Answer:
u have to find the circumference diameter and radius of the two balls
Explanation:
Answer:
The best explanation was provided by the student Tara who said: "Through photosynthesis, the CO2 and water are changed into new substance, glucose, therefore it is considered a chemical change".
Explanation:
A chemical change is one which is not easily reversible and which results in the formation of new subsatances.
For example, in photosynthesis,a new substance, glucose is formed from the original substansubstances, carbon dioxide and water. Also, the reverse process of the formation of carbon dioxide and water from glucose is not easily obtained in plants.
From explanations provided by the students :
Luke does not give any explanation of the process but only an observation
Jackie's explanation does not state the main reason why a chemical change differs from a physical one.
Tara, gives the best explanation as the reason why a change that occcured is a chemical change is clearly stated.
Skyler does not state the main reason why photosynthesismis a chemical change as well, because even physical changes like evaporation of water involves solar energy.
<span>Groundwater
Groundwater flows through rock with a high porosity and a high permeability at a fast rate. The denser and less permeable the rock is, the slower the groundwater moves. The greater the permeability of a rock, the faster the groundwater flows through it. Groundwater is water that is found in spaces and fractures in rocks, as well as in the sediment between the earth's surface. </span>
A MOTILE EUKARYOTE
According to the question, the new organism has:
1. A plasma membrane which is found in all living cells except viruses and prions.
2. Two flagella show that the organism is motile.
3. Peroxisome is a membrane bound cell organelle found in eukaryotic cell.
Answer:
The neuromuscular junction is a connection between a neuron and a muscle fiber.
Explanation:
The neuromuscular junction is formed by the connection between the axon terminal of a neuron and a muscle fiber. This union forms a bridge between the terminal button of a neuron and the muscle fiber membrane, through it the terminals of the neuron are connected with the motor terminal plates, just where the nerve impulses are received. This allows the contraction of muscle fiber, with acetylcholine being the neurotransmitter of muscle stimulation.
