Answer:

Independent variable: Glass of milk

Dependent variable: Time of sleep

Control variable: same type of milk

Explanation:

Independent variable in an experiment refers to the variable that the experimenter manipulates or changes in order to get a response in another variable (dependent). In this case, the independent variable is the GLASS OF MILK taken before bed.

Dependent variable is that variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the dependent variable is the TIME OF SLEEP of the students.

A control variable or constant is the variable that is kept unchanged throughout the course of the experiment in order not to alter the outcome of the experiment. In this experiment, a control variable can be the SAME TYPE OF MILK taken by each student.

SCORPION-xisa [38]

Answer:

Genotype of parents:                  Ss     x     ss

Genotype of offsprings:                  Ss    ss

Expected ratio of short to long:      2  :   2 = 1 :  1

The actual ratio in this problem is Eight kittens have short hair and 3 have long hair: 8 : 3

Explanation:

In cats the allele for short hair is dominant over the allele for long hair. (SS or Ss for short hair; ss for long hair).

A short haired male and long haired female have kittens. Eight kittens have short hair and 3 have long hair.

For the parents to have been able to produce long haired offsprings, it means both parents possess one copy each of the recessive traits. Thus we have

Phenotype of parent: A short haired male and long haired female

Genotype of parents:                  Ss     x     ss

Genotype of offsprings:                  Ss    ss

Expected ratio of short to long:      2  :   2 = 1 :  1

The actual ratio in this problem is Eight kittens have short hair and 3 have long hair: 8 : 3

Do you think you would have some genetic traits similar to your grandparents? EXPLAIN your answer.
pogonyaev

Answer:

Yes.

Explanation:

Genes are passed on from generation to generation. When a male and a female produce an offspring, the offspring would get half of their genes from their mother, and the other half from their father.So your parents get half of their genes from their parents, (which in this case, are your grandparents) and they pass them on to you. Unlike your parents, you get traits from both sides of your family, some from your mother's side and some from your father's side.

This is why you share similar traits as your grandparents and at the same time,there is also a chance that you also share some (of course not all) traits with your direct cousins, because they also share some traits to your grandparents.

How long ago did speciation occur between tarsier and the ancestor of all the anthropoids?
inysia [295]
A tarsier, although a primate, is not an anthropoid. Examples of anthropoids are humans, orangutans, and gibbons. The speciation that happened between the small primate and the anthropoids was 65 million years ago. It was during that time that the common ancestors of all primates were still alive.
