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.
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.
Black bears in the north hibernate mostly due to the scarcity of food during the winter months.
Prior to hibernation bears are foraging for food. They eat fruit, nuts, acorns, insects, and certain leaves and plants. They catch occasional small animals, but lack agility to catch most adult prey. In the months before hibernation black bears can gain up to forty pounds of fat per week.
9. What types of food molecules is the bear consuming (give at least two)?
Answer:
Food having high fat.
Explanation:
The bear eat food products having high fats in order to store it in the body. The food which have large amount of protein and fats are stored in the body and helps in gaining of weight up to forty pounds of fats per week. During hibernation period, bear used this fats for the release of energy used for its survival. Fats produce huge amount of energy when they are broken down so this fats helps in hibernation of bear.
Into what kingdom would each of the following be classified:a. Unicellular prokaryotes that live in dust. _______________________[Text Wrapping Break] b. Unicellular eukaryotes that line in pond water. _____________________[Text Wrapping Break] c. Multicellular eukaryotes that live all over the planet and consume food. ______________________ [Text Wrapping Break] d. 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.

Explanation:
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.

do you think that if someone has the trait for tasting PTC, they could still like broccoli or Brussels sprouts? Explain.
Answer:
The ability to taste PTC or the chemicals in Brussels sprouts is not the same for everyone. You do not have to worry about picking and eating poisonous plants, but because some vegetables like Brussels sprouts and broccoli have these bitter chemicals in them, many people do not like them

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
what does a root hair cell do
Answer:
Root hair cells (black arrow pointing at one of the root hair cells) are single tubular root cells. Their distinctive lateral elongation increases the surface of exchange between the plant's root system and the soil. The main function of root hairs is the uptake of water and nutrients from the rhizosphere.

What’s pushes the pathogens away from lungs?
Cilia
Explanation:
Pushes mucus away from the lungs along with any debris that may be trapped in the sticky mucus
Which statement is correct?
help plsss
The cells that make up lungs and the cells that make up kidneys have different genes, causing lungs and kidneys to look different.
All cells of an organism have the same genes, but different genes are activated within different cells.
When cells and tissues differentiate, they delete the genes they do not need.
All cells have the same genes, and all of a cell's genes are active at the same time.
