summarize the importance of stem cells

Answers

Answer:

Stem cells can become almost any cell in the human body.

Explanation:

This is important because in embryonic development, the body uses stem cells to form each individual part. For example, a single stem cell could become a heart cell, or brain cell, or a blood cell, or more. This is also important for possible treatments. In order to heal damaged or diseased bone tissue, blood stem cells can be taken out of the same person and used to fix the tissue. This allows for a lower rejection rate sense the cells used to fix the tissue were already part of the person's body.

There is a relationship between the number of prey organisms and the number of predator organisms in an ecosystem. Identify this relationship and explain how it occurs.

Answers

Answer:

This relation should be called Predator-Prey relationship. In the predator prey relationship, one species is feeding on the other species. The prey species is the animal being fed on, and the predator is the animal being fed. they affect the success and survival of each other’s species. The predator prey relationships greatly affect the populations of each species, for example if we take lynx as predator and hare as prey after some time the population of hare will start declining and population of lynx will increase because hare is being EATEN and lynx is the predator here.

Which of the following is an example of a non contact force

Answers

Answer:

Gravity, Electrostatic force, Magnetic force

Explanation:

A non-contact force is a force that is applied to an object by another object without contact. Gravity, electrostatic force, and magnetic force all don't need two objects to be touching in order for them to work.

On the other hand, an example of a contact force is friction, because it can only occur if two objects are touching. If you want to tell the difference between a contact and non-contact force, just ask yourself if it can occur if the two objects are not touching. If it can occur while two objects aren't touching, it is non-contact, and if it can't, it is contact.

All the options given describe a force that involves contact except for the force exerted by magnets. Thus, the correct option is C.

Magnetic force is the force exerted by magnets. It can be described as the effect exerted on a charged particle due to the magnetic field of the other particle.

It is a consequence of the electromagnetic force, which is caused due to the movement of electrically charged particles.

Two objects that are oppositely charged will have a magnetic force of attraction, whereas two objects that have the same charge will have a magnetic force of repulsion.

Photosynthesis is the process of preparing food in the presence of light, water, and carbon dioxide. Photosynthesis can be light-dependent or light-independent reactions.

The correct answer is:

Option A.  Yes, as reactant A.

The mechanism can be explained as:

1. Light-dependent reactions convert light energy into chemical energy.

2. The light-dependent reactions require water and light to yield oxygen, hydrogen, and energy molecules.

3. The light is used to break down the molecule of water into oxygen and hydrogen when the light strikes the thylakoid.

4. The ATP is generated in the stroma of the thylakoid membrane. The excited electrons released during the splitting of water is utilized to produce high-energy molecule.

Thus, water molecule should be used as a reactant because it yields products.

Under certain external conditions, a person will perspire a great deal. For which internal condition does this response
primarily provide homeostasis?
water balance
electrolyte balance
temperature balance
energy balance

Answers

Answer:

Perspiration provides homeostasis to the internal condition of temperature balance.

Explanation:

Perspiration occurs as a consequence of the increase in environmental temperature, which at the same time produces an increase in body temperature.

The high body temperature produces a stimulus that reaches the thermoregulation center of the central nervous system, which produces a response transmitted through the sympathetic nervous system, causing the sweat glands to increase the production of sweat.

The sweat that covers the skin is capable of acting as a physical agent to lower the temperature, a mechanism of thermal regulation that contributes to temperature balance.

The other options are not correct because:

Water and electrolyte balance is done at the renal level. The energy balance depends on the food intake and the amount of energy used.

What happens to glucose which enters nephron along with filtrate

Answers

Answer:

it goes down the renal tubule by the action of cilia. The tubular cells absorb glucose, amino acids, salts, etc. These are then passed into the capillary blood cells using the process of diffusion.

When glucose enters nephron along with filtrate, it goes down the renal tubule by the action of cilia. The tubular cells absorb glucose, amino acids, salts, etc. These are then passed into the capillary blood cells using the process of diffusion. Selective reabsorption is the process whereby certain molecules (e.g. ions, glucose and amino acids), after being filtered out of the capillaries along with nitrogenous waste products (i.e. urea) and water in the glomerulus, are reabsorbed from the filtrate as they pass through the nephron. Glucose that enters the nephron along with the filtrate after passing through the glomerulus, passes from the tubule of nephron where it is selectively reabsorbed and sent back to blood.
The filtered part of blood that is collected into the Bowman's space is called glomerular filtrate . ... Once the filtrate passes through the proximal convoluted tubule , the primary site of absorption, 100% of the glucose is reabsorbed back into the blood, including other nutrients and molecules. Nephric filtrate goes to Bowman's capsule when glucose comes out from it. The filtrate then passes through the tube where the blood capillaries absorb glucose. The capillaries of the blood carry glucose to all the cells of the body. Reabsorption. Reabsorption takes place mainly in the proximal convoluted tubule of the nephron . Nearly all of the water, glucose, potassium, and amino acids lost during glomerular filtration reenter the blood from the renal tubules. Following a meal, glucose utilization by the kidney increases. Normally each day, ∼180 g of glucose is filtered by the kidneys; almost all of this is reabsorbed by means of sodium–glucose co-transporter 2 (SGLT2), expressed in the proximal tubules.

