1.each of several hierarchical levels in an ecosystem, comprising organisms that share the same function in the food chain and the same nutritional relationship to the primary sources of energy.
A scavenger is an organism that mostly consumes decaying biomass, such as meat or rotting plant material. Many scavengers are a type of carnivore, which is an organism that eats meat. While most carnivores hunt and kill their prey, scavengers usually consume animals that have either died of natural causes or been killed by another carnivore.
Scavengers are a part of the food web, a description of which organisms eat which other organisms in the wild. Organisms in the food web are grouped into trophic, or nutritional, levels. There are three trophic levels. Autotrophs, organisms that produce their own food, are the first trophic level. These include plants and algae. Herbivores, or organisms that consume plants and other autotrophs, are the second trophic level. Scavengers, other carnivores, and omnivores, organisms that consume both plants and animals, are the third trophic level.
Nitrogen is converted from atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation. The majority of nitrogen is fixed by bacteria, most of which are symbiotic with plants. Recently fixed ammonia is then converted to biologically useful forms by specialized bacteria.
Answer:
The fate of glucose-6-phosphate,glycolytic intermediates and pentose phosphate pathways are described below
Explanation:
Fate of Glucose -6-phosphate
Glucose-6-phosphate undergo dephosphorylation to form glucose when there is an increase demand of glucose in the body.
Glucose-6-phosphate enters into pentose phosphate pathway to synthesize ribose-5-phosphate which is used during denovo pathway of purine nucleotide biosynthesis.
Fate of glycolytic intermediates
Glyceraldehyde-3-phosphate is an important intermediate of glycolysis.The glyceraldehyde-3-phosphate act as a precursor during lipogenesis that deals with the biosynthesis of triacylglycerol.
Fate of pentose phosphate pathway intermediates
Ribose-5-phosphate and NADPH are the important intermediates of pentone phosphate pathway.
Ribose-5-phosphate act as a substrate molecule during the denovo biosynthesis pathway of purine nucleotides.
NADPH act as a reducing agent during fatty acid biosynthesis process.
The warm air will rise because cold air is heavier than warm air.
<u>The heart is a cone-shaped muscular organ located within the mediastinum of the thorax.</u>
The mediastinum is the space lined with membranous tissue between the lungs. The mediastinum contains not only the heart but also the great vessels (pulmonary artery, aorta, pulmonary veins, and the superior and inferior vena cava), as well as parts of the esophagus and the trachea.
<span><u>Its apex rests on the </u><u>diaphragm</u><u> and its superior margin lies at the level of the </u><u>2nd</u><u> rib.</u>
</span>
The apex of the heart is the conical area created by the confluence of the ventricles, but mainly by the left ventricle. It rests on the diaphragm. The superior margin of the heart, also known as the base, lies at the level of the second rib.
<span><u>Approximately two-thirds of the heart mass is seen to the left of the </u><u>midsternal border</u><span><u>.</u>
</span>
This is because to the left of the midsternal border lies the left ventricle which comprises most of the heart mass as the left ventricle is the one responsible for pumping blood throughout the systemic circulation and significant pressure should be overcame; resulting to the physiologic hypertrophy of the left ventricle.
</span><span><u>The heart is enclosed in a serosal sac called the </u><u>pericardium</u><u>. The loosely fitting double outer layer consists of the outermost fibrous pericardium, lined by the parietal layer of the serous pericardium.</u></span>
The pericardium is one of three layers of the heart (other ones being the myocardium and the endocardium); and is the outer layer of the heart. The pericardium is composed of two tissues, the fibrous pericardium and the serous pericardium. The pericardium functions to lubricate the movement of the heart by the action of the pericardial fluid.
<span><u>The heart has </u><u>four</u><u> chambers. R</u></span><span><u>elative to the roles of these chambers, the </u><u>atria </u><u>are the receiving chambers, </u></span><span><u>whereas the </u><u>ventricles </u><u>are the discharging chambers.</u>
</span>
The four chambers of the heart are namely the right atrium, right ventricle, left atrium, and the left ventricle. Venous blood goes to the right atrium via the vena cavas then to the right ventricle via the tricuspid valve; then to the pulmonary circulation via the pulmonary artery where it will be oxygenated. From the pulmonary circulation, the left atrium will receive the oxygenated blood via the pulmonary veins then to the left ventricle via the mitral valve where it will be pumped to the systemic circulation via the aorta.
Yes your equation is correct as formula for butane is c4h10 and equation is balanced
