The greatest threats to coral reefs is the rising temperature of the oceans as a result of climate change and the acidification of the oceans due to increased levels of carbon dioxide in the atmosphere which dissolves in the ocean and forms carbonic acid.Aug 3, 2015
Photo 51 is an image of the DNA structure that was used to create a DNA template. Rosalind Franklin managed to photograph a DNA molecule.
<h3>Who took the first DNA picture?</h3>
During the four years she spent in France, Rosalind Franklin perfected herself in the use of x-ray crystallography, a technique used to create images of microscopic elements. It was through her that, already at King's College, chemistry managed to photograph a DNA molecule.
With this information, we can conclude that Photo 51 is an image of the DNA structure that was used to create a DNA template. Rosalind Franklin managed to photograph a DNA molecule.

#SPJ1
Answer:
C.
Explanation:
The small population size means that the new colony may have reduced genetic variation from the original population and that variation, in this case, included the dominant allele for Huntington's disease. Genetic drift, along with natural selection, mutation, and migration, is one of the basic mechanisms of evolution. In this case, it was a chance that the settlers all carried the allele for Huntington's disease.
Answer:
c. Grasses and small shrubs would be the first plants to begin growing from the seeds that are in the soil.
Explanation:
This question depicts SECONDARY SUCCESSION, which is one of the two types of ecological successions where an area previously occupied by living organisms is disturbed by natural causes such as hurricanes, tornadoes etc. This is the case in this question where thunderstorms that lead to tornadoes leave a significant impact on the environment of the southeastern part of the United States.
According to the question, the tornado results in the uprooting of previously existing trees that has occupied that area. After the devastating effect of the tornado on the environment, changes occur rapidly since the soil of the environment are already rich in nutrients. The first plants to recolonize in secondary succession are annual plants consisting of grasses and shrubs whose seeds were not destroyed by the tornado. These forms of plants can also be called PIONEER species as far as secondary succession is concerned.
Hence, based on the question, grasses and small shrubs would be the first plants to begin growing from the seeds that are in the soil.
the answer is no. You need the two torques to equal in order to lift something. That is 9 X 2 = lifting torque and 9 X 3 = lifted torque.
As you can plainly see 18 < 27; so you cannot lift that 9 N weight located 3 meters from the fulcrum.
