ganyan rin sagot ko sa module ko
When a gas obeys Boyle's law, the temperature is held constant. The correct option is C.
What is Boyle's law?Boyle's law is given by Charles Boyle. It is a gas law that states the pressure decrease with the increase in the volume and the temperature remain constant. In other words, the pressure exerted on gas is inversely proportional to the volume of the gas.
The law shows the relationship between pressure and volume, with the temperature remaining constant. There are three gas laws which are given by different scientists. These laws show the relationship between two variables and the third remains constant. These variables are temperature, volume, and pressure.
Thus, the correct option is C. temperature regarding the gas obeys Boyle's law, and it remains constant.

Which is required for sexual reproduction
Answer:
meiosis
Explanation:
meiosis is used to produce gametes for sexual reproduction
Answer:
Meiosis, and female and male

Sexual reproduction is a reproduction that requires a male and a female of the same species to contribute genetic material. Special cells called gametes are produced through meiosis, which halves the number of chromosomes in each resulting cell. These cells are called haploid gametes.
Would you expect the stomata of a desert cactus or the stomata of a water lily plant to close during the day?
The stomata of a desert cactus will close during the day.
STOMATA:
The stomata (singular- stoma) are structures on the leaves of a plant that helps in gaseous exchange i.e. entry and exit of CO2 and O2 gases. The stomata, however, when opened allows the passage of water vapor from the plant. Hence, plants utilize the opening and closing of stomata to regulate water loss. Desert cactus is a xerophytic plant meaning that they can survive in low water conditions. One way they adapt to their desert environment, which is characterized by low humidity, is by the closure of their stomata during the day. Therefore, the stomata of a desert cactus will close during the day.Learn more at: https://brainly.com/question/3387375?referrer=searchResults

According to the data in the table, what percent of the elodea cells is water? Explain how you arrived at this conclusion.
Answer:
99%
Explanation:
at a salt solution concentration of 2%, plasmolysis first started to occur. So the other 98% in the "solution" would have just been water. Since water inside cells needs to be greater than the amount of water outside the cells, we can say that the amount of water inside the elodea cells was 99% so that it can allow hypertonic plasmolysis to occur.
