The principles of probability can be used toA. decide which organisms are best to use in genetic crosses.

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.

Answers

Answer 1
Answer:

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
Answer 2
Answer:

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.

According to the cladogram which groups of plants would have vascular tissue

Answers

The node in a cladogram represents the formation of a new species. The formation of a new species is termed as a speciation event.The node in  cladogram  indicates the point at which a splitting event,  or formation of a new species occurred.The line between two nodes is called the internode. It represents at least one hypothetical ancestor.A cladogram is a tree shaped diagram that is used to illustrate evolutionary relationships among species by analyzing some similarities or differences in physical features and other kinds of characters in the organisms. 

 The goal of a cladogram is to show relationships and evolutionary descent between species.

As many researchers hypothesize that the old single-celled organism or the origin of the complex-celled organisms came from the endosymbiosis of the mitochrondrion organism and the prokaryotic cell. It has been said that mitochondria was an independent organism which then to have been evovled itself after planting itself inside a prokaryotic cell which aided cellular respiration and production of ATP (Adenosine Triphosphate). This then aided the prokaryotic cell to be more sophisticated and caused another change from having without a true nucleus to a eukaryotic cell with a nucleus and embedded DNA.

What is not the ultimate goal of science is to produce unchanging and absolute answers . Scientists would like to, however, understand patterns, give explanations for natural events, and even make predictions.

In which region of the sun does energy move through circulating currents of gases?

Answers

Answer:

the convective zone of the sun

Explanation:

In the the convective zone of the sun the energy is carried upwards by the rising hot gas and subsequently it cools and descends, that is to say that the energy is transported mainly by means of convection.

In this area, circular current patterns are formed where the hot plasma rises and the cold plasma descends.
It's the Convective Zone

Which of the following best explains why ecosystems need a continual influx of new energy?a. Photosynthesis feeds herbivores, carnivores, and decomposers.
b. As energy is recycled, a small amount is lost as heat.
c. Energy flows through an ecosystem and cannot be recycled.
d. Cellular respiration does not feed back into other processes.

Answers

The option that best explains why ecosystems need a continual influx of new energy is C. energy flows through an ecosystem and cannot be recycled. Given that it cannot be recycled, and it comes and goes, ecosystems need new energy to replace the old one they may have lost over time. Other answers don't really make much sense and don't have a lot to do with energy/
