Answer:
1) I begin as a carbon molecule present in the atmosphere
2) I am absorbed by trees during photosynthesis
3) carbon is incorporated into decomposed organisms
4) next, it enters deceased organisms and waste buried in the ground
5) millions of years later, it becomes fossilized
6) fossil fuels utilized by factories then release carbon dioxide back into the atmosphere (returning to starting point
if you want the entire cycle then..
7) utilized again by a tree
8) released as organic carbon (some)
9) a tree leaf is consumed by an animal, which then expels carbon either by respiration or after it dies
To fix a thymine dimer via nucleotide excision repair, the sequence of enzyme activity is Endonuclease, DNA polymerase I, and DNA ligase. Two primary methods exist for repairing thymine dimers; one is photoreactivation, where an enzyme activated by blue light repairs the dimer, thus restoring the proper base pairing. The alternative method is excision repair, involving the uvr system that removes the dimer, with the gap filled by DNA polymerase I's proofreading capability.
Answer:
36
Explanation:
A two-point test cross involves mating an individual with a double heterozygote genotype against a homozygous recessive one to ascertain the recombination frequency between two linked genes. In genetic terms, one map unit (m.u.) is indicative of the genetic distance separating genes for which one (1) of a hundred (100) meiotic products is recombinant. Here, 36 of the progeny exhibited the recombinant phenotype, while the other 64 did not, indicating that the two genes are spaced by 36 mu (64 + 36 = 100 >> 36 mu).
Answer:
1. Mutation- enhances genetic variation
2. Selection- may raise, lower, or maintain genetic variation
3. Genetic drift- diminishes genetic variation.
4. Gene flow- could either enhance or reduce genetic variation
Explanation:
1. Mutation denotes changes in an organism's DNA. The mutations lead to new adaptive traits that evolve, which increases the genetic diversity of organisms.
2. Natural selection favors organisms best suited to their environment. Thus, selection can increase, decrease, or keep variation in a population steady.
3. Genetic drift occurs due to random events altering a population's gene pool. When this phenomenon transpires, the genetic variation within that population typically decreases.
4. Gene flow involves changes to the gene pool due to immigration and emigration. This factor can thus increase or decrease genetic variation.
Respuesta:
La opción B es correcta porque en todas las actividades, dirigir, ordenar y controlar no son aspectos de la coordinación de incidentes.
Explicación:
Para comprender esta pregunta, es necesario saber quién es el coordinador de incidentes. Él es la persona encargada de las tareas relacionadas con el proceso administrativo y asegura que las actividades en el lugar se estén realizando correctamente. A continuación, se detallan las funciones que son responsabilidad exclusiva del coordinador de incidentes:
• Establecer la interacción entre diferentes agencias y partes interesadas.
• Recopilar y analizar la información enviada.
• Establecer las prioridades del incidente.
• Rastrear los recursos.
• Sincronizar mensajes de servicio público.
Estas son las principales funciones o actividades que realiza el coordinador de incidentes. Él gestiona y no tiene autoridad para controlar o dirigir a personas en el departamento u oficina. De igual manera, no tiene la responsabilidad de dar órdenes al personal.
Detalles de la respuesta:
Nivel: Secundaria
Asignatura: Biología
Palabras clave:
• Coordinador de incidentes
• Parte interesada
