One reason is because the short days and long nights prevent the earth from warming up, another reason could be because the sun's rays in winter are more spread out thus minimizing the amount of energy
Answer:
1/(5⁹) or 5⁻⁹
Explanation:
This is a Mathematics question rather than a Biology question.
The given fraction is:
This fraction can be rewritten as:
Therefore, the quotient of the given fraction is 1/(5⁹) or 5⁻⁹
Answer:
DNA restriction enzymes cut the DNA molecule, while DNA ligases join the resulting DNA fragments
Explanation:
Transformation is a naturally occurring process by which bacteria incorporate exogenous genetic material from their surrounding environment. This process (transformation) is used for DNA cloning via plasmid vectors. In DNA cloning, transformation occurs after restriction enzymes cut the DNA at specific sequences named palindromic sequences (i.e, sequences that can be read the same in opposite direction). Restriction enzymes can generate sticky-ends, where enzymes make staggered cuts in the two strands (e.g., <em>BamH</em>), or blunt ends, where the resulting strands are of the same length (e.g., <em>HaeIII</em>). In general, sticky-end enzymes are more useful because they generate a 3' overhang in one molecule and a complementary 5' overhang in the other, increasing the yield and specificity of ligation. During ligation, a DNA ligase is used to join both DNA strands by forming phosphodiester bonds in the plasmid. Following transformation, bacteria can be selected on antibiotic plates.
Answer:
The correct order is
E. Adsorption
B. Penetration
D. Synthesis
A. Assembly
C. Lysis
Explanation:
Virus can have two reproduction cycle that is lytic and lysogenic. In the lytic cycle first step is virus adsorption or attachment on the host cell surface. The second step is penetration in which the virus penetrated the host cell and injects its genetic material in the host cell.
The third step is synthesis, in this stage, the viral genome gets incorporated and produces viral proteins required for capsid formation. The fourth step is assembly in which viral protein assembled around viral nucleic and form new viruses.
The final step is lysis where the new viruses lyse the host cell to come out of the host cell and infect other cells.
Those states would be Wyoming, Colorado, Utah, New Mexico, California, Arizona, And Nevada
The Upper Basin States being Wyoming Colorado Utah and New Mexico
The Lower basin states being Cali Az and Nevada
