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.

The organs represented in the image are the Brain, nerve, and spinal cords that monitor and react to changes in the body and its environment.
<h3>What are Organs?</h3>
Organs may be defined as an assemblage of tissues that structurally construct an operational unit specialized to accomplish a distinct operation and functions in the body of a living organism.
The nerves function in sending and receiving signals to the brain from external stimuli. They give the perception of feeling pain, relaxation, stress, etc to the brain according to the situations.
The complete question is as follows:
The picture shows an organ system in the human body.
Brain, Nerve, and spinal cord.
What do these organs do in the human body?
- They filter pathogens and dead cells out of lymph before it returns to the blood.
- They monitor and react to changes in the body and its environment.
- They release hormones that control the activities of cells and organs.
- They identify and destroy things that are foreign or harmful to the body.
Therefore, the correct option for this question is B, i.e. They monitor and react to changes in the body and its environment.
