Answer:

The correct option is D

Explanation:

Multicellular organisms are organisms with more than one cell (usually having different cells exhibiting specialized functions). Examples of this organisms are mammals. These organisms generally look for food, <u>eat this food, process/metabolize this food in order to derive nutrients from them</u>. From the explanation above, it is clear that the correct option is D.

Que. 1. Gallium has 2 naturally occuring Isotopes with mass numbers 69 &amp; 71 respectively. What is the percentage abundance o
IgorC [24]

Isotopes are atoms of the same element that have different masses. The relative atomic mass (am) is a weighted average that takes into account the abundance of each isotope. We can calculate the relative atomic mass using the following expression.

am = \frac{\Sigma m_i  \times ab_i}{100}

where,

  • mi: mass of each isotope
  • abi: percent abundance of each isotope

For Gallium,

70.59 amu = \frac{69 amu\ x + 71 amu\ y}{100}     [1]

where "x" and "y" are the unknown abundances.

We also know that the sum of both abundances must be 100%.

x + y = 100

y = 100 - x   [2]

If we replace [2] in [1], we get

70.59 amu = \frac{69 amu\ x + 71 amu\ (100-x)}{100} \\7059 amu = -2 amu\ x + 7100amu \\x = 20.5

Then, in [2]

y = 100 - x = 100 - 20.5 = 79.5

In conclusion, Ga-69 has an abundance of 20.5% and Ga-71 has an abundance of 79.5%.

Slimotosis
Flauer [41]

Answer:

Here's what I get  

Explanation:

A. Initial observation

Gary's shell had slime and an odour.

B. Independent variable

The independent variable is the one that the experimenter changes.

There are two independent variables: the rubbing with seaweed and the drinking of Dr. Kelp.

C. The dependent variable

The dependent variable is the amount of slime and odour.

D. The conclusion

Sponge Bob can conclude that rubbing the shell with seaweed and drinking Dr. Kelp removes the slime and odour.

However, this was a poorly designed experiment. He doesn't know if it is the seaweed or the Dr. Kelp that gives the result or if he must use both together. He should change only one independent variable at a time.
