Answer:
B. Blood in the left ventricle is deoxygenated.
Explanation:
Human heart consists of four chambers namely: right atrium, right ventricle, left atrium and left ventricle. These chambers work hand in hand to perform the function of circulating blood throughout the body.
- The RIGHT ATRIUM receives deoxygenated blood from the heart and passes it to the RIGHT VENTRICLE, which pumps it to the lungs in order to be oxygenated.
- The LEFT ATRIUM receives oxygenated blood from the lungs and passes it to the LEFT VENTRICLE, which pumps it into the body.
- Also, the pulmonary artery carries deoxygenated blood into the lungs for oxygenation while the pulmonary veins carry oxygenated blood from the lungs
Based on the above explanation of the right & left atria and the right & left ventricles, it is FALSE that the blood in the left ventricle is deoxygenated. It is rather oxygenated.
Explanation:
Geese fly together in a v formation.
Geese fly together because when the first goose flaps it's wings it creates an upward force which make it easier for the second goose to fly.
In this way the force increases and the effort the last goose has to spend to fly decreases a lot.
Hope it helps you.

Answer:
B. sarcoplasmic reticulum ; sarcoplasm
Explanation:
A neural signal is the electrical trigger for calcium release from sarcoplasmic reticulum into the sarcoplasm. Electrical signals, called action potentials, travel along the neuron's axon connecting to individual muscle fibers at a neuromuscular junction. Neuron action potentials cause the release of neurotransmitters from the synaptic terminal into the synaptic cleft, where they can diffuse across the synaptic cleft and bind to a receptor molecule on the motor end plate.
