A meteor crashed into earth carrying a strange alien gass. The gas wasn't poisonous, but it did remove all the cholorplasts from EVERY plant cell on earth.
(How would earth be different?)
(How would this change life for humans?)
What is natural gas and how does natural gas work?
Answer:
A molecule of natural gas is made up of carbon and hydrogen. When the hydrogen is segregated from the carbon and filled into a fuel cell, it fuses with oxygen to produce water, electricity, and heat. The carbon is released as carbon dioxide in smaller quantities than from gas turbines
Explanation:
Koalas are marsupials that are found in eastern Australia. Although their ancestors lived mostly on the ground,
modern koalas spend most of their time in eucalyptus trees. This is possible because their hands and feet have
strong claws and opposable digits.
What other adaptation could have helped koalas as they evolved from land dwellers to tree dwellers?
Answer:
Fur color that closely matches the eucalyptus bark color
Explanation:
In terms of evolving from land dwellers to tree dwellers, the number of offspring does not matter. Although the ability to run faster is a good evolution for escaping predators, it does not help the koalas evolve to be better tree dwellers (how would you run using only the trees?). Communicating with their peers would be convenient for survival, but it does not help koalas become better tree dwellers. What does help koalas survive better by traveling through the trees is camouflaging with the bark of the tree to hide from predators.

Which is more appropriate?
a phytoplankton - fish - shark - whale
b shark - fish – krill – phytoplankton
c phytoplankton - seaweed - fish – whale
d phytoplankton - krill – fish –
Answer:
The answer is B.
Explanation:
If you are looking for biggest to smallest this is the answer. Or, who eats who.
Answer:
A
Explanation:
Phytoplankton and algae form the bases of aquatic food webs. They are eaten by primary consumers like zooplankton, small fish, and crustaceans. Then fish get eaten by large predators, such as sharks, tuna, squid and octopus as well as marine mammals like seals and some whales form the top of the food chain. Next a shark is eaten by a whale. These whales have been known to attack and eat everything from small fish and turtles to squid, seals, sea lions, and even large whales. Killer whales also hunt, attack, and eat sharks. That is a food chain from smallest to biggest :)

In mRNA, the protein encoding sequence is found in:
a) Introns
b) Exons
c) Poly A
d) None of these choices
During the splicing process, introns are eliminated, leaving just exons in the final mRNA, which are then employed to control the production of proteins, hence option B is correct.
What are exons?The part of the mRNA that is actually translated into protein is the coding region, often known as the coding sequence or CDS.
The 5' UTR and 3' UTR, untranslated portions of the mRNA, are also present. A procedure known as alternative splicing allows exons to be spliced together in various configurations.
These exons and introns are a part of the earliest messenger RNA products produced during gene transcription. Exons can either be coding or non-coding, depending on whether they include instructions for building a protein.
Therefore, a section of the genome known as an exon is found inside an mRNA molecule, hence option B is correct.

Type the correct answer in the box. Spell all words correctly. What is the name of this ocean? The blank Ocean has the deepest depression in the world, called the Mariana Trench.
Answer:
Pacific Ocean
Explanation:
thats where it is
The Pacific Ocean has the deepest depression in the world, called the Mariana Trench. The Mariana Trench is the deepest part of the world's oceans, located in the western Pacific Ocean.
Explain The Pacific Ocean.The Pacific Ocean is the largest and deepest ocean in the world, covering an area of about 63.8 million square miles and accounting for more than one-third of the Earth's total surface area. It is located between Asia and Australia to the west, and the Americas to the east.
The ocean is known for its diverse marine life, including whales, sharks, dolphins, and various species of fish. The name "Pacific" was given to the ocean by Portuguese explorer Ferdinand Magellan in 1521, who called it "Mar Pacifico," meaning "peaceful sea," due to the calmness of its waters at the time.
However, the ocean is not always peaceful and is prone to natural disasters such as typhoons, hurricanes, and earthquakes due to its location on the "Ring of Fire," a region of intense seismic activity.
The Mariana Trench reaches a maximum depth of about 36,070 feet (10,994 meters) and is located on the floor of the western North Pacific Ocean, east of the Mariana Islands. The trench is crescent-shaped and about 1,550 miles (2,500 km) long, with a width of only 44 miles (70 km). It was named after the Mariana Islands, which are nearby.

Sarah thinks that the number of worms on the sidewalk in front of her house increases after a rainfall. Which would be the best way to test her prediction?
Answer:
To collect data about the population of worms before and after the rainfall.
Explanation:
The best way to test her prediction, we have to wait for the rain and collect the data after the rain and before the rain. The difference between shows the result whether she is right or wrong. In my opinion, she is right because the worms comes out from the soil in order breathe. The rain water block the porous spaces in the soil through which the oxygen enters into the soil and the worms can breather so due to blocking no oxygen for them so they come out from the soil after rainfall.
