Cellulose is a polysaccharide (carbohydrate) and is a basic structural
component that makes up plant cell walls. Decomposers, such as bacteria and
fungi, produce cellulase to quickly break down cellulose. Cellulase is a(n)
hansport protein
Struttura Proton
Hormone
Enzyme
Answer:
Enzymes
Explanation:
A family of hydrolytic enzymes known as cellulases is responsible for the cellulolysis or hydrolysis of the polysaccharide cellulose, which results in the formation of monosaccharides such as glucose and shorter polysaccharides and oligosaccharides. Because of their numerous applications, these enzymes have a significant economic impact on the world.
What does the graph tell you about the concentration of salt inside the cell?
Answer:
So,
Assuming that the plasma membrane is either semipermeable or fully permeable, either diffusion or osmosis will even out the concentration eventually. Therefore, options A and B are eliminated.
The only options left both say that osmosis will take place. We know that osmosis will always move the solvent from an area of low solute concentration (outside the cell) to an area of high solute concentration (inside the cell). Thus, water will move into the cell through osmosis. That is option C.
If the cell cannot get rid of the water quickly enough, the cell will explode by cytolysis.

Fracking uses highly pressurized fluids, such as water mixed with sand and chemicals, to drive open cracks that exist in underground rock. Which statement
best describes an environmental consequence of this process for ecosystems?
O Wastewater is contaminated with oil and becomes sludge in landfills
O Water vapor is released into the air, which is considered a greenhouse gas,
Heavy metals are released into surrounding soil, poisoning local vegetation
O Billions of gallons of water are pulled from surrounding areas
The correct answer is that chemicals added to the liquid can contaminate groundwater.
Fracking is a method of drilling fossil energy resources, which requires a lot of water and consumes local water resources. It is pumped with high pressure water, sand and chemicals, causing high pressure to block the porous rock and release gas.
The water spill itself destroys nature from the drilling site, and may even cause earthquakes, especially due to the pumping of abundant wastewater into porous rock types such as limestone. For example, Oklahoma appears to have become a special earthquake risk area. The biggest impact of water distortion is on groundwater. In Wyoming, USA, the same chemicals found in groundwater have been found in groundwater, and some of them are toxic or carcinogenic.

As wind passes over a mountain, the side over which the wind rises tends to be ____________________ and the side that experiences the downward movement of air tends to be ____________________.
drier; moist and rainy
moist and rainy; drier
rainforest; desert
desert; rainforest
Given what we know about the effects of air currents on mountain ranges we can confirm that the correct option is option B, moist and rainy on one side while being dier on the other.
Mountains are described as having two sides in regards to their relationship with the air currents. The side of the mountain on which the wind rises is known as the windward side, whilst the side on which air descends is known as the leeward side. The windward side is typically in contact with warmer, moist air from the ocean and other bodies of water.
When coming in contact with the mountain, the air is forced to rise and begins to cool, which often leads to rain or snow. The leeward side of the mountain receives the air that has now already lost the majority of its moisture with its pass through the windward side of the mountain. This air also tends to become warmer as it descends, which explains the dry nature of the leeward side of mountains.

They are not uniform in form and function.
Explanation:
leukocytes are white blood cells. mainly 4 killing bacterial infections.
Leukocytes are the specialized cells which are a part of blood. These are known as white blood cells. These protects the body. These produce antibodies. Thus, the correct options are B, D, and E.
What are Leukocytes?
Leukocytes are the white blood cells. These are a type of specialized cell type which is present in blood along with erythrocyte and plasma. Leukocytes are primarily responsible for protecting the body from pathogens and germs by producing antibody proteins which fight against these organisms.
Leukocytes are irregular in shape. They can change their shape to engulf or kill the bacteria which enters the blood to prevent disease. Erythrocytes change their shape which allows them to pass through the capillaries which are very tiny.
Therefore, the correct option is B, D, and E.

Examine the comparison between a eukaryotic cell and a prokaryotic cell. Which two lettered choices provide a comparison of structures that encode genetic information for the cells? A) A and D B) B and D C) C and D D) None of these choices, as prokaryotic cells do not contain DNA
I am almost certain it is A) a and d) but I need reassurance.
Answer: c & d
Explanation:
C and D provide a comparison of structures that encode genetic information for the cells. So, the correct option is C.
What are Prokaryotic and Eukaryotic cells?Prokaryotic cells are single-celled microorganisms known to be the earliest on earth. Prokaryotes include Bacteria and Archaea. The photosynthetic prokaryotes include cyanobacteria that perform photosynthesis. A prokaryotic cell consists of a single membrane and therefore, all the reactions occur within the cytoplasm which can be free-living or parasites.
Eukaryotic cells are defined as having a nucleus enclosed within a nuclear membrane and form large and complex organelles. Protozoa, fungi, plants and animals all contain eukaryotic cells which are classified under the kingdom Eukaryota.
Thus, C and D provide a comparison of structures that encode genetic information for the cells. So, the correct option is C.

Fill in the blank with the correct term to complete the sentence provided. When the valve between the right atrium and right ventricle has an abnormal narrowing, this is known as
(Answer is NOT pulmonary valve or pulmonary stenosis)
Explanation:
if its correct please let me know
A narrowing of the valve between the lung arteries and the lower right heart chamber (right ventricle) is known as pulmonary valve stenosis (pulmonary arteries).
What is an abnormal narrowing in the heart?The valve flaps (cusps) of a constricted heart valve may thicken or stiffen, as a result, the valve's blood flow is decreased.
When that valve narrows, blood cannot flow correctly and aortic stenosis develops, mild to severe cases of the illness are possible.
The left ventricle of your heart has to work harder over time to force blood past the stenotic aortic valve.
Therefore, an abnormal narrowing of the right atrium and right ventricle is due to pulmonary valve stenosis.

Having hair is a(n) _________ trait among mammals.
Answer:
Derived trait
Explanation:
An ancestral (or primitive) trait/character is a feature inherited from the common ancestor of the species/group of interest, while derived traits are those that were absent in the last common ancestor of the group of interest. For example, considering mammals as the target group, the presence of hair is a shared derived trait relative to other vertebrates, i.e., amphibians, reptiles, and birds. However, this trait (hair) is ancestral for humans since the genetically closest species to humans (e.g., chimpanzees) also have hair.
