Do humans need enrichment? Ultimately for humans, enrichment needs to make us feel valued and good about the contribution we are making. As with animals, there is not one form of enrichment that works for all. What is the primary source of enrichment for rats? For rats and mice, I place high-fiber rabbit food in […]
Is 30 minutes of cardio a day enough to lose weight?
Is 30 minutes of cardio a day enough to lose weight? A new study shows 30 minutes of exercise a day works just as well as an hour in helping overweight adults lose weight. Can you burn fat without cardio? That’s right – you can cut without doing traditional cardio. There’s no denying that sprints […]
What are 3 factors that affect precipitation?
What are 3 factors that affect precipitation? Three factors that might influence the occurrence of precipitation are moisture supply, frontal position and atmospheric instability. Moisture supply: A rule of thumb is that when the relative humidity reaches or exceeds 70% at 850 mb (around 1,500 meters or 5,000 ft. What four factors affect a region’s […]
Are heat and temperature inversely proportional?
Are heat and temperature inversely proportional? (a) The amount of heat transferred is directly proportional to the temperature change. To double the temperature change of a mass m, you need to add twice the heat. (c) The amount of heat transferred depends on the substance and its phase. How will the difference in temperature of […]
Why are rabbits r-selected species?
Why are rabbits r-selected species? So this begs the question are rabbits truly prolific, and why? In Page 2 the 1960s two ecologists came up with r/K selection theory. It relates to parental investment and reproductive strategies adopted by species in order to advance its kind into the future. And they have the ability to […]
How many times will I be writing 2 if I write down numbers from 11 to 99?
How many times will I be writing 2 if I write down numbers from 11 to 99? How many times will I be writing 2 if I wrote down numbers from 11 to 199? Solution: From 11 to 100, count numbers such as 12,32,42,52,62,72,82,92 which are 8 in numbers plus numbers from 20,21,22,23,24,25,26,27,28,29, have digits […]
What are the two main types of energy?
What are the two main types of energy? Many forms of energy exist, but they all fall into two basic categories: Potential energy. Kinetic energy. What are the two types of mechanical energy? There are two main types of mechanical energy. They are motion energy and stored mechanical energy. Motion energy: This is the energy […]
What are examples of fast chemical reactions?
What are examples of fast chemical reactions? Chemical reactions that complete in a very short time, such as less than 10 -6 seconds, they are called fast reactions. Examples: Magnesium ribbon is burnt in the flame of Bunsen burner; it quickly gets combusted with a noticeable spark. Similarly, a neutralization reaction between acids and bases […]
What is the relationship between wavelength and speed?
What is the relationship between wavelength and speed? Speed = Wavelength x Wave Frequency. In this equation, wavelength is measured in meters and frequency is measured in hertz (Hz), or number of waves per second. Therefore, wave speed is given in meters per second, which is the SI unit for speed. What is the longest […]
Can 2 angles be supplementary if both of them are obtuse?
Can 2 angles be supplementary if both of them are obtuse? As we know that obtuse angle is always greater than 900. So, the sum of two obtuse angles always makes greater than 1800. ∴Sum of two obtuse angles cannot make a supplementary angle. Can two angles be supplementary if both of them are? Thus, […]
