Answer:
Abnormal BRCA1 and BRCA2 genes are found in 5% to 10% of all breast cancer cases in the United States. A study found that women with an abnormal BRCA1 gene had a worse prognosis than women with an abnormal BRCA2 gene 5 years after diagnosis.

Answer: False
Explanation: Pitch does not depend on how fast or slow an object vibrates.
The evolution of the peppered moth evolutionary instance of directional colour change in the moth population as a consequence of air pollution during the Industrial revolution .The frequency of dark-coloured moths increased at that time, an example of industrial mellaniam. Later, when pollution was reduced, the light-coloured form again predominated. Industrial melanism in the peppered moth was an early test of Charles Darwin natural selection in action, and remains as a classic example in the teaching of evolution.

Answer:</h3>
Enzymes functions in a specific temperature range.
<h3>
Explanation:</h3>
- Enzymes are biochemical catalysts whose function is to speed up the rate at which chemical reactions occur.
- Enzymes work best at a specific range of temperatures known as optimum temperature.
- Low temperatures below optimum levels deactivate the enzyme and thus lowering the rate of enzyme activity.
- Extreme temperatures, on the other hand, denatures the enzyme altering enzyme's active sites making it difficult for substrates to fit.
Answer:
The correct answer is option D, that is regular or uniform.
Explanation:
The individuals in a population can be spaced in a distinct manner known as the dispersion patterns. The most common arrangement is the clumped dispersion in which these individuals are clustered together. In random dispersion, the individuals are aligned randomly, and in uniform or regular dispersion, the individuals are spaced evenly.
The given case is an illustration of regular or uniform distribution. It is less common in comparison to clumped distribution. The pattern of uniform or regular distribution is witnessed in the populations of the species in which the distance between the adjacent individuals is enhanced. The requirement to enhance or increase the space between the individuals usually originates due to competition for a resource like nutrients or moisture.
