Vegetable oil is........................the phospholipids in vegetable oil have fatty acid tails that ARE BEND.
Vegetable oil are made up of unsaturated fatty acids, which means that double bonds are present in the oil. The degree of unsaturation varies depending on the type of oil. The configuration for double bond is cis; this makes the phospholipid in the vegetable oil to have bent structure.

How is the energy of chemical processes coupled in metabolic pathways?
SCORPION-xisa [38]

Answer:

Energetic coupling of chemical processes in metabolic pathways Biochemical systems couple energetically unfavorable reactions with energetically favorable reactions. These reactions can be part of catabolic pathways where complex substances are broken into simpler ones with the release of energy or anabolic pathways where complex molecules are synthesized with an input of energy.

In ________and ________ no energy is used. Which one needs a helper to get things across?__________
MissTica
In DIFFUSION AND FACILITATED DIFFUSION no energy is used. The one that needs a helper to get thing across is FACILITATED DIFFUSION.<span> Facilitated diffusion involves the diffusion of materials across the cell plasma membrane with the aid of membrane proteins such as carriers and channels. The process of diffusion does not need a carrier, the molecules to be transported just move on their own from the area of high concentration to the region of low concentration until the concentration in the space become uniform.</span>

A cat with LONG HAIR (heterozygous) is a carrier of the short hair allele. Its mate has SHORT HAIR. Use a Punnett Square to dete
Helen [10]

Answer:

50%

Explanation:

Hi there!

We are given the hair types of two cats

The first one has long hair, and it's heterozygous, meaning it has one dominant, and one recessive allele. We are given that it is a carrier of the short hair allele, meaning in its genotype, it has the short hair gene (that doesn't necessarily mean it's there in its phenotype). However, since it has long hair (genotype), that means that the long hair allele is dominant (the gene that will always show), and the short haired one is recessive (the gene that gets "covered up" by the dominant allele). Let's say the genotype of the long haired cat is Tt, where T is the long hair, and t is the short hair  

The second cat has short hair, and as we have mentioned above, the allele for short hair is recessive, so the short haired cat has 2 copies of the short hair allele. Its genotype is tt

Please see below for the Punnett Square

Hope this helps! :)

A woman with brown eyes, which has two brothers, marries a man with brown eyes, which has a brother and two sisters, and produce
cupoosta [38]

Answer:

A. The man's genotype is Bb. Phenotypes of the offsprings:- heterozygous brown-eyed- homozygous blue eyedGenotypes of the offsprings:- Bb- bbb. The blue is recessive, so the woman's genotype is bb. It is impossible for her to have B because it is dominant over b.c. The woman can only produce bb or blue-eyed.d. The man's genotype is Bb. It is impossible for him to produce an offspring with blue-eyes if his genotype is BB.e. The man can produce Bb or brown-eyed and bb or blue-eyed.
