Our crops depend on insect pollination and the complex biological processes that create soil. We benefit from parks, natural environments, and animals when we do so because it improves our health and wellbeing.
What advantages can the environment provide us in our day-to-day activities?As a society, we rely on healthy ecosystems for a number of purposes, such as crop pollination to ensure that we won't go hungry, air purification so that we can breathe easily, carbon sequestration to control the climate, nutrient cycling so that we can access clean drinking water without having to invest in pricey infrastructure, and so on.
Healthy ecosystems keep our soil in good condition, purify the air, regulate the climate, recycle nutrients, and provide us with food.

plz can i get brainliest:)
Alkali substances has a pH greater than 7 hence it follows that the lye in soap has a pH over 7.
What is corrosion?
The term corrosion has to do with the waering away of a metal surface due to the action of oxidation. Hence the term applicable is corrosion.
The bases are know to be have a bitter taste and are slippery to touch hence the correct response is bases.
Water is a neutral substance, in the pH scale, a neutral substance has a pH of 7 hence the pH of water is 7.
Sulfuric acid is an acid and acids have a pH that is below 7 hence the pH of sulfuric acid is under 7.
Given the fact that alkali substances has a pH greater than 7, it follows that the lye in soap has a pH over 7.

In the late 1980s and early 1990s, the percentage of Icelandic children whose bacterial infections were caused by bacteria resistant to penicillin rose at an alarming rate. After public health officials initiated a campaign to reduce the use of penicillin, resistance dropped off. This observation is consistent with the hypothesis that ________.
Answer:
The correct answer would be - "bacterial populations evolve in response to the selection pressure imposed by antibiotics".
Explanation:
The given information provided in the question about the bacterial infection supports the hypothesis that the bacterial population shows the evolution in response to the selection pressure caused by the antibiotics due to the fact that bacteria increased resistance gradually with time. This resistance towards antibiotics increased the percentage of bacterially infected children in the late 1980s and early 1990s.
In this case, the population of bacteria having resistance genes is selected to evolved selected to increase their offsprings.

the blood speed in a normal segment of a horizontal artery is 0.15 m/s. An abnormal segment of the artery is narrowed by an arteriosclerotic plaque down to one fifth its normal cross sectional area. What is the difference in blood preassures between the normal and constricted segments of the artery. The density of the blood is 1060
Answer:
286.2 pa
Explanation:
Blood speed in a normal segment of a horizontal artery ( v2 ) = 0.15 m/s
Density of blood = 1060 kg/m^3
Normal sectional area = A2
constricted sectional area ( A1 )= 1/5 A2
Determine the difference in blood pressures between the normal and constricted segments
we will apply Equation of continuity Av = constant
Δ p = 12 PV^2
= 12 * 1060 * ( 0.15 )^2
= 12720 * 0.0225 = 286.2 pa

What goes in the blank ?
Answer:
Kilowatt-hour
Explanation:
Energy refers to the amount or quantity of power which is being consumed by an individual, group of people or organization over a specific period of time. As the consumers continue to use energy, they're being charged or made to pay a utility fee regularly for their amount of consumption, which is usually calculated hourly (kilowatts hour or kwh).
Hence, power utility companies use kilowatt-hour (KWh) per month, to determine how much energy is being used.
