From my speculation it is loss of habitat and global warming
<u>Full question:</u>
Thousands of years ago, giraffes with short necks were common within giraffe populations. Nearly all giraffe populations today have long necks. This difference could be due to
giraffes stretching their necks to keep their heads out of reach of predators
giraffes stretching their necks so they could reach food higher in the trees
a mutation in genetic material controlling neck size occurring in some skin cells of a giraffe
a mutation in genetic material controlling neck size occurring in the reproductive cells of a giraffe
<u>Answer:</u>
This difference could be due to:a mutation in genetic material controlling neck size occurring in the reproductive cells of a giraffe
<u>Explanation:</u>
The primary short-necked forms contained large, mutable populations. Following the selection pressure of desiccations and leaf deficiencies, those changes with longer necks and forelegs sustained and repeated preferentially. In this procedure, throughout generations, these large mammals have occurred, being acclimated to their unique environment .
Lamarckian theory illustrated giraffe neck metamorphosis by showing that consistent stretching gradually extended their necks, and that they then moved on these propitious longer necks to their offspring. Environment and other variations created the extirpation of the eurasian giraffids, but various African species endured.
Explanation:
The uneven warming of the earth surface causes land and sea breeze over the land and water.
Water has a very high specific capacity and it takes more heat to cause a fractional increase in its temperature. During day, the air around water is cold and dense and under high pressure.
The land adjacent to the water, is a better conduct with a low specific heat capacity. When warming of the earth starts by the sun, the air on land heated by heat radiated from the surface. Air on land is warm, less dense and light.
This forces the air on land to move seaward and the cold air from the sea to move land ward and a sea breeze is set up.
At night the reverse is the case. The land loses heat very fast and the air around it is cold and dense. The water body does not lose heat so fast and the air around is warm and lighter. Air from the land replaces that on the surface of water and a land breeze is set up

I have never heard of the four phases of research, but I know that the scientific method can be summarized in four steps.
1. Observe something in nature.
2. Make a hypothesis (prediction) based on that observation.
3. Design and undergo and experiment to test the validity of your hypothesis.
4. Draw a conclusion about your hypothesis based on the results of your experiment.
Answer:
Plants use the process of photosynthesis to remove oxygen from the air.
Explanation:
Photosynthesis process:
Carbon dioxide combines with water to produce glucose and oxygen by the help of chlorophyll and light
