Answer:
Gene mutations provide new alleles, making these mutations the ultimate source of variation. A gene mutation is an alteration in the DNA nucleotide sequence, producing an alternate sequence, termed an allele. Mutations occur at random, and can be beneficial, neutral, or harmful.

2. Tania went outside and made two observations of the Moon that were several days apart. Her
observations are shown in the diagram above. The light part of the Moon appeared to get larger over
time. Why did this happen?
The reason why the light part of the moon appeared to get larger over time is because between the first observation and the second observation, the moon moved so that Tania was able to see not of the half that faces the sun.
It should be noted that from the observation that Tania made, the light part of the moon appeared to get larger over time.
The reason for the above want due to rotation but rather because the moon moved so she was able to see not of the half that faces the sun.

Two systems in the same organism
Answer:
a
Explanation:
Cells are the functional units of life, this means that all living organisms are made up of cells. In multicellular organisms, cells are organized into complex structures such as tissues, organs and systems. A tissue is made up of similar cells which have the similar function. An organ is made up of several tissues while a system is made up of related organs. Example of a tissue is blood which is made up of similar cells such as red blood cells and white blood cells.
A: Two cells in the same tissue.

Bird guides once listed the myrtle warbler and Audubon's warbler as distinct species because of differences in color patterns of the feathers and size of the beak. Recently these birds have been reclassified as eastern and western forms of a single species, the yellow-rumped warbler, based on the observation that the two forms interbreed often in nature and the offspring have good survival and reproduction. The earlier classification into two species was using a species concept; the reclassification is using the species concept. _________
Answer:
morphological; biological
Explanation:
The morphological species concept highlights the importance of physical traits to delimit species. This concept is useful for classifying asexually-reproducing organisms and where lack information on interbreeding (for example, to classify fossils). On the other hand, the biological species concept states that one species represent a group of organisms that can interbreed (or potentially can interbreed) in order to produce fertile offspring. The biological species concept is nowadays the most widely accepted concept to define species.

Which scenario MOST LIKELY represents genetic drift and why?
A. Scenario 1, because chance events led to a decrease in the number of dark beetles.
B. Scenario 2, because chance events led to a decrease in the number of light beetles.
C. Scenario 1, because the light beetles are most fit for the environment.
D. Scenario 2, because the dark beetles are most fit for the environment.
Answer:
A
Explanation:
The hurricane was by chance and genetic drift is about chance
Scenario 1, because chance events led to a decrease in the number of dark beetles. The correct option is A.
What is genetic drift?Genetic drift is a random process that can result in changes in allele frequency in a population over time.
In Scenario 1, random events reduced the number of dark beetles, implying that the frequency of the dark allele in the population decreased.
Natural selection or other factors that would have favored light beetles over dark beetles did not cause this decrease in frequency.
The dark beetles were affected more than the light beetles due to chance events such as random mortality or reproduction.
This is a classic example of genetic drift, in which random events cause changes in allele frequencies over time in a population.
Thus, the correct option is A.

What are the functions of large intestine?The large intestine absorbs water and changes the waste from liquid into stool. Peristalsis helps move the stool into your rectum. Rectum. The lower end of your large intestine, the rectum, stores stool until it pushes stool out of your anus during a bowel movement.
The large intestine has 3 primary functions: absorbing water and electrolytes, producing and absorbing vitamins, and forming and propelling feces toward the rectum for elimination.
The purpose of the large intestine is to absorb water and salts from the material that has not been digested as food, and get rid of any waste products left over.
