Answer:
B. Stable ecosystems
Explanation:
The main cause of the biodiversity experienced in rain forests is largely due to the stable ecosystems that they enjoy.
A stable ecosystem is a sustainable one that does not change too much over the course of time.
Most organisms and the diverse life forms are easily nourished by the provisions made available by nature in such regions.
- Most rain forest receives a large amount of solar radiation and energy all year round as the sun is directly overhead here.
- This suggests that the producers have enough energy to cater for their own need and that of the organisms there in.
- The consumers and decomposers have sufficient food available all year round.
- This coupled with other factors whereby organisms have specially adapted to environmental conditions makes a rain forest very biodiverse with life forms.
- An unstable ecosystem cannot be biodiverse
Nails are made of iron because, iron is strong and sturdy; although nail rust when it undergoes oxidation when expose to water but it is not explosive.
Barium and phosphorus are not suitable for nail making because of their properties.
Barium is an element which reacts with virtually all non metals, forming poisonous products which are dangerous to health and to the environment. It also reacts explosively with water.
Phosphorus is not found in its pure form in nature, it conducts electricity and it is combustible in nature.<span />
Explanation:
Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. ... These structures include: chloroplasts, the cell wall, and vacuoles.
Answer:
It is not important for the cell not to run glycolysis and gluconeogenesis at high rate simultaneously because body carry out various metabolic pathaways with respect to body"s requirement for metabolites .
Explanation:
Human bodyphysiology helps to maintain homeostasis of various metabolic intermediates within our body.
It is not that the glycolytic intermediates and end product such as pyruvate always enter the gluconeogenesis process because pyruvate have different metabolic fates beside acting as a precursor for glucose biosynthesis.
Cell does not require glycolytic intermediates and gluconeogenesis intermediates at the same time.
That"s why it is important for the cell not to run glycolysis and gluconeogenesis simultaneously.
