3.What is the difference between a dominant and a recessive trait?

Andreyy89

Answer:

Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive.

Sound waves travel through gas liquid and solids A) True B) False

Novay_Z [31]

Answer:

True.

Explanation:

Sound is a form of Energy that produces a sensation of hearing in our ears.
Sound is produced as a result of vibration produced in a body.
Sound energy is transmitted from one place o other place by wave motion.
When a body vibrates, the particles of medium surrounding it starts vibrating about their mean position.
During vibration, they collide with the surrounding particle and transfer some energy to them.
They then start vibrating faster and transferring energy to the next surrounding particle. This process continues till the vibration reaches a person ear.
Thus, particles are an important factor in propagation of sound.
Sound cannot travel in vacuum.
It requires a medium to travel from one point to another.
A sound can travel in all medium, solids, liquids and gases as all of these have particles.
The speed of sound is highest in solids and lowest in gases as the inter molecular space is largest in gases and smallest in solids.

Newsweek in 1989 reported that 60% of young children have blood lead levels that could impair their neurological development. As

Kamila [148]

Answer:

The answer is 83.38%.

Explanation:

The probability of young children having blood levels that impair their neurological development is given as 60% in the question. To find the probability of at least 5 children out of 10 in a sample having said blood levels, we need to use the binomial probability.

n represents the total number of children in the sample so n = 10 and p is the probability of the children having blood levels causing the problem which is 60% so p = 0.6.

We want the probability of it being observed for 5 or more children and that is $P(x\geq 5)$ . If we subtract the $P( x\leq 4)$ from 1, which is the probability of not observing the condition in 5 or more children, we will have the $P(x\geq 5)$ .

$1 - P(x\leq 4) = 1 - pbinom(4, 10, 0.6)$ which are the probability range in the function, the sample size and the probability of observing the condition respectively.

The result is 1 - 0.1662 = 0.8338 which means that the probability that is asked is 83.38%.

I hope this answer helps.
