One way that they are economically valuable is that it is mostly made up of the stuff that we have and need now like papers, tables, money, houses, etc. Wood is very very important in the human society and the place to get them is the forests.
A way that it is ecologically valuable is that the trees create habitats for the animals that live in the forests for protection from storms, other animals, etc. The trees in the forest can also be a source of food for some animals because those animal can feed on the leaves.
Answer:
Nutrient cycle is a process of movement, reuse or recycling of nutrients in that particular environment. They are for both living and nonliving things, elements like carbon, oxygen are recycled through such cycles.
Nutrient cycle in an ecosystem involve:
- carbon cycle
- nitrogen cycle
- oxygen cycle
- phosphorus cycle
Answer:
1 H is consumed in exchanging the synthesized ATP in mitochondria with ADP in cytosol by adenine nucleotide translocator (ANT).
Explanation:
The electrons from NADH and FADH2 are transported in electron transport chain through various complexes that act as electron transporter, to oxygen. In this process, the pumping of protons from mitochondrial matrix to intermembrane space causes a concentration gradient and hydrogen ions diffuses out of matrix space through ATP synthase causing the production of ATP.
3 H are enough to pass through ATP synthase for the phosphorylation of ADP to produce ATP. 1 H or 25% of energy yielded from electron transfer is required to exchange the matrix ATP with the ADP in intermembrane space by adenine nucleotide translocator (ANT). This process provides continuous supply of ADP to mitochodaria and ATP which is exported to cytosol is utilized by cell to perform various functions. There will be no ATP production in mitochondria without ADP. So 4 H are required for 1 ATP production.
1 H for importing ADP to mtichodaria + 3 H for phosphorylation of ADP to ATP
Answer:
Osmosis helps cells maintain homeostasis because a cell needs to maintain a specific water balance so that chemical reactions can take place. Osmosis can also be used to balance out the concentration of other molecules (such as sugar or salt) present on either side of a cell membrane.
Explanation:
Homeostasis is the ability of a system to regulate its internal environment through maintaining a stable, relatively constant set of properties such as temperature and PH. Key Terms homeostasis : The ability of a system or living organism to adjust its internal environment to maintain a stable equilibrium, such as the ability of warm-blooded.
Hope this helps.
