Answer:  Atoms of the same element have similar chemical behavior

Atoms of the same element can have different numbers of neutrons.

Explanation:

Atoms of the same element have similar chemical behavior as it is decided by the number of electrons which remains same for same elements.

Mass number is defined as the sum of number of protons and neutrons that are present in an atom.  Atomic number is defined as the number of protons or number of electrons that are present in an atom.

Isotopes are elements which have same atomic number but different mass number.  That means they are same elements with same number of protons and electrons but different number of neutrons. Example: _1^1\textrm{H} and _1^2\textrm{H}

Absorbe nutrientes por medio de micro vellosidades que recubren y aumentan la superficie de absorción
Likurg_2 [28]

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.

Anna [14]

The importance of conservation of habitats is that habitat conservation protects biodiversity in the region.

<h3>Conservation of habitats</h3>

Habitat can be defined as an environment that is made up of resources that are used by a particular organism.

There are different types of habitat which include:

  • aquatic habitat,

  • terrestrial habitat and

  • arboreal habitat.

These habitats needs to be conserved to maintain biodiversity which is an essential part of global food security.

scoundrel [369]

Answer:

The fraction of the offspring that will show the phenotype produced by the recessive c allele is 1024/4096 = 0.25 A-BbccDdE-Ff = 25%

Explanation:

You can calculate the fraction of the offspring that will show the phenotype produced by the recessive c allele by making the punnet square for each gene and then multipling the phenotypic proportions, like this:

Cross) AAbbCcDDEeff     x      AaBBCcddEEFF

Cross For each gene by separately:

  • Parental )        AA    x    Aa

       Gametes)  A    A         A    a

        F1)             2/4 AA  

                          2/4 Aa

  • Parental )        bb    x    BB

         Gametes)  b    b         B   b

          F1)                   4/4 Bb

  • Parental )        Cc    x    Cc

        Gametes)  C    c         C    c

         F1)             1/4 CC

                           2/4 Cc

                            1/4 cc

  • Parental )        DD    x    dd

       Gametes)  D    D          d    d

        F1)             4/4 Dd

  • Parental )        Ee    x    EE

        Gametes)     E     e      E     E

         F1)             2/4 Ee

                           2/4 EE

  • Parental )        ff    x    FF

         Gametes)     f     f      F     F

          F1)             4/4 Ff

So, fraction of the offspring that will show the phenotype produced by the recessive c allele is:

4/4 A-  x  4/4 Bb   x   1/4 cc   x   4/4 Dd   x  4/4 E-   x   4/4 Ff =  

1024/4096 = 0.25 A-BbccDdE-Ff =25%
