Answer:
Protein B has a higher affinity for ligand C than protein A
Explanation:
Binding affinity is a measure of the strength of the bonds or interactions between a single biomolecule or receptor to its ligand. A ligand is usually a small molecule that binds to a specific receptor.
The receptor is usually a large molecule that contains a specific site for the binding of ligand.
Binding affinity is usually measured by the equilibrium dissociation constant (KD). The equilibrium dissociation constant KD is a ratio of the dissociation and the association of ligand to the receptor. The value of KD is used to evaluate and compare the strengths of bimolecular interactions. The larger the KD value, the more weakly the target molecule and ligand are attracted to and bind to one another.
The higher the dissociation constant (KD), the weaker the affinity is between the interacting molecules, whereas, the smaller the KD value, the greater the binding affinity of the ligand for its target.
Protein B has a KD value of 10⁻⁹ M while Protein A has a KD of 10⁻⁶ M.
Ration of KD of protein B to protein A = 10⁻⁹ M/10⁻⁶ M = 10⁻³
Therefore, protein B has a KD value which is 1000 times smaller than the KD of protein A.
I believe the correct answer is FALSE.
<h2>Explanation:</h2>
The heart is an organ located at the center of the chest in the thoracic cavity and functions to supply blood to and from tissues giving the tissues oxygen and nutrients while taking away carbon dioxide and waste products. It is divided into 4 chambers and 2 chambers are separated by a muscular wall that prevents mixing of the blood.
<h2>Further Explanation:</h2>
Blood enters the heart via the vena cava which is divided into the superior vena cava that recieves blood from the upper region of the body that includes the head, neck and chest while the inferior vena cava recieves blood from the lower extremeties that includes the legs, the abdomen, the pelvic region and the thighs. The blood is deposited into the right atrium and is de-oxygenated. When it is deposited into the right atrium, the change in volume of the atrium and the expansion causes the valve to open and allow the de-oxygenated blood to flow into the right ventricle. The right ventricle then pumps the blood that is de-oxygenated to the lungs via the pulmonary artery which is the only artery that pumps de-oxygenated blood. In the lungs, carbon dioxide is removed and oxygen added to the blood and is taken to the left atrium which pumps the oxygenated blood to the left ventricle and then the left ventricle pumps the oxygenated blood to the rest of the body. The blood is then again taken through the body via the capillaries and the veins pick up the blood that has been removed of oxygen and added with carbon dioxide and transport the blood back to the heart via the vena cava. It enters the right atrium via both the inferior and superior vena cava and the de-oxygenated blood is circulated again to the lungs for oxygenation from the left ventricle.

Answer:
Plants that adapted to the cooler conditions would survive and rapidly evolve into a new species.
Explanation:
<em>The plants will react by evolving through natural selection.</em>
The plant species that do not have the genes to adapt to the rapid change in climate would become extinct while those with adaptive genes will survive, reproduce, and contribute rapidly to the development of future generations.
In other words, natural selection selects for individuals with adaptive genes and ensures that such individuals reproduce more and give rise to future generations with the adaptive gene while individuals that are poorly adapted to the change in climate gradually fade off the population.
Hence, <u>the plants that adapted to the cooler conditions would survive and rapidly evolve into new species</u>.
Answer:
Explanation:
Shutterstock. When the molten outer core cools and becomes solid, a very long time in the future, the Earth's magnetic field will disappear. When that happens, compasses will stop pointing north, birds will not know where to fly when they migrate, and the Earth's atmosphere will disappear
