Answer:
A. Actin filaments and microtubules
B. intermediate filaments
Explanation:
Actin filaments and microtubules are two major building blocks that form part of the cytoskeleton in all eukaryotic cells. Both actin filaments and microtubules play a fundamental role in the dynamics of the cytoskeleton, and they are involved in many essential cellular processes including, among others, mitosis, cytokinesis, intracellular transport, cell signaling, etc. Moreover, intermediate filaments are very stable structures found in animal cells, where they extend from a ring around the cell nucleus to the plasma membrane in order to provide consistency and shape to the nuclear envelope.
Answer:
Amino acids are the building blocks of life and are encoded by DNA. Enzymes and structural proteins are made of amino acids, and are used as precursors for other important biomolecules in the body. In addition, many different industries ranging from pharmaceuticals to the food industry rely on amino acids.
Darwins <em>theory</em> of <em>evolution</em> explains how modern organisms evolved over long periods of time through descent from common ancestors. <em>Darwin</em> meant that different, yet ecologically similar, animal species inhabited separate, but ecologically similar, habitats around the globe.
Answer:
Hazardous and solid wastes can be solid, liquid and gaseous form.
Explanation:
Hazardous wastes are wastes that are composed of harmful or toxic substances which is generated from industries, households, hospital e.t.c that are threat to humans and their environment.
Solid wastes are discharged or absconded materials such as refuse, sludge, gabbage, from water treatments, air pollution, household, industries e.t.c.
