Answer:
Limited water, food and more distance to the site.
Explanation:
Mark's biggest challenges in trying to get to the Ares IV launch site was limited food and water for the journey and to reach the site on time otherwise his crew can't reach to him. For this purpose Watney begins the 90-sol journey to Schiaparelli, where the MAV for Ares IV has been pre-positioned. The distance is about more than three months and there is no fast moving vehicle which provide quick transportation and he also have limited water and food supply so these are biggest challenges for Mark..
In 1980, a long dormant volcano, Mount St. Helens in Washington state, erupted violently. The eruption wiped out the forested landscape and the wildlife. Months after the initial disturbance, the ash and rock strewn surface began to undergo primary succession.
Answer:
New vegetation and animals came to this place when the environment is suitable.
Explanation:
The ash and rock strewn surface began to undergo primary succession after few month when the soil is cool down because the soil has nutritive medium that helps the vegetation to grow on that land. In the primary succession, the new vegetation grows which is well suited to that environmental condition and uses the nutrients present in that soil for its growth and development. Many new organisms also came to this new landscape when the environment is suitable.

What is evolution? How can evolution be scientific when no one was there to see it happen?
Answer:
Evolution is looking back and using scientific inference to make a timeline on adaptation of a species over time.

Which structures in the cell are protiens assembled in?
The molecules of DNA are
__
so that each cell gets the same directions.
Answer:
Nucleotides
Explanation:
DNA structure
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code
There is higher abundance of lighter elements in the universe than heavier elements.
which sourfe of evidence supports that statement
Cosmic Microwave Background Expanding Universe Universe Composition
Answer:
Due to its formation in the supernova nucleosynthesis.
Explanation:
The higher abundance of lighter elements in the universe than heavier elements occurs due to its formation in the supernova nucleosynthesis. The lighter elements such as hydrogen and helium are present in abundant amount and formed in supernova nucleosynthesis as compared to other heavier elements which are formed through other events. The lighter elements occupy less volume and space as compared to heavier elements which is also a reason for their abundance.
