The fossil record of Antarctica shows the presence of tropical plants, such as one particular species related to the present day breadfruit. Most plants cannot survive in prolonged temperatures of less than 6 degrees Celsius. Antarctica is freezing all year round and could only have supported tropical and sub tropical plants if it was once much closer to the equator.
The presence of fresh water species also suggest that the continent was closer to the equator. Antarctica is frozen solid with a thick ice sheet.....rivers would be frozen solid all year round or would be limited to water movement under glaciers that melt as a result of pressure and friction. This environment is not suitable to support large fresh water organisms.
Answer: The correct answers are-
1) C) S Phase
2) A) prophase, metaphase, anaphase, telophase.
Cell cycle corresponds to the division of cell, which occurs primarily through two phases that are - Interphase ( which has G1, S, and G2 phase) during which cell grows, duplicates its genetic material and M ( mitotic phase) phase during which cell divides.
S phase ( synthesis phase) corresponds to the duplication of the genetic material (DNA). It takes place place after G1 ( Gap 1 phase) phase.
2) Mitosis is a type of cell divison in which one parent cell divides to produce two daughter cells with same number of chromosomes. Prophase is the first phase, followed by metaphase, anpahse, and telophase.
Answer:
1. Protein - build lean muscle and strengthen tendons
2. Lipids - insulation and long-term energy
3. Carbohydrates - provides quick, easily digested energy
4. Nucleic Acids - repair and replicate DNA and RNA
Explanation:
a. Think of protein as what helps your muscles grow and strengthen
b. Think of lipids as fats (blubber, the extra fat, helps insulate seals from the cold)
c. carbohydrates are found in starch and bread products, and are used to help build up energy prior to marathons.
d. nucleic acids - think of nucleus; it is where genetic material is located, and also where DNA and RNA is located.
Answer - Fewer Species or Little of life
Reasoning - Usually in an island surrounded by water has little of life because the limited resources but also if there were to be species living within the island it will be very little because of the resources they compete. Especially moving away from mainland since (No Humans) lol.
The moment it is exposed into the environment
