Binocular helps to make distant objects appear nearer and larger
Answer:
In cells use oxygen to release energy stored in sugars such as glucose. In fact, most of the energy used by the cells in your body is provided by cellular respiration.
Explanation:
Answer:
The answer is D
Number of motor units recruited
Explanation:
The force a muscle generates is dependent on the length of the muscle and its velocity which is shortened.
A motor unit is the grouping of muscle fibers supplying nerves by the neuron and consists of the motor neuron.
The number of muscle fibers within a motor unit varies, and is a function of the muscle’s ability for accurate and refined motion.
Precision can be determined to be inversely proportional to the size of the motor unit. As a result, small motor units can exercise greater precision of movement compared to larger motor units. For example, thigh muscles which are responsible for large powerful movements, can have a thousand fibers in each unit, while eye muscles which requires small precise movements, might only have about ten.
Groups of motor units are supplied with nerves to coordinate contraction of a whole muscle and generate appropriate movement; all of the motor units within a muscle are referred to as a motor pool.
As a result, the number of motor units with are recruited will facilitate the maximum amount of tension that allows the student keep his arm extended in place under the increasing weight of the books.
<h2>Answer is option "D"</h2>
Explanation:
- The continuous procedure was single-arrange chemostat development without distribution, henceforth the procedure is persistently taken care of with the development medium and the way of life stock is pulled back at a similar rate so as to keep up the bioreactor volume steady
- Chemostats have for some time been another supported stage for exploratory advancement, and were, truth be told, developed for this application. A chemostat is a development vessel into which a crisp medium is conveyed at a steady rate and cells and spent medium flood at that equivalent rate. In this way, the way of life is compelled to gap to stay aware of the weakening, and the framework exists in a steady-state where information sources coordinate yields
- Hence, the right answer is option D "a chemostat using a low-nutrient medium"
