True, because the kidneys filter out waste in most living things.
Answer:
Fungi and green alphae share their food among each other.
Explanation:
The alphae or the cyanobacteria benefit their fungal partner by producing organic carbon compounds through photosynthesis.

Answer:
Skin color, a polygenic trait, is also determined by environmental factors.
Explanation:
In humans, skin color or pigmentation is a polygenic trait and is also determined by environmental factors such as exposure to the sun.
Polygenic traits are the traits which are controlled by two or more genes located on different chromosomes. For example, height, skin color, and color of the eyes.
John and Pat carry identical DNA however they exhibit different interaction of the polygenes and working conditions (environmental factors). For example, John works in a movie theatre and thus does not have much exposure to sun whereas Par works on the beach which is an open area and thus experience a lot of exposure from the sun.
Exposure to the sun leads to the darker skin and thus polygenic interactions and different environmental conditions lead to the variation in skin pigmentation in John and Pat.
Answer:
Afecta a la estructura primaria de las proteínas.
Explanation:
Las proteínas tienen 4 niveles de estructura:
- Estructura primaria: es la secuencia de aminoácidos que forman la cadena peptídica de la proteína.
- Estructura secundaria: es el plegamiento de la cadena por unión con aminoácidos de la misma cadena dándole a la proteína la forma de alfa hélice o de lámina plegada.
- Estructura terciaria: la estructura secundaria de la proteína se pliega dando a la proteína una estructura globular, la cual hace a la proteína soluble, o fibrilar, la cual hace a la proteína insoluble.
- Estructura cuaternaria: dos o más proteínas con estructura terciaria se unen.
Si la xerodermia afecta la secuencia de aminoácidos, afecta la estructura primaria de la proteína ya que esta es el orden en que los aminoácidos se juntan para formar la cadena peptídica.
