During nitrogen fixation, bacteria breaks nitrogen gasses down into a usable form for plants.
1. Cellular respiration does not consume carbon dioxide (CO2).
Cellular respiration is a process by which plants produce energy. It consists of anaerobic (without O2) and aerobic phase(with the presence of O2). During the cellular respiration chemical energy derived from the nutrients (like glucose) is transformed into energy molecule adenosine triphosphate (ATP).
2. Unlike photosynthesis, cellular respiration occurs in all eukaryotic organisms (photosynthesis only in plants and some microorganisms). The processes of cellular respiration occur in cytosol (glycolysis) and in the mitochondrion of a cell (Krebs cycle and electron transport chain).
The answer is 2 because its the outside number and not in the parentheses
The correct asnwer to your question - why would a group of antelopes leave the herd for search of a better grassland is an example of emigration - B.
These antelopes would emigrate to a certain grassland and be immigrants in that grassland. This has to be distinguished.
Answer:
This question lacks options, however, it can be answered based on general understanding of the topic
The answer is SUBSTITUTION MUTATION
Explanation:
A mutation is any change that occurs in the nucleotide sequence of a gene. Mutation can be of different types depending on how it occurs. One type of mutation is SUBSTITUTION MUTATION, which is a mutation in which one or more nucleotide base is replaced by another in the sequence.
Nucleotide bases are read in a group of three called CODON. Each of these codons specify amino acid. Hence, if the nucleotide base sequence is altered during mutation, the amino acid sequence is altered likewise. In this case where the original amino acid sequence is: Met-Ala-Gln-Arg-Glu-Leu, the mutation affected the nucleotide bases coding for Arginine (Arg), hence changing it to Glycine (Gly).
This means that a base substitution mutation occured, replacing the amino acid Arginine with Glycine in the mutated sequence.
