The exchange of genetic material between organisms living at the same time in the same environment is known as horizontal gene tratransfer. This process, along with gene flow, contributes to genetic diversity and reduces the risk of extinction.
Genetic exchange between organisms living at the same time in the same environment is considered to be Horizontal gene transfer. This concept involves the introduction of genetic material from one organism to another within the same generation. It is different from vertical gene transfer, which is the transmission of genetic information from generation to generation. Horizontal gene transfer allows even distantly related species to exchange genes, impacting their phenotypes. Gene flow is another related concept, which involves the exchange of genetic material between populations, contributing to genetic diversity and reducing the risk of extinction.

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.

Answer;
C. Biomes
Savanna is considered a transitional biome because it is intermediate between two biomes.
Explanation;
Savanna biome is a transitional biome between those dominated by forests and those dominated by grasses. It is characterized by an extensive cover grasses with scattered trees.
Normally savanna biomes are associated with climates having seasonal precipitation accompanied with a seasonal drought.
Answer:
c - biomes
Explanation:
Answer:
All carbohydrates, including sugar, contain the same three elements: carbon, hydrogen and oxygen. Different arrangements of these elements form single units to make different types of carbohydrates.
Carbon and hydrogen
Answer:
The correct answer will be option-C.
Explanation:
Hydrolysis is a type of chemical reaction where a water molecule is utilized or consumed to rupture the chemical bonds. In these reactions, water acts as a nucleophile and separate the larger molecules into its components.
In the given question, the process of cellulolysis or the breakdown of cellulose to smaller polysaccharide like cellodextrins or glucose units is a hydrolytic reaction. This reaction requires an ionic solvent as cellulose molecules bind strongly to each other and cellulolysis Is difficult.
Thus, Option-C is the correct answer.
Answer:
Heart is made of strong cardiac muscle with the closed fist of a man. It position is behind the sternum in between the lungs,nearly2/3rd of the part falling on the left hand side and remaining 1/3rd to the right side of the sternum .It weight nearly 450 grams in grown up males but weight less(about 300grams) in women The number of heart beats minute in an adult is about 72.
