Answer:
Like other organs, leaves are often modified for functions other than photosynthesis. Tendrils of plants are leaves modified for support. In some plants the entire leaf is a tendril,
photosynthesis in these plants is delegated to leaflike structures called stipules at the base of each leaf.
D is the correct answer because the capital letter represents the dominant allele. All of the plants are pure bred. The first pea plant is short (tt) with purple flowers (PP). The second is tall (TT) with white flowers (pp). Therefore the cross is ttPP x TTpp
Answer: The percentage of the helium will increase with the decrease in the percentage of the hydrogen.
Explanation:
The conversion of the hydrogen into helium occurs by the nuclear fusion of the hydrogen atoms. This process reduces the hydrogen density and reduces the energy production inside the core region. Typically, in the core region of the hydrogen is converted into the helium by nuclear fusion. Four hydrogen atoms are collectively fuse to form one atom of helium. This process involves the production of heat energy.
