Euglena move from one place to another like an animal. When they manufacture their own food, they have to move to such an area where they can receive required amount of sunlight. There are two features on its body that facilitate in its movement. The most important is the flagellum, which is a long whip-like appendage attached to the body. It turns and twists in the water in order to push the body through the water. The other physical feature that plays a vital role in giving a sense of direction to its movement is the eyespot, also located at the anterior of its body. It is a light-sensitive, pigmented organelle which is capable of detecting sunlight. Thus, it orients the movement towards the direction of light, where they can collect sunlight required for making food.The ability to move plays a significant role in vital life processes of Euglena, such as the synthesis of food. Hope that helps ;)
The answer would be TIA
Transient Ischemic Attack or TIA is a <span>sudden deficient supply of blood to the brain lasting a short time. This will cause the loss or reduction of function of the affected brain area. The symptoms should disappear <24 hours to have it diagnosed as TIA. If the symptoms persist >24 hours, the diagnosis would be RIND or stroke.</span>

B and C)
They often obtain most of their nutrients through the cell membrane as diffusion is able to take place passively and so at no energy loss to the organism, this can be essential for a single celled organism as they are able to produce a lot less energy due to having fewer mitochondria in comparison to multicellular organisms.
They also require few resources as single celled organisms are very small and so require only a small amount of raw resources for respiration because they have a small energy demand to meet.
Answer:
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
Cancel out common factors.
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
Formula for probability:
Therefore the required probability is or 0.0079.
