The angle subtended by stars in the night sky is orders of magnitude smaller than the acuity threshold you calculated in 1). Why are we able to see objects that are much smaller than the angle subtended by the gap in the acuity threshold experiment? (50 word max)

Answers

Answer 1

Answer is given below

Explanation:

we consider here gap in character size is 0.75 mm

and distance is 300 mm

so minutes of arc is = 0.85944

and

visual acuity is express as

V = standard view distance D ÷ distance at which each letter D' ................1

There is visual acuity under the eyes, on which the object cannot be determined Factor factor mainly determines refractive error and contrast angle brightness or brightness and duration of contrast and exposure The target resolution threshold is expressed as a small angle, which can reduce the distinction between important elements of the stimulus pattern such as a pair of dots. Relaxation is specified in terms of its angular size

If a solution is undergoing a reaction where CO2 is being created a product, what color is the phenol red-containing solution shifting toward?

Answers

Answer:

YELLOW

Explanation:

Phenol red is a biological indicator used to monitor changes in pH. The phenol red indicator changes color ranging from yellow to pink with respect to changes in pH. In an acidic pH i.e. <7, the phenol red changes to a YELLOW color while in an alkaline pH i.e. >7, the phenol red changes to a PINK pH.

The presence of carbon dioxide (CO2) increases the hydrogen ion concentration (H+) of a solution (lowering its pH or making it acidic).

Therefore, in a reaction where CO2 is created as a product, it means the CO2 content of that solution increases. Hence, the phenol red solution will be shifting towards the YELLOW color in response to a decreasee in pH (acidic).

If a solution is undergoing a reaction where CO2 is being created a product, the phenol red-containing solution will be shifting toward the yellow color.

An indicator is an organic dye that changes its color as the pH of the solution changes. An indicator has a different color in acid, base and neutral media.

Phenol red has a yellow color in acidic medium and red color in a basic medium.

Since the production of CO2 lowers the pH of the system, the color of the solution shifts towards yellow.

A.) adhesion
B.) cohesion
C.) surface tension
D.)Universal Solvent

Answers

Answer:

D

Explanation:

The property of water that helps it to dissolve sugar is the universal solvent property.

Water has the inherent attribute to dissolve a wide variety of substances due to the arrangement of the atoms that make up water molecules. The molecules of water are made up of hydrogen and oxygen, with the latter being negatively charged while the former is positively charged.

The polar arrangement gives water the capacity to be able to dissociate ionic substances into their respective positive and negative ions and also allow water to dissolve more substances than any other solvent in the world.

Which motion of particles across a membrane requires energy?
O from high concentration to low concentration
from low concentration to high concentration
with no concentration gradient
O through dynamic equilibrium

Answers

Answer:

B. From low concentration to high concentration

Explanation:

I got it right on edge :)

Answer:

B

Explanation:

You can think of it as a very useless sponge and water.

If you have a dry sponge you can consider this an area of low concentration, and the bucket of water as an area of high concentration of water.

It is easy to soak up water with a dry sponge with osmosis when the high concentration easily fills the low concentration sponge.

On the other hand, a soaked sponge will have a great time trying to soak up a bucket of water with an already wet sponge.

This is a crude example of differing high to low or low to high concentration.

Osmosis is limited to water particles, whereas diffusion is basically molecules.

 

Osmosis is the movement of water along the concentration gradient.

Active transport is the use of energy to move particles against the concentration gradient so it is active, it is attempting to enact homeostasis.

Passive transport is the movement of particles by diffusion without energy so it is just passive, not aggressive.

Diffusion is the movement of particles along the concentration gradient.

For certain medical procedures, body parts (such as organs and tissues) may require transportation over great distances. Certain procedures must be followed in order for the body parts to remain usable for the patient. During a pancreatic transfer, specialists have to be mindful of trypsin (an enzyme located in the pancreas). If the trypsin is functioning normally during such transfers, early decay of the pancreas will occur. If the pancreas decays, the transplant will be unsuccessful. Examine the graph below. Which of the following procedures would be necessary for a team of clinical specialists to follow in order to ensure a successful transplant?

Answers

Answer:

Hello. You did not add the necessary graphics for this question to be answered. However, I can help you by showing that one of the procedures that a medical team can do to inhibit the action of trypsin in the deorization of the pancreas is the use of ulinastine.

Explanation:

During the process of isolating a pancreas to be transported, the use of ulinastine is shown to be efficient for inhibiting trypsin, which promotes deterioration of the pancreas. Unilastine is also an anti-inflammatory, which will bring even more benefits with its use.

Thus, with the use of a ulinastine solution, the pancreas has more time to reach the transplant site and promote successful surgery.

Answers

Answer:

Hydrocortisone inhibits vascular leak due to proinflammatory mediators.

Explanation:

Hydrocortisone is a corticosteroid anti-inflammatory medication capable of reducing the body's immune response, and thus reduce pain and itching. Hydrocortisone treatment is used in different health problems, including, among others, piles and itchy bottom, mouth ulcers, skin problems, adrenal insufficiency, etc. This drug is also utilized in persons that don't produce enough cortisol, a natural stress hormone. It has been shown that hydrocortisone may lead to enhancement of vascular leak, which suggests secondary effects on myocardial and endothelial cells.

Hydrocortisone inhibits vascular leak due to proinflammatory mediators.

Hydrocortisone is a corticosteroid anti-inflammatory medication that relieves pain and itching by decreasing the body's immunological reaction. It is used to treat piles and itchy bottoms, mouth ulcers, skin diseases, adrenal insufficiency, and other conditions. People who don't produce enough stress hormones may benefit from this medicine.

B. Different blood types have different antigens that will be attacked by someone with antibodies against that blood type.
C. They need to have the same blood type because their DNA must be similar enough to blend or will cause side-effects and possibly be rejected.
D. Your blood type doesn't matter as long as you get the correct amount of blood in a transfusion.

Answers

Answer:

A and B

Explanation:

Doctors need to check the blood type of a person before administering blood transfusion because different blood types have different antibodies that will be attacked by someone with antigens against that blood type.

The blood that would be given to a person must match the blood of that person in terms of the type of antigens. If the blood antigens are different, the antigens present in the blood of the individual undergoing blood transfusion would consider the antigens present in the blood being received as an enemy and attack it. This will lead to agglutination of the blood in the system of the person, a process that often leads to death.

Hence, O-positive individuals must always receive O-positive blood while O-negative individuals must always receive O-negative blood.
