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.

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.

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.

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.

Answer:
It would depend if it is like a bird or something not if it is:
Explanation:
Yes their offspring could have wings if it is both of them have a recessive gene of wings if they do not have a recessive gene for wings then they cannot.
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.

the number of chromosomes being copied
the types of cells near the site
the types of cells near the site
the amount of time a cell takes to replicate DNA
the amount of time a cell takes to replicate DNA
the ability to reverse terminal differentiation
the ability to reverse terminal differentiation
Answer:
i am researching the answer give me a minute
Explanation:
In complex organisms gene expression can be influenced by the type of cells near the site because different cells represent the different structures of the protein, hence option b is correct.
What is gene expression in a complex organism?Expressivity may be impacted by a number of elements, such as genetic makeup, exposure to dangerous chemicals, other environmental effects, and age.
Different cell types produce different levels of gene expression which creates different cell structures with different functions.
The environment, comprising the external environment in which an organism is placed or develops as well as the organism's internal environment, metabolism, can affect how genes are expressed in an organism.
Therefore in complex organisms, a major factor is cell type influences gene expression, hence option b is correct.

An urban area can reduce air pollution if more people give up using cars individually for buses or trains.
True
False
Answer: It is TRUE! Hope this helped :)
Explanation: If more people took buses or trains, then there wouldn't be so much air pollution. For example if 5 people chose to take a bus or train to wherever they are going, that's 5 less cars causing air pollution! :)

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.
