Based on the data shown in the graph, when would the species richness of the ecosystem have been the lowest?

1 answer:

Hello. The graph to which this question refers, shows that after a volcanic eruption there is a decrease in the number of species of plants and animals in the region, in between this number begins to grow as time progresses.

Answer:

According to the data, the species richness in an ecosystem is lower one year after the volcanic eruption.

Explanation:

The volcanic eruption has the capacity to decimate many species of plants, as well as species of animals, which decreases the richness of species in this ecosystem. However, the year following the volcanic eruption presents an even smaller species risk, since many species are unable to readapt to the new environment, thus undergoing a process of natural selection. As this adaptation progresses, the number of species will grow periodically, making the species richness greater in the ecosystem in four years.

Acetone is a flammable solvent used in the making of plastics. The density is 790kg/m3 to g/cm3 , 1,000 and , 10^6 these operati

Answer: 0.790 g/cm3

Explanation:

The density of acetone is 790 Kg/m3.

To convert from Kg to g we multiply by 1000 (1 Kg = 1000 g)

To convert from m3 to cm3 we multiply by 10∧6

So, The density of acetone in (g/cm3) = (790 x 1000) / (10∧6) = 0.79 g/cm3

The Assessment Test asked, "Do I feel disappointed when my achievements go unnoticed?" Do I Agree or Disagree?

Romashka [77]

I would disagree.
It is not always important to be noticed, because you don't have to depend on other people's approval. If you are satisfied with your accomplishments, why does it matter if someone else is going to praise you for them or not? You should be happy, regardless of other people's opinions and thoughts.

Particle x moves along the positive x-axis so that its position at time t ~ 0 is given by x(t) = 5t 3 - 9t 2 + 7. at what time t

Arada [10]

Answer: 1.2 seconds

Explanation:

$At the farthest point the velocity of particle will be zero. \ Differentiating the given equation of position and equating it with zero:$$\begin{aligned}x(t) &=5 t^{3}-9 t^{2}+7 \\x^{\prime}(t) &=15 t^{2}-18 t \\0 &=15 t^{2}-18 t \\t(15 t-18) &=0 \\t &=0 \\t &=\frac{18}{15}=1.2 \mathrm{~s}\end{aligned}$

$$$Thus, at $t=1.2 \mathrm{~s}$ particle will be at the farthest point. \\\\\underline{Justification:}\\The particle moves towards the left from $t \in[0,1.2)$. After that particle keeps moving in the positive x-direction.$
