Answer:

0.0085420560747664 Seconds

Explanation:

0.914 ÷ 107 = 0.0085420560747664

The time that the nerve will take for a nerve impulse to travel the full distance of this nerve is 0.00854 seconds.

Sciatica is caused by a pinched sciatic nerve. The most common cause is a herniated disc in the spine or an overgrowth of bone, known as bone spurs, on the spinal bones.

A tumor can occasionally impose pressure on a nerve. A condition, such as diabetes, can also harm the nerve. The speed of something is how fast the object is moving. It is calculated by the distance divivded by time.

Given, the length of the sciatic nerve is 0.914 m

The speed of an action potential is 107 m/s.

The length is divided by the speed

0.914 / 107 = 0.00854 sec.

Therefore, the full distance of this nerve is 0.00854 seconds.

In complete dominance, heter0zyg0us individuals carry both alleles -dominant and recessive- but only express the dominant phentoype. Cross 1: Nn x nn. Cross 2: NN x nn

When the dominant allele completely masks the recessive allele, we talk about complete dominance.

This is the case of individuals that are heter0zyg0us for a particular gene and express the dominant trait. The dominant allele is hiding the expression of the recessive allele.

The Punnett square is a representation that shows the different types of gamete combinations according to the alleles involved in a cross.

Punnett square shows the probabilities of getting offspring with different genotypes and their consequent phenotypes.

So, according to the provided data,

F1) 3 gray fur: 2 black fur

F1) 0 gray fur: 5 black fur

By looking at the phenotype of progeny produced by family 2, and assuming complete dominance, we can infere that black is the dominant phenotype. Why is that? because when you crossed a gray animal with a black animal and the whole progeny is black.

So, assuming a diallelic gene coding for the fur color, we will name

Possible genotypes and phenotypes

Here what you need to analyze is which phentoypes appear among the progeny and their frequencies to get to interprete the parents' genotype.

Now let us analyze the crosses,

F1) 3 gray fur: 2 black fur

You crossed a black animal with a gray animal and the offspring expresses both phenotypes. So the black animal (dominant phenotype) must be heter0zyg0us for coat color.

Parents' phenotype)  gray   and    black

Parentals)                      nn     x     Nn

Alleles in Gametes)   n      n       N      n        

Punnett square)           N          n

                            n       Nn       nn

                            n       Nn       nn

F1) Genotype

1/2 = 50% of the progeny is expected to be heter0zyg0us, Nn

1/2 = 50% of the progeny is expected to be h0m0zyg0us recessive nn

      Phenotype

1/2 = 50% of the progeny is expected to be black -Nn-

1/2 = 50% of the progeny is expected to be gray -nn-

F1) 0 gray fur: 5 black fur

You crossed a black animal with a gray animal and the offspring expresses only the dominant phenotypes. So the black animal must be h0m0zyg0us dominant for coat color.

Parents' phenotype)  gray   and    black

Parentals)                      nn     x     NN

Alleles in Gametes)   n      n       N      N        

Punnett square)           N         N

                            n       Nn        Nn

                            n       Nn        Nn

F1) Genotype

100% of the progeny is expected to be heter0zyg0us, Nn

      Phenotype

100% of the progeny is expected to be black -Nn-

Remember that the Punnett square does not give you information about the number of individuals that can be produced. It just provide information about probabilities of getting individuals with certain genotype of phenotype and their frequencies.

Answer:

Hi. You have not informed the experiment that this question relates to, making it difficult to respond to your query. However, I looked up your query on the internet and found one similar to yours that included an experiment that measured the volume of balloons inflated by people's breath.

The volume of the balloons remains constant throughout the number of tests, according to the results of the experiment. This is due to the fact that when we blow, our lungs prefer to express the same amount of air as when we breathe in regular settings. This is most likely due to the fact that all of the balloons were filled with air when the participants were in the same physical and mental condition, i.e., calm and still, causing the volume of air they breathed and emitted to remain constant. If the individuals in the experiment were exerting some physical effort or were stressed and concerned, the amount of air would be different.

SARS-CoV-2 is a highly relevant example of information transfer that does not conform to the Central Dogma.

