Answer:
atoms
Explanation:
atoms are the smallest unit of an element
The electron transport chain refers to the transfer of
electrons from electron donors and electron acceptors. After the transfer of
electrons, these electrons then couple with protons (H+ ions) across a
membrane. In eukaryotic cells, electron transport chains occur within the
mitochondrial membrane where it serves as the site of oxidative phosphorylation
that uses ATP as its energy source.

The molecular oxygen is the final acceptor of electrons in an
electron transport chain. This type of transport is used by the cell in
extracting energy through redox reactions that occur during photosynthesis,
sugar oxidation, and cellular respiration. </span>
Answer:
transformation
Explanation:
Transformation is one of the three methods of genetic recombinant in bacteria. The other two are transduction and conjugation. Transformation occurs when the bacterial cells take up the DNA and which in turn changes their phenotype.
Transformation requires that there should not be any cell to cell contact. In the experiments performed by Griffith, the heat-killed virulent S strains were mixed with live R strains. The R strain took the DNA of heat-killed S strains which in turn converted them into the virulent strains. Since this horizontal gene transfer did not include any cell-to-cell contact, he called the process transformation.
Answer:
In order below the answers:
Homozygous males
heterozygous females
curly wings
dark bodies
curly wings and dark bodies
homozygous recessive
heterozygous
straight winged flies
Answer:
Humans produce few offspring slowly.
Explanation:
One of the reasons that patterns of inheritance in humans cannot be studied as easily as in peas or fruit flies is our generation time is approximately 20 years. Is it is about three months in peas and it is about 30 days in fruit flies. All the genes in fruit flies have been mapped. Not all of the genes in humans have been mapped.
