Answer: Carbon is one of the essential gases in nature,couple of natural processes causes the release of carbon. Some of the processes include;
- When the remains of producers are broken down by decomposers in the ecosystem.
- When animals break down food molecules to obtain energy, carbon is released.
- When the remains of consumers in the ecosystem are broken down by soil decomposers, carbon is released.
Answer:
TRANSCRIPTION
Explanation:
Transcription is the first process that occurs in the expression of a gene. It involves the synthesis of a mRNA molecule from a DNA template. The DNA molecule, which is located in the nucleus of an eukaryotic cell, is bound to by an enzyme called RNA polymerase in order to synthesize an mRNA molecule/strand.
RNA polymerase synthesizes a mRNA molecule using complementary base pairing rule i.e. Uracil base (U) is synthesized when Adenine (A) is read, Adenine when Thymine (T) is read, Guanine (G) when cytosine (C) is read, Cytosine when guanine is read. These nucleotide bases are then joined together via chemical bonding.
In a nutshell, RNA polymerase catalyzes the formation of a bond between the backbone sugar of one nucleotide base to the backbone phosphate of another nucleotide base in the metabolic process of TRANSCRIPTION.
Answer:
The likely explanation is that population 1 had traits which were more favorable to its survival than population 2's in the new conditions. It wouldn't have to do with food competition, but the traits they already have that may or may not be conducive to their survival in the new conditions.
Explanation:
Let me explain. Say a drought occurred on an island. Population 2 relied on eating bugs that lived in the green grasses. Population 1 relied on eating cactus fruit, which is drought-resistant. Say that because of the drought, population 2 started to decrease since there were less bugs to eat because the grasses dried up. Population 1 is unaffected because the bugs they eat were still in abundance.
This all has to do with the concept of natural selection. Species with traits that are good for their environment will likely do well unless a change in conditions occurs which makes their traits no longer favorable.
Hope that makes sense!

Neurotransmitter are biochemicals and compounds transported from one neuron to another.
Neurons are specialised cells that have dendrites, axons and terminal buttons that sends and receives stimuli from the environment and transduces it into a meaningful information and understand the complexities which the brain now functions.
