Chickens have 78 chromosomes.
Answer:
Birds can keep themselves warn without any external heat source which is not the case with reptiles and amphibians
Explanation:
Birds are able to generate heat means they are endothermic. They generate heat through various metabolic processes. They have air pockets beneath their feathers to insulate their bodies during cold temperatures. Feathers which are modified reptilian scales help birds to streamline their exterior body and structure feathers in a way that it insulates the body.
<span>Translation
</span>Remember that transcription happens in the nucleus as it changes from DNA
to mRNA. In translation,
the mRNA first has to leave the
nucleus and go into the cytoplasm of the cell.
The process of translation actually occurs in the cell’s ribosomes.
<span>
</span>The process of translation uses the genetic code on the mRNA strand to
direct the construction (making) of a protein molecule. <span>
</span>1. A ribosome attaches to an mRNA
molecule in the cytoplasm.<span>
</span>2. As each codon passes through the
ribosome, tRNA molecules bring the matching amino acids into the ribosome. Each tRNA has a set of 3 unpaired nitrogenous
bases called an anticodon which matches up with the codon coming through the
ribosome. So one end of a tRNA has an
anticodon and the other end carries the amino acid which is how the code is
translated.<span>
</span>3. The ribosome and the rRNA
molecules it contains attach the amino acids together as they are being
translated. The protein chain will keep
growing until the ribosome reaches the stop codon on the mRNA. At that point, translation is done and the
ribosome lets go.
Hope this helps!!!
Answer:
Food must be broken down into nutrients for the body to use for energy, development, and cell repair. Before the blood absorbs and transports nutrients to cells in the body, food and drink must be broken down into smaller nutrient molecules.
Answer: DNA
Explanation:
DNA also referred to as deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Almost every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus.
