Answer:
"Animals will migrate to other regions in search of food" Whenever an area in a forest is cleared up to build a road or because of any other reason the habitat of the animals residing there is destroyed.
Explanation:
Science
Answer:
a. MicroRNAs (miRNAs) bind to complementary sequences in mRNA and block its translation.
b. Piwi-associated RNAs (piRNAs) reestablish appropriate methylation patterns in the genome during gamete formation.
Explanation:
MicroRNAs
These are the small non-coding RNA molecule. These RNA consist of about 22 nucleotides. MicroRNAs are found in animals, plants and some viruses,
MiRNAs function
MicroRNAs also represented as miRNA function through base-pairing with complementary sequences of mRNA molecules. Due to this base pairing it functions as RNA silencing and regulation of gene expression.
Piwi-interacting RNA
piRNA expressed in animal cell. piRNA are the small non-coding RNA molecules which form RNA-protein complexes.
Piwi-interacting RNA Function:
Function of these complexes are epigenetic and post-transcriptional silencing of transposons.
Small interfering RNA :
siRNA molecules are the small pieces of double-stranded (ds) RNA. There length is about 21 nucleotides long. siRNA have 3' (3 prime) overhangs
Small interfering RNA Function:
siRNA overhangs are used to "interfere" protein translation. They perform this function by binding and degradation of mRNA at specific sequences
Answer:
A. ponds are shallower than lakes
Explanation:
Ponds are not larger than lakes.
Pond water may move more than lakes in some situations, but it is not a defininte.
Lakes don't always have more vegetation than ponds.
D replace toxic chemicals
The answer is <span>geographic isolation.</span>
<span>When a new species form by geographic isolation, it is called
geographical speciation or allopatric speciation. Geographical isolation is a physical separation which prevents gene
flow between distinct populations (on the island and on continent). The island populations will eventually diverge from a single species that migrated to the island. The members of the populations, which once belonged to the same species, will
no longer be able to mate and produce offspring. Eventually, the formation
of new species will occur, for example kangaroos, koala, and wombats, form that one species.</span>
