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.

Question: What is the expected percent change in the DNA content of a typical eukaryotic cell as it progresses through the cell cycle from the start of the G1 phase to the end of the G2 phase
a. -100%
b. -50%
c. +50%
d. +100%
Answer:
d. +100%
Explanation:
S phase comes between G1 and G2 phases of the interphase of a cell cycle. S phase of interphase includes replication of DNA. The process of DNA replication doubles the amount of DNA present in the cell. The newly synthesized DNA is accommodated in the sister chromatids of chromosomes. Therefore, a cell with 2C DNA in the G1 phase would have 4C DNA at the end of the G2 phase. So, there is a +100% increase in the DNA content of a cell as it proceeds from G1 to the end of the G2 phase.
Answer: C. On a sloped parking lot
Surface runoff can be referred as the flow of water, that occurs when the excess water flows from the storm water, melt water, flood, rain streams and rain fall. The fast moving water current takes along with it superficial layers like surface and sub- surface layers of soil. Hence, causes water erosion of soil.
The slope parking lot will favor, surface runoff more likely than in a grassy prairie, mulched flower bed, or in a sand pit because the slope will provide a surface for free flow of water. There are chances that water gets absorbed by the soil in the grassy prairie, mulched flower bed and sand pit. Whereas the slopy surface of parking lot will not allow the water retention by soil, instead will accelerate the flow of water.

Protein Function may be terminated, disrupted, destruction of both the secondary and tertiary structure through the process called DENATURATION. Denaturation process does not break the primary structures since the link or sequence of peptide bond are greatly hold by Hydrogen bonding.
