4.Answer: There are more molecules in a gram of water.
Explanation: Specific heat is the heat required by 1 gram of a substance to raise its temperature by .
As the specific heat of water (4.186 J/g°C) is more than that of ethanol (2.450 J/g°C) it means more energy is required to raise the temperature of a gram of water by 1°C. Which means the molecules are tightly bound and thus more molecules are contained in a gram of water.
Q= heat gained
m= mass of the substance
c = heat capacity

Answer:
Freshwater
Explanation:
Protonephridia are made up of many flame cells. Flame cells are specialized excretory cell found in the simplest freshwater invertebrates like flatworms.
Answer:
Strawberries and raspberries aren't really berries in the botanical sense. They are derived from a single flower with more than one ovary, making them an aggregate fruit. True berries are simple fruits stemming from one flower with one ovary and typically have several seeds.
Answer:
This structure provides support and protection for plant cells = Cell Wall
This is a large, central fluid-filled structure that provides turgidity = Vacuole
A thin semipermeable barrier around the cell which regulates what enters and leaves the cell = Cell membrane
The control center of the cell = Nucleus
It is often described as the cells Power Plant = Mitochondria
This is used by plant cells for photosynthesis = Chloroplast
Hope this helps :)
Plz mark Brainliest :D
Explanation:
The giant blue thing is the vacuole
The thin yellow line is the cell membrane
The yellow and orange ball is the nucleus
The light green thing with zig zag lines is the mitochondria
The dark green thing inside the cell is the chloroplast
The thing outside the cell is the cell wall its green
