You are called upon to visit the ailing Col. Lemon. Before you see him, you speak to three witnesses who were with him when he fell ill...
- Ms. Magenta: "Col. Lemon has been hot-blooded for as long as I have known him. But I noticed that he couldn't seem to keep warm. He kept complaining about being cold."
- Mr. Olive: "Just between you and me, I've noticed that the old chap has put on quite a bit of weight lately."
- Prof. Purple: "The colonel and I used to go on major expeditions together. Now he just doesn't seem to have the energy for much of anything."

What are your initial thoughts about the witness statements? Does one hormone come to mind that may be the cause?

What about amino acids is true?
They have at least 1 amino group and at least one carboxyl group.
The variable side chains of all of the amino acids are highly reactive and carry a charge at neutral pH.
The peptide bond that bonds the amino acids together in a protein is a type of covalent bond, which means that proteins are stable at high temperatures.
The variable side chains of amino acids are hydrophilic and that allows the polypeptides to be soluble.
When forming proteins, a condensation reaction links the amino group of one of the amino acids to the variable side chain of the adjacent amino acid.
What happens as a result of fat being synthesized?
Three fatty acid molecules combine with a molecule of glycerol to produce a molecule of fat plus three molecules of water.
All bonds between the carbon atoms in the hydrocarbon chain become single bonds.
One fatty acid and one glycerol molecule are condensed.
One fatty acid and one glycerol molecule are hydrolyzed.
Three fatty acid molecules are hydrolyzed by three molecules of water and one molecule of glycerol that produces a fat molecule.

Directions: For the following problem, calculate the probability
of the offspring between the cross using the sum and product
rule.
The parent generation has genotypes of AA Bb CC
Dd and Aa bb Cc dd. What is the
probability the F1 generation would be Aa bb Cc dd
or AA bb Cc dd?

Glycine, alanine, threonine
Phenylalanine, tyrosine, tryptophan
Valine, leucine, isoleucine
Arginine, lysine, histidine

2. Which group of amino acids are metabolized mainly in skeletal muscles?
Those with side chains containing aromatic rings
Those with side chains that are branched
Those with side chains containing basic groups
Those with side chains containing sulfur atoms

3. Hyperhomocysteinemia is an independent risk factor for cardiovascular disease. Homocysteine is endogenously generated from:
Cysteine
Threonine
Methionine
Taurine

Biology

In an experiment, researchers determined that applying a cyclin called CLB3 during early prophase I led to premature interactions between the kinetochores of sister chromatids and microtubules. How would this interaction affect the chromosome distribution at the end of meiosis I?

Sister chromatids would separate instead of homologous chromosomes, leading to a diploid number of chromosomes from one parent.

Homologous chromosomes would separate instead of sister chromatids, leading to a diploid number of chromosomes from both parents.

Homologous chromosomes would separate instead of sister chromatids, leading to a haploid number of chromosomes from both parents.

Sister chromatids would separate instead of homologous chromosomes, leading to double the number of original chromosomes from one parent.
