We use a prison as an analogy for this. If the gate is open, the prisoners can easily or freely leave the prison cell. This will represent passive transport. In order to get prisoners in the cell, you have to put force on them and this will be active transport.
Answer:
The answer is D.
Explanation:
D, because leaves have serveral areas and functions that allow them to do all of the answers listed, for example, water goes into the roots of a plant and then goes up the stem by capillary action and into the leaves. Leaves can act as storage and carry water throughout the plant if need. Leaves are also a part of the plant in which abosorb sunlight and create sugars through a process known as photosynthesis in order to help the plant use it for consumption.

Answer:
There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection.
Explanation:
Linkage refers to the tendency of inhertance of the DNA sequences that are close together on a chromosome during the meiosis of sexual reproduction. It can be measured by the recombination frequency.
Recombination frequency describes the proportion of recombinant offsrpring produced in a genetic cross between two organisms. It is the frequency with which a single chromosomal cross over takesplace between two genes during the process of meiosis. Recombination frequency (RF) is given by
RF= Recombinants /total offspring x 100.
In the above example, the number of recombinant offspring is 20 and the total offspring is 400. By substituting these values,
RF= 20/400 x100
= 5.
The recombination frequency for the above cross is 5.
