Which type of cells are being
displayed?

Euglena are unicellular organisms classified into the Kingdom Protista, and the Phylum Euglenophyte. 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.

Answer:

The colony of bacteria is called cit positive, or cit in case these advance with colonization in media with citrate, since if they grow in number and proliferate, it means that they use citrate as a metabolite or food resource for their metabolism.

Explanation:

In case these are negative cit, the profileration would have to be null or see that the colony stagnant its growth, that is to say that they did not increase in number or even decrease their number layers and they did not replicate in media with citrate.

The colony of bacteria is named cit positive, or cit just in case these advance with colonization in media with citrate.

Since if they grow in number and proliferate, it means they use citrate as a metabolite or food resource for metabolism.

In case these are negative cit, the proliferation would have to be null or see that the colony stagnant its growth, that is to say, that they did not increase in number or maybe decrease their number layers and that they didn't replicate in media with citrate.

E. coli, a species of bacteria that lives harmlessly in every person’s gut by the billions. A typical E. coli contains about 4,000 genes (we have about 20,000). Feeding on sugar, the microbe grows till it's able to split in two.

It makes two copies of its genome, nearly always managing to supply perfect copies of the first. The single microbe splits in two, and every new E. coli receives one of the identical genomes. These two bacteria are, in other words, clones.

Therefore, E.coli grows in presence of citrate that evolved in the population of 30,000 generations.

Answer:

A complex food web is better than the simple food chain because the food web links together the relationships between a producer, consumer, and decomposers. Another reason why a complex food web is better than a simple food chain is that if a particular species is eliminated from a food web, the entire ecosystem has a lower chance of collapsing due to that loss. A food web can more readily react to changes in the environment that impact one or more species.

Hope this helps :)

Answer:

(Answers may vary.)

A complex food web is more important than a simple food chain for the survival of a community. The food web is more important because it is more intricate and adaptive than a food chain. A community houses many species. These species are dependent on each other for energy and food. So, there are multiple relationships of energy transfer involved.

A food chain is linear, which means that each predator has only one source of food. So the predator is vulnerable if the food source is depleted through disease or a change in environmental conditions. Whereas in a food web, each predator has many food sources. A complex food web provides multiple preys to species at a higher trophic level. As a result, a food web illustrates the feeding relationships between many species at different trophic levels in an ecosystem.

Answer:INTERSPECIFIC COMPETITION

Explanation:

The physical factor that determines the number of organisms in a population is ;   Interspecific competition

Interspecific competition in a population is a competition that exists between organisms of different species, while the competition that occurs within organisms of the same specie is termed intraspecific competition.

During Interspecific competition the different species compete for food, water and Habitat which every organism needs to survive, and in most cases the stronger specie overruns the weaker species and this will lead to the depletion in the number of the organisms of the weaker specie and an increase in the number of the stronger specie within the population.

Hence we can conclude that The physical factor that determines the number of organisms in a population is ; Interspecific competition .

phospholipid

Explanation:

Phospholipids, triglycerides, fats, and oils are examples of a lipid. Therefore, option D is correct.

Fatty, waxy, or oily molecules are referred to as lipids. They are soluble in organic solvents but insoluble in polar solvents like water. Steroids, phospholipids, oils, and waxes are examples of lipids. They are usually referred to as fats and oils.

Since lipids may be broken down to provide significant amounts of energy, one of their primary biological purposes is the storage of energy. The structural elements of cell membranes and a number of the body's messengers and signaling molecules are also formed by lipids.

Cell membranes, cholesterol, blood cells, and the brain are just a few places where they can be found in the human body.

Explanation:

Answer:

The correct answer is option a. "7.1".

Explanation:

One easy way to determine if a peptide sequence is acidic, basic or neutral is to check for the number of amino acid residues that are acidic, basic or neutral. In this case, most amino acid residues are neutral, which mean that under neutral conditions they have a pKa close to 7.0. Particularly, the content of 3 leucine, 2 alanine and 2 glycine residues determines that the peptide have a pI of around 7.1.

Explanation:

Answer:

Plants get their nitrogen indirectly from the air via microorganisms in the soil and in certain plant roots.

Answer:

Microorganisms and certain plant roots in the soil

Explanation:

"Plants get the nitrogen that they need from the soil, where it's already been fixed by bacteria and archaea. Bacteria and archaea in the soil and in the roots of some plants have the ability to convert molecular nitrogen from the air (N2) to ammonia (NH3)... Such organisms are called "diazotrophs". From here, various microorganisms convert ammonia to other nitrogen compounds that are easier for plants to use. In this way, plants get their nitrogen indirectly from the air via microorganisms in the soil and in certain plant roots."
