Ozone in the stratosphere is a toxic pollutant that can cause tightness or shortness of breath is a true statement.
What is ozone layer?One layer of the stratosphere, the second layer of the Earth's atmosphere, is the ozone layer. The layer of insulating gases that clings to our planet is known as the stratosphere.
A small layer of the Earth's atmosphere called the ozone layer absorbs nearly all of the sun's harmful UV energy. Areas of the ozone layer degradation are frequently referred to as "ozone holes." That is incorrect. Damage to the ozone layer is more akin to a very thin patch than a hole.
Therefore, Ozone in the stratosphere is a toxic pollutant that can cause tightness or shortness of breath is a true statement.

What would happen if cells never changed?
Options:
1. All cells would become blood cells.
2. Meristem cells would form.
3. All cells would be exactly the same.
4. Cell differentiation occurs.
Answer: 2. Meristem cells would form.
Explanation:
Permanent cells are cells that are incapable of regeneration. These cells are considered to be terminally differentiated and non-proliferative in postnatal life. This includes neurons, heart cells, skeletal muscle cells and red blood cells.

PLEASE ANSWER ASAP.
Explain what friction, corollas, and a low pressure gradient does to an air parcel. IF YOU CAN PLEASE GIVE A SHORT ANSWER.
Answer:
sorry big answer Answer with Explanation:
Coriolis Force - refers to the fictitious force that acts perpendicularly to the direction of a rotating motion.
Air parcel - refers to a body of air that is "imaginary."
Pressure gradient - the change in pressure across a given distance.
Pressure gradient force - the net force that is being directed from high pressure to low pressure.
When an air parcel is at rest, the pressure gradient force acts upon it. It will then move from high pressure to low pressure.
However, when the air parcel starts to be in motion, its direction will be changed with the help of the Coriolis force. Thus, it moves to the right side of the Northern hemisphere.
Once the speed of the wind increases, the change in direction of the air parcel increases. This happens until the pressure gradient force and the Coriolis Force are equal in magnitude. When this happens, the wind will start blowing parallel to the points of equal pressure. The wind will now then be referred to as in "geostrophic balance."
When friction happens, the geostrophic balance breaks. The flow of the wind will be slowed down. This means that the Coriolis force will also be lessened. The air parcel will then move towards the lower region.

Describe how ions, water and sugar are obtained and transported
through plants. In your answer you should refer to materials moving upwards in a plant and to
materials moving downwards in a plant
Answer:
Explanation:
Water moves through the xylem in a stream called a transpiration stream, up to the leaves of the plant. Sugar is made during the process of photosynthesis. Unlike water and ions, it travels through the plant via the phloem, moving up and down through the plant.
Explain how the rate of cooling magma affects the size of
the crystal that form.
Answer: When magma cools, crystals form because the solution is super-saturated with respect to some minerals. If the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large.

in turkeys the allele for brown feather is dominant to the allele for a yellow feather. if two heterozygous turkeys mate and produce offspring, what is the probability of an individual offspring having yellow feather?
50%
0
25%
100%
Answer:
50%
Explanation:
trust me because the heterozygous is so weird but I know this.
In turkeys the allele for brown feather is dominant to the allele for a yellow feather. if two heterozygous turkeys mate and produce offspring, than the probability of an individual offspring having yellow feather is 50%. Thus, option A is correct.
What will be produced in turkeys a dominant gene?In turkeys a dominant gene, R, produces the familiar bronze color; its recessive allele, r, results in red. Another dominant gene, H, results in normal feathers; its recessive allele, h, produces feathers without webbing, so that they resemble tufts of hairs.
Two bronze turkeys with normal feathers were mated, and their offspring consisted of eight bronze with normal feathers, three bronze with hairy feathers, two red with normal feathers, and one red with hairy feathers.
Since, this offspring received a recessive red, r, allele from each parent and a recessive hairy, h, allele from each parent, both parents must heterozygous for both characters: RrHh.
Therefore, In turkeys the allele for brown feather is dominant to the allele for a yellow feather. if two heterozygous turkeys mate and produce offspring, than the probability of an individual offspring having yellow feather is 50%. Thus, option A is correct.
