Explanation:
There are three main steps of cellular respiration: glycolysis; the citric acid (TCA) or the Krebs cycle; and the electron transport chain, where oxidative phosphorylation occurs. The TCA cycle and oxidative phosphorylation require oxygen, while glycolysis can occur in anaerobic conditions.
as a pelican flies above the water's surface why must it aim for the fish in slightly different place than fish appears to be located
The reason it must aim for the fish in a slightly different place than where the fish appears to be located is option D: Light waves are refracted as they travel from air to water.
What is the refraction about?Light slows down when it transitions from less dense air into more dense glass or water. The light ray changes direction as a result of the slowing of the light. Refraction is brought on by a change in the light's speed.
We know that when light tends to bends away from the normal when it reaches the air, which is why the pelican must dive in front of the horizontally oriented image of the fish because of the law of refraction.
So, The angle at which the light exits the water from the fish bends it away from the normal, giving the impression that the fish is closer to the surface.

A cell s placed in an isotonic solution. How does the cell aintain homeostasis in this environment
Answer:
If a cell is placed in an isotonic solution, there will be no net flow of water into or out of the cell, and the cell's volume will remain stable.
A cell's volume won't change if it is submerged in an isotonic solution, since there won't be any net water movement in or out of the cell. If the concentration of solutes inside and outside the cell are equal, and the solutes cannot cross the membrane, the solution is isotonic to the cell.
What cell maintain homeostasis in isotonic solution?Equal amounts of solutes are present inside and outside the cell membrane in cells that are isotonic to the surrounding solutions. As a result, a dynamic equilibrium is created, maintaining the cell's condition. All living things need a mechanism to control their interior surroundings. We refer to this as homeostasis.
For animal cells to be in equilibrium, isotonic fluids are required. All living organisms must maintain homeostasis, which is a state of equilibrium. Animal cells don't have a cell wall, thus when there is too much water entering or exiting the cell, it will burst or shrink and die.
Therefore, If a cell is submerged in an isotonic solution, there won't be any net water inflow or outflow, and the volume of the cell will stay constant.

Answer:
One parent has blood genotype BO and the other has blood genotype AO.
Explanation:
There are 4 different genotypes shown, so all 4 "letters" must be utilized. Additionally, the third child has type AB, and since each "letter" comes from a parent, one parent has "A", and the other has "B". Finally, since the second child has type O, and "O" only shows up when the genotype is "OO", that means that each parent must also have "O" in their genotype, which leaves us with one parent having genotype BO and the other with genotype AO.

