Answer:
A hypothesis is a tentative answer to a scientific question. A testable hypothesis is a hypothesis that can be proved or disproved as a result of testing, data collection, or experience. Only testable hypotheses can be used to conceive and perform an experiment using the scientific method
Explanation:
<span>A mutually dependent relationship exists between chloroplast and mitochondria in the plant cell. Photosynthesis, which occur in the chloroplasts,generates the sugar and oxygen gas that are used in mitochondria for cellular respiration. It generates carbon-dioxide which in turn is used as a carbon source for the synthesis of sugars during photosynthesis.</span>
<span>Having
constipation while also having hemorrhoids is a nightmare. You already face
inability passing out poop, yet you still have to brace for intense pain as you
strain to get it out. It is close enough to death by a thousand strains. In
those cases, doctors prescribe stool softeners so the patient can pass out
stools faster and experience lesser pain. Doctors have lots of laxatives to
choose from. The most common one prescribed for hemorrhoids-related
constipation is lactulose. Lactulose is composed of undigestible sugars that
swell once it travels down the large intestine, adding bulk to the stool. It is
preferred because it does not alter function of the intestines.</span>
There are several evidences of evolution, some that we have greater knowledge and others we don't, but in this question all alternatives contain evidence of evolution, to understand better we need to know that.......
<h3>Fossil Evidence</h3>
Fossils are remains or traces of preserved organisms that are more than 10,000 years old and provide important information about life in past times and what the environment was like at a given time.
- Bones
- Teeth mark
- Footprints
- and petrified feces are examples of fossils.
<h3> Comparative embryology and Homologous structures</h3>
Some species have anatomical characteristics that are very similar to those present in individuals of other species. Although these structures often do not have the same function, it is possible to infer that, at some point, these species had a common ancestor.
<h3>Biochemistry and Metabolism</h3>
The analysis of cells and the biochemistry of organisms have revealed that there is much similarity between all living beings. This fact suggests that, at some point in evolutionary history, we had a common ancestor.
It can be seen, therefore, that the theory of evolution is supported by several pillars and every day it is more evident that living beings undergo changes over time.
With this information, we conclude that <u>all alternatives are evidence of evolution.</u>

Population decreases by 15.
Birth rate means more population (positive), death rate means less population (negative), immigration means more (positive), and emigration means less (negative). So, just add and subtract the appropriate numbers:
Negative 15 people means that the population decreases by 15.
