Answer: The correct answer is- D certain factors are dominant and other factors are recessive.
Mendel was interested in knowing the offspring that is produced from the cross pollination (that is from two different plants) as he wanted to study different traits of pea plant.
For doing so, he first removed the anthers of one plant (to prevent self pollination) and then transferred the pollens of one plant into the stigma of another plant.
When he allowed the cross pollination of purebred pea plant with other plant, he observed that some factors are dominant (such as tall height of pea plant, which masks the expression of recessive factors) and other are recessive (such as dwarf height of pea plant).
Thus, option D) is the right answer.
Answer: Potassium-40 decays into argon gas over time.
Explanation: Potassium-argon dating is a dating method used to determine the age of sedimentary rocks by comparing the proportion of K-40 to Ar-40 in a sample of rock, and knowing the decay rate of K-40.
Potassium-40 undergoes decay following first order kinetics as given below:

Water helps your body maintain your body functions and regulates the temperature of your body and you lose water by doing activities by running, sweating and digesting its important to high drat all the time. Its important and re hydrate and eat food that have water in them like apples is an example.
Hello. This question is incomplete. The full question is:
In 10th grade , Natalie fits the societal ideal of a slender body type . She is most likely a(n) :
A) late-maturer.
B) average-maturer.
C) prepubescent.
D) early-maturer.
Answer:
D) early-maturer.
Explanation:
If Natalie is in 10th grade, it means she is around 15-16 years old. This is an age when the body is being modeled after the molds of an adult body. However, children's characteristics should still be present at this age.
This is not what is happening to Natalie, since at this age she has a body that fits society's standards for a slim body. These standards of beauty in society are aimed at adult bodies, Natalie is not an adult, which shows that she is a person with early maturity.
Answer:
The density of water increases as the salinity increases. The density of seawater (salinity greater than 24.7) increases as temperature decreases at all temperatures above the freezing point. The density of seawater is increased by increasing pressure.
