Answer:
A. Archaea / Bacteria
Explanation:
Bacteriorhodopsin is a protein used by Archaea, most notably by halobacteria, a class of the Euryarchaeota. It acts as a proton pump; that is, it captures light energy and uses it to move protons across the membrane out of the cell
Bacteriorhodopsin is an integral membrane protein usually found in two-dimensional crystalline patches known as "purple membrane", which can occupy up to nearly 50% of the surface area of the archaeal cell.
Proteorhodopsin also known as pRhodopsinbis a family of over 50 photoactive retinylidene proteins, a larger family of transmembrane proteins that use retinal as a chromophore for light-mediated functionality, in this case, a proton pump
Answer:
Any three ways are:
1. Increase in Carbon Dioxide.
2. Loss of both plants and animals.
3. Land slides will take place.
Deforestation affect the world climate by :
1. Averaged over all land and oceans surface.
2. Global warming.
3. Loss of fresh oxygen.e.t.c.
Answer:
The correct answer is - biological hierarchy.
Explanation:
Biological hierarchy can be understand as the comprehension of the simplest form of the life to the most broadest and complex form of the life. It includes from the atoms which is a smallest structure and cells to the interactions of in between non living things and living things.
The broadest or highest level of the organization is biosphere in biological hierarchy in includes all other living organisms with non living things present in it. atoms to cell, tissue, organ, organ system to organism. these organisms shows interaction with each other and called populations that form communities, to ecosystem and finally biosphere.
Thus, the correct answer is - biological hierarchy.
2 amino acids; codon = a triplet & 1 codon codes for 1 amino acid therefore if are 2 mRNA codons then you’ll have 2 amino acids
How do the genes in our DNA influence our characteristics? For example, how can a gene determine
whether a person is an albino with very pale skin and hair?
Basically, a gene is a segment of DNA that provides the instructions for making a protein, and
proteins influence our characteristics. This chart describes how two different versions of a gene result
in two different versions of a protein which in turn can result in either normal skin and hair color or
albinism.
DNA Protein Characteristic
Version of the gene that provides
instructions to make
normal protein enzyme
Normal enzyme that makes the
pigment molecule in skin and
hair
Normal skin and hair
color
Version of the gene that provides
instructions to make
defective enzyme
Defective enzyme that does
not make this pigment
molecule
Albinism (very pale
skin and hair)
A gene directs the synthesis of a protein by a two-step process.
The first step is transcription of the gene in the DNA.
Transcription produces a messenger RNA (mRNA) molecule.
The second step is translation of the mRNA molecule.
Translation produces a protein molecule.
During transcription, the sequence of
nucleotides in a gene in the DNA is
copied to a corresponding sequence
of nucleotides in mRNA.
During translation, the sequence of
nucleotides in the mRNA determines
the sequence of amino acids in the
protein.
After translation, the sequence of amino acids in the protein determines the structure and function of
the protein. Differences in protein function can influence characteristics such as normal skin and hair
color vs. albinism.
