Answer:
I would think Channel proteins but I could be wrong
The sodium potassium pump is the only one of the options that requires the transfer of the terminal phosphate group of ATP.
Active transport is the process of moving molecules across a cell membrane against their concentration gradient. This requires energy, which is provided by ATP hydrolysis.
Aquaporins are water channels that allow water to move through the cell membrane without requiring energy. Carrier proteins and channel proteins are also involved in passive transport, which does not require energy.
The sodium potassium pump is an example of active transport. It uses the energy from ATP hydrolysis to move sodium ions out of the cell and potassium ions into the cell. This creates an electrochemical gradient, which drives the movement of other ions and molecules across the cell membrane.
The sodium potassium pump is essential for maintaining the electrical potential of the cell membrane. It is also involved in the transport of nutrients and waste products into and out of the cell.

1. Which of the following scenarios would not prompt the cell to start dividing? A. a bone elongating during puberty B. tissue healing after an injury C. stretching of a cell to allow for more fat storage
Answer:
I think the answer is C
Explanation:
The scenario that would not prompt the cell to start dividing is the stretching of a cell to allow for more fat storage.
What do you mean by Cell division?Cell division may be defined as the process by which a parent cell divides into two or more daughter cells.
The stretching of a cell to allow for more fat storage is usually done by the process of cell growth, but not by the process of cell division.
Therefore, the scenario that would not prompt the cell to start dividing is the stretching of a cell to allow for more fat storage.

How would you identify a floodplain that has not been immersed for a long time?
Answer:
Floodplains are identified as zones on FEMA Flood Insurance Rate Maps (FIRMs). Flood zones are defined by type, depth, and frequency of flooding. But the shape and nature of a floodplain may also change over time as the main channel of a river naturally migrates through erosion and accretion, impacting how and where excess water may first over top the banks of the river during a flood event. Geologically ancient floodplains are often represented in the landscape by fluvial terraces. These are old floodplains that remain relatively high above the present floodplain and indicate former courses of a stream. I HOPE THIS HELPS YOU :)
Explanation:
The geology of a floodplain the natural development of floodplains is primarily influenced by two processes: aggradation and erosion which help to identify that it has not been immersed for a long time.
What do we should know about floodplain ?
The flood fringe extends beyond the floodway. From the floodway's outer banks to a river valley's bluff lines, the flood fringe extends. The point at which the valley floor begins to rise into bluffs is marked by bluff lines, which are also known as valley walls.A generally flat area of land adjacent to a river or stream is known as a floodplain. It extends from the riverbanks to the valley's outermost edges. There are two components to a floodplain. The floodway, which is the river's primary channel, is the first. The channel may be dry for a portion of the year in floodways, which can sometimes be seasonal.The process by which earth is worn away by the movement of a floodway is referred to as the erosion of a floodplain. The term "aggradation" of a floodplain refers to the process by which earthen material expands as sediment is deposited by the floodway. A floodplain is eroded by a river as it meanders or curves.Floodplains are frequently made up of features like oxbow lakes and seasonal wetlands. These features are the result of erosion and deposition.A floodplain's erosion and aggradation, or accumulation of land elevation, may be exacerbated by a meandering stream. A river that is wide, shallow, and braided is a typical aggradation environment. River deltas, where the main floodway is divided into discrete channels and tiny islands, are frequently found in braided rivers.To know more about floodplains check this:

A student observes a cell under a microscope. She sees a cell wall and a nucleus. What type of cell is she observing?
O eukaryotic animal cell
O eukaryotic plant cell
O prokaryotic cell
O bacterial cell
Answer:
eukaryotic plant cell
hope this helps
Only eukaryotic plant cells have a cell wall and a nucleus. Option 2 is correct.
Eukaryotic cells are cells that have a nucleus and other membrane-bound organelles. Prokaryotic cells do not have a nucleus or other membrane-bound organelles.
Plant cells are eukaryotic cells that have a cell wall. The cell wall is a rigid structure that surrounds the cell membrane. It provides support and protection for the cell. Animal cells do not have a cell wall.
The nucleus is the control center of the cell. It contains the DNA, which is the genetic material of the cell. The nucleus also contains proteins that control the activities of the cell.
So, if a student observes a cell under a microscope and sees a cell wall and a nucleus, she is observing a eukaryotic plant cell.

