Answer:

True

Explanation:

During meiotic division involved in the formation of the gametes in organisms. The meiotic division reduces the number of chromosomes by half during gamete formation.

In the given question, Horse contains 32 pairs of chromosomes or 64 chromosomes and the donkey contains 31 pairs of chromosomes or 62 chromosomes.

The gametes of a horse through meiotic division will contain 32 chromosomes and gametes of a donkey through meiotic division will contain 31 chromosomes.

When these gametes will fuse then zygote will be formed with 32+ 31 = 63 chromosomes. Since the mule contains 63 chromosomes, therefore they are sterile organisms.

Thus, true is the correct answer.

Which of the following can reduce biodiversity within a natural environment?
zepelin [54]
The answer is either b or c because bio means life and diversity means different and the ants stinging other insects get  rid of a population and maybe another species lives off of the species that ant killed.                                                                                                     
When the grasslands are converted into housing projects it gets rid of everything so no trees no animals and no diversity of living organisms other than humans

rusak2 [61]

Answer:

The reason why zebra and wildebeest graze in harmony together is because they each eat different parts of the same type of grass. Because wildebeest have no natural leader, the migrating herd often splits up into smaller herds that circle the main, mega-herd, going in different directions.

12345 [234]

Answer:

a. transcription/RNA processing : pre-mRNA, snRNA

b. translation : mRNA, rRNA,

c. not used in protein synthesis: RNA primers

Explanation:

pre-mRNA, mRNA, rRNA, RNA primers, snRNA

a. transcription/RNA processing : pre-mRNA, snRNA

b. translation : mRNA, rRNA,

c. not used in protein synthesis: RNA primers

The pre mRNA the product after transcription from the DNA is processed eg by addition of poly A tail, splicing etc before undergoing the process of translation, the snRNA also help in performing this function. In translation, the mRNA is trnslated to proteiin in the ribosomes which is also made up of rRNA and proteins. RNA primers is not needed in any of these two, only i DNA replication as the DNA polymerase is uable to begin the synthesis of adding nucleotides to a DNA strand.
