Compounds consist of atoms of different elements. In compound the atoms are present in fixed proportion. By changing the proportion compound will changed. For example,
Nitrogen and oxygen reacted to form the compound. By changing the proportion both will form different compound.
NO₂
Nitrogen dioxide consist of one atom of nitrogen and two atoms of oxygen. Their ration is 1 :2
NO
In nitric oxide one atom of oxygen and one atom of nitrogen are present.
Their ratio is 1 : 1.
N₂O
Nitrous oxide consist of two nitrogen atoms and one oxygen. Their ratio is
2 : 1
N₂O₄
Dinitrogen tetroxide consist of two nitrogen atoms and four oxygen atoms. Their ratio will written as 2 : 4
N₂O₅
Dinitrogen pentoxide consist of two nitrogen atoms and five oxygen atoms. Their ratio will written as 2 : 5
From the calculations, the rate of growth of the culture is 2.88.
<h3>What is exponential growth problem?</h3>
We apply the exponential growth problem when there is an exponential increase.
Thus, we have; P =Poe^rt
P = amount at time t
Po = amount originally present
t = time taken
r = rate of growth
1.6 × 10^6 = 16e^4r
1.6 × 10^6/16 = e^4r
1.0 * 10^5 = e^4r
ln 1.0 * 10^5 = ln e^4r
11.5 = 4r
r = 11.5/4
r = 2.88

<span>The trait that is ancestral to all chordates is the presence of a notochord...the others are gill slits and nerve chord</span>
Answer:
The correct statements are listed below.
Explanation:
Vitamins are organic and minerals are inorganic.
Organic compounds comes from living things.Vitamins generally exist as organic compounds for example all the vitamin such as vitamin A, Thiamine,riboflavin,biotin,pyridoxin,vitamin c,vitamin E, vitamin K exist as organic compounds.
On the other hand minerals are found in inorganic form for example nitrogen is found as nitrate and nitrite,phosphorus is found as phosphate group,phosphoric acid.
mitosis , a part of asexual reproduction because it produces diploids is the correct answer
