Answer:

Statement 4

Explanation:

1 and 2 are obviously wrong because DNA holds genetic information and doesn't do cell respiration and chlorophyll is a protein not DNA.

3 is wrong because interphase is the first part of mitosis and the chromosomes haven't formed or separated yet.

4 is correct because chromosomes have DNA (and some proteins)

Jason has five equally massed lead fishing weights, each weighing 250 grams. What is the total mass of the five lead fishing wei
algol [13]

Answer:

1250 g=1.25 Kg

Explanation:

We are given that Jason has five fishes of equally massed lead fish weights.

Weigh of each fish =250 grams

We have to find the value of total mass of the five lead fishing weights

Total number of fishes=5

In order to find the total mass we will use unitary method

Total mass is obtained by multiplying the total number of fishes with weight of one fish

Total mass=5\times 250

Total mass of five fishes=1250 g

1 kg =1000g

Then 1250 g=\frac{1250}{1000}=1.25 Kg

Hence, total mass of five lead fishing weights=1250 g=1.25 Kg
