Answer:
Bacteria is a type of micro-organism and is also a prokaryote. These organisms can only be seen using a microscope. Some bacterias are harmful while some are helpful for human daily lives, such as probiotics, and are necessary for life. They have simple cell structures as there is no nucleus or membrane-bound organelles. Bacterias can be found in soil, water, plants, animals, etc. They can cause diseases such as Tuberculosis etc. Due to some diseases being caused by bacterias, doctors prescribe Antibiotics which has the ability to stop the activities in bacterial cell that causes it to lose its protective outer covering and completely stops it from multiplying.
Answer:
Bacteria are among the smallest living things. A single bacterium consists of just one cell, and is called a single-celled, or unicellular organism.
Even though it is just a single cell, it can carry out all seven life processes (movement, respiration, sensitivity, growth, reproduction, excretion and nutrition).

Genetic engineering involves various stages.
1 human DNA is inserted into bacterial plasmid DNA
2 recombinant plasmid inserted into bacteria
3 restriction enzyme cuts bacterial plasmid DNA
4 restriction enzyme cuts human DNA
What is the correct sequence for genetic engineering?
Answer:
4, 3, 1, 2
Explanation:
FIRST: cDNA is synthesized to be used as a gene of interest: processed (spliced) mRNA (no introns) is reverse transcribed to cDNA using reverse transcriptase, an enzyme from retroviruses
SECOND: Restriction enzyme used to cut GOI
THIRD: Same Restriction enzyme used to cut plasmid (sticky ends are created)
FOURTH: GOI connects/hybridizes with plasmid due to base-pairing
FIFTH: DNA ligase connects the recombinant DNA strands

Why are viruses not living??
Answer:
Viruses are not living cause they need any host (body or living organism) To perform its function.
Explanation:
Answer:
Viruses are not living things. Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own way they can do nothing until they entered a living cell. Without cells viruses will not be able to multiply. Therefore viruses ante not living things.

Answer:
Plasmolysis is defined as the process of contraction or shrinkage of the protoplasm of a plant cell and is caused due to the loss of water in the cell. Plasmolysis is an example of the results of osmosis and rarely occurs in nature.
The word Plasmolysis was generally derived from a Latin and Greek word plasma – The mould and lusis meaning loosening.

Explanation:
I got it right lol and have a good day <3
Option B A suspect’s mtDNA sample is matched to an unknown sample of mtDNA that was found at a crime scene is correct.
What is Mitochondrial DNA (mtDNA) typing?Mitochondrial DNA (mtDNA) typing is used in forensic science to analyze DNA evidence in cases where the DNA material is degraded or present in small amounts, such as in hair shafts, bones, and teeth.
mtDNA typing is also useful in cases where a person's nuclear DNA (which is unique to each individual) is not available or is contaminated with DNA from multiple sources.
mtDNA is inherited maternally and is present in multiple copies in each cell, making it more abundant and resistant to degradation than nuclear DNA.
Forensic scientists can compare the mtDNA profile of a suspect with mtDNA evidence found at a crime scene to determine whether the suspect's DNA could have contributed to the evidence.
Since mtDNA is not unique to each individual and is shared among maternal relatives, mtDNA evidence alone cannot definitively identify a suspect, but it can help exclude individuals who do not share a common mtDNA profile with the evidence.
Hence option B is correct.
