what are the biological structures

Answers

Answer 1

Answer:Biological structures are able to adapt their growth to external mechanical stimuli and impacts. For example, when plants are under external loads, such as wind force and self-weight, the overloaded zones are reinforced by local growth acceleration and the unloaded zones stop growing or even shrink. Such phenomena are recorded in the annual rings of trees. Through his observation of the stems of spruce, K. Metzger, a German forester and author, realized that the final goal of the adaptive growth exhibited by biological structures over time is to achieve uniform stress distribution within them. He published his discovery in 1893.12 A team of scientists at Karlsruhe Research Centre adopted Metzger's observations and developed them to one single design rule: the axiom of uniform stress. The methods derived from this rule are simple and brutally successful like nature itself. An excellent account of the uniform-stress axiom and the optimization methods derived from it is given by Claus Mattheck in his book ‘Design in Nature’.13 The present study utilizes one of these methods, stress-induced material transformation (SMT), to optimize the cavity shape of dental restorations.

Answer 2

Answer:

Structural biology is a branch of molecular biology, biochemistry, and biophysics concerned with the molecular structure of biological macromolecules (especially proteins, made up of amino acids, RNA or DNA, made up of nucleotides, and membranes, made up of lipids), how they acquire the structures they have, and how alterations in their structures affect their function.

If the entire mRNA sequence for a polypeptide was AUGUACUCGCGACCGUAA, how many amino acids does the polypeptide have

Answers

Answer:

5 amino acids

Explanation:

The process of translation involves synthesizing a sequence of amino acids from a mRNA template. The mRNA molecule is read in a group of three nucleotides called CODONS. A codon specifies or codes for an amino acid.

In the question, a mRNA sequence was given as follows: AUGUACUCGCGACCGUAA. From this sequence comprising of 6 codons, 5 possible amino acids will be contained in the polypeptide encoded by this mRNA molecule as the last codon (UAA) is a STOP codon. The following are the codons in the mRNA sequence and their respective amino acids:

*AUG- methionine (met)

*UAC - tyrosine (Tyr)

*UCG - Serine (Ser)

*CGA - Arginine (Arg)

*CCG - Proline (Pro)

Why do you think during the evolutionary process there was a correlation between brain size increasing while cecum size decreased in the omnivores?
How does insect respiration differ from that of vertebrate respiration? How do they manage to respire?

Answers

Answer:

Brain size increase due to find out improved quality diets whereas cecum size decrease due to reduction of its need.

Explanation:

Brain size increased due to the need to increase the mental capacity of an organism in order to explore the environment for the survival such as search for improved quality diet and the cecum size decreased because omnivorous diet improved due to the reduction of its need as a component of the digestive system. Insects have different respiration system as compared to vertebrates because vertebrates uses lungs for respiration whereas the insects uses tracheal tubes for the absorption of oxygen and removal of carbondioxide gas.

in order for polar compounds to enter into the hydrophobic space of phospholipid tails, it would need to break the many ___ bonds

Answers

Answer:

In order for polar compounds to enter into the hydrophobic space of phospholipid tails, it would need to break the many hydrogen bonds

Explanation:

In the presence of water, the hydrophobic tails tend to interact with each other, creating a hydrophobic space from which water is excluded and in which other hydrophobic molecules can be trapped, while the polar head interacts with water, and is solvated, preserving the hydrophobic part from all contact with water. For a hydrogen bridge to form, a molecule that has hydrogen attached to an atom of high electronegativity and another molecule that has another electronegative atom with high electron density (that is, a negative partial charge) is required. Water molecules in the bulk of the body of water maintain multiple interactions with other molecules through an extensive network of hydrogen bridges, so for polar compounds to enter, it would be necessary to break many of these bonds.

Na + Cl2 --> NaCl if you were given 15 grams of sodium (with excess chlorine) and asked to determine the amount of NaCl that would be produced (in grams), how would you go about doing it. Be as specific as possible and include numerical values when necessary.

Answers

Answer:

The correct answer is - 38.15 gm of NaCl.

Explanation:

Write the balanced equation for this reaction of sodium (Na) and chlorine (Cl₂) to produce sodium chloride (NaCl):

2Na + Cl₂ —> 2NaCl

the mass of Na and the mass of NaCl :

Molar mass of Na = 23 g/mol

In the balanced equation = 2 × 23 = 46 g

Molar mass of NaCl = 23 + 35.5

= 58.5 g/mol

similarly in balanced equation = 2 × 58.5 = 117 g

From the balanced equation above,

46 g of Na reacted to produce 117 g of NaCl.

By converting it to 15 grams of Na.

Therefore,15 g of Na will react to produce = (15 × 117)/46 = 38.15 g of NaCl.

Thus, 38.15 g of Na

Solutions having osmotic pressures less than those of body fluids are called Group of answer choices hyposmotic. hyperosmotic. magnosmotic. neosmotic. isosmotic. PreviousNext

Answers

Answer:

hyposmotic

Explanation:

Body fluids are in contact with cells. Cells are surrounded by a semi-permeable membrane, through which can pass certain solutes. If the concentration inside the cells is different from the body fluids, the water molecules will move from the more concentrated compartment to the less concentrated one. This process is called osmosis.

