D because the common types of phytoplankton is cyanobacteria,
silica-encased diatoms, dinoflagellates, green algae, and chalk-coated coccolithophores.
Neurotransmitters are broken down by enzymes in order to avoid over-stimulation of a neuron and to allow for the transmission of impulse another impulse by the neurons.
<h3>What are neurotransmitters?</h3>
Neurotransmitters are chemical substances which are released at neuronal ends and which help transmit sction potential from one neuron to another.
After the transmission of impulse between the neurons, neurotransmitters ate broken down by enzymes.

Answer:
Species a and c
Explanation:
The species c, was more closely related to species a than species b was. This is because species a and c just recently evolved into different species in evolutionary history.
Hi this would be called the blind spot. Hope this helps.
Answer and Explanation:
A gene is a section of DNA. The change in the sequence of the DNA is known as mutation. Mutation always changes the sequence of the DNA. Sunlight can cause mutation. Sunlight produces structures named thymine dimers. Thymine dimers produce twist in the shape of DNA. These twists make DNA hard to copy, which can lead to mutation. It is essential to use sunscreen to block UVA and UVB rays to prevent thymine dimers from emerging in our cells. The US Food and Drug Agency recommends an SPF (sun protection factor) to defend against skin aging and skin cancer. X-ray radiation is a form used in x-rays. The energy level of the X-ray radiation is very high that can produce free radicals. Free radicals can steal electrons from DNA that can cause mutation. By using medical images, we can decrease exposure to X-rays. Less exposure to X-rays prevents mutation and also prevents the production of gene protein in other body parts.
