what is the function of circuit breakers and fuses?
Answer:
Fuses and Circuit Breakers both serve the same purpose – which is to protect electrical circuits by preventing overloads that can cause fires. They both interrupt the flow of electricity, but in very different ways from each other. While a fuse is made of a piece of metal that melts when overheated, circuit breakers on the other hand, have internal switch mechanisms that can be tripped by an unsafe surge of electricity.
Fuses can be quicker for interrupting the flow of power, but when they melt they must be replaced; circuit breakers on the other hand just need to be reset. When comparing the two, we’ll take a look at some of the major advantages and disadvantages between fuses and circuit breakers to distinguish between them.

Organisms require a variety of chemical nutrients, such as ______, which are components of proteins, nucleic acids, and ATP.
Organisms require a variety of chemical nutrients, such as NITROGENOUS, which are components of proteins, nucleic acids, and ATP. It is an essential element for life.
Nucleic acids, either DNA or RNA, contain nitrogen in the nitrogen bases of their nucleotides (i.e., Adenine, Guanine, Cytosine and Thymine, Uracil).
Adenosine triphosphate (ATP), the energy coin of the cell, contains nitrogen in its Thymine nitrogen base.
Finally, proteins are made of amino acids, whose building blocks are carbon, hydrogen, oxygen and nitrogen atoms.

B. a species that failed to adapt to changes to its environment
C. a species that is almost gone because of the excessive pollution in its habitat
D. a species that has become too populous and threatens the survival other of species
Answer: I believe it's C
Explanation: edg 2021
The correct option is C.
Why do they call it a right whale?
The right whale got its name because it was the right whale to hunt—it moved slowly and would float after being killed. A North Atlantic right whale mother and calf were spotted off the U.S. southern coast by NOAA researchers during the 2020 breeding season.
How rare is a right whale?North Atlantic right whales have been listed as endangered under the Endangered Species Act since 1970. The latest preliminary estimate suggests there are fewer than 350 remainings, with fewer than 100 breeding females. The number of new calves born in recent years has been below average.

The primary function of the stomach is which of the following?
To serve a holding tank is a primary function of the stomach.
What is Stomach?
The J-shaped organ that digests food is the stomach. It generates acids and enzymes, which are molecules that cause chemical reactions (digestive juices).
Food is broken down by this mixture of enzymes and digestive juices so that it may move to our small intestine.
A portion of the gastrointestinal (GI) tract includes your stomach. Your mouth is the beginning of the GI tract, which is a long tube. The stool (poop) exits your body through your anus. A crucial component of your digestive system is the GI tract.
Therefore, To serve a holding tank is a primary function of the stomach.

What is the degree of the polynomial 3x^5-6x^2+5x?
A ) 8
B ) 7
C ) 2
D ) 5
Answer:
D.5
Explanation:
i took the test trust meThe degree of the polynomial 3x^5 - 6x^2 + 5x is 5, so the answer is option D.
A polynomial is a type of algebraic expression that consists of variables, coefficients, and exponents.
There can be one or more terms in a polynomial, and the degree of the polynomial is determined by the highest power of the variable present in it.
For example, the polynomial 3x^2 + 4x + 5 has a degree of 2 since the highest power of the variable (x) is 2. In the given polynomial 3x^5 - 6x^2 + 5x, the highest power of the variable is 5, which means that the degree of the polynomial is 5.
Hence, the correct answer is option D.

Describe the structure and bonding of gold
Answer:
structure
The arrangement of atoms in gold follows what's called a "face centred cubic" (fcc) structure. Put simply, the atoms in gold form cubes, with an atom at each of the corners, and another atom in the centre of each of the faces (you can see what this looks like in the image below).
bonding
Silver, iron, platinum, gold, and copper all form metallic bonds. Unlike covalent bonding, metallic bonding is non-directional. The strong bond consists of positively charged metal atoms in fixed positions, surrounded by delocalized electrons.
Explanation:
Gold's atoms are face-centered cubic (fcc) and has metallic bonding in it's structure.
What is the bonding and structure of gold?Because a cloud of electrons holds the atomic nuclei of gold together, gold is soft. Instead of having a set of electrons allocated to one nucleus, this cloud floats through the gold framework. Metallic bonds are the forces that exist between the nuclei and the electron cloud.
In gold, atoms are arranged in a configuration known as a "face-centered cubic" (fcc) structure. Simply put, the gold's atoms take the shape of cubes with one at each of their four corners and another in the middle of each of their six faces.

Answer:
Option 3.
totipotent stem cells → pluripotent stem cells → multipotent stem cells → neuron
Explanation:
The development of the various stages of stem cells in the embryonic stage is described here:Totipotent stem cells: Right after the mitosis of the zygote which results in the formation of two identical daughter cells, which are totipotent stem cells. Totipotent stem cells possess the ability to give rise to 220 different types of cells in the embryo including the placenta.Pluriopotent stem cells: These types of cells possess the ability to change into any type of cell in the body like blood, muscle, etc. It is formed at the embryonic stem cell stage.Multipotent stem cells: These stem cells have the ability to change into specialized cell such as forming different organs in the body. It occurs as the pluriopotent cell develops in the embryo.Neuron: As the multipotent cell has the ability to form a specialised cell it gives rise to the heart, lungs, liver, etc. including neurons.for more information:
