Answer:

Carl Richard Woese

Explanation:

He was an American microbiologist and biophysicist. His main focus was upon genetic codification.

in 1977, Carl Woese and George E. Fox discovered a kind of microbial life which they called the “archaebacteria”. It composed "a third kingdom" of life different from bacteria, plants and animals. His three-domain system, divided life into 23 main divisions, incorporated within three domains: Bacteria, Archaea, and Eucarya.

Answer:

Carl Woese

Explanation:

Earlier scientists used to divide organisms in two major groups, the prokaryotes which consisted of bacteria and the eukaryotes which consisted of all the other higher organisms. Carl Woese divided organisms in three groups: Bacteria, Archaea and Eukaryotes. He concluded that Archaea are more similar to eukaryotes than to bacteria. Previously Archaea were thought to inhabit only hostile extreme places but now they have also been discovered in other less hostile environment.

Archaea are similar to bacteria when it comes to morphology. But the process of translation and transcription is significantly different from bacteria and resembles eukaryotes more. Their cell membrane have unique ether linked lipids for more stability and they have some unique metabolic pathways like methanogenesis.

If there is a logarithmic relationship between stimulus intensity and action potential frequency in sensory neurons, how much wi
frez [133]

Answer:

The action potential rate will be doubled

Explanation:

The logarithm of a number for a given base is the power to which the base must be raised to give the number. Logarithm of a number can be in different bases. The base of common logarithm is the base 10.

For example, logarithm of 1000 to base 10 is 3 because 10 raised to power 3 equals 1000

Log₁₀1000 = 3 since 10³ = 1000

Therefore, if there is a logarithmic relationship between stimulus intensity and action potential frequency in sensory neurons and the stimulus intensity increases by 100, the action potential rate will increase thus:

Log₁₀100 = 2

Therefore, the action potential rate will be doubled

If you are to conduct a DNA analysis using a blood sample which of the blood components will you use
sleet_krkn [62]
<h2>Question:- </h2>

If you are to conduct a DNA analysis using a blood sample which of the blood components will you use

<h2>Options :- </h2>

1.) Red Blood Cells

2.) White Blood Cells

3.) Plasma

4.) Platelets

<h2>Answer:- </h2>

Option 2.) White Blood Cells

<h2>Explanation:- </h2>
  1. Red Blood Cell(RBC) , Plasma , Platelets lack DNA
  2. White Blood Cell (WBC ) only have DNA
  3. RBC lack nucleus to make space for O2 as the work is to carry O2 with help of hemoglobin
  4. Platelets are the cell fragments of the large cells they help in clotting so too lack nucleus
  5. Plasma is the fluid part of the blood. so it contain water in its most part and too lack DNA bez plasma don't contain any cells
  6. WBC are the only cells which have well defined nucleus with DNA in above mentioned options
