which substance is an inorganic molecule?
A) starch B) DNA C) water D) fat

Answer:

The correct answer is the layer on the bottom.

Explanation:

The formation of the sedimentary rock takes place by the deposition of sediments at the bottom of the water bodies like seas and oceans. The newer deposits of soil that comes via inland inlets, get settled over the previously deposited sediments. The sediments are brought in spontaneously unless and until they become sufficiently big in order to impart intense pressure on the layers underneath and thus results in the formation of rocks.

Answer:

Chlorofluorocarbon ( CFC )

Explanation:

Chlorofluorocarbon ( CFC ) is halogenated paraffin hydrocarbon that consists of carbon, hydrogen, fluorine and chlorine. It is derivative of methane, ethane and propane. It was used as refrigerant and propellant in aerosol cans. It triggers ozone depletion hence its manufacture has been stopped under Montreal Protocol and it has been replaced with other hydro fluorocarbons.

UV light on striking a CFC molecule in upper atmosphere, breaks the carbon chlorine bond which produces a chlorine atom. This chlorine atom reacts with an ozone molecule and destroys it. Hence, CFC damage the ozone layer of the Earth.

Vitamin B12 is not harmful. Food or high-dose supplements don't create adverse effects or high levels. Therefore, its false.

Cobalamin, also referred to as vitamin B12, is a water-soluble vitamin essential for metabolism.  Animals need it because they use it as a cofactor in the creation of DNA and in the metabolism of fatty acids and amino acids. Additionally, it plays a significant role in the growth and operation of brain and nerve cells. The protein in the foods we eat forms a bond with vitamin B12. Vitamin B12 becomes free vitamin in the stomach when enzymes and hydrochloric acid break its bond.

The amounts of vitamin B12 do not build up to hazardous levels. Whether you acquire it through food or by taking supplements at high doses, consuming a lot of it won't have any negative effects or result in high levels in your system.

Answer: transfer of heat between two objects that are touching. Conduction involves contact. My son just took this quiz, he was correct with his answer.

The correct answer is option A,  Plants take in carbon dioxide and produce glucose-animals consume plants-animals break down glucose and release carbon dioxide.

Reason -

The carbon cycle comprises of following stages

a) Release of carbon dioxide in the atmosphere – carbon is released in the form of CO2 as a result of  exhalation process during respiration of all living species or by burning of fuels or decomposition of dead organic matter etc.

b) Carbon uptake by plants – Plants take in CO2 to produce glucose and oxygen during the process of photosynthesis.  

c) Usage of carbon product produced by plants – All animals or human beings consume the plant to take in the carbon entrapped by the plant in the form of glucose  

d) Release of carbon by animals/living species – Again after consuming plants, the living beings including animals exhale out CO2 by respiration, or microorganisms feed on the dead remains to release carbon in the soil

This process continues in a cyclical chain manner again and again.

The equation that represents fertilization is haploid + haploid = diploid

The correct option is (c).

Fertilization is a crucial process in sexual reproduction where two haploid gametes, one from each parent, combine to form a diploid zygote. The fusion of these gametes results in the formation of a new individual with a complete set of chromosomes, one set from each parent.

In the equation "haploid + haploid = diploid," both sides of the equation represent the genetic material involved in fertilization. The term "haploid" refers to cells containing one set of chromosomes, representing either the sperm or egg cell. During fertilization, these two haploid gametes unite to form a diploid zygote, which contains two complete sets of chromosomes, one set from each parent. Therefore, the equation accurately represents the genetic process of fertilization.

Option a, "haploid + diploid = diploid," does not accurately represent fertilization because it implies that one of the gametes involved is already diploid, which is not the case in typical fertilization.

Option b, "diploid + haploid = haploid," also does not represent fertilization accurately. This equation suggests the production of a haploid offspring, which is not the result of fertilization.

Option d, "diploid + diploid = diploid," does not reflect the process of fertilization either. This equation implies the fusion of two diploid cells, which does not occur during normal fertilization.

In summary, option c, "haploid + haploid = diploid," best represents the process of fertilization, accurately depicting the fusion of two haploid gametes to form a diploid zygote, which is the fundamental event in sexual reproduction.

