energy is realsead when which bonds of ATP are broken?
Hi friend! Hope you find this response helpful! :)
When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP). Likewise, energy is also released when a phosphate is removed from ADP to form adenosine monophosphate (AMP).
How is the number of bonds carbon can make related to its ability to form molecules with many different shapes?
because each carbon atom can form four chemical bonds to other atoms and because the carbon atom is just the right or small size to fit in comfortably as parts of very large molecules.
The number of bonds carbon can make is related to its ability to form molecules with many different shapes because: it can form four (4) covalent bonds, rings, straight chains, and wrench chains.
Carbon refers to a non-metallic and tetravalent chemical element which is represented with the chemical symbol C and it has an atomic number (number of protons) of six (6).
Generally, carbon (C) has the ability to form chains that are almost unlimited in length because an atom of carbon can bond to other carbon atoms.
This ultimately implies that, carbon (C) can form molecules with many different shapes as a result of the number of bonds carbon it can make.
Hence, the ability of carbon (C) form molecules with many different shapes is simply because of the following:
Carbon (C) can form four (4) covalent bonds.It can form rings.It can form straight and wrench chains.Carbon (C) atoms can bond to other carbon atoms.Read more: https://brainly.com/question/17574947
Living organisms evolved in a world where they were constrained by the laws of physics and chemistry. Describe the two laws of thermodynamics and explain how each law impacts the structure of an ecosystem's food chain as energy flows from one trophic (feeding) level to the next
Answer:
The laws of thermodynamics are important unifying principles of biology. These principles govern the chemical processes (metabolism) in all biological organisms. The First Law of Thermodynamics, also known as the law of conservation of energy, states that energy can neither be created nor destroyed. It may change from one form to another, but the energy in a closed system remains constant.

Currently, most organs that are harvested for transplant are transported from the donor to the recipient packed in ice and must be implanted within a matter of hours. How is organ culture an improvement on this transport method? Organs that are packed in ice can be damaged by frostbite during transit. Cultured organs can be kept alive for several weeks before transplant. Extra culture medium is easier and cheaper to transport than extra ice. Organ cultures can be shipped as cargo rather than hand delivered.
The organ culture is an improvement on this transport method as cultured organs can be kept alive for several weeks before transplant.
What do you mean by an Organ transplant?It is a method to place a specific organ that is taken from the body of another individual. The doctors remove an organ from another person and place it in your body.
Every organ can not behave in the same way on the outside of the body, so they are kept in cultured solution to function properly and kept alive. Putting the organs in a cultured solution reduces the chances of organ rejection.
Therefore, the organ culture is an improvement on this transport method as cultured organs can be kept alive for several weeks before transplant.

Which of the following are narrow blood vessels that restrict blood flow and have thin walls that allow gas exchange? Alveoli Veins Arteries Capillaries.
Arterioles are narrow blood vessels that restrict blood flow and Capillaries have thin walls that allow gas exchange.
What is blood vessels?Blood vessels are channels that carry blood throughout your body. They help to transport oxygen to vital organs and tissues, and also remove waste products. Blood vessels include veins, arteries and capillaries.
Veins bring blood to the right side of your heart.
Arteries branch into smaller vessels called arterioles. Both arteries and arterioles are very flexible. They get bigger or smaller to help maintain your body's blood pressure.
Capillaries have thin walls that allow oxygen, nutrients, carbon dioxide and waste products to pass through, to and from the tissue cells.

Maintaining homeostasis involves many processes. One of these includes the excretion of waste. Our kidneys work very hard to filter blood of waste products and control how much water is kept in the body. The waste products and water make up urine. A dehydrated individual would have a concentrated urine that's a darker yellow in color than that of a healthy urine. Why is that?
Answer:
Please find the explanation below
Explanation:
As rightly said in this question, the kidney is the major excretory organ in our (human) system, which also helps maintain homeostatic balance between water and waste products. According to the question, the kidneys function to filter blood of waste products and control how much water is kept in the body.
Since urine is a mixture of the removed waste and water, a concentrated urine with a dark yellow color than normal indicates that the involved individual is DEHYDRATED i.e. low in water content of the body and hence needs water.
The urine of this dehydrated individual is this DARK YELLOWISH COLOUR because the kidney RETAINS THE SMALL AMOUNT OF WATER PRESENT IN THAT INDIVIDUALS BODY which ought to make the person's urine diluted, hence, the urine contains more of waste products (urea) and less of water, making it appear darker yellow than that of a healthy individual.
Which action may increase the flask’s carrying capacity for rotifers?
A. decrease the number of microorganisms
b. introduce water fleas
c. decrease the size of the flask
d increase the number of microorganisms
The action that may increase the flask's carrying capacity for rotifers would be to decrease the number of microorganisms in the flask.
Carrying capacityThe carrying capacity of an environment refers to the maximum number of organisms of a particular species that the environment can support based on the resources it has.
Rotifers and microbes growing in the flask mean that both species would have to compete for the resources present in the flask. This competition will limit the reproductive capacity of each species.
As the population of the species decreases, the growth of the other is favored due to less competition.
With rotifers growing alone in the flask, there would be less competition for resources and more population growth.

When the level of carbon dioxide in the blood is too high, the excess carbon dioxide reacts with water and produces carbonic acid. the carbonic acid causes the blood ph to become more acidic. when the blood ph becomes too acidic, chemoreceptors in the brain instruct the body to react and maintain homeostasis in blood ph. which of these responses by the body would eliminate the excess carbon dioxide and help maintain homeostasis in blood ph?
Answer: Breathing more deeply and frequently
The carbonic acid causes the blood ph to become more acidic. when the blood ph becomes too acidic, chemoreceptors in the brain instruct the body to react and maintain homeostasis in blood ph.
What stops functioning of the enzymes?At a pH too far from 7.4, enzymes in the blood will stop functioning properly. The pH of blood is regulated 7.35 and 7.45. pH shows acid-base balance in the body and maintains a healthy balance of acidity and alkalinity.
Balance of acid-base provides optimum condition to enzymes to perform proper function. As, enzymes required optimum pH range for functioning properly, pH too far from 7.4 can denature the enzymes. Enzymes will lose its shape and will not function properly at high pH.
When the level of carbon dioxide in the blood is too high, the excess carbon dioxide reacts with water and produces carbonic acid. the carbonic acid causes the blood ph to become more acidic. when the blood ph becomes too acidic, chemoreceptors in the brain instruct the body to react and maintain homeostasis in blood ph.
Therefore, The carbonic acid causes the blood ph to become more acidic. when the blood ph becomes too acidic, chemoreceptors in the brain instruct the body to react and maintain homeostasis in blood ph.
