What is the process of genome editing?
Genome editing (also called gene editing) is a group of technologies that give scientists the ability to change an organism's DNA.
The list of the process of genome editing:
1. The target DNA sequence.
2. Sequence with correct gene sequence.
3. The ability to remove the mutated gene sequence.
These technologies allow genetic material to be added, removed, or altered at particular locations in the genome.

Cell theory will not ever become the law of cells because cells undergo changes as mutations occur within them, and developing anything beyond cell theory would be impractical.
What do you mean by Cell theory?Cell theory may be defined as a theory given by M.J. Schleiden and T Schwann which states that all living organisms are made up of cells which are the smallest unit of all living entities.
It is only due to mutations, cell changes its identity and properties randomly. Hence, it seems very tough for scientists to analyze all the mutations in the cell.
Therefore, cell theory will not ever become the law of cells because cells undergo changes as mutations occur within them, and developing anything beyond cell theory would be impractical.

Which example is indirect evidence used to study Earth’s interior?
composition of minerals in a rock
age of a rock from within Earth
location of an earthquake’s epicenter
texture of different core samples
Answer:
location of an earthquake’s epicenter
An indirect evidence is one which is used to infer or support the clause. The location of an earthquake’s epicenter can be used to study Earth’s interior.
Three main layers make up the Earth. The crust, mantle, and core are those. Additionally, since the earth's interior cannot be directly studied, the composition of rocks can be understood from direct evidence.
Seismic waves aid in comprehending circumstantial evidence. The energy that passes through the various layers of the earth is carried by seismic waves. Landslides, earthquakes, and volcanoes are some of the causes. The direction of the seismic wave, as well as the location of the earth's epicenter, can be determined by analyzing several seismographs.
Therefore, studying the location of an earthquake’s epicenter would give an idea of Earth’s interior. The correct answer is option C.

Which of these is not a direct function of mitosis in humans?
O development from embryo to adult
O reproduction to produce the next generation
O repair of damaged tissue
O growth
Answer:
O reproduction to produce the next generation
Explanation:
Meiosis is responsible to reproduction (not mitosis). The rest of options are for mitosis.
The one that is not a direct function of mitosis is reproduction to produce the next generation. The correct option is B.
What is mitosis?Mitosis is a type of cell division in which one cell (the mother) divides to produce two new genetically identical cells (the daughters).
Mitosis is the process by which the DNA of the cell's nucleus is divided into two equal sets of chromosomes in the context of the cell cycle.
Meiosis is the process by which egg and sperm cells are formed. Mitosis is a necessary process for life.
Meiosis is a type of cell division that produces four gamete cells while reducing the number of chromosomes in the parent cell by half.
This process is necessary for the production of egg and sperm cells for reproduction.
Thus, the correct option is B.

It is true that rivers and streams are biodiverse ecosystems that are sensitive to change. Details about rivers and streams can be found below.
What is river and stream?A river is a large and often winding stream which drains a land mass, carrying water down from higher areas to a lower point, oftentimes ending in another body of water, such as an ocean or in an inland sea.
On the other hand, a stream is a small river or a body of moving water confined by banks.
Rivers and streams are both freshwater ecosystems, hence, tend to respond to changes in their environment caused by anthropogenic activities.

the second law of thermodynamics states that?
Answer:
"As energy is transferred or transformed, more and more of it is wasted."
Explanation:
Answer:
"As energy is transferred or transformed, more and more of it is wasted."
In this case the second law of thermodynamics (in the simplified form presented here) says that no matter what process takes place inside the container, its entropy must increase or remain the same in the limit of a reversible process...
Explanation:
The second law of thermodynamics states that as energy is transferred or transformed, more and more of it is wasted. It's one of the four laws of thermodynamics, which describe the relationships between thermal energy, or heat, and other forms of energy, and how energy affects matter...
The second law of thermodynamics says that when energy changes from one form to another form, or matter moves freely, entropy (disorder) in a closed system increases. Differences in temperature, pressure, and density tend to even out horizontally after a while...
The second law of thermodynamics describes the nature of processes and chemical reactions as follows: processes occur spontaneously if and only if by their process, the entropy change in the universe, is greater than or equal to zero…
Second law of thermodynamics:Statement,examples and applications. The second law of thermodynamics states that heat can flow spontaneously from a hot object to a cold object; heat will not flow spontaneously from a cold object to a hot object. Carnot engine, heat engine are some examples of second law of thermodynamics .....
The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object.
Why is the second law of thermodynamics so important? Second law of thermodynamics is very important because it talks about entropy and as we have discussed, 'entropy dictates whether or not a process or a reaction is going to be spontaneous'...
His formulation of the second law, which was published in German in 1854, is known as the Clausius statement: Heat can never pass from a colder to a warmer body without some other change, connected therewith, occurring at the same time. The statement by Clausius uses the concept of 'passage of heat'...
“The first law of thermodynamics also known as the law of conservation of energy states that energy can neither be created nor destroyed, but it can be changed from one form to another.” “The second law of thermodynamics states that the entropy in an isolated system always increases.”
2. what is the trend between 20-30 years in the kelp population? explain.
The trend between 20-30 years in the kelp population is that it is reducing due to sea urchins eating kelp and clipping the bottoms, hence, stopping kelp from regrowing.
What is the trend in the Kelp population?Kelp is a form of giant seaweed found in ocean floors.
Kelp serve as food for certain sea animals such as sea urchins.
However, due to increasing number of sea urchins and increase in environmental pressures, the Kelp population reduced in the last 20 to 30 years.
Therefore, the trend between 20-30 years in the kelp population is that it is going down due to sea urchins eating kelp and clipping the bottoms, hence, stopping kelp from regrowing.
