Answer:
Al introducir una piedra en agua, está se va al fondo del vaso, por que es más pesada que el agua
Al introducir un bolígrafo, este flota, por que es más liviano que el agua
Si se introduce en agua un tajalapiz se evidenciará un proceso de corrosión del metal
Debido a la reacción con el agua, sin embargo el efecto será más evidente si se agrega sal a la mezcla
Potential gravitational energy is computed with the formula:
Where:
PEgrav = Potential gravitation energy (J)
m = mass (kg)
h = height (m)
g = acceleration due to gravity (9.8m/s^2)
Take note that acceleration due to gravity is a constant.
All you need to do is put in what you know and solve for what you don't know. So your given is the following:
PEgrav = 3,528J
m = 24 kg
g = 9.8 m/s^2
Put that into your formula:
The height of the cliff is 15m.
Answer:
Explanation:
As you probably already know, all of the cells in your body started from a single cell. That single cell then divided many, many times to turn into the 50 trillion or so cells that make up you. Almost all of the cells in your body share the same DNA as was found in that first cell
The components that make up the genetic code are common to all organisms! Same NUCLEOTIDES, same BACKBONE same BASE-PAIRS, same HYDROGEN BONDS! The instructions for making proteins (and traits) are in the sequence of nucleotides! These are the GENES that hold our similarities or differences
Answer:
This question lacks options, the options are:
A) symbiosis
B) ecosystem
C) community
D) population
E) biosphere
The answer is D) Population
Explanation:
Living organisms in an ecosystem are usually found in numbers living together in a given area. This is termed POPULATION in ecology. A population refers to the group of living organisms that belongs to the same species living together in the same habitat and have the ability to interbreed i.e. mate and reproduce with one another.
This is the case in this question where many sandhill cranes (large flying birds) were observed in a particular area, which represented their habitat. Asides the group of sandhill cranes living together, they were also observed to be interbreeding. This was evident in the observation of two sandhill cranes hopping up and down around their bright orange baby. This shows that members of the population are capable of mating and reproducing fertile offsprings.
This observation completes what a POPULATION is all about, hence, a population was observed.
The correct answer is <u /><em>a</em><em>daption</em>. The particular environment in which a particular environment is exposed to gives it the characteristic or the ability to adapt. This is how a particular ecosystem works. It is the relationship of organisms within their environment that evolves through time in order for it to survive and propagate into more adapted kinds of species.
