Corals host dinoflagellate symbionts called expelled, result in coral bleaching because neither the coral nor its symbiont can survive alone, this relationship is called dinoflagellates provide nutrients from the products of photosynthesis which are essential for zooxanthellae survival.
What is endosymbiotic dinoflagellates?The endosymbiotic dinoflagellates are found in the bodies of corals. These endosymbiotic dinoflagellates are called zooxanthellae and are immobile. Being autotrophic, zooxanthellae carry out photosynthesis to produce the organic food required for corals.
Death of endosymbiotic dinoflagellates deprives the coral of organic nutrients leading to their death. This is why the endosymbiotic dinoflagellates are required for survival and productivity of coral reefs.
Therefore, Corals host dinoflagellate symbionts called expelled, result in coral bleaching because neither the coral nor its symbiont can survive alone, this relationship is called dinoflagellates provide nutrients from the products of photosynthesis which are essential for zooxanthellae survival.

Laws change, constitutions get amended, and they do so because changes take place
in society that harbor that necessary change. If you could make a change in West
Virginia, in an Essay giving detail, what change would it be and why?
If I could make a change in West Virginia, the law will be in regards of arms possession by civilians.
Total Ban on arms possession by civilians in West Virginia.West Virginia is known to be a state that gives room for open carry without a permit. If a person is at least 18 years old and has a legal right to possess a handgun under state and federal law, they are permitted to carry a firearm openly without a license. There are some places that are off-limits, such courts and schools.
It is a society that recognizes the right to carry a concealed weapon within the state without first acquiring a concealed handgun license. This law may seems okay for some people, but its negative implications outweigh its advantages.
With the high rise in gun violence, there is therefore the need to amend this law. The Second Amendment does not protect concealed carry of arms, according to opponents of the practice, who also contend that police personnel with the appropriate training should be in charge of ensuring the protection of the public.
Therefore, i believe a total ban should me place on civilians carrying fire arms so as to protect the people from harm.

susan is a consultant for a grocery store chain that wants to open several new stores in the st. louis area. she has selected several sites for the company to consider based in part on projected population growth near those sites. what isolating mechanism does this best illustrate?
The isolating mechanism which best illustrates Susan's consultancy is better expectations of future resource value.
Susan is making an investment in future value thus, the company can gain a competitive advantage by having better expectations of a resource's future value. A company can gain a long-term competitive advantage by consistently setting higher expectations over time.
Isolating mechanism: A steady stream of economic profits and the persistence of intra-industry firm differences over time are both explained by isolating mechanisms, which are also referred to as barriers to imitation (Mahoney and Pandian, 1992). Similar to entry barriers and mobility barriers, isolating mechanisms operate on different levels.
Barriers to imitation that prevent a company from competing are:
1. Better expectations of the value of future resources—investment in future value
2. Path dependence—the options faced are limited by past decisions;
3. Causal ambiguity—the cause and effect of a phenomenon are not readily apparent
4. Social complexity—the interaction of various social and business systems and
5. Intellectual property (IP) protection—a critical intangible resource that can serve as a powerful isolating mechanism. The main types are Trade secrets, designs, patents, copyrights, and trademarks.

In the gluteus maximus, each motor unit controls a _____________ amount of muscle fibers than a motor unit in the eye muscles.
In the gluteus maximus, each motor unit controls a greater amount of muscle fibers than a motor unit in the eye muscles.
The primary hip extensor muscle is the gluteus maximus. It is the largest of the three gluteal muscles which determines the shape of the hips. Eyes need to move with precision and with a high level of control, which is made possible by the fact that there are fewer muscle fibers connected to each neuron. This is the reason why motor unit in gluteus maximus controls a greater amount of muscle fibres than the eye.
Smaller, lower threshold motor neurons in the muscle's small motor units will be more excitable and will fire first to their skeletal muscle fibers, which also tend to be the smallest. This is how eyes work efficiently. On the other hand, limbs requires greater amount of movement and thus have a larger muscle.

more free energy is released during the krebs cycle than during glycolysis, but only 2 moles of atp is produced for each mole of glucose undergoing glycolysis. most of the remaining free energy that is produced during the krebs cycle is used to a) synthesize gtp. b) reduce nad and fad. c) release as heat. d) oxidize pyruvate.
The Krebs cycle releases more free energy than glycolysis does, although only two moles of ATP are created for every mole of glucose that is glycolysis. Reducing nad and fad uses the majority of the free energy that is still created during the Krebs cycle.
What is meant by the Krebs cycle?The second crucial stage of oxidative phosphorylation is the Krebs Cycle, often known as the citric acid cycle. The Krebs cycle converts the energy from the smaller, 3-carbon glucose molecules produced by glycolysis into electron carriers, which are then utilized in the electron transport chain to create ATP.
The tricarboxylic acid (TCA) cycle, also known as the Krebs or citric acid cycle, is the main source of energy for cells and a crucial step in aerobic respiration. The cycle transforms the chemical energy of acetyl coenzyme A (acetyl CoA) into nicotinamide adenine dinucleotide's reducing force (NADH).

The principle of proximity, a Gestalt concept, is used in this differentiation. According to this theory, items that are near together are seen as a group, whereas those that are far apart are seen as individual beings. In the case of a flock of birds, their proximity provides a sense of oneness and causes us to perceive them as a group while they are flying close together. Yet, their proximity is diminished at a great distance, and we see the birds as individual birds flying apart. One of the Gestalt concepts that aid in the organization and comprehension of visual data is the idea of closeness.

In eukaryotes, the citric acid cycle takes place in the mitochondrial matrix. Glycolysis occurs in the cytosol. Electron transport chain includes both the intermembrane space and the inner mitochondrial membrane.
Pyruvate from glycolysis is transported to mitochondrial matrix for the citric acid cycle to take place. The citric acid cycle is where acetyl CoA is modified in the mitochondria to produce energy precursors required for the next step.
The process where electron transport from the energy precursors from the citric acid cycle leads to the phosphorylation of ADP, producing ATP is Oxidative phosphorylation.
