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.
11. The heart is made of *

How do wales differ from fish
Answer:
Whales are mammals that need air from the sea's surface to survive. Whales are capable of giving birth to live young. Fish have gills and use them to draw oxygen from the water. The majority of fish lay eggs. Whales and other marine animals with horizontal tail fins, such as dolphins, have vertical tail fins, while fish have vertical tail fins.

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]).

Answer:
35. A. homologous structure
36. B. analogous structure
37. B. analogous structure
38. C. vestigial structure
39. B. analogous structure
Explanation:
A homologous structure is a similar structure/trait found in different species because they diverged (evolved) from a common ancestor, i.e., these species share a common ancestor that had the homologous structure/trait. A homologous structure may have the same or different functions in the descendants. Conversely, an analogous structure is a similar structure/trait that evolved independently (i.e., by convergent evolution) in different species to have the same function, thereby these species don't share a common ancestor with the trait. Finally, a vestigial structure is a rudimentary biological structure found in an organism that has lost its original/ancestral function (e.g., the appendix in humans or the hindlimbs of the snake). Vestigial structures provide strong evidence for evolution by use/disuse of body parts.
Homologous and Analogous structures differentiate in origin and function. Vestigial structures have lost their function. A) Homologous, B) analogous, C) analogous, D) vestigial, E) analogous.
What is an homologous structure?Homologous characters are the structures of different organisms that,
are composed of the same basic elements. share the same position in the body and the same relationship with adjacent structures.share the same embryological development.These structures might express some variations between the organisms that might be related to their function and to the environment. Their function is not necessarily the same in all the organisms involved.
These homologous characters are present in organisms related that share a common ancestor.
What is an analogous structure?Analogous structures are those body parts of different organisms that accomplish the same function, but they are originated from different areas. These structures do not share the same origin.
What is a vestigial structure?Vestigial structures are those body parts, genetically determined, that have been retained during the evolution of the taxonomic group but have lost or reduced their original function.
Such vestigial structures were plenty functional in the ancestors of new species, but now are typically degenerate, stunted, or rudimentary, and tend to be much more variable than homologous non-vestigial parts.
According to these definitions, we can answer the questions.

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.

What can happen when a community becomes isolated from the rest of its species for many generations?
a) Competition between individuals will decrease.
b)The community will grow more slowly.
c)A new species can form.
d)There would be no effect on the community.
Answer:
C) A new species can form.
Explanation:
This is the concept of genetic drift, where a species being isolated gets an unnatural change in the gene pool, and thus can evolve differently.

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.

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.
