Answer:
B. stomata.
Explanation:
Stomata are openings in the surface of the plant epidermis through which gases and water vapor pass. They are formed by two elongated cells whose shape is similar to bean grain or dumbbell depending on the species. These cells are called guard cells, and in their midst there is a slit called the ostiole.
The stomata make the exchanges between the external and internal environment of the plant. They regulate the size of the opening, so it is possible to increase or decrease the rate of perspiration of the plant.
Stomata are usually located at the bottom of the leaf, but in aquatic plants such as the water lily they are at the top and still in vertical growing plants on both sides.
Scientists are able to understand the earth's interior by studying these seismic waves. They are waves of energy that travel through Earth, and actually move similarly to other types of waves, like sound waves, light waves, and water waves.
It’s quite interesting because
they give out lots of useful information.
But really this only scratches the surface on what they can do!
Happy to help!

Answer: random changes in allele frequency
Explanation:
Which division in meiosis is more similar to mitosis? In which division do sister chromatids separate from each other?
Meiosis I; Meiosis 2
In Meiosis I, it is just like the phases of Mitosis:
Prophase
Metaphase
Anaphase
Telophase.
In Meiosis 2, it is also the same, but the DNA is not replicated. Instead the chromatids are pulled apart and you are left with 4 gamete cells.
