How are the blunt and sharp pipettes
sveta [45]

Answer:

During the process of the type of cloning known as Somatic Cell Nuclear Transfer (SCNT), once the nucleus is removed from the egg cell, blunt and sharp pipette both are used. The purpose of the blunt pipette is to hold the egg cell in position whereas the sharp pipette penetrates the cell to take the nucleus out by sucking it - a process known as "enucleation". This nucleus is discarded. Rather, this nucleus is replaced by a nucleus taken out from a somatic cell (same way as described before) of the same organism.

Hope that answers the question, have a great day!

Which statement about control of glycogen metabolism is INCORRECT? Which statement about control of glycogen metabolism is INCOR
GuDViN [60]

Answer:

Glycogen synthase is phosphorylated at only one site.

Explanation:

Glycogen synthase has multiple sites where phosphorylation can occur. Glycogen synthase may have 9 or more sites where it can be phosphorylated as a result of which it's activity is down regulated. It simply means that the regulation of this enzyme does not occur through binary on/off switching, in fact it's activity is modulated over a wide range in response to various signals.

In contrast to glycogen phosphorylase which gets activated when it is phosphorylated at it's serine residues, glycogen synthase gets inactivated by phosphorylation.

As soon as another enzyme GSK3β phosphorylates glycogen synthase, it gets inactivated as a result of which glycogen synthesis halts in the liver.

Please help asap (photosynthesis)
kirza4 [7]

Answer:

ATP and NADPH

Explanation:

Photosynthesis starts out using the energy from sunlight to get things started, but it ends with the dark reactions, which don't need sunshine to complete sugar production. In the Calvin cycle, ATP and NADPH from the light reactions are used to produce sugars.  

So, the correct option is, 'ATP and NADPH'.

Ulleksa [173]
Are you talking about like isotonic and hypertonic or are you asking what hypotonic solution means if it was hypotonic the cell would be expanding if it was hypertonic the cell would be shrinking which means more molecules would be going inward in the cell if it was hypertonic if it was hypotonic the molecules would go more on the outside in the water would come in
