According to the graph, we can see that the white cans cool a little bit slower than black cans on the same conditions.
On the first ten minutes, we can see that the temperature of water in black cans decreased from 100°C to 50°C. and the temperature of water in white cans decreased from 100°C to 75°C.
To explain this, you need to know what is a dark and white color?
<span>it's a color in which the total absorption of all wavelengths and none of these wavelengths will be reflected. But since light is a form of energy expression, </span>we can conclude that the black color has no energy on it. on the opposite of the white color, which absorbs all wavelengths, so it has energy on it (which will turn into heat), and that's why it could keep the temperature better than the dark color (all is about energy).
The excretory system is responsible for removing all of the following from the body excep
t
A. Toxic Waste B. Gaseous Waste C. Dissolved molecules D. Cells
Answer:
D. Cells
Explanation:
The excretory system consists of organs that help the body to get rid of excess and waste materials from the body, and also helps in maintaining internal homeostasis in the body. These organs include the large intestine, skin, lungs, kidneys. Most of the wastes are products of metabolism. These waste materials that are no longer useful to the body could be in liquid or gaseous form. Examples of substances removed from the body by the excretory system are urine, feces, sweat etc.
Cells are not part of the substances removed by the excretory system.
Answer:
D) Density of air and humidity levels
Explanation:
Answer: the same amount of DNA normally present in the parent cell
Explanation: somatic cells are diploid and they have the same amount of DNA that their parent cells have
Answer:
Humus (hummus) is a dark organic matter in the soil which is produced by the decay of leaves or twigs (leaf litter). The litter is decayed in the soil by the action of microbial communities and chemcial reactions (together called as biogeochemical reactions). This process is also known as decomposition. The higher humus content in the soil makes it more fertile because there are more nutrients releasing due to increased turnover of the decomposing bacteria. Further, humus formation is increased if more water (moisture content) and oxygen is available.
