Answer:
A cell that has duplicated chromosome cannot be in<u> G1 phase.</u>
Explanation:
- G1, G2 and S phase are the divisions of the interphase i.e. the resting phase of the cell cycle.
- A cell cycle has two phases; interphase and M-phase.
- During interphase the cell grows and in M-phase it divides.
- G1 is the Gap between the M-phase and the S-phase.
- G2 is the gap between the S phase and M phase.
- DNA replication is confined to the S part of interphase.
- Since G1 phase comes before the S phase , we can say that a cell that has duplicated chromosome cannot be in G1 phase.
Energy doesn't mean it's necessarily available to do work. energy exists in several forms such as heat, kinetic or mechanical energy, light, potential energy, and electrical energy. (etc.)
Answer:A
Explanation:<em>The core is a solid in the middle and molten on top of it</em>
Answer:
By osmosis, and osmosis is passive transport.
Explanation:
In a cell, water always enters by the process of osmosis no matters the wall is hydrophobic, hyrophillic, semi - permeable.

<h3>Answer:</h3>
The Fluid Mosaic Model declares that membranes are formed of a Phospholipid Bilayer with several protein molecules drifting about inside it. The ‘Fluid’ section describes how any components of the membrane can run nearby loosely if they are not connected to different components of the cell. The ‘mosaic’ section explains the ‘patchwork’ of proteins that are detected in the Phospholipid Bilayer.
<h3>Explanation:</h3>
There is a lipid bilayer in which the protein molecules are embedded. The lipid bilayer gives fluidity and elasticity to the membrane. Carbohydrates are also found in a cell membrane. The plasma membrane is said to be two-dimensional structure or liquid we can say which does not allow the lateral diffusion of membrane components. The plasma membrane has the texture of vegetable oil at body temperature, because of which the proteins and other substances move across it. That's why the plasma membrane is described as using the fluid-mosaic model.
