The polio virus uses the D. mucous membranes only as its primary portal of entry

Poliovirus is primarily transmitted through ingestion of water contaminated with feces containing the virus. The portal of entry for the polio virus is through the mucous membranes. The mucous membranes include the lining of the mouth, nose, and gastrointestinal tract. Ingesting contaminated water or food allows the virus to enter through the mucous membranes of the gastrointestinal tract.

The virus can enter through cuts, abrasions, or insect bites. The virus can also enter through the respiratory tract when someone inhales contaminated droplets or aerosols. Once the virus enters the body, it targets the motor neurons in the spinal cord and brain stem. It then replicates, causing inflammation and damage to these areas. This can result in paralysis or death in severe cases.

Preventing polio transmission involves improving sanitation and hygiene practices, such as washing hands regularly and properly disposing of feces. Vaccination is also essential in preventing the spread of the virus. The polio vaccine is safe, and effective, and has been used successfully for many years. In summary, poliovirus can enter the body through mucous membranes (Option D).

When a mouse with two copies of the Clock mutation is placed in a lab where the lights come on each day at 7:00 AM and go off each day at 7:00 PM, the activity rhythm of this mouse will display in 24 hours.

Zip, a brand-new hamster mutant, has an 8-hour daily rhythm when there are no light cues. An adult hamster with the tau mutation (with its own SCN lesioned) would have an 8-hour period for its rhythm if the embryonic SCN from a healthy animal were transplanted into its brain.

In animals, the suprachiasmatic nucleus (SCN) serves as the main circadian pacemaker. In scattered cultures, individual SCN neurons can produce their own circadian rhythms of clock gene expression and neuronal firing. However, enough membrane depolarization, intracellular calcium, and cAMP concentrations are required for SCN rhythmicity.

The zona pellucida is the region between the developing oocyte and the granulosa cells.

A mammalian ovum's zona pellucida, which is made of glycoproteins, is the translucent, more or less elastic, noncellular outer layer or envelope. Glycoproteins are in charge of sperm's species-specific attachment to unfertilized eggs, the induction of acrosomal exocytosis in sperm, and the inhibition of sperm attachment to fertilized eggs.

The glycoprotein layer known as the zona pellucida covers the mammalian oocytes. The corona radiata and the oocyte plasma membrane are separated by a zone called the zona pellucida. The zona pellucida is crucial for effective fertilization because it triggers the acrosome reaction, which allows sperm to enter the secondary oocyte.

The effects of capillary distention resulting from high vessel compliance on resistance and blood flow  can depend on several factors such as the

Capillary distention resulting from high vessel compliance can affect resistance and blood flow in several ways:

Increased Compliance: High vessel compliance leads to an increase in the total cross-sectional area of capillaries, which results in a decrease in resistance to blood flow. This decreased resistance can increase blood flow through the capillaries.

Increased Distension: High vessel compliance also leads to increased distension of the capillaries, which can increase the permeability of the capillary walls. This increased permeability can lead to an increased exchange of fluids and nutrients between the blood and surrounding tissues.

Decreased Perfusion Pressure: Capillary distension can also result in a decrease in perfusion pressure, which is the pressure gradient that drives blood flow through the capillaries. This decrease in perfusion pressure can decrease blood flow through the capillaries.

Overall, the effects of capillary distention resulting from high vessel compliance on resistance and blood flow are complex and can depend on several factors such as the degree of distension, the location of the capillaries, and the overall health of the cardiovascular system.

Explanation:

The outgroup is the most distant taxonomic group that shares no traits or characters with the lineages of interest, which compose the ingroup. You can compare the outgroup with the ingroup to determine the evolutive relationship and which characters are primitive or derived.    

Even though the outgroup shares a common ancestor with the ingroup, this is placed far away in evolution, making the outgroup to be the taxonomic group less related to the other lineages. The lineages in the ingroup share another common ancestor that is more recent in history.

To select the outgroup, you need to focus on what you are interested in. There might be several outgroups, but you should choose the one that is more related or closer to the ingroups. This selection is important because you need to make comparisons to understand the evolution of specific traits.  

In the exposed example, we need to focus on animals that have four limbs. Then, we might assume that the ingroup is composed of Amphibians Crocodiles Dinosaurs. Sharks and Ray-Finned Fish do not have four limbs, so they might be considered outgroups.

From these two outgroups, sharks have a cartilaginous skeleton, while Ray-Finned Fishes have a bony skeleton. This fact makes ray-finned fishes more related to the ingroup than the sharks. So,

A process by which one of the extreme variations of a trait is favored.

A population tends to evolve toward one end of a trait range due to a natural process called directional selection. Some characteristics, like eye color, are discrete and have distinct variations, but other characteristics are continuous and have a large range of almost infinite values (think height). Only one variety will be chosen for a specific attribute under directed selection (only blue eyes).

The highest or lowest value of a continuous feature will be chosen if a directional selection is applied (only tall people). When a population is subjected to directional selection over time, the qualities that are selected for will remain stable while the traits that are selected against will disappear.

He will use a radioactive element with a long half life of greater than 1 billion years

Explanation:

Rocks are an aggregation of solid mass which is usually rich in minerals. The age of rocks is established using radiometric dating method.

According to Oxford Dictionary, radiometric dating is "a method of dating geological specimens by determining the relative proportions of particular radioactive isotopes present in a sample."

The age of rocks can only be ascertained using isotopes that have very long half lives because many of these rocks are very old (aged billions of years) hence their age can only be determined using elements that has a half life greater than 1 billion years.

The range of the function g(x) = |x – 12| – 2 is {y | y > –2}.


To find the range of a function, we need to determine all possible output values (y) that the function can produce for different input values (x). In this case, g(x) is defined as the absolute value of the difference between x and 12, minus 2.
Since the absolute value of any real number is always non-negative, |x – 12| can never be less than 0. Therefore, the minimum value of g(x) occurs when |x – 12| = 0, which happens when x = 12. At x = 12, g(x) = -2, which is the lower bound of the range.

On the other hand, as x moves away from 12 in either direction, |x – 12| increases, causing g(x) to increase as well. As a result, the range of g(x) consists of all values greater than -2, but there is no upper bound. Therefore, the range of the function g(x) is {y | y > –2}.
