Biology

MrRissso [65]3 years ago

<span>Because of the difference in materials and the compression of gravity at depth, the inner core is the highest density. The lowest is the crust which is basically floating on the mantle. While no one has drilled that far, the basic assumption from magnetism and pieces of other planets delivered as meteors is that the inner material is iron, nickel and other heavy magnetic elements along with heavy radioactive elements.

The final answer to your question is C. core.

I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

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.

Which characteristic of living things is important to the survival of a group of animals rather than an individual member of thi
mash [69]

Answer:

If a whole specie of organisms has to survive, they should must possess the ability to reproduce and adopt to environmental conditions in better way.

For example: If a disaster occurs or a condition of unfavorable weather occurs, the specie will survive even if only few members remain alive. Because those members will reproduce and regrow the community.

The reason is this that reproduction is not important for the survival of one organism, like organism will still survive even if he do not reproduce, but if a whole specie has to survive and continue, reproduction is most important trait.

Hope it help!
