The genes for the traits that Mendel worked with are either all located on different chromosomes or behave as if they were. How did this help Mendel recognize the principle of independent assortment? a. Otherwise, his dihybrid crosses would not have produced a 9 : 3 : 3 : 1 ratio of F2 phenotypes. b. The occurrence of individuals with unexpected phenotypes led him to the discovery of recombination. c. It led him to the realization that the behavior of chromosomes during meiosis explained his results. d. It meant that the alleles involved were either dominant or recessive, which gave 3 : 1 ratios in the F1 generation.

The cell cycle consists of two main phases: _____. interphase and M phase G0 phase and S phase M phase and S phase interphase and G2 phase

Answers

Answer: The correct answer is -

interphase and M phase.

Explanation:

Cell cycle can be described as a series of events that take place for the division of cell into two daughter cells.

It is primarily divided into two stages, which are-

1) Interphase (that is further divided into G1, S, and G2 phase) that involves the duplication of DNA and other proteins required in cell division.

2) M (mitotic phase) phase during which the nuclear division takes place through four successive stages that are prophase, followed by metaphase, anaphase and telophase.

After this cytokinesis (cytoplasmic division) occurs resulting in formation of two daughter cells.

Thus, first option is the right answer.

Interphase and M phase (Mitotic phase).

Interphase is when the cell is resting and preparing for division, M phase is when the cell is in the process of dividing.

Multicellular organisms arose because _____.

Answers

The answer is because a part of the organism could die and the organism could continue to live. 

In the very changing environment, such was when multicellular organisms evolved, the organisms that could adapt to that environment, survived. If in some moment multicellular organism emerged and its multicellularity helped him to survive, that is the reason this characteristic remained. On of the explanation is that multicellularity allows the organism to continue to live even if a part of the organism dies.

A coelom is _____.an arrangement of organs
a cavity filled with fluid
layers of tissue
an inner lining of tissue

Answers

Option B, a cavity filled with fluid, is the right answer.

A coelom is a fluid-filled mass decay in bilaterally symmetrical mammals that is absolutely filled with derivatives of mesoderm. In simple terms, it is the main body cavity in many animals and is found inside the body to encompass and hold the digestive expanse and different organs. In matured creatures, it is marked with mesothelium and in other mammals like molluscs endures undifferentiated.
