Answer: Endoplasmic Reticulum
Explanation:
The Endoplasmic Reticulum is a network of interconnecting membrane enclosing channels that are continuous from outer outer nuclear envelope to plasma membrane. ER is classified into rough and smooth varieties.
The ER is very prominent in the cell activity synthesizing proteins e.g glycoproteins, lipoproteins and immunoglobins
Answer:
The enzyme that is responsible for this is the cyclin dependent kinase subunit of mpf
Explanation:
This enzyme is also known as cyclin dependent kinase subunit, CDKs. they are protein kinases and can function as cell cycle regulators. They have the power to modify different protein substrates that are useful for the progression of cell cycle. CDKs are inhibitors hence stathmin is inactivated by phosphorylation. They help to control cell divisions. DNA should not be damaged for cell to move from G₁ to the S phase.
C) Valence electrons may be lost or gained by an atom when bonding occurs with another atom
Lysosomes absorb and eat food. When a tadpole turns into a frog, the lysosomes consume the tail since the tail is not needed and is therefore seen as food for the lysosomes.
