A detergent works by solubulizing grease and forming an emulsion of the grease with water.
A detergent is commonly used as a cleaning agent. Every detergent consists of a hydrophobic tail and a hydrophilic head. The hydrophilic head is capable of interaction with water hence the detergent can dissolve in water. Its hydrophobic tail is capable of interaction with grease.
A detergent works by agglomerating its molecules into micelles which dissolve the grease. Mechanic scrubbing completely eliminates the grease creating an emulsion with water.

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.

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.

All skeletal systems provide support to organisms, but only two types are hard. Which lists the two hard skeletons?
Answer: A skeleton is a structural frame that supports an animal body.
There are two major types of skeletons: solid and fluid.
Exoskeletons are external, and are found in many invertebrates; they enclose and protect the soft tissues and organs of the body.
Explanation: HOPE IT HEPLS
The one that lists the two hard skeleton is endoskeleton and exoskeleton.
What is skeleton?The scaffolding that holds up vertebrate creatures' soft tissues and shields many of their internal organs.
A human adult has 206 bones in their skeleton. These include the vertebrae in the spine, the ribs, the arms, and the legs.
Bones are composed of specialised bone cells and connective tissue that has been strengthened with calcium. The bone marrow that makes blood cells is also found in the majority of bones.
Exoskeletons are hard external skeletons that protect an organism's exterior while allowing for mobility via muscles attached internally.
An endoskeleton is a hard, mineralized internal skeleton that also allows mobility by attaching to muscles.
Thus, the answer is endoskeleton and exoskeleton.

If the DNA sequence for a gene is known, then
Answer:
Determining the order of the nucleotides within a gene is known as DNA sequencing. The earliest DNA sequencing methods were time consuming, but a major breakthrough came in 1975 with the development of the process called Sanger sequencing. Sanger sequencing is named after English biochemist Frederick Sanger, and it is sometimes also referred to as chain-termination sequencing or dideoxy sequencing. Some 25 years after its creation, the Sanger method was used to sequence the human genome, and, with the addition of many technological improvements and modifications, it remains an important method in laboratories across the world today.

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.
