D to trace the inheritance of human traits in humans

Answer: The correct answer is- (D) To trace the inheritance of traits in humans.

Pedigree is a representation of family members ( in the form of flow chart with specific symbols) that indicates a trait ( such as sickle cell anemia, which is an autonomous recessive trait) in a family and across many generations.

Pedigree analysis is done to determine genotypes, morphological form, and predict the chances of passing a trait in the next generation.

There can be different inheritance pattern for a trait ( such as dominant, recessive, autosomal, or sex-linked).

Thus, genetic counselors perform pedigree analysis in order to help families in identifying the risk of genetic disorders and are used by research scientists in determining inheritance pattern of traits in humans.

The average rate of consumption of br− is 1.86×10−4 m/s over the first two minutes. what is the average rate of formation of br2

Scorpion4ik [409]

By considering the reaction equation is:
5Br(aq)+BrO3(aq)+6H(aq)= 3Br2(aq)+3H2O(l)
when the average rate of consumption of Br = 1.86x10^-4 m/s
So from the reaction equation
5Br → 3Br2 when we measure the average rate of formation (X) during the same interval So,
∴ 1.86x10^-4/5 = X / 3
∴X = 1.1 x 10^-4 m/s
∴the average rate of formation of Br2 = 1.1x10^-4 m/s

which two quantities are used to predict gravitational force according to Newton's law of universal gravitation a. mass and spee

NISA [10]

Answer:

(b). Mass and distance.

Explanation:

The gravitational force between two objects is given by Newton's law of universal gravitation. The formula is as follows :

$F=G\dfrac{m_1m_2}{r^2}$

Here,

G is universal gravitational constant

r is the distance between two objects

It is very clear that the gravitational force is directly proportional to the product of masses and inversely proportional to the square of the distance between them.

Hence, the two quantities are used to predict gravitational force according to Newton's law of universal gravitation are mass and distance.
