Answer:
You multiply 0.5 by 20 which will give you 10 your answer is 10
the speed of a wave with a wavelength of 0.5 m and a frequency of 20 Hz is 10
what is speed ?Speed can be referred as the ratio of distance to the time in which the distance was covered which is a scalar quantity as it has only direction and no magnitude.
The speed is represented as s=d/t, Where, s is the speed in m.s-1, d is the distance traveled in m, t is the time taken in s
There are four types of speed like Uniform speed, Variable speed, Average speed, Instantaneous speed
Uniform speed is where the object covers equal distance at equal interval of time, variable speed is defined as when the object covers a different distance at equal intervals of times.
Instantaneous speed is defined as an object is moving with variable speed, then the speed at any instant of time is known as instantaneous speed.

O oxigênio é importante um gás na quebra de ligações entre os átomos que formam a glicose para a produção de energia. Por que a presença de ferro no nosso organismo é importante para este processo?
Answer:
It transport oxygen from lungs to the cells.
Explanation:
The presence of iron in our body is very important for this process because iron is responsible for the transportation of oxygen. Hemoglobin is made up of iron that takes oxygen from the lungs to each and every cell. Iron is an essential element for the formation of blood in human body. About 70 percent of body's iron is found in the red blood cells of our blood called hemoglobin and in the muscle cells called myoglobin. So we can say that iron is very important for the release of energy in the process of respiration.
¿Qué sucede si una célula se encuentra en la fase G0 del ciclo celular? ¿qué células nunca salen de esta fase?
Answer:
las células en fase G0 no se dividen. Un ejemplo de células en fase G0 son las neuronas y las células del músculo de corazón
Explanation:
El ciclo celular es una serie de eventos asociados al crecimiento y división de una célula. El ciclo celular consta de una fase de crecimiento o 'interfase' (la cual a su vez se divide en 3 fases: la fase G1, S y G2) y la fase de división celular (la cual a su vez se divide en mitosis y citocinesis). Sin embargo, hay células que no entran en fase G1 y en lugar de ello se dirigen a un estadio celular conocido como fase G0. La fase G0 es una es un estadio en el cual se encuentran células maduras que no se dividen hasta recibir un estímulo/señal que dispare la entrada de la célula en fase G1, donde la célula sintetiza los ARN mensajeros y proteínas necesarios para las etapas celulares posteriores que conducen a la división celular. Las células en fase G0 no crecen, pero poseen un metabolismo activo. Ejemplos de células en fase G0 incluyen las neuronas, células musculares poli-nucleadas, hepatocitos, etc. (es decir, células maduras y post-mitóticas que son incapaces de reproducirse).

Use the scenario to answer the following question. A forest ecosystem is home to mountain lions, coyotes, bobcats and deer. The deer eat grass. The mountain tions, coyotes, and babcats eat deer. Hunters began killing large numbers of mountain lions, coyotes, and bobcats. About twenty years later, the deer population had largely increased. The teacher asked the students to explain why the population of deer had a large increase in population size. Which student's argument MOST accurately explains the increase in the deer population? A Student 4: The deer population increased because with fewer mountain lions, coyotes, and babcats there was less competition within the deer population. B. Student 1The number of deer increased because deer populations are always increasing, even when there are mountain lions, coyotes, and bobcats preying on them. Student 3: The number of deer increased because with fewer mountain lions, coyotes, and bobcats, the deer had more food available to eat. D Student 2: The number of deer increased because without mountain , coyotes, and bobcats, the deer longer and had more offspring that also lived longer,
Answer:
A. student 4
Explanation:
The population of deer increase because with fewer mountain lions, coyotes and bobcats there was less competition within the deer population
The correct statement is that; The number of deer increased because without mountain , coyotes, and bobcats, the deer lived longer and had more offspring that also lived longer."
What is food chain?The food chain describes the feeding relationships that exists in nature. Now this ecosystem has the food chain; grass ---> Deer ----> babcats ---> coyotes ----> mountain lions.
Now we are also told that the mountain lions eat the the bobcats and the hunters are killing the mountain lions, coyotes, and bobcats, the predators of the deer hence been removed hence the deer population multiplies.
Therefore, the correct statement is that; The number of deer increased because without mountain , coyotes, and bobcats, the deer lived longer and had more offspring that also lived longer."

