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;
- large-scale changes in chromosome structure
Explanation;
-Alterations to chromosome structure or changes in the number of copies of chromosomes in a cell.
-Allele frequencies in a population may change due to four fundamental forces of evolution: Natural Selection, Genetic Drift, Mutations and Gene Flow. Mutations are the ultimate source of new alleles in a gene pool. Mutation is important as the first step of evolution because it creates a new DNA sequence for a particular gene, creating a new allele.
Answer:
In more subtle ways, atmosphere-biosphere interactions influence the health of the air we breathe (see figure): rough surfaces of vegetation remove aerosols, ozone, and other reactive gases from the air through dry deposition; plants emit a huge variety of volatile organic compounds (VOCs) that are precursors to ..
Neutral lipids are normally associated with which purpose energy storage. <span>Neutral lipids are hydrophobic molecules lacking charged groups which are produced by the dehydration synthesis of one or more fatty acids with an alcohol like glycerol. The examples of neutral lipids are triacylglycerols or sterol esters. Those lipids cannot be incorporated into biomembranes, so they are “packed” in structures called lipid particles (lipid droplets). Upon requirement storage lipids are mobilized from this compartment and degradation products serve as energy sources and/or building blocks for membrane formation.</span>

they are ions of their atom.
