Answer:
Demostrar que los seres vivos surgen de los seres vivos es la principal razón para realizar experimentos.
Explicación:
El experimento de Pasteur en "Frascos cuello de cisne" ayudó a refutar la teoría de la generación espontánea porque Pasteur usó caldo de carne hervido en matraces cuello de cisne para mostrar que los microbios en el aire son responsables de causar la contaminación de los alimentos. Al mostrar que las criaturas vivientes surgen de la materia viva en su experimento, la teoría de la generación espontánea resulta inválida.
1 possible future is The Big Crunch. This theory assumes that the average density of the universe will be enough to stop its expansion and begin contracting.
2. Some theorists state that the expansion of the universe will go on forever, and if that happens, the universe will cool as it expands, and then it will become too cool to sustain life.
3. The Big Rip. The universe may keep expanding, as I mentioned before. But as it expands, the gravity may not be able to hold all the planets together, as it is now. Galaxies would tear apart first, followed by smaller black holes, planets and stars. Eventually, space would start expanding faster than the speed of light, and atoms would start breaking down into super small particles and everything would fall into nothing.

Answer:
A punnet square can be described as a diagram which is made to check the outcomes of a cross.
To check the probability of the offsprings of a cross between homozygous dominant thumb shape parent with a homozygous recessive thumb shape parent, let's draw a punnet square:
t t
T Tt Tt
T Tt Tt
The results of the punnet square depict that:
Genotype: All of the offsprings will be heterozygous for the thumb shape trait. Tt will be the genotype.
Phenotype: All of the offsprings will show the thumb shape like the thumb shape of the dominant parent.
(4) organisms in a changing environment must adapt to acquire necessary traits and survive
