The right answer is Filtration.
A water filter is composed of a filtration system that aims to separate the water from the solid particles (residues) by passing it through a porous medium, which allows only the liquids and the finer solid particles to pass through. as the filter holes (porosity). The water that comes out of this filtration system is rid of solid particles larger than the pores of the filter.
Some water filters are designed to make drinking water (very fine filtration, less than the size of a microbe).
Answer:
Since Yellow is dominant over green then almost all of the children will have yellow faces. The punnet square below will show what the offspring will have but my guess is
50% will have yellow faces
50% will have both yellow and green
1% will have a green face
But since Yellow is dominant over green the 50% of both colors will mostly show a yellow dominant.
I apologize if my drawing looks messy.
Hope this is correct
Answer:
You missed the specific heat on water, that is 1 calorie/gram °C. This answer is, 0.12°C
Explanation:
The stayment says, that all of the energy from the pancake is transferred into the water, so we have to think that 61 calories are burned in the calorimeter with water. Let's apply on the formula.
Heat added = specific heat x mass x (tfinal - tinitial)
61 cal = 500. g .1 cal/g °C . ΔT
61 cal / 500 g / 1 cal/g °C =ΔT
0.12 °C = ΔT
The correct answer is diffusion.
Aquatic respiration refers to the procedure whereby an aquatic animal attains oxygen from water. Fish and other aquatic species utilize gills to consume oxygen dissolved in the water and diffuse carbon dioxide out of the bloodstream.
Diffusion is a procedure in which a substance moves from a region of high concentration to the region of low concentration until equilibrium is attained. In the case of aquatic species, blood with a low concentration of oxygen molecules moves through the gills. The concentration of the oxygen molecules in water is greater in comparison to the concentration of oxygen molecules in the gills.
As a consequence, the molecules of oxygen diffuse from water (higher concentration) to a region of lower concentration, that is blood. In the same manner, the molecules of carbon dioxide diffuse from the blood, that is, high concentration to water, that is, low concentration.
