Answer:

Unfortunately, this temperature is on the order of billionths of a kelvin for black holes of stellar mass, making it essentially impossible to observe directly. Objects whose gravitational fields are too strong for light to escape were first considered in the 18th century by John Michell and Pierre-Simon Laplace.

which of the macromolecules tested in this exercise (proteins, lipids, nucleic acids) were formed by dehydration reactions? expl
aalyn [17]

Large polymers are created during dehydration synthesis, which are typically referred to as biological macromolecules. These compounds include proteins, lipids, carbohydrates, and nucleic acids.

As a result, the dehydration reaction is responsible for the formation of protein, lipid, and nucleic acids.

1. Protein structure

  • Amino acid polymers form proteins. There are four different types of proteins, based on structure.
  • The amino acid sequence of a protein is represented by its primary structure, which is a linear chain.
  • The backbone (main chain) atoms of a polypeptide are arranged locally in space to form the protein's secondary structure.
  • A polypeptide chain's whole three-dimensional structure is referred to as a protein's tertiary structure.
  • The protein's quaternary structure, which is a three-dimensional arrangement of the subunits of a multi-subunit protein.

2. Lipid structure is a crucial element of the cell membrane. The structure is mostly composed of a glycerol backbone, two hydrophobic fatty acid tails, and a hydrophilic phosphate group.

3. Nucleic acids' structure: Nucleotide polymers make up nucleic acids. Each nucleotide is made up of an aromatic base with a N-atom connected to a pentose sugar with five carbons, which is then joined to a phosphate group.

alina1380 [7]

The given question is incomplete, the complete question is:

Raquel is having difficulty becoming pregnant, and her doctor believes it could be due to the position of her uterus. Which organ should the body of the uterus be immediately superior to in the pelvis? Multiple Choice Urinary bladder Rectum Ovary Vagina

Answer:

The correct answer is urinary bladder.

Explanation:

In the pelvis, the urinary bladder is the organ to which the body of the uterus would be immediately superior. In the pelvis or the lower abdomen, a pear-shaped hollow composition, present between the urinary bladder and the rectum is known as the uterus. The structure or the composition located superiorly lateral to the uterus body and associated with the utero-ovarian ligament is known as the ovary. The vagina and the rectum are located underneath the uterus or the uterine cavity.
