Answer:

every muscle cell of the motor unit is stimulated to contract.

Explanation:

Stimulus in biology can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.

In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ. Therefore, the senses are necessary for behavior because stimuli must be sensed in order to respond.

Stimulus control can be defined as a phenomenon that arises when a living organism responds or behaves in the presence of a stimulus and in another way in the absence of a stimulus.

For example, opening the door of a microwave oven as soon as its timer beeps.

Example II; When your body touches a hot object, you quickly move away and feel some pain subsequently.

Action potentials generates the nerve impulse in a motor neuron.

When an action potential is generated within a motor neuron, every muscle cell of the motor unit is stimulated to contract.

A mite is a tiny organism that may "ride" on top of an insect such as a beetle in order to move quickly from place to place.
Whitepunk [10]

Answer: the beetle is neither harmed nor helped by the mite.

In flies, red eyes (R) are dominant to brown eyes (r). A heterozygous fly is crossed with a homozygous recessive fly
hichkok12 [17]

Answer:

The cross of a heterozygous fly with a homozygous fly can be shown as follows:

         r            r

R      Rr           Rr

r        rr            rr

The results show that there is a 50% probability that the flies produced will have red eyes. Their genotypes will be heterozygous.

The results of the punnet square show that there will be a 50% probability that the offsprings will have brown eyes. Their genotype will be homozygous recessive.

A homozygous trait can be described as a trait which has same alleles for the gene which encodes the trait. Heterozygous means that both the alleles for the trait will be different.
