Answer:
Explanation:
Kepler's First Law: The orbit of a planet around the Sun (or a satellite around a planet) is not a perfect circle. It is an ellipse—a “flattened” circle. The Sun (or the center of the planet) occupies one focus of the ellipse. A focus is one of the two internal points that help determine the shape of an ellipse. The distance from one focus to any point on the ellipse and then back to the second focus is always the same.
The law of ellipses suggests that the orbit of planets is not circular but ellipses
Therefore your answer would be; Ellipses
Answer:
The law of ellipses suggests that the orbit of planets is not circular but elliptical.
Explanation:
Kepler's first law (the law of ellipses) explains that the orbit of the planets around the sun is not in a circular but elliptical path.
Which of the following molecules provides the greatest energy storage capacity in animal cells?
A. starch
B. proteins
C. triglycerides
Triglycerides are the molecules that provide the greatest energy storage capacity in animal cells.
What is triglycerides?Triglycerides are the type of fat also called lipids that are found in your blood. When you eat, your body converts calories that it does not need to use into triglyceride molecules. The triglycerides are stored in the fat cells. After the hormones release triglycerides for energy between eating. Sugary food, sweat drinks, saturated fats, refined grains, alcohol, and foods having high-calorie all lead to high levels of triglycerides. The healthcare provider classifies high triglyceride levels i.e. Mild levels as 150-199 mg/dL, Moderate level has 200-499 mg/dL, and Severe levels has Greater than 500 mg/dL. Very high triglycerides may cause blocking of the blood supply to the heart or brain. Symptoms of lower blood supply to your heart could be chest pain.
So we can conclude that option C is the correct answer.

Although animal nervous systems differ in complexity, their nerve cells are still remarkably similar
a. True
b. False
It is true that, Despite the fact that the complexity of animal nervous systems varies, their nerve cells are still remarkably similar.
Nearly all multicellular animals have nerve systems, but their complexity varies greatly. Sponge and the tiny blob-like placozoan and mesozoan organisms are the only multicellular animals without a nervous system. A diffuse nerve net makes up the nervous systems of ctenophores (comb jellies) and cnidarians (such as anemones, hydras, corals, and jellyfish). With the exception of echinoderms and a few worm species, all other animals have a nervous system that includes a brain, a central cord (or two parallel cords), and nerves that radiate from the brain and central cord.
The nervous system's most fundamental roles are to direct an organism's movement and to influence its surroundings (such as through pheromones). Signals are sent from one cell to another or from one part of the body to another to accomplish this. Signals that travel to muscle cells trigger the activation of muscles and signals that travel to endocrine cells triggers the release of hormones into the bloodstream or other internal fluids are the sources of the output that the nervous system produces.

3. How might the changes that you identified affect the protein’s structure?Example: The change would likely have no effect. Neither valine and isoleucine would promote hydrogen bonding with water, because their R groups are nonpolar and thus hydrophobic.Changes spotted in the previous question:1. Valine changed for Isoleucine: there was not a change in the chemical properties, because both amino acids have non-polar chains2. Valine changed for Alanine: there was not a change in the chemical properties, because both amino acids have non-polar chains3. Glutamate changed for Alanine: there was a change because the aminoacidic chain lost their electronegativity4. Glutamate changed for Aspartate: there was not a change because the aminoacidic chain kept it's electronegativity.1) _______________________________________________________________2) _______________________________________________________________3) _______________________________________________________________4) _______________________________________________________________
In the previous exercise we spotted that in the sequences there were at least four changes in the aminoacidic sequences:
1. Valine changed for Isoleucine: as indicated by the very exercise, there wouldn't be a negative effect, because both amino acids have hydrophobic radical groups.
2. Valine changed for Alanine: like in the previous case, there wouldn't be a negative effect, because both amino acids have hydrophobic radical groups.
3. Glutamate changed for Alanine: there would be a change in the protein structure because Glutamate can form hydrogen bonds, and Alanine doesn't.
4. Glutamate changed for Aspartate: there wouldn't be a change in the protein structure because both amino acids can form hydrogen bonds.

