Answer: The brain
Explanation:
The brain is arguably the most important organ in the human body. It controls and coordinates actions and reactions, allows us to think and feel, and enables us to have memories and feelings—all the things that make us human.
yes, i agree that it is your brain, *including every other organ you can't live without Imao* your brain is responsible for you walking, reacting to heat or whatever reaction. while you can't live without your heart, which is a common answer for this question, your nervous system has to be functioning properly (which is what your brain assists in) for your heart to pump correctly.
Scenario: In a population of spiders living on Arachnid Island, most of the spiders are gray; a few are brown. On nearby Spider Island, there is another population of the same species. There, most of the spiders are brown; a few are gray. The ocean between these islands is full of hungry fish, and the spiders don't swim, so there is very little movement of spiders between the islands.Initial makeup of each population:Arachnid Island: 90% gray, 10% brown Spider Island: 10% gray, 90% brownThen a bridge is built to connect the islands so that tourists can ride their bikes from one to the other. The bridge is also a nice environment for spiders, so they start to move back and forth between the islands.How do you predict the makeup of the populations will be changed if this movement continues for many generations? Answer the questions below to identify and describe this change in the population.1. Is this an example of mutation, selection, genetic drift, or gene flow?
Due to the building of the bridge, now both spiders population are communicated and are able to cross, this will lead to the allele frecuency to vary, which is an example of genetic drift.

The complete chart indicating the number of chromosomes after meiosis, in body cells, in gametes and after mitosis are indicated in the given image.
Meiosis is the process of cell division in which the number of chromosomes are reduced to half. This is the reason why it is also called the reductional division. The process occurs in two phases: Meiosis I and Meiosis II. Meiosis I is the phase where actual reduction takes place.
Mitosis is the process of cell division where the daughter cells are identical to the parent cell. Here, the number of chromosomes remain the same and hence is called equational division.

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?
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.

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.

You are studying an Newley discovered organisms karyotype. So far, you have discovered that is is diploid and has 15 homologous chromosomes. After S phase, how many homologous chromosomes, individual chromosomes, and sister chromatids are present in this new organism?
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 percent of your body mass is made of water?
Answer:
60%
Explanation:
In adult men, about 60% of their bodies are water. However, fat tissue does not have as much water as lean tissue. In adult women, fat makes up more of the body than in men, so they have about 55% of their bodies are made of water. Most of the human body is water, with an average of roughly 60%. The amount of water in the body changes slightly with age, sex, and hydration levels. The amount of water in the human body ranges from 60-80%. The brain and heart are composed of 73% water, and the lungs are about 83% water. The typical percentage of the human body that is water is 60% in adult men according to Dr Jeffrey Utz of Allegheny University and 50% in adult women.

In the core of cells, we can find the nucleus, which controls many of the cell functions and contains our DNA, that is found in chromosomes, thread-like structures made up of packaged DNA. The DNA, in turns, carries genes, sequences of nucleotides responsible for a product, which can be either an RNA molecule or a protein.
People with diabetes have several medical concerns. One concern Is hyperglycemia (high blood sugar concentrations). Hyperglycemla for extended times can cause damage to the cells of blood vessels, leading to risk of heart attock, stroke, kidney disease, and more. Using osmosis, explain why hyperglycemid would be clamaging to blood vessel cells.
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.

Drug use is not identified.
Drug use is currently happening.
Drug use stopped several weeks ago.
Drug use has occurred for several months.
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.
Option B is correct. Drug use is currently happening.

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

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.
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.
