Answer:
I and III only
Explanation:
Crop rotation is a farm practice that involves cultivating different species of crops on the same land at different seasons. In other words, the different crops are rotated. Crop rotation is done for various reasons including; improvement of soil fertility, pest and disease control etc.
In this case, a crop rotation of various grains and legumes would be an appropriate solution for the following problems:
- The nutrients in the soil on a farm are being depleted: Legumes are known to be rich in nitrogen and hence add nitrogen to the soil due to the nitrogen-fixing microbes in their roots. Hence, rotating between grains and legumes can help return the depleted nutrients (by grains) to the soil.
- A particular kind of pest is infesting the soil on a farm: Most pests are usually crop-specific, hence, planting only one type of crop can make that soil be infested with a particular kind of pest. However, rotating between crops such as grains and legumes can make a particular pests become scarce or less populated.
Answer 1: A. Basic
Answer 2: 1. Cell
Answer 3: O. Organ
Hopefully this helps!! (:
They have combined together to create mass forms of things such as the desk you may be using or the paper you are writing on.
The independent variable would be temperature, the dependent variable would be planted height/number of leaves, and all other factors would be constant variables in an experiment to find the temperature at which beans sprout the quickest.
<h3>What would be the variables, If you were running an experiment to determine the temperature at which beans sprout the fastest?</h3>
- The independent variable would be temperature, the dependent variable would be planted height/number of leaves, and all other factors would be constant variables in an experiment to find the temperature at which beans sprout the quickest.
- The modified variable used in the study serves as the independent variable. Different planted beans would be exposed to various temperatures to discover the temperature at which they sprout the quickest. As a result, in this situation, the temperature is acting as the independent variable.
- The variable measured during the study whose value depends on the given controlled variable is known as the dependent variable. In this situation, the beans' growth would vary according to the temperature they are permitted to grow in. Thus, the dependent variable would be growth indicators like height, leaf count, etc.
- The variables that are maintained constant throughout all subject groups during the study process are known as controlled or constant variables. Conditions should be maintained constant for all participants, excluding the independent and dependent variables. These all fall under the category of controlled or constant variables.
