The correct answer is: A. minus end; dynein
Microtubules are cytoskeletal fibers that have an important role in the intracellular transport (movement of vesicles within the cell) and in the mitotic spindle during mitosis. The plus end of the microtubules extend through the periphery of the cells while the minus ends are anchored within the centrosome.
Necessary proteins for the vesicle’s movement are motor proteins:
• kinesin which is positive end directed
• dynein which is negative end directed
So, beside vesicles these proteins are also involved in organelles’ transport in opposite directions through the cytoplasm.
Answer:
D
Explanation:
Not sure but the sentence is super understamdable
Answer: Chloroplast, endoplasmic reticulum,lysosomes, nucleus, vacuoles.
Explanation:
The cytoplasm can be defined as the fluid that is found inside the cell. This liquid contains various types of salts and minerals dissolved in it.
All the organelles inside the cell is found in the cytoplasm. The organelles like nucleus, chloroplast, vacuoles, lysosomes and other organelles are found in the cytoplasm.
The cytoplasm provides stability, flexibility to the cell. Being the liquid part of the cell it prevents the cell from drying.
Answer:
Soil pollution- Soil pollution is defined as the presence of toxic chemicals in soil
it could pose a threat to humans, etc...
caused by the presence of xenobiotic chemicals
(A xenobiotic is a chemical substance found within an organism that is not naturally produced or expected to be present within the organism.)
or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste.
Air pollution- Air pollution is a mixture of solid particles and gases in the air.
Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles.
