Answer:
Dideoxynucleotides are chain-elongating inhibitors of DNA polymerase, used in the Sanger method for DNA sequencing. They are also known as 2',3' because both the 2' and 3' positions on the ribose lack hydroxyl groups, and are abbreviated as ddNTPs.

Explanation:
A vaccine is a substance that contains all or part of a noninfectious version of a disease-causing organism. When the vaccine is administered to a person, the person's immune system attacks the noninfectious version of the organism and learns to recognize its surface proteins. The next time the immune system comes in contact with the same surface proteins, it has a defense already prepared in order to respond quickly to the invading organism. In this way, a vaccine gives people immunity to the disease-causing organism.Vaccines can be life-saving, but there have been a few cases of people catching a disease from the administered vaccine.How might genetically engineered organisms solve this problem?
Answer:
GMOs can be used to produce cheaper, easier to administer, and safer vaccines
Explanation:
Genetically modified organisms (GMOs) are organisms whose genomes have been altered in the laboratory by using genome engineering techniques. These GMOs have a fundamental role in clinical research and they have been increasingly used in the last decades for developing safer and cheaper vaccines. For example, genetically engineered hepatitis B vaccines have been developed with recombinant DNA techniques using genetically modified yeast (Saccharomyces cerevisiae). Moreover, GMO plants are nowadays also being used to develop consumable vaccines which can be orally administered to be absorbed and assimilated through digestion.
How would the overfishing solution be implemented?
Answer:
Implementing the limit of the fish catch number is one of the best ways to reduce overfishing. By limiting the fish catch, the government and other organizations could help the fish population to recover and breed another fish. So the fish population will not extinct.

Answer: Ok so i answer every one that has a question mark?
Explanation:
When birds migrate into or out of a defined population and mate with birds from another population, the existing pool of genes may be altered. Migration can increase or decrease gene frequencies in populations, resulting in...
greater genetic variation, which may enhance chances of survival.
less genetic variation, which will not influence chances of survival at all.
selective breeding, which may enhance chances of survival.
natural selection, which will not influence chances of survival at all.
Answer:
i belive it is A
Explanation:
i am not at all positive so dont come at me but hopefully this helps
Migration can increase or decrease gene frequencies in populations, resulting in greater genetic variation, which may enhance chances of survival.
What do you mean by genetic variations?Genetic variation is the difference in DNA among individuals or the differences between populations. The multiple sources of genetic variation include mutation and genetic recombination.
Genetic variations can arise from gene variants (also called mutations) or from a normal process in which genetic material is rearranged as a cell is getting ready to divide (known as genetic recombination).
The genetic diversity has three different sources: mutation, recombination and immigration of genes. Mutation is the driving force of genetic variation and evolution.

Which type of fertilization occurs in humans? Explain your answer.
Internal fertilization
Explanation:
everything takes place inside a female womb
Answer:
When the sperm and egg(ovum) fuse, their fusion is called fertilization.
Explanation:
Since it takes place inside the body of the female.it is an internal fertilization. During this process, the nuclei of sperm and egg fuse to form a single nucleus. The resultant single cell,formed after the fertilization, is called zygote.

Which of these events does not occur during telophase?
Answer:
A, the chromosomes dont ¨relax¨.
Explanation:
Chromosomes during telophase are doing all exept A
The event that does not occur during telophase is cytoplasm splitting into two, which is in the second option, because this phenomenon occurs after telophase, which is in the cytokinesis of the cell cycle.
What is the function of telophase?Telophase is the final stage of mitosis/meiosis and follows the stages of prophase, prometaphase, metaphase, and anaphase, during telophase, the chromosomes start to decondense and become less visible under the microscope, as they are no longer tightly packed together, and a new nuclear envelope begins to form around each set of chromosomes, creating two separate nuclei. There is no cytoplasmic division in the telophase.
Hence, the event that does not occur during telophase is cytoplasm splitting into two, which is in the second option.

Match the descriptions to the correct type of fungi. has positive and negative mating strands has erect fruiting body the first fungi to evolve lives in a varied habitat and exhibits all forms of nutrition chytrid arrowRight common mold arrowRight sac fungi arrowRight club fungi arrowRight
Answer:
Fungi are unicellular or multicellular eukaryotic organisms that are dependent for their energy and food on dead organic material or other organisms. These organisms produce by both sexual and asexual reproduction.
1. club fungi show a bipolar mating system as they have positive and negative mating strands.
2. sac fungi have an erect fruiting body filled with asci.
3. The chytrids have a cell wall of chitin, a flagellum, absorptive structures for nutrition therefore have a lineage.
4. The common molds grow in the form of hyphae and shows all for of nutrition and live in every possible habitate.

How specialized structures increase the probability of successful reproduction in the plants, and factors that affect their growth?
Answer:
Specialized structures such as
1. The brightly colored flowers attract insects that transfer pollen from the anther to the stigma of another plant.
2. The scented smell of flowers and their nectars also attract insect and other pollinators to them.
Explanation:
Reproduction refers to the way by which plants and animals produce offspring or their types. Pollination, which is the transfer of pollen grains from the anther to the stigma of the same or another flower is a vital way by which plants accomplish this.
Structures of plants such as their brightly colored flowers, the nectars produced by them, as well as their characteristic smells attract pollinators to them that, in turn, aid reproduction.
