A fatty acid has two main parts: 1) a long hydrocarbon chain and 2) a carboxylic acid group. The hydrocarbon chain is how we can tell if it is saturated or not. If there are carbons-carbon double bonds, then it would be unsaturated. Saturated fatty acids have no double bonds.
Fatty acids are very important to the body for several reasons. They are essential to the structure of the cell membrane, they can be used for long term energy storage, healthy brain function, targeting molecules for many proteins, as well as cellular messengers.
Answer:
You can't see the blood vessels themselves because vision depends on a process that makes it impossible to see things that are stationary with respect to the retina. Light receptors in the retina respond only to changes in light reaching them, not to a steady image.
Have a great day! :D
Answer:
When two heterozygous short haired rabbits are crossed, the short hair being dominant and the long hair recessive, the phenotypes in the offspring will be 75% short hair and 25% long hair, with a short hair:long hair ratio of 3:1.
Explanation:
The crossing of two hybrid individuals for a trait has the probability of producing <u>offspring that exhibit the dominant trait at 75% and the recessive trait at 25%, with the ratio of the dominant trait to the recessive trait being 3:1</u>.
Considering the hair length trait, in rabbits the short hair (L) is the dominant trait and the long hair (L) is recessive, two heterozygous hybrid individuals Ll are crossed:
<em><u>Genotype of the parents</u></em>:
Ll X Ll
<u>Punnett Square
</u>
Alleles L l
L LL Ll
l Ll ll
Where the offspring have a genotype:
<em>Ll 50%
</em>
<em>LL 25%
</em>
<em>ll 25%
</em>
With a ratio Ll:LL:ll of 3:1:1.
Phenotype:
<em>Short hair 75%.
</em>
<em>Long hair 25%.
</em>
Phenotypic ratio short hair: 3:1 long hair.
In the crossing of two heterozygous short-haired rabbits, taking into account the dominance of the short hair, phenotypes in the offspring will be 75% short hair and 25% long hair, with a short hair:long hair ratio of 3:1
