if I subtract 20 from my number, then square the result, I get the same answer as if I square my number, then subtract 20 from the result
What is my number and how do you work it out?
The value of the unknown number is 10.5.
Let the unknown number = x
When 20 is subtracted from the number and the result is squared which is equal to the square of the unknown number minus 20:
(x - 20)² = x² - 20
expand the equation;
x² - 40x + 400 = x² - 20
collect similar terms together;
x² - x² - 40x = -20 - 400
-40x = -420
[tex]x = \frac{420}{40}\\\\ x = 10.5[/tex]

A elephant cell has 20 chromosomes. how many chromosomes will the cell have just before mitosis begins in the elephant cell?
The elephant cell will have 20 chromosomes.
Cells undergo interphase before getting to the mitotic phase. At the S phase of the interphase, the amount of DNA in the cell is double by replication. However, the number of chromosomes remains intact.
Thus, the cell gets to the mitotic phase with the same number of chromosomes that is usually present in normal vegetative cells of the animal.

a scientist finds an organism that has a single cell without a nucleus this organism was found in pond water in which kingdom does it belong to? explain what is the answer if you find the answer i will give you 100,000 dollars
Answer:
Protista
Explanation:
In biology, there are said to be six different kingdoms that an organism can be classified under. They include Animalia, Plantae, Fungi, Protista, Archaea/Archaebacteria, and Bacteria/Eubacteria.
With this in mind, you say that a unicellular (single-celled) organism without a nucleus was found in pond water. This would point to the Protista kingdom, which are also known as protists. These organisms are single-celled beings with no big nucleus that are typically found in environments like ponds.

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.
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.

the presence of a lophophore in a newly discovered species would suggest that the species ________.
Answer: the answer is has an exoskeleton
The lophophore is the feeding organelle in aquatic organisms. Its presence in a species suggests that the species is a suspension feeder. Thus, option D is correct.
What are lophophores?
Lophophores are the feeding organelles present in the marine invertebrates like Brachiopoda, Hyolitha, etc., of the Lophophorata group. They are used for respiration, brooding, and collecting food.
Suspension feeders use these lophophores to collect and feed on the suspended organic matter and particles in the water. Lophophorates are a major example of suspension feeders.
Therefore, the presence of the lophophores suggests the species to be a suspension feeder.

2) Why is the mixture of milk and bacteria incubated at 45 °C?
3) what causes the milk to thicken?
4) why does fermentation eventually stop?
5) Explain how making yogurt is a way of preserving the nutrients from milk.
It should be noted that milk is pasteurized at the start of the process in order to kill bacteria.
The mixture of milk and bacteria is incubated at 45 °C to kill the bacteria.The drop in pH causes milk to thicken. Fermentation is stopped when the alcohol concentration rises to a point where it kills the yeast cells.Lastly, making yogurt is a way of preserving the nutrients from milk as the bacteria ferment the milk thereby turning the lactose sugars to lactic acids.
