Bees with short tongues are able to obtain nectar from deep flowers by drilling holes in the base of the flower without visiting
Nuetrik [128]

Answer:

The proportion of plants with deep flowers in future generations will decrease and will be very low.

Explanation:

To analyze this, we need to keep in mind the pollination process and the following general ideas:

  • Bees with long tongues can obtain nectar from deep flowers by visiting the top of them and extending their tongues to their bottom.
  • During their visit to the flowers and their search for nectar, long-tongued bees transport pollen from flower to flower, favoring pollination.
  • Bees with short tongues can obtain nectar from deep flowers by drilling holes in their base without visiting their tops.
  • Short-tongued bees do not need to access the nectar by the top of the flower. They do not get in contact with stamens, so they do not play a pollinator roll.
  • In a particular environment, bees with short tongues replace bees with long tongues.

In this particular environment, long-tongued bees used to visit plants with deep flowers to get their nectar. They used to get in contact with mature stamens and carry the pollen on their bodies to the next flower. During this process, long-tongued bees were able to ensure pollination and helped to keep a high reproductive rate of plants with deep flowers.

When shorted-tongue bees arrived at this environment, they were able to replace long-tongued bees. They also looked for the nectar of deep flowers, but instead of visiting them from the top, they were adapted to obtain nectar by drilling holes in the flower base. In this way, they missed the contact with mature stamens and pollen.

Long-tongued bees disappear, and short-tongued bees did not play a role in the pollination process of deep flowers, then the reproductive rate of these vegetable species probably started to decline.

Probably, with time, the proportion of plants with deep flowers in an environment dominated by short-tongued bees will be very low.

Resource partitioning

Resource partitioning refers to differences in resource use between species regardless of the origin of the differences. Similar species can coexist in the same ecological community without one pushing the others to extinction through competition. Species compete for the same resources which include nutrients and habitats which are the raw materials needed by organisms to grow, live, and reproduce. For the question given above, the divergence in lizards is an example of resource partitioning.

where they execute important functions. The polypeptide chain of these proteins must cross the lipid bilayer. This presents a pr
spin [16.1K]

Answer:

In this case, it is likely that the polypeptide chain assumed an alpha helix configuration because the lipid bilayer did not have beta-barrel proteins.

Explanation:

A polypeptide chain is naturally polar, however, a lipid bilayer is naturally non-polar. This makes it difficult and even prevents the polypeptide chain from crossing a lipid bilayer, since the composition of these two elements does not allow them to mix. In that case, the polypeptide chain has two options to take to successfully cross the lipid bilayer.

The first option that the polypeptide chain has is to allow the creation of twisted beta sheets in the shape of a closed barrel in its structure. This only works if the lipid bilayer has beta barrel proteins in its composition to act as a transport channel for the polypeptide chain. However, few lipid layers have this protein.

Most likely, the polypeptide chain assumes an alpha helix conformation to cross lipid bilayers that do not have beta-barrel proteins. By assuming the beta conformation, the polypeptide chain reinforces the hydrogen bonds present in its composition, allowing it to cross the lipid bilayer without having its conformation and structure disassembled.
