What Mendel did according to the illustration would be called test-crossing.

<h3>Test-crossing</h3>

In genetics, test crossing is a procedure through which the zygosity of an individual can be determined - whether it is homzygous or heterozygous.

Test crossing requires that an organism who displays a dominant trait but whose zygosity is unknown is crossed with another organism of the same species but who displays the recessive version of the same trait.

By so doing and using the knowledge of probability, the resulting offspring from the cross will be used to determine the zygosity level of the parent.

What are characteristics of allosteric enzymes? They may have binding sites for regulatory molecules that are separate from acti
stepan [7]

Answer:

The characteristics of allosteric enzymes are listed below.

Explanation:

1 They may have binding sites for regulatory molecules that are separate from the active site.

2 They tend to have sigmoidal curve of V0 vs [S].

3 They undergo conformational change as a result of modulator binding

Which of these gymnosperms are known to be important in maintaining the balance of carbon in an ecosystem?
CaHeK987 [17]

The correct answer is:     [D]:

___________________________________________________

                    →   " redwood tree forests " .

___________________________________________________

 <u>Note</u>:  Let us consider the other answer choices.

___________________________________________________

Choice:  [A]:  "garden flowering plants" ;  is incorrect  — since these are not generally considered to be part of a true or traditional "ecosystem" ; and especially since "garden flowering plants" are, in fact, "flowering plants" —  which means that they are "angiosperms" —  <em><u>Not</u></em>  "<em><u>gymnosperms</u></em><em> </em>".

      →  Rule out:  " Choice:  [A] " .

__________________________________________________

Choice:  [B]:  " ferns and liverworts " ; is incorrect — since <em><u>both</u></em>  ferns — as well as liverworts —<u><em> are Not  </em></u><u>"</u><u><em>gymnosperms </em></u>".  

          Liverworts are "bryophytes" {which lack true vascular tissue] ; and ferns are "pterophytes" ["seedless vascular plants"].

      →  Rule out:  " Choice:  [B] " .

___________________________________________________

Choice:  [C]: " mosses and horsetails "; is incorrect ;  since <em><u>both</u></em> mosses — as well as horsetails — <u><em>are Not  </em></u><u>"</u><u><em>gymnosperms </em></u>".   Mosses are "bryophytes" (see aforementioned) ; and horsetails are "non-seed bearing plants" that spread vegetatively [underground; by asexual reproduction — <em><u>and Not by seed</u></em><em> .</em>].

      →  Rule out:  " Choice:  [C] " .

__________________________________________________

Choice:  [D]: " redwood tree forests "  ;

               — is the only answer choice provided that is a "gymnosperm".    

             Furthermore, the "redwood tree" is a conifer (i.e. "coniferous; or, "cone-bearing" plant} that reproduces through seeds spread by "cone") — and all "conifers" are a type of "gymnosperm."  

            Furthermore, "redwood trees" grow large and tall, and redwood forest communities within an ecosystem; due to there size and presence, are:  "<em><u>known to be important in maintaining the balance of carbon in an ecosystem</u></em>."

__________________________________________________

 →  As such, the correct answer is:

__________________________________________________

 →  Answer choice:  [D]:  " redwood tree forests " .

__________________________________________________

Hope this helps!

    Best wishes to you in your academic endeavors

           — and within the "Brainly" community!

Many chemotherapy drugs used to treat cancer work by modifying the mitotic spindle. Paclitaxel works by interfering with normal
Minchanka [31]

Answer:

by inhibiting the mitotic spindle plasticity

Explanation:

In eukaryotic cells, the mitotic spindle is the cytoskeletal structure by which sister chromatids are separated during cell division. Spindle microtubules are known to drive chromosome segregation, while tubulins are Microtubule-Associated Proteins (MAPs) that attach to microtubules in order to modulate their dynamics. Antimitotic drugs are nowadays widely used in chemotherapy to disrupt microtubule assembly and chromosome segregation, thereby producing mitotic arrest and cell death (apoptosis).
