The answer would be: True

Forest ecosystem has a high density of plants. When an infectious plant disease appears, it will be easily spread as the trees are placed close to each other. You could say that the spreading mechanism of wildfire is similar to the disease because it is easier in the high-density area.

Answer:True.

Explanation: The wildfires has many positive aspects as compared to its negative ones. The forest fire can be a result of human activities or it can be due to natural sources.

The forest fire helps in removing the soil contamination and hence prevents the plant disease. Though it eradicated the animals and loss of habitat takes place but besides this there are many more advantages of forest fire.

It helps in removal of the diseased plants and harmful insects that spreads diseases.

The substance dichlorophenyldimethylurea (DCMUDCMU) is an herbicide that inhibits photosynthesis by blocking electron transfer b
mario62 [17]

Answer:

No

Explanation:

During cyclic photophosphorylation, electrons are cycled continuously out of and back into the reaction center of PSI. It does not involve PSII and plastoquinone. During non cyclic photophosphorylation, the reaction center of plant photosystem II passes electrons to plastoquinone. The reduced plastoquinone carries electrons to the cytochrome b6f complex. Since PSII and plastoquinones are not included in cyclic photophosphorylation, dichlorophenyldimethylurea would not affect the process.

Does anyone know this??

Bauxite ore is one of the primary source of aluminum but it must first be chemically processed to produce alumina (aluminum oxide). The next step of aluminum production is smelting of alumina using an electrolysis process (Hall-Heroult process). This electrolysis process is driven by electrical current. Electrolyte (molten salt) with immersed carbon anodes is used in order to dissolve the alumina. Carbon anodes are carrying electrical current and thee chemical bond between aluminum and oxygen in the alumina is broken.

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.
