Answer:
The necessary structure for asexual reproduction
Explanation:
That instant ... typically some moment on june 21 or 22 ... marks
the beginning of the northern hemisphere Summer.
3) C. Stomata, as I explained in my previous answer.
4) B. Nonvascular, low-hanging plants living in moist environs don't have to fight gravity nearly as much as tall ones do. So they needn't highly developed vessels to transport to their tips
5) B. Gravity, see above. The higher trees/plants grew, the further their apical structures were from ground water sources, so the lignin-supported, strong vascular tissue (phloem) allows the transport of water against gravity, using a capillary method (benefiting from the adhesive effect of water molecules).
Answer:
Explanation:
First-generation (F1) progeny only showed the dominant traits, but recessive traits reappeared in the self-pollinated second-generation (F2) plants in a 3:1 ratio of dominant to recessive traits. Mendel then crossed these pure-breeding lines of plants and recorded the traits of the hybrid progeny
Explanation:
-the specific binding of a region of the protein to solutes or a substrate
Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers or function as receptors.
These include receptor proteins that bind specifically to molecules called lingands; some also use channels which respond to chemical signals by modifying solute-specific regions that aid in regulating ion exchange, through the hydrophobic layer of the plasma membrane.
