After phosphates and nitrates enter a water system, the steps of eutrophication include the rapid growth of algae, death of underwater plant species, depletion of oxygen in the water, and the death of fishes and invertebrates. The correct option would be B.
Eutrophication refers to the excessive enrichment of water bodies by nutrients such as phosphates and nitrates thereby facilitating the rapid growth of some aquatic species with negative effects.
Once a water body becomes excessively enriched with phosphates and nitrates, the following is a sequence of events that follows:
Algal bloom: the nutrients facilitate the rapid growth of algaeThe bloom of algal species results in the death of underwater plants as a result of inadequate light.The death of the underwater plants and the accompanying microbial activities in decomposing them cause oxygen levels in the water to drop.Reduction in oxygen level causes fishes and other water invertebrates to die due to hypoxiaTherefore, the correct steps of eutrophication according to the illustration is IV, II, I, and III.

Which statement describes the damage that results from earthquakes?
A: Amount of damage can be used to determine intensity.
B: Damage can be measured using the Richter scale.
C: The amount of damage increases as magnitude decreases.
D: Earthquakes that cause maximum damage are the most common.
Answer:
option c is correct
Explanation:
The statement that describes result from the activities of Earthquake is C: : The amount of damage increases as magnitude decreases.
An earthquake can be regarded as outcome of release of stored energy , which is released suddenly into the Earth's crust and as a result of this seismic waves is created.Earthquake do occur by displacement of the ground or by shaking the Earth's surface, Some of other results of earthquakes are;damage to bridgescause tsunamisinitiation of slope failuresloss of life However, as the earthquake is in action and as the damages increase, then there would be a decrease in it's magnitude.Therefore, option C is right because as its magnitude decrease, then the damage will increase.

A student finds that the mass of 25mL of an unknown liquid is 20.5g. What is the density of this substance?
Answer:
Density, [tex]d=0.82\ g/cm^3[/tex]
Explanation:
It is given that,
Mass of unknown liquid is 20.5 kg
Volume, V = 25 mL
We know that, 1 mL = 1 cm³
25 mL = 25 cm³
The density of the substance is equal to its mass per unit volume. So,
[tex]d=\dfrac{m}{V}\\\\d=\dfrac{20.5\ g}{25\ cm^3}\\\\d=0.82\ g/cm^3[/tex]
So, the density of this substance is [tex]0.82\ g/cm^3[/tex].

Without the discovery of magnetic reversals recorded on the ocean floor, scientists
A. could not confirm the usefulness of sonar
B. could destroy the hypothesis of continental drift
C. could not provide a mechanism for moving continents
D. could explain how the seafloor was being destroyed
Answer:
C. could not provide a mechanism for moving continents
Explanation:
Without the discovery of magnetic reversals recorded on the ocean floor, scientists could not provide a mechanism for moving continents.
Magnetic reversals are responsible for geological shifts and depend on the distribution of tectonic plates that causes movements of continents.
Asymmetric movement of tectonic plates leads to movement of continents and the degree of asymmetry varies with the same rythm of the magnetic reversal rate.
Hence, discovery of magnetic reversals are important to identify the mechanism for moving continents.
The study of a living being is called biology.
The correct answer is C.

ASAP What occurs after the homologous pairs are separated?
A. The sister chromatids separate.
B. Spindle fibers attach to the chromosomes.
C. Haploid cells are formed.
D. The nuclear envelope reforms.
Answer:
A
Explanation:
the sister chromatids separate
After the separation of homologous pairs, the sister chromatids are subsequently separated during meiosis II.
What is Homologous pair?Homologous pairs may be defined as those chromosomes which are very identical to one another and have the same size and shape.
In meiosis I, the separation of homologous pairs occurred. After this process, the sister chromatids are separated in meiosis II.
This separation leads to the production of a total of four products having the half number the chromosomes as compared to the original cell.
Therefore, the correct option for this question is A.
