What effect does viscosity have on blood flow?

A.) Low blood viscosity leads to slower blood flow.

B.) High blood viscosity leads to slower blood flow.

C.) Low blood viscosity increases resistance and leads to fast blood flow.

D.) High blood viscosity decreases resistance and leads to fast blood flow.

Answers

Answer:

B

Explanation:

High blood viscosity leads to slower blood flow. Therefore, option B is correct.

What is viscosity?

Viscosity is a measure of a fluid's resistance to flow. It describes the internal friction between different layers of fluid as they move relative to one another. In general, fluids with high viscosity flow more slowly than fluids with low viscosity.

Viscosity can affect blood flow by altering the resistance to blood flow in blood vessels. Blood viscosity is influenced by the thickness and stickiness of blood, which is determined by the concentration of various proteins and cells in the blood.

When blood viscosity is high, the blood is thicker and flows more slowly, which can increase the resistance to blood flow in blood vessels. Therefore, option B is correct.

What are the importances of Dissacharides

Answers

Answer:

Dissacharides are very important for many things in the body. They provide fuel for the cells, which ultimately determine our quality of life since their fuel regulates blood glucose levels, erythrocyte membrane stability, erythrocyte osmotic fragility and immunological competence.

An increase in lipid oxidation is seen when glucose intake is increased through high dissacharide consumption and may be helpful to individuals with non-insulin dependent diabetes mellitus (NIDDM) type 2D who have lipid disorders such as hyperlipidemia that use dissacharide consumption change lipid levels and decrease their chances of developing atherosclerosis.

Explanation:

If you were to hike up Mount Kilimanjaro in Tanzania, you would pass through several habitats, including savanna at the base, forest on the slopes, and alpine tundra near the top. Explain how such diverse habitats can be found at one location near the equator.

Answers

Given our knowledge of ecosystems, we can confirm that the diverse habitats found at one location near the equator are due to the changes in elevation.

The effects that elevation has on the climate are what enable the diversity of habitats on a single mountain. As elevation increases, atmospheric pressure decreases. This decrease in pressure then causes a decrease in temperature.

The base of the mountain is a dry and hot habitat, while as we travel upwards towards higher elevation we see a transition in habitats into a more tropical forest style and then eventually an alpine tundra, further proving the claim that elevation lowers the temperature.

Answers

The statement 'wastes will build up in vital organs, and the organism will experience disease' describes the overall consequence of proteins containing mutations. Defective proteins contain mutations.

A mutation is any alteration in the nucleotide (DNA) sequence of the genome of an organism.

A non-silent mutation can produce a change in the amino acids encoded by the nucleotide gene sequence, thereby modifying the tridimensional (3D) structure of the resulting protein.

In consequence, mutated proteins may be defective and accumulate as waste in a given organ/cell where they are expressed to perform specific functions.

Answers

Answer:this would also stop gas exchange and further limit photosynthesis

Explanation: did this on USA test prep and got it right

This would also stop gas exchange and further limit photosynthesis. Therefore, option B is correct.

What is the mechanism of opening and closing of stomata?

The content of cell sap is reduced as a result of the conversion of the organic acids into starch. This causes water to exit hard cells, and a decline in their turgor causes the stomata to close. Stomata therefore open throughout the day and close at night.

The pH of the guard cells controls stomatal opening, according to the starch sugar interconversion theory of stomatal opening. In neutral or alkaline pH, stomata open. When the guard cells are open during the day and closed at night, they contain starch during the day.

Under dehydration circumstances in the winter, stomata may close to reduce water loss for the tree. This would also stop gas exchange and further limit photosynthesis. Therefore, option B is correct.

A failure of the cell to break down which cyclin would most directly lead to increased cell division?


A) Cyclin A

B) Cyclin B

D) Cyclin E




The answer is: M-phase cyclins form M-CDK complexes and drive the cell's entry into mitosis; G1 cyclins form G1-CDK complexes and guide the cell's progress through the G1 phase; and so on. ... Specific enzymes break down cyclins at defined times in the cell cycle. When cyclin levels decrease, the corresponding CDKs become inactive.

The inability of the cell to break down cyclin D would most directly lead to increased cell division.

What is cell division?

Cell division is the process by which cells in the body divide their content and duplication of the chromosomes to produce new daughter cells.

The correct option is B.

Alpha gamma coactivation is critical for maintaining the appropriate tension on the spindle organ during contraction of extrafusal fiber.

Alpha‐gamma coactivation is a process that the muscle use to keep or maintains it's length. It works in a way that when the muscle contracts or relaxes , the sensory neuron send the information to the central nervous system about what happen to the muscle. This lead the intrafusal and extrafusal fibers to contract.

Alpha-gamma coactivation enhance the muscle spindles ensure its sensitivity to stretch the muscle lengths.

Which states of matter have a set volume? Explain why this is, based on the animations you observed for the different states of matter.
The boiling point is the temperature at which a liquid substance will turn to vapor, and also the temperature at which vapor will condense to a liquid. The boiling point of ethanol is about 80°C, and the boiling point of water is about 100°C.
What can you conclude about the intermolecular forces in water and ethanol?
Do you predict water freezes at a higher temperature or at a lower temperature than ethanol?
Recall how different Van der Waals attractions and how ionic charges changed the movement of atoms in the animation. Do you think that Van der Waals attractions or ionic charges are stronger? Why?
1. solid, liquid and gas
2.Solid can move but gas and liquid is more flexible than solid. Solid has a fixed volume while liquid and gas takes the volume of its container. Solid stays in one place while gas and liquid is flexible.
3.Among the 3 state, solid has a fixed volume while liquid takes the volume of its container. When gas is compressed, it takes the volume of its container likewise.

Answers

the answer is solid, liquid and gas

Answer:

1. Liquid, Solid, Gas

2. Solid has a set shape. Solid can move but gas and liquid is more flexible than solid.

3. Solid has a fixed volume while liquid and gas takes the volume of its container. Solid stays in one place while gas and liquid are flexible.

4. A. The stronger the intermolecular forces in a liquid the higher the boiling point. Therefore, water has a stronger intermolecular force than ethanol.

B. Water molecules are more attracted to each other than ethanol (alcohol) molecules, because water has more hydrogen atoms bonded to oxygen. ... So, that's why alcohol has a much lower freezing point

5. Ionic charges are stronger.

Covalent bonds are known to have the strongest and most stable bonds since they go deep and into the inter-molecular state. A diamond is an example of a compound with this characteristic bond.

Ionic bonds are the next strongest molecular bond following covalent bonds. This is due to the protons and electrons causing an electro-static force which results to the strong bonds. An example would be Sodium Chloride (NaCl), which when separated is Na⁺ and Cl⁻.

Van der Waals forces, also known as Dispersion forces, are the weakest type of molecular bonds. They are only formed through residual molecular attractions when molecules pass by each other. It doesn't even last long due to the uneven electron dispersion. It can be made stronger by adding more electrons in the molecule. This kind of molecular bonds appear in non-polar molecules such as carbon dioxide.
