I beleive its Translation

Answer:

The correct answer will be translation.

Explanation:

Ribosomes are cell organelles present either in cytoplasm or attached to endoplasmic reticulum in protoplasm of a cell.

They are involved in the process of translation or the synthesis of protein by translating the coded information of mRNA into amino acids to form proteins. So, they are also known as translators of cell.

Protein synthesis starts during the initiation phase of translation after reading start codon (AUG). Translation terminates when ribosome reaches   any of the stop codons that is UGA, UAA, and UAG at 3'-end the synthesized polypeptide will dissociate from the ribosome.

Thus, translation will be the correct answer.

Filtration is any of various mechanical, physical or biological operations that separate solids from fluids (liquids or gases) by adding a medium through which only the fluid can pass.

The transition from fall to winter could be considered an environmental change. Which kind of change is winter?

It should be considered a short-term change because it lasts less than a year.

Environmental changes are changes or disturbances in the environment most often caused by human influences and natural ecological processes.

Answer: short-term, because it lasts less than a year

Explanation:

A short term change is a kind of environmental change which occur over a short period of time. It exerts influence over the environment and over the living beings for short time. A short term change include seasonal variation, drought, smog, pollution, flood and volcanic eruption. The effects caused by these changes can be recovered in an short time.

The transition from fall to winter could be considered as short term environmental change. This is due to the fact that it is the example of seasonal variation. The winter season remains for short term that is less than a year.

The biologists have categorized protozoans as a part of Kingdom Protista, they have attempted to sort protists in comparison to three of the other kingdoms, that is, animals, plants, and fungi. However, this has not worked as several of the protists demonstrate features from two or more of these kingdoms.  

The protozoans show considerable diversity, that is, some live as predators, some as parasites, and some others are thriving as producers. Scientists have attempted to categorize the organisms within the protists as either fungus-like, plant-like, or animal-like.  

However, close testing and genetic examination have shown that these classifications often does not imply.  

Final answer:

Algal blooms can result in dead zones due to oxygen consumption by bacteria, and the production of toxins by certain algae can cause health risks and economic losses. Responsible use of fertilizers and wetland restoration are essential measures to prevent harmful effects on the environment.

Explanation:

Negative Effects of Algal Blooms on the Environment

One negative effect of algal blooms on the environment is the creation of dead zones in aquatic ecosystems. As an algal bloom occurs and the algae subsequently die, they provide a significant amount of organic matter to deep-water bacteria, resulting in a surge of bacterial population growth. These bacteria consume large amounts of oxygen, leading to regions where animal life can scarcely survive due to oxygen depletion. This process is detrimental to aquatic life and disrupts the natural balance of the ecosystem.

Another harmful impact of algal blooms is the production of toxins by certain species of algae such as Karenia brevis, which causes red tides, and cyanobacteria. These toxins can be fatal to fish and accumulate in shellfish, posing health risks to humans who consume them and causing economic losses due to the closure of affected fisheries. In addition, the presence of cyanobacterial toxins like microcystins can lead to allergic reactions and liver damage when ingested in contaminated water.

In conclusion, although fertilizers provide benefits for crops and are not easily banned for political and economic reasons, the resultant algal blooms necessitate responsible fertilizer use, regulation, and efforts like wetland restoration to mitigate the excess nutrients entering aquatic systems.

Kidneys filter blood and expel waste through urine. Urine formation involves glomerular filtration, reabsorption, and secretion

Urine is waste. Mostly water and urea. The body removes urea, a nitrogenous waste product. Filtration, reabsorption, and secretion form urine in the kidney.

Filtration. Kidneys filter blood. Arteries feed the kidney's glomerulus. Bowman's Capsule contains the kidney's glomerulus. Filtration. High-pressure blood forces substances through small capillaries. Walls strain. Filtration.

Filtrate—water, sugar, salts, amino acids, nitrogenous wastes, and other microscopic things—enters the kidney. Cells and large blood proteins stay in arteries. Pre-urinary kidney filtrate.

Reabsorption: Filtrate enters proximal tubule. This kidney filters many chemicals. These are absorbed.

Glucose, salts, vitamins, hormones, and amino acids are restored. The filtrate may retain excess sugar or salt from the body. Because glucose cannot be reabsorbed, high-blood-glucose diabetics may pee glucose. Pre-urine is reabsorbed.

Secretion. The Loop of Henle exchanges water and salt. The distal tubule releases it following the Loop of Henle.

Excretion must be accelerated sometimes. Toxins always leave rapidly. No filtering or absorption. The blood artery secretes them into the distal tubule's almost-formed urine.

The DNA of every higher organism consists of two strands which are joined together through bonding between nitrogenous bases. We know well that the base of one strand forms hydrogen bond between the base of the other strand to hold the DNA intact. Thymine always pairs with Adenine and Guanine always pairs with Cytosine, this way an intact and normal DNA structure is formed.

However, sometimes the Ultra violet (UV) rays cause serious damage to DNA. When UV rays are absorbed by DNA, where the bases are thymine or cytosine they add energy at that point. This energy causes the formation of covalent bond between adjacent cytosine- cytosine or thymine-thymine bases of same DNA strand (Please see attached figure). This abnormal process is called the formation of Pyrimidine dimers.  

