Processing Minerals and Metals
10.
Organize Information Fill in the flowchart with the main steps involved in
processing minerals,
Minerals are
removed from
the ground
11. Why are minerals processed?
12. What are tailings, and why are they so controversial?
Answer:
To remove impurities.
Explanation:
Minerals are processed in order to remove impurities from the minerals as well as getting clean minerals. If the minerals are not clean from impurities, it can't be used in the manufacturing of other products. Tailings are the materials that left over after the process of separating the mineral from the uneconomic fraction or residue of an ore. Tailing stored in water can be dangerous sources of toxic chemicals, such as heavy metals, sulfides and radioactive content that can adversely affected the biotic or living part of water.

Gaining Insight into Depositional Environments of Sedimentary Rocks
Name: ________ Course:____________
Section:_______ Date:_____________
Sedimentary structures, fossils, cements, and other features of sedimentary rocks provide insight into the environment in which the sediment was deposited.
Match each of the features in the left-hand column to an aspect of the depositional environment listed in the right-hand column by placing the corresponding letter in the proper blank.
Rock and/or feature of the rock
(a) poorly sorted arkose
(b) contains fossils of intact coral
(c) red mudstone containing dinosaur footprints
(d) black shale containing some pyrite crystals
(e) sandstone containing symmetrical ripples
(f) cross-bedded sandstone
(g) contains > 50% carbon and fossil leaves
(h) contains large, rounded pebbles and cobbles (contains fossils of feathers G very angular grains
Aspect of the depositional environment
1. deposited in a desert dune or in a current
2. formed from sediments accumulated in a swamp
3. deposited in very quiet (stagnant) water
4. deposited in an anoxic marine setting
5. deposited by a swiftly moving stream
6. formed from warm-water, shallow marine reef
7. has not undergone a lot of transport immature,
8. deposited close to the source
9. formed from terrestrial mud (riverbank deposits)
10. deposited on a beach
Answer:
(a): 7. and 8.
(b): 6.
(c): 9.
(d): 4.
(e): 10
(f): 1.
(g): 2.
(h): 5. and 3.
Explanation:
Sedimentary rocks are rocks generated from pre-existing rocks and/or once-living organisms. Arkose is a type of sandstone rich in feldspar (at least 25% of this mineral). Moreover, a rock containing coral fossils indicates that its depositional environment was located in warm tropical reef waters. Mudstone is a kind of sedimentary rock composed of clay (in this case, sediments continued to be deposited above the dinosaur footprints). The black shales are fine-grained sedimentary rocks composed of a mixture of clay (in this case, the pyrite crystals are used as an indicator of low oxygen). Symmetrical ripple marks in the sandstone indicate a marine environment where water motion was dominated by wave oscillations. Cross-bedding is a common structure of sedimentary rocks that form during deposition on inclined surfaces of bedforms (e.g., ripples and dunes). Sediment deposition in swamps is usually heavily vegetated and therefore they are rich in organic matter, while deeper swamp sediments are generally anoxic. Finally, cobblestones are naturally occurring cobble-sized stones formed from the flow of water and gathered from stream beds, while pebblestones are formed when water bodies hit the giant rocks in the rivers and lakes.

