Answer:
Archaebacteria
Explanation:
Archaebacteria is a group of single-celled organism present on the earth which are thought to be descended from the ancient bacteria.
These bacteria can survive the extreme or harsh conditions present on the Earth-like in the hot springs.
The archaebacteria cell membrane is made up of ether-linked phospholipids which are ester-linked in Eubacteria and eukaryotes. The sugar present in the archaebacteria is very similar to peptidoglycan in composition but it is not peptidoglycan.
Thus, Archaebacteria is the correct answer.
I think the answer is true not 100% tho
Answer:
C. Promoter; Operator
Explanation:
Related genes in bacteria are often found in a cluster on the chromosome, where they are transcribed from one RNA polymerase binding site(promoter) as a single unit while other regulatory proteins are binding repressors attached to DNA pieces known as operators. When they are bound to operator, a repressor reduces transcription.
Genes in cases like this encode proteins, having various roles which include fuel metabolism, maintenance of cell structure, and
also defense against viruses in its process. A great number of these proteins are been used while others are needed only under certain decrees. Therefore, it is said that cells don't express all the genes in their genome always.
Answer:
B
Explanation:
The x coordinate is basically giving us the amount of fertilizer in grams.
The y coordinate is giving us the average height of the plant because of the corresponding fertilizer.
A point of (1,25) would tell us that 1 grams of fertilizer given, the average height of those plants would be 25 cm.
So, if we give 1 grams of fertilizer, those plants' average height became 25 cm.
From the answer choices, B is the correct answer.
