Answer:

Chloroplast

Explanation: Chloroplasts are the site of photosynthesis, and thus, must contain the chlorophyll a pigment. Additionally, part of the reason they're called "chloroplasts" is because of the presence of the chlorophyll a pigment!

Answer:

A scenario where a cell may be needed to perform a form of endocytosis is when transporting large molecules. A scenario where a cell may be needed to perform a form of exocytosis is when releasing the large molecule from the cell.

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.

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.

Explanation:

When fossil fuels are burned, they release carbon dioxide and other greenhouse gases, which in turn trap heat in our atmosphere, making them the primary contributors to global warming and climate change.

Answer:

The burning of fossil fuels releases carbon dioxide and other greenhouse gases.

Explanation:

Greenhouse gasses can cause climate change by trapping heat, and also contribute to respiratory disease from smog and air pollution.

Answer:

petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both intense heat and pressure.

AnswerDuring breathing, air travels from your mouth and pharynx into the larynx (toward your lungs). When you swallow, a flap called the epiglottis moves to block the entrance of food particles into your larynx and lungs. The muscles of the larynx pull upward to assist with this movement.:

Explanation:

Functionally, RNA utilises the protein-encoding information to enable the cell to produce the specific protein, whereas DNA preserves the information.

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.

Answer:

The correct answer is : decreases

Explanation:

The development of the peppered moth is a transformative event of directional color change in the moth populace as a result of air contamination during the Industrial Revolution.

The melanic or dark color type of the peppered moth was not known before pollution level was low before 1811. Hence the decrease in pollution level in atmosphere will lowers the frequency of the melanic form of peppered moths.

Thus, the correct answer is : decreases.
