Answer:
Cytoskeletal elements play important roles in cell division. The mitotic spindle apparatus is made of "microtubules" and pulls sister chromatids apart, whereas the contractile ring is made of "actin filaments" and required for the separation of daughter cells at the end of the mitotic phase of the cell cycle.
Explanation:
The three chief organizational apparatuses of the cytoskeleton are microtubules (formed by tubulins), microfilaments (formed by actins) and intermediate filaments. All three apparatuses cooperate with each other non-covalently. The cytoskeleton is composed of protein filaments and is found throughout the inside of a eukaryotic cell. The cytosol is the main component of the cytoplasm, the fluid that fills the inside of the cell. The cytoplasm is everything in the cell except for the cytoskeleton and membrane-bound organelles.
Answer:
transform
Explanation:
Most earthquakes occur at the boundaries where the plates meet. In fact, the locations of earthquakes and the kinds of ruptures they produce help scientists define the plate boundaries. There are three types of plate boundaries: spreading zones, transform faults, and subduction zones.
Answer:
A. Producer
Explanation:
The primary source of energy for almost every ecosystem on Earth is the sun. Primary producers use energy from the sun to produce their own food
<span>The American Academy of Pediatrics recommends that all </span>babies<span> receive </span>vitamin D<span> supplementation (400 IU per day) due to decreased sunlight exposure and an increase in rickets.
Babies need this due to lack of sunlight exposure and is highly recommended if they're breastfed.</span>
