If you flip a penny 99 times and each time it came up heads then the chance of the penny coming up heads is ___

Biology

Helga [31]3 years ago

The chances of heads as a result when flipping a penny will always be 50%. Although heads came up 99 times in a row, the events that occurred before will not affect the probability of the current event in terms of a coin flip.

There are 1 out of 2 chances of it occurring or 1/2. Divide that and multiply it by 100% to get the probability in percent. So the answer will be 50%.

The answer is B.

True or false: during stressful events, there is decreased blood supply to the skin, which results in "goose bumps."
Sonbull [250]
False.
In a stressful event, there will be a hormone released to the blood called adrenaline. Adrenaline hormone can prepare the body for fight or flight response. One of the effects of this hormone is making the muscle around hair called musculus arrector pili contracted. This contraction of the muscle is what causing the goosebumps. The decreased blood supply has no role in this event.

A purebred tall pea plant is cross-pollinated with a tall, heterozygous pea plant. Use a Punnett square to determine the probabi
Ray Of Light [21]

Answer:

0%

Explanation:

This question involves a gene coding for height in pea plants. The allele for tallness (T) is dominant over the allele for shortness (t). This means that allele T will be expressed over allele t in an heterozygous state.

A purebred tall plant will possess genotype: TT while a heterozygous tall plant will possess genotype: Tt. The two parents will produce the following gametes:

TT- T and T

Tt- T and t

Using these gametes in a punnet square (see attached image), the following offsprings with genotypes: TT and Tt in a ratio 1:1 will be produced.

TT offsprings are purebreed tall while Tt offsprings are heterozygous tall. Hence, based on the question, no offsprings of this cross will possess the recessive genotype (tt). This means that 0% of the offsprings of this cross will be short.