What happens to oil when it enters the water? Explain how this property of oil contributes to the effects of oil spills in ocean ecosystems.
Oil is insoluble in water. When oil spills in the ocean it creates great "oil islands". These islands are devoid of nutrientes, oxygen or any compound normally found in water. So they represent a massive perturbation to marine biota. Beside this oil disrupts, and frequently kills, marine fauna, such as water birds, and cetaceans.
Why isn’t the mitochondria classified as part of the endomenbrame system
The endomembrane system encompasses the organelles that mediate the importa, export of molecules, that is, the transport of molecules from the environment to the cytoplasm and from the cytoplasm to the environment, respectively. The organelles that participate in such activities are the endoplasmic reticulum, the golgi apparatus, vacuoles and the cell membrane. Mithocondria's main purpose is energy production through oxidation of the carbohydrates/lipids we consume, thus, it is not related to molecule transport, and it can not be part of the endomembrane system.
A scientist claims that Elysia chlorotica, a species of sea slug, is capable of photosynthesis. Which of the following observations provides the best evidence to support the claim?1) Elysia chlorotica grows in the dark when food sources are available.2) Elysia chlorotica grows faster when exposed to light than when placed in the dark.3) Elysia chlorotica will die if not exposed to light.4) Elysia chlorotica grows when exposed to light in the absence of other food sources.
The observation which best supports the claim that Elysia chlorotica is capable of photosynthesis is number 4. The ability to photosynthesize doesn't mean it won't be able to eat other food sources when abailable, but that it will be able to survive and grow in abscense of food sources if it is exposed to light, as light is necessary to obtain the energy for the process of photosyntesis.

The electrical energy consumed is 0.3 kWh. Electrical energy is energy related to forces on electrically charged particles and electrically charged particle movement.
What is electrical energy?Electrical energy is the ability of an atom's charged particles to perform an action or move an object. Electrical energy is produced by the movement of electrons from one atom to another. When you plug in a toaster or a cellphone charger into a wall outlet, electrical energy is used to power those devices. Electricity can be either kinetic or potential.Batteries, lightning, and electrical charges moving through a wire plugged into a wall socket to power electrical appliances such as televisions and computers are all examples of electrical energy. It now even powers many of our automobiles. It can be found in the clouds above you during a storm even if you travel to the most remote parts of the planet.Therefore,
The amount of electrical energy consumed can be calculated as follows:
E = Pt

True or False: Blood sugar would be lower than normal if alpha cells constantly secreted insulin.
Answer:
The human body wants blood glucose (blood sugar) maintained in a very narrow range. Insulin and glucagon are the hormones which make this happen. Both insulin and glucagon are secreted from the pancreas, and thus are referred to as pancreatic endocrine hormones. The picture on the left shows the intimate relationship both insulin and glucagon have to each other. Note that the pancreas serves as the central player in this scheme. It is the production of insulin and glucagon by the pancreas which ultimately determines if a patient has diabetes, hypoglycemia, or some other sugar problem.

There is a key difference between aerobic respiration (cellular respiration) and anaerobic respiration (fermentation). Explain this difference and what is the overall equation for aerobic cellular respiration.
The key difference is that aerobic respiration requires oxygen, and anaerobic respiration does not.
Aerobic respiration in a cell is when glucose breaks down with help of oxygen and yields carbon dioxide, water, and with the release of energy. Thus end products are [tex]CO_2}[/tex] and [tex]H_{2}O[/tex] .The process of releasing energy takes a much longer time. Example it occurs in plants and animals.
Anaerobic respiration in a cell, is the process of breaking down glucose without the use of oxygen then it yields to the end products [tex]CO_{2}[/tex] (carbon dioxide), alcohol and energy. It is a fast process. Example human muscle cells, and bacteria.
The equation for aerobic cellular respiration
[tex]C_{6} H_{12} O_{6} + 6O_{2}[/tex] ⇒ [tex]6CO_{2} + 6H_{2}O[/tex] + ATP(energy)
Glucose + oxygen ⇒ carbon dioxide + water +energy.
