Answer:
One must start with a hypothesis. In this case it is that plant growth is affected by fertilizer.
Explanation:
The dependent variable is plant growth. It is important that the plant are all the same, and there needs to be enough of them to achieve statistical significance. Before hand, You estimate the variability in plant growth and decide what level of significance you want to achieve. For example, you want to draw conclusions with 95% confidence. The independent variable is the fertilizer used ott (over the top) withheld. There needs to be a control group without fertilizer treated exactly as the group with fertilizer.

Which statement about exothermic reactions is true?
Responses
The reactants create energy to form products.
Energy from an outside source is continuously being added.
More heat is given off than is put into the reaction.
The reaction container always feels cold.
Answers
Answer:An exothermic reaction may be defined as a type of reaction in which energy is significantly liberated in the form of heat or light. In such types of reactions, energy is generally transferred into the surroundings rather than utilized from the surroundings.
The option "energy from an outside source is continuously being added" represents an endothermic reaction in which heat or light energy is externally been provided. The option "more heat is given off than is put into the reaction" is not absolutely true because exothermic reactions liberate energy but it does not matter if it is higher or lower than that of being put into the reaction.
Therefore, the reactants have more heat energy than the products is a statement that is true about exothermic reactions. Thus, the correct option for this question is C.
Explanation:
you welcome
Energy from outside sources is continuously being added, since its an exothermic reaction it always focusses on releasing large amount of energy upon activation and combustion.
It cuts off on giving energy back to its surrounding unlike endothermic reaction where the generated energy is given back to the environment to restore its energy levels.
Therefore, it makes it clear that exothermic reaction is a type of reaction that uses combustion to gather the energy lying around in the surrounding to generate large amount of energy and heat and keeps on producing heat until and unless there is energy in surrounding.

E. Temperature does not affect particle motion.
Answers
Lina and Vera purchased fruit pops at the grocery store. The drive home was hot, and the fruit pops turned slushy. Increased temperature means particles have greater motion.
What is temperature ?Temperature is a physical quantity that quantifies our feelings of hotness and coldness. A thermometer is used to measure temperature. Thermometers are calibrated in a variety of temperature scales that have historically been defined by various reference points and thermometric substances.
Temperature is a measure of a system's average kinetic energy. As particles in a matter move faster, their kinetic energy increases, raising the temperature of the system. Heat is defined as the energy exchanged when two bodies of different temperatures come into contact.
The total energy of all molecular motion inside an object is defined as its heat. Temperature is a unit of measurement for the thermal energy or average heat of molecules in a fluid.
Thus, option A is correct.

Answers
Answer:
Seeds
Explanation:
Took the test
An angiosperm is a plant that has flowers and fruits with seed in them.
What is an angiosperm ?Angiosperms are plants that produce flowers and seeds in the form of fruits. With approximately 300,000 species, they are the kingdom Plantae's largest and most diverse group. Angiosperms account for roughly 80% of all known living green plants.
Vascular plants are angiosperms. They are made up of stems, roots, and leaves. Angiosperm seeds, unlike gymnosperm seeds such as conifers and cycads, are found in a flower. Angiosperm eggs are fertilized and grow into seeds in an ovary, which is usually found in a flower.
Another similarity is their ability to produce secondary growth. Angiosperms produce flowers and fruit with seeds within ovaries, whereas Gymnosperms produce seeds in cones.
Thus, An angiosperm is a plant that has flowers and fruits with seed in them.
