Answer:
Forest biome: It gives us medicinal plants, woods for commercial purpose. Forests provides us rubber and fibers that is very important for the industries for making various products. They also contribute to perform ecological functions such as carbon storage, nutrient cycling, water and air purification. It also provides habitat to the wildlife.
Freshwater biome: We use fresh water for drinking water, irrigation, sanitation systems, and in industrial factories. Water used from groundwater, rivers and lakes is regained by rain and snowfall.
Marine biome: It serves huge amount of oxygen into the environment and absorbs the atmospheric carbon dioxide.
As a result of the activity of human there is a significant decrease in the number of trees. The products now used are synthetically made which were made up of natural fibers previously. The water source such as rivers, lakes, and ponds are polluted due to which many water borne diseases are increasing day by day. The accumulation of waste which are found in marine biome are reducing the number of flora present inside marine ecosystem.
Answer:
41 cycles
If cell division went 2 cell division cycle beyond the precursor; we have 43 cycles
The volume would be = 17.59 Litres
Explanation:
From the given information:
The number of cells in the liver that developed from an embryonic precursor is roughly 
The number of cell cycles needed to produce 
cells is:
= 
= 40.86
41
Thus, nearly 41 cycles of cell division are required to form the mature liver.
Now;
Suppose 2 extra cell division cycles took place;
The total number of cells would be 2⁴³ = 1.759 × 10¹³; &
The volume would be = 1.759 × 10¹³ × 10⁻¹²
The volume would be = 17.59 Litres
<span>In fixation, the first stage of the Calvin cycle, light-independent reactions are initiated; CO2 is fixed from an inorganic to an organic molecule. In the second stage, ATP and NADPH are used to reduce 3-PGA into G3P; then ATP and NADPH are converted to ADP and NADP +, respectively.</span>
The ecosystem of the forest is formed by the interaction between the abiotic and biotic factors. Abiotic factors are the non-living factors: water, temperature,light,cloud cover, and soil. Biotic factors oh the other hand are the living organisms. Tropical rain forests<span> are hot, moist forests found near Earth's equator.</span>
Temperate rain forests are cool and dry.
Abiotic factors in temperate rain forest:
1. Temperature:The climate in the temperate rain forests is mild.
2. Water: moist and lush.
3. Light: many clouds block the sunlight.
4. Soil: nutrition rich.
Biotic factors:<span>beavers, raccoons , cougars and black bears. </span>
Abiotic factors in tropical rain forest:
1. Temperature: hot, near the Earth's equator
2. Water:60
to 160 inches of precipitation
Biotic factors: the greatest
biodiversity in the world<span>,
rubber and bamboo trees, sloths, anteaters, poison dart frogs, </span>
It is obvious that the sandstone is older than the granite. This is because the sandstone had to already exist when the granite formed from molten rock, as some of the sandstone was captured within the layer of hardening granite. The geological principle of inclusions supports this conclusion.<span> Inclusions, in this case the sandstone, are always older than the rock they are found in. </span>
