Answer: the correct option is A ( The spotted coat is an INHERITED TRAIT, and the ability to perform tricks is a LEARNED TRAIT.
Explanation:
Dog is one of the first domesticated animal by man because it has the ability to perceive information and retain it as knowledge for applying to solve problems.
Therefore, the ability to perform tricks is a LEARNED TRAIT. This is so because they have acquired the ability to understand and communicate with humans, and they are uniquely attuned to human behaviors.
INHERITED TRAIT is a trait that can be passed down from one generation to another which are found in genes within the strands of dogs DNA. Some of the inheritable traits includes the following:
- coat color,
- ear type, and.
- tail style.
Therefore the spotted coat is an INHERITED TRAIT
Answer:
1.67×10^25 molecules
Explanation:
No of molecules = no of moles × Avogadros number
No of moles= mass in gram / molar mass
No of moles of water in given sample = 500.3/18
= 27.79 moles
No of molecules = 27.79× 6.02×10^ 23
= 167.32×10^23 or 1.67×10^25
The change directly from solid to gas is called sublimation
The red blood cell will shrink.
In salt solution, the water potential is a lot lower than the cell cytoplasm. In that way, water molecules will flow from the inside of the cell to the salt solution by osmosis. The red blood cell will loose so much water that it shrinks.
But we don't have to worry about that because this won't occur inside our body, since there is mechanism in our body that regulates the concentration of blood.
