In preparing a karyotype, a blood sample is centrifuged to separate the blood cells from the plasma. The plasma is discarded and a hypotonic solution is added to make the cells swell. The solution is centrifuged again. A drop of this material is added to a slide, dried, and stained. The slide is viewed and photographed. Based on this procedure where is the best place to discard the plasma?
Answer:
give a call to (512) 272-9387 and ask about energy
How was osmosis involved in stopping Clark's seizures?
Answer and Explanation: There is an increase in Na concentration in the matrix of the brain, which causes blood to move into the brain and increases the matrix pressure.
As a result, Clark's seizures were stopped using hypertonic osmosis.

50 PTS SCIENCE Acting in the role of an atmospheric scientist, write a paragraph describing the atmosphere and its layers for a weather website entry. Be sure to describe significant similarities and differences among the different layers.
Answer:
The Earth's atmosphere is divided into five layers. The Exosphere is about 10,000km from the earth where the space shuttle gets to. The thermosphere is about 700km from the earth where the Aurora Borealis region is located. Mesosphere about 80km from the earth where the metro shower region is located. Stratosphere about 50 km from earth weather balloons region. Lastly, the troposphere is 12km from the earth is where the planes reach. All of the layers are divided based on their temperature levels.

Describe the tropical rainforest, What is the weather like? What is the precipitation per year? What are the average temperatures?
Answer:
look below
Explanation:
Description: The tropical rain forest is one of the largest biomes on Earth. It is formed by many trees and other forms of vegetation. The weather here tends to be humid.
Weather: The weather in this biome tends to be in the warmer ranges, hanging around 70 to 80 degrees Fahrenheit. The area also maintains humidity all year long.
Precipitation: The tropical rain forest can receive anywhere from 80 inches to 400 inches of rain a year.
Temperatures: The temperatures here range from 70 to 80 degrees Fahrenheit or 21 to 30 degrees Celcius.
How was osmosis involved in causing Clark's seizures?
Osmosis, involved in causing Clark's seizures by exerting pressure on his brain, had an impact on Clark and caused him to experience a seizure.
What is osmosis?Osmosis is a process of distribution of transforming a substance or ions from the lower concentration to the higher concentration region. Osmosis happens against the concentration gradient, so it needs the energy to proceed.
We had to restore balance to the calf's brain and blood vessels in order to stop the seizure. Because Clark had more sodium in his matrix, which caused water to diffuse out of the vessels and into his matrix, osmosis was involved in his seizure.
Thus, due to the increased concentration of Na in the matrix of the brain, osmosis is involved in causing Clark's seizures.

Answer:
1.The probability of having purple flowers in the offspring is 75%.
A gene is the unit of inheritance found on the chromosomes. They often occur in pairs called alleles. A pair of alleles control the phenotype (observed traits) of an individual. Given two heterozygous parents that have purple flowers, let the gene for purple flowers be T and let the gene for white flowers be t. Using a punnet square as shown, there is a 75% chance of obtaining offspring having purple flower color
2.This means that each pea plant must have two sets of all genes, one inherited from each parent. For this mechanism to work, each germ cell must have only one gene set

state why gorillas and chimpanzees are separate species
Answer:
Gorilla and chimpanzee are two great apes that are endangered. Gorilla is less intelligent than chimpanzee. Further, they differ from the tribe and the genus they belong. Chimpanzee is closer to human than the gorilla does. Because they have larger brains than gorillas. And they share 98% DNA similarity with humans. Gorilla is a herbivorous ape while chimpanzee is an omnivorous ape. This is the difference between gorilla and chimpanzee.
What are the chances of the mating of two pink four-o-clock flowers producing all pink offspring?
A. 25%
B. 50%
C. 100%
D. zero
Answer:
100%
Explanation
If the two flowers both have same traits, for example pink and pink, the offspring will be pink. The only rare chance of this not being true is a mutation, but I assume that's excluded.
