Some tools have various levels of graduations. For example, a ruler may have graduations for both millimeters and centimeters. When measuring the length of an earthworm, which graduations would allow for the most accurate measurement?
Answer:
I would say Millimeters
Explanation:
Millimeters are smaller than Centimeters and can measure the length of an earthworm most accurately.
Hope this helps.
Millimeters would allow for the most accurate measurement.
What is Measurement?Measurement is defined as the quantification of characteristics of an object or phenomenon which can be used to compare them with other objects or phenomena. It is a process of determining how large or small a physical quantity is compared to a basic reference quantity of the same type.
It helps us to compare unknown quantities with known quantities. This helps us make quantitative statements about how big, how long, how fast things are. Without measurements, the final product would be full of errors.
Example:- Speedometer is used to measure the speed of vehicles.
A ruler marked in millimeters is more unique than a ruler best marked in centimeters, a millimeter being a smaller unit than a centimeter.
Thus, Millimeters would allow for the most accurate measurement.

Set up 1: Add a spoon of yeast+cold water leave for 10 minutes and observe the foam formation Set up 2: Add a spoon of sugar and a spoon of yeast add room temperature water leave for 10 minutes and observe the foam formation Set up 3: Add a spoon of sugar and a spoon of yeast add ice cold water and close the mouth with a plastic paper leave for 10 minutes and observe the foam formation. Measure the height of the foam formed in all the three set up. Under your finding. Give reason for your observation
Answer:
The foam was found higher where the water temperatures were higher, then continued the height of the foam where the water was cold and lastly the ice water.
Explanation:
Yeasts undergo alcoholic fermentation, and perform a chemical reaction consisting of the following conditions:
That there is a substrate, that is, some reagent that the yeast can metabolize to give ethanol as a product, in this case it is sugar.
That there is a relatively anaerobic medium, that is why it is closed with film.
That the sea temperature approximately 30 degrees Celsius so that the fermentation is favored.
The bubbling that we see is nothing more than the chemical reaction that the yeast fungus produces when metabolizing the carbohydrate, which in this case is type A sugar, to give ethanol as a product. This chemical reaction releases gaseous components as fermentation occurs, that is, the more bubbling, the faster the reaction and the better the fermentation.
In the situation where the water was freezing and the foam or bubbling was lower regardless of whether it was closed by a plastic, because the extremely low temperature in the water slowed down the reaction rate of alcoholic fermentation.
What do these characteristics all have in common?
These genetic traits can all be easily observed

Growth media are used to grow microorganisms in a lab setting. Some media are liquids; others are more solid or gel-like. A growth medium provides nutrients, including water, various salts, a source of carbon (like glucose), and a source of nitrogen and amino acids (like yeast extract) so microorganisms can grow and reproduce. Ingredients in a growth medium can be modified to grow unique types of microorganisms. For example; _____is a general-purpose, non-selective growth media, _____is a non selective, enriched growth medium with red blood cells that have been lysed by heat, Columbia Nalidixic Acid (CNA) and _____are selective agar for Gram positive organisms and ______agar is a selective agar for Gram negative organisms, Mannitol salt agar MSA is a commonly used selective and differential growth medium that encourages the growth of bacteria that ferments mannitol, and _____is an example of a liquid that supports growth of a variety of organisms.
Answer:
Growth media are used to grow microorganisms in a lab setting. Some media are liquids; others are more solid or gel-like. A growth medium provides nutrients, including water, various salts, a source of carbon (like glucose), and a source of nitrogen and amino acids (like yeast extract) so microorganisms can grow and reproduce. Ingredients in a growth medium can be modified to grow unique types of microorganisms. For example; Nutrient agar is a general-purpose, non-selective growth media, Chocolate agar is a non selective, enriched growth medium with red blood cells that have been lysed by heat, Columbia Nalidixic Acid (CNA) and Mannitol Salt agar are selective agar for Gram positive organisms and MacConkey agar is a selective agar for Gram negative organisms, Mannitol salt agar MSA is a commonly used selective and differential growth medium that encourages the growth of bacteria that ferments mannitol, Nutrient broth is an example of a liquid that supports growth of a variety of organisms.
Explanation:
Growth media are classified based on their composition as:
1. General Purpose Media: These type of media support the growth of non-fastidious organisms, that do not require special nutrients for growth, and they also serve as a base for certain modified media. An example is the nutrient agar
2. enriched media: these media, like the name implies, is one that has been modified by the addition of special growth factors and nutrients called enrichment. An example is chocolate agar where lysed blood is added to nutrient base agar, when the blood cells are lysed slowly at 80°C, nicotinamide adenine dinucleotide (factor V or NAD) and hemin (factor X), are released into the medium, and these support growth of certain fastidious organisms like Haemophilus influenza bacteria.
3. Selective media: These kinds of media contain substances that support the growth of certain organisms while in turn preventing the growth of others due to the presence of certain inhibitory factors. Examples are: Mannitol Salt Agar, which supports growth of Gram-positive organisms and MacConkey agar, which supports the growth of Gram-positive organisms
4. Non Selective media: These type of media have no biases against the growth of certain organisms, that is, they do not contain certain inhibitory factors that impede the growth of certain organisms.
5. Differential media: These media contain chromogenic agents that change colour and helps to differentiate one organism from the other, making for ease of identification especially for organisms with similar properties.
Finally, a broth is a growth medium that fo not contain agar, hence, it is liquid and not solid.
Sickle cell anemia is a genetic disease caused by a recessive allele. Sickle cell anemia affects the hemoglobin in red blood cells, making them the shape of crescents instead of disks. The disease can cause pain and damage blood vessels. A genetic counselor meets with a man and a woman that both are carriers of sickle cell anemia. Carriers have one copy of the sickle cell allele and one copy of the allele for making normal hemoglobin. What is the probability that the couple would have a child that was also a carrier for sickle cell anemia
Answer:
1/2
Explanation:
A genetic counselor meets with a man and a woman that both are carriers of sickle cell anemia.
The sickle cell anaemia genotype is ss where for producing normal haemoglobin, we have SS or Ss (Carrier).
When both man and woman are carriers, we have
S. s
S. SS. Ss
s. Ss. ss
Thus, the probability that the couple would have a child that was also a carrier for sickle cell anemia is 2/4= 1/2.

2. A mirror works by __________the light that hits
Answer:
1.A _shadow_ is formed when an _ transparent _ object blocks the path of light
2. A mirror works by _reflecting_the light that hits
Explanation:
1. A shadow is made when an object blocks light. The object must be opaque or translucent to make a shadow. A transparent object will not make any shadow, as light will pass straight through it.
2.When photons — rays of light — coming from an object (your smiling face, for example) strike the smooth surface of a mirror, they bounce back at the same angle. Your eyes see these reflected photons as a mirror image.

Hypothesize about tumor growth. Scientists have shown that tumor growth is an example of positive feedback loops. Why is tumor growth an example of positive feedback? In your answer elaborate using the following terms stimulus, receptor, control center, effector, response.
Answer:
Tumor growth is a process associated with the expression of oncogenic genes
Explanation:
The tumor cells often share oncogenic receptors that are expressed during oncogenesis. For example, it has been shown that the epidermal growth factor receptor is often mutated in brain cancer cells, thereby encoding an oncogenic that is overactive. These receptors are responsive to stimulus of nearby cells and thus act as effectors that amplify tumorigenic signals. In consequence, during tumor progression, tumorigenic effector cells have an uncontrolled proliferation and antiapoptotic signals are predominant. The nucleus in the cell functions as a control center where tumor suppressor genes are transcribed to fight against such oncogenic cells.
