What happens to euglena when sunlight is not present?

Euglena is a genus of eukaryotic unicellular flagellates. Species of Euglena have characteristics of both plants and animals. Euglena have photosynthesizing chloroplasts within their cell which enable them to make their own food in sunlight just like plants. When sunlight is not present, euglena becomes distinctly animal-like. Its cells will absorb food (organic substances) from the environment (heterotrophically).

homeostasis is the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. and this is how it applies to the integumentary system. back to top. skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. when body temperature falls, the sweat glands constrict and sweat production decreases.

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
