In a population of 100 people, 30 have brown hair and 70 have black hair. What is the Relative Frequency for Black hair?

Answers

Answer:

0.7

Explanation:

Given that in statistics, the Relative Frequency is the Frequency of the class divided by Total.

Hence, in this case, the Relative Frequency of black hair is the Frequency of black hair divided by the Total.

Hence, we have 70 ÷ 100

=> 0.7

Therefore, the correct answer is 0.7 Relative frequency.

Los insectos polinizadores son especies clave en muchas comunidades que interacción interespecífica se da entre estos insectos??

Answers

Answer:

Competencia interespecífica

Explanation:

Los polinizadores son organismos esenciales para el equilibrio de las comunidades silvestres y el mantenimiento de la biodiversidad existente en el planeta. Los insectos (especialmente las abejas) representan el grupo de polinizadores más importantes, estos organismos consumen el néctar como alimento y simultáneamente son utilizados por plantas para reproducirse mediante el trasporte del polen de una flor a otra. Los insectos polinizadores usualmente visitan muchos diferentes tipos de plantas y, a su vez, estas plantas son polinizadas por diferentes grupos de insectos polinizadores. Como consecuencia de esto último, entre polinizadores se establece una competencia interespecífica por un recurso (es decir, el polen) el cual a priori podría considerarse limitado. Sin embargo, ha sido demostrado que las redes e interacciones entre plantas y polinizadores están organizadas de tal modo que la competencia interespecífica entre polinizadores se encuentra reducida drásticamente, siendo incluso beneficiosas para las especies que la componen. Estos resultados se encuentran soportados por el análisis de información a campo la cual demuestra como redes entre polinizadores y plantas son similares en diferentes ecosistemas/continentes y también porque cuando tales conexiones gozan de buena salud se observa un aumento de la biodiversidad en las comunidades ecológicas.

In mice, agouti coloration (A) is a dominant trait for fur color over black fur
(aA Punnett square diagram is provided. A particular generation of
offspring has a ratio of three agouti individuals to one black individual.
Which of the following genotype combinations is possible for the parent



A: aa x aa

B: AA x Ar

C:Aa x Aa

D: AA x AA

Answers

Answer:

C. Aa x Aa

Explanation:

According to this question, one gene coding for fur coloration in mice is involved. The allele for agouti coloration (A) is a dominant trait over black fur (a). This means that a heterozygote mouse will have an agouti coloration.

Based on this question, two parents were crossed to produce offsprings that have a ratio of three agouti individuals (3) to one black individual (1). Based on this phenotypic ratio, only parents that are both heterozygous for the fur color gene can produce it. That is, a cross between Aa and Aa mice parent. Hence, the genotype combination of Aa × Aa is possible for the parent to produce offsprings with 3 Agouti : 1 black.

Answer: C) Aa x Aa
