Biology
1 answer:
abruzzese [7]3 years ago
3 0

Answer:

4. Ribosomes are tiny glanular structures that are either floating freely in cytoplasm or are bound to endoplasmic reticulum.

5. Translation.

6. Eukaryotic ribosomes are ten times larger than prokaryotic ones.

7. Not sure about this.But they are necessary for protein synthesis as they assemble amino acids into protein chains.

8. Ribosomal RNA is part of ribosome.These complex structures catalyze the assembly of amino acids into protein chains.They also bind tRNAs and various accessory molecules necessary for proteins.

9. When a ribosome is not working,it disassembles into two smaller units.

In an experiment, you create two groups of liposomes in a solution containing 0.1 M NaCl—one made from red blood cell membranes
mars1129 [50]

Answer:

As liposomes with red blood cell membranes burst more rapidly than those made from egg membranes, we consider these liposomes as more hypertonic respect to water, than those derived from frog egg cells.

Explanation:

Osmosis is a process where water can cross a semipermeable membrane in a gradient way.  Water tends to move from a high concentration of solvent to a low concentration.  Then, water goes in through the liposome to dilute its solute content, as it's not easy for molecules inside to go out of the usually impermeable membrane bilayers.

When writing an organism’s name using binomial nomenclature, what is the proper forum? (what is capitalized, what is lowercase,
weeeeeb [17]
The binomial name will include the genus and species in that order. Both are italicized with the first letter of the genus being capitalized and the species being all lower case. For example:
Emperor Penguin = Aptenodytes forsteri (can’t italicize on this app but the scientific name would be)

Bezzdna [24]

Answer:

A capstone course, also known as capstone unit or a senior thesis or senior seminar serves as the culminating and usually integrative experience of an educational programtion A capstone project plays a vital role in preparing a student for the future course of learning. It gives students a chance to retain whatever they have been learning during their college studies and apply it once they pursue a specific academic profession in the college.

A plant has the genotype AAbbCcDDEeff, where each letter represents a different gene. This plant is crossed with another whose g
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%
