Most of a cell's molecules can be classified as belonging to one of four major classes: lipids, carbohydrates, nucleotides, or a
goblinko [34]

Answer:

Diagram, in attachments

Explanation:

From the left side of the screen to the right,that is from a structure with a sugar structure with two other molecules  attached to it.

The first molecular structure is Nucleotides. Reasons it contains the middle ribose sugar(5-carbon)connected to the phosphate group and  Nitrogenous bases.This is the structure of nucleotides  and when this is joined by phosphodiester bond between one a nucleotide, to the phosphate group of another  nucleotide molecule  it forms a nucleic acid molecule.

The second structure from left to right with  long carbon chains, it is  a lipid.That js an Ester formed from the reaction of fatty acids with alcohol glycerol.

However, the presence of Phophate group in structure makes it different from a normal tryglycerides.The phosphate group has replaced  one of the  the three fatty acid molecules.Therefore it is called Phospholipid.With one hydropholic ends(phosphate ends) and the hyrophobic end the  carbon chain,with one unsaturated. The lipids molecules are held together my ester bonds.

The next structure is the protein structure(dipeptide).Genrally amino acid is made up of the central Alpha carbon connected on the right by the Carbonyl group(coo-) on the left by the Amine(NH2) group.The R-group which determines the type of amino acids  and hyrdogen atom.In the above structure condensation reaction  has occurred between the hydrogen atom  of  the amine group and carbonyl group of the other amino unit to form a dipeptide.The  bond formed from the condensation is the peptide bond.

The last structure on the far right are the carbohydrate -ring structure and the straight chains.The functional groups of the CHO  -Carbonyl group and hydroxyl group are glues to this.

Consider a population of 425 diploid giant Sequoia trees. In this population, you observe the following genotypic counts: 100 ho
Lemur [1.5K]

Answer:

q = 0.42

Explanation:

This question is an example of Hardy-Weinberg question and there are two equations necessary to carry out this question;

p + q = 1

p² + 2pq + q²  = 1

where;

p = the frequency of the dominant allele

q =  the frequency of the recessive allele

p² = the frequency of individuals with homozygous dominant genotype

2pq  = the frequency of individuals with heterozygous genotype

q² = frequency of individuals with the homozygous recessive genotype

Since the total  population = 425

q² = \frac{individuals with recessive genotype}{Total Population}

= \frac{75}{425}

q² = 0.1765            

To find q; we need to square root both side to           eliminate the square from  q².

∴ \sqrt{q^2}=\sqrt{0.1765}

q = 0.4201

q = 0.42       (to two decimal places)

Air masses move from areas with high pressure (such as the poles of the Earth) to areas with low pressure (the equator). The tem
valina [46]

Answer:

B

Explanation:

Warm because land gains heat faster than water when heated by the sun. The heated land then transfers the heat to the atmosphere. The air mass is dry becasue a continent is mainly land and very little water (unlike oceans). There is, therefore, very little moisture in the continental tropical air mass.
