The National Aeronautics and Space Administration (NASA) has designed many robots to help astronauts explore space. Some robots drive around like cars, some are just large arms, and some look like humans. All of these robots can accomplish tasks in space that are too difficult or dangerous for astronauts to do alone.
2
The most famous NASA robots are called the Mars rovers. According to NASA, the wheeled rovers are part of the Mars Exploration Program, “a long-term effort of robotic exploration of the red planet.” The newest rover, Curiosity, landed on Mars in August 2012. The size of a small car, Curiosity carries advanced equipment to analyze the soil and air on Mars. Curiosity has made many exciting discoveries about the planet's environment. Most importantly, it discovered that Mars contains the right ingredients to support life, including carbon, oxygen, and water. Curiosity has also found that astronauts on Mars would be exposed to dangerous levels of radiation. This discovery will help NASA protect its astronauts when they one day travel to Mars.

NASA is also building other robots. For example, the Robonaut2 looks like the upper half of a human. The human hand is a very complex and useful tool. It might seem easy for a person to press a button, grasp and lift an object, or turn a knob, but these tasks are very hard for a robot. However, a robot that could perform these tasks would be very useful to astronauts. The Robonaut2 is now being tested at the International Space Station (ISS). Eventually, NASA wants to add legs or wheels to the Robonaut2, which would allow it to move around outside the ISS.
4
Another robot on the ISS is a massive arm called Canadarm2. It can do repair work and transport objects too big for humans to move. Canadarm2 has even caught the Hubble telescope to allow astronauts to repair it. As technology develops, NASA will increasingly rely on robots. They will guide astronauts in new places, give them medical care, and do dangerous work for them. With their special equipment and considerable strength, robots can help humans explore new worlds.

Please write 1–2 sentences relating the water cycle and wind to temperature and precipitation.
Quickly please
Answer:
Some examples of precipitation include rain, snow and hail. Precipitation is a part of the water cycle. Once the rain leaves the clouds, it forms a stream/ river to get to a lake or ocean. From there transpiration takes place to make those droplets form clouds. The sun mover the clouds, and we get back to transpiration.

What information do genes determine when building proteins?
choose all that apply:
the amino acids that are used.
the order of the amino acids.
the location where the protein is built.
the total number of amino acids.
Answer:
Most genes contain the information needed to make functional molecules called proteins. (A few genes produce regulatory molecules that help the cell assemble proteins.) The journey from gene to protein is complex and tightly controlled within each cell. It consists of two major steps: transcription and translation.

Answer:
A
Explanation:
Plants rely on energy from sun rays to feed itself. Plant's leaves spread out and collect energy from the sun for the plant (A plant's leaves and roots are kind of like it's mouth, leaves for sun rays ; roots for water) So, to maximize the amount of energy the plant receives, the plant bends the leaves towards the sun.

so long as that stands for eukaryotic
fungi is eukaryotic
other 2 are multicellular, and therefore eukaryotic
if u don't like the first explanation, the second one is process of elimination
archaebacteria is a kingdom, so it can't be that, same with plantae.
fungi isn't a bacteria so it can't be that either

Severe weather can occur anywhere, but not every area experiences the same severe weather. Hurricanes are a type of severe weather that only occurs in certain places. In the space below, explain why hurricanes form in tropical latitudes and not in other places.
Explanation:
The reason that hurricanes form around the tropics and not at the equator is that there needs to be Coriolis effect. Coriolis effect is what cause the winds to deflect to the right in the Northern Hemisphere and the left in the Southern Hemisphere.

“Coronavirus Is Mutating”, what could be the reason for it? (Research) and tell your answer in your own simple words
Answer:
Explanation:
Coronavirus is mutating because as more people are getting the virus, that gives that virus a change to mutate and form a different strand. When a virus hijacks a person cells, it causes that cell to start producing the DNA of the virus, but because human cells where not made to produce the DNA of a virus, mistakes happen, thus slightly changing the DNA of the virus which can then cause a new strand of the virus to appear.

c
Less nitrogen will be absorbed from the atmosphere over these areas.
d
Cattle will get fewer nutrients grazing on nonnative grasses than on rain forest plants.
Answer:
It should be
A. The biodiversity of these areas will decrease.
The biodiversity of these areas will decrease describes the MOST LIKELY impact of the replacement of rain forest plants with nonnative grasses. thus option A is correct.
What is biodiversity ?
Biodiversity can be defined as the total number of living organisms present in a particular area dependent upon different factors like habitat, competition among species, resources, and climatic conditions.
There are three types of biodiversity such as genetic, species, and ecosystem diversity.
In a specific area the increase in human population makes a problem for the biodiversity with the increase in population and it comes a need to convert natural habitats to land for human consumption and shelter.

The following statements about animal behavior are false: Two animals of the same species will behave differently, as shown in Option A, as there are many similarities in behavior between members of the same species.
What is animal behavior?Animal behavior is a complex and fascinating topic that can shed light on a variety of biological questions, including how animals interact with their environment, how they communicate with each other, and how they adapt to changing conditions. One important aspect of animal behavior is the distinction between instinctive and learned behaviors. Instinctive behaviors are innate, meaning that they are genetically programmed into an animal and do not require any prior learning or experience.
Hence, the following statements about animal behavior are false: Two animals of the same species will behave differently, as shown in Option A.
