The diagram provides an overview of how dialysis works. Using this model as an example, explain how the diyalysis machine performs the function that's normally performed by the kidneys

Answers

Wanna help but where’s the diagram?

Answer:

The main job of a kidney is to filter toxins and waste products from the blood. In dialysis, the machine takes in blood from the artery and pumps it through a semipermeable membrane. This function is similar to that of the capillaries in the kidney. They allow waste products to filter from the kidneys. The waste excretes into a bag in a manner similar to how the bladder excretes urine from the body. The clean blood pumps back into the body and is carried back to the heart via a vein.

Please help me asappp !! Now I need help :)))​

Answers

Answer:

1. Glucose And Oxygen.

2. Transpiration is the process by which water is lost in the form of water vapour by evaporation from the surface of leaves and other serial parts of plant .

3. A. Cooling Effect : The water keeps on evaporating from the leaf surface during transpiration . The heat required for evaporation of water is obtained from the plant itself and thus, the plant cools itself when it is hot outside.

B. Transpiration Pull : As water evaporates from the leaf surface, the roots pull up more water from the soil to make up for the water loss during transpiration .As a result, important mineral salts are also brought along with the water. These salts are necessary for the growth of the plant .

4. Leaf Tendrils : Sweet Pea

Spines : Cactus

Scale Leaves : Onion

5. Pitcher Plant, Venus FlyTrap, Blodderwort

6. Normally plants propogate with the help of seeds contained in the fruits . But some new plants may also be produced from other part of the plant such as the roots, stems, and leaves . This type of reproduction is called vegetative propogation .

E.g. = Bryophyllum .

Disruptive selection produces two or more species with two different traits nothing in the question says two different scorpions where formed one with big pinchers and another with big stingers no it just talks about them slowly forming big pinchers

C. Stabilizing

Stabilizing selection is when two species are produced with more similar traits nothing vastly different, I would consider them forming really big pinchers to be an extreme

An earthquake originated in New York State. The P-wave travel time for this earthquake was recorded in the data table below for four widely separated seismic stations, A, B, C, and D If the first P-wave arrived at seismic station A at 10hrs:22min:30sec, what was the origin time for the earthquake?

Answers

The provided question is incomplete as it lacks the essential information to give answer. however, the complete question is attached as image.

Answer:

The correct answer is option :  c. 10hrs: 14min: 10sec.

Explanation:

The question provides the following information to answer the question:

The P wave takes time to reach Seismic station A = 8 min:20 sec

P-wave arrived at seismic station A at : 10hrs:22min:30sec

So, the origin time of earthquake would be: 10hrs:22min:30sec - 8 min:20 sec = 10hrs: 14min: 10sec.

Thus, the correct answer is :  10hrs: 14min: 10sec.

Water conservation is an important issue for many reasons. One factor is that water conservation preserves and protects our natural resources. Conserving water means more water is available to serve additional water needs, as well as for wildlife and recreation. Water conservation practices can result in lower wastewater discharges which can mean an improvement in overall water quality. Conserving water diminishes our need to find or build new water sources, leaving them in reserve for our possible later use. Preservation does result in
A) lower algae levels
B) reduction in industry standards
C) slowing the building of new housing
D) lessening the need to find new water sources
