Answer:
Mechanism of formation of proteins:
The Protein Synthesis Mechanism. Protein synthesis consists of a peptide chain employing tNS as a blueprint for the precise sequence to supplement amino acids and mRNA.
One of the first stages in the protein synthesis system is transcription. The additional mRNA strand shall be produced in accordance with DNA Base Nitrogen Code. The polymerase enzyme of RNA blinds to one of the double helix RNA molecules
Explanation:
During the synthesis, transcription, and translation of proteins, two processes occur. DNA is a blueprint for making the messenger RNA when transcribed (mRNA). The nucleus of eukaryotic cells is transcribed. Translation takes place when the mRNA exits the nucleus and is placed into the ribosome in eukaryotic cell cytoplasms. The genetic code in mRNA is read and utilized for protein production during translation. Translation has three steps: starting, elongating, and ending. Beginning: the ribosome binds the mRNA and the tRNA. Extension: amino acids given to the developing protein chain one-time. The tRNA connects the anticodon with the mRNA codon and transports the appropriate amino acid each time peptidyl transmission establishes peptide bonds among amino acids.
Termination: when a stop codon is present (UGA, UAG, UAA) the tRNA detects the stop codon and releases the translation and ends.
Physical Properties of Proteins:
Taste and ColorProteins are normally colorless and tasteless. They are uniform and crystalline.
Shape and dimensionsThe proteins range in form from simple crystalloids to lengthy fibrillary structures. Two different form patterns
Were acknowledged:
A. Globular protein – Sphere shaped and most commonly occurs in plants, e.g., seeds and leaf cells. These are packs that makeup protein chains fold and crumble, such as pepsin, destine, insulin, ribonuclease, etc.
B. Fibrillary protein- Thread-like or ellipsoidal, usually in animal muscles. These proteins have been used in most of the protein structural research. For example, myosin, fibrinogen, etc.
Weight of moleculesThe proteins usually contain huge molecular weights from 5 to 103 to 1 to 106. It may be mentioned that molecular weight values of several proteins are nearly 35,000 and 70,000 or several.
Nature of ColloidsProteins are very slow to diffuse and hence may produce extensive light dispersion in solution, leading to apparent turbidity, because of their huge size (Tyndall effect).
DenaturationDenaturation refers to alterations in protein characteristics. It's the lack of organic activity, in other words. In many cases, denatured protein molécules tend to form big aggregates and precipitate solutions, and coagulation is followed by the process of denaturation.
Nature of AmphoteryProtein is amphoteric, like amino acids, i.e. it acts as both acids and alkalis. The movement of the latter in an electrical field depends on the net cargo of the molecule. The net load depends on the pH value. Every protein has an isoelectric point (pl) fixed value at which it moves in an electric field.
Capacity Ion Binding
Proteins can generate salts based on their netload, both with cations and anions.
SolubilityProtein solubility is dependent on pH. At an isoelectric point, solubility is lowest, and with rising acidity or alkalinity increases. This is because when protein molecules exist as cations or anions there are large repulsive interactions between ions, as all molecules have the same sign at an excessive charge. They are therefore more soluble than isoelectric.
Activity OpticalThe polarised light plane is turned to the left by all protein solutions, i.e. levoratotory.

The history of life has been punctuated by several mass extinctions. For example, the impact of a meteorite may have wiped out most of the dinosaurs and many forms of marine life at the end of the Cretaceous period. Fossils indicate that plants were less severely affected by this mass extinction. What adaptations may have enabled plants to withstand this disaster better than animals
Answer:
Due to dormancy.
Explanation:
Plants have an advantage in surviving mass extinction because Plant seeds can remain dormant for many years in the soil without damaging and comes out from the soil when the conditions of the external environment become suitable. Plants can remain in dormant condition for a large period of time while on the other hand, animals have no such type of advantage so that's why plants survive mass extinction.
What would be most likely to happen if some of the proteins Ik one of the photo systems were to change shape due to a drop in cell pH?
A. A decrease in the formation of NADPH
B. An increase in the formation of NADP+
C. A decrease in chlorophyll production
D. An increase in sugar production
Answer:
Option A
Explanation:
If some proteins in one of the photosystems undergo change in their shape due to a drop in pH of cell, they will not perform their activity. Due to this, there will be a decrease in the formation of NADPH ( that is less reduction of NADP due to blockage in the transport of electron).quá trình nhận thức là gì và kết hôn đồng tính là gì

