Answer
Cellular theories of aging
The theoretical perspective that cross-linking represent is the cellular theorie of aging.
Explanation;
Cellular theories of aging are theories of aging that focuses on processes that occur within individual cells. One theory is the buildup of harmful substances in cells over one's lifetime. Another is a limit on the number of times cells can divide, possibly caused by the shortening of the telomeres.
The inheritance of colorblindness gene is X linked. Sally is a female, she'll have two copies of X chromosomes. Since she is not colorblind indicates that she is a carrier of the gene, the presence of at least one functional gene on either of the X chromosome in Sally prevented colorblindness in her. The chances that her husband will have a colorblind child is 25% (1:3) and 50% for the colorblind son (1:1),based on the solved punnett square in the image, where X' denotes the colorblindness gene.
I think it’s either B or C but I’m not sure
A "universal genetic code" is best interpreted as the organic molecular information system that is part of every and all living organisms, most fundamentally within DNA, but having additionally coded elements in other assemblies within the cell.
The complexity and detailed coding of DNA is greater than any existing in any human designed entity, making DNA the logical product of a highly intelligent creator, especially when combined with all of the other detailed elements of a living organism.
There are no naturalistic processes capable of producing anything similar. To prove this, imagine you walk outside and find your name spelled out with small stones in the driveway. You will immediately, absolutely know that some intelligent being spelled it. Now realize that the simplest known organism contains over 1 million coded organic molecules sequenced precisely to encode the proteins and other components within the cell.
As a result, the only rational, logical conclusion for the origin of life is through the utilization of a universal genetic code created by an intelligent designer.
