Often organisms seem similar in their outward appearances. For example, a porpoise and a shark seem closely related, but they are not. Such similarity is the result of .
Answer: Such similarity is the result of CONVERGENT EVOLUTION
Explanation:
Evolution can be defined as the theory that was developed based on the findings of scientists that living organisms are descended from a common ancestor.
The current theory of the process of evolution makes use of present day knowledge of genes and chromosomes to explain the source of genetic variation upon which natural selection works. It postulates that although natural selection is the only force that regularly produces adaptive evolutionary change, other forces too play a part in evolution.
Evolutionary changes may show the following patterns:
--> one species gradually transform into another species.
--> one or more species evolve as offshoots of a single ancestral species to fill a wide variety of habitat. This is known as divergent evolution.
--> Many superficially similar looking species arise from different ancestral species. This is known as CONVERGENT EVOLUTION. It is shown by organisms occupying very similar kinds of environment. That is why a porpoise and a shark seem closely related, but they are not.

Explain: What triggers each step in the synthesis of tryptophan?
Hello!
What triggers each step in the synthesis of tryptophan?
Each step is triggered by a specifi c enzyme. The tryptophan operon contains fi ve genes (trpA through trpE) needed to make the amino acid tryptophan. When tryptophan levels are low, RNA polymerase binds to the operator, turning on the transcription of the fi ve enzyme genes needed for tryptophan synthesis.

Brainliest helps a lot <3
Each process is started by a unique enzyme. The five genes (trpA through trpE) of the tryptophan operon are required to produce the amino acid tryptophan.
What is a synthesis of tryptophan?The five enzyme genes required for tryptophan production are turned on by the binding of RNA polymerase to the operator when tryptophan levels are low.
Due to this, the cell either stops further synthesis or binds to a repressor, which induces the creation of the enzymes needed for its manufacture and synthesis.
When tryptophan levels are low, the trp operon is expressed (or "turned on"), and when levels are high, it is repressed (or "shut off"). The trp repressor prevents the operon from being expressed when it is linked to tryptophan.
Therefore, (trpA through trpE) of the tryptophan operon is required to produce the amino acid tryptophan.

↬Define a Cell in Biology.
The cell is the basic structural, functional, and biological unit of all living organisms.
The structural and essential component of life is the cell. Cell biology is the study of cells, including their fundamental makeup and the purposes of each of their organelles.
The first biologist to discover cells was Robert Hooke. Cells make up every living thing. They could consist of several cells (multicellular) or just one cell (unicellular) (multicellular).
The tiniest cells known to science are mycoplasmas. All living things are constructed from cells. They give the body structure and turn the nutrients from the diet into energy.
Complex cells conduct a variety of tasks for an organism's parts. They resemble masonry bricks in that they come in a variety of sizes and forms.

A strain of Neisseria gonorrhea has a mutation which has caused it to lose the ability to produce fimbriae and become less virulent as a consequence. What function has this pathogen lost
Answer: The pathogen has lost the function of the ability to adhere to cells of the body.
Explanation:
Neisseria gonorrhea is a gram negative bacteria that has the ability to attack and cause disease in man using its virulent factors. It is know to attack the urethra of both male and female producing an acute urethritis and tenda to spread locally if not treated. The virulent factors determines the ability of the organism to infect or damage it's hosts tissues and they include:
--> endotoxins
--> pilli
--> fimbriae
--> capsule polysaccharide expression
The fimbriae is one of the virulent determinants which the organism uses to attach to the host cells. As these bacteria multiple and grow, there are chances of mutation occuring. MUTATION is defined as the errors during DNA replication or induced by exposure to mutagens (like chemicals and radiation)
If the bacteria is affected by mutation, which can cause the gene for fimbriae production not to be expressed, the virulent factor of the organism will be highly affected as the first step to cause an Infection which is attachment is lost.

How do you think new proteins affect the fitness of children?
They have no effect on fitness
They increase fitness
They decrease fitness
All of the above
Answer:
All of the above
Explanation:
Protein is especially important to consume after a workout, as during exercise you are effectively breaking your muscles down. That is why it's common to see people at the gym eating protein bars or drinking whey shakes when they have finished their routine. It helps to increase the impact of their exercise.
Excess protein consumed is usually stored as fat, while the surplus of amino acids is excreted. This can lead to weight gain over time, especially if you consume too many calories while trying to increase your protein intake
Some high-protein diets include foods such as red meat and full-fat dairy products, which may increase your risk of heart disease. A high-protein diet may worsen kidney function in people with kidney disease because your body may have trouble eliminating all the waste products of protein metabolism.

what is photo synthesis ?
[tex]\sf\purple{Photosynthesis}[/tex] is a process by which phototrophs convert light energy into chemical energy.
The word “photosynthesis” is derived from the Greek words "phos" (which means “[tex]\sf\pink{light}[/tex]”) and "σύνθ-εóîς" (which means “[tex]\sf\red{combining\:together}[/tex] .”) And so it means “combining together with the help of light.”
The process of photosynthesis occurs in green plants (the primary producers in a food chain) and a few other autotrophic organisms such as cyanobacteria, purple bacteria and green sulfur bacteria.
Following is the photosynthesis formula:
6 CO2 + 6 H2O —> C6 H12 O6 ([tex]\sf\blue{glucose}[/tex]) + 6 O2 ([tex]\sf\pink{oxygen}[/tex]).
