Would you expect the stomata of a desert cactus or the stomata of a water lily plant to close during the day?

Answers

A water lily will have more stomata. A desert cactus will have very few stomata, because in deserts plants face water shortage so in order to avoid loss of water cacti have adapted to the desert environment by possessing few stomata.

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.

Convection occurs because heated material becomes ____________________. A less dense and rises B denser and rises C denser and sinks D less dense and sinks

Answers

Answer: A less dense and rises

Explanation:

Convection is a type of heat transfer happens when there is a movement of fluid (liquid or gas) in which convection currents are produced due to the movement of hot fluid upwards and cold fluid downwards. This happens as the density of hot fluid decreases due to presence of less number of mmolecules per unit volume. As the hot liquid becomes less dense, it starts moving upwards.

Thus convection occurs because heated material becomes less dense and rises.

which cells divide more often than other cells?

Help

Answers

That means we lose around 50 million cells every day. This is a lot of skin cells to replace, making cell division in skin cells is so important. Other cells, like nerve and brain cells, divide much less often.

Skin cells need to divide as you grow. Hair follicle cells divide to produce more hair. Your lining cells (ex: stomach) and intestinal wall cells need to divide to provide new surfaces. Some cells like blood cells, nerve cells, and muscle cells do not divide after some time.

According to the data in the table, what percent of the elodea cells is water? Explain how you arrived at this conclusion.

Answers

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.

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.
