Action potentials, those electrical impulses that travel throughout your body, are nothing more than a brief change in the membrane potential of the neuron brought on by ions that are suddenly flowing into and out of the cell.

The three phases of an action potential are depolarization, overshoot, and repolarization.

The process of bringing the membrane potential first up to the threshold potential is known as hypopolarization. A substantial inflow of sodium ions results from the threshold potential opening voltage-gated sodium channels. Depolarization is the name given to this stage. Depolarization causes the inside of the cell to become increasingly electropositive as the voltage approaches the electrochemical equilibrium for sodium, which is +61 mV. The overshoot phase is this period of very high optimism.

Following the overshoot, the sodium permeability abruptly drops as its channels close. The overshoot value of the cell potential activates voltage-gated potassium channels, leading to a significant potassium efflux and a reduction in the electropositivity of the cell. Repolarization is the current phase, which works to return the resting membrane potential. Every time repolarization occurs, hyperpolarization—a condition in which the membrane potential is more negative than the baseline membrane potential—occurs first. But shortly after, the membrane sets the values of membrane potential once more.

In the case of a phenotypically normal woman marrying a man who is heterozygous for CMT disease, an autosomal dominant disorder, the chances that their son would inherit the disease are 50%.

The woman in this case is phenotypically normal, which implies she does not have CMT illness. The man has CMT disease and is heterozygous for it, which means he has one normal copy and one mutant copy of the gene.

The boy acquired one copy of the mutant gene from his father, giving him a 50% chance of acquiring the condition.

Thus, their son has a 50% risk of inheriting the condition.

There will be 50% blue eyes (genotype bb) and 50% brown eyes in the offspring (genotype Bb). There will be 50% homozygous dominant offspring and 50% heterozygous offspring (genotype Bb) (genotype BB).

Blue eye color is subordinate to brown eye color. Consequently, it is possible that both parents of a child with blue eyes and brown eyes have the heterozygous genotype Bb. Consequently, it is evident from the square below that there is a 25% chance of having a blue-eyed (bb) child.

The Punnett square below shows that there is a 25% chance of having a healthy homozygous (AA) child, a 50% chance of having a healthy heterozygous (Aa) carrier child, and a 25% chance of having an abnormal homozygous (AA) child at each birth.

Answer:

Coxsackievirus A16

Since the gibbon has 44 chromosomes and the siamang has 50 chromosomes, their hybrid offspring would have 47 chromosomes (22 from the gibbon and 25 from the siamang).

It is unlikely that the hybrid offspring would be able to form viable gametes because the uneven chromosome number would make it difficult for chromosomes to pair up properly during meiosis.

When the hybrid offspring attempts to produce gametes, the unequal number of chromosomes may result in aneuploid gametes, which have too few or too many chromosomes.

These gametes are typically not viable and may result in infertility or developmental abnormalities if fertilization occurs. Therefore, it is unlikely that the hybrid offspring would be able to produce viable gametes.

Within our solar system early on, Earth was nearly undefinable compared to now. Our earth used to be made out of magma, and it was extremely hot. The time was not right for life to form. The atmosphere was formed by this magma we talked about spewing from mini-volcanoes that consisted around our early version of the Earth. Then, over time, the Earth evolved, and became what we know today as our home planet.

Answer:

Meiosis

Explanation:

The process that could occur in maple trees to decrease the chromosome number in pollen cells from 52 to 26 is called meiosis.

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in the formation of haploid cells with half the number of chromosomes of the original cell. In meiosis I, the chromosomes are replicated and then lined up in homologous pairs, and then are separated into different nuclei during meiosis II, resulting in four haploid cells, each with half the number of chromosomes as the original cell.

So in the case of maple trees the process of meiosis would reduce the number of chromosomes from 52 to 26 in the pollen cells.

Answer: 1. superior 2. pubic symphysis 3. urinary bladder

Explanation:

Given our understanding of the human anatomy, we can confirm that by 12 weeks, the uterus is just superior to the level of the pubic symphysis and is about the size and shape of a large grapefruit. As the uterus expands, it impinges on the space occupied by the bladder.

As the question tells us once the spaces are filled in, the uterus, which holds the fetus during development, expands as the fetus grows in size. This expansion causes it to extend to the spaces superior to the pubic symphysis and the space occupied by the bladder.

The expansion of the uterus into the space occupied by the bladder causes this organ to have very limited space to expand, thus greatly limiting the amount of urine it can hold which causes more frequent trips to the bathroom.
