]To calculate the amount of heat entering or leaving a system, the equation
Q
=
m
c
Δ
T
is used.
Explanation:
m = mass (in grams)
c = specific heat capacity (J/g°C)
ΔT = change in temperature (°C)
Here, we will use the specific heat capacity for liquid water which is 4.19 J/g°C.
The mass given is 25.0 grams.
As for the change in temperature, I will assume that it start off at room temperature, 25°C.

Answer:
Karyotype is a test to identify and evaluate the size, shape, and number of chromosomes in a sample of body cells. Extra or missing chromosomes, or abnormal positions of chromosome pieces, can cause problems with a person's growth, development, and body functions.
Explanation:
this is copied so be careful hope it helps
The fish moves up the river to spawn, a walrus stays warm in the cold ocean are the results of an organism having lipid in its body.
Explanation:
The fish have energy deposited in the form of fat or lipids, they do not feed during spawning and gets energy from the fats.
A walrus has good insulation of fat layer over their bodies as they live in the arctic region. The thick layer of lipid/ fat helps it to survive in freezing temperatures.
Plant cells obtain their energy by making their own food through the process of photosynthesis. Photosynthesis is a process by which carbon dioxide , water and light energy are utilized by plants to make energy-rich carbohydrates such as glucose. Plants store up the glucose as starch in their tissues. When plant cells needs energy, they simply take glucose molecules from their store of starch and use it in cellular respiration to produce ATP, the form of energy that the cell uses to function.
Animals on the other hand do not make their own food but ingest ready made food and break it down into its simplest units through the process of digestion. Complex carbohydrates are broken down to glucose units. Glucose is directly taken in by the animal cells where it is used in cellular respiration to produce ATP ,which fuels the cell activities.
