Answer:
Root and shoot
B. predict the traits of the offspring of genetic crosses.
C. determine which species should be used in genetic crosses.
D. determine the actual outcomes of genetic crosses.
Answer:
Option B, predict the traits of the offspring of genetic crosses
Explanation:
Lets see an example -
Suppose there are two adult cats , where female cat has brown (BB)haired and it is a dominant trait while male cat is recessive grey (bb) haired organism.
If a cross is carried out between these two species then through probability it can be derived that how many species will be grey (Bb) haired
Let see the punnet square for the cross-
B B
b Bb Bb
b Bb Bb
Thus out of four offspring’s produced all the offspring’s are grey (Bb) colored. Thus, there is a 100% probability that if a cross is carried out between female cat having brown hair (BB) and a male cat having black hair (bb), the offsprings will have grey (Bb) hair.
In this way probability can help to predict the traits of the offspring of genetic crosses
The laws of probability can be applied to genetics to make predictions about the traits of the offspring that result from genetic crossings. Therefore, the correct option is B.
Probability enables us to calculate the likelihood that specific characteristics will be inherited, based on the known genetic information of the parent organism. Scientists can predict the possible combinations of genetic characteristics in offspring by understanding the principles of heredity and applying probability calculations.
Probability can forecast and infer, but it cannot predict the actual results of genetic crosses because these are affected by various processes, including random segregation during meiosis and genetic recombination.
Therefore, the correct option is B.

The correct answer is phototrophism.
Phototrophism is said to be the growth of a plant toward a source of light.
It is response to the stimulus of light and is seen when a plant bends towards the direction that light is coming from. Response by plants to a stimulus is called tropism. The word or prefix "photo" means or refers to light. Therefore phototropism simply means response to light.
Phototropism can be especially evident in the jungle where the jungle floor gets very little light. If a tall tree falls to the ground, it leaves a gap in the canopy through which sunlight streams to the ground. Many jungle plants growing on the ground will bend towards the gap and rapidly grow towards the source of light.
Answer: PHOTOTROPISM
Explanation:
Answer:
B. viral reverse transcriptase to make a DNA copy that is integrated into the host genome and then host RNA polymerase transcribes it.
Explanation:
RNA retrovirus when enters into its host cell it first use its reverse transcriptase enzyme and converts its RNA genome into the DNA so that viral DNA can be incorporated into the host cell and it can be replicated with the host cell.
One of the famous example of RNA retrovirus is HIV which infect CD4 cells and converts its RNA into cDNA with the help of reverse transcriptase enzyme and then this DNA enters the nucleus of the cell and incorporates into the host genome. Then it use host machinery to be transcribed. So the correct answer is B.
