The three things Volvox lack is Organs, Organ System, and muscles.

This is the most complex level of organization in life. several Volvox, one of the simplest multicellular living things. Volvox has no tissues.

In the northern region, the eyespots are more developed. This helps the colony to swim towards the light. This differentiation of cells makes Volvox quite unique. It is a colony that comes really close to being a multi-celled organism.

Volvox is a freshwater alga that is found in ponds, ditches, and even in shallow puddles. Volvox is nothing but a chlorophyte or green algae which exists as a grand spherical colony. Each little algae within the colony hold two flagella, whip-like hair.

Titín is the largest know protein with the greatest number of animo

The largest known protein with the greatest number of amino acids is titin.

Titin or connectin  is a largest protein  in humans which is encoded by the TTN gene, having greater than 1 µm in length and it functions as a molecular spring  responsible for the passive elasticity of muscle.

It consist of 244  folded protein domains connected by unstructured peptide sequences, when the protein is stretched, the domains will unfold.

Titin protein involve in the contraction of striated muscle and connected  the Z line to the M line in the sarcomere, contributes to force transmission at the Z line.

It limits the motion range of the sarcomere during tension,  so it involve in the contribution of  passive stiffness of muscle, it is the third most abundant protein in muscle after myosin and actin.

Graduated cylinder

Explanation:

Measuring devices are used as follows -1. Thermometer, 2. Heart monitor, 3. Measuring cylinder, 4. Clock, 5. Tape measure

The instruments that are used for the measurements of various specific items based on the laws and the theories of measurement are called measuring devices.

Specific measurements have specific measurement devices. These measure the value based on the specific unit of the measurement.

For example, an inch tape measures the length of something in inches. It also has scales of centimetres and meters.

For the measurement of length, scales and tape measures are used.

For the measurement of time, clocks are used.

For the measurement of volumes, graduated cylinders are used.

For the measurement of temperature, thermometers are used.

Therefore, the measuring devices vary according to the function it needs to perform. In this case, 1. Thermometer, 2. Heart monitor, 3. Measuring cylinder, 4. Clock, 5. Tape measure.

Hypothesis: The soil in the flat part of the field has less fertility than the soil on the small hill.

Experiment:

The experiment will be carried out in a greenhouse, to promote a controlled environment and equal to all plants used in the treatment.

In this experiment, the influence of the difference in fertility of the soil samples, in the flat part of the land and in the most inclined part, in the germination and growth of corn plants will be tested.

Corn seeds of the same species will be selected. All seeds will be sanitized and will go through the same dormancy breaking process, so that all of them have their germination stimulated.

Vessels with a capacity of 30 kilos will be caught. These pots will be cleaned, sterilized and filled with the same amount of soil collected in the field and with two corn seeds. It will be used 10 pots with soil that was collected in the flat part of the land, 10 pots with soil from the sloping part of the land and 10 pots with fertilized substrate containing high levels of fertility.

The pots will be placed in a greenhouse and will be irrigated with distilled water, to avoid contamination by possible substances in the water.

The pots will remain in the greenhouse for 100 days, where the behavior of seeds and plants in each of them will be observed and noted. After this period, a comparison will be made between the vessels of each treatment, assessing the differences between them and reaching the conclusion whether the hypothesis is true or false.

Independent variable: the amount of caffeine  

Explanation:

The dependent variable is the variable being measured or tested in a given study, while the independent variable isn't changed by the other variables. In this case, the heart rate is dependent on the amount of caffeine, which is then the independent variable. The experimental groups are the groups exposed to the independent variable.

Hydrophobic substances such as vegetable oil are nonpolar substances that repel water molecules.

Nonpolar substances are molecules that do not have a charge separation between different parts of the molecule. This means that they do not have a polar, or electrically charged, end, and as a result, they do not dissolve well in polar solvents like water.

Nonpolar substances are hydrophobic, meaning that they repel water molecules, and tend to dissolve in other nonpolar substances, such as oils and fats. Examples of nonpolar substances include hydrocarbons like gasoline, fats, oils, and waxes, as well as some gases, like nitrogen and methane. Nonpolar substances play an important role in a variety of biological and industrial processes, and their unique properties make them useful for many different applications.

8. kwashiorkor

Explanation:

1. ANTIBODIES are proteins that aid the immune system in its fight against bacteria, viruses, and other foreign substance by binding to them and helping to inactivate or destroy them.

2. HORMONES are substances made of protein or lipid released into the bloodstream in order to direct physiological activity in the body.

3. A high-protein diet can increase the risk of KIDNEY STONES because the body will have an increased acid level.

4. TRANSPORT PROTEINS carry many substances through the blood or allow movement of substances in and out of cells.

5. PROTEIN-ENERGY MALNUTRITION is the phenomenon used to describe an inadequate intake of proteins and/or calorie content.

6. COENZYMES are molecules that play vital roles in the function of an enzyme. Coenzyme in form of vitamins are utilized by enzymes to catalyze chemical reactions.

7. Proteins can act like BUFFER (a substance with a stable pH) in order to regulate the acid-base balance in the body.

8. KWASHIORKOR is a malnutrition deficiency that result from the insufficiency of dietary protein, resulting in swelling in the feet, legs, and stomach among other symptoms.

Assuming you meant melts and not ments (if it was the latter, I have no idea what you mean), the answer is False. The melting point is when the substance melts, turning from a solid to a liquid. On the other hand, the boiling point is when the substance turns from a liquid to a gas.
