Answer:
a cell that has a specific job or function that carries out. -found in multicellular organisms (made of many cells) -once a specialized cell, it can not become any other cell.
Explanation:
Once a cell becomes specialized, it cannot become any other type of cell. This is because, this cell cannot form stem cells which have the ability to form different types of cells in the body.
Specialized cells are the cells which are designed to carry out a particular role in the body, such as that of red blood cells which are designed to carry oxygen gas in the blood. Nerve cells help in the contraction of muscles or the relaxation of muscles according to what the specific job we need them to do.
Cell differentiation is the process of specialization which lead to the formation of different organs such as brain, heart, and all other tissues from the single-cell zygote and the primitive, three-layered embryo.
Once a cell became specialized in the body, it was referred to as terminally differentiated cell. These cells cannot be turned back into a stem cell with the potential to become any type of cell in the body.

B. Asexual reproduction has 1 parent with identical offspring
C. Asexual reproduction has 2 parents with similar offspring
D. Asexual reproduction has 2 parents with identical offspring
Answer:
A.)
Explanation:
We know that asexual means one. In this case, it would be A
., because there is one parent producing the cells. There may be some differences, which would make similar offspring, not identical offspring. So the answer would be A.) :) Hope this will help!
Which of the following would change the allele frequencies of a population?
A)Lack of mutation in the DNA
B)Mating is random with no selection occurring
C)A population on an island remains isolated and no one leaves or moves on the island
D) All of the answer choices would change allele frequencies of a population.
Answer: option B.
B)Mating is random with no selection occurring
Explanation:
This will cause change in allele frequency because it's a genetic drift which is the change in the frequency gene variant that is common in a population due to random sampling or random mating. When this occur it lead to a change in percentage or incidence of gene variant in a population since there is random sampling without any selection.
Mating is random with no selection occurring, which would change the allele frequencies of a population.
What would increase the allele frequency in a population?Natural selection can drive microevolution, or a difference in allele frequencies over time, with fitness-increasing alleles becoming more common in the population over generations.
Thus, option"B" mating is random with no selection occurring.

How do ribosomes use mRNA and tRNA to assemble proteins?
Ribosomes are cellular organelles that are responsible for assembling proteins by using messenger RNA (mRNA) and transfer RNA (tRNA).
How do we explain?mRNA is a molecule that contains the genetic code for a protein. It is transcribed from DNA in the nucleus of the cell and then transported to the ribosome.
tRNA is a molecule that carries amino acids to the ribosome. Each tRNA molecule is specific for one amino acid.
The ribosome reads the mRNA molecule and matches the codons on the mRNA to the anticodons on the tRNA molecules. The anticodon is a three-nucleotide sequence on the tRNA molecule that is complementary to the codon on the mRNA molecule.

I WILL REPORT IF U JUST DO IT FOR POINTS AND U JUST PUT NONSENSE
Answer:
1. The two main cell types are prokaryotic and eukaryotic. Prokaryotic cells lack a nucleus and other membrane-bound organelles.
2. Cytoplasm: Cytoplasm contains enzymes that break down waste. It also provides shape to the cell. Cytoplasm enables organelles to remain where they are.
Nucleus: The nucleus controls activity inside the cell. It also carries genes.
Mitochondria: Mitochondria generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate.
Endoplasmic reticulum: The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function.
Ribosomes: The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make proteins.
Golgi apparatus: A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell.
Vesicles: Transport vesicles help move materials, such as proteins and other molecules, from one part of a cell to another.
Lysosomes: A lysosome is a membrane-bound cell organelle that contains digestive enzymes. Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria.
Cell membrane: The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
3. An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.
4. Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and peroxisomes. These structures include: chloroplasts, the cell wall, and vacuoles.
