Describe the process of positive feedback and how it maintains homeostasis.
(100 points)
Answer:
Homeostasis is the tendency to resist change in order to maintain a stable, relatively constant internal environment. Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points
Explanation:
What is the role of ATP when large molecules need to be transported across the cell membrane against the concentration gradient?
The bond between the phosphate groups is broken to store energy.
The bond between the phosphate groups is broken to release energy.
Bonds are formed between the adenine and the ribose to store energy
Bonds are formed between the ribose and the phosphate to release energy.
Answer:
b. the bond between the phosphate groups is broken to release energy
Explanation:
Phosphate groups are negatively charged => there is a pull between the two groups=> it's easy to break this bond & ATP is unstable
=> ATP has a lot of free energy
breaking the bond between phosphate groups makes the molecules more stable (aka contains less free energy)=> delta G <0
=> breaking this bond releases energy
the energy released by ATP is then used to transport large molecules against the concentration gradientThe bond between the phosphate groups is broken to release energy. This energy helps in the transport of molecules across the cell membrane against the concentration gradient.
ATP is also called as the energy factory for the cell. It is also required for various metabolic processes within and outside the cell. It has a role in transfer of macromolecules like proteins, lipids, and other into and out of the cell. It is difficult for molecules to be transported into and out of the cell across a cell membrane against a concentration gradient for this energy in the form of ATP is required. When the hydrolysis of the molecule of ATP occurs it releases the phosphate group along with the release of energy this energy is necessary for the active transport of molecules against the concentration gradient across a cell membrane. Hence, the bond between the phosphate groups is broken to release energy. This energy helps in the transport of molecules across the cell membrane against the concentration gradient.Learn more about ATP:

A doctor treats a patient with a skin condition with different creams to see which is most effective. What is the independent variable?
1. Skin Creams
2. Skin Conditions
Answer:
1. Skin Creams
Explanation:
An independent variable is the only variable that is changed while the rest is kept the same. In this setup, the doctor is using different creams on the same patient with the same skin condition so the independent variable is the skin cream and not the skin condition.
g When an oxygen molecule diffuses from the air in the lung into the plasma in a capillary in the lung, how many times does it have to diffuse through a plasma membrane before reaching the plasma
Answer:
The answer is 2.
Explanation:
When oxygen gets into the lungs, it first needs to diffuse through the alveoli and into the blood. Then through the veins and capillaries, it diffuses into all the calls in the body. It does so quite easily because it is a nonpolar and a very small molecule with a low concentration inside the cell. This gives it the ability to diffuse easily through the cell membrane.
So the number of times that oxygen has to diffuse through a plasma membrane is two.

Which role does photosynthesis play in the flow of energy? (1 point)
Photosynthesis converts radiant energy to chemical energy to be used by organisms in the food chain.
Photosynthesis is how plants break down glucose to use for energy.
Photosynthesis allows plants to create energy for themselves to store and use for metabolism.
Photosynthesis provides radiant energy to all the organisms in the entire food chain.
Answer:
Radiant energy transformation that takes place during photosynthesis
Explanation:
Radiant energy transformation that takes place during photosynthesis
Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy used to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as cellular respiration
Brainliest please
Photosynthesis converts radiant energy to chemical energy to be used by the organisms in the food chain .
What is photosynthesis?
It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy through the process of cellular respiration.
Some of the energy which is converted is stored in molecules of carbohydrates like sugar and starches which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.
The process begins with proteins absorbing light energy which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.

Remember that we see the color of objects because that color bounces off the object and back to our eyes. The other colors are soaked up by the shirt like a sponge. Why do you think the green light is the least effective color to give plants energy to grow?
If the light color is red or purple then the plant will absorb some amount of energy from the light, Green light is the least effective for plants as the plants are themselves green due to the presence pigment Chlorophyll in chloroplast.
what is function of chloroplast ?
Chloroplasts are the membrane bound cellular organelle present in photosynthetic organism like plants and algae, observed in mesophyll cells of leaves and contain a high concentration of chlorophyll pigment which absorb sunlight.
It has extra-nuclear semiautonomous DNA and make food by the process of photosynthesis by absorbing sunlight into chemical energy.
It also involve indirectly in the process of generation of carbon and sugar molecule during the Calvin Cycle or dark reaction of photosynthesis.

Chlorophyll absorbs energy from blue- and red-light waves and reflects green-light waves during photosynthesis, giving the plant its characteristic green color.
What is the effect of green light in plants?Other pigments, such phycoerythrin, can effectively absorb green light to promote photosynthesis. Additionally, green light can encourage stem elongation, which boosts plant light absorption.
Despite being the visible spectrum's least effective wavelength for photosynthesis, green light is nonetheless helpful and affects plant morphology.
One might occasionally hear that plants reflect green light rather than using it for photosynthesis.
Therefore, green light is the least effective color to give plants energy to grow.

Forest butterflies are often brown. This helps them to
Answer:
Avoid predators
Explanation:
Organisms often mimic their surroundings to escape the predators. This technique is also called camouflaging.
Forest butterflies have also adopted several structural adaptations to avoid predators. Many of them have brown wings with jagged edges so that they resemble dried leaves. In this way, they blend with their surroundings, especially the forest floor, and go unnoticed. On the other hand, butterfly larvae are green in color so that they resemble the leaves on which they feed and avoid predators.

Answer:
Brain cancer is an overgrowth of cells in your brain that forms masses called tumors. Cancerous, or malignant, brain tumors tend to grow very quickly. The symptoms of brain cancer depend on the size and location of the tumor.
Common brain cancer symptoms include:
headaches that are usually worse in the morning
nausea
vomiting
a lack of coordination
a lack of balance
difficulty walking
memory lapses
difficulty thinking ,speech problems
.Many of the symptoms of brain cancer are also caused by other, less serious conditions. There’s no need to panic if you’re experiencing these symptoms, but it’s a good idea to visit your doctor to have your symptoms investigated, just in case.
