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.

What are some benefits of enzyme production in the process of digestion.
Rudik [331]

Answer:

<u><em>definition;</em></u>

enzymes are protein that catalyze speed up the biochemical reactions and are not changed during the reaction . the molecules at which enzyme work  are called <em>substrate </em> and enzymes convert them into  different molecules called products.

<em><u>benefits of enzyme in digestion ;</u></em>

enzyme lower the activation energy in several ways. they may alter the shape of substrate and reduce the requirement of activation energy . enzyme may also  lower activation energy by bringing substrate in correct orientation to react . enzyme break down <em>carbohydrates, lipids and  proteins  </em>which are component of human food .In digestion larger molecules are broken into smaller molecules like amino acids ,simple sugars ,fatty acid ,vitamins ,salts and water to provide to cells.  these molecules are  a part of larger molecules like protein ,polysaccharids  and lipids . enzymes like amylaze, lypase   ,salivary amylase, pepsin ; it is a very strong protein digesting enzyme it is released in its inactive form pepsinogen  which is converted into pepsin with the help of H-C-L  hydrochloric acid it takes part in digestion in stomach

Bacteria and eukarya are thought to have diverged from archaea. <br> a. True <br> b. False
miv72 [106K]
False. The root of the Eukarya is probably within the Archaea, but this was only discovered six months ago. The consensus hasnt yet shifted from thinking the tree of life has three distinct domains. In any case, bacteria are a separate domain to Archaea.
