Answer:
The oxygen atoms have electrons more often than hydrogen.
Explanation:
Answer: Fluorescence microscope
Explanation:
The basic function of a fluorescence microscope is to irradiate the specimen with a desired and specific band of wavelengths. A fluorescence microscope uses a mercury or xenon lamp to produce ultraviolet light. The light comes into the microscope and hits a dichroic mirror. The dichroic mirror reflects the ultraviolet light up to the specimen. The ultraviolet light excites fluorescence within molecules in the specimen. The objective lens collects the fluorescent-wavelength light produced. This fluorescent light passes through the dichroic mirror and a barrier filter, making it to the eyepiece to form the image.
Answer:
B) cells or tissue that produce light
Explanation:
It wouldn't be A because photophores do not affect the color of other organisms.
It wouldn't be C because the cells produce light, they don't necessarily change color.
Lastly, it wouldn't be D because it isn't a whole organism producing the light, it's an organ. Organs are multiple tissues working together, and tissues are groups of cells.
Cysteine contributes to the three-dimensional structure of a protein by forming covalent bonds with an identical amino acid in another part of the protein.
<h3>
What is the Cysteine Structure?</h3>
- Covalent disulfide bonds form between the sulfhydryl (-SH) groups of cysteines in different parts of a protein are very important in determining the three-dimensional shape of the protein.
- is a HOOC-CH-(NH2)-CH2-SH proteinogenic amino acid that is semi-essential. Cysteine's thiol side chain frequently functions as a nucleophile in enzyme processes.
- The sign Cyz is occasionally used when a deprotonated catalytic residue is present.
- The sign Cym can also be used to usually denote the deprotonated form.
- The thiol is capable of being oxidized to produce the disulfide derivative cystine, which is crucial for many proteins' structural integrity. Cyx is sometimes used in this context. It carries the E identifier E920 when added to food.
- The codons UGU and UGC encode the amino acid cysteine.
- Cysteine and methionine, which contain sulfur, are more quickly oxidized than other amino acids.

Answer:
DNA which is a nucleic acid
Explanation:
DNA is a polymer. The monomer units of DNA are nucleotides, and the polymer is known as a "polynucleotide." Each nucleotide consists of a 5-carbon sugar (deoxyribose), a nitrogen containing base attached to the sugar, and a phosphate group.
