Explanation:
Logically, the cell would have two nuclei because karyokinesis (the division of the nucleus) occurs before cytokinesis (division of the cytoplasm).
The correct answer is the one that shows a bone having the most porous appearance inside.
Osteoporosis is a disease of the different types of bone tissue that make up bone ("cortical bone" and "trabecular bone").
It is a disease that is related to a decrease in the amount of bone tissue in the bones and / or an alteration of its structure: thinning of the cortex and bone trabeculae that become porous.
The cause is an imbalance between the deficit activity of osteoblasts and normal osteoclastic bone resorption.

Answer:
the thin filaments are pulled away from one another, thereby reducing their ability to interact with myosin
Explanation:
The myofibril is the basic unit of a muscle cell. Each myofibril is composed of contractile units known as sarcomeres which may contain two different types of myofilaments: thick myofilaments and thin myofilaments. The thick filaments are known to have a constant length, and they consist especially of myosin proteins. These filaments (thick) do not extend to the ends. On the other hand, the thin filaments extend in from each end, and they are mainly composed of actin proteins that serve as tracks for the movement of myosin proteins.
