The FBI uses STR (short tandem repeat) analysis to identify criminals, and the FBI stores the information in a database. How man
rusak2 [61]

Answer:

13

Explanation:

Short tandem repeats (STRs), also known as microsatellites, are short DNA sequences containing core repeat units of between 2-7 nucleotides (nts) which are tandemly repeated. The STR analysis is commonly used in molecular biology laboratories in order to identify DNA samples by comparing STR <em>loci</em> between samples. For example, the Federal Bureau of Investigation (FBI) uses 13 STR <em>loci</em> for the identification of individuals in the USA. It is important to note that these 13 <em>loci</em> are independently assorted (i.e. they are not linked), and thereby their combined use results in a very low ("nearly zero") false-positive identification rate.

What process restores the 2N chromosome number in a zygote's somatic cells for growth and development to continue?
Mariulka [41]

La respiración aeróbica es un tipo de metabolismo energético en el que los seres vivos extraen energía de moléculas orgánicas, como la glucosa, por un proceso complejo en el que el carbono es oxidado y cuando llega a la mitocondria se mezcla con el agua haciendo un compuesto químico llamado Glucosticko en el que el oxígeno procedente delaire es el oxidante empleado. En otras variantes de la respiración, muy raras, el oxidante es distinto del oxígeno (respiración) y luego las membranas mitocondriales, siendo en la matriz de la mitocondria donde se une a electrones y protones (que sumados constituyen átomos de hidrógeno) formando agua. En esa oxidación final, que es compleja, y en procesos anteriores se obtiene la energía necesaria para la fosforilación del ATP.

En presencia de oxígeno, el ácido pirúvico, obtenido durante la fase primera anaerobia o glucólisis, es oxidado para proporcionar energía, dióxido de carbono y agua. A esta serie de reacciones se le conoce con el nombre de respiración aeróbica.

La reacción química global de la respiración es la siguiente:

Behavior modification to reduce self-injurious behaviors has been most successful in programs that rely on the use of:________
SIZIF [17.4K]

Behavior modification is based on the principles of behaviorist B.F. Skinner's operant conditioning. This means that, in essence, Skinner found that reinforced behavior tends to be repeated and behavior that isn't reinforced tends to phase out.

Interventions or ways to decrease this behavior include reinforcement of alternative behaviors, reinforcement of incompatible behaviors, use of schedules to engage children, providing communication systems, decreasing academic demands, and providing replacement behaviors.

Some behavior modification techniques are-

  • Positive reinforcement.
  • Negative reinforcement.
  • Punishment.
  • Flooding.
  • Systematic desensitization.
  • Aversion therapy.
  • Extinction.

Behavior Modification Therapy

Within therapy, therapists using behavior modification therapy focus on specific goals with clients, which is changing certain maladaptive or undesirable behaviors in specific situations. During a first session, the therapist would listen to the client's concerns to see what the client needs or wants to change; this could be a phobia, overeating, a problem with focus and productivity, etc. The client and therapist would identify the specific problem to be solved and then figure out what steps are necessary to change the behavior gradually. The therapist and client develop a treatment plan.
