Answer: A. Spruce trees reduce the sunlight available to young pine trees, thus decreasing the environment's carrying capacity for pine trees.
Explanation:
Carrying capacity is the maximum number of the members of the population of a species which an ecosystem can sustain in terms of availing the resources. The population size will be affected when the carrying capacity does not meet the demand of the population.
In the given situation, the pine trees requires the sunlight to mature whereas the spruce trees requires the shade to get mature. If the spruce trees are taller than the pine trees they are likely to reduce the available sunlight of the young pine trees. Hence, the environmental carrying capacity for pine trees will decrease in the absence of proper sunlight.
Answer:
A. They are ductile and malleable
Explanation:
Although they have luster/shine they can be be dissolved in water and in acid so it can not be all of the above. They are malleable so they can be easily be made into jewelry.
A fracture in the shaft of a bone would be a breaking the diaphysis.(dia- through, physis=growth). Diaphysis or shafts forms the long axis of the bone.
Diaphysis is the main or mid section of a long bone. It is made up of the cortical bone and usually contains bone marrow and adipose tissue. It is a middle tubular part composed of compact bone which surrounds a central marrow cavity which contains red or yellow marrow.
I think the correct answer from the choices listed above is option D. Venter's contribution to science is the invention of a synthetic cell. Craig Venter and his team have built the genome of a bacterium from scratch and incorporated it into a cell to make what they call the world's first synthetic life form.
