El agua destilada y el agua de chorro son hipotónicas comparadas con la sangre. Si el glóbulo rojo se sumerge en una solución que tiene una osmolaridad menor a 0.32, el agua entra al glóbulo rojo, haciendo que éste se hinche (turgencia) y rompa si el agua que entra es considerable (proceso de hemólisis).                                                                                              ESPERO QUE TE AYUDE :)

Answer 2

When a blood sample is placed in distilled water for two hours. The blood cells gained water because they were placed in a hypotonic solution. Thus, the correct option for this question is B.

What is a Hypotonic solution?

A Hypotonic solution may be defined as a type of solution that possesses a lower osmotic pressure than the solution through which it is compared.  This type of solution generally has a lower solute concentration.

Distilled water significantly behaves hypotonic to the red blood cells. Due to this, the red blood cells swell, and red-colored pigment known as hemoglobin leaks from it as a cell increases its size. Due to this, the color of the solution changes into transparent red-pink.

Therefore, when a blood sample is placed in distilled water for two hours. The blood cells gained water because they were placed in a hypotonic solution. Thus, the correct option for this question is B.

Answers

Karyotype have 23 pairs of chromosomes

What is Karyotype ?

Each eukaryotic species' nuclear genome is split up across several chromosomes that are specific to that species. A haploid human nucleus (i.e., sperm or egg) normally has 23 chromosomes (n=23), whereas a diploid human nucleus has 23 pairs of chromosomes. The term "karyotype" refers to an individual's total number of chromosomes. Each of the 46 structures is a replicated chromosome, despite the fact that it is challenging to see the two sister chromatids for each chromosome at this resolution because the cell was in metaphase.

There are 46 chromosomes, as expected. The chromosomes' lengths vary, as you can see. In fact, this characteristic inspired the names of human chromosomes. One is our longest chromosome; two is the next longest; and so on. The chromosomes are often grouped into the pattern depicted , and the resulting picture is known as a karyogamy. A geneticist can ascertain a person's karyotype via a karyogamy, which is a written depiction of their chromosomes that includes any abnormalities.

What type of macromolecule is used in cell membranes for facilitated
diffusion

Answers

Answer:

Lipoprotein molecule

Carrier proteins are used in cell membranes for facilitated diffusion.

The movement of molecules in the direction specified by their relative concentrations inside and outside of the cell occurs during facilitated diffusion, just as passive diffusion.

The direction in which molecules move across the membrane is dictated by their concentration gradients and, in the case of charged molecules, by the electric potential across the membrane because there is no external source of energy.

The facilitated diffusion of carbohydrates, amino acids, and nucleosides through the plasma membranes of most cells is caused by carrier proteins. One of the most crucial transport tasks of the plasma membrane is the uptake of glucose, which acts as a key source of metabolic energy. The glucose transporter is a well-studied example of a carrier protein.

Drugs use different mechanisms to incorporate and fixate into the hair, and these are useful to determine if a person is currently consuming drugs or not, and for how long. Option B) Drug use is currently happening.

How are drugs incorporated into the hair?

Several studies have been done to explain drug incorporation mechanisms in hair. Among different mechanisms, the most significant ones are,

Active or passive diffusion from blood to the dermal papilla from which hair grows.Through sweat and other secretions.From the environment that might deposit drugs on hair.

Usually, before making a drug analysis, hair must be washed to avoid considering external environmental drugs deposited on hair (the last option).

Once drugs incorporate into the hair, they bond to different components composing highly stable complexes that can not be altered for several years. In fact, drugs can remain in the hair for hundreds of years.

According to this information, if after the analysis drugs were only found in the hair root, it might suggest that drugs are recently and currently being consumed.

Why do fungi not produce egg or sperm cells?

There are no other organisms that can help fungi pollinate.
Fungi do not produce flowers or cones to make egg or sperm cells.
Fungi reproduce using spores as their reproductive cells.
Fungi are not large enough to create egg or sperm cells.

Answers

Fungi do not produce egg or sperm cells because they reproduce using spores as their reproductive cells.

Fungi undergo a reproductive phase by producing and releasing enormous amounts of spores after a period of intense growth. Spores are often solitary cells that are created by mycelium fragmenting or within specialized structures (sporangia, gametangia, sporophores, etc.).

Spores can be created directly through asexual reproduction or indirectly through sexual reproduction. As with all living things, sexual reproduction in fungi entails the joining of two gametes (sex cells), which brings two nuclei together. Asexual reproduction, which is easier and more direct, can be carried out in a number of ways.

If all planets were the same distance from the sun, which would have the largest gravitational force between itself and the sun? Why?

If all planets were the same mass, which would have the lowest gravitational force between itself and the sun? Why?

Answers

Answer: Mercury

Explanation:

Looking at the general equation for gravity attached below we see that radius is indirectly proportional so as it increases the force decreases.

The masses of m1 and m2 are directly proportional so as either of them increases then the gravitational force increases.

In this example the radius and m2 are all the same so the only difference will be the mass of the other planets.

Mercury has the lowest mass of all the planets in the solar system so it will also have the lowest gravitational force between it and the sun in this example.

Diabetes can cause high blood glucose levels, which can harm your blood vessels as well as the nerves that regulate your heart and blood vessels. Heart disease may eventually result from this injury.

Those who have diabetes typically have heart disease at a younger age than those who do not. When compared to those without diabetes, adults with diabetes have approximately twice the risk of developing heart disease or stroke.

The good news is that actions you take to control your diabetes can also help reduce your risk of developing heart disease or stroke.

Why is the blood sugar level of a diabetic individual so high?

However, after the majority of the cells that generate insulin are destroyed, the pancreas is unable to produce enough of it, which prevents the glucose from entering the cells and causes an excess of glucose to be produced of dissolved blood sugar floating through the circulation. Risky complications may result from this. The name of this ailment is diabetic ketoacidosis.

Question: what 3 organisms one could be found in Alabama’s biome?

Solution (explanation):

Let us remember that a biome is understood as each ecological unit into which the biosphere is divided according to a set of climatic and geological factors that determine the type of vegetation and fauna.

Alabama is one of the most biologically diverse states in the United States of America and is a global hotspot of diversity for several groups of plants and animals. In fact, this diversity is a product of Alabama's climate, geologic diversity, and rich evolutionary past. Alabama has more than 6,350 species.

One of the organisms in Alabama is the Salamanders which are one of several groups of southeastern organisms that are famous for their degree of speciation. In fact, the ecosystem of Alabama houses Red Hills Salamander.

On the other hand, the most dramatic evolutionary influence of the Southern Appalachian Mountains has been on Alabama's freshwater fauna. In fact, in Alabama, we can find fish, snails, mussels, and crabs because they are all easily isolated in the shallow streams in the headwaters of major rivers. Consequently, more freshwater species are found in the Southeast than anywhere else outside the humid tropics. Alabama is at the center of this aquatic biodiversity hotspot. In fact, speciation was especially rampant in the Tennessee River and Mobile River Basin. Therefore, another organism that we could find in the ecosystem of Alabama is the fish Vermilion Darter.

Finally, the region has more than 100 plant genera, for example, an example of another organism found in the Alabama ecosystem is the American beech.

Answer: we can conclude that the correct answer is: we can conclude that 3 organisms that one could be found in Alabama’s biome?

1. Red Hills Salamander.

2. Vermilion Darter.

3. American beech.
