What is RNA?

Full form of RNA has ribonucleic acid and it has a nucleic acid which has been found in almost all cells that are living and RNA has mostly similar to DNA but there is one difference between RNA and DNA and the difference is that RNA has single stranded but DNA is double stranded.

The RNA has backbone has made up of the phosphate group which has arranged in alternating form and the sugar known as ribose other than the deoxyribose  present in DNA. There are four bases found in RNA and these are adenine, uracil, guanine, and cytosine.

The main function of mRNA is it work as imedieter between protein and DNA which is utilised by ribosome for the process of direct synthesis of protein, and the function of tRNA is to carry the accurate amino acid to the proteins synthesis site which takes place in ribosome.

Therefore, Molecule gets translated into a protein by the ribosome within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis the stitching together of amino acids to make a protein molecule.

explain the effect enzymes have on chemical reactions

Answers

Answer:

Enzymes decrease the activation energy, Enzymes increase the rate of the reaction, Enzymes provide a site where reactants can be brought together.

Enzymes are like catalysts which enhance the rate of reaction by lowering the activation energy.

All the biochemical reactions are slow because of transition state barriers. These transition state barriers are an intermediate state before the formation of products. Transition state is a high energy state and it requires a lot of energy to cross this state but we can not produce this much energy in our body. That is why an enzyme is must to catalyze any bio-chemical reaction because enzyme provides an alternate pathway which requires very low energy to proceed.

Enzymes have certain active sites wherein substrates fit in and interact with each other with the help of their functional groups and interaction of these substrates subsequently leads to product formation.

structurally, atp is most like which type of molecule?

Answers

Answer:

ATP full name is Adenisin Triphosphate, therefor the molecule would look similar to adensisine, the nucleotide.

Explanation:

Structurally, ATP is most like RNA type of molecule. Therefore, option (A) is correct.

ATP and RNA are nucleic acids, macromolecules made of nucleotides. Cells employ high-energy ATP for energy. Adenosine has three phosphate groups.

RNA also helps gene expression and protein synthesis. Nucleotides comprise ribose sugar, phosphate, and one of four nitrogenous bases (adenine, guanine, cytosine, or uracil).

Ribose sugar and phosphate groups make ATP and RNA structurally similar. Unlike RNA, ATP possesses a high-energy phosphate bond. This additional phosphate bond makes ATP a good energy currency for cells. Therefore, option (A) is correct.

Plants release oxygen as a by-product of photosynthesis. Draw a conclusion about other life forms in the lake, based on this data. A) All of the life forms in the lake can be found within the top 10 feet of water. B) As you increase in depth of water, plant density decreases while fish density increases. C) Organisms in the lake rely on dissolved oxygen to survive. The lower the dissolved oxygen, the lower the survival rate. D) Plant survival is related to the amount of light (depth) but animal survival is related to the amount of oxygen available. The lower the amount of dissolved oxygen, the less animal life present in the lake.

Answers

Algae growth produces a high concentration of oxygen on the surface, which decreases with depth. The less oxygen available in deeper strata, the fewer surviving forms of life. The correct option is C.

According to this table,

On the surface, there is a higher amount of algae, and hence, more dissolved oxygen. As it gets deeper, algae amount decreases as well as dissolved oxygen.

If oxygen decreases with depth, it suggests that plants -oxygen producers- lack, probably due to the lack of sunlight reaching the bottom.

Other forms of life

Algae growth on the surface blocks the pass of light to the deeper strata.

The lack of light in deeper strata affects plants' growth.

If there are no plants in deeper areas, there is no dissolved oxygen.

Since animals need oxygen, they probably can not survive in deep regions.

With no oxygen, the bottom turns into an anaerobic environment, in which anaerobic bacteria can survive.

These conditions can be related to eutrophication.

Eutrophication is a biological process produced in water by an oversupply of nutrients or organic matter.

This oversupply, mainly of nitrogen or phosphorous, favors phytoplankton multiplication, especially cyanobacteria.

Cyanobacteria overgrowth leads to an enhance in primary productivity and reduces the pass of radiation to deeper strata. This fact affects biota in deeper zones.  

Gradually sedimentation begins, caused by the death of some vegetable organisms that sink in the bottom.

These sediments suffer decomposition in the absence of oxygen. Anaerobic bacteria act and produce fermentation.

Phytoplankton overgrowth on the surface and fermentation process in the bottom, originate toxic compounds that can damage the animals in the water body.

Animals die, creating more sediments in the bottom where there are anaerobic conditions.

The continued increase in decomposition and fermentation produces a bad smell and toxicity.  

The result of eutrophication is the stratification of the water mass:

First superficial layer, the overgrowth of blue-green algae, produces toxins and interrupts the pass of light to deeper areas. The surface then becomes warmer.

The second layer might have oxygen available for the animals.

In the third layer, there is no oxygen, so life is impossible for animals or plants.

In the fourth layer, there are animals and plant remains in the process of sedimentation.

At the bottom, there are organic matter and anaerobic bacteria in charge of decomposition and fermentation, through which they produce toxic gases and smell.

Options:  

A) All of the life forms in the lake can be found within the top 10 feet of water. FALSE. Depends on the conditions and the species.

B) As you increase in depth of water, plant density decreases while fish density increases. FALSE. Plant and animals density decrease, as available oxygen decrease.

C) Organisms in the lake rely on dissolved oxygen to survive. The lower the dissolved oxygen, the lower the survival rate. TRUE.

D) Plant survival is related to the amount of light (depth) but animal survival is related to the amount of oxygen available. The lower the amount of dissolved oxygen, the less animal life is present in the lake. FALSE. Light does not reach the bottom, so there are no plants there. Plants also depend on oxygen, not only animals.

What characteristic of water causes it to display adhesion cohesion high specific heat capillary action

Answers

I think the answer should be the fact that water is a polar molecule.

This means it will attract other molecules which are polar (adhesion), including itself (cohesion).

I'm not sure about the last part of the question (high specific heat capillary action, the wording is a little confusing), but I think the reason why water has a high specific heat is the hydrogen bonds. Hydrogen bonding is the strongest kind of bond you can have in a molecule, so it would be harder to break those bonds, even with high heat.

Which statement about the balanced equations for nuclear and chemical changes is correct? (1 point) Both are balanced according to the total mass before and after the change. A chemical equation is balanced according to mass number. A nuclear equation is balanced according to the total mass before and after the change. Both are balanced according to the mass number of each element before and after the change. A nuclear equation is balanced according to mass number. A chemical equation is balanced according to the total mass before and after the change.

Answers

Both nuclear and chemical equations are balanced according to the total mass before and after the change.

In every equation or reaction, the total mass of the reactants must be equal to the total mass of the products. In other words, all reactions - be they chemical or nuclear - must obey the law of conservation of mass.

The law of conservation of mass states that mass can neither be created nor destroyed, but can be converted from one form to another during a reaction.

Thus, in order to balance reactions involving chemical or nuclear reactants, the total mass before the reaction must be equal to the total mass after the reaction.

Eukaryotic cells are more complex than prokaryotes, and the DNA is linear and found within a nucleus. Eukaryotic cells boast their own personal "power plants", called mitochondria.The complex eukaryotic cell ushered in a whole new era for life on Earth, because these cells evolved into multicellular organisms.

Explanation:

Answer:

The ability to maintain different environments inside a single cell allows eukaryotic cells to carry out complex metabolic reactions that prokaryotes cannot. In fact, it's a big part of the reason why eukaryotic cells can grow to be many times larger than prokaryotic ones.
