1 answer:
Usimov [2.4K]3 years ago
8 0

Answer:The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass. In a physical change, a substance's physical properties may change, but its chemical makeup does not.

How do veins keep blood moving
GenaCL600 [577]

Answer:

The return of blood to the heart is assisted by the action of the skeletal- muscle pump. As muscles move, they squeeze the veins running through them. Veins contain a series of one-way valves, and they are squeezed, blood is pushed through the valves, which then close to prevent backflow.

A. behavioral isolation is when the plant or animal acts a particular way to attract their counterparts, like mating rituals.

geographic isolation is the natural barrier preventing similar species from interacting. for example, Galapagos Islands are the only home of flightless cormorants because the islands are so far from any other land for them to invade.

Temporal isolation is when two of the same or similar species cannot reproduce as a result of mismatched sexual maturity.

B. the isolation of two frog species by mating call is behavioral isolation.

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.
