Currently, Coal is widely used because it's cheaper.
hydroelectric energy is more expensive (to build) but it has much much less waste, and no carbon emissions unlike coal
rest options are false.
Answer:
B.) Hydroelectric energy is associated with less waste production than coal.
Explanation:
While coal produces ash, CO2, CO, NOx, SOx, and many other waste products, hydroelectric energy has no waste products and doesn't pollute the environment.

what are some non examples of hydroshere
The hydrosphere is made up of all the water on the planet, including the water found below the surface and in the atmosphere. A planet's hydrosphere may be liquid, vaporous, or composed of ice. The three surface water bodies on Earth are oceans, lakes, and rivers.
What are some non examples of hydrosphere?It comprises all surface waters that are liquid or frozen, groundwater that is contained in soil or rock, and atmospheric water vapor. The hydrologic cycle continuously circulates almost all of these waters. In wells and aquifers, it can also be found underground as groundwater.
Within the hydrosphere, water circulates in a cycle. Clouds contain water that eventually falls to Earth as rain or snow.
Therefore, Rivers, lakes, and seas are where this water gathers. The cycle is then restarted by its evaporation into the atmosphere. The water cycle refers to this.

explain the gaseous exchange in lungs
Answer:
Gas exchange is the delivery of oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs. It occurs in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.

Rainsford's feelings about his host.
Rainsford's impression of the dining room.
O Rainsford's impression of the island.
Answer:
O Rainsford's impression of the dining room.
Explanation:
Richard Connell's short story "The Most Dangerous Game" revolves around the famed hunter Sanger Rainsford and his change of fortune when he was left stranded in an island famed for hunting humans as a game by the island's barbaric owner General Zaroff.
In the given excerpt, the narrator reveals the "dining room to which Ivan conducted (Rainsford)". The impression that the hall was "of feudal times with its oaken panels, its high ceiling, its vast refectory table where twoscore men could sit down to eat" reveals the outline of the enormous dining hall where Rainsford was conducted to eat with Zaroff. This narrative point of view allows the reader to experience the impression of the dining room.

What has a greater influence on protein levels?
(1 point)
Protein degradation has a greater influence because outside factors like antibiotics can
cause it, and it is difficult to recover from.
O
Protein degradation has a greater influence because they are denatured faster than the cell
can produce them.
mRNA destroyer concentration has a greater influence because it is destroying mRNA before
proteins can even be produced.
mRNA destroyer concentration has a greater influence because mRNA is destroyed right
after the proteins are produced.
Answer:
mRNA destroyer concentration has a greater influence because it is destroying mRNA before proteins can even be produced.
Explanation:
Proteins are synthesized from mRNA through the process of translation. mRNAs are first synthesized from a coding DNA template through the process of transcription. Hence, if mRNAs are destroyed, it means proteins will not be synthesized at all.
Protein not being synthesized at all means that mRNA destroyer concentration has a greater influence on protein levels than protein degradation. With protein degradation, not all the protein is degraded at once and some quantity of the protein can still be found, but with mRNA destroyer concentration, no protein can be found at all because it was not synthesized in the first place.

Tree-dwelling primates have prehensile tails for gripping branches. Tree-dwelling opossums also have prehensile tails. Many birds and some kinds of bats that feed on plant nectar all have long flexible tongues. Primates use opposable thumbs to help climb. New World monkeys also have prehensile tails, but Old World monkeys do not. Marsupial mammals throughout Australia show a wide diversity of forms that reflect the habitats in which they live. Hawaiian honeycreepers, with their elongated, nectar-sipping bills, all evolved from a finch-like ancestor.Answer and Explanation:
Tree-dwelling primates have prehensile tails for gripping branches. Considering recent ancestors, the prehensile tail trait can be considered as a convergence example that occurred among different groups. But we can also think about it as a common descent if we consider the farthest primates ancestor. Although still controversial, Plesidiapsi might be considered a common ancestor of primates, that evolved from a ree-dwelling mammal with a long tail. It is believed that this animal used to live in trees. Tree-dwelling opossums also have prehensile tails. Convergence. Many birds and some kinds of bats that feed on plant nectar all have long flexible tongues. Convergence. These are two groups that are very separated from each other, and they developed different traits according to their needs separately. Some of the species of these two groups adapted to feed on the same plant so they needed to develop the same characteristic to obtain nectar.Primates use opposable thumbs to help climb. New World monkeys also have prehensile tails, but Old World monkeys do not. Common descent . The common ancestor had a prehensile tail, some of the descendants developed the tail but some others did not.Marsupial mammals throughout Australia show a wide diversity of forms that reflect the habitats in which they live.

How are the molecules in photosynthesis and cellular respiration similar? Please include descriptions of the molecules
Answer:
They are similar because they both produce energy but in two different forms.
Photosynthesis- It produces oxygen and G3P, simple carbohydrate molecules that are high in energy and can be converted into glucose, sucrose, or other sugar molecules.
cellular respiration-During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water.
They exhibit the same responses, but they do so in reverse. Carbon dioxide and water are converted during photosynthesis into glucose and oxygen. Carbon dioxide and water are produced during respiration in exchange for glucose and oxygen.
What similarity in photosynthesis and cellular respiration?Energy transformations from one form to another are a part of both respiration and photosynthesis through a sequence of metabolic reactions.
The reactions that are carried out by both processes—which both use and produce ATP—are carried out on membranes and are managed by enzymes.
Light energy is converted by photosynthesis into chemical energy that is stored in glucose, which is then released by cellular respiration to create ATP, the life-sustaining compound.
Therefore, They are similar because they both produce energy, but in two different forms.

Shivering and vasoconstriction would be signaled to cause a: A. increase in pH. B. decrease in temperature. C. decrease in pH. D. increase in temperature.
Answer:D
Explanation: shivering occurs when someone is cold and vasoconstriction is when the blood vessels close to the skin and the veins closer to the skin surface constrict as a result of dat air doesn’t enter the body
Vasoconstriction is the narrowing of the blood vessels that hinders blood flow. Vasoconstriction and shivering will lead to an increase in the temperature through thermoregulation. Thus, option d is correct.
What is thermoregulation?Thermoregulation is the maintenance and balancing of the temperature and heat in the body. They are regulated by many factors including shivering and vasoconstriction.
During the vasoconstriction, the blood vessels close to the skin surface close and the body shivers as a result of cold or decreased temperature. This signals the body to increase the temperature so that shivering can be stopped.
Therefore, vasoconstriction and shivering signal the body to increase the temperature.