describe the arrangement of water molecules in a solid, liquid and gas form. how does the movement of the molecules differ in each form? Describe the bonds when the molecules are in motion.

Answers

Answer:

In a solid, the molecules are tightly packed in neat rows and they vibrate quickly. Solids have a definite shape and volume. In a liquid, the molecules have more energy and they move around more freely. Liquids have a definite volume but they don't have a definite shape. The molecules in gases are spread apart and move very freely with very much energy. Gases do not have a definite shape or volume.

Hope this helps!

:)

The description of the arrangement of water molecules and their motion in a solid, liquid and gas form and how they differ in each form is as follows:

Solid state is characterized because the molecules that compose it are very close together by a network of covalent bonds and in more or less fixed positions; this makes the distance between the particles practically unchanged.

This is due to the fact that the attractive forces are very intense and the particles are only free to carry out small vibrations and that is why solids have constant shape and volume.

In the liquid state, the forces between the particles are weaker than in the solid state, which allows the particles to have some freedom of rotation and translation, due to mobile ions.

Besides the vibration; they can slide over each other and maintain a constant mean distance between them without being fixed.

For this reason, liquids, unlike solids, take variable forms, depending on the container that contains them and they can also flow easily.

Their similarity to solids is based on the fact that, like the solids, they are difficult to compress and have constant volume.

In the gaseous state the attractive forces are practically zero and the particles acquire a total mobility of vibration, rotation and translation,

Being the distance between the molecules much greater than the one that they have in solid or liquid state and, in addition, variable at all times.

Gases, unlike solids and liquids, can be easily compressed or expanded and also take the shape of the container that contains them, occupying the entire available volume.

Therefore, the intensities of the interactions or cohesion forces of water molecules are not the same in solids, liquids and gases, the effects of movement and interaction on the arrangement of the particles are opposed, resulting in different states of aggregation.

answer the following questions regarding the organism that the product is derived from (reasonable guesses or
speculation is ok):
1. What is the organism?
2. Where does the organism live?
3. Briefly characterize the ecosystem that the organism lives in.
4. Provide one example of how the organism depends on another organism.
5. What are some threats to the organism in the ecosystem?
Speculate on how your life would be affected if the organism became extinct.

Answers

Answer:

1. An organism is a individual animal, plant, or single-celled life form.

2. Habitat, place where an organism or a community of organisms lives, including all living and nonliving factors or conditions of the surrounding environment. Like a forest, lake, coral reef, desert, towns or cities.

3. An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors are animals, trees, plants, and abiotic factors are things that have never been alive. So rock rivers, ponds, man made objects.

4. When a organism depends on another is called symbiotic relationships. There are three different types of symbiotic relationships: mutualism, commensalism, and parasitism. Mutualism: both partners benefit. An example of mutualism involves goby fish and shrimp. The shrimp maintains a burrow in the sand in which both the fish and shrimp live. When a predator comes near, the fish touches the shrimp with its tail as a warning. Then, both fish and shrimp retreat to the burrow until the predator is gone.

5. Pollution(water&air), deforestation, UV Radiation, invasive species.

If an organism went extinct the next generation won't ever be able to see those organisms. If an organism we eat went extinct we would have one less food source which is something that really does not need to happen in today world.

Answers

Answer:

The cell membrane is selectively permeable, which controls the movement of materials in and out of the cell by passive and active transport.

Explanation:

According to this question, animal cells are made up of the following contents: 90% water and 10% protein, carbohydrates, nucleic acid, lipids and other molecules. The cell regulates this internal composition in a stable way via a process called HOMEOSTASIS.

The animal cell is able to regulate or maintain a stable internal composition by the possession of a selective permeable membrane called CELL MEMBRANE. The cell membrane is semi-permeable in the sense that it allows the entry of some molecules into and out of the cell and blocks others.

Some molecules are allowed by the cell membrane without the need for energy input in a transport called PASSIVE TRANSPORT while some requires energy input in a transport called ACTIVE TRANSPORT.
