First move the x from the right side to the left by subtracting. 3x-6+2x-x=-2. combine like terms. 4x-6=-2. add six to both sides. 4x=4. divide 4 on both sides. x=1. hope this helped!
The answers are; A & B
Intuitively as it sounds, cyclic change is the change that recurs over a particular period of time. Seasons recur every year in specific regions on earth. In addition, receeding and expanding of ice caps also occur based on seasons. These two are examples of cyclic changes.
D. DD = 0.0225; Dd = 0.1275; dd = 0.7225
The value of Dd is different in question.
<u>Explanation:</u>
Given -
Dark colored = DD, Dd
light colored = dd
Frequency of allele D = 0.15
Frequency of allele d = 0.85
Hardy-Weinberg equilibrium is applied.
DD = 0.15 X 0.15 = 0.0225
Dd = 0.15 X 0.85 = 0.1275
dd = 0.85 X 0.85 = 0.7225
Therefore, DD = 0.0225; Dd = 0.1275; dd = 0.7225
<span>Protists can be unicellular, colonial or multicellular. Each type of protist has its own phylums or divisions. Protozoans are animal-like. Bacteria and other one-celled organisms are typical prey for a protozoa. Some examples of a protozoa are mosquitoes and amoeba. Algae are photosynthetic and are grouped into divisions depending on pigment similarities. A few examples of algae are sea lettuce and kelp. Fungus-like protists are often brightly colored and get their nutrition by absorbing nutrients from their environment.</span>
