Would a human with enough food and water and oxygen in a suit survive a full close orbit around Earth? I would think not because of all the space junk, but thats the only reason I can think of.
Explanation:
except that, their first problem is how to drink the water and eat the food provided while at the same time taking in oxygen...
And the close orbit would either pull them towards earth resulting in a collision
or shoot them out of the orbit at insane speeds
in both case they will die..
as soon as they will enter the earth's atmosphere, they will be burned alive by the heat due to the friction between their body and the air around them when they will be in the process of collision.
even if they avoid all this, they will still either be burn to death or freeze to death on either side of the earth coz the suit is only suitable for a limited amount of time...
A science class is planning an investigation about gravity and objects on Earth. In three to four sentences, explain the steps the class should take to provide data to help them make a conclusion about the effect of gravity on objects of different masses
Gravity is a force that differentially affects objects depending on their masses. It is also a physical property.
What does gravity mean?Gravity is a force capable of pulling objects and/or materials toward each other depending on their masses.
Gravity on the Earth planet is able to maintain minor bodies (e.g., organisms) on its surface.
Gravity is a physical property because it varies depending on the objects that are involved (for example, gravity on Earth and Mars is not equal).

Deforestation is the second leading cause of global warming (climate change) worldwide, and it produces about 24% of global greenhouse gas emissions. Deforestation in the tropical rainforests contributes more carbon dioxide to the atmosphere than the sum of all cars and trucks that drive on the world’s roads.
Why would deforestation this lead to more carbon dioxide?
a
The changed habitats support more animals, like native birds and mammals, that produce more carbon dioxide.
b
The increased amount of timber harvested produces oxygen gas, which encourages the wildlife to generate carbon dioxide.
c
Loss of trees leads to a decrease of the ability of forests to act as carbon sinks to remove carbon dioxide from the atmosphere.
d
Equipment used for clear-cutting produce metric tons of carbon dioxide, which is released into the atmosphere during the process of deforestation
Answer:
C
Explanation:
According to Worldwildlife.org, Forest play a critical role in mitigating climate change because they act as a carbon sink - soaking up carbon dioxide that otherwise be free in the atmosphere and contribute to ongoing changes in climate patterns.

(5 Points)
O A. by conduction
O B. by radiation
O C. By seismic waves
O d. by gravity
the answer is D
"During convection, heat is being transferred between substances in direct contact with each other by electro magnetic waves."
"Using the molten rock to explain the convection in the earth relative to how if affects the weather condition. Here, the rock is in a molten state, rising up from the bottom of the mantle after becoming hotter and less dense from the heat of the earth's core. As the rock loses heat into the earth's crust, it become cooler and more dense,sinking back to the core. These constantly circulating cells of hotter and cooler molten rock help to heat the earth's surface."

Why is carpolestes a prime candidate among plesiadapiforms to be a euprimate ancestor?.
Answer:
Why is Carpolestes a prime candidate among plesiadapiforms to be a Euprimate ancestor? It had an opposable thumb. It had a nail instead of a claw on its first foot digit.
It had an opposable thumb. Its first foot finger had a nail rather than a claw. Plesiadapiforms were previously thought to be extinct members of the order Primates.
What is the Plesiadapiforms?Carpholites has a two-chambered auditory bulla, like Tarsius, which distinguishes it from early EU primates and all other known Plesiadapiforms.Plesiadapiforms are primitive primates, which means they lacked some primate characteristics while exhibiting others. Plesiadapiforms means "nearly adapiform," and refers to Plesiadapiforms that resemble some adapiforms (or adapoids; later-appearing species).Plesiadapiforms were on a much lower evolutionary stage than modern primates, possibly comparable to living tree-shrews despite sharing some skeleton traits. Plesiadapiforms first appear in the fossil record between 65 and 55 million years ago, though many had become extinct by the Eocene. They were possibly the first mammals to have finger nails instead of claws.To learn more about Plesiadapiforms, refer to:
