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.

Answer:

Every object has a total energy which is the sum of its kinetic and potential energy:

E = Ek + Ep

Kinetic energy is, as the name suggests, the energy of moving. It is given through the equation:

Ek = m • v^2 / 2

From here, we can see that Ek depends on the object's velocity; if v=0, then Ek will also be zero.

Potential energy is the energy an object has on a certain height:

Ep = m • g • h

Obviously, if the height is zero, then the Ep=0 too.

Another important thing to note is that E is always constant; if Ek increases (or decreases), Ep will decrease (or increase) so that their sum will always be a constant value.

If the bowling ball sits at the top of the 40 meters tall building, it has no velocity, it doesn't move, but it is located on a certain height.

That means that, at the top of the building, the bowling ball has no kinetic energy:

E = Ep + Ek

- no velocity ---> Ek =0

E = Ep = mgh

Ep = 2 kg • 9.81 m/s^2 • 40 m

E = Ep = approximately 785 J

To conclude, at the top of the building Ep > Ek.

Now, the ball is falling, and it's halfway down and it's travelling 19.8 m/s. Now, its kinetic energy is:

Ek = m • v^2 / 2

Ek = 2 • 19.8^2 / 2

Ek = approximately 392 J

Now, since the ball is halfway down, that means that its height is 20 meters. So, its Ep is:

Ep = mgh

Ep = 2•9.81•20

We already stated that total energy is constant and that is the sum of Ep and Ek and that it is around 785 J. We could also find Ep:

Ep = E - Ek

Ep = 785 - 392

Whichever way we use to calculate, we'll get the value of approximately 392 J.

That means that, halfway down, Ep=Ek.

Since the ball is halfway down, that means that its Ep is half the value it was while at the top of the building. The other half is used on the ball's velocity producing kinetic energy. That's why these two are equal at the halfway down.

Just before it hits the ground, the bowling ball has no height, meaning it has no potential energy. That also means that its total energy is equal to its kinetic energy:

E = Ep + Ek

Ep = 0

E = Ek

We already said that the ball's total energy was around 785J, so its kinetic energy just before it hits the ground will be that exact value.

List 3 benefits of the development of seeds and fruits.

Anna11 [10]

Explanation:

The fruits protect the seeds enclosed in the ovary. The seeds mature in the fruit by taking essential requirements.

The mature seeds retain the capacity of germination for a long period. It may be dispersed individually or along with the fruits to long distances by different agencies. The seeds germinate in the favorable conditions.

These are the advantages of fruits and seeds in the Angiosperms. These advantages help the spread of the Angiosperms in different climatic conditions. Thank you
