Usually, only mammals undergo Carnegie stages.
Therefore, 'B. Sheep' would be the correct answer.
Answer:
<u>independent variable:</u> size of soccer ball
<u>dependent variable</u>: period of time the balls stay in the air
<u>control variable</u>: parts of the body used to juggle the ball
Explanation:
The independent variable is the manipulatable variable supplied into an experiment. It is a variable that directly affects the dependent variable.
The independent variable is the outcome variable. It is the variable that is primarily measured from experiments whose value depends on the value of the independent variable.
The control variables are those that are kept constant throughout the course of experiments. In other words, they do not directly affect experimental outcomes.
Hence, in the illustration;
<u>independent variable</u>: size of soccer ball
<u>dependent variable</u>: period of time the balls stay in the air
<u>control variable</u>: parts of the body used to juggle the ball
Nucleus controls the cell, it tells the cell what to do, similar to a brain. Rough ER or Ribosome ER creates the proteins in the cell. Golgi Apparatus packages macromolecules like lipids and proteins for transport.
Answer: The answer is that the phenotypic ratio among phenotypes produced from an F1 X F1 dihybrid cross is 9:3:3:1.
Explanation:
Independent assortment of genes explains how alleles on different chromosomes arrange independently of one another during gamete formation.
So, a dihybrid cross involving TWO characters (e.g Seed color & seed shape) would have its respective alleles DISTRIBUTED whether dominant or recessive, for crossing to occur and yield varying proportion of offspring in the well spread ratio of 9:3:3:1; making it a consequence of independent assortment of genes
