1. Phytoplankton, krill, fish, penguin
2. Baleen whale, smaller toothed whale
3. krill
4. the phytoplankton are the producers, they make their own food from the sunlight just as plants do.
5. herbivorous zooplankton, phytoplankton
6. One type is a herbivore it snacks on plants. The other type is a carnivorous type of zooplankton it eats smaller animals.
7. Draw a pyramid with several layers. at the bottom write phytoplankton. above that layer write zooplankton, not the carnivorous type. above that write 1st level carnivorous consumers, such as the fish, krill, other birds, and small squid. above that write 2nd level carnivores like the leopard seal, penguin, and elephant seal. Then above that write Baleen whale, smaller toothed whale, and a sperm whale.
Answer:
C (Prophase)
Explanation:
All cells undergo division in order to produce more daughter cells. Cell division occurs immediately after the interphase, which is a resting and preparatory phase for mitosis or cell division. Prior to cell division, the DNA is found to be coiled around histone proteins to form a structure called CHROMATIN. The process of cell division occurs in four phases; Prophase, Metaphase, Anaphase, and Telophase.
In the Prophase stage, which is the first stage of mitosis, this Chromatin begins to condense or becomes compact by undergoing further coiling into a visible X-shaped structure called CHROMOSOME. This shape of the chromosome is as a result of the replication into sister chromatids that occurred in the S-phase of interphase.
Answer: B, C
Explanation: Scientists use radiometric dating of meteorites and analyze the impact craters on planetary body surfaces to learn about the age of the solar system and its planetary bodies.
