Which statement correctly summarizes the structure of living organisms? A. All living organisms are composed of a single cell. B
lesantik [10]

Answer: Option B) All living organisms are composed of multiple cells.

Explanation:

According to the CELL THEORY

- the cell is the structural and functional unit of life

- all living organisms are made of cells

- all cells come from previously existing cells

- there is no life apart from the life of cells

- all living things are either single cells (unicellular) or group of cells (multicellular).

Thus, the correct statement is that all living organisms are composed of multiple cells

The frequency of purple pollen cones is 0.34 in a population of Virginia pine (Pinus virginiana). In the same population, the fr
lubasha [3.4K]

Answer: P(p and f) = 0.23

Explanation: The frequency of a specific trait is also the probability of that trait appearing in that population. So:

Probability of purple pollen cones: P(p) = 0.34

Probability of four needles per fascicle: P(f) = 0.67

Using multiplication rule:

P(p and f) = P(p)*P(f)

P(p and f) = 0.34*0.67

P(p and f) = 0.23

The probability of having both purple and four needles is 0.23

If the mother is heterozygous and the father is heterozygous what is the genotype probabilities?
PSYCHO15rus [73]
So we’ll just use “R” and “r” for this example. If the mother AND father are heterozygous, then both of their genotypes are “Rr” if you work out the lumber square or use the foil method, the box would look like this: RR on top left, Rr on top right, Rr on bottom left, and rr on bottom right. So the genetic probabilities, using four as the sum would be 1:2:1
