Living components in a river ecosystem would include all plants, all animals, all microorganisms. Every fish species, every arthropod species, every reptile and amphibian species, all the birds, etc.
I guess the stomach is held in place by a variety of Muscle cells, Epithelial cells, and connecting tissues; so the answer is: all of the above.
Answer:
b. average heterozygosity
Explanation:
From the available options:
a. nucleotide variability
b. average heterozygosity
c. average number of loci
d. geographic variability
Nucleotide variability represents a form of genetic variation that occur as a result of difference in nucleotide sequence of deoxy ribonucleic acid.
The locus is a region on the chromosome where genes are located. Average number of locus thus refers to total number of loci per total number of individuals in a population.
Geographic variability refers to difference in genetic traits across the various geographical distribution of a population.
Average heterozygosity is the percentage or proportion of heterozygous individuals for a trait within a population. It is a common measure of genetic variation in a population.
When a mutation occur within a population and this leads to the introduction of a new allele at a locus for which some individuals within the population are homozygous, it will directly affect the average heterozygosity of the population because more individuals will lose their homozygosity and become heterozygous.
<em>The correct option is b.</em>
Explanation:
1. cell membranes are partialy permeable, only allowing passage to some certain molecules.
2. diffusion is the movement of molecules across partially permeable membrane down concentration gradient.
3. the molecules are too big to pass through partially permeable membrane. the concentration of the molecule might be higher in the cell than in the solution/surroundings.
Answer:
Oxidative Phosphorylation
The mitochondria is one of the double membrane organelles with specialized energy-producing functions, that is, reduced nucleotides to finally form the cellular energy currency that is ATP. The 5'-triphosphate adenosine molecule (ATP) is synthesized in the inner mitochondrial membrane as a subsequent step to the electron transport chain through oxidative phosphorylation. This process takes advantage of the flow of protons or proton motive force, detected by an electrochemical differential of H +, to produce ATP through the complex V of the mitochondrial inner membrane. Together with photosynthesis, it is one of the most important energy transduction processes in the biosphere.
Oxidative phosphorylation: Synthesis of ATP
The mitochondria, in its inner membrane, is the place of the electron transport chain and oxidative phosphorylation, | Mitochondrial electronic transport and oxidative phosphorylation are the mechanisms that aerobic organisms use to synthesize ATP from reduced organic molecules.
