What else can I help you with?
True or false fine hairlike extensions on the exposed or free surfaces of some cells are called microvilli?
True. Microvilli are fine hairlike extensions on the surface of some cells that increase the cell's surface area for absorption and secretion.
What does microvilli do in a cell?
Microvilli (singular: microvillus) are microscopic cellular membrane protrusions that increase the surface area of cells. They are involved in a wide variety of functions, including absorption, secretion, cellular adhesion, and mechanotransduction.
What is going to happen to the pH when elodea is exposed to light?
The pH of the water will increase when elodea is exposed to light. This is because during photosynthesis, elodea will take in carbon dioxide, which will result in a decrease in carbonic acid concentration, leading to an increase in pH.
What is surface area in plants?
Surface area in plants refers to the total area of all surfaces exposed, such as leaves, stems, and roots. Surface area is important for functions such as photosynthesis, gas exchange, and absorption of water and nutrients. It affects the plant's ability to interact with its environment and perform essential biological processes.
Does increasing the surface area increase or decrease the rate of a chemical reaction?
It will increase the rate of the reaction because more particles will be exposed and they will be able to react.This decreases the time to react.
True or false fine hairlike extensions on the exposed or free surfaces of some cells are called microvilli?
True. Microvilli are fine hairlike extensions on the surface of some cells that increase the cell's surface area for absorption and secretion.
What increases the surface area of certain epithelial tissues?
microvilli, tremendously increase exposed surface area in epithelial tissue.
How are light surfaces and dark surfaces affected by the suns energy?
Light surfaces reflect more sunlight, which can help to keep them cooler compared to dark surfaces that absorb more sunlight and thus become hotter. This difference in absorption and reflection of solar energy can lead to variations in temperature between light and dark surfaces when exposed to sunlight.
What happens to the rate at which a rock will weather when it is broken up and why?
The rate of decomposition of the rock will increase when it is broken up because there is more surface area exposed to the elements weather) that can erode the surfaces.
Why is radiation of heat larger in a black surface than a white surface?
Black surfaces absorb and emit more radiation across a wider range of wavelengths compared to white surfaces, which reflect more radiation. This difference in absorption and emission rates leads to black surfaces becoming hotter than white surfaces when exposed to radiation.
How can color affect surface temperature?
Color affects surface temperature through absorption and reflection of light. Darker colors absorb more light and heat up more than lighter colors, which reflect more light and heat. This can result in darker surfaces becoming hotter than lighter surfaces when exposed to sunlight.

What is ozonated magnesium oxide and how does it differ from traditional magnesium oxide supplements?
Ozonated magnesium oxide is a form of magnesium oxide that has been exposed to ozone gas. This process is believed to increase the bioavailability and effectiveness of the magnesium. Traditional magnesium oxide supplements are not exposed to ozone gas and may have lower absorption rates in the body.
How does abrasion change the desert surface?

What do you call the total area of exposed surfaces on a geometric solid?
Surface area
What experiment can you use to find which surfaces are better absorbers of heat?
You can conduct an experiment using different materials (e.g. metal, wood, plastic) exposed to sunlight and measure their temperature increase over time. The material that shows the highest temperature rise is a better absorber of heat. Alternatively, you can use a heat lamp and measure the temperature increase on different surfaces to determine which one absorbs heat more efficiently.
What does light absorption require the presence of?
Light absorption requires the presence of a material that is capable of absorbing light energy. This material typically contains atoms or molecules that can undergo a transition of electron energy levels when exposed to light, resulting in the absorption of photons.
