En un tanque de agua se sumerge un diapasón que vibra con una frecuencia de 600Hz. Las ondas sonoras resultantes en el agua tienen una longitud de onda de 2,5m. ¿Cuál es la velocidad del sonido en el agua?
Answer:
1500 ms-1
Explanation:
La velocidad de una onda se obtiene de;
Velocidad de onda = frecuencia * longitud de onda
Cuándo;
Frecuencia = 600 Hz
Longitud de onda = 2,5 m
Luego se deduce que la velocidad del sonido en el agua = 600 Hz * 2,5 m = 1500 ms-1
Which option describes the question Dave should consider in the following scenario?
Dave's mare has just given birth to a healthy colt, but he is surprised that the colt was born tan when the mother is
black
What color are the colt's eyes?
What nutritional supplements were given?
What other maternal traits were inherited?
What color is the colt's father?
The color of the colt's coat is determined by the genes it inherited from its parents is “What color is the colt's father?”, option D is correct.
Coat color in horses is a complex trait that involves several genes. The most well-known coat colors are black, bay, and chestnut. However, there are many variations and combinations of these colors, such as the tan color observed in this colt.
The color of the eyes is not related to the coat color and is determined by a different set of genes. Nutritional supplements may play a role in the overall health and development of the colt, but they are not likely to affect its coat color. Maternal traits, such as temperament and size, are also inherited, but they are not related to the coat color either, option D is correct.

Explanation:
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.

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.
Quasars are very luminous, very distant active galaxies.

Explanation:
In a lever, 120 N load is attached at a distance of 20 cm from the fulcrum. If this effort is used to lift 50 kg weight then, the load distance is:!?
Answer:
The load distance is 4.9 cm
Explanation:
Given;
Effort applied to the lever, E = 120 N
Load overcame by the effort, L = 50 kg = 50 x 9.8 = 490 N
distance of the effort from the fulcrum, e = 20 cm
let the distance of the load from the fulcrum = d
The following simple set-up is used to illustrate this lever;
-----------------------------Δ-------------------------------
↓ 20cm d ↓
120 N 490 N
Lever operates on the principle of moment, so take moment about the pivot (fulcrum);
490(d) = 120(20)
d = (120 x 20) / (490)
d = 4.9 cm
Therefore, the load distance is 4.9 cm
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
3.
If a hawk eats 30% of the weasel population, weasels eat 30% of the mouse population, and
mice eat 20% of the wheat plants, calculate the total numbers of each organism that exist in
this ecosystem
a. Start by finding how many weasels there are to support the one hawk
i. # of weasels eaten 7.3 = total weasels
ii. total weasels x # of mice needed / .3 = total mice
iii. total mice x # of wheat plants needed / .2 = total wheat plants
Answer:
a. Approximately 1,003 weasels, 3,345 mice and 16,729 wheat plants per one hawk are in the ecosystem
Explanation:
The percentage of the weasel population eaten by a hawk = 30%
The percentage of the mouse population eaten by a weasel = 30%
The percentage of the wheat plants population eaten by a mice = 20%
a. One hawk needs 330 kJ of energy per day, which gives 330 kJ × 365 = 120,450 kJ per year
Let 'x' represent the number of weasels to support one hawk, we have;
0.3 × x = 120,450 kJ/year/(400 kJ) = 301.125
x = 301.125/0.3 = 1,003.75
The number of weasels required to support one hawk per year ≈ 1,003 weasels
The total weasels ≈ 1,003
ii) The number of mice needed, y = x/0.3 = 1,003.75/0.3 = 3,345.8[tex]\overline 3[/tex]
The total mice, y ≈ 3,345 mice
iii) The number of wheat flower needed, z = y/0.2
∴ The number of wheat flower needed, z = 3,345.8[tex]\overline 3[/tex]/0.2 ≈ 16,729.1[tex]\overline 6[/tex]
The total wheat plants ≈ 16,729.

option c
Explanation:
The genes that can give you red-green color blindness are passed down on the X chromosome. Since it's passed down on the X chromosome, red-green color blindness is more common in men. This is because: Males have only 1 X chromosome, from their mother.
Scenario 1
A male patient has been treated for tendonitis of the elbow. He calls the office to complain that for the past
two days he has experienced an increase of pain and feels he is worse than when he was first diagnosed. He has been applying heat like he was advised. He wants to know what to do.
The male patient would be required not to put a heating pad on his elbow as this makes it worse, but he needs to put an ice pack over it which keeps it relaxed and take naproxen.
What is Diagnosis?Diagnosis may be defined as the complete methodology or process of identifying a disease, condition, or injury with respect to its signs and symptoms. This process determines the actual cause of the pattern of disease or injury that an individual is suffering.
Tendinitis is generally an inflammation of the thick fibrous cords that typically attach muscle to bone. These cords are called tendons. When an individual is suffering from tendonitis of the elbow, he/she must be required to put or apply ice packs rather than heat packs over it. This makes them feel relaxed and cures it.
Therefore, the male patient would be required not to put a heating pad on his elbow as this makes it worse, but he needs to put an ice pack over it which keeps it relaxed, and take naproxen.

How is water traveling underground to lost Lake?
Answer: Water becomes the part of the aquifer.
Explanation:
Water from rain, snow fall, river, lakes, ponds, ocean, irrigation field, and from other sources become the part of the ground water or aquifer. The water seep into the soil or rocks and deposited as reservoir of water underground. The underground water when exposed to the surface can become the part of the lost lake or any other water body. Thus the source of lost lake can be determined this way by tracking the distance covered by the ground water.
