In the bacterial CRISPR system, the crRNA performs which of the following functions?
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.

Variation in offspring is important in maintaining genetic diversity within a population . Which of the answer choices indicates a mechanism of introducing genetic variation in a population? Select all that apply.
A crossing over during meiosis B ) fertilization of an egg by a sperm
C) independent assortment during meiosis
D) mitosis producing two new daughter cells
E) binary fission resulting in two bacterial daughter cells
Answer:
A B and C
Explanation:
Crossing over breaks, exchanges and rejoins chromosomes at corresponding points so introduces genetic variation. Because of crossing over offspring has characters of both parents.
Also independent assortment means that during separation of the chromosomes in anaphase, any chromosome can pair up with another. So for example if we have one parent plant with yellow and wrinkled seeds and other one with green and round seeds, then the gene responsible for round seed can pair up with either of the genes responsible for yellow seeds or green seeds. Hence the characters of offspring differ from the parents, it can have yellow round seeds or yellow wrinkled seeds and so on.
Mitosis will only produce 2 daughter cells which are exactly like their parent cells and are also identical to each other. Binary fission is a form of Asexual reproduction so it does not involve shuffling of genes from 2 parents.
Because of fertilization of egg with a sperm the maternal genes and paternal genes mix together. So it also produces genetic variations.

Which type of tree harvesting increases the chances of forest renewal?
Clear cutting
Strip cutting
Selective cutting
Slash and burn
Select cutting allows uneven aged trees as a result, it's more natural, and provides more diversity although it is more expensive
- BRAINLIEST answerer
The type of tree harvesting that increases the chances of forest renewal is Selective cutting.
What is Selective cutting ?Selective cutting exists as the cutting down of designated trees in a forest so that the growth of other trees exists not affected. This is done according to criteria concerning minimum tree size for harvesting, specifications of the numeral, spacing and size categories of residual trees per area, and allowable cut.
Selection cutting, also known as the selection system, stands the silvicultural practice of harvesting trees in a manner that drives a forest stand towards uneven-aged or all-aged circumstances, or 'structure'.

Your Mother needs to transfer (i.e., encode) a list of 25 vocabulary words from her STM to her LTM. She asks for your help. You suggest that she use elaborative rehearsal and you begin to train her in this technique. What do you ask your Mother to do?
1) you ask her to repeat the words over and over again
2) you ask her to give each word meaning by using each word in a sentence
3) you ask her to break down each word into various "chunks"
4) you ask her to memorize each word and its meaning
*PLEASE ADD EXPLANATION*
The best technique for your mother is that she uses each word in a sentence to give it a meaning, and remember it better (option 2).
Elaborative rehearsal is a common technique used to remember information in a long-term way. Due to this, this technique can be used to move information from short-term memory to long-term memory.
In this technique, the main purpose is to associate the new information with something you already know. In learning new words, this can include:
Associating new words to images.Creating examples of sentences.Associating a new word to a synonym you already know.In this context, the technique that is part of elaborative rehearsal is using the word in a sentence (option 2).

explain why antibiotics are not consistently effective against infection of bacteria
Explanation:
Antibiotic resistance happens when germs like bacteria and fungi develop the ability to defeat the drugs designed to kill them. That means the germs are not killed and continue to grow. Infections caused by antibiotic-resistant germs are difficult, and sometimes impossible, to treat.
