Answer:
A) intensity of light
Explanation:
The independent variable is the thing being changed. A dependent variable is the effect caused by that change
Answer:
Air pollution will increase due to increased use of fossil fuels and the amount of natural space will decrease as suburban areas increase.
Biodiversity generally refers to the variety and variability of life on Earth. According to the United Nations Environment Programme(UNEP), biodiversity typically measures variation at the genetic, species, and ecosystem level.[1] Terrestrial biodiversity tends to be greater near the equator,[2] which seems to be the result of the warm climateand high primary productivity.[3] Biodiversity is not distributed evenly on Earth, and is richest in the tropics. These tropical forest ecosystems cover less than 10 percent of earth's surface, and contain about 90 percent of the world's species.[4] Marine biodiversitytends to be highest along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity.[5]Biodiversity generally tends to cluster in hotspots,[6] and has been increasing through time,[7][8] but will be likely to slow in the future.[9]
Rapid environmental changes typically cause mass extinctions.[10][11][12] More than 99.9 percent of all species that ever lived on Earth, amounting to over five billion species,[13] are estimated to be extinct.lstimates on the number of Earth's current species range from 10 million to 14 million,[f which about 1.2 million have been documented and over 86 percent have not yet been described] More recently, in May 2016, scientists reported that 1 trillion species are estimated to be on Earth currently with only one-thousandth of one percent described.[18]The total amount of related DNA base pairson Earth is estimated at 5.0 x 1037 and weighs 50 billion tonnes.[19] In comparison, the total mass of the biosphere has been estimated to be as much as 4 TtC (trillion tons of carbon).[20] In July 2016, scientists reported identifying a set of 355 genes from the Last Universal Common Ancestor (LUCA) of all organisms living on Earth.[21]
The age of the Earth is about 4.54 billion years.[22][23][24] The earliest undisputed evidence of life on Earth dates at least from 3.5 billion years ago,[25][26][27] during the Eoarchean Era after a geological crust started to solidify following the earlier molten HadeanEon. There are microbial mat fossils found in 3.48 billion-year-old sandstone discovered in Western Australia.[28][29][30] Other early physical evidence of a biogenic substance is graphite in 3.7 billion-year-old meta-sedimentary rocks discovered in Western Greenland.More recently, in 2015, "remains of biotic life" were found in 4.1 billion-year-old rocks in Western Australia.[32][33] According to one of the researchers, "If life arose relatively quickly on Earth .. then it could be common in the universe.
decreased and then increased after major waves of mass extinctions
Answer is.
I think the answer to this is abyssal plane
Answer:
The correct answer is :
- The 2 strands of DNA separate
- mRNA is built based on the DNA template
- tRNA brings an amino acid into the P site.
-
tRNA brings an amino acid into the A site.
-
tRNA leaves the P site and a peptide bond is formed between the amino acids.
- The mRNA+attached tRNA shifts, moving the 6-tRNA from A site to the P site.
-
The entire mRNA strand is translated into amino acids and a polypeptide is formed.
Explanation:
Protein synthesis is a process that is made up of two distinct processes namely transcription and translation.
Transcription: this process include several steps where the segment of DNA which has information, copied into the new molecule called mRNA which acts as the template as it has information copied from the DNA to produce gene expression.
Translation: is the process includes several steps in which a peptide chain is formed from the mRNA with the help of tRNA and ribosomes.
The correct order of steps is given under the answer heading.
