Answer:
Oxygen is necessary for the growth of all bacteria.
Explanation:
This statement is false, because not all bacteria require oxygen to produce energy and grow. The bacteria that need oxygen to grow are called aerobic bacteria. But there are also bacteria that can produce energy without oxygen, these are called anaerobic. Some bacteria can adapt to both environments, these are called facultative anaerobes bacteria.
By dating the rocks in the ever-changing crust, as well as neighbors such as the moon and visiting meteorites, scientists have calculated that Earth is 4.54 billion years old, with an error range of 50 million years.
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.
