Ans.
Nitrogen fertilizers are commonly used by farmers to increase crop production. Ammonium is the main component of nitrogen fertilizer, as it is easily assimilated by plants and provides nitrogen to them, while nitrate gets easily lost from the soil. During nitrogen cycle, ammonium is converted into nitrate by nitrification. So, nitrification inhibitors are used with to slow down the conversion of ammonium to nitrate to provide nitrogen for longer time.
Thus, 'to increase crop production, nitrification step of nitrogen cycle is preferred by farmers to block, or slow down.'
Throwing waste in to water, or spilling anything in the water that's not supposed to be in the water
The answers are "water and mineral ions" and "amino acids and sucrose" respectively.
For the xylem, it usually transports water and mineral ions that are absorbed from the root hair cells up to the leaves, where photosynthesis take place. Water is one of the necessary substance for photosynthesis to take place, while different mineral ions can help the plant by for example Magnesium ions can help produce chloroplast.
While phloem transports amino acid and sucrose from the location of production (eg. Leaves by photosynthesis) to the place where it is used or stored. Plant needs these substances to generate energy for activities such as growth by for example cellular respiration. This process is called translocation.
Both of these tubes help transport substances in the plant, in order to keep the plant alive.
The individuals make up the population, like the basic unit of measurement for a group of animals/living things.
Explanation:
The biosphere, (from Greek bios = life, sphaira, sphere) is the band of the planet Earth anywhere life lives. The biosphere is one of the four layers that comprise the Earth along with the lithosphere (rock), hydrosphere (water) and atmosphere (air) and it is the amount of all the ecosystems.The levels of biological structure from individual to biosphere are, subatomic particles, Atoms, Small Molecules, Macromolecules, Molecular devices organelle cell tissue organ system organism population species agreement ecosystem and Biosphere.
Answer:
1. Pigs, Sheep, Goats, Cattle
2. The purpose of rearing pigs is to utilize them for human food but also supply skin, fat and other materials for use as clothing or leather, ingredients for processed foods, cosmetics, and medical use.
3. <em>Breeding</em> - when animals mate and then produce offspring.
<em>Species</em> - Organisms that have lots of characteristics in common, and can mate to produce fertile offspring.
<em>Herd</em> - a social group of certain animals of the same species, either wild or domestic.
Explanation:
4. Bovine - Cattle, Goats, Pigs
Ovine - Sheep
Equine - Horses and other members of the horse family
