Sex-linked diseases are passed down through families through one of the X or Y chromosomes. X and Y are sex chromosomes.
Flu (influenza) viruses are divided into four broad categories: influenza A, B, C or D. Influenza A is the most common type. H1N1 flu is a subtype of influenza A.
Subtypes of influenza A are categorized based on two proteins on the surface of the virus, hemagglutinin (H) and neuraminidase (N). There are many H and N subtypes, and each one is numbered. All H and N flu subtypes are influenza A viruses.
Each influenza subtype has many different strains of influenza virus. Not all strains infect people. Subtypes of influenza A viruses currently found in people are strains of H1N1 and H3N2. Each year's flu vaccine includes varieties of both of these strains and influenza B.
i hope this helps. please mark brainliest if it does :)
Hdl has a high proportion of protein, which makes it the heaviest (most dense) lipoprotein.
The five main subgroups of lipoproteins include high-density lipoprotein (HDL). All fat molecules (lipids) are transported throughout the body by lipoproteins, complex particles made of several proteins that float outside of cells and move throughout the body's fluids.
Through both direct and indirect channels, HDL mostly delivers cholesterol to the liver or to organs that can produce steroid hormones, such as the testicles, ovary, and adrenal glands.
Scavenger receptor BI (SR-BI), an HDL receptor that facilitates the selective uptake of cholesterol from HDL, is one type of HDL receptor that removes HDL. The indirect pathway, which is mediated by the cholesteryl ester transfer protein, is likely the most significant one in humans (CETP).
Following conversion into bile acids, the cholesterol supplied to the liver is either directly or indirectly excreted into the bile and, consequently, the intestine.

The first and last sounds most reasonable, but I will go with the last one.
It has the largest source of warm water.