In an experiment, a small dialysis bag is filled with a 20% salt solution. It is placed in a
beaker filled with a 40% salt solution. Assuming that water can pass through the
small pores of the dialysis bag, whereas the large salt molecules cannot, what will
happen to the size of the dialysis bag?
Answer:
The bag will get smaller
Explanation:
Osmosis can be defined as the process of diffusion or movement of water molecules across a semipermeable membrane from an area of higher concentration of water (i.e., lower concentration solution) to a lower concentration of water. For example, in cells, there are specialized pores called 'aquaporins' which are membrane proteins that form channels to transport water molecules by facilitated diffusion. In this case, the outside of the bag has a higher salt concentration than inside, thereby water molecules will move by facilitated diffusion through pores from inside to outside the bag.

Please read the article Why Cats Have Nine Lives by Jared Diamond. Our analysis did not attempt to
answer the question of "Why" cats survive they way they do from different heights. What are some of
the assumptions the author makes that he uses in an attempt to answer this new question?
The author assumes that the question can be answered by applying principles of anatomy, physics and evolutionary biology. First reason he suggests is that cats are small and they have a favourable mass-surface area ratio. Next, he suggests that cats have soft tissues that absorb the shock and they land on all four limbs, dividing the shock. This is because of their body shape and its centre of gravity. He says that felines have this kind of body structure (that canines lack) because years of falling from trees etc. has evolved their body in this way.
The following assumptions that stem from the Straightforward theory were used by the author to explain why cats have nine lives. They include;
The larger mass of bigger animals causes more impact stress on landing.The unique vestibular systems of the cats and the gyroscopic turns they make that have their four feet pointing downwards before landing.The cats reach terminal velocity faster and extend their limbs reflexly to absorb the shock from the fall.The dissipation of the impact force due to their flexed limbs.Lastly, their evolutionary history that has seen them falling from trees frequently over the years.In his article, Jared Diamond profers several reasons why he believes that cats tend to suffer fewer injuries and fatalities after falling from different heights.
He believes that their mass which is lower in comparison to humans makes it possible for them to not suffer much impact force on landing.
The gyroscopic turns they make before landing makes it easier for them to land on their four feet thus suffering fewer injuries to the arms.
Their evolutionary history is another factor. Over the years, they have adapted so well to falling from heights.

Which of the following is considered a Time/Temperature control for safety (TCS) food?
Eutrophication occurs when excess nutrients are supplied to a region, leading to an algae bloom and ultimately ______
A. Coral bleaching
B. Ocean deoxygenation
C. Ocean acidification
D. Overfishing
Answer:
The correct answer is - B. Ocean deoxygenation.
Explanation:
Eutrophication is the process in which a water body gets excessively rich in nutrients that leads to the algal growth or plankton growth in this region and covers the complete surface or most of the water body.
Due to this algal and plankton growth, there is a significant decrease in the concentration of the dissolved oxygen in water bodies that result in the incapability of supporting the lives found in it. The primary and main reason for this deoxygenation is eutrophication. Ocean deoxygenation is the reduction of the oxygen concentration of the oceans.

In a certain breed of dog, the alleles B and b determine black and brown coats respectively. However, the allele Q of a gene on a separate chromosome is epistatic to the B and b color alleles resulting in a gray coat (q has no effect on color). If animals of genotype B/b ; Q/q are intercrossed, what phenotypic ratio is expected in the progeny
Answer:
12 gray , 3 black, 1 brown
Explanation:
If Q allele of a gene on a separate chromosomes is epistatic to the B (black) and b (brown) color alleles, in cross between two animals with genotypes BbQq produces 12 gray coat color, 3 black coat color and 1 brown coat color animals.
BbQq x BbQq
Gray coat Gray coat
BQ Bq bQ bq
BQ BBQQ(gray) BBQq(gray) BbQQ(gray) BbQq(gray)
Bq BBQq(gray) BBqq(Black) BbQq(gray) Bbqq(Black)
bQ BbQQ(gray) BbQq(gray) bbQQ(gray) bbQq(gray)
bq BbQq(Gray) Bbqq(Black) bbQq(gray) bbqq(brown)
So the phenotypic ratio is Gray : Black : Brown
