Which are the special proteins in muscles that contract and relax to cause movement?

 

Visceral pain is a poorly localized, dull, or diffuse pain. It usually arises from the abdominal organs.

The principal hormone secreted by the corpus luteum is progesterone. Menstruation is triggered by a drop in the levels of progesterone.

The processes both osmosis and diffusion come under passive transport and require no energy. The movement of solute from the region of higher concentration to the region of lower concentration is nothing but diffusion.

The flowering plants, also known as angiosperms, Angiospermae or Magnoliophyta, are the most diverse group of land plants. These are also seed producing plants like gymnosperms. In Angiosperms seeds are in flowers.

In a nucleosome, the DNA is wrapped around a protein called histones and area in between them.

The movement of blood in the body is called blood flow. The blood flows through the vessels, tissues and organs. Blood flow to a tissue will increase if the level of carbon dioxide at the tissue increases.

The chief capacity of vitamin K is to help our blood clot so that we don't bleed too much.

Vitamin K is actually made up of two different types of vitamins, Vitamin K1 and Vitamin K2. They are both responsible for helping the blood to clot so that people do not bleed to death. Vitamin K1 can be consumed by eating leafy green vegetables, such as kale and spinach, as well as other vegetables, such as broccoli and collard greens. Meats, cheeses, and eggs can provide a great source of Vitamin K2.