If the body fluids are more concentrated than cells, the solution is called hypertonic (body fluids are hyperosmic). If the body fluids are less concentrated than the cells, the solution is called hypotonic (body fluids are hyposmotic).

The statement that there must be a preexisting cell in order for a new cell to form is known as cell

Answers

Answer:

cells duplicate so when there is no cell it cant make any

Explanation:

The statement that there must be a preexisting cell in order for a new cell to form is known as cell theory.

What is cell theory?

The scientific idea that cells make up living organisms, that they are the fundamental structural and organizational unit of all species.

They all originate from previously existing cells is known as cell theory. It was first proposed in the middle of the nineteenth century.

Because cells are the building blocks of all life, cell theory is essential for our understanding of biology.

We can have single-celled organisms like yeasts and bacteria. All living things grow and develop on the basis of cell division, or the division of a cell from one to two to four.

A vital process for life is mitosis. A cell divides into two identical daughter cells after duplicating all of its components, including its chromosomes.

Thus, the statement "cell arises from pre-existing cells" comes from cell theory.

Humus is made of Earthworms, nutrients and bacteria. So, the correct options are A, B and C.

What is Humus?

Humus is the soil's black organic material that results from the breakdown of plant and animal debris. It is a type of organic material for soil. It has a lot of nutrients and keeps the soil moist. The Latin word for "earth" or "ground" is humus.

Humus is described as a dark organic substance that develops in soil as a result of plant and animal debris decomposing. It is organic and dark in colour because carbon has accumulated there. It contains elements that are crucial to maintaining healthy soil. Earthworms, nutrients, and microbes make up humus.

Because humus is a feature of loamy soils, the high concentration of nutrients in the soil is caused by humus. Humus reduces a substance's porosity by obstructing the pores that permit the passage of water and air.

Therefore, the correct options are A, B and C.

Part D :
How might someone dispute the results of this investigation? How might you counter the argument?

Answers

Answer:

It could be argued that there is a separate force acting upon the investigation. Or that the room is invalidating the results for some reason. Or that an error was made in measurement.

There are a thousand and one ways to try to dispute an investigation like this. However, for every argument that can oppose it, a counterargument can easily be made.

For instance, controlling the variables invalidates about 90% of any possible claims to the contrary. The majority of arguments would stem from the fact that it is nearly impossible to completely prove something in fear of external factors. The solution? Control the external factors.

So, in conclusion, a person could dispute the results of the investigation by claiming that something invisible like magnetics could not possibly be proven to exist, because there are all sorts of things that could be influencing the investigation. The way to counter the argument would be to prove yourself that the environment is controlled, and that nothing could be influencing the investigation.

G. Hodges, Esq., Frankfort, Ky.My Dear Sir: You ask me to put in writing the substance of what I verbally stated the other day, in your presence, to Governor Bramlette and Senator Dixon. It was about as follows: I am naturally anti-slavery. If slavery is not wrong nothing is wrong. I cannot remember when I did not so think and feel; and yet I have never understood that the Presidency conferred upon me an unrestricted right to act officially in this judgment and feeling. It was in the oath I took that I would to the best of my ability preserve, protect and defend the Constitution of the United States. I could not take the office without taking the oath. Nor was it in my view that I might take the oath to get power, and break the oath in using the power. I understood, too, that in ordinary civil administration this oath even forbade me to practically indulge my primary abstract judgment on the moral question of slavery. I had publicly declared this many times and in many ways; and I aver that, to this day I have done no official act in mere deference to my abstract judgment and feeling on slavery. I did understand, however, that my oath to preserve the Constitution to the best of my ability imposed upon me the duty of preserving, by every indispensable means, that government, that nation, of which that Constitution was the organic law. Was it possible to lose the nation, and yet preserve the Constitution? By general law, life and limb must be protected; yet often a limb must be amputated to save a life, but a life is never wisely given to save a limb. I felt that measures, otherwise unconstitutional, might become lawful by becoming indispensable to the preservation of the Constitution through the preservation of the nation. Right or wrong, I assumed this ground, and now avow it. I could not feel that to the best of my ability I had even tried to preserve the Constitution, if, to save slavery, or any minor matter, I should permit the wreck of government, country, and Constitution altogether. When, early in the war, General Fremont attempted military emancipation, I forbade it, because I did not then think it an indispensable necessity. When, a little later, General Cameron, then Secretary of War, suggested the arming of the blacks, I objected, because I did not yet think it an indispensable necessity. When, still later, General Hunter attempted military emancipation, I forbade it, because I did not yet think the indispensable necessity had come. When, in March and May and July, 1862, I made earnest and successive appeals to the Border States to favor compensated emancipation, I believed the indispensable necessity for military emancipation and arming the blacks would come, unless averted by that measure. They declined the proposition; and I was, in my best judgment, driven to the alternative of either surrendering the Union, and with it the Constitution, or of laying strong hand upon the colored element. I chose the latter. In choosing it, I hoped for greater gain than loss; but of this I was not entirely confident...Yours truly,A. LincolnUse context to determine the meaning of the words in bold.
