Answer:Nucleus

Explanation:

The organelle named Nucleus is known as the brain of the cell. It plays a vital role in the cell division and from a single cell the cells keep on dividing and forms a new plant.

This organelles gives instruction to the plant body for many of the functions. One of them is cell division.

The cell division is the process by which different parts of the plant develop.

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%

Which of the following describes a way to recover items and use them for energy?
dybincka [34]

One of the ways which describes a way to recover items and use them for energy is the using recovered biomass when appropriate.

<h3>What is biomass energy?</h3>

Biomass energy can simply be defined as that energy which is generated or synthesized by living things or once living things

So therefore, one of the ways which describes a way to recover items and use them for energy is the using recovered biomass when appropriate.

Medicines are often administered in pill form. In many cases, the active ingredient of the pill (the drug) is joined to another
Natasha_Volkova [10]

Answer:

Option B, ionic bonds; salt

Explanation:

All medicines either in the form of pills or liquid interact with our body by forming a bond with target specific receptors. For instance if a pain killer is taken then it shall form bond with receptors produced by pain and inflammation

So medicines are basically chemical which interact with biomolecules such as enzymes, nucleic acid, hormones, ions etc. by forming ionic bond, hydrogen bond, van der wall force etc. in the active site of enzyme.    

These salt molecule remain stable in normal conditions but as they come in contact with digestive system of the body (with different pH) they release the drugs

Hence, option B is correct
