Answer:

chlorophyll

Explanation:

Most plants contain a special colored chemical or pigment called chlorophyll that is used in photosynthesis. Chlorophyll is what absorbs the sun's energy and turns it into chemical energy. Not all the light energy from the sun is absorbed. Sunlight has many different colors in it.

Elden [556K]

The answer is C. This is because the other choices involve experiences (most during childhood a significant phase in humans development) that are environmental factors that impact on the human personality. In choice C, there is little development since its adulthood phase and on the other hand, refusing to display warmth and emotion is not an experience.

Alexandra [31]

Answer:

Nitrgen Cycle

Explanation:

Animal waste includes nitrogen that passes through the nitrogen cycle, these steps summarise into:

The nitrogen cycle moves nitrogen back and forth between the atmosphere and organisms.

Bacteria change nitrogen gas from the atmosphere to nitrogen compounds that plants can absorb.

Other bacteria change nitrogen compounds back to nitrogen gas, which re-enters the atmosphere.

Yeast cells are recovered from a fermentation broth by using a tubular centrifuge. Sixty percent of the cells are recovered at a

Serga [27]

Answer:

$\\ \omega = 5033.22 \ rpm$

Explanation:

Given that:

$R_1 = 0.6\\\\R_2 = 0.95\\\\\omega_1 = 4000 \ rpm\\\\\omega_2 = ???\\\\Q_1 = 12\ l/min\\\\Q_2 = 12\ l/min$

For a continuous centrifuge ; solid recovery R ∝ $\frac{\omega^2}{Q}$

where;

ω = angular velocity of the centrifuge in rpm

Q = flow rate

SO;

$R_1 \alpha \frac{4000^2}{12}$

$R_2 \alpha \frac{\omega^2}{12}$

$\frac{R_1}{R_2} = \frac{4000^2}{12}$ ÷ $\frac{\omega^2 }{12}$

$\frac{R_1}{R_2} = \frac{4000^2}{12} * \frac{12}{\omega^2}$

$\frac{R_1}{R_2} = \frac{4000^2}{\omega^2}\\\\\frac{0.6}{0.95} = \frac{4000^2}{\omega^2}$

${\omega^2} = \frac{4000^2*0.95}{0.6}\\\\\\{\omega} = \sqrt{ \frac{4000^2*0.95}{0.6}}\\\\\\ \omega = 5033.22 \ rpm$

Which is the first type of cell to differentiate?

Strike441 [17]

I think the correct answer from the choices listed above is option A. The first type of cell to differentiate is a neuron. The neurons are cells that process and transmits information through electrical and chemical signals. Hope this answers the question.
