Explanation:
Applying Concepts Your friend is playing a song on a piano. Whenever your friend hits a certain key, the lamp on top of the piano rattles. Explain why the lamp rattles.
Answer:
The lamp rattles because close resonant frequency.
Explanation:
The phenomenon of increased amplitude is known as resonance when the frequency of a periodically applied force is equal to or close to the natural frequency of the system it affects. When a resonant frequency oscillating force is applied to a dynamic system, the system oscillates with greater amplitude than when the same force is applied at non-resonant frequencies.
Resonant frequencies or resonance frequencies of the system are frequencies when the response amplitude is at a relative maximum. Due to the storage of vibrational energy, small periodic stresses at a resonance frequency of the system can cause significant amplitude oscillations in the system.
Thereforee, the lamp rattles because close resonant frequency.

"Draw a pedigree for hitchhiker’s thumb. Your pedigree should cover at least two generations and include both dominant and recessive forms of the trait. Label the pedigree with genotypes, using the letter H to represent the dominant allele for the trait and the letter h to represent the recessive allele."
I'm confused on the part about having two generations. How do I set up the pedigree?
Answer and Explanation:
First, you need to know how to interpret a pedigree representation.
Family members→ Individuals are represented with geometrical figures.
→ Males are squares
→ Females are circles
Trait/Phenotype→ Healthy/normal/not affected individuals are represented with empty figures
→ Affected/mutated individuals are represented with solid black figures
Generations→ Each file is represented with a roman number, indicating the Generation.
Now, what we need to do is to draw a pedigree for a hitchhiker’s thumb. We know that this is an autosomal dominant trait, which we will represent with an H. No hitchhiker's thumb is the recessive trait, and it will be represented with an h.
Our pedigree should cover at least two generations and include both dominant and recessive forms of the trait.
We can cross two heterozygous individuals, Hh, who are the first generation in our pedigree. This cross will result in a woman and a man with No hitchhiker's thumb, another man with a hitchhiker's thumb, HH, and another woman with a hitchhiker's thumb, Hh. These individuals will represent the second generation in the pedigree. Finally, we can cross the man with No hitchhiker's thumb, hh, with a woman who does not have a hitchhiker's thumb either, hh. And the woman with a hitchhiker's thumb, Hh, with a man with a hitchhiker's thumb, HH. The result of these crosses will be the third generation.The representation would be like following,
I → First-generation: First cross
Man Hh (1) Woman Hh (2)II → Second-Generation: F1 and second crosses
Man hh (3) x Woman hh (4)Woman hh (5)Man HH (6)Woman Hh (7) x Man HH (8)III → Third-Generation:
A boy (9) and a girl (10) hhA girl (11) HHYou will find this pedigree in the attached files. In this example, we included three generations. The first one belongs to the grandparents, the second one to parents, aunts/uncles, and the third one to grandchildren.
If you draw another pedigree, remember to include
the figures representing males and females, color and H/h representing the phenotype, Roman numbers representing the generations, and optional, numbers naming each member.

Un instructor desea preparar un experimento sobre movimiento armónico simple. Sólo dispone de una masa de 2 kg pero tiene una colección de resortes. ¿Qué constante elástica, en N/m, debe elegir para tener un período de 2 s?
Answer:
Constante de resorte, k = 19.745 N/m
Explanation:
Dados los siguientes datos;
Masa, m = 2 kg
Periodo, T = 2 segundos
Para encontrar la constante del resorte, k;
[tex] Period, \; T = 2 \pi \sqrt {\frac {m}{k}} [/tex]
Dónde;
T es el período. m es la masa del objeto. k es la constante del resorte.Haciendo k el tema de la fórmula, tenemos;
[tex] k = \frac {(2 \pi )^{2}m}{T^{2}} [/tex]
Sustituyendo en la fórmula, tenemos;
[tex] k = \frac {(2 * 3.142)^{2} * 2}{2^{2}} [/tex]
[tex] k = \frac {6.284^{2} * 2}{4} [/tex]
[tex] k = \frac {39.49 * 2}{4} [/tex]
[tex] k = \frac {78.98}{4} [/tex]
Constante de resorte, k = 19.745 N/m

