The correct answer is option (A) Prokaryotic cells do not have a true nucleus or membrane-bound organelles.

Cells are classified into prokaryotes and eukaryotes based on the presence of nucleus and membrane- bound organelles. Prokaryotic cells are the primitive cells that lack a well defined nucleus and membrane-bound organelles. The genetic material is in the central region of the cell called the nucleoid. They include the bacteria and the archaea. Eukaryotic cells are the cells which have a true nucleus or a well defined nucleus and all the membrane bound organelles. They include the protists, fungi, plants and animals.

Prokaryotic cells also possess a cell wall, viruses are neither prokaryotes nor eukaryotes and bacteria are prokaryotic. Hence the basic difference between the prokaryotic cells and eukaryotic cells is that the prokaryotic cell do not have a nucleus and membrane-bound organelles.

Why do polygenic characteristics have many phenotypes?
chubhunter [2.5K]

Answer:

The involvement of more than two genes.

Explanation:

The polygenic characteristics have many phenotypes because more than two genes governs the phenotype of individual organism. The single gene contains a pair of alleles that codes for two phenotype and two genes will code for 4 phenotype. Thus, more than two genes for example, three genes will have six phenotypes.

The skin color and height are polygenic characterstics in humans.

Halobacterium has a photosynthetic membrane that appears purple. its photosynthetic action spectrum is the inverse of the action
a_sh-v [17]

Yellow- Green Wavelength of light at peak absorption of 565nm.

Halobacterium is known to be a member of Archaea and they thrive in very salty environment such as Great Salt lake and Dead Sea. Halobacteria under the process of photosynthesis with chlorophyll and they make their ATP from the sunlight using bacteriorhodopsin and halorhodopsin as photosynthetic pigments.

However, photosensory pigements found in Halabacterium were:

1. photosystem 565 which is used to respond to yellow –green light in other for cell to find optimum conditions for ATP synthesis and photophosphorylation and they have peak absorbtion at 565nm.

2. Photosystem 370 nm appears to be responsible for the protective avoidance of blue/UV light.

Atp is not generated directly in the citric acid cycle. Instead, an intermediate is first generated by substrate-level phosphory
vagabundo [1.1K]

ATP is not generated directly in the citric acid cycle. Instead, an intermediate is first generated by substrate-level phosphorylation. The intermediate is GTP.

<h3>What is GTP?</h3>
  • A purine nucleoside triphosphate is guanosine-5'-triphosphate.
  • It serves as one of the components necessary for the creation of RNA during transcription.
  • The main distinction between its structure and that of the guanosine nucleoside is the presence of phosphates on the ribose sugar of nucleotides like GTP.
  • Also known as guanosine triphosphate, this energy-dense nucleotide is similar to ATP and is made up of guanine, ribose, and three phosphate groups.
  • It is required for the creation of peptide bonds during protein synthesis.
  • Adenine nitrogenous base, sugar ribose, and triphosphate make up ATP, a nucleoside triphosphate, whereas guanine nitrogenous base, sugar ribose, and triphosphate make up GTP.
  • This is the main distinction between the two compounds.
  • The alpha-guanosine subunit's diphosphate (GDP) is converted into guanosine triphosphate (GTP), and the GTP-bound alpha-subunit subsequently separates from the beta- and gamma-subunits.
