]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.

The answer would be true
The objective of vaccination is to elicit the primary immune response by introducing pathogen antigens. This antigen can be a whole weakened pathogen or just part of pathogen proteins.
The antigen will activate the primary immune response cascade that <span>will </span>activate of B-cells and T-cells from the secondary immune response. This will makes secondary immune response ready when the real pathogen comes.
Answer:composition and atomic arrangement
Explanation:
Because of the vagueness and lack of context of this question, there is no definitive answer anyone can give. Update your question to provide multiple choices or context for an accurate explanation.
I believe that the answer would have something to do with either, Habitats are being destroyed faster than the plants can be discovered or <span>The plants’ habitats are so remote that they cannot be reached.</span>
