Answer: b. the height of the plant.
In an experimental set up an independent variable is the one which can be manipulated or change to observe the effects of such changes or manipulation on dependent variable. For example, plant growth is a dependent variable because it is dependent on independent variables such as amount of sunlight available, amount of fertilizers and water provided.
In this experiment, it is to be determined that how the amount of water given to a plant affects its growth. Here, water is an independent variable which can be change in the experiment and the affect of change can be observed on plant growth which is a dependent variable. A height represents the growth of the plant therefore, height of the plant is the dependent variable.
They are usually made of amino acids.
They lower the activation energy of chemical reactions.
Each one is specific to the particular substrate, or substrates, to which it binds.
Enzymes do not increase delta G of a reaction. Delta G remains the same in an enzymatic reaction. Enzymes fasten reactions by either decreasing the activation energy or by producing binding energy and in both of these cases there is no impact on delta G so it remains the same, that is why statement 1 is incorrect. Statement 2 is correct because most of the enzymes are made up of proteins which is a polymer of amino acids. Statement 3 is also correct because enzymes lower the activation energy as already mentioned. Statement 4 is correct too. Enzymes are very specific to the kind of substrate to which they bind. Enzymes are bond specific, stereo specific & group specific of the substrate to which they bind.
Enzymes are biological catalysts that lower the activation energy of reactions, are made of amino acids, and are specific to their substrates. They do not, however, increase the Gibbs free energy (ΔG) of the reactions they catalyze.
The statement 'they increase the ΔG of reactions' is not true about enzymes. Here 'ΔG' represents the change in Gibbs free energy. In a chemical reaction, enzymes function to lower the activation energy which speeds up the reaction, but they do not increase the ΔG of the reaction.
The other statements about enzymes made of amino acids, lowering the activation energy, and being substrate-specific are true. In essence, enzymes are biological catalysts that speed up reactions but do not change the overall energy change (ΔG).

Parasitic
Competition
Mutualism
Answer: Comensulism
Commensalism is being displayed From the video Clownfish and Sea Anemone Partnership
Explanation:
From the video Clownfish and sea Anemone Partnership there is a significant relation that can be seen from the statement itself too and that is sign of symbolism.
The relation of symbol is used for the sea anemone. So, both Clown fish and Anemone are held to be very beneficial whenever these two fishes are kept together in presence of each other.
So, it can be said clown fish and sea anemone have a very deep relation between each other.

Explanation:
everything must match up inorder to find anyone accountiable
For forensic science, the Gas Chromatography-Mass Spectrometry (GC-MS) is highly reliable and accurate for identifying specific materials. In a case involving a paint chip, it accurately identifies the various elements and compounds in the paint and discriminates between different paint brands and types.
In the entire arsenal of forensic tests, one test stands out for its high reliability and accuracy in identifying specific materials: the Gas Chromatography-Mass Spectrometry (GC-MS). It has two main components: Gas Chromatograph, which separates the different components in a substance, and Mass Spectrometer, which identifies each of these components.
The GC-MS test is particularly effective when analyzing biological materials like blood, saliva, and even paint fragments. When dealing with a case involving a paint chip, for instance, GC-MS can not only identify the various elements and compounds in the paint but can discriminate between different paint brands and types, thereby increasing the probability of accurately matching the paint chip to a specific car.

Bill needs to solve a system of linear equations based on the nutritional content of each food item in order to find out how many cups of rice, tofu, and peanuts he should consume to meet his specific nutritional goals. Keep in mind the caloric density of foods and the importance of a balanced diet.
To determine the number of cups he should eat, we would first need to set up a system of linear equations based on the nutritional content of each food item.
Let's denote R as the number of cups of rice, T as the number of cups of tofu, and P as the number of cups of peanuts. From the information given, we can create these equations:
42R + 4T + 34P = 350 (for carbohydrates)
0R + 11T + 75P = 311 (for fats)
1R + 23T + 35P = 168 (for proteins)
He needs to solve this system of equations to get the values of R, T, and P. Keep in mind, nutritional goals are important but it's also vital to consume foods high in micronutrients, fiber and have a balanced diet. Remember that fatty foods are calorie-dense compared to carbohydrates and proteins, meaning they have more calories per unit mass. This can be a healthy and sustainable meal plan for Bill if he also incorporates sufficient fruits, vegetables, and exercises regularly.

b. crustaceans
c. zooplankton
d. sponges
The creatures that do not gain energy from marine snow either directly or indirectly are known as Zooplanktons. Thus, the correct option for this question is C.
Zooplankton may be defined as an organism that is small floating or weakly swimming in nature anddrifting with water currents and, with phytoplankton, making up the planktonic food supply upon which almost all oceanic organisms are ultimately dependent.
The creatures of zooplankton are ultimately deriving their energy by consuming phytoplankton. So, among the options given, they are the creatures that do not gain energy from marine snow either directly or indirectly. While rays, crustaceans, sponges, etc. gain energy from marine snow either directly or indirectly.
Therefore, the creatures that do not gain energy from marine snow either directly or indirectly are known as Zooplanktons. Thus, the correct option for this question is C.
