1) Cells duplicate their chromosomes before dividing instead of after because the daughter cells would each lose one-half of the genetic information.

The duplication of chromosomes automatically leads to the duplication of the genetic information on the chromosomes and each daughter cell receives a copy each of the genetic information.

If the information are not duplicated before dividing, it means that each daughter cell will receive half information.

2) If a cell that starts with 16 chromosomes lost half of its genes during each cell division, it will take 4 divisions for the gene to remain 1.

  • First division, the genes would remain 8 from 16
  • Second division, the genes would remain 4
  • Third division, the genes would remain 2
  • Fourth division, the gene would remain only 1.

After researching the possible effects of music, Elaina proposes that if people listen to faster-paced music, their pulse rates
Angelina_Jolie [31]

Answer:

Constant variables

Explanation:

Elaina's investigation lacked the critical ingredient of constant variables which are important components of every scientific investigation. In every research, there are 3 important variables, namely:

1. Dependent variables: the actual variable to be measured during the course of investigations and whose values are dependent on another variable (independent variable) supplied by the investigators.

2. Independent variable: one of the variables that are supplied by investigators whose values are often manipulated to see the kind of changes it will cause to the dependent variable.

3. Constant variables: other variables that are neither independent nor dependent but constant for all the various experimental groups in investigations.
