Answer:
D. Animal cells would not have the materials needed to produce energy in cellular respiration.
Explanation:
The correct answer is
DNA polymerase is the enzyme that catalyzes the addition of a nucleotide onto the 3' end of a growing DNA strand. DNA polymerase adds nucleotides one by one to the 3’ end of the growing DNA chain, incorporating only those that are complementary to the “old” DNA strain.<span>The addition of nucleotides requires energy which comes from the nucleotides themselves (phosphates).</span>
Answer:
The producers-Sea weed-Perform photosynthesis.
The filter feeders- sponges, chiton-eat floating planktons.
Grazers -Snails,mussels feed on- floating planktons.
Carnivores such as sea stars feeds on snails
Explanation:
- The producers are placed at the bottom level in energy pyramid and are prime factor in the aquatic eco system which provides energy and perform photosynthesis with the help of water,sunlight and chlorophyll.
- The filter feeders are those that feeds upon small particles that are present in the water.
- Grazers are those organisms that feeds on producers like phytoplanktons.
- Carnivores are those organisms that feeds on herbivores.
Macroevolution can cause significant changes in the frequencies of alleles, that can ultimately result in speciation (forming of new species).
Various large-scale events like climate change and continental drift can greatly influence the distribution of species and adaptive radiation of different groups that can fill vacant ecological niches.
The changes in gene regulation and genetic mutations can also contribute to macroevolution by producing novel traits and adaptations.
The cytosol consists mostly of water, dissolved ions, small molecules, and large water-soluble molecules (such as proteins). The majority of these non-protein molecules have a molecular mass of less than 300 Da. Hope I’ve helped ;)