Explanation:

A dichotomous key is a classification tool used to identify organisms based on morphological or behavioral characteristics. Individual C is a Roundus tricurlus.

A dichotomous key is a significantly useful tool to classify organisms.

If you have an organism -or part of it- and you need to taxonomically identify it, you use a dichotomous key.

The key provides an easy and fast way for identification by describing different morphological or behavioral traits, leading you to the correct taxonomic classification.

The term dichotomous refers to how information is provided.

You will always have two options per feature (a and b, or 1 and 2), and you will have to choose one of them according to the characteristics of your organism.

Once you choose one of the options according to your organism, the key leads you to the following description, and you will have to choose one of the options again.

You will repeat this until you reach the name of your organism.

The key describes only specific traits that are useful for differentiation.

In the exposed example, for instance, we need to know the name of the individual C.

The first description is about the head size. The key asks you if the individual has a small or a large head. It has a small head, so the key tells you to move to description 2.

1a. Has a small head--------------------------- go to 2

1b. Has a large head--------------------------- go to 3

The second description is about the body shape. The key asks you if your organism has a narrow or a rounded body. And this individual has a rounded body, so the key tells you to move to description 7.

2a. Has a narrow body ------------------------ go to 6

2b. Has a round body -------------------------- go to 7

The seventh description is about antennae. Does your individual have curly or straight antennae? It has curly antennae. You have reached your organism's name. It is a Roundus tricurlus.

7a. Has a curly anteanne ------------------------ Roundus tricurlus

7b. Has a straight antennae--------------------- go to 8

Individual C is a Roundus tricurlus.

1. Complex viruses

2. Enveloped viruses

3. Polyhedral viruses

4. Helical viruses

Viruses are infectious particles comprising of two components:

An outer structural component called the Capsid.

The inner genetic material made of single stranded or double stranded RNA (Ribonucleic Acid) or DNA (Deoxyribonucelic Acid).

The Capsid structure is made up of glycoproteins.

These glycoproteins are encoded by genes present in the viral genome.

The viruses are incapable of reproducing on its own.

They infect the host cells and hijack their metabolic machinery which includes the protein-synthesizing machinery and also utilize the raw materials of the host cells to produce the progeny virions which are then released out the host cells.

The capsid structure is responsible for packaging the viral genome and protecting it from various degrading agents present in the external environment like nucleases.

Answer:

Geologists have hypothesized that the movement of tectonic plates is related to convection currents in the earth's mantle. Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat.

The Earth's plates have a crucial relationship with soil and rocks. This connection is characterized by the plates' movement influencing the formation, distribution, and composition of soil and rocks across the planet.

The asthenosphere, which is semi-fluid beneath them, is separated into many tectonic plates that make up the Earth's lithosphere. Convective currents in the mantle cause these plates to move constantly. Processes like subduction, in which one plate falls beneath another, and rifting, in which plates move apart, are fueled by this movement. Mountains, valleys, and oceanic basins are all the result of these dynamic processes, which have a significant impact on the surface of the Earth.

Through volcanic activity and metamorphism, interactions between the plates also aid in the production of different types of rocks. Therefore, the distribution and makeup of soils and rocks on our globe are significantly shaped by plate movement, which also has an impact on landscapes, ecosystems, and geological characteristics.

Answer:

E. onset of an ice age

Explanation:

The number of daylight hours varies according to a site's latitudinal location and the day of the week or season.

Due to the sphericity of the Earth and its inclination with respect to the Sun, the length of the day or the number of daylight hours depends on the time of year and the latitude of a location.

At latitudes 90°N and 90°S, which are the locations closest to the poles, this fluctuation is particularly pronounced. For instance, the fluctuation of the hours of the day would be as follows in the latitudinal zone of 70°N:

Equinox of spring There is roughly 13.8 hours of daylight each day.

24 hours of light every day on the summer solstice.

12.4 hours of daylight every day during the autumnal equinox.

Zero hours of light each day on the winter solstice.

This variance happens because the Earth revolves around the sun, and the high latitudinal regions occasionally aren't exposed to the sun's rays.
