3241004551 [841]

Answer:

Dr. Alexander is a scientist who studies a certain type of fly. In his studies, he came across information that says that the fly doesn't need any calcium in its diet. This question interests him because he doesn't think it is true. He decides to create an experiment that will test whether this question is true. His hypothesis is that a fly will not live without calcium in its diet.

Dr. Alexander believes that flies must have calcium in their diet. In one of Dr. Alexander’s experiments, he feeds one hundred flies a normal diet with calcium. Then he feeds one hundred more flies a diet without calcium. Over seven days he records the following data:

Fed Calcium Not Fed Calcium

Flies alive before test 100 100

Flies alive after test 92 10

Based off the data above what would be a valid conclusion Dr. Alexander could make?

Calcium is an essential part of a fly's diet.

The experiment did not provide definite results.

Calcium is a nonessential part of a fly’s diet.

mamaluj [8]

Answer:

Lamarck:

The inheritable traits of species may change over time.

Malthus:

In every species in nature, some individuals survive while may others die.

Hutton, Lyell:

The environment of organisms may change over time.

Explanation:

Darwin's revolutionary ideas were influenced by a number of scientists and thinkers of the time:

Jean Baptiste Lamarck:

A botanist and zoologist, Lamarck, for, the first time, proposed the idea of evolutionary changes or adaptations in organisms in response to changes in the environment. He introduced the concept of inheritance of acquired characters.

Thomas Malthus:

Thomas Malthus was not a biologist, but an economist who proposed the ideas that at the rate of the current population growth, human population would eventually suffer from famine and starvation.This would lead to the deaths of the weakest of the population. This idea inspired Darwin to formulate the idea of "the survival of the fittest".

Charles Lyell and James Hutton:

Charles Lyell and James Hutton were famous geologists who greatly influenced Darwin with their theories about the beginning and evolution of the Earth. Charles Lyell proposed that the present state of the Earth was a result of small, gradual changes. James Hutton theorized that the processes that too place at the beginning of the Earth were still in progress.

Lyell and Hutton's work paved the way for the formulation of the theory of natural selection.

Tobacco mosaic virus has RNA rather than DNA as its genetic material. In a hypothetical situation where RNA from a tobacco mosai
jolli1 [7]

Answer:

The correct answer is A. Tobacco mosaic virus

Explanation:

Virus can have DNA and RNA as its genetic material. Tobacco mosaic virus has RNA as its genetic material. Protein is not a genetic material because it is a product coded by genetic material.  

So a hybrid can be made only when the genetic material of two different organisms is mixed not two different biomolecules. Therefore when RNA from the tobacco mosaic virus is mixed with the protein from a DNA virus the result would be a tobacco mosaic virus only.
