If the environment changes quickly and no individual members of a species are able to survive in the new environment, then the species will become extinct in that environment
3% of the Earth's water is freshwater.<span />
The answer would be 25%
Carbon 14 is radioactive material with 5700 year of half-time which will change it into carbon-12, a more stable substance. If the age of the fossil is 11,400 years old, then the amount of half-time passed would be: 11,400 years/ (5,700years/ half-time)= 2 half-time.
Since it undergo 2 half-time, the percentage should be: 100% * (1/2)^2= 25%
The sequence of nucleotides in the template strand of DNA could code for the polypeptide sequence Phe-Ser-Gln is AAG, AGG, and GUU.
<h3>What are Nucleotides?</h3>
Nucleotides may be defined as a molecule that consists of a nitrogen-containing base, a phosphate group, and a pentose sugar.
The codons that codes for the given amino acids are as follows:
- Phe = UUC
- Ser = UCC
- Gln = CAA.
mRNA is synthesized from a template DNA strand based on a complementarity mechanism.
Therefore, the sequence of nucleotides in the template strand of DNA could code for the polypeptide sequence Phe-Ser-Gln is AAG, AGG, and GUU.

Answer:
C. Ringed seal
Explanation:
A marine food web illustrates how energy is passed from one organism (level) to another in this aquatic rich ecosystem.
In the following food web, the interaction goes like this:
- The Arctic cod feeds on plankton and silverslides and it is preyed upon beluga whales and ringed seals.
- The sea duck goes to the bottom of the ocean to feed on benthic organisms and also consumes plankton and silverslides. It doesn't really have predators.
- The beluga whale doesn't really have predators, but it feeds on fish such as silverslades and Arctic cod.
- Ringed seals feed on plankton and Arctic cod and are then consumed by polar bears.
Therefore, according to this information, all organisms except the ringed seal feed directly on silverslides.
