Which of the following best explains why a structural formula of a chemical compound is more useful than a molecular formula?
Fittoniya [83]

Answer: Both formulas identify the specific atoms in a particular compound. However, a structural formula also shows how the atoms in a compound are bonded together.

Explanation:

Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.  

Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.

Structural formula is the formula which depicts the actual number of atoms of each element present in the compound by showing the bonding between the atoms.

Lewis structures show the valence electrons around each atom present in the compound.

Which cellular structure(s) is/are present in prokaryotic cells,
vovikov84 [41]

Capsule is a structure present in prokaryotes but absent in eukaryotes.

<h3>What are prokaryotes? </h3>

Prokaryotes cells are cells that do not have structures bounded in a membrane. example include bacteria.

<h3>What are Eukaryotes?</h3>

Eukaryotes cells are organisms that have their nucleus and other organelles bounded in an enclosed membrane.

Prokayote e.g Some bacteria have capsules it is carbohydrates in nature and it enables the bacteria to attach themselves to the surface. This is not present in eukaryote cells.

Conclusively, Capsule is the structure present in prokaryotes but absent in eukaryotes.

Each species has a specific identifying number of chromosomes. For example, a cat, felis catus, has 38 chromosomes, while corn,
tester [92]

Answer:

Each species has a specific identifying number of chromosomes. For example, a cat, <em>Felis catus</em>, has 38 chromosomes, while corn, <em>Zea mays</em>, has 20 chromosomes each chromosome carries specific genes that are unique to that chromosome.

Explanation:

Chromosomes vary in shape and number among living beings. For example, the bacterial chromosome is a unique circular molecule, while human beings have 46 lineal chromosomes arranged in pairs (23 pairs). The total number of chromosomes is specific to each species, and it is denoted as the "chromosomic dotation" of the species.

Genes are the hereditable units that transmit the information needed to specify traits, from parents to offspring, generation to generation. Genes are arranged in sequence in the chromosomes. A chromosome might contain hundreds of thousands of genes.

Genes vary in size and shape.  They are composed of pairs of bases, and these sequences also vary in number, producing genes of different lengths. In general, genes code for proteins. Proteins create the organism tissues and perform or carry out specific functions in the organisms, controlling almost all processes and chemical reactions.

Each chromosome carries <u>specific</u> genes that code for <u>specific </u>proteins that have <u>specific</u> functions in the organisms. Each chromosome carries information to synthesize different proteins needed to accomplish a certain function. But <u>not all chromosomes carry the same gene sequences</u>. Only homologous chromosomes carry information for the same trait, but even this information is not necessarily the same. They might have the same gene but different alleles.