How can human beings work to combat and reduce the many negative impacts to the planet?
I
Answer:
Use more renewable resources (solar, wind, hydroelectric, etc) and fewer fossil fuels (coal, petroleum, and natural gas), since fossil fuels produce a lot of carbon dioxide Eat less livestock (farm animals, such as cows, produce a lot of methane and waste) and possibly become vegetarian/vegan Decrease deforestation (trees absorb carbon dioxide and release oxygen)Recycle/reuse more items to decrease the amount of trash in oceans, forests, and other ecosystems1, name the part of the reproductive system in which fertilisation happens.
2, what is an embryo
3, where does the embryo develop into a foetus, and then a baby
4, why does the uterus lining start to grow thick and spongy, as an egg cell develops in an ovary
5, what happens to the uterus lining if the egg cell is not fertilised
6, how often does an egg cell leave an ovary, in an adult woman
7, how often does menstruation happen, in an adult woman
Answer:
°•°
Explanation:
1.fallopian tube
2.an unborn or unhatched offspring in the process of development, in particular a human offspring during the period from approximately the second to the eighth week after fertilization (after which it is usually termed a fetus)
3.First, the zygote becomes a solid ball of cells. Then it becomes a hollow ball of cells called a blastocyst. Inside the uterus, the blastocyst implants in the wall of the uterus, where it develops into an embryo attached to a placenta and surrounded by fluid-filled membranes.
4.Eggs live in ovaries, and the hormones that control your menstrual cycle cause a few eggs to mature every month. When your egg is mature, it means it's ready to be fertilized by a sperm cell. These hormones also make the lining of your uterus thick and spongy, which gets your body ready for pregnancy.
5.The fertilized egg attaches to the lining of the uterus. The placenta then develops. The placenta transfers nutrition and oxygen to the fetus from mother. If the egg does not become fertilized, the lining of the uterus (endometrium) is shed during menstruation.
6.The egg cell travels down the fallopian tube into the uterus. The moment the egg cell leaves the ovary is called ovulation. Once a girl has had her first monthly period, ovulation usually occurs once a month
7.The average menstrual cycle is 28 days long. Cycles can range anywhere from 21 to 35 days in adults and from 21 to 45 days in young teens. The rise and fall of levels of hormones during the month control the menstrual cycle.
The owners of a local bakery ask for your help in improving a special yeast strain they use to make bread. They would like you to help them design experiments using RNA interference to turn off genes, to allow them to test their hypothesis that certain genes are important for the good flavors found in their bread. Of the components in the following list, which is the most important to check for in this yeast strain if you would like this project to succeed?
a. the presence of foreign double-stranded RNA
b. the presence of genes in the genome that code for RISC proteins
c. the presence of miRNA genes in the genome
d. the presence of single-stranded siRNAs within the cell
Answer:
b. the presence of genes in the genome that code for RISC proteins
Explanation:
The RNA interference (RNAi) mechanism is a naturally occurring pathway by which eukaryotic cells can silence specific genes both at the transcriptional (eg., by triggering DNA methylation on specific loci) and posttranscriptional (e.g., by triggering mRNA degradation) levels. This mechanism (RNAi) is widely used in molecular biology laboratories in order to silence genes and thus understand their functions. During the RNAi pathway, double-stranded RNAs (dsRNAs) are cleaved into small double-stranded RNA (dsRNA) molecules known as small interfering RNAs (siRNAs) or microRNAs (miRNAs) by an enzyme referred to as "Dicer". Subsequently, these small non-coding RNAs bind to an enzymatic complex known as RNA-induced silencing complex (RISC) that contains a ribonuclease enzyme, i.e., an enzyme that degrades RNA. Finally, the small non-coding RNA (either siRNAs or miRNAs) that are complementary to the RNA target directs the RISC complex to bind and cleave specific mRNAs, thereby silencing gene expression (in this case, by the inhibition of protein translation).

Cómo se denomina al tipo de acción metabólica que genera la glucólisis y respiración celular?
Answer:
catabolismo.
Explicación:
El tipo de acción metabólica que genera la glucólisis y la respiración celular se llama catabolismo porque en ambos procesos se descomponen las moléculas lo cual es una acción catabólica. El catabolismo es una forma de metabolismo que descompone moléculas más grandes en unidades más pequeñas que son utilizadas por la célula para liberar energía o utilizadas en otras reacciones anabólicas significa la síntesis de moléculas complejas en organismos a partir de otras más simples.
PLEASE HELP! I WILL GIVE BRAINLIEST. What 2 factors affect organisms and their habitats, and give examples of each
Answer:
There are two categories of these factors: abiotic and biotic. Abiotic factors are the non-living parts of the environment that can often have a major influence on living organisms. Abiotic factors include water, sunlight, oxygen, soil and temperature.
Explanation:
Biotic factors are interactions associated with living organisms. They can also influence the distribution of organisms in an ecosystem. grazing - too little leads to dominant plants outcompeting other species, too much reduces species numbers overall. Both decrease biodiversity.
Abiotic factors affect the ability of organisms to survive and reproduce. Abiotic limiting factors restrict the growth of populations. They help determine the types and numbers of organisms able to exist within an environment.

Answer:
Try this website: https://www.fs.fed.us/wildflowers/pollinators/What_is_Pollination/syndromes.shtml
Explanation:
Transcriptional termination by RNA polymerase is favored when tryptophan levels are low (1) / high (2), because the low levels (3) / abundance (4) of charged Trp-tRNATrp causes the ribosome to quickly synthesize the leader polypeptide (5) / stall at the pair of Trp codons (6). This termination (7) / elongation (8) structure forms because the 3-4 stem loop (9) / the ribosome (10) allows region 2 to pair with region 3.
a. 1,3,6,8,9.
b. 2,3,5,8,9.
c. 1,4,6,7,10.
d. 2.4,5,8,10.
e. 2.4.5.7.9.
Answer:
The answer is "Choice e".
Explanation:
The additional Trp Operon function is gene expression attenuation. If tryptophan levels are high, RNA Polymerase endings of glutamate operone are favoured, since the excess of Trp-tRNATrp load causes rna to rapidly synthesise the lead polyprotein and region iii base pairs with cluster 4 and creates stepping chain structures which signal mrna cessation. Rest both options are wrong in regards to the glutamate operon amplification transmission termination mechanism.
