Which of the following would be classified as hydrophobic? Glucose, sucrose,NaCl, long chain fatty acid, pepsin

2 answers:

8 0

Hydrophobic means they don't mix with water and that they are non polar. glucose and sucrose are both sugars and we know sugar disolves in water, NaCl is that same as salt which dissolves in water, fatty acid become more hydrophobic as their tails get lo get longer so a long tail would be hydrophobic, and I'm not sure about pepsin.
So long chain fatty acids, and maybe pepsin

Answer:

long chain fatty acid

Explanation:

A hydrophobic or non polar substance repels water while a hydrophilic or polar substance is attracted towards it. Glucose and sucrose are types of sugar molecules and sugar easily dissolves in water hence they are not hydrophobic. NaCl or salt is also soluble in water hence its not hydrophobic. Pepsin is an enzyme that helps in breakdown of protein and is not hydrophobic.

Fatty acid is composed of a carboxylic group and a hydrocarbon chain. The hydrocarbon chain makes it non polar so longer the chain, more non polar the fatty acid becomes making it more hydrophobic.

In fruit flies, straight wings are dominant and curly wings are recessive. What will the generations look like? Assume that Mend

anzhelika [568]

Answer:

The P generation has straight wings and curly wings.

The F1 generation has all straight wings.

The F2 generation has straight wings and curly wings.

Explanation:

This question involves a single gene coding for wing shape in fruit flies. The allele for straight wings (S) is dominant over the allele for curly wings (s). This means that allele "S" will mask the phenotypic expression of allele "s" in a heterozygous state.

According to the question, the cross follows all Mendel's method of crossing two true breeding parents with opposite traits. Hence, the parent generation (P generation) will be between a truebreeding straight wings parent (SS) and a truebreeding curly wings parent (ss). (See attached image for full cross).

Since the straight wing allele (S) is dominant, all the F1 offsprings will possess straight wings with the genotype: Ss, which is heterozygous.

If this F1 offsprings are self-crossed i.e. Ss × Ss, four possible offsprings in the phenotypic ratio 3 straight wings : 1 curly wing will be produced in the F2 generation. The offsprings will possess the following genotypes: SS, Ss, Ss, and ss.

Offsprings SS, Ss, and Ss will all be phenotypically straight-winged

Offsprings ss will be phenotypically curly-winged.

In overall, this means that P generation has both straight and curly wings (SS and ss), F1 generation has only straight wings (Ss), F2 generation has both straight and curly wings (SS, Ss and ss).

Allisa [31]

Answer:

C. Document the number of honey-making bees per hive.

Explanation:

Among the given options, the only useful criteria towards the experimental design of honey production are to "document the number of honey-making bees per hive". We know that the increased number of animals would increase the workforce and thus increase the production of honey (direct relation). Therefore, this will give a direct assessment of honey production.

Which factors determine whether a cell enters G0?

Delvig [45]

The appropriate answer for this one is C. Cancer cells divide uncontrollably and therefore the cell cycle would be continuously divide. To add, there is a term known as terminally differentiated cells. These cells that never enter the cell cycle again, meaning they stay in G0 and never divide. However, some cells can be triggered to depart G0 and re-enter G1, which permits them to divide again.

here is the awnsers hope it helps you...
