In aqueous solutions, the charged hydrophilic heads of phospholipids are attracted to the water phase, and the nonpolar hydrophobic tails are repelled.

Phospholipids may be defined as ad amphipathic molecule that consists of fatty acids, a phosphate group, and an alcohol attached to the phosphate.

The hydrophilic heads of the phospholipids are water-loving which consists of the phosphate group while the hydrophobic tails of the phospholipids are water-hating that comprises of fatty acids.

Therefore, in aqueous solutions, the charged hydrophilic heads of phospholipids are attracted to the water phase, and the nonpolar hydrophobic tails are repelled.

If we have the recessive genotypic frequency, we can calculate the phenotypic frequencies in a population in Hardy-Weinberg equilibrium. The percentage is 82%.

The Hardy-Weinberg equilibrium theory states that allelic and genotypic frequencies remain the same through generations in a population that is in equilibrium.  

The allelic frequencies in a locus are represented as p and q. Assuming a diallelic gene,

Allelic frequencies

Genotypic frequencies after one generation are

• p² ⇒ H0m0zyg0us dominant genotypic frequency,

• 2pq ⇒ Heter0zyg0us genotypic frequency,

• q² ⇒ H0m0zyg0us recessive genotypic frequency.

The addition of the allelic frequencies equals 1

p + q = 1.

The sum of genotypic frequencies equals 1

p² + 2pq + q² = 1

Available data:

18% of individuals express the recessive trait of Syndactyly

Let us say that the dominant allele is A and the recessive allele is a.

Assuming this gene expresses complete dominance,

Their frequency in the population is p² + 2pq.

Their frequency in the population is q².

Individuals that express Syndactyly have webbed finger and their genotype is h0m0zyg0us recessive, aa. Their frequency in the population is q².

q² = 18% = 0.18

We can get the frequency of individuals with normal fingers by clearing the following equation,

p² + 2pq + q² = 1

p² + 2pq + 0.18 = 1

p² + 2pq = 1 - 0.18

p² + 2pq = 0.82

The frequency of individuals with normal fingers is p² + 2pq = 0.82 = 82%.

The percentage of the population are not Webbed is 82%.

Fats with at least one double bond between carbon atoms are unsaturated fats. When some of these bonds are in the cis configuration, the resulting bend in the carbon backbone of the chain means that triglyceride molecules cannot pack tightly, so they remain liquid (oil) at room temperature.

Davy made a model of the water cycle by adding some water inside a plastic bag, sealing the bag, and placing it in a sunny area. He noticed that the level of the water went down, and then some droplets appeared on the sides of the bag. which part of the water cycle caused water droplets to form on the side of the plastic bag?  

(a) condensation (b) evaporation (c) precipitation runoff

The part of the water cycle that caused water droplets to form on the side of the plastic bag would be condensation.

It is a process whereby water vapor in the atmosphere condenses or turns back into liquid.

Condensation is as opposed to evaporation. The latter is a process whereby liquid water turns into vapor water. In other words, evaporation and condensation are words and opposites.

Both processes play a major role in the water cycle of the ecosystem.

Nucleotides from the DNA template strand complement the mRNA's codons. These codons code for amino acids. Option B is correct. CAA - CTA - TCG

Nucleotides are monomers composed of a sugar molecule, joined with a phosphate group and a nitrogenated base.

Several nucleotides joint by their extremes compose the nucleic acids.

Nucleotides have a certain order or sequence in nucleic acids, which is significant since these sequences carry biological information neccesary to carry out cellular functions.

Codons are short sequences of three nucleotides that carry genetic information needed to build the protein. These units determine which amino acids are added to the growing chain during the assembly.

More than one codon might code for the same amino acid.

Different sequences of three nucleotides -codons- might code for a different amino acid. This means that the resulting proteins will not be the same, and they will accomplish different functions.

When DNA molecule unwinds to be transcripted, two single strands get separated,

It receives that name because it is the sequence that codes for each amino acid composing the proteins.

When referring to the coding strand, we are talking about the sequence that turns out to be the same as the mRNA that results from the transcription of the same DNI segment -switching bases T for U-.

This is the one that is used during transcription to synthesize mRNA. The template strand is the one that is going to be complemented by the mRNA.

To get to know the sequence of nucleotides in the template strand that code for the polypeptide sequence val-asp-ser, firts we need to know which codons code for these amino acids.

1)

Amino acid            Codon

Val                          GUU, GUC, GUA, GUG

Asp                         GAU, GAC

Ser                          UCU, UCC, UCA, UCG, AGU, AGC

These are all the possible codons in mRNA that might code for these amino acids. Now, we need to identify their complementary bases on the template strand.

2)

mRNA        Template strand

GUU                  CAA

GUC                  CAG

GUA                   CAT

GUG                  CAC    

GAU                   CTA

GAC                   CTG    

UCU                   AGA

UCC                   AGG

UCA                   AGT

UCG                   AGC

AGU                   TCA

AGC                   TCG  

The column of the right shows all the possible nucleotides that might complement the mRNA codons. There are several combinations. Now, we need to choose among the options the correct combination.

3)

Options A and  D  ⇒  guu-gau-agc and caa-cua-ucg

These are not the correct options since they carry uracils instead of thymines. Remember that DNA molecules have thymine, and RNA molecules have uracil.

Option C ⇒ gtt-gat-agc

This is not correct since these sequences do not complement the mRNA codons.

Option B ⇒ caa-cta-tcg

This is correct. You can find these nucleotide sequences among the options written before for the template strand.

Option B) CAA - CTA - TCG is the correct one.

All cells contain cytoplasm, which is made up of cytosol, a jelly-like substance. The cytosol holds the internal structures in suspension.

In addition to the nucleus, eukaryotic cells also have other organelles. An organelle is a cytoplasmic structure that serves a specialized purpose for the cell.

For instance, organelles called vacuoles store materials in the cell, whereas organelles called mitochondria supply energy.

The space between the plasma membrane and the nuclear envelope is known as the cytoplasm in eukaryotic cells, which have a nucleus.

The term “cytoplasm” refers to the entire inside the plasma membrane in prokaryotes, which are without a nucleus.

Selective breeding is a technique to obtain offspring with desired traits, characteristics of cattle include meat and height, whereas wheat is obtained by crossing high yield plants.

Selective breeding is a human technique used to obtain descendence (either plants or animals) from a given genetic cross.

This technique (selective breeding) is used in agriculture to obtain wheat with higher grain yields.

Two characteristics of cattle that have been human-driven selected include meat and average size (height).

It is possible to obtain wheat with desired features by crossing plants having desired genes (it is an autogamous plant).

The characteristics of the chickens (Kendo and Bibby) are not found here, but it is possible to select desired phenotypes by crossing them and selecting offspring.

Glaciers grow smaller, causing sea level to rise when Earth's global temperature is lower. Thus, the correct option is C.

Sea level lowers during cold climate periods, known as glacial epochs or ice ages, due to a shift in the global hydrologic cycle, in which water evaporates from the oceans and is stored on the continents as massive ice sheets, extended ice caps, ice fields, and mountain glaciers. At the last glacial maximum, some 20,000 years ago, global sea level was about 125 meters lower than it is today.

Because the melting North American, Eurasian, South American, Greenland, and Antarctic ice sheets returned their stored water to the world's oceans as the climate warmed, sea level rose. Sea level is at its highest during the warmest eras, known as interglacial epochs.

We are currently living in the most recent interglacial, which began around 10,000 years ago and is referred to by geologists as the Holocene Epoch. Sea levels were about 3 to 20 meters higher than they are now during several previous interglacials.
