Answer:
A. Water
Explanation:
Sunlight is absorbed from above through the leaves
Carbon dioxide is absorbed from the air by the leaves
Oxygen is a byproduct of photosynthesis and is released by the plant from the leaves back into the environment.
Answer:
If twins are a boy and a girl, clearly they are fraternal twins, as they do not have the same DNA. A boy has XY chromosomes and a girl has XX chromosomes. Girl-boy twins occur when one X egg is fertilized with an X sperm, and a Y sperm fertilizes the other X egg.
Explanation:
The complementary strand to the original DNA segment of GCTAA is; CGATTA
The rate of a chemical reaction would also increase if you increased the temperature, this is because the thermal energy would change into kinetic energy and the frequency of collisions would increase, increasing the rate.
The molecule of water is different from the molecules of oxygen and hydrogen in the following ways:
1. Combustion: Oxygen supports combustion, hydrogen burns in the air to form water. Water is not combustible. It rather inhibits combustion when poured over burning substances.
2. State of matter: Water is a liquid in room temperature whereas oxygen and hydrogen are gases. The polar nature of water contributes to hydrogen bonding between the hydrogen and oxygen atoms of water.
3. Density: Water is denser than both oxygen and hydrogen. Hydrogen bonding helps pack more molecules of water in less space.
4. Freezing point: Water freezes to ice at 0°C whereas oxygen freezes at -218°C and hydrogen freezes at -259°C.
