It depends on what you believe. Many Evolutionists would say D. But if you believe in the Bible, then the answer is C.

Prior to the advent of multiplex genetic testing, a person would have been most likely to have a genetic test to determine if th
Sloan [31]

Answer: Colon cancer

Explanation:

All cancers, but especially colon and rectal cancers, commonly referred to as colorectal cancer (CRC), have hereditary factors that potentially increase one’s risk.

Genetic testing is determine if there is an increased risk of colon cancer. Apolipoprotein E (apoE) plays a major role in the metabolism of bile acids, cholesterol and triglycerides, and has recently been proposed as being involved in the carcinogenic process. Given the potential role of bile acids in colorectal cancer etiology, it is reasonable that colorectal cancer risk might be modified by apoE genotype. The absence of an e3 apoE allele significantly increased the risk of colon cancer especially for individuals above 50years.

A woman who is a carrier for colour blindness (X-linked recessive) has children with a man who has normal colour vision. A. What
viva [34]

Answer:

Explanation:

The Genotype of the  woman is XCbXN

The man XNY

Since the allele for the color blindness is carried on one of the X -chromosomes of the  carrier mother, then  the male children will be color blind or carrier deopending on the defective gene they inherited. Since they will receive the defective or normal  allele from the  mothers,but the female will carriers or normal because they will inherit either defective allele or normal allele from the mother,but normal  X allele from the father.

Assuming the colorbind gene was inherited by One of the boys, and the girls take the defective genes

1. XNY vs XCbXN.Then the one of the  boys will be colorblind  and the one of  girls will be carriers. XNXCb, XNXN, XCbY,XNY  50 %

2.If the two boys take the effective genes from the mothers. and none of the girls take the defective alelle

Then the two boys will be colorblind and the girls will be carrries XcbY,XcbY and XNXN XNXN.(normal girls).

The proportions that will be  the females  since the girls can only take the defective allele from one of the normal and defective allele from the mother. Assuming the girls  take the defective allele from the mothers and take normal from the father,they will all  be carriers,since the X of the father is normal.

They can not have a color blind girl.Since the father is normal It takes two colorblind X-chromosome to give a girl.

What environmental worldview is seen by critics as focused on short-term economic benefits with little regard for long term harm
attashe74 [19]
I believe the answer is the global free-market approach.
It is because on continually increasing use of earth's natural capital, and it focuses on short term economic benefits with little regard for degradation and depletion of natural capital and resulting long-term harmful environmental, health, and social consequences. Environmental world views are the ways of thinking about how the world work and beliefs that people hold about their roles in the natural world, another factor is widespread lack of understanding of how earth's life-support system works, keeps us alive, and supports economies.
