Across:
10. The circulatory system transfers nutrients, gases, liquids, and heat around the body.
11. The circulatory system transports heat, which helps regulate temperature.
13. The place where oxygen enters the blood and carbon dioxide leaves the blood. Lungs.
15. A gas that is transported in arteries from the lungs to the rest of the body via the heart. Oxygen.
Down:
2. The heart, blood, and vessels. Circulatory System.
4. Blood in arteries is bright red because it is rich in oxygen.
6. A waste gas that is transported in veins from the body to the lungs via the heart. Carbon di Oxide.
<u>Explanation:</u>
The circulatory system includes blood vessels, blood, and heart. This system provides the body tissues with oxygen and some nutrients. It also carries hormones and eliminates needless waste products.
This transportation takes place between the cells via blood throughout the body. The channel that blood passes through is a blood vessel that is pumped by an organ called heart. The heart directs the blood passing all over the body.
The lungs are a duo of air-filled, spongy organs positioned on both sides of a human's chest. Its main function is to take in air present in the atmosphere and transfer oxygen to the bloodstream. From where it gets circulated throughout the body.
Answer:
Sue was not right as wood is not a heat conductor and will not allow heat to pass through the spoon thus keeping the hand safe. In a meatal spoon, heat can pass through and burn the hand as meatal is a good conductor of heat.
Answer:
48 volts
Explanation:
Voltage (E) = Current (I) x Resistance (R), or E = IR.
Answer:
Oceanic trenches
Explanation:
Oceanic Trenches are hemispheric-scale long but narrow topographic depressions of the sea floor
Answer:
Corresponds to a covalent compound.
Explanation:
Both Boron and Fluorine are nonmetals, forming a covalent bond, the result of which is the boron trifluoride compound (BF3). This is a highly toxic gas.
It is synthesized by the reaction between hydrogen fluoride and boron oxide:
B2O3 + 6 HF → 2 BF3 + 3 H2O
