Q: Answer the following question given this paragraph: Invertebrates are animals that lack a vertebral column, or backbone. All the phyla in Table above , except the Phylum Chordata, consist only of invertebrates. Even the Phylum Chordata includes some invertebrate taxa. Invertebrates make up about 95 percent of all animal species. Q: Invertebrates make up what percentage of all animal species? A:

OPTIONS:
- 90 percent
- 50 percent
- 30 percent
- 95 percent

A: 95 percent

input: OPTIONS:
- acids
- bases
- enzymes
- hormones Now, answer this question: Answer the following question given this paragraph: You can see an example of a negative feedback loop in Figure below . It shows how levels of thyroid hormones regulate the thyroid gland. This loop involves the hypothalamus and pituitary gland as well as the thyroid gland. Low levels of thyroid hormones in the blood cause the release of hormones by the hypothalamus and pituitary gland. These hormones stimulate the thyroid gland to secrete more hormones. The opposite happens with high levels of thyroid hormones in the blood. The hypothalamus and pituitary gland stop releasing hormones that stimulate the thyroid. Q: Low levels of thyroid hormones in the blood cause the release of what by the hypothalamus and pituitary gland? A:
A:
output: hormones
