Which activity combines the use of conduction and convection to transfer heat?

kaheart [24]

<h2>Answer:</h2>

The boiling of water in the iron pan is the activity in which both conduction and convention are used.

<h3>Explanation:</h3>

Energy is transferred from one part of the matter to other part in three ways:

Conduction
Convection.
Radiation.

Conduction is the movement of heat from the collision of the microscopic particles in the matter.

While convection is the transfer from the movement of fluids from one place to another.

In the water boiling activity, the pan is heated by the flame from taking the energy in the collision of atoms in the pan and the energy is transferred into the whole pan and eater molecules. This is conduction while in pan water movement from the bottom to top of pan is by convection.

How has waste leaving a cell affected its surface area to volume ratio?

lapo4ka [179]

The important point is that the surface area to the volume ratio gets smaller as the cell gets larger and as volume increases, surface area to volume ratio decreases. The larger a cell, the less easily it can get rid of waste and it also has more trouble getting water, nutrients and gases in. That is why we do not see giant cells. Instead we see multiple cells in larger organisms.

One way to increase surface area is to flatten the cell. That is why red blood cells are flat discs, instead of spheres. Another way is elongation. That is why many bacteria are rod shaped, and why neurons are elongated. In fact, the human body relies on the same principle to adapt to climate. Long tall and lean folks with long arms and legs live in East Africa, because such shapes increase surface area to get rid of excess body heat to avoid heat strokes. Europeans and Asians adapted to cold climates, in contrast, have shorter arms and legs and rounder torsos to minimize surface area. to conserve body heat.

Describe the experiment, to show that light intensity, water, chlorophyll, and cabondioxide are needed for photosynthesis

lisov135 [29]

Answer:

Is light needed for photosynthesis?

1. Destarch the plant (remove previously made starch from plant)

2. a. cut the leaf in 2

b. 1 part in an opaque box and 1 part in a transparent box (one with light and one without)

3. Test for starch (BEWI)

B. Is carbon dioxide needed for photosynthesis?

1. Destarch the plant (remove previously made starch from plant)

2. a. cut the leaf in 2

b. 1 part in a box with CO2 absorber and 1 part in box with a CO2 provider

3. Test for starch (BEWI)

C. Is chlorophyll needed for photosynthesis?

1. Destarch the plant (remove previously made starch from plant)

2. Use a variegated leaf

3. Test for starch (BEWI)

B E W I

1. Put leaf in boiling water to destroy the cell membrane and denature enzymes

2. Ethanol in a hot water bath to remove chlorophyll

3. Warm water to soften the leaf

4. Add drops of iodine solution

What is stored in carbon

lozanna [386]

BRAINLEST WOULD BE HIGHLY APPRECIATED! :)

It's a part of carbon dioxide gas emitted when fossil fuels are burned and when living organisms breathe. It's in organic matter in the soil, and it's in rocks. But far and away the most carbon on Earth is stored in a surprising place: the ocean.

I hope this helped!!
