This is an ecosystem energy pyramid that illustrates how much energy is found at each trophic level of a food chain. Select all the statements about this pyramid that are TRUE.
Approximately 90% of energy from one trophic level is transferred to the next trophic level.
Looking at the total amount of energy in an ecosystem, most energy can be found in the primary consumers.
This energy pyramid explains why there are few tertiary consumers in most ecosystems.
Looking at the total amount of energy in an ecosystem, most energy can be found in the producers.
While both carbohydrates and lipids are made up of carbon, hydrogen and oxygen there are several differences:
1. Carbohydrates are chains of 2 or more carbon atoms. These can be very lengthy (like long cellulose chains of glucose units). They have many polar OH groups (e.g. glucose - C6H6O6). Most carbohydrates are hydrophilic and are soluble in water because of their polar OH groups. They are not necessarily sugars nor are they necessarily sweet. They are also important components of DNA, RNA and ATP.
2. Lipids are more diverse in their chemistry. They generally have a polar region at one end (this end attracts water) and a large non polar hydrocarbon region that repels water. Lipids don't dissolve in water and instead clump together with their hydrocarbon regions on the interior. Lipids include oils, fatty acids, waxes, steroids and hormones.
Make a paraffin block with that wing present inside. Now make fine slices of that block. Take one fine & even slice on a slide & then stain it.
Hope this helps you!
Answer:
Astrocytes
Explanation:
Astrocytes are the most abundant cells in the central nervous system that twine around nerve cells supporting the brain and spinal cord. They perform many functions; such as providing the nuerons with nutrients, control the blood brain barrrier and blood flow. Astrocytes are basically responsible for maintaining the central nervous system homeostasis.
