Answer:
B. Two groups of monerans-Eubacteria and Archaebacteria--differed significantly from one another
Explanation:
It was Carl Woese who divided the prokaryotes into 2 kingdoms, Eubacteria and Archaebacteria based on RNA studies. So. this led to additional 6th classification added to Whittaker's classification of 5 kingdoms.
I wouldnt say that it has much to do with latitiude eventbkigh there are quite a few at both of the poles. It usually corresponds wirh altitude. There are glaciers in every continent.
The first process is called transcription where the DNA's information is used to make mRNA. The second process is called translation where the tRNA comes with an amino acid to drop off. A chain of amino acids will eventually be formed to create a protein. Transcription comes before translation. Think that you have to script something before you can translate it.
Answer:
A
Explanation:
It allows the cell to control what materials enter and leave.
Answer:
The correct answer will be option-D
Explanation:
The aerotaxis movement experiment performed by the Theodor W. Engelmann played an important role in understanding the photosynthesis.
The experiment was performed on the <em>Spirogyra </em>filamentous algae which were exposed to a different wavelength of light.
The other aerobic bacteria present in the test tubes started moving and accumulated near the two regions of the <em>Spirogyra</em> where they were exposed to the blue and red light of the VIBGYOR.
The region receiving red and blue light produced more oxygen through photosynthesis which indicated that these two wavelengths of the light are more active for photosynthesis than any other wavelengths.
Thus, option-D is the correct answer.
