If a mutation occurs, leaving 12 bases, the maximum number of amino acids that could be coded for by this DNA segment is 12.
"It is any change in the nucleotide sequence of a DNA."
it is a hereditary material composed of repeating units known as deoxyribonucleotide.
It is a three-nucleotide sequence in a DNA or RNA molecule that together code for an amino acid.

The biomes closest to the Earth's poles are described as polar, characterized by extreme low temperatures and snowy or icy conditions.
Biomes that exist closest to the Earth's poles are described as polar. These cold and harsh biomes include the tundra and ice caps, where temperatures are extremely low and the environment is traditionally snowy or icy. Vegetation in these regions is limited due to the harsh climate conditions. The polar regions are home to animals whose physical characteristics and behaviors have adapted to survive in these extreme conditions, such as polar bears and penguins.

The correct answer is Active transport.
The transportation of molecules against the concentration gradient from the area of its low concentration to high concentration is called Active Transport.The molecular size of vitamins are large so, it is not easy to transport them against the concentration gradient without the help of energy. This energy is in the form of ATP.
Thus, liver uses Active Transport to move vitamins from one area to another area.
b. Sexual reproduction produces larger numbers of offspring in less time.
c. Sexual reproduction produces offspring that have greater genetic variety and durable zygotes that can help green algae species survive unfavorable conditions.
d. Sexual reproduction produces multicellular algae instead of unicellular algae. Multicellular algae are better able to survive harsh conditions.
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.
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.
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.
