Because nonrenewable resourses are made by the earth
The correct answers are: Archaea lack true peptidoglycan in their cell walls; The cytoplasmic membrane lipids of archaea have branched or ringform hydrocarbon chains.
The cell wall of all bacteria contains peptidoglycan. Archaeal cell walls do not contain this compound, though some species contain a similar one.
The Bacteria have membranes composed of unbranched fatty acid chains attached to glycerol by ester linkages. The Archaea have membranes composed of branched hydrocarbon chains attached to glycerol by ether linkages.
Answer:
The correct answer is option e. "result in permanent activation of Ras".
Explanation:
Ras function is regulated by the GTP/GDP cycling rate, in a way that Ras is inhibited by the substrate GDP. Once Ras hydrolyzes GTP, GDP is produced and Ras is inhibited by GDP. A mutation that inhibits Ras from hydrolyzing GTP, would lock Ras in a permanently activated state because no GDP would be produced and there will be no substrate to inhibit Ras.
I had to look for the options and here is my answer.
The GINGKOS, GNETOPHYTES and CYCADS are the closest relatives of the familiar pine and spruce trees. These plants are coniferous and belong to the plant <span>family Pinaceae. They are coniferous in a way that they produce hanging cones and have needle shaped leaves.</span>
