Answer:110
Explanation: 220 x .5
Which solution has cells that are hypertonic?
Answer:
hypotonic solution
Explanation:
Answer:
Compared to fresh water, salt water is a hypertonic solution. This means that for cells to function, they must contain a cytosol that is a more hypertonic solution than salt water. Sea turtles, for example, live in a much more hypertonic solution compared to freshwater turtles.

both objects?
A. They are made of only one kind of atom.
B. They have the same shape.
C. They have the same mass.
D. They have the same number of atoms.
help plz
Answer:
A
Explanation:
If they are only made of one element (which I'm assuming they are because the question doesn't say otherwise), then they must all be made of the same kind of atom. Only one kind of atom (in terms of protons) corresponds to one element.
(_______) stars, however, will last for several billion years, because
they burn their fuel much more slowly. *
Answer:
Smaller
Explanation:
Life Cycle of a Star
Stars are formed in clouds of gas and dust, known as nebulae. Nuclear reactions at the centre (or core) of stars provides enough energy to make them shine brightly for many years. The exact lifetime of a star depends very much on its size. Very large, massive stars burn their fuel much faster than smaller stars and may only last a few hundred thousand years. Smaller stars, however, will last for several billion years, because they burn their fuel much more slowly.

Do plants and animals both use cellular respiration? Explain.
Answer:
yea
Explanation:
just took a test today
Answer: yes
Explanation: Plant cells respire the same way animal cells do, but respiration is only one part of the process. To survive, plants also need another chemical reaction called photosynthesis. While both plants and animals carry out cellular respiration, only plants conduct photosynthesis to make their own food.

Answer:
The correct answer would be - a condition that is not similar to the normal physiological function of a healthy body.
Explanation:
The disease is the condition where the deviation from the normal physiological function of an organism's body. It is associated with any abnormality in the structural or functional condition of the body.
For instance cancer, the body leaves its normal function of killing cells that are not following the norms and cause uncontrolled cell division

Explanation:
Consider two cells: a stomach-lining epithelial cell dividing more than
twice a day and a liver cell dividing every year or two. Which cell is
likely to be in Go phase and why?
Answer:
A liver cell
Explanation:
The cell that is most likely to be in G0 phase is the liver cell. That is because it only divides every year or two. However, a stomach-lining epithelial cell divides more than twice a day which means that it wouldn't usually be in the G0 phase.
hope this helps and is right :)
p.s. I really need brainliest
The cell that is likely to be going in Go phase is liver cell as it is the phase in which the cells that stops dividing either temporarily or permanently enters.
What is Go phase?The Go phase denotes a cellular state that occurs outside of the replicative cell cycle.
Traditionally, cells were thought to enter G0 due to environmental factors such as nutrient deprivation, which limited the resources required for proliferation. As a result, it was regarded as a period of rest.
Only 1 hepatocyte in 20,000 (0.005%) in a healthy adult liver is in the cell cycle.
The remainder are dormant, in the G0 state. Hepatocytes reenter the cell cycle after partial hepatectomy, progressing from the G0 to the G1 phase.
The liver cell is most likely to be in Go phase because it is the phase in which cells stop dividing either temporarily or permanently.
Thus, liver cell will enter Go phase.

Which will most likely cause an increase in the frequency of genetic mutations in
humans?
А
increased exposure to mold spores in the air
B
increased exposure to the rising levels of atmospheric CO2
с
increased exposure to bacteria in drinking water
D
increased exposure to X-rays
Answer:
Increased exposure to X-rays
Explanation:
X-rays shoot harmful radiation through your body, that's why when you go to the dentist or other places and they take a X-ray they give you a lead vest to protect your organs from unneeded radiation.
hope this helps :)
Increased exposure to X-rays is the most likely cause of an increase in the frequency of genetic mutations in humans (Option D).
A mutation is any alteration in the nucleotide (DNA) sequence of the genome in the cells of an organism.Mutation can be caused by physical factors (e.g., X-rays) or chemical agents (e.g., pesticides such as DDT).X-rays are well known to cause mutations by breaking covalent bonds in DNA, which may be erroneously repaired, thereby leading to deletions of nucleotides.In conclusion, increased exposure to X-rays is the most likely cause of an increase in the frequency of genetic mutations in humans (Option D).

why is it important that we take precautions against the coronavirus spread?
Energy that is carried by electric current is what energy
Answer: electrical energy
The faster the charges move, the more electrical energy they carry. As the charges that cause the energy are moving, electrical energy is a form of kinetic energy. Lightning, batteries and even electric eels are examples of electrical energy in action!Electrical energy can be either potential or kinetic energy since it's created from an electric charge flow. Continuing with the example of a battery, we know it has electrical potential energy while charging.

How does mRNA help in the differentiation of structures as an organism develops?
A. mRNA creates the amino acid chain that will eventually code for the specific protein that makes up a specific organ.
B.mRNA packages the proteins and takes them out of the cell
C.mRNA takes the DNA code to the ribosome so that the specific protein can be made that makes up a specific organ
D.mRNA is stored in the nucleus and carries the genetic code to make all of the specific structures of the body
Answer:
answer is part (C)
Explanation:
mRNA takes the DNA code to the ribosome so that the specific protein can be made that makes up a specific organ
mRNA takes the DNA code to the ribosome so that the specific protein can be made that makes up a specific organ. Thus the correct option is C.
What is mRNA?
Messenger RNA is referred to as a type of single-stranded RNA which involved in protein synthesis. mRNA is made from a DNA template during the process of transcription (formation of protein from DNA to RNA).
The role of mRNA is to carry protein information from the DNA in a cell’s nucleus to the cell’s cytoplasm (watery interior), where the protein-making machinery ribosome reads the mRNA sequence and translates each three-base codon into its corresponding amino acid in a growing protein chain.
