Answer

Step 1

Toy 1 = 0.953

Toy 2 = 2.177

Step 2

Toy 1 = 953g

Toy 2 = 2177g

Explanation

Since we know that 1kg = 2.2026, if we divide 1kg by 2.2026, we get how much 1 pound is equal to. We then times that by the weight of the toy, and we get the weight in kg.

Toy 1

2.2046 lbs = 1 kg

2.1 lbs = ?

2.1 lbs =  \frac{1}{2.2046} X 2.1

= 0.9525

To the nearest thousandth = 0.953

Toy 2

2.2046 lbs = 1 kg

4.7 lbs = ?

4.7 lbs = \frac{1}{2.2046} X 4.8

= 2.177

To the nearest thousandth = 2.177

Step 2

To convert kilograms to grams, we times the kg total by 1000, to get the mass in grams. (1kg = 1000g).

Toy 1

0.953 x 1000 = 953g

Toy 2

2.177 x 1000 = 2177g

A scientist has a pea plant with yellow seeds. It has one allele for yellow seeds (Y) and one for green seeds (y).
Eva8 [605]

Answer:heterozygous

Explanation:

The genotype of an organism is its genetic makeup which is characterized by the presence of alleles of a gene.

The genotype can be broadly of two types :

1. Heterozygous - when an individual has 2 different variants of a gene known as alleles, then the person is said to be heterozygous for that gene.

2. Homozygous - if both the alleles of a gene are the same, then the person is said to be homozygous.

Since in the given situation you have two different alleles - yellow and green represented by Y and y, the individual is heterozygous.
