Describe the founder effect.
The founder effect is the loss of genetic variety that happens when a new population is founded by a small number of individuals from a larger population, according to population genetics. Ernst Mayr was the first to thoroughly explain it in 1942, based on previous theoretical work by people like Sewall Wright.

Which term refers to the energy an object has due to its position? A Electrical energy B. Potential energy C. Thermal energy D. Kinetic energy
Answer:
Option B
Explanation:
Using the process of elimination, we will find this answer.
It's not option A because electrical energy involves electricity and has nothing to do with motion/position, although you can build machines fueled on electrical energy to create motion or position. (Hence; vehicles)
It is option B because potential energy is energy the object has when it's at rest, which means when the object remains in the same position it has potential energy.
It's not option C because thermal energy involves heat which you could use heat energy and convert it into electrical and then build a machine that is fueled on electrical energy that creates motion or position. (Hence; boats)
It's not option D because Kinetic energy is purely energy when a object is in motion, has nothing to do with a position of a object. As long as the object is moving it has kinetic energy.
Your answer is option B or "potential energy."
Hope this helps.

What is the missing word? If an enzyme is heated to a temperature of 50 °C it stops working permanently. The enzyme is said to have become what?
When a protein is subjected to unusual environmental circumstances, it undergoes denaturation, which is a physical change. Proteins can be denatured by heat, acid, strong acids, alcohol, mechanical agitation, and high salt concentrations.
What are the main cause of enzyme denaturation?pH and temperature. When an organism is at its ideal temperature, enzymes work best. This temperature in the human body is 37 °C. Only up to a certain degree do enzyme activity and reaction rates rise slightly with temperature.

Answer:
C.
They find a sudden disappearance of many fossil species.
Explanation:
A mass extinction is usually defined as a loss of about three quarters of all species in existence across the entire Earth over a “short” geological period of time. Given the vast amount of time since life first evolved on the planet, “short” is defined as anything less than 2.8 million years.
if sally marries a man who is an asymptomatic carrier for alkaptonuria, what is the probability that they would have a son with alkaptonuria
Alkaptonuria is passed down through the generations as an autosomal recessive condition. When an individual receives the same faulty gene for the same trait from both parents, they are said to have recessive genetic diseases. If a person is born with one normal gene and one illness gene, he or she will be a carrier for the disease but will not display symptoms. With each pregnancy, there is a 25% chance that two carrier parents will both carry the faulty gene and, as a result, have an afflicted child. With each pregnancy, there is a 50% chance of having a child who is a carrier like the parents. A child's chance of receiving normal genes from both parents and being genetically normal for that attribute is 25%.