In this respiration, an organic molecule such asglucose is the electron donor and oxygen is the electron acceptor.Oxygen has a very high affinity for electrons, so a great deal ofenergy is released during aerobic respiration. Aerobic respirationis the primary mode of energy metabolism in animals.

Fermentation (common form of energy metabolism) Inthis, organic molecules serve as both electron donors and electronacceptors. Electrons are just moved from one carbon to another ofthe same molecule. Fermentation releases much less energy than respiration, since organic molecules have a lower affinityfor electrons than does oxygen.

Anaerobic conditions, glucose is oxidized to pyruvic acidvia glycolysis ,generating ATP and NADH. The pyruvic acid thenserves as the electron acceptor, producing CO2 andethanol as it re-oxidizes NADH back to NAD. Only two ATP are formedduring fermentation.

Under aerobic conditions, the pyruvic acid movesinto the mitochondria. In the mitochondria, the pyruvic acid isoxidized to acetyl CoA, which enters the tricarboxylic acid cycle(TCA cycle) where it is oxidized to CO2.

Three CO2 are produced for every pyruvate, or sixfor every glucose entering glycolysis. The electrons removed frompyruvic acid during its oxidation to CO2 aretransferred to NAD, reducing it to NADH. The NADH donates itselectrons to the electron transport system, which passes them on toO2 .

Many ATP are formed at the electron transport system.

Yeast obtains 36 moles of ATP per mole of glucose whenrespiring, compared with only two moles of ATP per mole of glucosein fermentation.

.Both processes usually startwith the same first step, glycolysis, but follow differentsubsequent pathways.

Duringfermentation,

1. Releases energy from sugars or other organic molecules,such as amino acids, organic acids, purines,pyrimidines.

Does not require oxygen (but sometimes can occur inits presence);

2. Does not require use of the Krebs cycle or anelectron transport chain .

3. Uses an organic molecule as the final electronacceptor; That produces only small amounts of ATP (only one or twoATP molecules for each molecule of starting material) because muchof the original energy in glucose remains in the chemical bonds ofthe organic end-products, such as lactic acid or ethanol. Duringfermentation, electrons are transferred (along with protons) fromreduced coenzymes (NADH, NADPH) to pyruvic acid or itsderivatives.

Final answer:

Aerobic respiration greatly surpasses fermentation in efficiency, yielding up to 38 ATP per glucose molecule compared to only 2 ATP made through fermentation. Fermentation occurs without oxygen and utilizes organic compounds as the final electron acceptors, limiting its energy production.

Explanation:

Comparing aerobic respiration and fermentation in terms of energy efficiency from glucose illustrates a significant difference in ATP yield. Aerobic respiration is a highly efficient process that can yield up to 38 ATP molecules from a single glucose molecule. This process includes glycolysis, the Krebs cycle, and oxidative phosphorylation, utilizing oxygen as the final electron acceptor. On the other hand, fermentation, which can occur in the absence of oxygen, yields a mere 2 ATP molecules per glucose. Fermentation begins with glycolysis; however, it diverges by using organic compounds as the final electron acceptor, lacking the further ATP yield seen in aerobic processes due to the absence of the Krebs cycle and oxidative phosphorylation.

In essence, the efficiency difference is stark: aerobic respiration provides a higher yield of ATP, making it a preferred method for energy production in the presence of oxygen. In contrast, fermentation is a quicker, though much less efficient, process adopted in anaerobic conditions or scenarios where rapid energy production is required, such as in muscle cells during intense exercise.

Tissue-level organization first appears in phylum Cnidaria, which includes Cnidarians with organized tissues and specialized cnidocytes, unlike the simpler phylum Porifera.

Tissue-level organization is first seen in the phylum Cnidaria. Organisms in phylum Porifera, like sponges, do not possess true tissues, but rather have a simple organization comprising different cell types that together perform necessary functions.

In contrast, Cnidarians such as jellyfish, corals, and sea anemones, have developed organized tissues from two embryonic cell layers, the ectoderm and the endoderm, and have specialized cells called cnidocytes used for stinging and capturing prey.
