Yes ples omggggggggg

The answer is A.

Explanation:

They both work together to circulate oxygen and blood throughout the body.

pressure at depth 1 m is 3.098 ×  N/m²

Explanation:

given data

depth = 3 m

air pressure = 3 × N/m²

to find out

pressure at depth 1  m

solution

we know air pressure is 3 × N/m²  so at pressure 1 m will be

pressure = air pressure + water pressure at 1 m    ............1

water pressure at 1 m is = ρ × g × h  

water pressure = 1000 × 9.8 × 1  

water pressure = 9800

so from equation 1

pressure = air pressure + water pressure at 1 m

pressure =  3 ×  + 9800

pressure = 3.098 ×

so pressure at depth 1 m is 3.098 ×  N/m²