How Enzymes Function Enzymes are biological catalysts. They can increase the rate of chemical reactions as much as a millionfold by lowering the energy barrier of a reaction.
Part A - Enzymes and activation energy The graph presents three activation energy profiles for a chemical reaction (the hydrolysis of sucrose): an uncatalyzed reaction, and the same reaction catalyzed by two different enzymes. Rank these by reaction rate, as measured by the rate of product formation (from the most product formed to the least product formed). To rank items as equivalent, overlap them.
Part B - Factors that affect enzymes Complete this vocabulary exercise relating to enzymes. Match the words in the left-hand column to the appropriate blank in the sentences in the right-hand column. HelpReset cofactor specific denatured substrate active site catalyst complex
1. An enzyme is when it loses its native conformation and its biological activity.
2. An enzyme is considered a because it speeds up chemical reactions without being used up.
3. An enzyme is considered because of its ability to recognize the shape of a particular molecule.
4. A , such as a vitamin, binds to an enzyme and plays a role in catalysis.
5. When properly aligned, the enzyme and substrate form an enzyme-substrate (ES) .
6. A substrate binds to an enzyme at the , where the reaction occurs.
7. In a catalyzed reaction a reactant is often called a _________.
Answer:1. An enzyme is denatured when it looses its native conformation and its biological activity. Enzyme is a protein and at high temperatures, the shape of the proteins is altered, preventing it from its function. In addition change in pH above optimal may also cause denaturation of enzymes inactive.
2. An enzyme is considered a catalyst because it speeds up chemical reaction without being used up. A catalyst is a substance that speeds up chemical reactions by reducing the activation energy of the reactants, they are not consumed during the reactions. Enzyme are biochemical catalysts that speeds up chemical enzymatic reactions without being consumed just like normal catalysts.
3. An enzyme is considered specific because of its ability to recognize the shape of a particular molecule. One property of enzyme is that they are substrate specific and will act on specific substrate, others will act on a specific type of chemical bond or functional group, while others will catalyze only one reaction (absolute specificity)
4. A cofactor such as a vitamin, binds to an enzyme and plays a role in catalysis. Cofactors are mostly metal ions (such as Zn ions or iron ions) or coenzymes are inorganic and organic chemical that aid the activity of enzymes. Coenzymes are non protein molecules mostly vitamins or vitamins derivatives that enhance enzyme activity.
5. When properly aligned, the enzyme and substrate form an enzyme-substrate (ES) complex. Es complex is the intermediate formed when a substrate molecule interacts with the active sites of an enzyme. After the formation of the complex then the substrate undergoes a chemical reaction and is converted to product.
6. A substrate binds to an enzyme at the active-site, where the reactions occurs. Active sites is a region on the enzyme where substrate molecules bind and undergoes a chemical reaction where it is converted to product. These sites contain the binding site and the catalytic site.
7. In catalyzed reaction, a reactant is often called a substrate. Substrate molecule is the substance that is acted upon by an enzyme and is converted to a product. The substrate forms an interaction with the binding site of the active site then the catalytic site of the active site converts the substrate to a product during catalysis.
1. Denatured
2. Catalyst
3. Specific
4. Cofactor
5. Complex
6. Active Site
7. Substrate
The induced fit model states an substrate binds to an active site and both change shape slightly, creating an ideal fit for catalysis. When an enzyme binds its substrate it forms an enzyme-substrate complex. ... The enzyme will always return to its original state at the completion of the reaction.
"The active site of the enzyme has a complementary rigid structure" belongs to the key and lock system

What term is used to describe the state at which a solute moves down its concentration gradient
through the plasma membrane and becomes evenly distributed in the cytosol?
Diffusion is used to describe the condition at which a solute moves down its concentration gradient through the plasma membrane and becomes uniformly distributed in the cytosol.
What is Diffusion?Diffusion is the type of net movement of particles from an area of higher concentration to an area of lower concentration. It is driven by the gradient in Gibbs free energy or chemical potential.
This occurs through the semi-permeable membrane like the plasma membrane. Diffusion of small molecules and macromolecules such as proteins in aqueous solutions plays an important role in microorganisms, plants and animals.
Few examples of Diffusion are:
Perfume is sprayed in one part of the room so that it can spread easily so that we can feel its smell everywhere. A drop of food coloring spread throughout the water in a glass, the whole glass will be colored.Thus, Diffusion is used to describe the condition at which a solute moves down its concentration gradient through the plasma membrane and becomes uniformly distributed in the cytosol.
