Answer: The correct codon on the mRNA molecule is GUC.

tRNA ( transfer RNA) molecule contains a sequence of three bases in the anticodon loop, which are complementary to the mRNA ( messenger RNA) codon.

mRNA codon codes for a particular amino acid like GUC in this case codes for Valine, which is carried by the tRNA molecule in its amino acid attachment site.

When anticodon matches with the codon in the mRNA, amino acids are assembled in a particular order, which results in the synthesis of protein.

Thus, the codon for the anticodon CAG is GUC.

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.

Final answer:

In this milk-drinking sleep experiment, the independent variable is drinking milk at bedtime, the dependent variable's sleep length, and control variables could include other dietary factors, ambient room temperature, bedtime, etc.

Explanation:

In an experimental design, the independent, dependent, and control variables help us isolate cause and effect relationships. In this case, the independent variable would be drinking a glass of milk before bed. This is the variable manipulated or changed in the experiment. The dependent variable is the length of sleep, as it's believed to be influenced by the milk-drinking behavior. Finally, there are multiple potential control variables - factors kept constant to ensure any changes in sleep length are due to the milk intake and not other variables. Such control variables could include the type and volumes of all other consumables, ambient room temperature, time of going to bed, physical activity levels during the day, etc.

Answer: 6 electrons

Explanation: Oxygen atom has atomic no of 8 which means it has got 8 electrons. n=2 depicts that the electrons have principle quantum no = 2. According to Afbau's rule the electrons are arranged in shells of increasing energy as follows:

Thus there are 2 electrons in 2s and 4 electrons in 2p which makes a total of 6 electrons.

Answer;

D. they have DNA within their nucleus.

Explanation;

-According to evolutionary theory, diverse groups of animals evolve from one or a few common ancestors and the mechanism by which this evolution takes place is natural selection.

-Natural selection is the process by which traits that enhance survival and reproduction become more common in successive generations of a population.

-All forms of life are built of cells. A cell is the basic unit of the structure and function of living things. Living things may appear very different from one another on the outside, but their cells are very similar.
