Answer:
A
Explanation:
The procedure that could be used to make sure that the puppies all have long hair is selectively breeding two dogs with long hair to produce long-haired puppies. Therefore, the correct option is C.
What is selective breeding of dogs?Selective breeding involves mating two dogs with desirable traits (in this case, long hair) in order to produce offspring with those traits. Over time, this can lead to a population of dogs that consistently exhibit the desired trait.
Genetic engineering (option B) and cloning (option D) are not currently practical or ethical methods for producing long-haired Chihuahuas. These techniques are complex, expensive, and not yet reliable for producing specific traits in animals. Additionally, the ethics of these methods are still under debate.Therefore, the correct option is C.

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.

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.
