Answer:
After 48 hours amount left = 6.25 g
Explanation:
Given data:
Half life of potassium = 12 hours
Total mass = 100 g
Mass left after 48 hours = ?
Solution:
Number of half lives passed:
Number of half lives = Time elapsed / half life
Number of half lives = 48 hours/ 12 hours
Number of half lives = 4
At time zero = 100 g
At first half life = 100 g/ 2 = 50 g
At 2nd half life = 50 g/2 = 25 g
At 3rd half life = 25 g/2 = 12.5g
At 4th half life = 12.5 g/2 = 6.25 g
It would not be plants, even though it has cell walls. They are not made of chitin. Plants are also not heterotrophic.
Fungi, however, decompose other matter, and have cell walls made of chitin. This would fit the description.
Answer:
population that is unchanging
Explanation:
Homeostasis is the natural state of equilibrium; the body attempts to maintain this equilibrium by constantly reacting to external forces that attempt to disrupt the fine balance. It involves the maintenance of the internal environment constant, this involves conditions such as blood sugar, body temperature, among other factors that enhance functions in the body. Through homeostasis organisms tend to resist changes in order to maintain a stable, and a constant internal environment.
Answer:
Explanation:
Yes, for a couple of reasons.
1. Carbon connects easily with other carbons.
2. Carbon forms chemical that can change and connect with other carbons even in biology or especially in Biology. If you take a brown seen and plant it where it can get water and soil nutrients, to will come up as a green plant. Think about the chemistry that goes into that. Not only that, but there are mechanisms that tell the upper part of the plant that the roots can't supply any more growth. Isn't that something? All made from Carbon.
3. The human body is a mass of Carbon based chemicals and all cells there can have different functions. Amazing isn't it? I'm a fan of the diversity of our planet and its growth.
