Answer: alternative A
Explanation: The deeper the layer in water, the <u>less light reaches it</u>. In deeper layers, therefore, it becomes difficult, if not impossible, to photosynthesis to occur. Having in mind that <u>phytoplankton and photosynthetic organisms depend on photosynthesis to survive,</u> they won't appear in such dephts.
Answer:
The correct answer will be- homologous structures
Explanation:
The history of how life has survived on the earth can be studied through a field of biology called evolutionary biology.
Studying the anatomical features of the organisms and the collected specimens (fossils) shows that some organisms posses similar anatomical structures which could be performing different functions.
The structures in organisms which are similar in their structure are thought to have derived from a common ancestor and are known as "homologous structures.
"
Thus, homologous structures are the correct answer.
Rosalind Elsie Franklin was an English chemist and X-ray crystallographer who made contributions to the understanding of the molecular structures of DNA, RNA, viruses, coal, and graphite. Although her works on coal and viruses were appreciated in her lifetime, her contributions to the discovery of the structure of DNA were largely recognised posthumously. Born to a prominent British Jewish family, Franklin was educated at a private day school at Norland Place in West London.
Yes, living things break down polysaccharide into simple sugars.
Natural selection played a role by eliminating the snakes that had different colored bands. Those snakes with bands with different colored bands were most likely eaten because animals knew they didn't resemble the poisonous snake.
