Earth's history. In the worst one, 250 million years ago, 96 percent of marine species and 70 percent of land species died off. It took millions of years to recover.
Answer:
plasmodesmata
Explanation:
Plasmodesmata are channels between adjacent plant cells, while gap junctions are channels between adjacent animal cells. However, their structures are quite different. A tight junction is a watertight seal between two adjacent cells, while a desmosome acts like a spot weld.
Answer:
becomes accumulated in the blood
Explanation:
The processing of alcohol is constant in every individual. The rate at which alcohol stays in someone's body is determined by how much of it is consumed.
Alcohol enters the digestive system once ingested and travels to the stomach and small intestines. The amount of alcohol absorbed in the small intestine enters directly to the bloodstream. Once in the blood, alcohol is circulated with it. The liver is responsible for the metabolic elimination of most (about 95%) of ingested alcohol from the body. If an individual consumes more than this, the system becomes saturated, and the additional alcohol will accumulate in the blood and other tissues until it can be metabolized. If this happens frequently or too fast, damage to the brain and tissues of the body can occur.
Blood Alcohol Concentration (BAC) depends on the amount of alcohol consumed and the rate at which the individual's body metabolizes alcohol. Because the metabolism of alcohol by the body is constant, taking in alcohol at a rate higher than the rate of metabolizing it results in a cumulative effect and increase in the blood alcohol concentration.
It is important to note that, the more one drinks the longer alcohol stays in the system.
Answer:
Connective tissues that attach muscle to bone.
Explanation:
The tissues that connect, bind, support or separate other tissues or other organs are called Connective Tissue. There are three major types of connective tissue -
- Loose connective tissue
- Dense connective tissue
- Specialized connective tissue
Tendon and Ligaments come under dense connective tissue category. Tendon is a fibrous connective tissue and connects muscles to bone. It has capability to withstand tension.
Ligaments connect bones to bones.
