Answer:
Hypothesized causes for the declines include habitat destruction (the most obvious cause), climate change, pathogens, introduced exotic species, pollution, and increased UV radiation. These agents may act alone or in combination to contribute to the decline of amphibian populations.

Answer:
In the semi-conservative method of DNA replication, each of the strands of the double helix acts as a template for replication.
Explanation:
Semi-conservative DNA Replication:
- Semi-conservative DNA replication produces two daughter helices from the original parent helix. One strand of the daughter helix is form the original template while the other is newly synthesized.
- This means that one strand will have the base sequence identical to the parent, while the other will be complementary to the template.
- This model was experimentally confirmed by an experiment conducted in 1958 by Meselson and Stahl. They used radioactive isotope of nitrogen i.e. N-14 or N-15. DNA molecules made with N-15 were allowed to replicate in the presence of N-14.
- After first replication, DNA molecules contained both N-15 and N-14 isotopes, disproving the conservative model that stated that the new helices are completely identical to the template.
- The second replication yielded only N-14 which disproved the dispersive model that the new helices are a combination of both the template and new strands.
Synergistic describes the relationship between the deltoid and sits muscles during shoulder abduction
Things that originate, result from or otherwise include synergy are referred to as synergistic. synergistic describes a situation in which a combination of factors results in a stronger outcome than would have been the case had the impacts of each factor been added up separately.
A synergistic relationship exists when two individuals contribute more as a team than they would separately. Co-creating outcomes are the foundation of synergistic interactions. Each individual in a synergistic relationship asks questions about the other. They are curious and interested in one another as well as their surroundings.

It depends on the disease. some disease like coronavirus spreads through spit or sneezing on someone. Other diseases like diabetes or cancer are spread genetically. Other diseases can be spread through germs or even airborne.
The most likely conclusion the student will make would be that increasing temperature increases the rate of reaction.
<h3>Effects of temperature on reaction rates</h3>
The rate of reaction of a system is directly proportional to the temperature of the system.
This is because the kinetic energy of the reactant's molecules is increased by increasing the temperature of the system. Thus, reactant molecules collide more and this leads to more reactions.
Thus, increasing the temperature of a system moderately also increases the rate of reaction in the system. Too much increase in temperature, however, can destroy the structures of reactants.