What harm they can incur to us?

Our body cells have excellent DNA proofreading mechanisms that correct the errors in DNA. But sometimes when DNA has to replicate, the dimers don’t let the DNA polymerase enzyme to correctly read DNA strand because there are abnormal structures. The enzyme incorporates wrong base, at the position of dimers for example if C-C dimer is present, adenine instead of guanine will be added at that position. This causes the presence of incorrect base in newly synthesized DNA.  

This process leads to mutation in the cells which is very common cause of increased risk of cancers nowadays.

Adjacent bases in the same strand of DNA dimerizing (forming a covalent bond) results in distortions in the normal double helix structure of DNA and can disrupt the processes of replication and transcription. This situation can lead to the induction of mutations. A common example is when ultraviolet light induces the bonding of two adjacent thymines.

When two adjacent bases in the same strand of DNA dimerize, a situation like thymine dimer can occur, a covalent linkage forms between two adjacent thymine bases on exposure to ultraviolet radiation. This type of dimer formation results in abnormal covalent bonds within the DNA strand and can produce distortions or kinks in the normal double helix structure of DNA, which in turn can interfere with normal DNA processes including replication and transcription.

While normal DNA structure largely depends on relatively weak hydrogen bonds that connect diverse base pairs (adenine with thymine, and cytocine with guanine), dimerization of two adjacent bases creates a strong covalent bond changing the DNA strand's behavior, interfering with its usual operation and causing possible mutations. An example of this strong dimerization is when ultraviolet light induces dimer formation between two adjacent pyrimidine bases, commonly two thymines, within a nucleotide strand leading potentially to frameshift or point mutations.

The arrows in the diagram represent the transfer of energy in an ecosystem. Energy enters the ecosystem through photosynthesis and flows from plants to herbivores to carnivores. The arrows can be labeled with the type of energy being transferred.

The diagram shows some of the steps in the flow of energy through an ecosystem. The arrows represent the transfer of energy. To label each arrow with the type of energy being transferred, we need to understand the flow of energy in an ecosystem. Energy enters the ecosystem through photosynthesis, which converts sunlight into chemical energy in plants. This energy is then passed from producers (plants) to herbivores (animals that eat plants) and then to carnivores (animals that eat other animals).

For example, the arrow from the sun to the plant represents the transfer of solar energy through photosynthesis. The arrow from the plant to the herbivore represents the transfer of chemical energy from the plant to the herbivore. And the arrow from the herbivore to the carnivore represents the transfer of chemical energy from the herbivore to the carnivore.

Injuries to the cerebrum can lead to a loss of voluntary movement and impaired speech. Damage to this brain region impacts conscious activities, while damage to other areas like the brain stem affects involuntary processes. Rehabilitation can aid recovery, although some disabilities may remain.

When the cerebrum is affected by a head injury, the individual may experience a loss of voluntary movement and impaired speech. The cerebrum is responsible for conscious functions such as problem-solving, speech, and intentional body movements; therefore, damage to this area can lead to difficulties in these areas. Injury to other parts of the brain, like the brain stem, can affect involuntary functions such as breathing regulation and heart rate.

Moreover, depending on where the stroke has occurred or the extent of the injury, one may also experience difficulties in language abilities, sensory perception, and memory, as well as potential personality changes.

Serious brain injuries such as strokes, which can be hemorrhagic or ischemic, often result in immediate and sometimes lasting symptoms that can include paralysis, confusion, and difficulty with speech and memory. Rehabilitation through various therapies can significantly improve functioning, although in many cases some level of disability may remain. It's crucial to accurately assess neurological functions following a brain injury to determine the best course of treatment.

Answer:

The bending of the colors when they pass through the prism depends on its wavelength. So violet color has a shortest wavelength as a result it bends the most and followed by indigo, blue, green, yellow, orange and red respectively.

The splitting of light into its component colors is called dispersion of light. Dispersion of white light can be done by a glass prism. The inclined refracting surface of a glass prism shows this phenomena.

When a prism is placed in a room and a beam of white light is allowed to fall on one of its refracting faces.It is found that light coming out from the other face of the prism is split into seven colors (violet, indigo, blue, green, yellow, orange, red).

ATP, a powerful particle, changes over to low-control ADP to proceed with the procedure of glycolysis

When energy is required , ADP takes one phosphate and ATP is formed.

ADP (Adenosine diphosphate) is different from ATP (adenosine triphosphate) in the number of phosphate groups in its structure. These are the source of energy for the cells and the presence of phosphate groups in these compounds indicate the strength of energy. ADP has two phosphate groups while ATP has three. When the cell requires energy ADP gains one phosphate and ATP is formed which is responsible for energy production. Then again ATP is broken down and forms ADP and Pi (inorganic phosphate) release.

Answer: maintain homeostasis

Explanation:

Homeostasis is the feature of the body resists any change occurring in it with respect to the changes happening in the external environment.

