Answer: photosynthesis
Explanation:
photosynthesis
Plants use energy from sunlight to turn water and carbon dioxide into an energy-rich sugar called glucose. This process is called photosynthesis, which means “making things with light”. Photosynthesis takes place inside capsules in the leaf cells, called CHLOROPLASTS.
What are three types of freshwater wetlands?
Freshwater wetlands are ecosystem affected by inundation (permanently or temporary). The three major types are swamps (uncultivated low-lying ground where water collects), marshes (low-lying and waterlogged land, flooded in wet seasons or at high tide) and bogs (wet muddy ground that's too soft to support a heavy body).

Equation A hair dryer is
rated at 1,200 watts. If you
use the dryer for 0.25 hours,
how much electric energy do
you use?
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
where;
P is the power (kW)
t is time (h)
E = 1.2 kW x 0.25 h
E = 0.3 kWh
As a result, the total amount of electrical energy consumed is 0.3 kWh.

Which of the following has the highest average salinity?
w. Mediterranean Sea
x. Atlantic Ocean
y. Arctic Ocean
Z. Gulf of Mexico
Salinity is the measure of how much salt has been dissolved in a body of water. It significantly affects conductivity and has an impact on a variety of chemical properties of natural waters, as well as the biological processes that occur there.
Explain about the salinity?Lake describes the Dead Sea. The Salt Sea is another name for it. With a salinity of 33.7%, the Dead Sea is the saltiest body of water on earth.
Either grams of salt per kilogram of water or parts per thousand are used to express salinity. For instance, your salinity is 1g/kg, or 1 ppt (ppt, or ), if you have 1 gram of salt and 1,000 grams of water. Salt content in freshwater is typically less than 0.5 ppt.
The Atlantic Ocean is the saltiest of the five ocean basins. Near the equator and at both poles, salinity generally decreases noticeably, though for various reasons. The tropics, which are close to the equator, consistently get the most rain.

Enzymes_______activation energy and______up chemical reactions.
A. lower, speed
B. speed, lower
C. lower, slow
Answer:
A: lower, speed
Explanation:
Enzymes definitely speed up chemical reactions because they are proteins that act as biological catalysts. Catalysts speed up reactions without being used up themselves. They are reusable.
Lowering the activation energy makes the reaction faster because less energy is required to do the same task.
B and C do not make sense because speed activation energy doesn't make sense and slow up doesn't make sense either.

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.

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.

Living in rural environments can be difficult due to the distance from the major centers and amenities of urbanization, since the way in which the human pecies has adapted to live in a community is direct linked to technologies that are sometimes nor available in a rural region. The lack of diversity of functions can also become a hindrance, since the rural region have agricultural activities or related to agriculture as the marjor, or in some cases the only, possibility of branch of work.
To the environmental the increase in people living in a rural region is the increased comsumption and exploitation of local natural resources, as well as the urban expansion for housing construction and other infrastructures. The population growth in the region can inevitably leads to climate changes and modifications in the fauna and flora.

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.
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.

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.
