makkiz [27]4 years ago
5 0

Answer:most protozoa (prevalently attached ciliates) can only graze on suspended bacteria and particles; in this way they have a significant effect on the effluent quality.

Explanation:Even though some protozoa (crawling ciliates and other forms) can eat flocculated bacteria, most protozoa (prevalently attached ciliates) can only graze on suspended bacteria and particles; in this way they have a significant effect on the effluent quality.

Give two reasons why it is better for human muscle cells to produce energy through aerobic respiration than through anaerobic re
NISA [10]
Anaerobic respiration (without oxygen) would caused muscle cells to produce lactic acid. This causes the muscles to ache and in the long term, damages them. Also anaerobic respiration releases far less energy (ATP) than aerobic respiration. So it is best for muscle cells to respire aerobically as they need more energy.

Sveta_85 [38]

Answer:

Inhibits

Explanation:

Some mechanisms are essential for maintaining homeostasis in the human body. One of the most used mechanisms by our body is the negative feedback system. It causes a negative change from the initial change. As mentioned in the question, this often happens in the hypolamo-pituitary axis, such as when the adrenal cortex produces cortisol, this same cortisol inhibits the adenohypophysis and hypothalamus. It's also important to mention that deregulation in this process can lead to an undue chronic increase in cortisol and can lead to diseases such as anxiety disorder.

AlexFokin [52]

Answer: the rate of pollination of flower, in a field next to a pond with no fish, will DECREASE.

Explanation:

POLLINATION is defined as the process by which flowering plants, through the aid of external agents such as insects,wind, water and other animals, are able to transfer pollen grains from an anther to a receptive stigma. Insects are the most common pollinators. They visit flowers to obtain nectar and pollen as source of food. Flowers use various features, such as colour and scent, to attract and guide insects to the food source within them. In the process of reaching their source of food, insects bring about pollination.

From the study conducted by scientist in Florida, eight(8) ponds where subjected to the the study. The first four (4) ponds had species of fishes that fed on dragonflies and dragonfly larvae, hence the reason for a decrease in the population of the dragon flies in the area around it. While the remaining four (4) ponds had NO fish and the area around it is populated with dragonflies and dragonfly larvae. This is so because of the absence of fish.

It was then noted that the dragon lies fed of the insect pollinators such as the bees and butterflies. Since these dragonflies and its larvae are abundant in the field which is close to the pond with no fish, they will grossly depend on the insect pollinators as their source of food thereby decreasing the rate of pollination in the field next to the pond with no fish.
