Chemical plant

The four chemicals that are essential for life on Earth are water, carbon, nitrogen and phosphorus. Water is essential for life because it is an excellent solvent. Many different type of material can dissolve in water. Water transport nutrients and waste in and from the human body. Water is also found everywhere on Earth. It can exist as a liquid, solid or gas. Many organisms use water in order to flush toxins anything into and out of a cell. Without water there would be no vegetation on land…

Research has shown that urine helps plants best when diluted with purified water; this is likely due to the fact that urine contains chemicals that would halt (or at the very least, slow down considerably) important processes within the plant. Such processes include, but are certainly not limited to, transpiration and photosynthesis, inarguably the two most vital activities performed within the plant. Transpiration occurs when plants lose water vapor through the guard cells and stomata;…

Identification and characterization of differentially expressed gene(s) in pigeonpea genotypes in response to Helicoverpa armigera infestation Pigeonpea [Cajanus cajan (L.)millspaugh] is an important food legume predominantly cultivated in the tropical and subtropical regions of Asia and Africa almost exclusively as a rainfed crop. It is a diploid (2n = 22), often cross-pollinated crop with a genome size of 833.07 Mbp (Varshney et al., 2012). Globally, it is cultivated on an area of 4.92 M ha…

Plants and animals are interrelated they provide a natural balance in the ecosystem. People also benefit from the wildlife, by providing food, fossil fuels and even as source of income Streams Streams protect against floods by limiting the amount of water…

itself is defined as the ability to do work: All living plants and animals expend energy in their environment. All three laws of thermodynamics apply, especially the first: “Energy can neither be created or destroyed, but merely converted from one form to another”. In any ecosystem, energy is lost to the surroundings. A “Nutrient” is a food or any nourishing substance assimilated by an organism and required for growth, repair, and metabolism. Plants derive nutrients from the physical environment…

Hypothesis 2: Calcium levels in the soil affect species richness. Prediction: An increase in the calcium levels in the soil will decrease the species richness. Reasoning: As the calcium levels increase, some plants begin to take advantage of increased calcium levels and outcompete other plants, driving them to extinction. Thereby, decreasing species richness. Analytical approach: Regression Independent variable: Calcium levels Dependent variable: Species Richness By signing, I acknowledge that I…

as to why the Brazilian pepper tree is a negative entity in Florida. The plant itself bears large clusters of fruit which is frequently sought after by avifauna; when a pepper tree grows near water, its fruits have the chance of falling in and being dispersed (Center for Aquatic and Invasive Plants, n.d.). Consequently, because of the Brazilian pepper tree’s many seeds and avenues for dispersal, it is quite easy for the plant to ‘divide and conquer,’ or, spread and take over ecosystems.…

Explain the chemical properties of nitrates Almost all inorganic nitrate salts are soluble in water at standard temperature and pressure (NOAA). Nitrates are widely used in very large quantities as fertilizers in agriculture because of their readiness to decompose and release nitrogen for plant growth and because of their ready solubility ensuring that nitrate ions can be absorbed by plant root hairs. (NOAA). Nitrate compounds have a wide range of uses which rely on their activity as…

This can occur due to chemicals being taken up faster than it should/can be use, or due to the chemical not being able to be broken down for use by the organism (chemical can’t be metabolised). Bioaccumulation is harmless if the compound that was accumulated is not harmful. Although, compounds such as mercury, can accumulate into living tissues and therefore be dangerous to health. Chemical pollutants that are bioaccumulated come from many sources like pesticides…

The fungi Alternaria is a phyto-pathogen cause leaf blight disease to variety of plants. Alternaria alternata and Alternaria helianthi was isolated from Dalbergia sissoo L. and Helianthus annuus L. respectively. Test antagonists grow faster than the pathogen and produced inhibition zones thereby limiting the growth of the pathogen. These antagonistic interactions influence the incidence and severity of the disease caused by the pathogen. When the two Alternaria spp. were tested by dual culture…
