Answer:
Light bounces off surfaces property most likely believed by Janssen about light during the time of his invention
Explanation:
Zacharias Janssen is ascribed as a man to discover the compound microscope. Its purpose is to amplify diminutive things so characters can analyze them. There is a mirror attached under the microscope and when light bounces off the mirror it reaches through and nearby the specimen being viewed.
Some elements do not receive light. When a light wave is reflected off a facade, it proceeds back off at an angle similar that the wave beats the surface. Using these more innovative concepts about light enacted scientists to compose new inventions.
Answer:
option A
Explanation:
In carrying out these experimental procedure, the same restriction enzyme that is used to cut out the gene of interest should also be the same used for the cutting of the plasmid to generate sticky ends. Then the desired gene is inserted into the cut plasmid then treatment with DNA ligase. Purified DNA ligase is utilized in gene cloning to join/ligate DNA molecules together forming a recombinant DNA. Thus, step 3 should be carried out after step 4.
In human, Oogenesis in comparison to spermatogenesis is different in that Oogenesis does not complete meiosis until after fertilization, but spermatogenesis is complete before the sperm leave the body. Oogenesis is the process by which the female gametes, or ova are created in the female's ovary. Spermatogenesis is the process in which males synthesis sperms. The two process are part of gametogenesis which involves meiosis type of cell division, in which a diploid cell divides into four haploid daughter cells.
I suggest you watch the Amoeba Sisters video again, 1-2x and take notes.
Biomagnification is when toxins / heavy metal are present in small amounts in fish, but accumulate as you move into higher trophic levels. This is one reason why it can be toxic for humans to eat tertiary or quaternary consumers, such as swordfish, shark, etc.
