Chromosomes condense during prophase
Answer:
The correct answer is E. Arachidonic acid is the raw material for synthesis of eicosanoids.
Explanation:
Arachidonic acid is an essential omega-6 fatty acid formed by a 20-carbon chain with four double bonds. The presence of double bonds causes this molecule to have several sites that can be oxidized, allowing the formation of different lipids with different biological activities.
Arachidonic acid is part of phospholipids in cell membranes, and is the precursor of eicosanoid biosynthesis. Arachidonic acid can be synthesized from linoleic acid, one of the essential fatty acids required by most mammals.
Answer:
The moon is earths only permanent natural satellite
the moon always shows earth the same face
the sun and moon are not the exact size
the moon is 238,900 miles from earth
the moon is estimated to be about 4.6 billion years old
1. An example of secondary consumer is snake. Secondary consumers are the ones who eat the primary consumers, which makes them carnivore.
2. Photosynthesis is a process used by plants and (some other organisms) that converts water (H2O) and carbon dioxide (CO2) with the presence of sun energy (collected in the chloroplasts) into chemical energy that is later stored in sugars (carbohydrates). Organisms that do the photosynthesis are called autotrophs (produce food by themselves).
3. The energy pyramid represents energy flow in a community, where the different levels represent different groups of organisms.
The food chain is a circulation of energy that comes from the sun and passes from the producer organisms to the primary consumer, secondary and tertiary consumer organisms.
4. For example, plant is producer that is eaten by primary consumer-herbivore (e.g. bugs). Than secondary consumer-carnivore (e.g. snake) eat that herbivore and than is being eaten by tertiary consumer (apex predator that have no natural predator).
5. One trophic level gets only 10% of the energy of the previous level. So, if the plant have 10.000 units of energy and is eaten by rabbit, rabbit gets 1000 units of energy, and when the fox eats an rabbit, it gets 100 units of energy.
6. Trophic level is the position of an organism in the food chain.
