3. Three redwood trees are kept at different humidity levels inside a greenhouse for 12 weeks.

One tree is left outside in normal conditions. The heights of the trees are measured once a

week.

IV humidity levels

DV height

CG tree left outside

Answers

Answer 1

Answer:

This question is asking to identify the following:

Independent variable: Different humidity levels

Dependent variable: Height of the plant

Control group: Tree left outside in normal conditions

Controlled variable: same time of measurements (once in a week), same types of trees

Explanation:

Independent variable is the variable that the experimenter changes or manipulates in an experiment. In this experiment, three redwood trees are kept at different humidity levels. Hence, the independent variable is the DIFFERENT HUMIDITY LEVELS the redwood trees were kept at.

Dependent variable is the variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this case, the HEIGHTS of the trees measured is the dependent variable.

Controlled variable or constants are those variables that must be kept unchanged throughout the experiment for all groups. In this experiment, the constants are: same time of measurements (once in a week), same types of trees (redwood).

Control group is the the group in an experiment that does not receive experimental treatment. In this case, the group that does not receive treatment/control group is: Tree left outside in normal conditions.

What does it mean to move UP the concentration gradient?

Answers

Answer:

Moving against the concentration gradient, or in simpler terms, moving from a low-concentration area to a high-concentration area.

Explanation:

This action uses energy, as according to entropy, the substance will move from a higher concentration to a lower concentration, and cells have to put extra energy to pump the molecules / substance up the concentration gradient.

It is mostly used to trigger chemical responses in cells, like in neuron synapses.

Place the next two tRNA molecules on the mRNA strand. What happens?

Answers

Answer:

Required Answer:-The tRNA left the ribosome. The amino acids stayed and the mRNA partially left the ribosome.

If place the next two tRNA molecules on the mRNA strand, the amino acids shifted to the next tRNA molecule.

 

How are tRNA molecules involved during protein synthesis?

tRNA departed from the ribosome, while the mRNA partially exited the ribosome, the amino acids remained. While a tRNA molecule separates from the mRNA and leaves the ribosome, the neighboring amino acids join with one another.

The ribosome adds the amino acid carried by each tRNA molecule to the lengthening amino acid chain as it attaches to the mRNA.

The polypeptide chain is once more transferred to the new tRNA, the empty tRNA is released, and the ribosome ratchets through the mRNA by three further nucleotides while also shifting the tRNA.

Therefore, the ribosome and the mRNA are drawn to a tRNA whose anticodon is complementary to the next codon in the mRNA.

Why can a planet orbit circular?

Answers

Answer:

Explanation:A circle is merely a special case of an ellipse. However, the planets do not quite move in ellipses either.
