The answer is; C
Most often some ancestral characters are preserved in an organism's development hence can be used to study evolutionary relationships. One of these features is the gill slits in embryos. These have been used to postulate that all land organisms, that exhibit gill slits in their embryonic development, emanated from a common fish ancestor. In humans, these gill slits later develop in the pharyngeal.
B. Form a hypothesis
C. Test the hypothesis with an experiment
or
D. Draw conclusions
Kathy's survey falls under option D - drawing conclusions. This means she gathered data through her survey and made conclusions on how many of her classmates are left-handed and right-handed.
In the given scenario, Kathy is conducting a type of research to identify the number of her classmates who are left-handed and right-handed. This activity falls under D. Draw conclusions. Through the survey, Kathy is collecting data, analyzing it, and then drawing conclusions based on the information she has gathered.
It's important to understand the steps of scientific investigation: Usually, recognizing a problem is the first step where questions about an observed issue are asked. Forming a hypothesis is the second step where potential answers to the problem are proposed. These hypotheses are then tested through experiments. Finally, conclusions are made based on the results of these experiments.
In this case, Kathy has skipped right to drawing conclusions. Through her survey, she has gathered information and based on that information, she can draw a conclusion on how many of her classmates are left-handed or right-handed.

Coelomates are animals which body cavity (coelom) is filled with fluid. Fluid surrounds organs, protects them and allows their free movement and growth. All vertebrates and some invertebrates, such as mollusks, annelids, and arthropods, are coelomates.
Answer:
The answer to this question would be: antiviral agents that block any of the steps in the transcription process, since without newly produced RNA, or DNA for the new virions, it would be impossible for the virus to replicate itself and thus spread out to infect further. An example of such a drug is aciclovir, and what they do is inhibit, or prevent, the transcription process, either of DNA, or RNA depending on the invading virus, so that viral proteins cannot be coded for and the new virions cannot be assembled.
These agents usually are nucleotide analogues that mimick the DNA, or RNA, that the virus will need in order to replicate its genetic material for the new viruses. However, since they are not the correct material, these analogues will inhibit correct replication, or further coding, of the genetic material. This in turn will ensure that either no proteins, or weak proteins, will be produced and the virus will be left weakened for the attack of the immune system.

true
Explanation:
Amphibian skin is permeable, meaning that it's not a solid barrier to the environment. They can absorb oxygen right through their skin. ... Amphibians have the amazing ability to re-grow not only tails but also toes and even legs to some extent!
