Answer:
11 electrons are found in a neutral atom of sodium.
Explanation:
atoms are made up electrons and protons. Electrons are negatively charged particles and protons are positively charged particles. The number of electrons and protons are constant or fixed in an element. However, the number of electrons and protons may not be always equal. the number of protons in the atom is equal to the atomic number of the element. sodium's atomic number is 11 and thus the number of protons is also equal to 11. since sodium atom is neutral, the number of protons = the number of electrons. thus the number of electrons in a neutral sodium atom is 11
Europe is the most likely answer.
<span>The digestive system contains
various enzymes that can help in the proper digestion of food, and we all know
that digestive system starts from the mouth. But the human digestion is
different than that of the cow. Cows have slight difficulty to digest food than
humans because of cellulose found in hay and grass. Good thing that there are
billions of bacteria and organisms that live and die in the rumen (biggest of
the four stomachs) of the cow. These organisms they break down food and
efficiently convert them to nutrient the cow needs in order to prevent
starvation.</span>
Given: The population density of frogs in a portion of a pond is 12 frogs per square meter. The size of the entire pond is 370 square meters.
To find: The total population size of the frogs in the pond.
Method: Using unitary method of proportions
Solution:
Let p be the density of the frogs present per square meter.
Let A denote the total area of the pond.
∴ p = 12 frogs/m² and A = 370 m²
The total number of frogs in the pond is given by,
Therefore, there are 4440 frogs in the pond.
D) being drought resistant.
