<span>Great minds combined with technological advancements have a lead to creations and achievements that would have been impossible. Whatever great scientist of the past has achieved have already been surpassed or improved through modern and innovative ideas and processes. An excellent example of which is the direct manipulation of an organism’s DNA, also known as genetic engineering or genetic modification (GM). Coming from the terms genes and modify, the entire process is something out of a science fiction movie. Well, it used to be that way until the practice was perfected and used in actual applications. Genetic engineering made it possible to add new DNA or alter bad ones.</span>

Explanation:
1: Seeds provide a protective coat so that the plant can develop when it finds nice soil.
2: Seeds have pre-packaged foods sources.
3: Seeds are very easily dispersed by animals, wind, water, ect...
4: Seeds have the capability to survive without water.
Drug that demages capsule is used to treat viral infection because Curing a viral infection antibiotics are useless against viral infections. This is because viruses are so simple that they use their host cells to perform their activities for them. So antiviral drugs work differently to antibiotics, by interfering with the viral enzymes instead.
Antiviral drugs are currently only effective against a few viral diseases, such as influenza, herpes, hepatitis B and C and HIV – but research is ongoing. A naturally occurring protein, called interferon (which the body produces to help fight viral infections), can now be produced in the laboratory and is used to treat hepatitis C infections.
Answer:
El híbrido va a ser esteril.
Explanation:
En la cruza entre dos especies distintas, cuando ocurre, existen distintos mecanismos de aislamiento reproductivo, que son barreras que inhiben o interrumpen el flujo génico entre especies distintas. Es decir que no habrá exito reproductivo de estas cruzas. Se trata de caracteres biológicos propios de cada especie que previenen la reproducción con otras especies.
Estos mecanismos de aislamiento reproductivo pueden ser precigóticos o postcigóticos.
1.Pre-copulatorios o pre-cigóticos:
- Ecológico o por aislamiento de hábitat;
- Por incompatibilidad de gametas.
2. Post-copulatorios o cigóticos:
- Inviabilidad del híbrido;
- Híbrido con viabilidad o fertilidad disminuido;
- Interacciones citoplasmáticas.
La mula es producto de la cruza entre dos especies distintas: una yegua (Equus ferus caballus) y un burro (Equus africanus asinus). Es un ejemplo de la accion de mecanismo poscigótico, en el cual se forma un híbrido viable esteril. Este ejemplar puede nacer, crecer y sobrevivir, pero que no puede producir gametas funcionales, por lo cual no puede reproducirse.
Answer:
c. none of the subjects to show signs and symptoms of a cholesterol deficiency during the entire study.
Explanation:
this is because the blood cholesterol is from two sources. Nearly 80% of the cholesterol the body needs are made by the liver and intestine.certain small amounts are also produced in the adrenal glands and the reproductive organs.The remaining fragment amounts comes from the diets.
Therefore even if these subjects were fed with diet without cholesterol, it will not have any significant effects on the body cholesterol composition. Therefore no symptoms of its deficiency will be observed.
Generally it biosynthesis is regulated by the amount of cholesterol present in the blood.
