The answer is dormancy

Right away we can tell that dispersal is not the answer. It simply refers to how plant seeds are spread around.

That leaves us with fertilization, germination, and dormancy.
Fertilization refers to the union of the male and female reproductive cells which form a fertilized egg. However, the embryo is not alive at this point yet, so we can move on to the next answer choices.

Germination, this is the actual growth of a seedling from the seed. We are looking for a period in which is not growing so by its very definition, germination cannot be the answer.

Lastly, we have dormancy.

Dormancy is a period in which the embryo is dormant. Think about a dormant volcano. There is magma within the volcano, and it is considered "alive" but it does not erupt. Similarly, a dormant embryo of a seed is one that is alive but simply isn't growing. This typically happens during winter. Almost as if it undergoes hibernation.

In which type of cells would you find a permanent (Sap)vacuole: a plant or a animal cell

3241004551 [841]

Answer:

The answer is plant cells they would be the type of cells you would find a permanent. an animal cell would not have that.

Explanation:

The reason plant is the answer is because plant cells contain a cell wall made of cellulose to strengthen the cell. They also have a permanent vacuole which is filled with cell sap to help keep the cell turgid.

The reason why animal cells don't have a permanent is because Animal cells may have more than one vacuole, and they are smaller than a plant cell's. Vacuoles are used to store materials in the cell that may be used by the cell or wastes that must be moved out of the cell.

When an action potential is generated within a motor neuron, ________. When an action potential is generated within a motor neur

svlad2 [7]

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.