The trees shed their leaves in autumn so as to conserve water in autumn season. As in autumn season the trees may experience the scarcity of water due to lack of rainfall or low rainfall in a region. As the leaves may loose water by the process of transpiration also they will utilize water for the process of photosynthesis. The trees may experience wilting or may die. This is a process of maintenance of homeostasis in terms of conservation of water.

B. Predator and prey

Answer:

The correct answer would be B. predator and prey.

Predator and prey is a type of natural relationship in which one organism kills and consume the other organism.

For example, a lion is a predator which kills and consume deer (prey).  

During the course of evolution, prey evolves various adaptations to overcome predation and increases its survival rate.

In addition, a predator also evolves to increase its success rate in predation.

Similarly, rough-skinned newts (prey) evolve to produce poison as a defense mechanism and greater snakes (predator) evolve resistance against that poison to increase its survival rates.

The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.

1. Iodoacetamide combines with the thiol group of cysteine, thus, the protein cannot produce a disulfide bond. So, iodoacetate is an inhibitor of cysteine peptidase.  

2. In the presence of competitive inhibition, the Km increases. In the presence of a competitive inhibitor -1/Km increases, thus, 1/Km decreases, and hence Km increases. The competitive inhibitors work by combining reversibly with the active site of an enzyme. Thus, more concentration of substrate is required to attain half of the maximum velocity.  

3. In the given case, half of the molecules of the enzyme are completely active and half of the molecules of the enzyme are completely inactive.  

Irreversible inhibition is one of the reasons for the reduction in the rate of an enzyme-catalyzed reaction in the given case. The loss of activity of the enzyme molecules due to irreversible inhibition is time dependent and it is the reason behind the reduction in reaction rate.  

Reduction in the rate of reaction is proportional to the loss of activity. Therefore, a 50 percent reduction in reaction rate will result in 50 percent of the enzyme molecules to be inactive and the other 50 percent of the enzyme molecules to be completely active.  

4. The statement, that is, in the majority of the cases, the inhibitor can be removed by dialysis is not true about irreversible enzyme inhibitors.  

The irreversible inhibitors combine with the enzymes permanently and make covalent bonds with the enzyme. Therefore, it cannot get removed by the process of dialysis in the majority of cases.  

5. The correct statement is that the initial velocity increases in the presence of an enzyme.  

6. The correct statement is that the Vmax is attained when the concentration of the substrate is double the Km.  

The Km is illustrated as the concentration of substrate at which the reaction velocity reaches half of the maximum velocity. Therefore,  

Km = 1/2 Vmax

2 Km = Vmax

Vmax = 2 Km

An irreversible inhibitor inactivates an enzyme by bonding covalently to a particular group at the active site. In the presence of competitive inhibitors, Vmax decreases and Km increases. When an irreversible site-specific inhibitor is added to an enzyme operating at very high substrate levels, the reaction rate is reduced by 50%, resulting in half of the enzyme molecules being completely active and half of the enzyme molecules being completely inactivated.

An irreversible inhibitor inactivates an enzyme by bonding covalently to a particular group at the active site. When the inhibitor is bound, the enzyme active site is blocked, the substrate does not bind, and catalysis cannot occur, similar to competitive inhibition. The difference here is that the inhibition is irreversible, meaning that the inhibitor remains bound and does not dissociate from the enzyme because the enzyme-inhibitor covalent bonds are not easily broken.

Competitive inhibition is when an inhibitor reversibly binds to an enzyme at the enzyme active site; competing with the substrate for binding. A competitive inhibitor must be a molecule that is structurally similar to the substrate molecule, allowing it to interact with the enzyme active site through similar non-covalent interactions, but it does not, or cannot, undergo the same chemical reaction. When the inhibitor is bound to the active site, it blocks the correct substrate from binding and catalysis from occurring. However, as a reversible inhibitor, it can disassociate from the enzyme eventually allowing for the correct substrate to bind and the catalysis to occur.

In the presence of an irreversible site-specific inhibitor, the reaction rate is reduced by 50%. This indicates that half of the enzyme molecules are completely active and half of the enzyme molecules are completely inactivated. The substrate, on the other hand, can still bind to all available active enzyme molecules, but the binding affinity may differ for each enzyme molecule.

Crossing over is the process during which a homologus chromosome change their sequence . Crossing over occur to increase the genetic diversity. It is very important because due to this gentic varatation increase. In a first divisions of meiosis crossing over occur and sister chromatids are formed when chormosme are replicated into two stands .

Final answer:

Crossing-over is an event during prophase I of meiosis where homologous chromosomes exchange genetic material, leading to genetic variety in gametes. This exchange, or recombination, increases genetic diversity, which is vital for evolution and individual uniqueness.

Explanation:

During prophase I of meiosis, a crucial process called crossing-over takes place. Homologous chromosomes pair up gene-for-gene, forming a structure known as a tetrad, which consists of four chromatids. During this pairing, the non-sister chromatids come into proximity and exchange segments of genetic material. This breakage and rejoining of DNA segments results in the chromatids acquiring unique combinations of alleles, thereby increasing genetic diversity in the resultant gametes. This genetic shuffle, also called recombination, happens multiple times and can affect any part of the chromosome, leading to numerous genetic variations.
