Answer: for me the best option is D.
Explanation: lets explain this.
Cellular respiration begins with a process that divides the glucose within the cells making it readily available as a source of energy. This process can occur without oxygen (anaerobic respiration) or in the presence of oxygen (aerobic respiration). Anaerobic respiration generates more excess waste (lactate) than aerobic . Besides, high levels of lactate build within the muscle cells. Excess lactate slows the cellular respiratory process and is experienced as a burning sensation in the muscles if exercise continues.
Answer:
forest ecosystem is whereby the organism live together and interact with each other and their environment. The biodiversity in this ecosystem is reducing due to the following factors:
1. deforestation: if most of the trees in the forest are been cut down without replacement it will affect the animal living there. especially herbivores, they feed on this plant and use it as a hideout.
2. bush burning: if the bush is burnt it may lead the animals to ran away for there safety and some may die of hunger, and some trees and plants may also become weak and die therefore reducing food for other animals.
3. Climate change: Climate change is one of the reasons. As deforestation may lead to climate change and many other factors, Without transpiration and evaporation cloud won't be form and there will be no rain which may lead to draught and finally animal will die and others will migrate.
possible solution to this
1. Avoid deforestation, and bush and plant more trees.
2. the government can also make laws concerning deforestation, bush burning, burning of fosil fuels and tires to avoid climate change.
Answer:
DNA is a long polymer with a phosphate backbone and deoxyriboses. Adenine, guanine, cytosine, and thymine are the four nitrogenous bases. The backbone of RNA is made up of ribose and phosphate. Adenine, guanine, cytosine, and uracil are four nitrogenous bases.
So DNA is two stranded, RNA is single stranded.
