Answer:
<u>Humans need to interact with the environment to obtain our food, water, fuel, medicines, building materials and many other things. Advances in science and technology have helped us to exploit the environment for our benefit, but we have also introduced pollution and caused environmental damage.

Explanation:
1. change
The natural selection is a process that occurs as a direct consequence of the living conditions in the environment. When the environment starts to change though, the organisms that live in it face a big challenge. They either have to change, adapt to the new conditions, and thus survive, or if they are not able to do so, to die out. This is the biggest evolutionary pressure for the organisms, and while some come out as winners from it, many others die out .
2. variation
In order for the process of natural selection to occur, the population needs to have some genetic variation. The environment is the ultimate push factor, but if the population doesn't have genetic variation in it, than the species will die out. The genetic variation is very important as in that way the individuals choose who will they mate with, in accordance with their traits, so that only the advantageous traits can be passed on to the next generation, so that it can be more competitive in the environment.
3. traits
The natural selection is a very simple process. The individuals of a population, when choosing a mate, look for the individuals that exhibit traits that are advantageous for survival. Mating with individuals with traits that are advantageous guarantees that the offspring will inherit those traits, thus it will have higher chances to survive. The individuals that do not have advantageous traits though will be avoided as mating partners, and that would rapidly lead to their decline and elimination from the gene pool, as they will not have any offspring to continue their line.
The answer is sediment.
There are three types of rocks: sedimentary, igneous, and metamorphic. The only one that would make sense here is sedimentary because the question states a rock that is made from layers is formed which describes a sedimentary rock.
Answer: False
Explanation:
Range of measurement can be defined as the amount of movement around a specific body part or joint.
It is generally used during the time of evaluation of treatment or during a course of treatment.
This is a type of impairment. Other impairment which can also be used are flexibility, strength, gait or balance.
<span>Jennifer's physician suspects she may have an ulcer in the _duodenum_, which is the first section of her small intestine.
The small intestine connects directly to the stomach via the pyloric sphincter. A peptic ulcer involves the spilling of very acidic stomach juice into the duodenum, which is the closest portion of the small intestine to the stomach. This can present as epigastric pain (in the upper center abdomen, just below the xiphoid process, or lower portion of the sternum). Usually it is brought on by ingesting acidic or spicy liquids, alcohol, or after going several hours without eating. Those ingestions can ramp up gastric acid production, and having nothing in the stomach allows pure acid to spill into the duodenum, which irritates an already eroded mucosal epithelium. Eating non-acidic, non-spicy foods like bread or milk helps to alleviate the pain by soaking up the acid in the stomach (bread) or neutralizing some of it (milk). But an empty stomach poses the largest risk of irritation. Also the epigastric region hones the pain in on the duodenum, since it crosses midline from the left upper abdomen (stomach) towards the right side as it continues on. If it were acutely painful in only the left upper quadrant (LUQ) of the abdomen, it would almost assuredly be gastritis or a gastric ulcer (gastro- meaning stomach).</span>
