Answer:
Messenger RNA (mRNA)
Answer:
Adhesion and cohesion
Explanation:
Capillary action refers to the ability of water to move in small-diameter or narrow tubes against the force of gravity. Water has a tendency to form hydrogen bonds with other water molecules.
Intermolecular hydrogen bonding allows the water molecules to stick together. This tendency of water molecules to stick together is called cohesion. Adhesion is the ability of the water to stick to other substances with polar or charged groups. As a consequence of cohesive and adhesive properties, water exhibits capillary action. When water moves through microscopic spaces present between the soil particles towards the roots, it is capillary action.
A. number of pots
B. amount of water
C. amount of phosphate
D. amount of blooms on a plant
Answer: B. amount of water.
Explanation: Controlled variables are those that remain constant in an experiment in order to avoid misconclusion about the relation between the dependent and independent variables.
Dependent variables are those that rely on other variables and independent variables are the ones that the experimenter controls.
In this case dependent variable is the production of blooms because depends on how much phosphate is added, so independent variable is the amount of phosphate.
Control variable is amount of water because it affects the growth and production of plants but when the experimenter use the same amount in both trials is standarizing the effect and making non-relevant to the study.
2. location of earthquakes
3. rain forest depletion
4. the shape of the continents
Rain forest depletion is not evidence of plate tectonics.
• Plate tectonics is responsible for the distribution of fossils on distinct continents, for the continental and ocean floor features comprising volcanoes, mountains, trenches, and faults, for the occurrence of earthquakes, and the shape of the continents.
• On different continents, the fossils are identical to the fossils found on the continents, which were once connected.
• The majority of the oceanic and continental floor features are the outcome of the earthquake and geological activity along the plate boundaries.
• The depletion of rainforest is not a result of plate tectonics. The major reason for rainforest depletion are agriculture and fuelwood collection.
• Apart from this, some of the human activities like logging, mining, development of large dams and industry is also major cause of rainforest depletion.
Thus, rainforest depletion is not evidence of plate tectonics.
