Which scenario would most likely result in cooperative hunting?
Elenna [48]

Answer:

<h3>scenario that would most likely result into cooperative hunting is where there are few and limited number of rabbits in an area, and as such, it is difficult to hunt rabbits due to scarcity. In order to increase their chances of catching rabbits, wolves in that area would cooperate together and hunt in packs.</h3>

The epidermal tissue of a plant prevents _________. predation asexual reproduction water loss none of the above
laila [671]
The epidermal tissue would form a boundary between the plant and it's environment so it probably wouldn't prevent asexual reproduction. Predation doesn't making sense because it's a plant, not an animal prey. Water loss is the best answer because the thick boundary prevents some water from evaporating.

A complete plant gene containing four introns and five exons is carried on a 6.0-kb DNA fragment. DNA sequencing analysis finds
damaskus [11]

Answer and Explanation:

the total length of the gene is 6,000 base pairs (or) 6.0 kb and it has five exons, four introns and a 1,000 base pair length flanking region for the transcribed region.

Hence, each exon has (1500/5) = 300 by

each intron has (3500/4) = 875 by and

flanking segment (5' and 3') length for the transcribed region would be (1000/2) = 500 bp.

The gene segment is as shown in the <em>1st diagram attached below </em>

In eukaryotes, transcription takes place in the nucleus which results in the synthesis of hnRNA (heteronuclear ribonucleic acid). This hnRNA (pre-RNA) has both introns and exons, however when it is synthesized or while it is being synthesized the Spliceosomal complex removes introns from hnRNA and becomes converted into mRNA (messenger RNA) in the nucleus itself.  

(<em>second diagram explains further)</em>

Now the synthesized mRNA reaches the cytoplasm. So, if mRNA collected from the nucleus and cytoplasm will have the same length of about 2,500 base pairs only. Therefore, after the commencement of northern blot analysis both mRNA will yield the same kind of result and have unique length.
