Answer:
C. ATP is required to move substance A into the cell.
Explanation:
As the model shows a cell with the movement of substances A and B, so the correct statement following the model is "ATP is required to move substance A into the cell".
This is so because ATP is required by a cell to move the substance such as ions across a membrane against a concentration and at the same time another substance moves out of the cell by the process called diffusion.
<u>As in the model, we can see substance A is moving in the cell while B is moving out of the cell (distance between cell membrane and substance B is more).</u>
Hence, the correct answer is "C. ATP is required to move substance A into the cell."
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.
Question
Which of the following terms is most likely to indicate the removal of genetic material?
Answer:
A.) gene splice hope this helps!
Answer:
Baby 1 is the Smith's and baby 2 is the White's
Explanation:
Looking at the table and finding both of the parents blood types, seeing where they intersect at a square you can find what the baby's possible blood types are. Looking at the Smith's, going from both the B blood types you can see that the possible blood types are B or O. The White's blood types are AB and B, looking at the chart you can find the baby's possible blood types are A, B or AB but not O, so baby 1 cannot be their child.
