NASA is currently working on sending humans to Mars by the 2030s. When astronauts arrive on Mars, NASA intends to already have their food supply there. The food will be sent by an unmanned spacecraft. It will then be stored, unrefrigerated, for five to seven years.
List at least two likely constraints and two likely criteria for this engineering design problem.
Answers
Answer: Two likely constraints are time and money. Two likely criteria for this problem are to make sure that the food doesn't get affected by the radiation and that the food doesn't get old by the time humans get there.
The constraints include costs and time whereas criteria include mutagenic agents (radiation) and food preservation.
What does interplanetary travels mean?The expression 'interplanetary travels' makes reference to the likelihood to send people to other planets in the future.
The interplanetary travels are fully charged with challenges we need to solve, especially associated with the availability of foods.
In conclusion, the constraints include costs and time whereas criteria include mutagenic agents (radiation) and food preservation.

Darwin observed fossils of glyptodonts, which are now extinct. Living armadillos are the only animals remaining on Earth that are similar to glyptodonts. Armadillos live in the same places that glyptodonts lived.
What did Darwin most likely conclude about the two types of animals?
Glyptodonts were better adapted to the environment.
Glyptodonts outcompeted armadillos for food.
Glyptodonts were early relatives of armadillos.
Glyptodonts had the exact same adaptations as armadillos.
Answers
Answer:
3. Glyptodons were early relatives of armadillos.
Explanation:
Darwin would have come to this conclusion because glyptodons over time became armadillos, which you can tell by evolution that they were better evolved to survive than glyptodons. Due to this, they outlived the glyptodons.

Answers
D.)Revolution
Hope I helped
The Earth moves in predicable patterns. This patterns causes the seasons as the Earth moves around the Sun along its elliptical orbit. This movement is referred to revolution.
The correct answer is option D
Earth rotates about its axis about 24 hours. The rotation of the earth about its axis causes day and night.
The earth experiences an equinox between March and September when the sun is over the equator.
Photoperiod is also known as day length. This occurs when the organism most especially, plant organism receive their daily illumination from sun.
A Revolution: Earth revolve around the sun for about 366 days. That is a year.
Earth revolution is in a predictable pattern that causes the different seasons and weathers as the Earth moves around the Sun along its elliptical orbit.
Therefore, The Earth moves in predicable patterns. This patterns causes the seasons as the Earth moves around the Sun along its elliptical orbit. This movement is referred to revolution.

What is the final internal (thermal) energy of the system if the initial energy is 1,500 J?
200 J
800 J
1,300 J
1,700 J
Answers
Answer: The final answer is 1,700 J
Explanation: According to first law of thermodynamics:
=Final energy-initial energy=Change in internal energy
q = heat absorbed or released
w = work done by or on the system
w = work done by the system= {Work done by the system is negative as the final volume is greater than initial volume}
q = +500J {Heat absorbed by the system is positive}
w = work done by the system = -300J
U2- 1500J= + 500J --300J
U2= 1700J
