A Euglena Is A Unicellular Organism. Choose An Everyday Object, Such As A Car, To Use As A Model Of This

Answers

Answer 1

Answer:

a car:

Flagellum  is a long thread-like structure that works as a navigator or a steering wheel in a car. The thin filament helps an euglena to move forward in any direction it desires.

Cell membrane is like the doors on a car. They regulate what goes in/out. The cell wall in a plant cell is like the frame on a car. The frame supports the car as the cell wall supports the plant.

The Nucleus is like the front seat of your car because the driver is in control of what the car does, goes, and what happens inside of the car.

Vacuoles is like the Trunk of your car because you store food, water and other wastes into your trunk, like were all the things go in the vacuoles.

The compression stroke in a car engine is like chloroplasts because it gas to fuel a car the same way chloroplasts convert solar energy in to chemical energy for a cell.

Mitochondrion is like the battery on a car. It gives the motor energy so it can run like the mitochondrion produces energy for the cell.

Eyespot is like a radio, because in some cars, radios pull power directly from the battery from the car battery, and this is why you will get the car radios on while the engine is off

Explanation:

The internal structures found in a typical photosynthetic Euglena are as follows:

Pellicle: A thin, flexible membrane that supports the plasma membrane and helps them to change shape

Plasma Membrane: The selectively permeable membrane that protects the inner content of the cell from the outside environment

Cytoplasm: A jelly-like substance distributed throughout the cell that contains all the cell organelles

Chloroplast: Contains the green pigment chlorophyll that helps them to produce food using sunlight by photosynthesis

Nucleus: A membrane-bound organelle that contains the genetic material, DNA. It also contains a distinct nucleolus that contains RNA and helps the cell to synthesize proteins

Mitochondria: The energy-producing organelle that forms ATP. All cellular activities such as movement and reproduction are performed using the mitochondrial energy source

Ribosomes: Consists of RNA and proteins, and are responsible for producing all cellular proteins

Golgi Apparatus: Manufactures, stores, and transports large molecules such as carbohydrates and proteins within the cell

Endoplasmic Reticulum: The extensive network of membranes that helps to package and transport proteins to different organelles. It is of two types: rough endoplasmic reticulum (RER) – containing ribosomes attached to it; and smooth endoplasmic reticulum (SER) – devoid of ribosomes

Lysosomes: Small membrane-bound organelles filled with hydrolytic enzymes that break down large molecules such as carbohydrates, fats, and proteins

Contractile Vacuole: It maintains the water and salt balance within the cell

Reservoir: The inward pocket present near the base of the flagella where contractile vacuole dispels excess water

Flagellum: A long whip-like structure attached externally to the cell body that helps in cell movement. An amoeba contains two flagella, a short one that does not protrude out of the cell, and a long one that helps in swimming

Eyespot: A region that is highly colored and contains red-colored carotenoid pigments that help in the detection of light. It is sometimes called a stigma

Photoreceptor: Also known as the paraflagellar body, it is the light-sensitive region located near the flagellum that helps to detect light. It also helps in their movement towards and away from light stimuli, a process known as phototaxis  

Paramylon: They are stored starch-like carbohydrate granules composed of glucose produced during photosynthesis. Paramylon enables the organism to survive in low-light conditions when photosynthesis is not possible by acting as the food reserve for the cell. When the paramylon is enclosed in a sheath of polysaccharide, it is called the paramylon sheath of pyrenoid.

Answer 2

The flagellum of euglena, can be compared to the wheels of a car, as they are responsible for the movement of both.

What is Euglena?

Euglena is a genus of single-celled flagellated algae that can occur either as free cells or in colony form.

What is flagellum?

Euglenophytes have the presence of flagella as their main characteristic. They have two flagella, one longer than the other. The smaller flagellum does not emerge from the cell. The larger one is mainly used for locomotion.

With this information we can conclude that euglena has flagella for locomotion just as cars have wheels for locomotion.

The brightness of light is related to intensity or the amount of light an object emits or reflects.

What is brightness?

Brightness depends on light wave amplitude, the height of light waves. Brightness is also somewhat influenced by wavelength.

When a source appears to be reflecting or radiating light, it is said to be bright. It's critical to comprehend the terminology and technology utilized in the lighting sector.

Lumens are a unit of measurement for light output from a bulb. A light's lumen count indicates its brightness; a lower lumen count indicates a dimmer light. Weight is like bananas, To milk are gallons, Lumens enable you to purchase the desired amount of light.

Therefore, The brightness of light is related to intensity or the amount of light an object emits or reflects.

The controversy surrounding dissociative identity disorder as a diagnosis is that accounts of dissociation based on current diagnostic scales are invalid because the design of the scales increases the possibility of false positives.

Stress may play a role in misdiagnosis because individuals who have experienced stress may be more likely diagnosed as having dissociative identity disorder.

Misdiagnosis is described as an incorrect conclusion about the cause of a disease or problem.

One possible hypothesis for the Protein Synthesis Gizmo could be: "If the availability of amino acids is increased, then the rate of protein synthesis will also increase."

This hypothesis suggests that the amount of protein synthesized by the cell is directly influenced by the availability of amino acids, which are the building blocks of proteins. Amino acids are monomers of protein.

By increasing the supply of amino acids, it is expected that the cell will have more resources to engage in protein synthesis. It causes an increase in the rate at which proteins are produced.

rita has two small containers one holding liquid and one holding a gas rita transfers the substances to two larger containers compare the behaviors in the atoms in the liquid and in the gas once they are moved to larger containers

Answers

Answer:The behavior of the both liquid and gas will be different in some aspect and same in the other, lets see how:

Explanation:

As we have studies that liquids donot have a specific shape but do have a specific volume. So when the liquid will be transferred from small to large container, it will adapt the shape of new container but its volume will stay same as it was in old container.

On the other hand, about gases, we know that they donot have specific shapes and the volume is also not definite and depends on the shape of container. Therefore, the gas atoms will freely move in the container and the volume will be changes in large container.

A model cell with damaged DNA was created to explain the importance of checkpoints in a cell cycle. The G2 checkpoint accidentally failed to work during experimentation. What do you think is the likely consequence of this failure?.

Answers

Answer: the consequenc of this failure is The cell continued to divide uncontrollably to create more damaged cells Which can lead to deadly diseases like cancer, breast cancer and many more

If the G2 checkpoint accidentally failed, then the cell will enter into division. The likely consequence of this failure is that the cell proliferates in an uncontrolled manner.

The cell cycle is controlled by checkpoints that regulate the progression through different phases of the cell cycle.

The G2 checkpoint acts to prevent the entry in mitosis of cells that have damages in its genetic material (DNA) in order to repair it.

When the cell undergoes failures in the G2 checkpoint control, the cell divides in an uncontrollable manner and thus generate groups of damaged cells (e.g., a tumor).
