As many as 25 percent of the cowboys who participated in the Texas cattle drives were AFRICAN AMERICANS.
Cattle drive was a main economic activity in the Western part of America during the 19th century. The west were known for cattle breeding and they usually have to move these cattle from the home ranches to the rail-heads where they will be bought. The distance between these two points is always great and it may takes as much as two to three months before the distances are covered. The cowboy are the ones that drive the cattle to their selling points. Texas was particular successful in cow farming and as at that time about one fourth of the cows boys are of African American origin.<span />

Two proteins associated with a rare neurodegenerative disorder have been sequenced. Protein A contains many polar amino acids wi

GuDViN [60]

Answer:

Protein A can be a cytoplasmic and protein B can be a membrane protein.

Explanation:

The polar amino acid will have the hydrophilic side chain so they provide the hydrophilic nature to protein and thats why usually found on outer surface of water souluble proteins.

Cytoplasm is 80% water, so these proteins usually found in cytoplasm.

The non-polar amino acid will have the hydrophobic side chain and thus provide hydrophobic nature to protein and usually found in interior portion of membrane protein.

Plasma membrane is made up of hydrophobic lipids bilayer, so these proteins are usually found in plasma membrane.

Define and distinguish between diffusion and omosis

Dmitry [639]

Diffusion is the spontaneous movement of substances from a region of high concentration to a region of low concentration.

Osmosis is the passage of water molecules from a high water concentration region through a selectively permeable membrane to a low water concentration region.

In diffusion, selectively permeable membrane is neither required nor involved while in osmosis, it is involved.
