Sobre la pregunta:
Cucigrama. Pregunta 1 vertical. Absorbe nutrientes por medio de micro vellosidades que recubren y aumentan la superficie de absorción
Answer:
Intestino delgado
Explanation:
El intestino delgado es el organi mas largo del tubo digestivo, pudiendo medir 7 metros de longitud y 3 cm de diametro. Se caracteriza por estar sumamente plegado sobre si mismo. La primera porcion, llamada duodeno, recibe secresiones de glándulas biliar y pancreática, y las mezcla con enzimas digestivas. Esta mezcla se encarga de degradar la comida y transformarla en sustancias solubles, como amino ácidos.
Es en el intestino delgado donde ocurre la absorción de nutrientes. Las paredes intestinales estas cubiertas por microvellosidades que aumentan la superficie de absorción.
Las microvellosidades son células que componene el epitelio columnar, y que extienden proyecciones hacia el lumen del organo.
Mutations can affect the coding of "base pairs" in the chromosome of an individual by various means like:
1) by Deletion
2) by Duplication
3) by Translocation
4) by Inversion
After all that changes, codes deviates from normal information & can affect individual in negative way. In that manner, Mutations affect individual traits.
Hope this helps!
Complete question:
Thinking creatively about evolutionary mechanisms, identify at least
two schemes that could generate allelic polymorphism in a population except natural selection that favors heterozygotes.
<u>Select the two correct answers.</u>
-inbreeding among individuals in the population
-purifying selection against mutational variants of alleles in the population
-continuous migration of individuals with new alleles into the population
-mutations that do not severely affect viability and reproductivity
-genetic drift of alleles common in the population
-events leading to genetic bottleneck effect
Answer:
The two events that might favor heterozygotes among the options are
- The Continuous migration of individuals with new alleles into the population
- Mutations that do not severely affect viability and reproductivity. These might favor heterozygous frequencies.

Answer: B. littoral zone
Explanation: Their primary prey, insects, live or fly near the shallow and outside edges of ponds and lakes. There is also less predator fish at the edges of lakes and ponds.