explain the effect of gases being trapped in the atmosphere
Answer:
This is called the Greenhouse Effect.
Explanation:
The greenhouse effect is the mechanism by which some molecules in an atmosphere contribute to the planet's ability to retain heat. There are two concepts to grasp: two factors: 1) how heat energy escapes from warm objects; and 2) how some gases prevent the heat energy from escaping.
1. How heat energy escapes from warm objects
Anything that is warmer than absolute zero (-273.15 °C) emits electromagnetic radiation, or "glows." That is to say, any warm object radiates electromagnetic waves that carry some of the heat energy along with them as they travel away from the object.
Electromagnetic radiation: What is it? Waves are what move and convey energy through space. The amount of energy that a wave can carry increases with its frequency (waves per second). Low frequency electromagnetic radiation is referred to as "radio." Visible light is a much higher frequency type of electromagnetic radiation. X-rays operate at an even higher frequency.
The range of frequencies that warm objects produce depends on the object's temperature. We can see objects that are really hot glow because they emit a lot of visible light. Although cooler objects don't produce visible light, they nevertheless glow from low frequency electromagnetic radiation that is unseen. The average surface temperature of the Earth is 15 °C, and objects at this temperature emit "infra-red" electromagnetic waves, which have a lower frequency than red light and cannot be seen by human eyes. Since the sun's surface is about 6,000 degrees Celsius hotter than Earth's, it emits visible light. The fact that anything with a temperature above absolute zero glows is similar in many ways.
The Earth is 'glowing' with invisible infrared simply because it is warm. The infra red takes heat energy away from the Earth. It disappears into space.
2. How some gases stop the heat energy escaping
A molecule can vibrate. The tensions between the atoms that make up molecules resemble tiny springs and minuscule balls, respectively. The balls can be rhythmically brought closer together and farther apart by the springs as they compress and stretch. One approach to temporarily store energy is to cause a molecule to vibrate.
When electromagnetic waves strike a molecule, if they are of the proper frequency, the wave's energy can be converted into the vibrational energy of the molecule. In other words, the electromagnetic wave's energy is stored in the molecule. However, it doesn't retain the energy for very long before ceasing to vibrate and converting it back into an electromagnetic wave.
Which frequencies cause the molecule to vibrate depends on its characteristics. The frequencies at which carbon dioxide, methane, and other greenhouse gases vibrate are the same as those of infrared light. Because they don't vibrate at the same frequencies as nitrogen and oxygen molecules, infrared radiation passes right by them. On the other hand, there is a good chance that a carbon dioxide molecule will absorb an infrared wave's energy and momentarily store it as a vibration if it does so.
It's important to note that a vibrating molecule can eventually emit a wave that travels in any direction, including up, down, left, right, forward, and backward. Where the initial wave was going is irrelevant.
3. Putting it all together
Electromagnetic radiation, or heat, is constantly emitted from the Earth's surface.Carbon dioxide, methane, and other molecules with the proper vibrational frequencies absorb infrared waves that are traveling out into space, and their energy is momentarily stored as a vibration.The infrared wave that results from the vibration's transformation back into a vibration can travel in any direction, including back towards Earth. Its energy will be reabsorbed by the Earth if it comes in contact with the surface.Without "greenhouse gases," all of the heat energy contained in the infrared would be carried away into space. Because of the obstruction caused by greenhouse gas molecules, some infrared radiation is reemitted back toward the Earth, replenishing some of the heat energy lost.More heat energy will be conserved if we add more greenhouse gas molecules to the atmosphere. The Earth's surface will be hotter the more heat energy there is.Thanks.
The enzyme hexokinase catalyzes the conversion of glucose to glucose-6-phosphate, which is an important step in glycolysis. The reaction involves the transfer of a phosphate group from atp to glucose. Either a glucose molecule or a water molecule can fit in the active site of hexokinase. The presence of a water molecule in hexokinase’s active site would result in the hydrolysis of atp to adp instead of the conversion of glucose to glucose-6-phosphate.
Hexokinase solely changes glucose into glucose-6-phosphate; it does not catalyse the breakdown of ATP. Due to this compatibility, hexokinase binds to glucose but not to water, and the structural change is necessary for hexokinase to become catalytically active.
Adenosine triphosphate is utilised and stored as energy at the cellular level (ATP). The structure of ATP, a nucleoside triphosphate, is made up of adenine, ribose, and three serially bound phosphate groups. A substance that can be used as a catalyst to accelerate a reaction without being consumed. Catalysts often reduce a process's activation energy or change its mechanism.

When in a complex with ________, the cap protein binds to the cap site and ________ the expression of the lac operon.
compound including glucose The lac operon's expression is changed when the CAP protein attaches to the CAP site.
Bound RNA polymerase is assisted in binding to the lac locus promoter by CAP. There must be lactose available: The lac promoter will be freed from the operator if lactose is accessible by binding of allolactose. This enables the transcription of the operon by RNA polymerase to proceed on the DNA. Two distinct proteins govern the function of the promoter, which manages the lac operon's expression. One of the proteins stops RNA polymerase from trancribing (negative control), while the other improves RNA polymerase's ability to attach to the regulator (positive control). A particular DNA sequence is located upstream of the lac locus operator and promoter, where CAP and cAMP interact. The CAP-cAMP complex subsequently binds to this DNA sequence.
