What is a vein in rock?

Answers

Answer:

Vein, in geology, ore body that is disseminated within definite boundaries in unwanted rock or minerals (gangue). The term, as used by geologists, is nearly synonymous with the term lode, as used by miners. There are two distinct types: fissure veins and ladder veins.

Explanation:

Material deposits known as geological veins are created when an existing rock fracture is filled with a new mineral.

How rock veins are formed?

   

They are fascinating to planetary scientists because they frequently reveal information about historical water flow. For instance, a lot of rocks have natural pores.

A vein in geology is a distinctive sheet-like body of mineral crystals embedded into a rock. When precipitation occurs, mineral components that are transported by an aqueous solution within the rock mass are deposited as veins.  

Therefore, it is thought that aqueous solutions carrying different elements migrate through rock fissures and deposit their load onto the fissure walls when vein deposits occur, rising water that is hot.

Which process plays an important role in the cycling of both carbon and nitrogen? photosynthesis transpiration decomposition respiration

Answers

Answer: C

Explanation:

Decomposition plays a major process to cycle the carbon and nitrogen due to dead matter, hence option c is correct.

What is the cycling of carbon and nitrogen?

The biogeochemical cycles of carbon and nitrogen are all in plants and animals when dies bacteria decompose it and release nitrogen and carbon into the soil.

They depict how the elements travel through the Earth's life and nonliving constituents. The elements of life—carbon, and nitrogen pass through living things and nonliving things alike without ever being consumed.

Nitrification is the process by which bacteria convert ammonium into nitrates. Then, the plants may take up nitrates. It is through assimilation that plants obtain nitrogen, roots take up nitrates from the soil.

Therefore decomposition is the main process for cycling of both carbon and nitrogen, hence option c is correct.

Answers

Answer:

1. Muscles function in movement of the head, neck, and limbs, as well as propulsion of the contents through the digestive tract.

2. Muscles function in stability by preventing unwanted movement, as in maintaining posture.

3. Using sphincters, or valves, muscles control the passage of contents from one body cavity or lumen to another.

4. Since muscle contraction requires energy to do work, movement muscles help maintain our body heat.

5. By absorbing a large share of one's glucose, muscles play an important role in blood sugar control.

Explanation:

Muscles have different functions in the body. They allow our head, neck and limbs to move, and also have an important role in the propulsion of contents through the digestive track.

Muscles are soft tissues that also have a role in stability by maintaining posture and help the passage of contents from different cavities by using sphincters.

Their main source of energy is glucose in the body. By using this energy, muscles help to maintain our bodies temperature and blood sugar control.

Two genes interact to produce various phenotypic ratios among F2 progeny of a dihybrid cross. Design a different pathway explaining each of the F2 ratios below, using hypothetical genes R and T and assuming that the dominant allele at each locus catalyzes a different reaction or performs an action leading to pigment production.

O Fertilizers decrease the amount of nitrogen fixed by organisms living in the ecosystem.

O Fertilizers kill off important nitrogen fixing bacteria.

Fertilizers decrease the amount of fixed nitrogen available in the ecosystem.

Answers

Answer:

It's C

Explanation:

Hope this helped :)))

The fertilizers show a significant impact on the nitrogen cycle as the fertilizers kill off the important nitrogen fixing bacteria which are present in the soil. Thus, the correct option is C.

What is Nitrogen cycle?

Nitrogen Cycle is a biogeochemical process through which the nitrogen present in the environment is converted into many different forms, consecutively passing from the atmosphere to the soil to the living organisms and back into the atmosphere after decomposition. It involves several processes including the nitrogen fixation, nitrification, denitrification, decay and putrefaction of the nitrogen compounds.

Intensive fertilization of the agricultural soils of normal soil can increase the rates at which nitrogen in the form of ammonia is volatilized in the environment and lost to the air. It can also speed the microbial breakdown of ammonium and nitrates in the soil which results into enhancing the release of nitrous oxide. In addition to this, excessive use of fertilizers also kills the nitrogen fixing bacteria present in the soil.

Therefore, the correct option is C.

Digestion of an unlabeled carbohydrate results in increased amounts of the monosaccharides glucose and galactose. Which is most likely to be the original, unlabeled carbohydrate?

Answers

Answer:

lactose  

Explanation:

Lactose is a disaccharide sugar made up of glucose and galactose monosaccharide subunits. In lactose, galactose and glucose molecules form a covalent glycosidic bond denoted as an (β-1→4) glycosidic bond. Lactase is an enzyme that hydrolyzes lactose into glucose and galactose, which can be then absorbed into the bloodstream by the cells lining the small intestine. In an alkaline solution, lactose may also isomerize to generate a mixture of lactulose (20-30%) and lactose (70-80%).

