Answer:
B. The light waves get "stretched out" as they travel.
C. The light waves appear redder than expected.
Explanation:
You might hear about doppler effect before. An ambulance siren will be heard differently when it coming to you and when it moves away. When moving away, the frequency of the sound will seem to keep getting lower to the observer. A lower frequency means the sound appear to have a longer wavelength.
When scientist examines the lightwave from the distant stars, they find that the light wavelength seems stretched out and then it should be. The light also seems redder than expected. Redder light means the wavelength is longer, so the object should move away from our observation point.
C. Perspiration and expiration.
Explanation – Insensible water loss is the type of loss which can't be felt like loss through perspiration or sweat and evaporation loss from the respiratory tract which is expiration. Sensible water loss is mainly urine which is released under our senses like see, feel and measure.
Insensible water loss is around 500-650ml/day according to some sources. There are certain factor that affects insensible water loss and are : temperature of the environment, humidity, altitude etc.
The human skin is the protective layer of the human body against the external forces like the temperature, sharp objects, microbes, fungi and other related materials that can penetrate and weaken the body however, the integumentary system prevents any harm come to the organism. The dermis is the skin area which has different structures that perform different functions.
A Tomatoe is botanically and scientifically a fruit because it contains the ovary and the seeds of a flowering plant. It is a fruit even although it is used as a vegetable , but since the Supreme Court in the Nix vs Hedden case in 1893 unanimously decided that customs regulations should classify tomatoes as a vegetable instead of a fruit for taxation purposes,
so the answer would be tomatoes are considered vegetables
Answer:
Hello. You did not enter the answer options, but the factor that most directly influences a measurable result in an experiment is the manipulation of the variables.
Explanation:
In an experiment, the manipulation of variables becomes highly important so that it is possible to measure, that is, evaluate the result. This is because it is the variables that express values that represent the characteristics that are being analyzed and studied within the experiment. Therefore, the manipulation between them must be done in a very rational and balanced way so as not to modify the values shown by them, changing the data and generating false or immeasurable data.
