Answer:
The three parts of an amino acid are the carboxyl group, the amino group, and the central carbon that contains the R group.
Explanation:
Trophic pyramid, also called an energy pyramid, showing the progression of food energy. The pyramid base contains producers, organisms that make their own food from inorganic substances. ... Thus, the higher the trophic level on the pyramid, the lower the amount of available energy.
Answer: The correct option is E ( Intermediate filaments are unpolarized).
Explanation:
Intermediate Filaments are usually associated with cells that can withstand mechanical stress which includes claws of animals, hair and makes up the dead remnants of the epidermal cell of the skin. Therefore without the supporting network of intermediate filaments, an epithelium remains intact but the cells are prone to damage by abrasive forces.
Intermediate filaments are so named because they are thicker than actin filaments and thinner than microtubules or muscle myosin filaments
The properties or characteristics of an intermediate filaments that explains the lack of motor proteins is as a result of its subunits which are elongated, not globular and are associated in an anti-polar manner. Therefore, the overall filament has no polarity, and therefore no motor proteins move along intermediate filaments
Answer:
1. Apoplastic
2. Symplastic
3. Symplastic
4. Apoplastic
Explanation:
The interconnected porous cell walls of plant cells make apoplast along which water is allowed to move freely. Symplast refers to the path made up of interconnected cytoplasm of many plant cells connected by plasmodesmata. Therefore, water and dissolved minerals enter the root cortex from the epidermis in the solution can move through symplast and apoplast till endodermis.
Water and dissolved minerals present in the cytoplasm of cortical cells move from one cell to next via plasmodesmata (the symplast) while the ones present in their cell walls and intercellular space move through apoplast. The presence of casparian strips in the endodermal cell wall does not allow the movement of water and minerals through the apoplast.
