Explanation:
Before humans ever ventured into space, we fantasized about visiting—and even living on—other planets. As technology continues to develop, it may one day be possible for humans to call planets other than Earth's home. Space scientists have several possible Earth-like planets and moons insight, but one that is of high interest is Kepler-186f, a planet 500 light-years away. It orbits a star much like the Sun, and it orbits in a habitable zone: it is far enough from the star to allow for the pooling of water (if it is present) on the planet's surface.
Is being in a "habitable zone" enough to say the planet is habitable for human life? What characteristics would an Earth-like planet need to have to support life? What challenges would we face traveling to and colonizing Kepler-186f or other Earth-like planets outside of our solar system? Do you think scientists should spend time looking for Earth-like planets before we have the technology to visit them? Why or why not? PLEASE HELP ME!!! :((
Answer: yes because A habitable zone (HZ) in astronomy is a region of space where conditions are best for life to form as on Earth. Planets in these areas are the most likely to have extraterrestrial life. The habitable zone may also be called the "life zone", "comfort zone", "green belt" or "Goldilocks zone".

Why do animal cells not need the same structures vacuoles, cell walls and chloroplas, that plant cells need?
Answer:
Both animal and plant cells have mitochondria, but only plant cells have chloroplasts. Plants don't get their sugar from eating food, so they need to make sugar from sunlight. ... Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria.

Which property of minerals is the least reliable for identifying minerals?
hardness
luster
streak
color
Answer:
color.
Explanation:
Although color is the most obvious of mineral properties it is the least reliable for identification purposes. This is because the color of a mineral can be altered by slight chemical impurities within its crystal structure.
The color of a mineral is the least reliable for identifying minerals. Therefore, option D is correct.
What are the properties of minerals?A mineral species is identified by two distinct characteristics: its crystal structure and chemical composition. Each mineral has a unique three-dimensional arrangement of the atoms that make up its structure. Its physical characteristics, including cleavage and hardness, are impacted by its regular geometry.
Because they are composed of many elements, minerals have unique qualities. Iron, calcium, magnesium, silicon, carbon, phosphorus, oxygen, and many more naturally occurring elements can be found in minerals. Based on how many electrons each of these native elements have, they have various qualities.
The color of a mineral is the least reliable for identifying minerals. Therefore, option D is correct.

Which of the following describes a polar orbit?
Answer:
Explanation:
A polar orbit is one in which a satellite passes above or nearly above both poles of the body being orbited (usually a planet such as the Earth, but possibly another body such as the Moon or Sun) on each revolution. It therefore has an inclination of (or very close to) 90 degrees to the body's equator.
