Crossing over refers to the mechanism of recombination, this process being characterized in that increases the genetic variation

Spermatogenesis refers to the mechanism of formation of male gametes (sperms), while oogenesis is the process of formation of female gametes (oocytes)

Explanation:

Telophase I is the final step in meiosis I. During telophase I, the nuclear membrane is formed around the decondensed set of chromosomes and the nucleoli reappear.  

Spermatogenesis refers to the process by which haploid male germ cells (sperms) are generated within the seminiferous tubules in the testis, while oogenesis refers to the process of differentiation of the female egg cells (ova or oocytes) in the ovaries. Spermatogenesis is known to produce small and motile spermatic cells, while oogenesis is known to produce bigger non-motile oocytes.

alexgriva [62]

The complete question is :

The success of plants extending their range northward following glacial retreat is best determined by _____.

A) whether there is simultaneous migration of herbivores

B) their tolerance to shade

C) their seed dispersal rate

D) their size

Answer: The seed dispersal rate

Explanation:

The  seed dispersal can be defined as the movement of the seeds away from the parent plant. The ability of the plant to extend is completely dependent on the ability of the plant to disperse its seeds.

Plants have very limited ability, they need vectors to carry its seed from one place to another.

The biotic and abiotic vector both are involved in carrying the seeds which helps in expansion of the trees.

hence, the correct answer is option C

Maru [420]

Answer:

In a particular case of secondary succession, three species of wild grass all invaded a field. By the second season, a single species dominated the field and the other two species had a lower relative abundance. A possible factor contributing to the abundances of these species in this example of secondary succession is <u>inhibition</u>.

Explanation:

Trees are great examples of allelopathy in plants. Some use their allelochemicals to inhibit germination or impede development of nearby plant life. Most allelopathic trees release these chemicals through their leaves, which are toxic once absorbed by other plants. Black walnut is a prime example of this.
