Answer:
See the answer below
Explanation:
Science is a body of knowledge through which humans try to understand the natural world and make the best out of it. The usefulness of science can be seen from its applications. Some of these applications include;
1. Health: through science, humans have been able to gain insights into the causes of various diseases and profer solutions to them. The continuous investigation into diseases and drugs have ensured that the human population remains healthy to an extent.
2. Food and Agriculture: scientific advancements have ensured the domestication of useful plants as foods, drugs, or industrial materials. Through biotechnology, improved breeds of crops have been produced and sustainable food production for the human populace has been promoted.
3. Improved lifestyle: Advancement in science has helped man to be able to live an improved lifestyle. The application of scientific knowledge has led to the invention of products that can automate processes that otherwise would have been done manually. Examples include the invention of vehicles, washing machines, grinders, air conditioning, etc.
4. Communication: Science has also revolutionized how humans communicate with each other. The discovery of waves and how they can be manipulated for improved communication has led to the invention of phones, radios, televisions, and so on.
5. Infrasctures and aesthetics: Through various advancements in science, infrastructural facilities for improved living experience and beautification of the environment for aesthetic purposes have been incoming.
This is a very easy paragraph analysis question. The answer is c. "Over time, scientific knowledge is reevaluated and extended through new scientific research." The reason why the answer is C., is because the chronological order of the study of genetics is as follows:
- Mendel does his pea plants experiments, but did not know how traits were passed to the offspring.
- Avery concludes that DNA is the "material" that passes on traits to the offspring, probably using Mendel's research and his own research (pneuonimia virus research) as well.
- Since the existence of DNA was published, Watson and Crick used it to identify an accurate model of the structure of DNA, using the four bases: cytosine, adenine, guanine, and thymine.
Overall, we see a trend of scientists publishing results based on what scientists did before.
Answer:Dog
Explanation:
A dog is at a higher advantage because it has a larger jaw which could easily be used to crush a cat during a fight
Answer:
0
Explanation:
This question involves two genes; A and B. According to the question, two parents are crossed as follows: AABB × Aabb. The parents will produce the following gametes:
AABB- AB, AB, AB, AB
Aabb - Ab, Ab, ab, ab
Using these gametes in a punnet square (see attached image), the offsprings in the following proportion will be produced:
AABb = 4/16 = 1/4
AaBb = 4/16 = 1/4
Therefore, none (0) of the offsprings will resemble the phenotype of the second parent (Aabb).
