Answer 1

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.

13. In order to bond a monosaccharide to an existing chain, what molecule must be removed?
14. If a chain of 5 monosaccharides are to be linked together, how many water molecules must be removed?
15. How does the number of glycosidic linkages compare to the number of water molecules produced?

Answers

When two monosaccharides undergo a condensation process with the removal of one molecule of water from the functional groups, a disaccharide—a kind of carbohydrate—is created.

What has to be taken out of some of the monosaccharides before they may be chemically joined?

Dehydration synthesis is a chemical process that converts monosaccharide molecules into poly- or disaccharide molecules. The monosaccharide molecules are united to produce the disaccharide or polysaccharide in such a process, which removes the water-containing components.

A glycosidic bond, a sort of condensation process, is formed when two monosaccharides come together. A water molecule is lost when the carbon of one sugar (often the carbon in position 1) interacts with the hydroxyl moiety of another sugar molecule.

When two monosaccharides are combined and a water molecule is eliminated, disaccharides are created.

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.

Why is *soil erosion* one of the many effects of deforestation?

Answers

Deforestation is the main cause of soil erosion. Without plant cover, there will be an occurence of erosion that will sweep the land into rivers. Trees and their roots gives the soil a defense and refuge from the wind and rain. When forest are eradicated, it makes the land exposed and vulnerable of being washed away by elements. Logging exposes soil to rain splash which lossens soil particles. It erodes the soil making a more impermeable bare surface that increase runoff.

inclination of the ramp vs speed of the toy car

Answers

According to the graph, the inclination of the ramp does not affect the speed of the toy car.

What are speed and its unit?

Speed refers to the rate of change of position of an object. Speed is measured as the ratio of distance covered by a body to the time in which the distance is covered. Speed is also defined as the rate of distance covered with time. The SI unit of speed is the combination of the basic unit of distance which is the meter and the second basic unit of Time. Thus, the SI unit of speed is meters per second. The formula of speed is

speed = distance time.

Velocity also refers to the speed of the object but in velocity, the object is moving in a specific direction.

According to the graph, there is no effect of the inclination of the ramp on the speed of the toy car but there is a direct effect on the distance of the ramp and the speed of the toy car. We can see in the graph that when we increase the distance of the ramp, the speed of the toy also increases and vice versa.

So we can conclude that there is no effect of the inclination of the ramp over the speed of the toy car.

Which of these is not a function of some membrane proteins A keeping polar molecules out of a cell B receiving messages from other cells C recognizing other types of cells D Catalyzing chemical reactions in the cell

Answers

Membrane proteins are those structures that are joint to the membrane of the cell, which allows it to have communication between its inside and its outside, but they have a limited size, and because of that, they keep great polar molecules outside the cell, also receive messages from neighboring cells, and recognize other types of cells, but they are not involved in the catalyzation of chemical reactions in the cells, since their function is mainly allow the movement of molecules from inside to outside or vice versa, and, as we've seen, also the communication between other cells.

So the answer to this question is D. Catalyzing chemical reactions in the cell, what they don't do.

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.

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.

Using osmosis, explain why hyperglycemid would be clamaging to blood vessel cells.

Answers

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.
