Answer:

23a: The priest and the levite

23b: (from wikipedia) "In Jewish culture, contact with a dead body was understood to be defiling. Priests were particularly enjoined to avoid uncleanness. The priest and Levite may therefore have assumed that the fallen traveler was dead and avoided him to keep themselves ritually clean."

23c: He took care of himand helped the wounded traveler to recover.

You observe a high proportion of malarial infections in a small village located in Angola. Malaria is caused by the protozoan Pl

svet-max [94.6K]

Answer:

B and C.

Explanation:

The epidemiological triangle is an illustration of interaction among suitable hosts, disease agents, and the environment that drives successful outbreak of diseases.

In order to successfully tackle or reduce the incidence of a disease, the triangle has to be broken.

In the case of malaria which is caused by plasmodium but spread through the female anopheles mosquito, one way of breaking the epidemiological triangle is to eliminate female anopheles mosquito in the environment using any possible means. This will stop the spread of the parasite and hence, the disease.

Another way to reduce/prevent malaria is to prevent the vector, female anopheles mosquito from getting to the host, the human populace. This can also be achieved by several possible means.

Relocating the entire village to a neighbouring village might not break the epidemiological triangle as long as female anopheles mosquito still abounds. In the same vein, antibacterial drugs will not help to treat malaria. However, instructing residents on personal protective measures and controlling the vector through chemical larvicides will go a long way in breaking the triangle and reducing the incidence on the malaria disease.

The correct options is B and C.

Consider the following geometric solids a sphere with a ratio of surface area to volume equal to 0.08 M negative one a right cir

azamat

Options:

A. The rate of diffusion would be the same for the two models.

B. The rate of diffusion would be faster for the right cylinder.

C. The rate of diffusion would be slower for the right cylinder.

D. The rate of diffusion would be faster for the sphere.

Answers:

The rate of diffusion would be faster for the right cylinder. Thus, the correct option is B.

To begin with, we must comprehend how the ratio of surface area to volume affects the rate of diffusion.

When comparing the ratio of surface area to volume, a body with a larger surface area will have a higher rate of diffusion than a body with a smaller surface area. It can be expressed mathematically as:

V∝ R (whereas v is the diffusion rate and r is the surface area to volume ratio)

The answer to the question's surface area to volume ratio for spheres is given 0.8m⁻1

For a right circular cylinder, the surface area to volume ratio is provided is 2.1 M.

The right circular cylinder has a larger ratio, hence it is obvious that the right circular cylinder will have a higher rate of diffusion because the rate of diffusion is directly related to the surface area to volume ratio.

What are the two factors that affect the friction between two surfaces

BabaBlast [244]

Answer:

The two factors are:

• The kind/type of surface involved.

• The force that the surface are being pushed together.

Explanation:

Friction can be said to be the general term used to describe the force that one surface exert on another when they rub against each other.

When the surface is partially not smooth or totally rough, a greater force is been needed to move one surface past the other.

The weight of the can also significantly be a key factor. This is where the need to friction reduction come to play a role; and need for friction reducers like lubricant, rollers etc helps.

where the carbon atoms of acetyl coa end up and where the energy that was stored in acetyl coa ends up. krebs cycle

ruslelena [56]

Since each glucose molecule produces two acetyl-CoA molecules, the Krebs cycle must be completed twice to produce the four CO2, six NADH, two FADH2, and two ATPs.

Catabolic reactions occur within cells during cellular respiration. It is a biochemical process by which waste materials are removed and nutrients are broken down to generate energy, which is then stored in the form of ATP. The process of aerobic respiration needs oxygen.
The Krebs cycle, also known as the citric acid cycle, is the last step of oxidation for amino acids, lipids, and glucose.
Other than glucose, many animals rely on other substances for energy.
Protein's metabolic byproduct, amino acids, are deaminated and converted to pyruvate and other Krebs cycle intermediates.
They begin the cycle and are broken down, for example. On deamination, alanine turns into pyruvate, glutamate into -ketoglutarate, and aspartate into oxaloacetate.
Acetyl CoA is created when fatty acids are -oxidized and enters the Krebs cycle. It is the primary mechanism through which cells produce ATP. Complete nutrient oxidation results in the production of a significant amount of energy.

Marine Populations Lab Report Instructions: In the Marine Populations Lab, you helped gather data to evaluate Sebastian's Snorke

stealth61 [152]

Answer:

The procedure is given below.

Explanation:

First we record the data of the pollutants that is releasing from the factory. Record the population of the coral reef which are not affected from these pollutants then take the data again and record the population of coral reef that is affected from the pollutants. If the population of coral reef that is affected from that pollutants increases it means that the pollutants damaged the coral reef population at higher rate. The purpose of this lab is to find out the negative effects of pollutants that is released from the factory on coral reef.
