how the cardiovascular, respiratory and digestive systems work together to provide cells with the raw materials they need to ensure healthy cell function

Answers

Answer 1

Explanation:

The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.

the ground

11. Why are minerals processed?

12. What are tailings, and why are they so controversial?

Answers

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.

(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

Answers

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.

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.

PLEASE HELP! I WILL GIVE BRAINLIEST. What 2 factors affect organisms and their habitats, and give examples of each

Answers

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.

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

Answers

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).

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.

d. 2.4,5,8,10.
e. 2.4.5.7.9.

Answers

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.