Pollutants concentrated in the northern part of the Gulf of Mexico often create a dead zone. A dead zone is an area of an aquatic ecosystem that does not have enough oxygen to support sea life. Some of the chemicals that cause the Gulf dead zone come from as far away as Montana. Use this information and what you know of United States geography to select the statement that BEST explains how pollutants from Montana have an impact in the Gulf of Mexico.
Answer and Explanation:
Hello. You did not present the answer options, but we can say that Montana pollutants have an impact on the Gulf of Mexico, due to the Mississippi River. That's because Montana and the Mississippi River are in the same hydrographic basin, which causes Montana pollutants to reach the Mississippi River, which takes these pollutants to the Gulf of Mexico, as the Mississippi River flows into the Gulf of Mexico.
Therefore, we can say that Montana pollutants are easily taken to the Gulf of Mexico and this impacts marine life in an influential way.

We have concluded that the spiders have different traits for silk flexibility because the offspring inherited different combinations of gene versions from their parents.
The evidence supports this claim because . . .
The is concluded that spider silk flexibility varies because their offspring inherited different combinations of gene versions from their parents, demonstrating that spider silk quality is dependent on the gene present in it.
What is the significance of the spider's silk?The quality of the spider silk is genetic, and due to this, some of the spiders do produce high-quality silk while others produce average or poor-quality silk, but the silk has many applications in various fields, such as biomedical fields such as in tissue engineering, drug delivery, and wound healing, due to its biocompatible, non-toxic properties.

Easy points: Is this a good paragraph for my biology class??The question was why is it important for soil to contain nitrogen, phosphorus, magnesium, and potassium.
Soil is one of the main sources of nutrients needed by plants in order to grow. Nitrogen is used by plants for leaf growth and green color. Without nitrogen in the soil, the plant wouldn’t grow tall and produce enough food.Phosphorus is used by plants to help form new roots, make seeds, fruit and flowers.This is crucial because crops take up phosphorus only from the soil solution.Potassium helps plants form strong stems and fast growth. It also increases disease resistance.It triggers activation of enzymes and is essential for production of ATP. Magnesium is the central core of the chlorophyll molecule in the plant’s tissue. If Mg is deficient, the shortage of chlorophyll results in poor and stunted growth.
Answer:
It makes the roots absorb the nutrients easier
Explanation:
the roots of the plant are meant to absorb water and nutrients for the plants to manufacture food easly and to grow, the soil contain nutrients for the plants to absorb them.
Which of the following is the best representation of the limiting factors affecting the elk population in this ecosystem?
O Number of scavengers, number of wolves, number of scientists studying Yellowstone.
Number of scavengers, and harshness of winter
Number of wolves, and harshness of winter.
The elk have no limiting factors
Answer:
Number of wolves, and harshness of winter.
Explanation: I took the test
The combination of factors that is capable of limiting the population of elk in an ecosystem would be the number of wolves and the harshness of winter.
The limiting factors of a population are those factors that hinder the population of an organism from increasing unlimitedly. In other words, limiting factors hinder populations from reaching their biotic potentials.
Limiting factors can be density-dependent if they have correlations with the density of species or density-independent if they have no correlation with an organism's density.
Wolves generally prey on elks, so they limit the growth of elk's population in an ecosystem. A harsh winter will also limit the overall growth of the population of elk in an ecosystem.
Scavengers cannot be a limiting factor to elk's population because they only feed on carcasses.

it is to do with something called angular moment. Gravity is the central force in the Universe, because it is the only one which has a significant pull over large distances.
5:Orbits are the result of a perfect balance between the forward motion of a body in space, such as a planet or moon, and the pull of gravity on it from another body in space, such as a large planet or star. ... These forces of inertia and gravity have to be perfectly balanced for an orbit to happen.
6;Gravity is the force that keeps planets in orbit around the Sun.
