Answer:
The comparatively fast evolution of various species from a single common ancestor is known as adaptive radiation. It usually takes place when an organism enters a novel region and distinct traits influence its survival. The island chain offers suitable conditions for adaptive radiation to take place as when an organism of a certain species comes to an island together and get disperse all through the chain, and each of these organisms getting settle into distinct niches and exploiting various food resources in order to minimize the competition, thus, resulting into adaptive radiation.
Answer:
dimerization and phosphorylation
Explanation:
Protein kinase receptors are simply saying receptors with associated kinases (usually tyrosine kinases).
Protein kinases are enzymes that have the ability to modulate other enzymes (or some other proteins) by adding the phosphate group. This is known as phosphorilation process. As a result of structural change, protein can change its activity (phosphorilation usually increase the activity).
Such receptors are involved in a many processes within an organism that are important for the cellular growth, differentiation, metabolism .
1. Define Chemosynthesis?
the synthesis of organic compounds by bacteria or other living organisms using energy derived from reactions involving inorganic chemicals, typically in the absence of sunlight.
2. List some organisms that undergo Chemosynthesis?
Chemoautotrophs, organisms that obtain carbon from carbon dioxide through chemosynthesis, are phylogenetically diverse, but also groups that include conspicuous or biogeochemically-important taxa include the sulfur-oxidizing gamma and epsilon proteobacteria, the Aquificae, the methanogenic archaea and the neutrophilic.
3. Which organisms conduct photosynthesis?
Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.
4. Define photosynthesis
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
5. Type out the chemical equation of photosynthesis?
The photosynthesis equation is as follows: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.
Answer:
The correct answer is : D. isoelectric line.
Explanation:
ECG interpretation requires the analysis of various waves and curves and their characteristic. There are different type of waves and curves that can be found and analyzed in ECG such as P- wave, T wave, PR interval and others.
All these curves and interval shows electrical activities generating by the repolarization and depolarization of atria and ventricles of heart.
Base line or isoelectric line shows a flat line which have no electric activity as there is no negative or positive charge to create deflection.
Thus, the correct answer is : D. isoelectric line.
