The correct option is D.
Cellular respiration is the process by which the body breaks down the sugar molecules that are eaten in food with the aid of oxygen and covert them into energy, carbon dioxide and water are also produced as by products. Cellular respiration and fermentation are both involved in the breaking down of sugars but cellular respiration occurs in the presence of oxygen while fermentation occurs in the absence of oxygen. Carbon dioxide is breath out by the lungs during cellular respiration.
Euglena move by a flagellum<span>, which is a long whip-like structure that acts like a little motor. The </span>flagellum<span> is located on the anterior (front) end, and twirls in such a way as to pull the cell through the water. It is attached at an inward pocket called the reservoir</span>
Answer& Explanation:
Angiosperm is more advanced due to the mechanism of protection it has since developed as opposed to its predecessor, gymnosperm. Angiosperms could be deemed the inventors of animal-mediated pollination or dispersal, whereas gymnosperms mostly depend on wind-mediated pollination (which is far more of a gamble than animal mediated).
1) Angiosperms seeds are enclosed in fruits, which increases the chances of dispersal by either wind, water, or animals. Animals can eat the fruit and disperse the seeds via feces or by brushing the fruit off of their fur coats new areas of the terrain.
2)The development of flowers. Flowers are especially important because depending on the flower it can attract a set species of animals in order for pollination to occur. That species of animal could only focus on those few flowers and would allow the female part of the flower to receive pollen (produced by the male part of the flower) from all over the place. This theory is also applicable to animal mediated fruit dispersal.
