Answer:
The correct answer is option B, that is, an endoskeleton evolved to enclose the dorsal nerve cord, which develops from the notochord.
Explanation:
It has been discovered that the ancestors of the modern-day fish were vertebrate chordates. The vertebrate chordates are considered to have evolved from the invertebrate chordates that are identical to the present day tunicates. It has been found that in vertebrates the endoskeleton has evolved to encompass the dorsal nerve cord that has been developed from the notochord (a characteristic of invertebrates).

how are the functions of the endocrine system and nervous system similar?
Answer:
It's similar to the nervous system in that it plays a vital role in controlling and regulating many of the body's functions. However, while the nervous system uses nerve impulses and neurotransmitters for communication, the endocrine system uses chemical messengers called hormones.
Do copd sufferers die of respiratory causes or other causes?
Answer:respitory cuz
Explanation:e
I think its B? Can someone explain it to me tho
Explanation:
I think it should be C because increase in temperature increases molecular motion. Therefore the speed of the moving molecules of both enzymes as well as the substrate will be accelerated. This
will enhance the colliding probability for both enzyme active sites and substrate molecules and more collisions occur between the enzyme active sites and substrate molecules generate greater chances for the reaction to occur. This can continue up to a certain point, after which there is a rapid decline in enzyme activity. This point is referred to
as optimum temperature. When the temperature increases beyond the optimum temperature, the hydrogen bonds, ionic bonds and other weak chemical bonds of enzyme active sites may be disrupted.
This will result a change in the shape of the active site of enzyme which will alter the complementary nature of the active site of enzyme molecules. Therefore, the
complementary binding of enzyme active sites and substrate molecules will be prevented. The above event is called as denaturation of enzyme molecules.
Therefore the rate of enzyme catalyzed reaction or in this case, photosynthesis will start to decline when the temperature increases beyond the optimum temperature and stops completely at certain
temperature, although rate of collision will keep on increasing.
a population distribution pattern that can indicate predation is
Answer:
clump
Explanation:
A population. This type of pattern. This type all better is seen in and seen in species. To prevent a species two prevent radiation radiation. They remain in groups. They remain in groups to remain safe to remain safe from predation from regulation. So climb to distribution. So Klump distribution. This tribute to shin indicates indicates relation random distribution distribution is seen when is seen. Yeah, this does not indicate tradition. This does not indicate relation uniform distribution, uniform distribution is seen more in plants and seen loan in Lawrence rather than animals rather then animals. Again, this does not indicate traditions. This does not indicates tradition. Basin distribution is not relevant, not relevant according to according the ocean given ocean. So that's why this option is incorrect. So all options are incorrect except a option that is Klump and a option is got it. That is clumps.

Most of Earth's energy comes from the Sun. Where does the rest come from?
a. internal heat
b. nuclear fusion
c. biomass
d. fossil fuels
Explain
Answer:
The answer is nuclear fusion
Explanation:
Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun's core and fuse to create a helium atom.

How is water split into hydrogen and oxygen during photosynthesis?
Explanation:
The chlorophyll's donated electrons need to be replaced, and these electrons come from the splitting of water. In a process called photolysis ('light' and 'split'), light energy and catalyst s interact to drive the splitting of water molecules into protons (H+), electrons, and oxygen gas.

Where in the cell would you expect to find the greatest activity of the pyruvate dehydrogenase complex?
Answer:
Mithochondria
Explanation:
In eukaryotes, the pyruvate dehydrogenase complex, like the enzymes for citric acid cycle and oxidation of fatty acids, is located in the mitochondrion, where is associated with the surface of the inner membrane facing the matrix.
In the cell, mitochondria are the place where it expects to find the greatest activity of the pyruvate dehydrogenase complex.
What is the pyruvate dehydrogenase complex?The three-enzyme complex known as the pyruvate dehydrogenase complex (PDC) is responsible for pyruvate carbonylation, which converts pyruvate to acetyl-CoA.
This complex connects the glycolysis metabolic pathway to the citric acid cycle by allowing acetyl-CoA to be used to perform cellular respiration.
The enzyme pyruvate dehydrogenase catalyzes the reaction between pyruvate and a lipoamide, which yields acetylated dihydrolipoamide and carbon dioxide. The process requires the coenzyme thiamine pyrophosphate.
Therefore, the site where you find the greatest activity of the pyruvate dehydrogenase complex is mitochondria.

what is the function of circuit breakers and fuses?
Answer:
Fuses and Circuit Breakers both serve the same purpose – which is to protect electrical circuits by preventing overloads that can cause fires. They both interrupt the flow of electricity, but in very different ways from each other. While a fuse is made of a piece of metal that melts when overheated, circuit breakers on the other hand, have internal switch mechanisms that can be tripped by an unsafe surge of electricity.
Fuses can be quicker for interrupting the flow of power, but when they melt they must be replaced; circuit breakers on the other hand just need to be reset. When comparing the two, we’ll take a look at some of the major advantages and disadvantages between fuses and circuit breakers to distinguish between them.
