Answer:
B
Explanation:
Amino acids have a basic skeleton as shown in the illustration.An alpha carbon bonded to a carboxyl gorup, amino grpup, hydrogen, and a side chain. However, amino acids differ in their side chains. These side chains can give different amino acids different properties because of their different properties. The side chains give different properties to the amino acid such as size, shape, ionization properties, polarity, charge, acidity, and basicity.
Answer:
In allosteric inhibition, a regulatory molecule binds to a location other than the active site, resulting in a change in enzyme shape that allows the active site to bind substrate.
Explanation:
Allosteric regulation of an enzyme can be positive or negative, but it always involves effector molecules that bind to non-active site of the enzyme and change its conformation. That site of binding is called allosteric or regulatory site. If the enzyme activity is enhanced effector molecule is called allosteric activator but if the activity is decreased effector molecules are allosteric inhibitors.
Answer:
What color light is best absorbed by chlorophyll?
As shown in detail in the absorption spectra, chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants.
Explanation:
therefore it is blue
The daughter cells come together to make another identical parent cell.
Answer:
I believe the options are:
A) The diagram shows crossing over. Crossing over increases the genetic variation of the gametes produced in meiosis, by allowing for different allele combinations than present in the parents. This results in greater diversity in the offspring produced.
B) The diagram shows a chromosome mutation called translocation. Translocation introduces new traits into the gene pool of the gamete by trading genes between nonhomologous chromosomes. This results in greater diversity in the offspring produced.
C) The diagram shows crossing over. Crossing over introduces new traits into the gene pool of the gamete by trading genes between homologous chromosomes. This results in the formation of more diverse gametes.
D) The diagram shows a chromosome mutation called inversion. In inversion, a segment of a chromosome is reversed end to end. Inversion rearranges the genes on a chromosome, providing more diverse gametes.
The correct choice is: A) The diagram shows crossing over. Crossing over increases the genetic variation of the gametes produced in meiosis, by allowing for different allele combinations than present in the parents. This results in greater diversity in the offspring produced.
Explanation:
Crossing Over:
- Crossing over occurs in the Prophase 1 of Meiosis 1.
- By definition, it is the exchange of chromosomal segments between non-sister chromatids of homologous chromosomes.
- Through exchange of genetic segments, crossing over introduces genetic variations in the gametes.
- Genetically variant gametes fuse to produce an individual that varies in characteristics as compared to the parents.
