The answer is B. The specific heat means the heat amount the substance needs to absorb when the temperature increases 1℃. The high specific heat means that it needs a huge amount of heat when increase just 1℃. For A, the dissolved salts can help decrease the freezing point.

Answer:
The characteristic that is not a function of the receptors is to receive glucose molecules.
Explanation:
The receptors are structures made up of proteins or glycoproteins whose function is to <u>receive specific signals</u>, which determine intracellular changes and promote an effect or action.
Most of the receptors are located on the surface of the cells, serve for cell recognition and are capable of receiving stimuli from neurotransmitters and hormones.
Glucose is a biomolecule that does not constitute a stimulus or possess a specific receptor and enters the cell with the use of a specific transporter.
Minerals which are good conductors of electricity are described below.
Explanation:
- metals tend to be highly efficient conductors of heat and electricity. The vast majority of elements on the periodic table are metals, and most of these fall into one of five families: alkali metals; alkaline earth metals; the very large transition metals family; and the inner transition metal families, known as the lanthanides and actinides.
- Metals are lustrous or shiny in appearance, and malleable or ductile, meaning that they can be molded into different shapes without breaking. Despite their ductility, metals are extremely durable and have high melting and boiling points. They are excellent conductors of heat and electricity, and tend to form positive ions by losing electrons.
Answer:
D
Explanation:
A and B are wrong because environmental impacts can't change the amount of chromosomes an animal has. D is a better answer than c because genetic variation happens within a population rather than an individual.
