Answer:

The correct answer is scientific knowledge can be revised with time.

Explanation:

The kingdom classification system is a system of classifying organism based on their similar and distinctive characters.

Linnaeus divided the nature into three kingdoms-animal, plants and mineral kingdom but this kingdom showed no relationship among them.

This classification system has kept on changing with the advancement in science and addition of new information to the science like Ernst Haeckel in 1866 proposed third kingdom of life called Protista which with the development in microscopy got changed again by Copeland as he proposed a fourth kingdom system called Monera. In 1969, Robert Whittaker proposed a fifth kingdom called Fungi which again with the advancement in molecular studies got changed by Carl Woese in 1970 as he divided the prokaryotes in Eubacteria and Archaeobacteria.  

This shows that scientific knowledge expands and  changes with time with the advancement in technology and ideas which lead to the changes in the existing information so has to be revised.

Thus, scientific knowledge can be revised with time is the correct answer.

what probability do we have of obtaining a purple flower (Rr), when we combine two blue flowers (rr) in an incomplete Dominance
34kurt

Answer: none

Explanation:

If we have that the color characteristic is regulated by the dominant gene R, by crossing two blue flowers with the recessive gene r, no violet flower will be obtained, since the rule of incomplete dominance describes that phenotypes can be obtained intermediates of homozygous parents, however in the case, we only have 2 parents with the same recessive conditions, which do not contribute to generate the violet, to produce one of the parents should have a gene that expresses the color red

Answer:

Explanation:

The third-quarter moon, also known as the last quarter moon, rises around midnight and sets around noon. Crescent Waning From our vantage point, the Moon is nearly back to the point in its orbit where its dayside directly faces the Sun, and all we see is a thin curve

When you look at a waxing crescent moon, you see a thin fraction of the moon's illuminated side and a larger fraction of the moon's night side, which is submerged in the moon's own shadow. Earthshine on a waxing crescent moon

The Decline The Gibbous phase occurs when the illuminated portion of the Moon decreases from 99.9 percent to 50.1 percent. It begins shortly after the Full Moon and continues until the Third Quarter Moon. Waning refers to the fact that it is shrinking and becoming smaller, whereas gibbous refers to the oval-to-round shape.

Hope this helps you!
