Summarize at least 2 advantages of CRISPR.
CRISPR is simple and powerful compared to the rest of technologies used for editing genome. It is simple because it has the ability to point the definite DNA sequences which is facilitated by an easy to synthesize regulated strand of RNA. It is powerful because it let on an immediate target and remove and improve all deterioted DNA sequence present in a gene.
Answer: See Below
Explanation:
1. CRISPR utilizes a guide RNA (gRNA) that directs the function of a CRISPR protein effector to a specific target gene of choice, providing a versatile programmable platform. The targeting sequence of the gRNA is ~20bp therefore off-target genome editing is less common making it advantageous over most other restriction endonucleases.
2. CRISPR has increased versatility in many aspects and allows for a wide variety of applications in terms of genome editing. For example, The nickase version of the Cas protein induces only a single stranded cut thus opening up opportunities for altered editing. The Cas12a or Cpf1 version of the Cas protein cuts to form 5' sticky ends. And finally for the last example, the Cas protein has been bound to a reverse transcriptase and has shown efficacy in a technique called "Prime Editing" which has an altered gRNA that provides a primer binding site and template for full base insertions, deletions, and combinations of the two.
how are speciation and niches interconnected concepts?
Specification and niches are related ideas:
The process by which populations divide into distinct species is known as speciation. Cladogenesis describes the division of lineages as opposed to anagenesis, or phyletic evolution within lineages. Biologist Orator F. Cook used it for the first time in 1906.
A species' niche is its role within the ecosystem. In other terms, an organism's "niche" is how it "earns a living." A niche will include an organism's role in the movement of energy across the ecosystem.
Closely related species (such as sister taxa) frequently occupy incredibly diverse ecological niches and may have noticeably different geographic ranges despite sharing a shared evolutionary history.
The concept of "budding speciation" is one method that could help to explain how disparities in niche and dispersion features might swiftly evolve. "Budding speciation" is the process through which new species appear as initially small, colonizing colonies that reach reproductive isolation. This theory of species origin predicts that distributions of sister species should be noticeably lopsided at the time of speciation.

Answer:
C. Atom Y
Explanation:
when calculating charge, the "Number of Neutrons" doesn't matter because neutrons have no charge. (so you can ignore the neutrons section for this question)
also, protons have a positive charge, and electrons have a negative charge
to solve this problem, add the charges of the protons and neutrons together to see if the number ends up positive (because question is looking for positive charge)
for Atom W: [tex]3+(-3) = 0[/tex], so no, this isn't the answer. 0 is neutral charge
for Atom X: [tex]53 + (-53) = 0[/tex], this isn't the answer either. 0 is neutral charge
for Atom Z: [tex]1+(-1)=0[/tex], nope, 0 is neutral charge
for Atom Y: [tex]55+(-54) = 1[/tex], yay this is it, 1 is positive which indicates positive charge.
therefore, C. Atom Y is the answer
Use what you know about fossils to choose the correct answers from the drop-down menus to complete each statement.
I know about fossils that Fossils provide a record of animals that are, or are no longer living which is the correct answer from the dropdown menu.
The history of life as recorded by fossils, which are the remains or imprints of species from past geological eras preserved in sedimentary rock, is known as the fossil record. Continents that were once together must have been together in the geological past, according to fossils of the same genus or species. The dead and organic remains of extinct species that were buried deep in the earth millions of years ago are known as fossils. It is defined in a more straightforward manner as the remains or evidence of plants and animals that once lived in the past.
When an organism or fossil demonstrates a process of steady change over time, it is said to have undergone an evolution. Extinction, on the other hand, is the event in which species vanish from the ecosystem as a result of any method, such as habitat destruction.

The production of APP in a neuron. APP is represented by the triangles.
Using Figure 1, label the following: neuron, nucleus, rough ER, Golgi, transport vesicles, APP, and exocytosis.
1) Labelled image in the attached files. 2) mRNA synthesis occurs in the nucleus. Protein synthesis begins in the cytoplasm and ends in the RER, where folding and the first glycosylation stage occur. In the Golgi complex, glycosylation is over, proteins are packaged into vesicles and sent to the membrane, from where they are released by exocytosis.
What is protein syntesis?Protein synthesis is the process through which new proteinic molecules are porduced. It involves transcription, translation, and maturation.
Transcription ⇒ mRNA synthesis
The first step before protein synthesis begins is to synthesize messenger RNA, mRNA. This is the coping process of the DNA section for the desired protein, and it happens in the nucleus.Translation ⇒ Cytoplasm stage
Translation takes place when the formed mRNA moves to the cytoplasm through the nucleus membrane pores.
Once in the cytoplasm, mRNA meets a ribosome, which can be found in the rough endoplasmic reticulum or floating in the cytosol.
While the ribosome reads mRNA strain, tRNA adds the correct amino acids to build the polypeptide.
Maturation process
⇒ Endoplasmic Reticulum Stage
Some proteins are destined for exportation. Their synthesis starts in the cytoplasm but finishes in the Rough endoplasmic reticulum.
When the ribosome and the growing molecule reach the RER, the synthesizing protein keeps enlarging forward the reticulum lumen. When the new polypeptide synthesis is complete, it is released into the reticulum lumen.
The endoplasmic reticulum is in charge of protein folding, maturation, and transport, especially those destined for secretion. It produces the latest protein modifications after transduction and initiates the glycosylation process.
⇒ Golgi complex stage
Once the protein synthesis in the endoplasmic reticulum is over, these molecules are packaged into vesicles and sent to the Golgi complex.
In the Golgi complex, proteins suffer their final association with carbohydrates and lipids to originate glycoproteins and glycolipids.
⇒ Destiny stage
Glycoproteins and glycolipids are packaged again into new vesicles that drive them to their final destiny.
Exportation proteins move forwared to the membrane within vesicles. Through exocytosis events, these molecules are released.
