why is gmo modification different for plants and animals
In animals, a gene is inserted into an embryo, modifying the genome to manufacture the product of this new gene. In plants, a gene is injected into a single cell that is grown from a seed into a plant. This plant expresses the new gene in all its cells. The difference between GM and selective breeding.

Explanation:
new genes can be added to or replace the genes on a bacterial plasmid in a process known as __.
Answer:
Recombinant plasmid
Explanation:
Researchers can insert DNA fragments or genes into a plasmid vector, creating a so-called recombinant plasmid.
This plasmid can be introduced into a bacterium by way of the process called transformation.
Recombinant DNA is a molecule that comes from the artificial union of two DNA fragments, a recombinant plasmid is built with DNA fragments from different sources.
What is a recombinant plasmid?It is a molecule of deoxyribonucleic acid (DNA) whose replication is independent of the DNA chromosome.
Recombinant DNA is a process that occurs when the bacterial plasmid has the ability to add a foreign DNA fragment into its own genome.
Therefore, we can conclude that recombinant DNA is a molecule that comes from the artificial union of two DNA fragments, a recombinant plasmid is built with DNA fragments from different sources.

The complexes of electron transport chain complexes take up the electrons and pass their one electron to the another acceptor following redox reactions. The process is chemiosmosis carried out by electron chain complexes.
What is electron transport chain ?
Electron transport chain is the series of 4 protein complexes coupling redox reactions in order to create proton gradient and generate the gradient for the process called oxidative phosphorylation to create ATP.
To create ATP which is the energy currency of the cell via the oxidative phosphorylation through ATP synthase enzyme which is membrane bound.
Chemiosmosis deals with the process driven by generation of H gradient across the mitochondrial membrane.
Thus, the process is called chemiosmosis dealing with the proton gradient.

Cutting DNA with a particular restriction enzyme produces DNA fragments that can be separated by ________.
Cutting DNA with a particular restriction enzyme produces DNA fragments that can be separated by gel electrophoresis.
Gel electrophoresis is a technique commonly used in molecular biology to separate and analyze DNA fragments based on their size and charge.
During gel electrophoresis, the DNA fragments are loaded into wells on an agarose gel, which is a porous gel-like substance.
An electric field is applied across the gel, causing the negatively charged DNA fragments to migrate towards the positive electrode.
Since the gel acts as a sieve, smaller DNA fragments move through the gel more quickly than larger fragments.
As the DNA fragments move through the gel, they become separated into distinct bands according to their size. This allows researchers to visualize and analyze the DNA fragments based on their migration pattern.
By comparing the separated fragments to a DNA size marker, which contains DNA fragments of known sizes, the size of the original DNA fragments can be determined.
Gel electrophoresis is an essential tool in molecular biology for DNA fragment analysis, genetic mapping, and many other applications.

What happens when the CO2 reaches zero?
Answer:
The energy that is held at the Earth by the increased carbon dioxide does more than heat the air. So even if carbon emissions stopped completely right now, as the oceans catch up with the atmosphere, the Earth's temperature would rise about another 1.1F ( 0.6C ). Scientists refer to this as committed warming.
