lesya [120]3 years ago
6 0

Answer:

a. every muscle has a varying number of motor units so they can generate different frequencies.

e. each motor unit can innervate a different number of muscle fibers.

Explanation:

Electromyography (EMG) is a diagnostic procedure used to measure the response of muscles and nerves to electrical activity. A motor unit is composed of one motor neuron and muscle fibers it innervates. The number of muscle fibers in each motor unit can vary among different muscles and even among motor units within the same muscle. Each motor unit is known to innervate a variable number of muscle fibers, but each single muscle fiber is innervated by only one motor.

Jonathan has type O blood. What must his parents be for Jonathan to get type O blood?
cluponka [151]
Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A.

A student performed an experiment with bags of dialysis tubing filled with distilled water to model the process of osmosis. Dial
Reil [10]

Answer:

Taking into account the principle of osmosis, the question that best addresses experimental design is  <em>How does the effect of environmental sucrose concentrations impact the  movement of water across a membrane?</em>

Explanation:

The experimental design of the student, made with dialysis bags and sucrose at different concentrations should recreate the principle of osmosis, of importance in living beings for organic homeostasis.

Osmosis consists of the movement of water - through a semi-permeable membrane - from a less concentrated solution to a higher concentration solution, following a gradient, to achieve balance.  

The student will observe in his experiment that water moves from the solution with less sucrose concentration to the higher concentration of sugar. Beakers with the highest concentration of sucrose will have the highest weight, due to the increase in liquid volume.

How does the effect of environmental sucrose concentrations impact the  movement of water across a membrane?

The experiment shows that:

  1. The water from the beaker with less sucrose concentration moved -through the dialysis tubes and the membrane- to the beaker containing the most concentrated sucrose.
  2. Different sucrose concentrations will attract different amounts of water, which influences the final weight of each container.

With this experiment the principle of osmosis is confirmed, where the concentration of a solute determines the amount of water that passes through a semipermeable membrane -following a concentration gradient- until equilibrium is reached.

Which flock will be able to eat the most? The least? Why?
pishuonlain [190]

Answer: The omnivorous flock will eat the most as it eats both insects and seeds. With the removal of fruit it will not be affected much. The herbivorous flock will eat the least as it has the option to eat seeds only after the removal of fruit.  The flocks all started with 10 birds. Flock was X the most successful at feeding, so it will have the greatest number in the second generation. brainliest?
