PLEASE HURRY The Red Dots Represent Oxygen Molecules In This Diagram. This Diagram Shows __________.facilitation

Answers

Answer 1

The correct answer is option B.

Diffusion is the process of movement of both the solute and solvent. the characteristic of diffusion is that it does not require a membrane or a layer separating two parts. In diffusion particles or solutes move from a region of higher concentration to a region of lower concentration.

In the example, we can see that red particles are together in a place and after some time they get distributed evenly in the entire liquid. This process is known as diffusion as it does not require a membrane.

Answers

Hii :)

The answer is: They are rich in organic matter.

Why are they rich in organic matter?

This is  because humus is made out of dead plants, fruits, and sometimes even animal waste. Which is all good for growing plants.

This is the only answer because the rest are wrong.

For the first page: These adaptations are advantageous. For example, the dart frog’s bright colors warns predators to stay away from them. This will help them survive because they will not be bothered by any predators. Because the Hosta lives in such a crowded environment it is to its advantage that it has big leaves to get as much sunlight as possible. This makes it more likely to survive than other plants. Both of these advantages help the living thing to be stronger.
For page 2: These adaptations are advantageous. The Toucan has a long and narrow beak that helps it get fruit other birds cannot get. This gives them access to more food which can help them outlive other birds. The Monstera plant has adapted so that it does not mold. This helps it stay healthy whereas other plants may grow mold. These two organisms have adapted so that they have one sure advantage that will help them live longer than other species. The advantages are different but they both serve the same purpose.

A fern is a flowerless plant that  has feathery or leafy fronds and reproduces by spores released from the undersides of the fronds.

Okay, now, what makes them different? Ferns are flowerlessFerns do not have seedsFerns are grouped into one divisonFerns have smaller speciesGymnosperms have seeds.Gymnosperms are grouped in  more than one divisonGymnosperms have a larger species.

Now, what do the have in common?They are both vascular They both have sporophyte dominant generation

cycads. Palm-like plants found mainly in tropical and subtropical regions.ginkgoes: maidenhair tree. One species: Ginkgo biloba; the maidenfern tree no longer living in the wild, and only found in cultivation.gnetophytes: mormon tea, welwitschia, gnetum.conifers: pines, spruces and firs.

Some types of ferns

Gymnosperms are different because they have seeds and ferns do not. Gymnosperms also have more than one divison.Both gymnosperms and ferns are vascular. They also both have sporophyte dominant generations. So this is what makes them similar and different.

are the benefits of dialysis worth the cost?

Answers

Answer:

The cost of alternative dialysis modalities for the treatment of end-stage renal disease (ESRD) was evaluated, using a societal viewpoint, in a regional nephrology program in south-western Ontario. The dialysis treatments compared were hospital hemodialysis, home hemodialysis, self-care hemodialysis, and continuous ambulatory peritoneal dialysis (CAPD). The participants were all patients treated by the same dialysis modality for the fiscal year April 1990 to March 1991. Fully allocated costs are expressed in 1993 Canadian dollars. The average costs per patient year were $88,585 for hospital hemodialysis, $55,593 for self-care hemodialysis, $44,790 for CAPD, and $32,570 for home hemodialysis. The dialysis treatment costs were $54,929 for hospital hemodialysis, $43,313 for self-care hemodialysis, $31,918 for CAPD, and $26,048 for home hemodialysis. These data quantify the magnitude of the differences between fully-allocated costs among the dialysis modalities in a regional nephrology program in Canada. The methodology used in this economic analysis can be applied to programs which differ in structure and scale. The breakdown of dialysis treatment costs into overhead, support department, personnel, supplies, and medication identifies potential areas for cost reduction strategies.

The Blacklegged Tick is a parasite of the White-Footed Mouse. The White-Footed Mouse carries the bacteria which cause Lyme Disease. The bacteria are spread to ticks that bite infected mice. If an infected tick then bites a human, the human can be infected with the bacteria and develop Lyme Disease. Scientists have proposed that increased human development has led to an increase in the White-Footed Mouse population which can lead to increased cases of Lyme Disease in humans.

Answering which scientific question would BEST support the scientist’s hypothesis?

D Miohippus​

Answers

Answer: I think the answer would be D miohippus

Explanation:

Miohippus would be found in the uppermost layer of rock. Therefore, option (B) is correct.

What is Miohippus?

Miohippus is an extinct genus of early horse that lived in North America during the Miocene epoch, around 23 to 5 million years ago. It was a small, three-toed horse that was slightly larger than its predecessor, Mesohippus.

Miohippus had a relatively short face, with a long, narrow skull and teeth that were adapted for grinding tough vegetation. It is believed that Miohippus was the ancestor of the modern horse, and that its evolution was characterized by an increase in size, a reduction in the number of toes, and changes in the shape of the skull and teeth that allowed for a more efficient grazing diet.

Please select the best answer from the choices provided

A

Answers

Answer:

D.

Mean: 24.8

Median: 26

Mode: 26

Explanation:

The mean is the average. To find the average, add up all the numbers and divide by the amount of numbers there are.

30 + 26 + 25 + 11 + 34 + 20 + 26 + 26 = 198

Now, we divide by how many numbers we started out with (8).

198 divided by 8 = 24.75, rounded would be 24.8

To find the median, you arrange the numbers from smallest to largest, and find the middle number like this:

11, 20, 25, 26, 26, 26, 30, 34

As you can see, the middle number is 26.

To find the mode, you arrange the number from smallest to largest, and find the number that appears more often.

11, 20, 25, 26, 26, 26, 30, 34

As you can see, the number 26 appears the most often.

So, we end up with:

Mean: 24.8

Median: 26

Mode: 26
