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.

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.
A researcher stimulates, with a small electrical charge, a portion of a cat's limbic system. The cat suddenly jumps and acts as if it is fighting. What portion of the limbic system was stimulated
Answer: amygdala
Explanation:
The limbic system, refers to the set of brain structures that's located on the sides of the thalamus. The function of the limbic system include olfaction, behavior, emotion, and long-term memory.
Since the cat suddenly jumps and acts as if it is fighting, the portion of the limbic system that was stimulated is the amygdala.
Which 'if any' of the following are true? Aquatic animals present a greater risk to divers than any other factor.

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:
the process by which green plants and some other organisms use sunlight to synthesize nutrition form carbon dioxide and water.

¿Cómo puede el río cambiar el lugar de la topografía?
Answer:
Los mapas topográficos utilizan el sistema de representación de planos acotados, mostrando la elevación del terreno utilizando líneas que conectan los puntos con la misma cota respecto de un plano de referencia, denominadas curvas de nivel, en cuyo caso se dice que el mapa es hipsográfico.
Explanation:Además de los campos mencionados anteriormente, la topografía es fácilmente aplicable a cualquier trabajo o proyecto donde se necesite realizar planos, obtener datos de un terreno y ubicar puntos en la superficie terrestre con gran precisión y rigurosidad técnica.Es posible determinar la posición de un punto sobre un plano horizontal: a partir de un solo punto conocido, por levantamiento de poligonales , un método que consiste en medir distancias horizontales y azimut a lo largo de una línea quebrada (ver Sección 71);

Match the structure with the correct type. A structure type may be used more than once. 35.bat wing and mouse arm_____A. homologous structure 36.reptile foot and bird foot ____B. analogous structure 37.dolphin fin and fish tail ____C. vestigial structure 38.eves on a blind cave fish ____ 39.snake tongue and dog nose ____
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.

The features of alveoli for the efficient exchange of gases.
A. Thin wall, moist layer and less blood vessels
B Thin wall, moist layer and more blood vessels
C. Thick wall, moist layer and more blood vessels
Explanation:
The alveoli are lined with mucus and are surrounded by a network of blood capillaries. They have very thin walls for gases to be absorbed through. An individual air sac is called an alveolus. The layer of moisture in the alveoli allows gases to dissolve so that they can diffuse quickly.