Unicellular prokaryotes that live in volcanic ash. __________________________[Text Wrapping Break] e. Multicellular eukaryotes that have cell walls and are heterotrophic. _______________________[Text Wrapping Break] f. Multicellular eukaryotes that have cell walls and are autotrophic. ________________________
Answer:
A. Unicellular prokaryotes that live in dust. Monera.
B. Unicellular eukaryotes that line in pond water. Protist.
C. Multicellular eukaryotes that live all over the planet and consume food. Animals.
D. Unicellular prokaryotes that live in volcanic ash. Monera.
E. Multicellular eukaryotes that have cell walls and are heterotrophic. Fungi.
F. Multicellular eukaryotes that have cell walls and are autotrophic. Plants.
Explanation:
The 5 kingdoms are a way of classifying all living organisms on our planet, as each species inside a kingdom shares similarities with the other species in it.
Monera kingdom includes all of the prokaryotic organisms that exist, which includes bacteria and archaea. These beings are characterized by lacking a nucleus and membrane-bound organelles and having one single circular chromosome that is found in the center of the cell. They are unicellular. Example: escherichia coli.
Protists are the most primitive eukaryotes that exist, most of them are unicellular and microscopic, but possess a nucleus and specialized organelles like the rest of the eukaryotes have. Example: yeasts.
Fungi and Plants are quite similar, they are multicellular eukaryotes that have cell walls. Their main difference relies on the way they obtain nutrients: fungi are heterotrophs, they feed off living things; plants, however, are autotrophs and realize photosynthesis (they do not need to feed). Fungi and Plants also reproduce differently: fungi reproduce through spores; plants can reproduce sexually or asexually. Fungi example: amanita; plant example: cactus.
Animals are multicellular eukaryotic organisms that reproduce sexually and are heterotrophs (some feed off plants, some feed off other animals). They are characterized by their ability to move. Example: horse.

Scientific Definition of Mass:
Mass is the quantity of inertia (resistance to acceleration) possessed by an object or the proportion between force and acceleration referred to in Newton's Second Law of Motion (force equals mass times acceleration). In other words, the more mass an object has, the more force it takes to get it moving.
Why is it highly unlikely the adaptations seen in the killifish could occur in other species of
concern?
Answer/Explanation:
Killifish are unique in that their species contains a lot more genetic diversity than most animals. The genetic mutations that allowed some to adapt were already present in these populations. Species that are less genetically diverse may not have the right molecular tools to adapt.

Match each of the following terms with its description. 1. Arteries a) Tiny, thin-walled blood vessels that connect the smaller arteries to venules 3. Veins 4. Venules 5. Arterioles 2. Capillaries b) Thin-walled blood vessels that are less elastic than arteries c) Thick-walled, muscular, flexible tubes that carry oxygenated blood away from the heart to the arterioles d) Small arteries that deliver blood to capillaries e) Small vessels that connect the capillaries to the veins
Answer:
Arterioles - D
Arteries - C
Veins - B
Capillaries - A
Venules - E
Explanation:
This question is describing the blood vessels that make up the circulatory system. The blood vessels with their accurate description are as follows:
- ARTERIES: Arteries are the most elastic and thick-walled blood vessels that functions to carry blood away from the heart using great pressure. Arteries are muscular, flexible tubes that carry oxygenated blood away from the heart to the arterioles.
- VEINS: Veins are blood vessels that carry deoxygenated blood back to the heart. Veins have a thin wall and are less elastic in comparison with arteries.
- CAPILLARIES: Capillaries are smallest blood vessels designated to connect the smaller arteries or arterioles to venules. They are also thin-walled.
- ARTERIOLES: Arterioles are small arteries or branches of an artery that connects the arteries to capillaries. Arterioles deliver blood to capillaries.
- VENULES: Venules are tiny veins or branches of a vein that connects the veins to the capillaries. Venules deliver blood from capillaries to veins.
