density is mass over volume
find the mass of the water and then divide it by the volume (25)
The density of heavy water at 20 degrees Celsius can be calculated as the mass of the water divided by its volume, which in this case is 1.105 g/ml.
To determine the density of the heavywater, we need to consider the mass of the water and the volume it occupies. The mass of the water can be calculated by subtracting the mass of the beaker from the final mass. That is 64.859 g (final mass) - 37.234 g (beaker mass) = 27.625 g (mass of water). The volume of the water is given as 25.00 ml. Since the density of a substance is defined as its mass per unit volume, we can calculate the density as mass / volume = 27.625 g / 25.00 ml = 1.105 g/ml. Therefore, the density of the heavy water at 20 degrees Celsius is 1.105 g/ml.

the cell theory states that all new cells come from other living cells, and it's true for both multicellular as well as unicellular organisms.unicellular organisms reproduce through asexual reproduction,There are different types of reproduction like binary fission, vegetative, budding, fragmentation etc reproduction in unicellular organisms, through that they directly divide into new similar cells.
whiltin multicellular organisms, reproduction takes place through sexual reproduction, where male and female gametes are formed in separate reproductive organs and get transferred to form an embryo.
so in nut cell in unicellular organisms there is no specific organs,that is responsible for reproduction, while in multicellular there coplex reproductive system
a.gases
b.solids and liquids
c.liquids and gases
d.liquids
the answer is D
brainly is stubborn and wont let me put the answer so ignore this because I have to add at least 20 letters :)
Question 1 is true because it was called Pangea
Question 2 is false because it had a lot of impact on the distribution of species, before the moving continents animals could roam where ever they want but after the splitting of the continents the species were stuck in one place because water separated other continents and land species cant swim.
b.) Decreases
c.) Remains the same
d.) Volume changes
Temperature is the average kinetic energy so I would say the answer is A.
