A scientist is trying to determine which clade an organism best fits into based on its characteristics. He has determined that t
he organism must belong to either the clade of bacteria or fungi. Which of the following characteristics would best indicate that the organism is a bacterium? A.
The organism is heterotrophic and cannot make its own food.
B.
The organism's cells each contain a membrane-bound nucleus.
C.
The organism can move around its environment using a flagellum.
D.
The organism is made up of more than one cell.
When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral.
We will use the Hardy-Weinberg equation ; p2 + 2pq + q2 = 1 q2 represent the frequency of the recessive trait in the population which is 400/10000 = 0.04. Then find frequency of the recessive allele. q = 0.2. While we understand that p+q =1 ; p = 1-q ; p = 1-0.2 =0.8. 2pq represents the frequency of heterozygous trait in the population. Therefore 2*0.8*0.2 =0.32 0.32*10000 = 3200
