Answer:
By designing an experiment where the temperature on the thermometer is measured after a chosen (same) time interval when the thermometer is wrapped with the different materials and placed in the freezer
Explanation:
Experimental design
Materials given: freezer, a thermometer, samples of materials
setup:
1. The freezer is put on and made to remain at a particular temperature, mimicking the winter season.
2. Next, different materials for the coat design with equal dimensions are used to rap the thermometer whose initial temperature has been recorded in the same pattern and the thermometer is placed in the freezer and left for a certain time, which is made constant for the different materials.
3. after the time, the final temperature on the thermometer is recorded.
Result interpretation
The temperature is expected to drop after the time in the freezer, but the material with the smaller change (drop) in temperature indicates that it traps more heat hence is the best material for designing a winter coat
independent variables: type of material used
dependent variables: temperature on the thermometer
control variables: time, dimensions of materials, temperature of freezer, pattern of wrapping.
The esophagus then releases the food into the stomach and a valve, or sphincter, acts as a gateway to keep the food from going back up into the esophagus. Stomach. In the stomach, our food is sterilized and further broken down.
It will get lower since the pressure around the barometer gets lower
The eye convergence effect allows you to see only one image of nearby objects. Mydriasis is the dilation of the pupil when you reduce light or see into the distance.
<h3>Describe the structure of the human eye.</h3>
Each eye constantly adjusts the amount of light it receives, focusing on both near and far objects, producing a continuous image that is instantly transmitted to the brain. The orbit is a cavity of bone that contains the eyeball, muscles, nerves, blood vessels, and structures that produce and drain tears. The eyeball is made up of three layers, including the optically transparent aqueous humor, the lens, and the vitreous.
- The outermost layer consists of the cornea and sclera.
- The middle layer contains the main blood supply of the eye.
- The inner layer consists from back to front of the choroid, ciliary body and iris.

Answer:
Step 1
The plant takes in carbon dioxide in the atmosphere through the stomata on its leaves. It is worth noting that there are some stomata on the stems as well.
Step 2
Water gets into the plant mainly through the roots and finds its way to the leaves, where photosynthesis occurs. Plant roots are specially designed to draw water from the ground and transport it to the plant leaves through the stem.
Step 3
Chlorophyll, the green coloring matter of the leaf, traps the energy from sunlight as it shines on the leaf. It is worth noting that it is chlorophyll that gives the leaf its green color.
Step 4
The solar energy is used to break water down into hydrogen and oxygen. Then hydrogen is combined with carbon dioxide to make sugar, which is food for the plant. Oxygen is released as a byproduct through the stomata.
