Explanation:

Rigel, also known as Beta Orionis, is the star with the greatest luminosity. Therefore option D is correct.

It is a blue supergiant and one of the brightest stars in the night sky. Luminosity refers to the total amount of energy radiated by a star per unit of time.

Rigel's immense luminosity is a result of its massive size and high surface temperature. It is located in the constellation Orion and is approximately 860 light-years away from Earth.

Rigel's brightness and luminosity make it a prominent and significant celestial object, visible even to the eye, and it plays a vital role in the constellation's distinctive appearance.

Therefore option D is correct.

Explanation:

The structure of DNA can be compared to a ladder. It has an alternating chemical phosphate and sugar backbone, making the 'sides' of the ladder. ... These bases make up the 'rungs' of the ladder, and are attached to the backbone where the deoxyribose (sugar) molecules are located.

Answer:B

Explanation:

Codominant is when neither allele is recessive so they are both expressed in the phenotype

A cow having the codominant alleles for both white and black fur will appear to have fur with areas of both black and white fur. This is an example of co-dominance where both alleles are expressed in the different parts of the animal. So option B is correct.

In codominance, two different versions of a gene are expressed separately and they are expressed equally in different parts of the organism. As a result, the traits of both alleles are expressed simultaneously. The term co-dominant means that both alleles are dominant and one allele does not mask the expression of the other.

Co-dominance can easily be spotted in plants and animals. Codominance is observed in some traits that are less visible like blood type. The A and B alleles are codominant and they can be expressed simultaneously.

Answer:

1. The Los Angeles flood of 1938 was one of the largest floods in the history of Los Angeles, Orange, and Riverside Counties in southern California.

2. The flood was caused by two Pacific storms that swept across the Los Angeles Basin in February-March 1938 and generated almost one year's worth of precipitation in just a few days.

3. The Los Angeles, San Gabriel, and Santa Ana Rivers burst their banks, inundating much of the coastal plain, the San Fernando and San Gabriel Valleys, and the Inland Empire.

4. Flood control structures spared parts of Los Angeles County from destruction, while Orange and Riverside Counties experienced more damage.

5. It caused $78 million of damage ($1.42 billion in 2019 dollars),[2] making it one of the costliest natural disasters in Los Angeles' history.[3] In response to the floods, the U.S. Army Corps of Engineers and other agencies began to channelize local streams in concrete, and built many new flood control dams and debris basins

C) phenotypic plasticity

Explanation:

Organisms might adjust their morphology and physiology to a better performance in environmental heterogeneity.

Generalists species might present a higher magnitude of phenotypic plasticity than specialist species.

These bacteria are notoriously adaptable and might be found in many different environments (terrestrial and/or aquatics) where there is no oxygen due to aerobic decomposition of the organic matter.  

They can be found in anoxic sulfuric environments. In the soil, in estuaries mud, in freshwater, in sewage systems, salty waters, thermal water, sulfur deposits, in oil and gas wells, and even in animals and insects intestine.

Answer:

You need to compare the location of bands for X and X's child. X is the mother, so the child will have half of all its bands from its mother, and the other half must be from the father. Some bands that X and X's child have in common are at around 185bp and 130bp (it is difficult for me to determine the exact position). Then look at the bands which X and X's child do not have in common. Those bands must have come from the father. So now you compare the remaining bands to all the bands of Megabucks and see if they match up. You can see a band at around 60bp that the child has. The mother did not have this band, so it must have come from the father. Megabucks does not have this band, so he is not X's father.

Explanation:

I hope this has helped you a little. The main thing to know is that a child's bands come from their mother and father, so if half the bands match up to the mum, the other half have to match up to some of the father's bands. But a child will never have the same set of bands as one of their parents - it will be a mix of both parents' bands.
