Dinoflagellate is a type of neurotoxin which is found in the red-tide algae.
The answer is:
d. people can get paralytic shellfish poisoning during dinoflagellate blooms
Dinoflagellate algal blooms, during red-tide, release strong neurotoxins that can be ingested by shellfish and passed on to humans who eat the infected shellfish. The most significant public health problem that has been known to cause this harmful algae poisoning is: Amnesic Shellfish Poisoning (ASP).
Answer:
Hypothalamus and anterior pituitary gland.
Explanation:
Lower levels of T3 and T4 in the blood or lower metabolic rate serve as signal and stimulate the release of thyrotropin-releasing hormone (TRH) from the hypothalamus. The TRH stimulates the anterior pituitary gland to release thyroid-stimulating hormone (TSH) which in turn makes the thyroid gland to release the thyroid hormones.
The elevated levels of thyroid hormones inhibit the release of TRH from the hypothalamus and that of TSH from the anterior pituitary gland.
Hence, the cells of hypothalamus and anterior pituitary gland would be inhibited by the binding of thyroid hormone to regulate the release of these hormones by a negative feedback mechanism.
Answer:
False
Explanation:
In eukaryotes, replication begins from multiple origins of replication and the replication forks move bidirectionally to replicate the DNA.
