They have different specifications eg. a muscle cell has lots of mitochondria as it needs to do a lot of work, or a neuron has to have a mylin sheath to insulate signals
Answer:
11,460 years
Explanation:
The age of the bone would be approximately <u>11,460 years</u>.
The half-life of a substance represents the time required for one-half of an amount of that substance to decay or disintegrate.
<em>The half-life of C-14 is approximately 5,730 years. If the ancient bone had decayed for 2 half-lives it means that the bone had decayed for 5,730 x 2 = 11,460 years.</em>
When sarcomeres shorten, the muscle fiber SHORTENS.
Mechanism :
Sacromeres are used to construct the myofibrils, which are a part of the skeletal muscles of animals. They use the sliding filament model to carry out the muscle contraction and relaxation.
To create movement, The cross-bridge between actin and the myosin heads causes the sacromere to shorten. Muscle fibers contract as a result of this shortening of the sacromere, which has the overall effect of shortening the fibers.

Answer:
ans is 8..
Explanation:
We know cube has 6 sides..
Then we get that ..
Volume of a cube is s³..
=> side =2cm
=> V = 2³
= 8
To keep ammonia concentrations at safe and low levels it is transported to the liver where it is transformed into urea and glutamine. Urea is carried to the kidneys and excreted in the urine.
<h3>What is the path of ammonia in the human body?</h3>
Ammonia is a substance produced by intestinal bacteria and body cells during protein digestion. It is a waste product that is normally transported to the liver, where it is transformed into urea and glutamine. Urea is carried to the kidneys and excreted in the urine.
With this information, we can conclude that to keep ammonia concentrations at safe and low levels it is transported to the liver where it is transformed into urea and glutamine. Urea is carried to the kidneys and excreted in the urine.
