An individual with androgen insensitivity syndrome will:
A. Not be feminized at puberty
B. Prefer a female sexual partner
C. Not function sexually as an adult
D. Have female external genitalia
Answer:
D I think. i am not completely sure.
An individual with androgen insensitivity syndrome will have female external genitalia, which is option D, as androgen insensitivity syndrome (AIS) is a genetic condition in which an individual's cells are unable to respond to androgens.
What is androgen insensitivity syndrome?Androgen insensitivity syndrome (AIS) is a genetic disorder in which an individual's body is unable to respond properly to male sex hormones, called androgens. The condition is caused by mutations in the gene that codes for the androgen receptor, which is a protein that binds to androgens and enables them to activate certain genes. In individuals with AIS, the androgen receptor either doesn't work at all or doesn't work properly, which leads to a range of physical changes that can vary in severity depending on the degree of androgen insensitivity.
Hence, An individual with androgen insensitivity syndrome will have female external genitalia, which is option D.

Is phrenology an example of science or
pseudoscience? Explain your answer.
Answer:
Pseudoscience
Explanation:
Phrenology is an example of pseudoscience. It is the belief that studying the conformation of the skull reveals the character traits and mental faculties of an individual, a conclusion not at all rooted in fact but nevertheless studied and pursued as such thereby giving a false sense of being based in scientific methods.
Answer:
Pseudoscience
Explanation:
Phrenology is an example of pseudoscience because Gall held beliefs and ignored any information that didn't align with his beliefs. This is a direct example of Gall using pseudoscience and testing his hypothesis with bias through his belief.

Fracking uses highly pressurized fluids, such as water mixed with sand and chemicals, to drive open cracks that exist in underground rock. Which statement
best describes an environmental consequence of this process for ecosystems?
O Wastewater is contaminated with oil and becomes sludge in landfills
O Water vapor is released into the air, which is considered a greenhouse gas,
Heavy metals are released into surrounding soil, poisoning local vegetation
O Billions of gallons of water are pulled from surrounding areas
The correct answer is that chemicals added to the liquid can contaminate groundwater.
Fracking is a method of drilling fossil energy resources, which requires a lot of water and consumes local water resources. It is pumped with high pressure water, sand and chemicals, causing high pressure to block the porous rock and release gas.
The water spill itself destroys nature from the drilling site, and may even cause earthquakes, especially due to the pumping of abundant wastewater into porous rock types such as limestone. For example, Oklahoma appears to have become a special earthquake risk area. The biggest impact of water distortion is on groundwater. In Wyoming, USA, the same chemicals found in groundwater have been found in groundwater, and some of them are toxic or carcinogenic.

________________________ happen when pairs of bonded bases in a double strand of DNA get replaced with different pairs.
_________________________ happen when extra base pairs are included in an existing DNA sequence.
_________________________ happen when base pairs in an existing DNA molecule get removed from it.
Fill in the blanks correctly
Answer:
Explanation:
A base pair is two chemical bases bonded to one another forming a "rung of the DNA ladder." The DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.
