Daphnia are freshwater organisms sometimes referred to as “water fleas.” design an experiment that
could be used to test the effects of temperature on the size of a daphnia population. in your
experimental design, be sure to:
• state a hypothesis to be tested
• describe how the control group will be treated differently from the experimental group
• identify the independent variable in the experiment
• identify the type of data that will be collected

Answer

• state a hypothesis to be tested

Development rate increases faster with temperature that growth rate

• describe how the control group will be treated differently from the experimental group

The control group will be raised at 8 different temperatures to assess their size at maturity, and their asymptotic size.

• identify the independent variable in the experiment

3 clonal lines that differ in asymptotic size and growth rate.

• identify the type of data that will be collected

Measurements of the individual length of Daphnia

Explanation

In this experiment, the temperature-size rile(TSR) was utilized where it will be found that responses on temperature size observed at maturity is different from that manifested at asymptotic size. It will be observed that thermal shift in resources allocation may completely or partly result to a thermal plasticity in maturity size. Moreover, it will be seen that thermal plasticity in asymptotic size is controlled by temperature related challenges.

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air

explanation:

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.
