To solve this question you need to know the specific heat of the object, which is water. The specific heat of water is 1 calorie/gram °C = 4.2<span>joule/gram °C. The energy needed would be:
Q= c*</span>m*ΔT
Q= 1 calorie/gram °C * 250 g * (85-25°C )
Q= 15000 calorie= 63000J
the answer is B im pretty sure thats what it iz
Answer:
Meiosis in a parent plant, called a sporophyte, results in the production of spores that are haploid, meaning they have half the genetic information of the parent plant.
Explanation:

Possible environmental contamination.
Explanation:
The best answer is A
Diffusion is said to be the movement of particles, molecules ions from a region where they are more concentrated to a region where they are less concentrated.
Diffusion does not require a semi - permeable membrane and is purely dependent upon the free energy of the diffusing substance only.
Ink particles spread (diffuse) from the drop of ink where they are more concentrated to all the part of the water in the beaker until they are evenly distributed, thus reaching a state of equilibrium.
