I think because humans have sweat glands in their skin that help cool the body by evaporation. Dogs don't have sweat glands but they have extensive blood vessels in their tongues that allow for heat to transfer. Panting helps move air across the tongue which carries away heat from the dog's blood.
Explanation:
1) Chemical digestion begins in the mouth when food mixes with saliva. Saliva contains an enzyme (amylase) that begins the breakdown of carbohydrates.
2) The daily values are reference amounts (expressed in grams, milligrams, or micrograms) of nutrients to consume or not to exceed each day. The %DV helps you determine if a seving of food is high or low in a nutrient.
3) If a food has a daily value of 5% or less of a nutrient, it is considered to be low in that nutrient.
A food is a good source of a nutrient if the percent daily value is between 10% and 19%, If the food has 20% or more of the daily value, it is considered an excellent source of that nutrient.
4) As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body.
5) During digestion, your pancreas makes pancreatic juices called enzymes. These enzymes break down sugars, fats, and starches. Your pancreas also helps your digestive system by making hormones. These are chemical messengers that travel through your blood.
Glad to help!!!!
<span>True.
Earthquakes are felt whenever there is a slip around a fault in the rocks below the earth. This reorientation of faults create sesmic waves and is known as earthquake, the severity of which is measured in richter scale. These are more prominent in hilly regions as the rocks usually form faults to balance the pressures on it.</span>
not sure what you mean, but I think you're talking about the bonds i suppose. Anti-parallel strands are connected by H-bonds, whereas the sugar and phosphorus are bonded by covalent phosphodiester bonds.
Answer: Light goes into the eye via the cornea, it then pass through the pupil, the lens, the vitreous humor and finally forms an image on the retina.
Explanation:
Light goes into the eye via the cornea. The cornea is a clear, dome-shaped surface that covers the front of the eye.
From the cornea, the light passes through the pupil. The pupil regulates the amount of light passing through.
From the pupil, , light hits the lens. The lens is the clear structure inside the eye. It focuses light rays onto the retina.
Subsequently, light passes through the vitreous humor. A clear, jelly-like substance that fills the center of the eye. It helps to keep the eye round in shape.
Finally, the light reaches the retina where the image is formed the image is usually inverted. The retina is a light-sensitive nerve layer that is situated at the back of the eye.
The main function of the optic nerve is to carry the signals to the visual cortex of the brain. The visual cortex turns the signals into images.
