whats the difference between ex vivo and in vivo gene therapy
Answer:
Ex vivo gene therapy - this is carried out by removing the intended cell from the patient's body before administration of the gene therapy, after which the cell is returned.
In vivo gene therapy - this is carried out directly on the cell while its still on the patient's body.
Explanation:
Ex vivo, Latin for "out of the living" is a process that takes place outside an organism. Scientifically, ex vivo involves experiments that are conducted outside of a living body; the tissues or organs are taken out of the body, experimented on and returned.
In vivo which is Latin for "within the living" on the other hand is a process that take place outside an organism. Unlike ex vivo, it involves experiments that are conducted with or within a living body.
Gene therapy refers to a process that is carried out to alter the genetic make up of an individual with the intent of treating a disease.
In ex vivo gene therapy, the intended cells are removed from the patient's body and the gene therapy is applied to the cells before they are put back in the patient's body. But with in vivo gene therapy, the gene therapy is applied directly on the intended cells while its on the patient's body.

What is the difference between food chains and food webs? Food webs show the flow of energy from producers to consumers, and food chains show the flow of energy from consumers to producers. Food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem. About ten percent of the energy is passed on to the next trophic level in food webs, but in food chains, about ninety percent is passed on to the next trophic level. Heat is lost when energy is passed on to the next trophic level in food chains, but in food webs, heat is not lost when energy is passed on to the next trophic level.
Answer:
Food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem.
Explanation:
Unlike food chains, food webs show more detailed information about the different animals in an ecosystem and show multiple energy transfers to different animals from the same sources.
By looking at these examples, you will notice a dramatic difference in detail:
Food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem.
What is food chain?Food chain shows the relationship between organisms by the food they eat.
What is food web?A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
Difference between food chain and food webFood webs show interconnection of food chains about the different animals in an ecosystem and different energy transfer processes.
Thus, food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem.

what type of pathogen causes malaria?
Answer:
Malaria is caused by the Plasmodium parasite. The parasite can be spread to humans through the bites of infected mosquitoes. Plasmodium falciparum is mainly found in Africa.
Hope this helped :)
Answer:
protists
Explanation:
Organisms that cause disease to humans are known as "pathogens." There are many different types of pathogens such as: bacteria, fungi, virus, parasitic worms and protists.
Malaria is caused by the following parasites: Plasmodium ovale, Plasmodium malariae, Plasmodium falcifarum and Plasmodium vivax. These parasites are also known as "protists pathogens." They are transmitted by the female Anopheles mosquito and are being transferred to humans through mosquito bites. The parasites then thrives in the red blood cells of the infected individual.
Which of the following domains include prokaryotic organisms?
A. Archaea only
B. Eukarya only
C. Archaea and Bacteria
D. Bacteria only
C. Archaea and Bacteria
Archaea and Bacteria are categorized into the domains of prokaryotic organisms, hence option C is correct.
What are prokaryotic organisms?There are three domains of the life the Archaea, the Bacteria, and the Eukarya, in which Archaea and Bacteria belong to prokaryotic cells but eukaryotic cells belong to the Eukarya domain.
Prokaryotic organisms include the organism's absence of a nuclear membrane and not having well-defined cell organelle, this includes bacteria. It is a unicellular organism having an asexual mode of reproduction.
The Eukarya domain includes the eucaryotic cells having a true nuclear membrane, this domain includes all the eukaryote plants the human beings.
Therefore, Archaea and Bacteria is the correct option.

In homologous recombination in E. coli, the protein that moves along a double-stranded DNA, unwinding the strands ahead of it and degrading them, is:
Answer:
RecBCD enzyme
Explanation:
RecBCD is an enzyme of the E. coli bacterium that initiates recombinational repair from potentially lethal double strand breaks in DNA which may result from ionizing radiation, replication errors, endonuclease, oxidative damage, and a host of other factors. The RecBCD enzyme is both a helicase that unwinds, or separates the strands of DNA, and a nuclease that makes single-stranded nicks in DNA.
Which statement correctly describes the number of chromosomes in body cells and gametes?
Answer:
its A
Explanation:
Body cells and gametes are both diploid correctly describes the number of chromosomes in body cells and gametes.
What are chromosomes?A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones.
Chromosomes are threadlike structures made of protein and a single molecule of DNA that serve to carry the genomic information from cell to cell. In plants and animals (including humans), chromosomes reside in the nucleus of cells.
One molecule of DNA and one protein make up one chromosome. Chromosomes are different sizes, and proteins called histones allow them to pack up small enough to fit in a nucleus.

The plants in the
were allowed to self-pollinate.
The plants in the
are true breeding.
After a cross, there are three times as many tall plants as there are short plants in the
.
Answer:
The plants that were allowed to self pollinate were the First filial generation, filial, Latin for family. Or just the F1 generation plants.
The plants that are true breeding are Parental generation or for shorthand, the P generation plants.
The plants where there were three times as many tall plants as short plants are in the second filial generation, or the F2 generation.
This question is based on the Mendel’s Experiment.
Sir Gregor Johann Mendel.
Mendel experimented on pea plants and gave the laws for genetics which are a very important aspect of hereditary. Because of his experiment the terms recessive and dominant came into light and how the genes are passed from generations were also studied.
The statements can be completed as:
Plants that were allowed to self pollinate were F1 or the first filial generation.The true-breeding plants are P (parental) generation.The plants having the phenotypic ratio of 3:1 for tallness and shortness are in F2(second filial) generation.The steps can be explained as:
The cross which is the first step between the given alleles of a trait in a cross is called parental (P) generation.The progenies produced as a result of a cross between the parental traits is called the first filial (F1) generation.When the traits from the F1 is interbred then a second filial generation (F2) is produced.To learn more about parental and filial generations follow the link:
