The answer is nucleus acids
Answer:
First law of thermodynamics is the conservation of energy states that energy is not created and not destroyed but only can be stored.
Thermodynamics second law states that total entropy of a system increases from lower to higher system and some of the energy is always wasted during the work done.
In the food chain plants are the producers which accept light energy and stored in the form of chemical energy and energy flow to the herbivores and higher trophic levels in the chemical form only and no new energy is created in between the chain (Fisrt law of thermodynamics). Heat is generated during respiration by plants and animals (wasted energy) and entropy also increases with the increase in level of the pyramid of energy (Second law of thermodynamics).
Answer:
I think you're referring to the Metaphase...
Explanation:
During Cell Division (or, rather before!) the DNA needs to be replicated. This normally is done by DNA Polymerase, and results in two identical double strands (the "Sister Chromatids".
These chromatids are held together at the Centromere, which will be the heart of the "X"-shape. After that the DNA is packed into Chromosomes by winding it around proteins called Histones. If I remember correctly there are 5 different Histones.
This "Zipping Up" makes the chromosomes more visible.
As the two sister chromatids are still connected, the result is the X-shaped Metaphase Chromosome....
We use cell membranes to treat disease because the cell membrane is one of the main barriers that pathogens need to overcome, hindering their replication.
<h3>What is the cell membrane?</h3>
The cell membrane is a thin lipoprotein film formed by phospholipids and proteins delimiting the cytoplasm of all types of cells. They prevent invading microorganisms from attaching to the cell and replicating.
Then, using the concepts of cell membrane, we can use them to prevent viral diseases from occurring since the virus cannot fix itself to replicate. So in this case, the cell membrane is one of the main barriers that pathogens need to overcome, hindering their replication.
