Some igneous rock forms from magma that cools slowly within Earth’s crust. Briefly describe the most likely crystallization and texture of the rock. Other igneous rock forms from lava that cools quickly on Earth’s surface. Classify the rock as either intrusive or extrusive, and identify another word used to describe this type of rock.
You are studying a sample of igneous rock. The rock formed on the surface of Earth. It’s made mostly of light-colored minerals. The sample has just a few specks of dark-colored minerals. Classify the rock by type and composition.
You are studying a sample of igneous rock. The rock formed within Earth’s crust. The sample contains a very high concentration of dark-colored, high-density minerals. Classify the rock by type and composition.
A scientist shows you a sample of rock called gabbro. The scientist explains that gabbro is an intrusive mafic igneous rock. Explain what this means.

poor water quality affects most estuarine organisms, including commercially important fish and shellfish. the pollutants that have the greatest impact on the health of estuaries include toxic substances like chemicals and heavy metals, nutrient pollution (or eutrophication), and pathogens such as bacteria or viruses.

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure

answer: i don't know

explanation:

you need to provide a picture, otherwise i can't tell you.

if you can provide one, i'd be more than happy to you with this!
