Answer:
The height to which to tomato plants grow
Explanation:
In an experiment, the dependent variable is the variable that the experimenter measures. It is the variable that responds to changes made to the independent/manipulable variable.
According to this question, students investigate how soil pH affects the height of tomato plants. The different pH each plant receives is the independent variable while the HEIGHT OF THE PLANTS that responds to the soil pH or that is measured by the students is the DEPENDENT VARIABLE.
The question is incomplete. The complete question is:
Plasmodesmata are cell junctions that are found between ________.
a) adjacent animal cells in the same tissue type
b) individual cardiac cells in heart muscle tissue
c) the plasma membrane of actively dividing prokaryotes
d) adjacent plant cells
Answer:
d) adjacent plant cells
Explanation:
Plasmodesmata are the cytoplasmic channels that connect the adjacent plant cells together and maintain the continuity of their cytoplasm. These are the narrow channels with 20-40 nm diameter. Plasmodesmata serve the function analogous to the gap junctions of the animal cells. The presence of plasmodesmata between the neighboring plant cells allows the movement of molecules and ions between them. Plant cells can adjust the diameter of the plasmodesmata according to the requirement to allow the transport of substances across them.
Answer:
Food refers to any nutritious substance whereas diet refers to the food eaten by organisms daily.
Explanation:
1. Food refers to any nutritious substance that an organisms eat in order to survive and maintain growth whereas diet refers to the sum of food that is consumed by an organism.
2. Malnutrition refers to a condition that occurs from eating a diet which does not supply a healthy amount of nutrients to our body whereas hunger refers to a feeling of discomfort that is caused by lack of food.
3. No, it is not possible to be over-nourished and under-nourished at the same time because a person can attain one condition at a time whether he can be over-nourished or under-nourished.
4. The three elements of food security are availability, access and consumption of food. Availability of food means having sufficient quantities of nutritive food available to a person, access means having sufficient resources to have access to the food and consumption means having taking sufficient amount of nutrients and the ability to absorb and use nutrients in the body.
