Answer:
Patients with problems related to cells that repair a cut or malfunctions in the development of the child's reproduction are due to failures in the process of cell division —in somatic cells or gametes— which is mitosis and meiosis.
Explanation:
Mitosis and meiosis are processes of cell division that are necessary for the development of life. Both processes involve obtaining two daughter cells from a progenitor cell, where the genetic information contained in the original cell is transmitted to the cells produced.
Through mitosis, somatic cells —diploids— can multiply, allowing the growth and development of an individual, the repair of damaged tissues and the availability of cells needed by the body, such as blood cells. Meiosis, unlike mitosis, occurs in sex cells, giving rise to gametes. These cells have half of the chromosome load —haploids— and when two of them join, a diploid cell is formed, the zygote.A failure in the process of cell division, whether mitosis or meiosis, can have as consequences:
Mitosis: alterations in the growth and development of a living being, as well as difficulty in regenerating tissues, for example cells that cannot repair a cut. Meiosis: failures in meiotic division can cause chromosomal mutations, which alter the body structure or function determined by the altered chromosome, which results in a child's developmental malfunction.Any alteration in the process of cell division can generate changes or alterations that affect an individual, limiting the functions it can perform.
Which is the final event that occurs when a star is forming?
The outer layer of the star expands.
Gravity pulls gas and dust together.
A black hole forms as the core collapses.
Nuclear fusion begins under high pressure.
Answer:
D. Nuclear fusion begins under high pressure.
Explanation:
A star is a giant astronomical or celestial object that is comprised of a luminous sphere of plasma, binded together by its own gravitational force.
Some of the examples of stars are;
Canopus.Sun (closest to the Earth)Betelgeuse.Antares.Vega.Stars are typically made up of two (2) main hot gas, Hydrogen (H) and Helium (He). The chronological order in which the formation of a star occur are;
1. Gravity pulls gas and dust together to form dense cores.
2. A protostar forms as mass increases.
3. Nuclear fusion begins under high pressure.
Hence, the final event that occurs when a star is forming is that nuclear fusion begins under high pressure.

What happens when enzymes are heated to a high temperature? The enzymes die.
The enzymes' amino acid sequence changes.
The enzymes remain the same.
The shapes of the enzyme are denatured.
Answer:
The shapes of the enzyme are denatured
Explanation:
High temperatures will break the forces that hold them together and control the enzymes.
The enzyme, including it's activity site will eventually change shape and the substrate will no longer fit; proving them ineffective.

Whenever I see the word artichokes I feel nauseous and scratchy. I once ordered a pizza with artichokes and cheese on it. I have never been allergic to artichokes before.

I said they were square. She said I had hives and to take benedryl. - the sight of artichokes - feeling nauseous and scratchy from the allergic reaction - allergic reaction (hives) - feeling nauseous and scratchy from seeing an the word "artichokes" A.

I'm not sure what's the answer, but since I love helping I'mma try to help you out aha. But uh I think it's B. If I'm wrong I'm sorry :))
The artichoke is a huge, thistle-like perennial plant of the aster family (Asteraceae), often known as the globe artichoke or the French artichoke, and its flower buds are farmed for their gastronomic qualities.
The young bloom bud of a thistle is an artichoke. It is considered a vegetable in cuisine and is consumed as such. The plant, an aster, is plucked for its buds rather than its flowers. It takes some effort to get to the edible sections of an artichoke, which makes it a difficult vegetable to prepare.
What are some examples of UCS, UCR, and CS?
The chemotherapy medications are the unconditioned stimulus (UCS) in this scenario, the vomiting is the unconditioned response (UCR), and the doctor's office is the conditioned stimulus (CS) after being matched with the UCS and UCR.

12. Some viruses attack cells by inserting their own DNA into the host cells’ DNA. Why might it be simpler for these viruses to attack prokaryotic cells than eukaryotic cells A. Prokaryotic cells have less DNA than eukaryotic cells.
* B.
The cell wall in prokaryotic cells is a less effective barrier.
* C.
The rapid growth of prokaryotic cells generates more viruses.
* D.
Unlike eukaryotic cells, prokaryotic cells do not have a nucleus.
Answer:
DNA in eukaryotic cells lie within the nucleus. This DNA has a membrane protecting it from the outside. This means that the virus would have a harder time getting to the DNA to insert its DNA in a Eukaryotic Cell.
I hope this is helpful somehow
Unlike eukaryotic cells, prokaryotic cells do not have a nucleus.
What are prokaryotic cells and eukaryotic cells?Prokaryotes are organisms whose cells lack a nucleus and other organelles. Eukaryotic cells have a membrane-bound nucleus.
Eukaryotic cells have a separate organelle named nucleus (plural: nuclei) which is a double membranous structure meant for the storage of genetic material i.e. chromosomes (DNA). Prokaryotes on the other hand have an irregularly shaped structure named nucleoid instead of nucleus. All the genetic material of the prokaryotes is within the nucleoid. Unlike nucleus, nucleoid does not have any nuclear membrane & it is spread in the cytosol freely.
Hence, option D is the correct answer.

Which step in the process of photosynthesis is dependent on light energy?
A.splitting of water into hydrogen and oxygen
B.combining carbon and oxygen into carbon dioxide
C.splitting carbon dioxide into carbon and oxygen
D.combining hydrogen and oxygen to form water
Answer:
D. Combining hydrogen and oxygen to form water.
Explanation:
The process of photosynthesis which is dependent on light energy is the
combining of hydrogen and oxygen to form water.
Photosynthesis involves the reaction between carbondioxide and water to
form Starch and oxygen. The water molecules however have to be split
because of movement of electrons in which the water become oxidized and
carbondioxide reduced.
This process however have to be done in the presence of sunlight which
serves as a precursor.
