Explanation:
This energy comes from the food we eat. Our bodies digest the food we eat by mixing it with fluids (acids and enzymes) in the stomach. When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose.
Answer:
A) membrane, nucleus, cytoplasm
Explanation:
- A cell is the fundamental unit of life for living organisms that is made of organelles.
- Each organelle performs a specific function to enhance cell activities.
- Animal and plant cells share certain features and also differ in several ways.
- Animal cells and plant cells contain similar organelles such as cell membranes, mitochondria, nucleus, cytoplasm, and ribosomes among others.
- However, plant cells contain cell wall and chloroplast that are absent in animal cells while animal cells contain centrioles that are absent in plant cells.
B. Because inertia is the speed of the object and if the object weighs less, it falls faster :)
Answer:
There is a really good A P P for this in the A P P store
Explanation:
I C A N T type it on H E R E
a. <em>Monatomic ions
</em>
Cs is in Group 1. It has <em>one valence electro</em>n that it can lose to form a Cs⁺ ion.
Mg is in Group 2. It has <em>two valence electrons</em> that it can lose to form an Mg²⁺ ion.
N is in Group 15. It can gain <em>three valence electrons</em> to complete its octet and form an N³⁻ ion.
b. <em>Ionic compounds</em>
In an ionic compound there must be the same number of positive and negative charges.
It takes <em>three Na⁺ ions</em> to balance the charge on <em>one N³⁻ ion</em>, so the formula of sodium nitride is Na₃N.
It takes <em>three Mg²⁺ ions</em> (charge = +6) to balance the charge on <em>two N³⁻ ions</em>
(charge = -6), so the formula of magnesium nitride is Mg₃N₂.
