Did the enzymes from Claire’s small intestine breaks down the protein at a low, normal or high rate?
Answer: low rate
Explanation:
Claire is a Great Dane who was losing weight despite the fact that she is eating. Claire doesn't have an increase in appetite and also doesn't have enough energy that is required for her to play.
Claire is losing weight because food the enzymes in her body doesn't break down the food that she eats. When compared to a dog that was healthy, the enzymes from Claire's small intestine broke down protein at a low rate.:

what can the enzyme sucrase break down?
Answer:
Sucrase is an enzyme that breaks sucrose down into glucose and fructose.
Explanation:
The bonds between the glucose and fructose molecules making up the disaccharide sucrose break due to the enzyme sucrase, and water is added as
H
and
OH
to the two molecules. This is called a hydrolysis reaction.
Hydrolysis is a chemical reaction in which water (hydro) breaks (lysis) a chemical bond in a dimer (two molecules bonded) and polymer (many molecules bonded) by adding
H
to one molecule and
OH
to the other molecule.

Answer:
its osmosis
Explanation:
Active transport is the energy consuming process that involves the movt of molecules from their region of low concentration to a region of high concentration.
Diffusion is the net movt of molecules or ions from a region of their higher concentration to a region of their lower concentration.
Facilitated diffusion is the transport of molecules and ions across a membrane by specific transport proteins,carriers and channel proteins found within the membrane in the direction of lower concentration down a concentration gradient.
Osmosis is the net movement of water molecules from a region of their high concentration to the region of their lower concentration through a partially permeable membrane. OR this is the passive movement of water molecules across a partially permeable membrane from a region of lower solute concentration to a region of higher solute concentration.

Scientists also believe that dark matter is not composed of antimatter. If it were, they would be able to detect this through the emission of gamma rays.

The formula for the volume V of a cylinder is V = πr2h where r is the radius of the base and h is the height of the cylinder. Solve the formula for h. Then find the height of a cylinder with a volume of 36πcm3 and a base with a radius of 3 cm. Please help me its due today
Answer:
h = 4 cm
Explanation:
First, we solve for h.
h=[tex]\frac{V}{pi*r^2}[/tex]
h = unknown
v = 36*pi
r = 3 so r^2 = 9
[tex]\frac{36*pi}{pi*9} = 36/9 = 4[/tex]

Components in the blood that affect viscosity are formed
elements, plasma proteins, WBCs, RBCs,platelets.What's viscosity provides an explanation for?Viscosity is the resistance of a fluid (liquid or gas) to trade in shape, or motion of neighboring portions relative to each other. Viscosity denotes competition to waft. The reciprocal of the viscosity is called the fluidity, a degree of the benefit of waft. Molasses, for instance, has an extra viscosity than water.
What's an IT unit?Viscosity is a measure of a fluid's resistance to glide. The SI unit of viscosity is poiseiulle (PI). Its different gadgets are newton-2nd per square meter (N s m-2) or pascal-2nd (Pa s.).

Scientists studied the evolution of horses. They concluded that horses evolved with the emergence of grasslands and an increase of predators. The digits of their early Eocene ancestor evolved into hooves. The diet changed from foliage to grasses. The molar teeth developed and became stronger. Which statements are supported by this evidence?
A) Molars became bigger to fit into the jaw structure of modern horses.
B) The molars of the horses underwent changes so they could chew meat.
C) The digits were modified to enable the horses to graze better on hard, rocky surfaces.
D) The emergence of grasslands over time led to the development of strong molar teeth in horses.
E) The digits of the horses’ feet underwent modifications, enabling them to run faster from predators.

A. Identify what parameters are not within normal ranges.
Answer:
A normal range is the restricted set of values that is optimally healthful and stable.
A reference range is usually defined as the set of values 95 percent of the normal population falls within (that is, 95% prediction interval). It is determined by collecting data from vast numbers of laboratory tests.

There are basically three major classes of membrane lipid molecules, which are: phospholipids, cholesterol, and glycolipids.
What is cellular membrane?The cell membrane, also known as the plasma membrane, is found in all cells and serves to separate the cell's interior from the outside environment.
The cell membrane is made up of a semipermeable lipid bilayer. The cell membrane controls the transport of materials into and out of the cell.
Lipids (phospholipids and cholesterol), proteins, and carbohydrate groups attached to some of the lipids and proteins are the primary components of the plasma membrane.
Membrane lipid molecules are classified into three types: phospholipids, cholesterol, and glycolipids.
Glycerol is a three-carbon molecule that serves as the membrane lipids' backbone.
Thus, these are the three molecular components of cell membranes.

AP Science Practice Question
A particular enzyme has an optimal temperature of 37°C and begins to denature at 45°C. During
denaturation, entropy increases (the protein loses much of its organization). The protein also
increases its energy content (energy must be absorbed from the surroundings to break the
numerous weak bonds that reinforce the native conformation). Thus, for denaturation, AS and
AH are both positive. Using the free-energy equation (AG = AH - TAS), explain why
denaturation becomes spontaneous at a certain temperature.
Denaturation becomes spontaneous at a particular temperature when TΔS > ΔH therefore ΔG becomes negative.
An enzyme is a biological catalyst that promotes various reactions in the body. Enzymes are proteins. There is an optimum temperature within which proteins functions effectively. Beyond this limit, the ability of the protein to function effectively is greatly hampered.
The free energy equation is ΔG = ΔH - TΔS. Since the energy absorbed increases, the entropy increases and the temperature increases, it follows that a point comes when TΔS > ΔH therefore ΔG becomes negative and denaturation becomes spontaneous at a certain temperature.

The negative membrane potential in a resting neuron is primarily due to :___________
a. high levels of chloride ions in the cell. diffusion of potassium out of the cell.
b. a higher permeability of the membrane for potassium compared to sodium.
c. both diffusion of potassium out of the cell and a higher permeability of the membrane for potassium compared to sodium are correct.
Answer:
c
Explanation:
When the membrane of the neuron is in a state of rest, the interior of the cell has a more negative charge in relation to the exterior, therefore option "c" is correct.
What is the membrane potential in a resting neuron?It is a phenomenon that occurs when the nerve cell membrane is not altered by action potentials.
Characteristics of a resting neuronThe resting potential is determined by the concentration gradients of the ions, both inside and outside the neuron, and by the permeability of the membrane.When a cell is at rest, the potassium channels are open, the potassium will tend to flow outwards (K ions), they are positive charges, therefore the cell interior will be negative with respect to the cell exterior.Therefore, we can conclude that the resting potential of a membrane occurs when they are not transmitting signals.
