Answer:
Na and K
Explanation:
Every elements in the same group have similar chemical characteristics
Answer:
The reason why the genotype and phenotype frequences do not match is just because the 1) The genotype based on genes observation,while the phenotype based on physical appearance of the organism externally
Explanation:
the genotype is looking on the arrangement of genes in pair and get its frequency ,while phenotype the external physical appearance of organism is observed to get frequency
Answer:
Pili
Explanation:
The sex of bacteria is determined by a structure called Pilli. Pilli is not present in all species of bacteria, but within species that have this structure, such as Escherichia coli, pilli is considered an appendage present in male bacteria.
Pilli presents itself as a long hair and can also be called F factor or fertility factor and has a reproductive function, as it allows the conjunction between two bacteria (one with pili and the other without), where the male bacteria transmit genetic resources to within the body of the female bacteria , which will combine these resources with its own resources and will give rise to another bacteria.
Answer:
Marine ecosystem have biotic organisms like phytoplankton and photosynthetic algae that do photosynthesis and converts the atmospheric carbon dioxide into organic matter most of the carbon dioxide is released when other organisms eat phytoplankton and release the carbon dioxide through respiration.
But some of the algae and phytoplanktons die naturally get down to the bottom of the ocean where they make carbon sink. Some organisms accumulate CO₂ in their exoskeleton that is made up of calcium carbonate.
Therefore this use of carbon by living organisms in oceans brings carbon dioxide from the atmosphere to oceans. This is why the ocean plays a critical role in the carbon cycle and called carbon sink.
