Answer:
The first one Glycolysis.
Explanation:
Sometimes it is in the absence of oxygen.
Answer:
Clear cutting can result in increased carbon dioxide levels in the atmosphere.
Explanation:
Clear cutting of trees increases the amount of carbon dioxide. Trees are useful in balancing the concentration of carbon dioxide in the atmosphere. They trap carbon dioxide that is used during photosynthesis in the manufacture of carbohydrates. When there is deforestation, the excess carbon dioxide rises to the atmosphere forming a blanket that traps excess heat which causes global warming or greenhouse effect. The excess heat warms the aerth surface.
Answer:
Reproduction is one of the most important characteristics of living beings, because -
- The existence of any species is dependent on the reproduction because no living being is immortal.
After death of a being of one generation,the existence of that died being is completed by the newborns of the next generation.
And,the birth of newborns of next generation is only possible by the reproduction.
- The variation and mutation in the biological characteristics is often necessary which is only possible by reproduction through many generations.
- When a living being becomes old, it's become unable to do normal tasks like collection of food, finding shelter etc,at that moment,the newborns of next generation do the necessary jobs.
And as mentioned before,these newborns are only possible due to reproduction.
The correct answer is Metaphase
Answer:
By one week after conception, the multiplying cells have divided into outer cells enclosing a mass of inner cells. The inner cells will become the embryo.
Explanation:
By week one, the outer cells will give the trophoblast, which will later become the placenta, while the inner cells will form the embryoblast, which will become the embryo. Then the inner cells will be in one end, and in the other one, there would be the blastocele, which is a space with fluids. This process takes place in the fallopian tube and is part of the segmentation process.
