<h2>Answer:</h2>
The correct option is B which is plants.
<h3>Explanation:</h3>
Food chain contains:
- Producers: Organisms that produce food for their own and other animals. They convert simpler compounds into complex compounds.
- Consumers: They utilize the food made by the consumers. There primary, secondary and tertiary consumers.
- Decomposers: They convert complex organic compounds into simpler one.
So plants are autotrophic and they are the producers in food chain.
Hence Earth's food chain starts with plants.
Answer:
The energy we get from the food we eat originally came from plants, which absorbed energy from the sun. Photosynthesis is also important because of the oxygen it produces. They recycle the carbon dioxide we breathe out and turn it back into oxygen so that we never run out.
Explanation:
The medulla oblongata is the portion of the brainstem that blends with the spinal cord after passing through the foramen magnum.
The medulla oblongata is the lowest part of the brainstem and is continuous with the spinal cord after passing through the foramen magnum. The medulla oblongata is cone shaped and it contains several nerve cells which controls many autonomic (involuntary) functions such as breathing, sneezing, heart and blood vessel activity, swallowing and digestion. The medulla oblongata is the center for respiration and circulation and it also assist in transmitting messages between various parts of the brain and the spinal cord.
Explanation:
Watson & Crick discovered that DNA is composed of two (2) strands of DNA running antiparallel to each other. One strand is oriented in the 5’ -> 3’ direction while the other is oriented in the 3’ -> 5’ direction. The nitrogenous bases of the strands are found in between the two-strand backbones and they form hydrogen bonding with each other. Specifically, pyrimidines (Cytosine and Thymine) pair with purine (Adenine and Guanine).
The space between the strands is even throughout like a ladder with rungs of equal lengths. However during the twisting on the DNA helix, there are major grooves and minor grooves that form along the helix because of the nature of how the nitrogenous bases are attached to their respective strand. They do not project from their strands at 90 degrees.
