Phycobiliproteins are a complex of accessory pigments and proteins found in cyanobacteria but not in green algae. A researcher c

laims that the phycobiliprotein pigments in cyanobacteria allow the cyanobacteria to survive in certain aquatic niches better than green algae can.
Which of the following statements best justifies the researcher’s claim?

A. The additional pigments allow the cyanobacteria to store light energy so that it can be used at night to continue photosynthesis.

B. The additional pigments block light and prevent it from reaching photosynthetic organisms at greater depths, so no photosynthetic organisms can live below the surface waters containing cyanobacteria.

C. The additional pigments require energy and cellular resources to produce, so they can be used as an energy source during times of insufficient light.

D. The additional pigments absorb light at wavelengths that green algae cannot absorb; this may allow cyanobacteria to capture more light energy for photosynthesis than green algae can in certain areas.

Answer:

Option D

Explanation:

Cyanobacteria preserve its photosynthetic pigments in the thylakoids which allows masking of green of chlorophyll a and other accessory pigment i.e phycobiliproteins (phycocyanin, allophycocyanin and phycoerythrin).  

Chlorophyll a is mainly responsible for harvesting light for photosynthesis. Phycocyanin is blue in color, allophycocyanin is blue in color  and phycoerythrine is red in color. These together harvest light in the green, yellow and orange part of the spectrum which cannot be used by other phytoplankton species

Hence, option D is correct

How many kinds of gametes will be expected from an individual with the genotype ppccttrr?
ElenaW [278]

<u>Answer:</u>

<em>16 kinds of gametes can be expected from an individual with the genotype ppccttrr. </em>

<u>Explanation:</u>

<em>Gametes are the haploid mature germ cells which can be both male and female.</em> They have the ability to unite to opposite sex in the reproduction phase to form a zygote.

<em>The example of gamete is the sperm that is ready to fertilize the egg during reproduction. </em>so there will be 16 types of reproductive cell with single <em>set of unpaired chromosomes with the genotype ppccttrr.</em>

To help explain surface tension, use a single water molecule in the template, and draw arrows representing the possible location
kramer

Answer:

The correct representation is attached with the explanation.

Explanation:

In this representation of the surface tension, blue arrows between green water molecules are the possible molecules that can be used as the location for forming hydrogen bonds by a single molecule. Surface tension is the tendency of a liquid surface strectch to neighbouring molecules or ability to shrink in minimum surface area possible. Hydrogen bonds is an intermolecular force or interaction responsible for the surface are of liquide molecules. This bonds is towards every direction where the similar molecule present.