Some individuals can develop kidney failure after consuming fava beans. What is the biochemical rationale for this observation?A. A deficiency of glucose-6-phosphatase that resulted in failure to synthesize essential red cell membrane proteins.B. A deficiency of glucose-6-phosphate dehydrogenase that resulted in failure to maintain glutathione in a state that prevents destructive lysis of the red blood cell.C. A deficiency of transketolase that resulted in the failure to provide ribose for the DNA and RNA needed to repair red cells.D. A deficiency of transaldolase that resulted in the failure to maintain glycolysis in the red cells. E. A deficiency of sedoheptulose that resulted in the failure to maintain the integrity of the red cells.

Answers

The correct answer to the question is option B

A deficiency of glucose-6-phosphate dehydrogenase that resulted in failure to maintain glutathione in a state that prevents destructive lysis of the red blood cell.

The deficiency of Glucose 6 phosphate dehydrogenase is a genetic disorder,when certain foods are consumed,the deficiency symptom to the enzyme is triggered and one of such food is Fava beans.

in Fava beans, Vicine is found, and this Vicine is an alkaloid glycoside.

Vicine is an oxidant,and it is toxic by causing disease favisim in individuals.The individual being affected are the ones that have hereditary loss of the Glucose 6 phosphate dehydrogenase enzyme.

But favisim only occurs when Fava beans is ingested fresh, that is without cooking it.

Following this,there is the development of acute intravascular hemolysis within 4-24hours after the ingestion of the Fava beans,there might also be a fall in the hemoglobin content of the blood and this may result in fatal condition.

But in cases that are acute, that is case of hemolysis, blood transfusion is vital and also in the case is kidney failure, dialysis must be done.

The reason why blood transfusion is very necessary is because the blood transfused may not have red blood cells that are deficient of Glucose 6 phosphate dehydrogenase,also the cells can have normal lifespan in the blood circulation of the recipient.

This Glucose 6 phosphate dehydrogenase is vital because it is a metabolic enzyme of Pentose phosphate pathway and it is also important for the metabolism of red blood cells.It also gives red blood cells protection from oxygen species that are harmful and reactive.

Option A is a metabolic disease that is

inherited which results in accumulation of glycogen and fat in liver.

Option C is as a result of deficiency in thiamine and malnutrition.

Option D is as a result of mutation in transaldolase gene.

Option E is as a result of genetic mutation.

Compare the normal allele for hemoglobin with the sickle cell allele. How does this difference affect the person’s red blood cells?

Answers

Answer:

Sickle cell anemia is an inherited condition in which there aren't enough healthy red blood cells to carry oxygen through an individual's body. The red blood cells of a healthy individual are flexible and round, and they move through blood vessels with no problem, transporting oxygen successfully. However, a person with sickle cell anemia has rigid, sticky red blood shaped like sickles or crescent moons. These cells often get stuck in small blood vessels, which can slow or block blood flow and oxygen delivery to different parts of the body.

The sickle cell anemia trait is found on a recessive allele of the hemoglobin gene, while the regular red blood cell trait is found on the dominant allele. This means that a person must have two copies of the recessive allele (one from their mother and the other from their father) to be born with this condition. People who have one dominant and one recessive allele or both dominant alleles will have healthy red blood cells.

1. Compare and contrast mitosis and meiosis. 2. What major event occurs during interphase?

Answers

Answer:

1.

contrast between mitosis and meiosis

Mitosis

- it takes place in somatic cells in multi cellular organisms in order to provide growth, however, in unicellular organisms it is reproductive division as well. is the means of reproduction in single-celled organisms. Other organisms use it for the growth of tissues (somatic cells)

- exact number of chromosome in offspring

- no recombination or crossing over

- no pairing found

- major phase: prophase, metaphase, anaphase, telophase

Meiosis

- takes place in sex cells to form gamete formation during sexual reproduction

- half of the chromosome number found in gametes of the parents thus, known as reduction division

- due to crossing over takes place recombination  found.

The pairing of chromosomes takes place

- major steps:

Meiosis 1 – prophase, Metaphase, anaphase, Telophase, and

Meiosis 2: Prophase, Metaphase, Anaphase, and Telophase

2. Interphase takes place prior to both mitosis and meiosis which is divided into 3 sub phases-G1, S and G2 phases.

The major events are as follows:

G1- RNA and protein synthesis takes place and cell grows in size

S- DNA replication takes place, Centriole duplication occurs and synthesis of histone proteins.

G2-  RNA and Protein synthesis continues.

Answer:

When ground water reaches the surface it can form lakes or rivers.

Explanation:

Groundwater in valleys is often pushed under pressure by rainwater that falls on the nearby highlands. If the water table reaches the surface, a lake, a river, or a spring is formed. A spring in desert country is surrounded by plants that take advantage of the water supply, forming an oasis. Water now coming to the surface at oases in the Sahara Desert came from rain that fell on hills near the desert during the Middle Ages--eight hundred to one thousand years ago.
