Changes in the shape of a cell usually involve a reorganization of the
cytoskeleton.
Cytoskeleton is an interwind filamentous network that mainly keeps and mantains the shape as well as internal organization.
- Hence reorganization is also done with the help of the cytoskeleton.
- Extracellular matrix mainly helps the cell to keep it together.
- Transporter proteins mainly act as a catalyzing agent for various purposes.
- Nucleus is just a genetic material carrying an organelle that regulates the activities of cells.

¿What is the Kingdom Plantae?
It is one that is composed of multicellular, eukaryotic, autotrophic, anaerobic and immobile organisms whose reproduction is sexual or asexual.
They are classified in :-
I hope I've helped : )
The best answer is A.
The lytic cycle is considered the main cycle in viral replication. Once the viral DNA enters the cell, it transcribes itself into the host cell's messenger RNAs and uses them to direct the ribosomes.
The host cell's DNA is destroyed and the virus takes over the cell's metabolic activity and begins to use the cell's energy for its own propagation and within a short while, when the cell gets overcrowded with the viral progeny, the original virus releases enzymes to break the cell wall. The cell wall bursts. This process is called lysis. The new viruses are then released.
In active transport, materials move from an area of high concentration to an area of lower concentration (goes down the concentration gradient) and it requires or uses energy in the form of ATP (adenosine triphosphate)
Rock A = It is a metamorphic rock that experienced tremendous heat and pressure due to massive, moving tectonic plates.
Metamorphic rocks are rocks that have been somewhat squished and transformed by heat and pressure. These rocks often have different layers as the rocks go through pressure and are literally look like rocks that have been piled up and then stuck together. The best indicator of this rock being a metamorphic rock is the wavy elongated stripes. The stripes are created from the different rock elements being pressed together over time.
Rock B = It is a sedimentary rock made primarily from lithification of organic material.
Sedimentary rocks are rocks that have been formed by different substances that come together due to the different weather conditions. The best indicator of this being a sedimentary rock is how the rock came together and looks like a bunch of shells were glued together.
Rock C = It is an igneous rock that was formed above Earth’s surface.
Most igneous rocks have smooth outer layers. These rocks are often made with solidified magma from volcanoes. The best indicator of this being an igneous rock is the indication of it being a solidified piece of magma.
