The CRISPR-Cas system is a genome engineering tool to edit the genome of any species. The crRNA is a sequence complementary to the target DNA of this genome editing system.
The CRISPR-Cas genome editing system is a recently developed genome engineering tool, which can be used to edit the genome of virtually any species.
This genome editing system consists of a nuclease (Cas) protein that cuts the DNA at the targeted regions, and a single guide RNA (sgRNA), which contains a crRNA (17-20 nt) sequence complementary to the target DNA.
In consequence, the sgRNA guides to the Cas protein in order to cleave the genome at targeted nucleotide sequences.

________________________ happen when pairs of bonded bases in a double strand of DNA get replaced with different pairs.
_________________________ happen when extra base pairs are included in an existing DNA sequence.
_________________________ happen when base pairs in an existing DNA molecule get removed from it.
Fill in the blanks correctly
Answer:
Explanation:
A base pair is two chemical bases bonded to one another forming a "rung of the DNA ladder." The DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.

Is phrenology an example of science or
pseudoscience? Explain your answer.
Answer:
Pseudoscience
Explanation:
Phrenology is an example of pseudoscience. It is the belief that studying the conformation of the skull reveals the character traits and mental faculties of an individual, a conclusion not at all rooted in fact but nevertheless studied and pursued as such thereby giving a false sense of being based in scientific methods.
Answer:
Pseudoscience
Explanation:
Phrenology is an example of pseudoscience because Gall held beliefs and ignored any information that didn't align with his beliefs. This is a direct example of Gall using pseudoscience and testing his hypothesis with bias through his belief.

What is the mechanism by which the secretion of a hormone is followed by travel to a distant target cell
Answer:
induction or repression of enzymes
Explanation:
Hormones are chemical messengers which are secreted by endocrine glands and regulate the rate of existing activities, usually through the induction or repression of enzymes within distant target cells via the endocrine system. They travel in the bloodstream, having slower, but longer lasting effect and are effective in small quantities.
hope it helps
The mechanism by which the secretion of a hormone is followed by travel to a distant target cell is primarily through the bloodstream. Once in the bloodstream, hormones are carried throughout the body, allowing them to reach their target cells or tissues.
Hormones are usually released in small amounts but have potent effects on target cells. The binding of a hormone to its specific receptor triggers signaling pathways within the target cell, leading to changes in cellular function or gene expression.
The travel of hormones through the bloodstream ensures their widespread distribution and enables them to reach distant target cells located in different organs or tissues.
This mechanism allows hormones to exert their regulatory effects on various physiological processes, including growth and development, metabolism, reproduction, and homeostasis.

Answer:
Statements thar are true:
Some organisms have phenotypes that make them better increase chances of reproduction.
Natural selection continues to occur even today
Phenotypes found In the most successful members of a species become the most prevalent after several generations.
Explanation:
It is not true that all organisms must compete for survival, sometimes the conditions are good and there is enough food or good climate conditions and that makes no need of competition an increase in the individuals of the species.
Animals undergo natural selection, this is a random natural phenomenon that can make plants and animals adapt better or worse to the enviromental conditions. This cause that the beneficiaries can adapt, survive and reproduce and became the most prevalent after generations.
Mutations are not phenomen that occur because the living being needs it, but rather they are phenomenon that occur at random at any time and determine the possibility of survival.
A decrease in food availability will do the contrary, decrease the variation in a population because it makes that only those who manage to adapt to eat another food survive, for example.
