A euglena is a unicellular organism. Choose an everyday object, such as a car, to use as a model of this euglena. Explain how the parts of the object model how the euglena's cell parts help it stay alive.
Answers
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.
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.

What is effect of drug on ATP inhibition?Efrapeptins and aurovertins, two types of antibiotics, prevent ATP synthase from producing or breaking down ATP.
The rotor, the core cavity of the enzyme, and the particular -subunit catalytic site are where the efrapeptins bind to ATP synthase. This is because there won't be an ATP synthase-driven proton gradient.
The inability of the inner mitochondrial membrane to remain impermeable to protons or the cessation of electron transport will prevent oxidative phosphorylation from taking place.

John and Marissa purchase their first home for $120,000. They must put 15 percent down on the purchase price as a down payment. What will the amount of the down payment be?
Answers
Answer:
Downpayment: 15% of original price
Original price: $120,000
15% of 120,000 = [tex]\frac{15}{100}[/tex] × 120,000
= $18,000
Thus, the downpayment is $18,000.
John and Marissa purchase their first home for $120,000 than the Down payment is 15% of original price
Original price: $120,000
15% of 120,000 = × 12 = $18,000
Thus, the downpayment is $18,000.
What is down payment?Part A
The down payment of $48,000 is 20% of the purchase price
Part B
A $12,000 down payment will be 5% of the purchase price
A percentage is the expression of the product of the ratio of two numbers and 100
The amount the investors buy the studio apartment = $240,000
The amount the investors have as down payment = $48,000
Part A
The ratio of the down payment the investors have and the amount the investors buy the apartment = 45,000/240,00 = 0.2
Therefore, their down payment is 0.2×100 = 20% percentage of their purchase price
Their $48,000 down payment is 20% of their purchase price
Part B
The percentage of the purchase price a $12,000 down payment would be is given as follows;
12,000/240,000 × 100 = 5%
Therefore, a $12,000 down payment will be 5% of the purchase price.

Bob has brown hair and Sally has blonde hair. If brown hair is dominant and blonde hair is recessive, is it possible for Bob and Sally to have a blonde-haired child? Use the GENOTYPE of each parent to EXPLAIN your answer.
Answers
Answer:
Yes, it is possible.
Explanation:
Bob could either be h.o.m.ozygous (BB) for brown hair or h.e.terozygous (Bb) for brown hair. If Bob is h.e.t.erozygous for brown hair, this means he has a blonde hair allele. For a child to be blonde, the child needs one blonde allele from each parent and this is possible if Bob has a blonde hair allele. However, it is not possible if Bob is h.o.m.ozygous for brown hair.
In the image, there is a punnet square showing the possible genotypes of the children if Bob is h.e.t.erozygous for brown hair.

for an enzyme to be able to catalyze a reaction, the active site must —
Answers
Answer:
Active site of an enzyme must be attached to a substrate
Explanation:
Active site of an enzyme must be attached to a substrate
For an enzyme to be able to catalyse a reaction, the active site must bind with the specific substrate. This is referred as 'enzyme-substrate' complex.
Why do enzymes catalyse a reaction?Enzymes have the property of catalytic activity. All the enzymes are proteinaceous in nature. Enzymes specifically bind with the substrate and thus initiates a catalytic reaction. This is referred as enzyme-substrate specificity.
Enzymes associate with the substrate at a specific site by lowering the activation energy. This forms the active site where the reaction occurs. The substrate thus transforms into the product upon the action of enzyme.
Enzymes are unique as they speed up any chemical reaction. They help in achieving the equilibrium at a faster rate. Daily thousands of enzymatic reactions are carried out in the body.
Thus, enzymes are important in the biochemistry as they persuade chemical reactions.

In which biological event is chemical energy transformed into mechanical energy?
O muscular movement
O
photosynthesis
O bioluminescence
Answers
Muscular movement is the correct answer
The event in which the chemical energy transformed into mechanical energy is muscular movement. The correct option is A.
What is muscular movement?Muscles contract and then relax to move body parts. Muscles can pull bones, and yet they can't push them back into position.
As a result, they function in pairs of flexors and extensors. To flex a limb at a joint, the flexor contracts.
We discussed the skeletal system and the gestures that can take place at joints, such as flexion, extension, abduction, inversion, and so on.
These movements are produced by skeletal muscles pulling bones in different directions.
When ATP is hydrolyzed during cross-bridge cycling, chemical energy is converted to mechanical energy during muscle contraction.
As the muscle deforms or performs external work, this mechanical energy is distributed and stored in the tissue.
Thus, the correct option is A.
