Answer:
Biogeographic isolation is the separation of organisms of a species through geographical or biological forces.
Explanation:
Answer: Amylose
Explanation: Which complex carbohydrate contains only a-1,4-glycosidic linkages? Amylose (Amylose is formed from a-1,4-glycosidic linkages of glucose.)
Answer:
Function will be disrupted by adding the urea and regained by removing the urea.
Explanation:
The protein is one of the important biomolecule made of the polymers of the alpha amino acids that are linked together by peptide bonds. The protein works at their specific pH.
Denaturants disrupt the 3 dimensional structure of protein that affect their normal functioning. In the given experiment, the urea acts as denaturant and disrupt the protein structure. The removal of urea will reverse the denaturant condition and protein gain its function.
Thus, the correct answer is option (a).
Taxonomy used to have two groups of vertebrates and invertebrates. But invertebrates are far more diverse when it comes to the phylogenetic tree. Vertebrates all share same characteristic which is a back bone made of vertebrae, but invertebrates don’t share a common anatomical structure that all have; they are radically different in structure so they can’t be grouped in a single group. You have Arthropoda, which all have jointed limbs and segmented bodies and molt their cuticles. There’s Cnidaria, which most have tentacles and nematocysts and are radially symmetrical. And Mollusca, which have a muscular foot and a part of their body called a mantle. All these groups are invertebrates, but there’s nothing they share in common WITHOUT referring to the fact that they don’t have vertebrae. So basically that’s just an example why they can’t be grouped into one category; they all have different characteristics and are placed in different areas of the animal kingdom’s phylogenetic tree. Hope this helps
"They result in high non-response bias" is a disadvantage of online surveys.
<u>Option: A</u>
<u>Explanation:</u>
To several market analysts online surveys have become the default tool. It is fairly so. The ease of accessibility and the use of online surveys also in turn creates issues in itself. The advantages and disadvantages of online surveys are listed below:
<u>Advantages:</u>
- Accessible to most target audiences.
- Generally no cost-based geographic restrictions.
- Motivate flexible framework with countless question forms and formats.
<u>Disadvantages:</u>
- Poorly chosen networks of dissemination can contribute to skewed data, low success rates and a host of other possible problems.
- Difficulty targeting other groups of respondents, like those without internet access or samples of non-customers in niche sectors.
