1. Atrium

2. Ventricle

3.left ventricle

4. they pump blood throughout the body

5.superior vena cava

6. Pulmonary vein

7.Four heart valves control the flow of blood through the heart. They act as one-way doors, opening to let blood exit or enter a chamber, then closing to keep blood from flowing backward.

Contrast what happens to thermal energy in evaporation and condensation
Alex17521 [72]
Answer - Will try to Answer in simplest form with Reasoning. Since no one responded.

1.Solar-Thermal energy. For example the sun radiates thermal energy aka heat which then turns Liquid aka Water in gas molecules because they are escaping. (Evaporation) 

2. Condensation happens when the water molecule vapor clump together before thermal energy can be separated by it. Such as the clouds which they form tiny vapor/mist. Thats why when your on a plane and when you hit thru that cloud at hundreds of mph. Your hitting water molecules lol.

1.What do other organisms rely on plants for?
Black_prince [1.1K]

Answer: Organisms depend on other organisms and on the nonliving things in an ecosystem to meet their basic needs for food, water and protection. 3. Plants use energy from the sun to produce their own food from air and water.

A fish maintains its depth in fresh water by adjusting the air content of porous bone or air sacs to make its average density th
Volgvan

Answer:

0.153

Explanation:

We know the up-thrust on the fish, U = weight of water displaced = weight of fish + weight of air in air sacs.

So ρVg = ρ'V'g + ρ'V"g where ρ = density of water = 1 g/cm³, V = volume of water displaced, g = acceleration due to gravity, ρ'= density of fish = 1.18 g/cm³, V' = initial volume of fish, ρ"= density of air = 0.0012 g/cm³ and V" = volume of expanded air sac.

ρVg = ρ'V'g + ρ"V"g

ρV = ρ'V'g + ρ"V"

Its new body volume = volume of water displaced, V = V' + V"

ρ(V' + V") = ρ'V' + ρ"V"

ρV' + ρV" = ρ'V' + ρ"V"

ρV' - ρ"V'  = ρ'V" - ρV"

(ρ - ρ")V'  = (ρ' - ρ)V"

V'/V" = (ρ - ρ")/(ρ' - ρ)

= (1 g/cm³ - 0.0012 g/cm³)/(1.18 g/cm³ - 1 g/cm³)

= (0.9988 g/cm³ ÷ 0.18 g/cm³)

V'/V" = 5.55

Since V = V' + V"

V' = V - V"

(V - V")/V" = 5.55

V/V" - V"/V" = 5.55

V/V" - 1 = 5.55

V/V" = 5.55 + 1

V/V" = 6.55

V"/V = 1/6.55

V"/V = 0.153

So, the fish must inflate its air sacs to 0.153 of its expanded body volume
