AIDS attacks white blood cells, damaging the immune system and making the infected individual more susceptible to illness. White blood cells are the ones that fight off harmful bacteria, so without them you could even end up in the hospital or die from a common cold.
Answer:
They are veins and arteries. The primary function of arteries is to transport highly oxygenated, nutrient-rich blood from our hearts and distribute it to the rest of our body. Veins, on the other hand, are used to pump much-needed blood back to the heart.
Answer:
AWWWW thats sad i get it but dont know it
Explanation:
The specific electrophoretic diagram required to determine the DNA sequence is not found here but this technique refers to Sanger sequencing.
<h3>What is Sanger sequencing?</h3>
Sanger sequencing is a technique used in molecular biology and genetics to determine the linear order of nucleotide bases in a given genomic sequence, which is fundamental to identifying alleles in a genome.
This technique (Sanger sequencing) is based on the use of certain analogous nucleotides that stop the process of amplification, which can be subsequently evidenced in an electrophoresis gel.
In conclusion, the specific electrophoretic diagram required to determine the DNA sequence is not found here but this technique refers to Sanger sequencing.

Answer:
The correct answer is - the placenta, the site of exchange of materials between the mother and the fetus.
Explanation:
In the given diagram there is a representation of a human embryo developing in the uterus. Different parts are numbered and the number three represents the site of exchange of materials between the mother and the fetus and this organ is called the placenta. It is the organ that develops between fetus and uterus during pregnancy that allows substances such as nutrients, to diffuse from the mother's blood to the fetus and connected by the umbilical cord.
