katrin2010 [14]

Answer:

Euglena is a single celled organism. It belongs to Kingdom Protista. Euglena is  a eukaryotic organism that exhibit characteristics of both plants and animals. Some species of Euglena are photoautotrophs like plants which means they have ability to trap sunlight to produce food by the process of photosynthesis. Whereas, some species are heterotrophs like animals which means they obtain food by feeding on other organisms.

If scientists remove all of the chloroplasts from a Euglena, it will not be able to perform photosynthesis because chloroplast is an organelle that contains light sensitive pigments named as chlorophyll. Chlorophyll traps light energy from sun. Sunlight energy, along with carbon dioxide and water produces food in the form of glucose in plants and other photoautotrophs.

Joyce is planting tulips in her garden, and she has 5 red bulbs and 5 white bulbs to plant in one row. What is the probability t
Stolb23 [73]

Answer:

\frac{1}{126} or 0.0079.

Explanation:

Joyce is planting tulips in her garden.

Number of red (R) bulbs = 5

Number of white (W) bulbs = 5

Total number of ways to plant 10 bulbs in one row is

\text{Total ways}=\frac{10!}{5!5!}

\text{Total ways}=\frac{10\times 9\times 8\times 7\times 6\times 5!}{5\times 4\times 3\times 2\times 1\times 5!}

Cancel out common factors.

\text{Total ways}=252

It is given that she randomly plants the bulbs so that all 5 red bulbs are next to each other and all 5 white bulbs are next to each other.

Required outcomes are

RRRRRWWWWW and WWWWWRRRRR

\text{Required outcomes}=2

Formula for probability:

Probability=\frac{\text{Required outcomes}}{\text{Total ways}}

Probability=\frac{2}{252}

Probability=\frac{1}{126}

Probability\approx 0.0079

Therefore the required probability is \frac{1}{126} or 0.0079.
