Answer: Viruses are composed of eight proteins. RNA. And ribosomes. Vi single stranded DNA. C. Double stranded DNA. And RNA. D. Single stranded RNA. A. E. RNA or DNA. Never both and a protein coat. It's a great answer. Here is e so virus has two components that all of them have nucleic acid and a protein caps it so this is their genetic material. It can be RNA or DNA. It can be single stranded or double stranded of Eva. But it's never a mixture of DNA and RNA. So it's one or the other and they have a protein caps it here the protein coats. So all viruses have these two components some also have a lipid envelope and those are called enveloped viruses. All of them have these two components. They don't have ribosomes. They need to use the host ribosomes translate their genes. There. I'm RNA is they may have single stranded DNA but they'll also have the protein caps it. And they could be R. N. A. Same for single stranded RNA. They could be single stranded DNA. Or double stranded DNA. And that MRS. For protein. And see it cannot be because this is a mixture of nucleic acids. And also another edition is they can have proteins that come along with them. For example. HIV will bring along reverse transcriptase inside the very um but they all at least definitely have RNA or DNA but not both. And a protein coat. All viruses will have that

Write and solve an equation that will help you figure out how much of the remaining pizzas will be eaten. Explain the steps you took to solve the problem. ned the aser
Answer: 4 1/4
Step-by-step explanation:
Convert 5 2/3 to an improper fraction. 3 x 5 = 15 + 2=17
17/3 x 3/4 = 51/12= 4 1/4 of the remaining pizza will be eaten
Answer:
4 1/4
Explanation:
convert 5 2/3 to an improper fraction.
multiply the improper fractions = 17/3 x 3/4 = 51/12
reduce fraction 51/12 to 4 1/4
4 1/4 is the total

Which of these organisms would most likely live in a intertidal zone?
A. algae
B. sunflower
C. chemosynthetic bacteria
D. Venus fly-trap
Answer:
a algae
Explanation:
it lives there in the ocean
Of these organisms, algae would most likely live in a intertidal zone.
How does algae survive in intertidal zone?Any organism that lives in the intertidal zone must be able to tolerate powerful waves and variations in moisture, temperature, and salt. Sea stars, snails, seaweed, algae, and crabs can be found in the intertidal areas of rocky shorelines. Many brown algae in the intertidal zone have alginic acid in their cell walls, which acts as a water-absorbing gel and prevents the algae from drying up during low tides. In environments with high nitrogen levels, intertidal macroalgae can also outgrow seagrasses. In certain situations, certain algae can be a nuisance. The blue-green algae, also known as cyanobacteria, are ephemeral in their growth and recurrence. They can form mats or filaments and are encrusting.learn more about intertidal zone here: https://brainly.com/question/1346004

What color(s) eyes do the children have? Explain your answer.
Answer:
See below ↓↓
Explanation:

The offsprings have a possibility of either Gg or GG genotypeHence, their offsprings will also have green eye color1)A sample of red blood cells are placed in an isotonic solution and viewed under a microscope. Then, sugar is added to the solution to create a hypertonic solution. The sample is then looked at under a microscope again. what happened to the red blood cells after the sugar was added to the solution?
A- The red blood cells released water through osmosis. The release of water helped the blood cells take in more sugar for energy.
B- The red blood cells absorbed water through osmosis. The absorption of water helped the blood cells take in more sugar for energy.
C- The red blood cells released water through osmosis. The release of water helped the blood cells keep a similar concentration of solutes as the outside solution.
D- the red blood cells absorbed water through osmosis. the absorption of water helped the blood cells keep a similar concentration of solutes as the outside solution.
2)Which of the following is an example of microevolution?
A- the formation of four new species of fish in a lake over thousands of years.
B- a mass extinction that occurs because of major environmental changes in a habitat
C- a change in the frequency of body color in a species of beetles
over time
D- the formation of two new species of rodent have been isolated by a mountain range
3) a species of dark green trees is spread over a very large terrain. over a long period of time, mountains form in this area and the trees became split by the new formation. later, the trees on the east side of the mountain are all light green.
Over time, the light green and dark green trees spread to a new field that is not separated by the mountains. both types of trees are seen in the same field. however, the trees cannot produce any fertile offspring together. which of the following provides the best explanation as to why the two populations of trees cannot produce fertile offspring?
A- the trees on the west side of the mountain retained their original phenotype that became unique to their population
B- the trees on the east side of the mountain developed a new phenotype, which made them unable to produce fertile offspring.
C- the trees on the east side of the mountain experienced many genetic mutations and recombinations unique to their population
D- the trees on the west side of the mountain could not adapt to the new barrier, which made them unable to produce fertile offspring.
The red blood cell will have released water in order to equalize concentrations on either side of the membrane.
Why did the red blood cell release water?The red blood cell in question was placed in a hypertonic solution. This means that the solute concentration outside the cell is higher than that of it's inside concentration. This mean that through the process of osmosis, the cell will release water in an attempt to dilute the outside concentrations and achieve a balance. This will likely cause the cell to decrease in volume.
Therefore, we can confirm that the red blood cell will have released water in order to equalize concentrations on either side of the membrane.

Answer:

Explanation:
The ureters are two tubes that drain urine from the kidneys to the bladder. Each ureter is a muscular tube that drains into the bladder. Smooth muscle contractions in the walls of the ureters, over time, send the urine in small spurts into the bladder, the organ where urine is stored before it can be eliminated.

Magnification is x100. What is the actual size of one of these epithelial cells?
Answer:
The results show a range of epithelial cell diameters from 8-21 microns with 97% of the measurements lying in the 9-17 microns range. Pleomorphism is marked. The mean cell size was 12.7 microns. Large differences exist in mean cell size between individuals, but no correlation was found with age, diabetes or cataract.
Explanation:
The magnification is x100, and we assume that the cell is 1mm when observed under the microscope, then the actual size would be 1mm divided by 100, which is 0.01mm or 10 micrometers.
The actual size of the epithelial cell can be calculated using the magnification factor and the observed size under the microscope.
The actual size of the epithelial cell can be calculated using the magnification factor and the size of the cell as seen under the microscope.
In this case, if the magnification is x100, and we assume that the cell is 1mm when observed under the microscope, then the actual size would be 1mm divided by 100, which is 0.01mm or 10 micrometers.
