The DNA molecule is a double helix, shaped like a twisted ladder.
Answer:
pH meter and pH paper.
Explanation:
There are a few other ways that are commonly used, including titration, but most are tedious and require detailed hands-on work. A pH meter is normally assisted by the use of a computer or a digital user interface. The use of pH paper can be likened to the use of a Galileo thermometer.
Answer:
1. Meiosis 1.
2. Meiosis 2.
3. End.
4A. The chromosome theory of inheritance states that chromosomes are the main carriers of the genetic factors responsible for inheritance.
B. Body cells have two sets of chromosomes while sex cells have one set. Therefore, when two sex cells meet, they form an embryo with two copies of each chromosomes thereby producing a body cell with the exact number of chromosomes. In essence, meiosis maintains the right number of chromosomes of body cells by creating half the number of chromosomes of sex cells.
C. Meiosis.
Explanation:
<span>Evaporation and transpiration.

The evaporation process uses the sun radiation or sun’s
thermal energy for vaporization of a water from the land or soil to be water
vapor then in the air. Transpiration on the other hand is the same with evaporation
that involves water molecules to be vaporized into the air but it is located in
the stoma of the plants. It is like evaporation within plants. This is actually
to have homeostasis in plants and still part of the water cycle.
The grass would probably not live!
