Answer: 18
Explanation:
This molecule, called ammonia, is a group of atoms held together by chemical bonds. In this example, the atoms (smallest pieces of matter) are nitrogen (N) and hydrgoen (H)
The number 6 indicates the number of moles of the NH3 molecule. A mole is the unit of measurement used to measure the number of atoms or molecules. One mole is equal to 6.02214078×10^23 of the same things.
And since there are 3 Hydrogen atoms found in each mole of ammonia, and there are 6 moles of amminia, then 6 x 3 = 18 atoms of hydrogen.
No 6 is common for N and H. 3 is only for H(Hydrogen).
For finding the number of hydrogen atoms we should multiply 6 with 3
So, 6*3 = 18. So there will be 18 hydrogen atoms in 6NH₃
Correct answer: B). People are warned to avoid eating shrimp and lobster.
People are warned to avoid eating of lobster and shrimp that would be least likely to be seen on a pamphlet of red tide because lobsters and shrimp are not affected by the red tides.
The fishes that are affected by red tide are shellfish and oysters. so if someone consumes shrimp and lobster then it would not create any problem related to red tide. Red tide is considered harmful to humans and they can cause death if consumed.
The information pamphlet for red tide is ‘People are warned to avoid eating shrimp and lobster’. Because eating one will likely cause death du tot poisononing.
B. The breakdown of glucose into pyruvic acid
c. Krebs cycle
2. Within the light-independent reactions, what can be said about the 3-carbon-atom molecules produced?
A. Some of these molecules are converted back into 5-carbon-atom molecules to regenerate the cycle.
b. All of these molecules leave the cycle to make sugars
.
c. All of these molecules are combined with carbon dioxide.
3. Which of the following accurately describes the patterns of inheritance in human blood types?
A. Three alleles code for blood types and three phenotypes are possible.
B. Allele IA and IB are codominant, and allele i is recessive.
c. Allele i is dominant over alleles IA and IB.
4. A cell can only grow so large in size, because
A. its surface-to-volume ratio decreases as the cell becomes larger.
b. its ability to exchange materials would happen more quickly as the cell grows.
c. its surface-to-volume ratio decreases as the cell becomes smaller.
5. Which of the following accurately describes the relationship between photosynthesis and cellular
respiration?
a. Cellular respiration provides photosynthesis with oxygen and sugar.
b. The reactants of photosynthesis are the products of cellular respiration and vice versa.
c. All living organisms must choose only one of these processes for their entire lives.

Explanation:
Answer:
All life on Earth consists of either eukaryotic cells or prokaryotic cells. Prokaryotes were the first form of life. Scientists believe that eukaryotes evolved from prokaryotes around 2.7 billion years ago.
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information. In prokaryotes, DNA is bundled together in the nucleoid region, but it is not stored within a membrane-bound nucleus.
The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles. Another important difference is the DNA structure. Eukaryote DNA consists of multiple molecules of double-stranded linear DNA, while that of prokaryotes is double-stranded and circular.
