Answer: Under normal ambient conditions water is less dense as a solid than as a liquid, so ice floats on water. Most materials are more dense as solids.
Explanation: When water freezes, the molecules do not stack into a close-packed structure. They form a relatively open, honeycomb-like arrangement.
Neurons are the main cell of the nervous system which is responsible for communication of organs and control of many bodily functions. Neurons transmit electrochemical signals which are known as neurotransmitters and neuromodulators that act as messengers for sensory input and motor output.
Also, the nervous system is composed of two main branches which are the central nervous system and the peripheral nervous system. The central nervous system is composed of the brain and spinal cord whereas the peripheral nervous system is composed of the nerves around the body.
A detritivore is a animal that feeds on dead organic matter. A good example for a detritivore will be option C "Earthworm." A Earthworm feeds on dead organic matter such as dead plants, animals, rotten fruit, etc...
Hope this helps.
Answer:
a) A beaker filled with 1 liter of deionized water? - water will flow into the bag so its volume will increase. The solution is <u>hypotonic</u>
b) A beaker filled with 1 liter of 10% sucrose solution? - water will flow out of the bag so its volume will reduce. The solution is <u>hypertonic</u>
c) A beaker filled with 1 liter of 2% sucrose solution - the volume of water in the bag will stay the same as the two solutions are in equilibrium. The solution is <u>isotonic</u>
Explanation:
Water moves by osmosis through a semi-permeable membrane. Osmosis describes the simple diffusion of water molecules.
Water molecules will move from a high concentration to a low concentration.
- If the bag of 2% sucrose solution is placed in a beaker of deionized water, the concentration of water in the deionized water is in the beaker higher than in the bag (because the water in the bag contains 2% sucrose). Therefore, the water in the beaker will move from a high concentration outside the bag to a lower concentration inside the bag
- If the bag of 2% sucrose solution is placed in a beaker of 10% sucrose solution, the concentration of water in the bag is higher than in the beaker (because there is more sucrose in the beaker). Therefore, the water in the bag will move from a higher concentration inside the bag to a lower concentration outside the bag.
- When the concentration of water is equal, the movment of water molecules reaches an equilibrium and there will be no change in the volume of water in the bag
Answer:
C
Explanation:
Clones are genetically identical. However, traits such as personality are determined by how they are raised. Physically, they can take damage from outside sources, and thus look different.
