Answer:HIV finds the white blood cells, called CD4 cells. HIV gets inside the CD4 cell and makes copies of itself. Then, HIV kills the CD4 cell and the new HIV copies find other CD4 cells to get inside and start the cycle again. HIV kills immune system cells that help the body fight infections and diseases.
Explanation:
Answer/Explanation:
All cells are not the same because not all cells contain membrane-bound organelles.
Prokaryotic cells lack membrane-bound organelles. In contrast, eukaryotic cells contain membrane-bound organelles like an endoplasmic reticulum, lysosomes, and importantly, a nucleus.
The nucleus is where genetic information (DNA) is stored. However, it is only present in eukaryotic cells. Prokaryotic cells do not possess a nucleus, the DNA is found in the cytoplasm.
Answer:
sea sponge
Explanation:
everything else is symmetrical, sea sponges are known for being whacky shapes and sizes and are never symmetrical
The right answer is 20 aminoacids per second.
Transcription is a mechanism for synthesizing RNA from DNA.
Translation is a mechanism for synthesizing a polypeptide sequence from mRNA by converting the nucleotide triplet (codons) to amino acids.
So if one amino acid corresponds to three nucleotides. The polypeptide synthesis rate should be 20 amino acids per second for 60 nucleotides per second.
3 nucleotides ==> 1 amino acid
60 nucleotides ==> 60/3 = 20 amino acids.
