Because of this charge increase, the atoms of the alkaline earth metals are smaller and have higher first ionization energies than the alkali metals within the same period. The higher ionization energy makes the alkaline earth metals less reactive than the alkali metals; however, they are still very reactive elements
Photosynthesis is directly responsible for root growth in plants.
C, the cells do not use carbon dioxide they give it off after cellular resparation
Answer:
The Grants wanted to find out whether they could see the force of natural selection at work, judging by which birds survived the changing environment. For the finches, body size and the size and shape of their beaks are traits that vary in adapting to environmental niches or changes in those niches.
The correct answer is B. Honeybee pollinates a flower while gathering nectar.
Mutualism is an interspecific interaction between two species in which both the species are benefited from the interaction. Honeybee visits flower to collect nectar for its food. In the process of collecting nectar, pollen grains stuck to its body. Flower gets pollinated when hone bee visits another flower. Thus, both honeybee and plants get benefit from this interaction.
