Plz help due now As children age, how do their psychological and physical abilities change?
ArbitrLikvidat [17]

Answer:

The various stages of development in children are reached at a unique time and rate for every child. But there are a number of common key categories to consider when looking at your child’s early health and development. Explanation:

In infancy, toddlerhood, and early childhood, the body’s physical development is rapid (Figure 1). On average, newborns weigh between 5 and 10 pounds, and a newborn’s weight typically doubles in six months and triples in one year. By 2 years old the weight will have quadrupled, so we can expect that a 2 year old should weigh between 20 and 40 pounds.

HOPE THIS HELPS :)

With independent assortment, the ratio of genotypes in the F2 generation of a cross between true-breeding strains (AA bb x aa BB
MariettaO [177]

Answer:

c. Aa Bb

Explanation:

The parents were pure breeding with genotypes AAbb and aaBB. A cross between AAbb and aaBB would produce AaBb genotypes in F1 progeny. Two F1 strains would be crossed to produce F2 progeny. The F2 progeny would have the genotype ratio= 1:2:1:2:4:2:1:2:1.

Out of all the obtained genotypes in the F2 generation, the proportion of "AaBb" genotype was 4/16. Therefore, "4" in the given ratio represents the genotype "AaBb".
