The earth's atmosphere consists mainly of nitrogen and oxygen with smaller proportions of other gases such as carbon dioxide. The amount of carbon dioxide in the atmosphere is maintained through a balance between processes such as photosynthesis, respiration and combustion. However this balance is being affected by human activities which are polluting the atmosphere.
The proportion of these gases in the atmosphere is as follows: nitrogen is the most abundant at 78%, oxygen is next at 21%, while others include carbon dioxide at 0.037% and argon at 0.9 % .
Answer:
Vascular have a system that is intricate and the plant can move water to distribute it to the whole plant. Vascular plants are able to grow bigger due to this ability. Example of this would be a tree or a flower Non vascular plants are usually small plants that are close to the ground.
Explanation:
Bryophytes, which evolutionarily precede tracheophytes, are plants that lack true vascular tissues by which to circulate liquids. These plants include mosses, hornworts and liverworts. Tracheophytes, which comprise about 93 percent of all land plants, all possess vascular systems that permit the internal circulation of liquids and nutrients.
If the comet were to strike the planet, the impact energy would be about 300 times that of the asteroid collision that was thought to have caused the Cretaceous-Tertiary extinction that killed the dinosaurs about 65 million years ago.
If there is too much of glycogen and fat stored in a cell can be toxic. It damages the organs and leads to diseases.
Explanation:
Glycogen is stored in the liver or muscle tissue, the diseases affect functioning of the liver, kidney and the muscles. These diseases are mainly caused by genetic enzyme that is inherited from both parents.
The glycogen storage diseases are Von Gierke disease, Pompe's disease, Cori's disease, Hers' disease. The symptoms of this glycogen storage diseases are Low blood sugar, An enlarged liver, A swollen belly, weak muscles.
It is a metabolic disorder caused by enzyme deficiencies affecting glycogen synthesis in muscles.
