Answer:

Option C

Explanation:

As per the paleontologists, the anchored tubular structures of fossilized  Funisia dorothea showed dense clusters which are believed to be formed by mating of floating egg and sperms in the water. Also traces have been found that states asexual mode of reproduction through budding where buds were formed in the same way as that of coral, sponges etc and then these buds grew into full sized Funisia dorothea. Thus, the fossil species have the complex ability to produce both sexually and asexually.

Which of the following sequences shows a frameshift mutation compared to the wild-type mRNA sequence?
Butoxors [25]

Option C:

B. wild-type 5-AUGCAUACAUUGGAGUGA-3 mutant 5'-AUGCAUACAUCUGGAGUGA- 3' 

Explanation:

A frameshift mutation is a genetic mutation such that the triplet nature of gene expression by codons, the insertion or deletion occurs in such as way that it alters the complete sequence of 3 codon sets and can change the reading frame, resulting in a completely different translation from the original.

As it is pertinent to understanding that all genes are normally translated in sets of 3 codons, which typically describes and explain a unique amino acid sequence. Thus, if a frame shift mutation occurs, it can affect many amino acid sequences and finally the entire protein.  

If we look at option B:

wild-type 5-AUG   CAU  ACA  UUG  GAG  UGA-3  

mutant 5’-    AUG   CAU  ACA  UCU  GGA  GUG  A-3’  

An insertion of a base Uracil showed at the end of 3rd codon which affected and altered the whole sequence of codon triplets. This changed all next codons and finally all next amino acids will be altered.

Answer:

less than 1%

Explanation:

The approximate percentage of the geologic time that humans have existed on the Earth since its origin is less than 1%.

The earth is about 4.6 billion years and much of its history has been without the present of human activities.

  • Hominis were the first human to appear on the surface of the earth.
  • This was in the Miocene epoch which was about 6 million years ago.
  • Compared to the age of the earth, this time lapse is very small and not up to 1%.
  • Life first appeared on earth about 3.5billion years.
  • Since then evolution has taken its due course to give what we have today.

Plenty of food, water and suitable temperature are the conditions required for the growth of fungi. Is it true or false?
jonny [76]
<h2><em>True</em></h2>

<em>Explanation:</em>

<em>Some species of fungi do grow better at warm temperatures (70-90°F), but there are some that thrive in very high temperatures of 130-150°F and some that will thrive in very low temperatures below 32°F (below freezing). ... Water: Fungi need lots of water to grow. For most fungi this is true. :)</em>
