<span>B. Stamen is the correct answer. It is the only part that
belongs to the male flower. Stamen has anther which is a saclike structure where
pollens are developed and filaments which act as the part of the flower which
transports the pollen. Flowers usually has the same petals as their number of
stamen. Various flowering plants have different types of stamen. Some are
attached to the petals and some are not. When female flowers receive the
pollens from the male flower’s stamen, the flowers reproduce.</span>
Answer:
Degree Heating Week (DHW) shows how much heat stress has accumulated in an area over the past 12 weeks (3 months) by adding up any temperature exceeding the bleaching threshold during that time period.
Answer:
The trend shows that the Enzyme Pepsin is active and prefers the pH level of 2. While Trypsin Is much active at pH 8 and prefers that pH level.
Explanation:
You can tell by seeing the enzyme activity compared to the pH range. Enzymes are simply proteins which work around your body so pepsin since it is active in acidic levels (pH 2) is probably an enzyme found in the stomach.
Each sp2<span> hybrid orbital on a carbon atom contains one electron. Figure 9.21 shows how the four C</span><span>H </span><span> bonds are formed by overlap of </span>sp2<span> hybrid orbitals on C with the 1</span>s<span> orbitals on each H atom. We use eight electrons to form these four electron-pair bonds. The C</span><span>C </span><span> bond is formed by the overlap of two </span>sp2<span> hybrid orbitals, one on each carbon atom, and requires two more electrons. The C</span>2H4<span> molecule has a total of 12 valence electrons, 10 of which form the one C</span>C and the four C<span>H </span><span> bonds.</span>
