When talking about evolution, a good example is bacterial resistance to antibiotics.
We start with a bacteria colony, and in contact with antibiotics, most of them die.
Some of them in the colony do not die and took that antibiotic to create a mutation of its DNA to be resistance to that.
They evolved survive that antibiotic.
Answer:
In C3 photosynthesis, the reactions that require ATP take place in
B) the Calvin cycle alone.
Explanation:
In C3 PLANTS PHOTOSYNTHESIS OCCUR IN TWO STEPS-
1. LIGHT stage , WHICH TAKES PLACE IN LIGHT. In this stage water is split and ATP is released.
2. DARK stage, which takes place in dark. This the stage where calvin cycle takes place which require ATP, i.e energy. In this process sugar is produced with help of carbon dioxide. In this carbon dioxide is accepted by 5- carbon molecule ribulose-1, 5-biphosphate, which result into two molecules of 3- phosphoglycerate. this three carbon compound. hence is called as C3 pathway. hence C3 plants.

The F2 generation phenotypes for each cross are shown in Table 1. (See attachment) Which of the following is the mean number per cross of F2 generation offspring that are the result of crossing over?
Answer:
B, 2.2
Explanation:
The parental genotypes are long and black vs short and white. Therefore the phenotypes that result from crossing over are long and white, and short and black. (middle two rows of the table). If we add up the total number of offspring with these genotypes we get 6 long whites, and 5 short blacks.
The total is 11 from 5 crosses, so the mean is 11/5 = 2.2
