Which structure has the active sites where the heads of the thick filaments will bind?

Biology

Gre4nikov [31]3 years ago

THE ACTIN has the active site to which the heads of the thick filament will bind.
The muscle is made up of two major protein fibers, which are the actin and the myosin. Muscle contractions occur when myosin and actin slide over each other in a series of repetitive events. The protein actin has a thin structure and is abundant in eukaryotic cells while myosin is a thick filament.

The glenoid cavity is where the Select one: a. clavicle articulates with the scapula. b. clavicle articulates with the sternum.
kati45 [8]

Answer:

The glenoid cavity is where the d. humerus articulates with the scapula.

Explanation:

The scapula is the bone that contains the glenoid cavity. The glenoid cavity is a part of the shoulder. This cavity forms the glenohumeral joint along with the humerus. The Humerus is a long bone of the upper arm, and the scapula articulates with this bone to form a ball and socket joint at the shoulder. These are all bones forming the shoulder girdle and upper extremities.

How many new volumes would each new cell contain whenever a cell splits?
Elenna [48]
The specific volume will be different for various kinds of cells. The safe answer would be that the new cell will pretty much have the same volume as the one that it divided from. This is true for most eukaryotic cells unless other factors like epigenetics or mutations come into place.

One example of moments a cell would increase in volume is during hypertrophy. This simply means that the cell is increasing in size (compared to: hyperplasia -- which is an increase in number of the cells). Hypertrophy is definitely an increase in volume of the cell but this doesn't necessarily translate to cell division (i.e. just because the cell is big now, doesn't mean it will still be big when it divides).

Another moment of increasing volume of the cell and now also related to cell division would be during the two stages in the cell cycle (i.e., G1 and G2 phases). This is the growth phase of the cell preparing to divide. However when mitosis or division happens, the cells will normally end with the same volume as when it started.

This are safe generalizations referring to the human cells. It would help if a more specific kind of cell was given.
