Fertilizer van leach water into fresh water, adding extra, unwanted nitrates. This will increase algal population which can cause algal blooms. Algal blooms reduce light levels, killing aquatic plants. These dead plants, as well as dead algae, become food for bacteria which increase greatly in number.

How do you think the rock layers and fossils found in Red Rock Canyon can provide evidence for Earth's geologic history?

Bogdan [553]

Answer and Explanation:

Red Rock Canyon is an area of universal geologic interest, located a few miles west of Las Vegas within the Mojave Desert. Many experienced geologists visit the Red Rock; they are surprised by the vivid colors of rocks, natural beauty, and rock formations. A visual display takes million years to make the masterpiece known as the Red Rock Canyon National Conservation area. About 500 million years ago, Red Rock Canyon was found at the bottom of an ocean basin. Limestone accumulated in this ocean basin, which contains the fossils of sea life. The tracks of two-footed meat-eating dinosaurs have been found in the Aztec Sandstone. The tracks of small animals such as spiders, scorpions, early mammals, and proto-mammals were also found. The fossils and rock layers that are found in Red Rock Canyon provide evidence for Earth’s geologic history. Paleontologists are still searching these areas.

If the question was actually pointing these (thyrotropin-releasing hormone TRH gonadotropin-releasing hormone GnRH antidiuretic hormone ADH thyroid-stimulating hormone (thyrotropin) TSH prolactin PRL follicle-stimulating hormone FSH luteinizing hormone LH) as the phrases, then the answer will be

•Thyrotropin-releasing hormone TRH describes ANTERIOR PITUITARY

•Gonadotropin-releasing hormone GnRH describes the HYPOTHALAMUS

•Antidiuretic hormone ADH describes the POSTERIOR PITUITARY

•Thyroid-stimulating hormone (thyrotropin) TSH describes the ANTERIOR PITUITARY

•Prolactin PRL describes the ANTERIOR PITUITARY

•Follicle-stimulating hormone FSH describes the ANTERIOR PITUITARY

•Luteinizing hormone LH describes the ANTERIOR PITUITARY

Explanation:

but if the phrases were to be this

1. Releases oxytocin

2. Synthesizes and releases PRL

3. Synthesizes and releases TSH

4. Synthesizes some hormones that are released into blood vessels bound for another gland

5. Regulated by hormones released into portal blood vessels

6. Is an extension of the Hypothalmus

7. Synthesizes oxytocin and ADH

8. Integrates nervous and endocrine systems

(...as found from another source),

the answers will be

What happens during photosynthesis

DaniilM [7]

Light energy is absorbed by chlorophyll, a green substance found in chloroplasts in some plant cells and algae. Absorbed light energy is used to convert carbon dioxide (from the air) and water (from the soil) into a sugar called glucose. Oxygen is released as a by-product. - BBC
