<u>Answer:</u> The correct answer is Option B.

<u>Explanation:</u>

For the given options:

<u>Option A:</u> Autotrophic organisms are defined as the organisms which produce  their own food for survival. For Example: Green plants

<u>Option B:</u> Prokaryotic organisms are a unicellcular organisms which lack a membrane bound organelles like mitochondria, nucleus etc.. For Example: Bacteria.

<u>Option C:</u> Eukaryotic organisms are multicellcular organisms which have membrane bound organelles like mitochondria, nucleus etc.. For Example: Human beings.

<u>Option D:</u> Heterotrophic organisms are defined as the organisms which do not produce their own food. For Example: Tigers, Lions etc..

Hence, the correct answer is Option B.

While visiting the planet Mars, Moe leaps straight up off the surface of the Martian ground with an initial velocity of 105 m/s
yawa3891 [41]

Answer:

L = 0 m

Therefore, the cricket was 0m off the ground when it became Moe’s lunch.

Explanation:

Let L represent Moe's height during the leap.

Moe's velocity v at any point in time during the leap is;

v = dL/dt = u - gt .......1

Where;

u = it's initial speed

g = acceleration due to gravity on Mars

t = time

The determine how far the cricket was off the ground when it became Moe’s lunch.

We need to integrate equation 1 with respect to t

L = ∫dL/dt = ∫( u - gt)

L = ut - 0.5gt^2 + L₀

Where;

L₀ = Moe's initial height = 0

u = 105m/s

t = 56 s

g = 3.75 m/s^2

Substituting the values, we have;

L = (105×56) -(0.5×3.75×56^2) + 0

L = 0 m

Therefore, the cricket was 0m off the ground when it became Moe’s lunch.

A scientist is studying a cell and can clearly see that it has ribosomes and mitochondria. Which statement best describes how th
Svet_ta [14]
The correct answer here is that the cell would most likely be classified as a eukaryotic cell. This can be determined due to the fact that there are membrane-bound organelles within the cell, so we know that this is a eukaryotic cell rather than a prokaryotic cell because because organelles are not needed within prokaryotic cells.
