Answer: Valves in the veins
Explanation: The flow of the blood inside the body takes place through the veins and arteries. The oxygenated blood from the heart is supplied to the different parts of the body.
The blood flows from the capillaries to the venules and from there to the veins. The blood moves in the veins by the rhythmic movement of the smooth muscles in the body.
Most of the blood moves against the gravity so there is a chance that it can backflow so to prevent this there are valves in the veins known as one way valves.
Answer:
(a)-Kinesthetic
Explanation:
- The <em>Vestibular sense </em>is responsible for our sense of spatial orientation or balance.
- The Auditory sense is responsible for the perception of sounds.
- The Umami Olfactory sense is responsible for our sense of smell and taste.
So the answer is (a), kinesthesic. It is thanks to the kinesthetic sense that we can go up stairs easily without stopping to see and carefully control the movement of each of our legs.
A gene is a section of DNA that codes for a trait or other functional product so the answer is B. gene :)))
