I believe the answer is C. Zygote.
Explanation:
Hope this helps! ^^
Ans.
Memory cells of immune system are present in G0 phase, in which these cells are not activated or responding for a pathogen.
The cell-cycle is defined as the series of events that lead to DNA duplication and division of a cell to form daughter cells. The cell cycle is divided into interphase and M phase.
The interphase includes gap 1 (G 1) phase, S or synthesis phase, and gap 2 (G 2) phase, while M phase includes karyokinesis and cytokinesis.
The cells after M phase either goes for next cell division or G1 phase or for G 0 (gap 0) phase. The G0 phase is resting phase, in which cells show a quiescent state.
As memory cells are present in resting phase, till the next exposure of same antigen, these cells are in G0 phase of cell cycle.
Answer:
a. double-blind experiment
Explanation:
A double-blind study <em>is done when the participants and experimenters do not know who is receiving which treatment in order to prevent bias.</em> We can conclude this is the correct answer because the results are being shared anonymously.
I hope you find this information useful and interesting! Good luck!
Answer:
<em>Escherichia coli </em>- Facultative anaerobe
<em>Micrococcus luteus </em>- Obligate aerobe
<em>Clostridium sporogenes</em> - Obligate anaerobe
Explanation:
In simple terms, obligate aerobes are organisms that require oxygen to grow and metabolize molecules such as fats and sugars to produce energy. Many animals fall under this category. Other examples are <em>Mycobacterium tuberculosis </em>and <em>Micrococcus luteus</em>.
Facultative anaerobes are organisms (usually bacteria) that can grow both in the presence and absence of oxygen. The most example of this are the <em>Escherichia coli</em><em>.</em>
Obligate anaerobes are organisms (usually microorganisms) that cannot survive when exposed to normal atmospheric concentration of oxygen. Examples are <em>Clostridium sporogenes</em><em> </em>and <em>Clostridium botulinum.</em>
