Due to the overproduction of offspring with only finite resources, species begin to engage in competition for survival. In order to increase their chance of survival, certain species will begin to develop genetic variations that allow them survival advantages.
The correct answers are:
B. Warmer air promotes more evaporation.
D. Humidity refers to the amount of water vapor in the air.
E. Areas with a lot of surface water have higher humidity than drier areas.
The humidity can simply be described as the amount of water vapor in the air. The humidity can vary, and it can be very high in certain place for the whole year, very low at other places for the whole year, or to be changing seasonally.
The areas that have a lot of surface water (the Amazon River Basin) tend to have higher humidity than the places that lack surface water (Sahara Desert). Also, the humidity depends a lot on the temperature of the air. The warmer the air is, the higher the humidity, and vice versa, the colder the air is, the lower the humidity.
<span>The correct answer is Marchantia, or as its full name is Marchantiophyta. They are vascular land plants that also go by the name of liverworts or hepatics and they are quite common and very similar to mosses because they have the same way of reproduction and some types even look like some types of mosses.</span>
During inter-phase of cell division, the genetic material is duplicated to allow for division into 2 identical daughter cells. The tumour suppressor gene checks for errors in the DNA, and if found, apoptosis (cell death) is initiated by p53 protein. The pRb (retinoblastoma) protein stops the progression of the cell cycle form G0 into S phase if the cell division is complete hence stemming unregulated cell division.
