Answer:
Explanation:
Beneficios: desarrollar inmunidad,ayuda al sistema inmunológico a desarrollar la misma respuesta que una infección real, para que pueda desarrollar anticuerpos y combatirla en el futuro.La viruela se ha erradicado por completo gracias a las vacunas y la poliomielitis no se queda atrás. Las vacunas contra la polio todavía se administran para ayudar a mantener el control de la enfermedad hasta que se haya eliminado en todo el mundo.
Daño: síntomas de un resfriado o fiebre leve que muestra que su cuerpo está combatiendo la infección. Puede haber dolor en los músculos o enrojecimiento en el lugar de la inyección. Todos estos efectos secundarios muy leves desaparecen en un par de días, las alergias
NO TOME LA VACUNA
The correct answer is rapids and waterfalls.
Rapids refers to the segments of streams with extensively vigorous currents, various obstacles, and steps in their streambeds. A waterfall refers to a vertical drop in a stream bed. Both are the locations of vigorous erosion.
The rapids are generally produced where the resilient bedrock limits a stream to a narrow channel and forces an enhancement in the velocity of water.
On the other hand, waterfalls are produced where the fast-flowing water negotiates a geologic contact amid the more resilient and less resistant layers of rock, or through a fault, which has analogized distinct kinds of rocks. Or it can be said that waterfalls usually produce at the end of a series of rapids.
1.photosynthesis is anabolic while cellular respiration is catabolic
2.photosynthesis occur in the day while cellular respiration take place any time
Answer:
The correct answer is - 0.084
Explanation:
Sickle cell anemia is a autsmal recessive blood disorder of RBCs where RBC shape altered to the sickle shape or cresecent moon that obstruct and damage the veins and artries.
Normal allele is represented by - HbA - p
sickel cell allele is represented by - HbS - q
genotype frequency of normal allele HbA in the population = p2
genptype frequency of HbAHbS in the population = 2pq
genotype frequency of autosomal recessive HbS = q2 = 0.007 (given)
So, the allelic frequency of the recessive allele =
q = √ 0.007 = 0.08366 or 0.084
