Is Euglena unicellular?
Answer: yes
Explanation:
Euglena belong to the kingdom Protista, and this kingdom is categorized as unicellular beings.
Answer:
yes
Explanation:
A euglena is a unicellular organism. Explain how the euglena's cell parts help it stay alive.
Explanation:
Euglena are unicellular organisms classified into the Kingdom Protista, and the Phylum Euglenophyta. All euglena have chloroplasts and can make their own food by photosynthesis. They are not completely autotrophic though, euglena can also absorb food from their environment; euglena usually live in quiet ponds or puddles.
Euglena move by a flagellum (plural ‚ flagella), which is a long whip-like structure that acts like a little motor. The flagellum is located on the anterior (front) end, and twirls in such a way as to pull the cell through the water. It is attached at an inward pocket called the reservoir. Color the reservoir grey and the flagellum black.
The Euglena is unique in that it is both heterotrophic (must consume food) and autotrophic (can make its own food). Chloroplasts within the euglena trap sunlight that is used for photosynthesis, and can be seen as several rod like structures throughout the cell. Color the chloroplasts green. Euglena also have an eyespot at the anterior end that detects light, it can be seen near the reservoir. This helps the euglena find bright areas to gather sunlight to make their food. Color the eyespot red.Euglena can also gain nutrients by absorbing them across their cell membrane, hence they become heterotrophic when light is not available, and they cannot photosynthesize.
The euglena has a stiff pellicle outside the cell membrane that helps it keep its shape, though the pellicle is somewhat flexible and some euglena can be observed scrunching up and moving in an inchworm type fashion. Color the pellicle blue.
In the center of the cell is the nucleus, which contains the cell's DNA and controls the cell's activities. The nucleolus can be seen within the nucleus. Color the nucleus purple, and the nucleolus pink.
The interior of the cell contains a jelly-like fluid substance called cytoplasm. Color the cytoplasm light yellow. Toward the posterior of the cell is a star-like structure: the contractile vacuole. This organelle helps the cell remove excess water, and without it the euglena could take in some much water due to osmosis that the cell would explode. Color the contractile vacuole orange.
The cell parts of euglena help it stay alive by the fact that they possess chloroplasts which facilitate them to make their own food by photosynthesis.
What is a Unicellular organism?A unicellular organism may be characterized as a type of organism that significantly consists of a single cell, unlike a multicellular organism that consists of multiple cells. This single cell carries out all of the functions needed by the organism.
Euglena possesses a mixed type mode of nutrition as it can also absorb food from its environment. They move through a flagellum which is a long whip-like structure that acts like a little motor and provides movement.
Chloroplasts within the euglena trap sunlight that is used for photosynthesis, and can be seen as several rod-like structures throughout the cell. In the center of the cell is the nucleus, which contains the cell's DNA and controls the cell's activities.
Therefore, the cell parts of euglena help it stay alive by the fact that they possess chloroplasts which facilitate them to make their own food by photosynthesis.

are the same age?
A. Layers with different fossils
B. Layers of equal density
C. Layers made of the same chemicals
D. Layers with similar fossils
Answer:
D. Layers with similar fossils
Explanation:
Dating consists of ordering geological events according to the time they occurred, which ones occurred first, and which ones occurred latterly. This dating can be done by using the superposition geological principle. This principle states that in a horizontal unperturbed rocky sequence, the oldest layers or stratum are located in the bottom, while the newest ones are more superficially located. Sediments can be incrusted in horizontal layers or stratum. Fossils that are incrusted on these layers represent different ages of the stratum. Different stratum can give us information about the environment in the past. They keep information about the age and the conditions under which the sediments got deposited.
Some geological principles allow us to date, relatively, the age of different geological events in the past.
Sediment layers place in a temporal sequence, let us know that the older layers are located in an inferior position concerning the newer layers. Hence, fossil species placed in more inferior layers are supposed to be older than fossil species found in more superficial layers.
In this sense, those layers or stratum that exhibit the same fossils are believed to be the same age-old.
Classify A large bar of solid gold is melted into liquid. The liquid is then poured into molds to make a number of gold coins. Was this a chemical or physical change?
Answer:
It is still identified as the same substance. In this case, since melting the gold bar is a change that takes place when the solid turns into a liquid, it undergoes a physical change.
Explanation:
This is a physical change. When solid gold melts into a liquid and is poured it will be a physical change.
What is a physical change?There are two types of changes such as physical change and chemical change. In a physical change, there is no change in molecular composition.
In chemical changes, the molecular composition of a substance will change. When gold is turned into a liquid it will melt. This is called a physical change.
In a physical change, the chemical composition of a substance remains the same. The atoms rearrange themselves in physical change.
Therefore, This is a physical change. When solid gold melts into a liquid and is poured it will be a physical change.

How are DNA and RNA related to proteins
Functionally, RNA utilises the protein-encoding information to enable the cell to produce the specific protein, whereas DNA preserves the information.
What is protein synthesis?The process through which cells create proteins is referred to as protein synthesis. The first step is transcription, and then the second step is translation. The process of moving genetic instructions from DNA to messenger RNA (mRNA) in the nucleus of a cell is referred to as transcription. Initiation, elongation, and culmination are the three stages that make up this process.
In a functional sense, DNA is responsible for maintaining the information that codes for proteins, whereas RNA is responsible for putting that information to use in order to permit the cell to synthesize the specific protein.
