"CRISPR" stands for Clustered Regularly Interspaced Short Palindromic Repeats, which are the hallmark of a bacterial defense system that forms the basis for CRISPR-Cas9 genome editing technology. In the field of genome engineering, the term "CRISPR" or "CRISPR-Cas9" is often used loosely to refer to the various CRISPR-Cas9 and -CPF1, (and other) systems that can be programmed to target specific stretches of genetic code and to edit DNA at precise locations, as well as for other purposes, such as for new diagnostic tools. How can this tool be used to alter genes in various organisms?
Answer:
by designing short guide RNAs (sgRNAs) customized to target genes of interest in the cells of these species
Explanation:
The CRISPR-Cas9 editing system is a versatile and powerful genome engineering tool for editing genomes, which can be directed to alter almost any DNA sequence in order to modify gene function. This system consists of an endonuclease protein (Cas 9) that cuts DNA at specific sites guided by a short guide RNA (sgRNA), which binds by base complementarity to the target sequence. This sgRNA must be designed with efficiency and specificity to target genes of interest. In consequence, the CRISPR-Cas9 genome editing system produces DNA double-strand breaks which may be repaired by 1- error-prone nonhomologous end joining (NHEJ) or 2-homology-directed repair (HDR) DNA repair pathways. According to the DNA repair pathway that has been activated, it is possible to trigger genetic modifications in the cells of different species (i.e., plant cells, animal cells, human cells, etc).

A: Amino acid sequence
B: Dietary preferences
C: Habitat requirements
D: Social group interactions
Answer:
A
Explanation:
Studying amino acid sequences would provide the best evidence that two organisms share a common ancestor.
Amino acid sequence is a series of bases with different letters usually four(A T C G or U) this letter contains information of an individual when translated.
The amino acid sequence of 2 or more individuals can be compare to each other through the process called Blasting using a tool called Blast
Blast generates alignments or similarities between a amino acid or protein sequence.For organisms that are phylogenetically close i.e related by an ancestor, there will be similarities between their DNA sequences when compared. The amino acid sequence of an individual contains the information of the individual and it is unique for each individual.
Hence, amino acids sequence provides the best evidence of organisms sharing a common ancestor.

A 100 kg box is initially at rest on a level surface. One 10 N force acts on the box , directed toward the right. A second 10 N force acts simultaneously on the box , directed toward the left , as shown.
Since 10 N forces are acting from both sides, these are balanced forces and the box will not move because balanced forces are acting on it. So the correct option is D.
What are balanced forces?Forces that are equal in magnitude and opposing in direction are said to be balanced forces. Equilibrium is seen as a condition of balanced forces. There is no shift in direction when the forces are in balance.
Balanced combined forces have always been equal to zero. These are vectors for merging. Balance forces cannot alter an object's momentum or direction.
An item is kept traveling at a constant speed by a balanced force. In it, Newton's First Law of Motion is explained. A good illustration of a balanced force is a book on the table. The normal force (support force) of the table balances out the weight of the book. The two forces are exactly equal and opposed to one another.
While forces that are balanced can keep an item at rest or move at a steady speed, unequal forces can cause things to accelerate.
Therefore the correct option is D.

The statement that best describes photosynthesis is statement d. As it converts carbon dioxide to glucose and oxygen.
Photosynthesis uses light energy to convert carbon dioxide and water to glucose and oxygen.During photosynthesis, plants, algae, and some bacteria convert light energy into chemical energy, stored in the bonds of glucose molecules.
The process involves the absorption of light by pigments called chlorophyll, which are present in the chloroplasts of plant cells and other photosynthetic organisms. Chlorophyll uses the light energy to drive the conversion of carbon dioxide and water into glucose and oxygen in a process called the Calvin cycle.

explain how darwin's journey to the galapagos islands contributed to his creation of the theory of evolutions.
Explanation:
During his visit to the islands, Darwin noted that the unique creatures were similar from island to island, but perfectly adapted to their environments which led him to ponder the origin of the islands' inhabitants.
Among those that struck Darwin so greatly were the finches that are now named in his honor. Darwin would later base some of his thought from the supposing that these finches were all descendents of the same lineage.

in which direction do particles in a solution move during passive transport
During the passive transport, the particles move from a higher concentration to a lower concentration without the need for energy expenditure or spending. The passive transport is seen in the cell too.
What is the importance of the different types of transportation?In the cell, different types of transport are seen, such as active transport and passive transport; in active transport, energy is used, while energy is not used in passive transport. The movement of molecules across the cell plasma membrane is important because it allows cells to get rid of unwanted molecules. Passive transport does not require energy, and many nonpolar small molecules and gases can cross the lipid plasma membrane barrier and go into and out of the cell while, in this passive transport process, they save the cell's energy.
Hence, during the passive transport, the particles move from a higher concentration to a lower concentration without the need for energy expenditure or spending.

A two-word name for organisms where the word is the genus and the second word is the species
Explanation:
Binomial nomenclature is the system biologists use to name species of living beings. When we translate this term, we get the two-name naming system. This tells us a lot about how species are named - their name consists of two components. The first component is the name of the genus the species belongs to and the second is the name of the species. For example, the scientific name used for cats is Felis catus. Felis is the genus and the species is catus.

Which best describes what occurred?
- Continental shifting resulted in a tsunami.
- Continental shifting resulted in a volcano erupting.
- Tidal activity in the subduction zone caused a tsunami.
- Tidal activity in the subduction zone caused a volcano to erupt.
Answer:
An earthquake occurred three hundred miles off the shoreline, and massive flooding occurred on land as a result. Which best describes what occurred? Continental shifting resulted in a tsunami.
Explanation:
The best thing that describes the scenario that occurred is tidal activity in the subduction zone caused a tsunami. The correct option is C.
What is tsunami?The violent breaking of rock during an earthquake releases energy that travels through the earth in the form of resonance known as seismic waves.
These seismic waves radiate from the hypocenter in all directions, becoming weaker as they travel further away from the hypocenter.
Tsunamis are a series of large waves with extremely long wavelengths and periods that are usually caused by a violent, impulsive undersea disturbance or activity near the coast or in the ocean.
When a large earthquake ruptures, the faulting can cause vertical slip large enough to disturb the overlying ocean, causing a tsunami to travel in all directions.
Thus, the correct option is C.
