Enzymes are usually very specific as to which reactions they catalyze and the substrates that are involved in these reactions. The enzyme and the substrate possess specific complementary geometric shapes that fit exactly into one another. This is often referred to as "the lock and key" model.
Red-flowered snapdragon have a homozygous genotype rr (both alleles are the same)
White-flowered snapdragon have a homozygous genotype r'r'
Gamet for the red-flowered snapdragon is r
Gamet for the white-flowered snapdragon is r'.
<span>F1 generation will have all heterozygous genotypes rr’.</span>
Answer:
<em>“Eutrophication is an enrichment of water by nutrient salts that causes structural changes to the ecosystem such as: increased production of algae and aquatic plants, depletion of fish species, general deterioration of water quality and other effects that reduce and preclude use”.</em>
Explanation:
<em>Hey mate... Here's your answer...</em>
Five layers of the atmosphere are troposphere, stratosphere, mesosphere, thermosphere and exosphere.
<u>Explanation:</u>
Troposphere is the lowermost layer of the atmosphere which is found in the 0-12 km range. The temperature of the troposphere ranges from 15°C to 51°C. Aircrafts driven by propellers can access the troposphere only.
Stratosphere is the layer of atmosphere that is second from earth. It is found in the 12-50 km range. Its temperature ranges from -51°C to-15°C. Jet-powered aircraft can access the stratosphere.
Mesosphere is the third atmospheric layer. It is found in the 50-85 km range. Its temperature ranges from -15°C to-120°C. rockets and rocket-powered spacecraft can access the mesosphere.
Thermosphere is the fourth atmospheric layer. It is found in the 500-100 km range. Its temperature ranges to about 2000°C. the International Space Station orbits in the thermosphere.
Exosphere is the topmost atmospheric layer. It extends to 10000 km above earth. Its temperature is greater than 2000°C. most of the satellites that orbit the earth are found in the exosphere.
The density of atmospheric layers decreases while moving up along the layers. Thus troposphere has the maximum density.
Nocardia is important in bioremediation process because they can decompose polycyclic aromatic hydrocarbons, polychlorinated biphenyls, chlorophenols, sulfonated azo dyes and alkanes.
<h3>What is bioremediation?</h3>
Bioremediation is the process of using living organisms such as microorganisms to degrade wastes in the environment in order to return it to its previous healthy state.
An example of a microorganism used in bioremediation is Nocardia spp.
Nocardia is important in bioremediation because they can decompose polycyclic aromatic hydrocarbons, polychlorinated biphenyls, chlorophenols, sulfonated azo dyes and alkanes.
Based on the complete question which is given as follows:
"Nocardia are of particular interest to scientists for the process of bioremediation because they can degrade _________. (Check all that apply) A. petroleum Hydrocarbons B. rence benzone C. pectin Keratin D. Decode Chiron", the correct options are A and B.
