How did flowers and fruits contribute to angiosperms becoming dominant land plants on earth?

Biology
1 answer:
Ainat [17]3 years ago
4 0

Answer: The study, by Dr. Tim Brodribb and Dr. Taylor Field of the University of Tasmania and University of Tennessee, used plant physiology to reveal how flowering plants, including crops, were able to dominate land by evolving more efficient hydraulics, or 'leaf plumbing', to increase rates of photosynthesis.

Explanation: The reason for the success of this evolutionary step is that under relatively low atmospheric C02 conditions, like those existing at present, water transport efficiency and photosynthetic performance are tightly linked. Therefore adaptations that increase water transport will enhance maximum photosynthesis, exerting substantial evolutionary leverage over competing species.

The evolution of dense leaf venation in flowering plants, around 140-100 million years ago, was an event with profound significance for the continued evolution of flowering plants. This step provided a 'cretaceous productivity stimulus package' which reverberated across the biosphere and led to these plants playing the fundamental role in the biological and atmospheric functions of the earth.

ehidna [41]

Answer:

Greater than zero, and equal to the rate of the reverse reaction

Explanation:

this is an incomplete question in the first place, i saw the complete format online hence the answer am giving here.

Before any C2H5CO2CH3 is or was removed, the system is said to be in equilibrium.

This means that the rate of consumption of reactants and rate of generation of products are greater than zero and are equal, that means that both the forward and backward reactions are occurs at these rate.

sineoko [7]

Answer;

-The above statement is true

-It is a precaution during dissecting.

Explanation;

Among the precautions  while dissecting include;

-When cutting into or dissecting the specimen, it is important to always cut away from yourself and others. To avoid cutting anyone, especially with formaldehyde being used. .

-You should also should not hold the animals while cutting because you could again, cut yourself.  Another precaution that should be obvious is Do not eat any part of the specimen.
