Answer:

In addition to biology, evidence drawn from many different disciplines, including chemistry, geology, and mathematics, supports models of the origin of life on Earth. In order to determine when the first forms of life likely formed, the rate of radioactive decay can be used to determine the age of the oldest rocks (see optional problems C and D, below) exposed on Earth’s surface. These are found to be approximately 3.5 billion years old. The age of rocks can be correlated to fossils of the earliest forms of life. A. The graph compares times of divergence from the last common ancestor based on the fossil record with a "molecular time" constructed by comparing sequences of conserved proteins to determine a mutation rate (after Hedges and Kumar, Trends in Genetics, 2003). Explain how such a molecular clock could be refined to infer time or the evolution of prokaryotes. B. Using a molecular clock constructed from 32 conserved proteins, Hedges and colleagues (Battistuzzi et al., BMC Evol. Biol. 2004) estimated the times during which key biological processes evolved. A diagram based on their work is shown. Connect the time of the origin of life inferred from this diagram with the age of the oldest fossil stromatolites and the age of the oldest exposed rock to show how evidence from different scientific disciplines provides support for the concept of evolution. Evaluate the legitimacy of claims drawn from these different disciplines (biology, geology, and mathematics) regarding the origin of life on Earth. The oldest known rocks are exposed at three locations: Greenland, Australia, and Swaziland. The following application of mathematical methods provides essential evidence of the minimum age of Earth.

Answer:

Produce and transport haploid gametes.

Explanation:

The reproductive system is a set of organs used to produce gametes and lead them outside the organism. Thus, this system is responsible for the production of gametes in the body of the animal or human, and in the case of male beings, their transfer to the body of the female in order to fertilize it and give way to reproduction, which is, in short, part of the tasks that every living being instinctively develops at some point in their life. The organs of the reproductive system are distinguished internally and externally. In humans, the external organ is the vagina for women and the penis for men, respectively.

weeeeeb [17]

<span>Agar is known to be a gelatinous polymer substance that was commonly used in the laboratory setting as a substrate. Thus, nutrients agar can grow different types of microbes such as fungi and bacteria while MacConkey agar is made with bile salts and crystal violets, these additives cause the agar to only grow Gram – negative bacteria. However, nutrients agars grow more organisms because it contains nutrients from either beef broth or yeast extracts when compared with MacConkey agar.</span>
