Answer:

F2:

-75% plantas con flores púrpuras

- 25% plantas con flores blancas

Explanation:

La F1 de un cruzamiento entre líneas puras para un rasgo dominante monogénico (en este caso, color de la flor) es siempre igual al fenotipo para el carácter dominante (en este caso, plantas con flores púrpuras). En este ejemplo, el alelo dominante que codifica para el color púrpura enmascara la expresión del alelo recesivo (flores blancas) en plantas F1 heterocigotas. Por otra parte, el cruzamiento entre plantas F1 con genotipo heterocigoto producirá una F2 con una proporción fenotípica 3:1 (es decir, 3 plantas con fenotipo dominante por cada planta con fenotipo recesivo), lo cual es igual a un 75% de plantas con fenotipo dominante (tres plantas: una con genotipo homocigota dominante y 2 con genotipo heterocigoto) y un 25% de plantas con fenotipo recesivo (una planta con genotipo homocigota recesivo). Esto sucede porque los alelos dominante y recesivo responsables del color de la flor segregan independientemente durante la formación de los gametos en plantas F1 heterocigotas.

George Monbiot is spearheading the Rewilding Movement. The environmentalist and writer is prominent in the platform. He was featured in TED Talk and talked about a large scale conservation approach aiming to restore the lost habitats. Here is an excerpt of his speech where he discusses the lost megafuna:

"What megafauna, you say? Well, every continent had one, apart from Antarctica. When Trafalgar Square in London was excavated, the river gravels there were found to be stuffed with the bones of hippopotamus, rhinos, elephants, hyenas, lions. Yes, ladies and gentlemen, there were lions in Trafalgar Square long before Nelson's Column was built. All these species lived here in the last interglacial period, when temperatures were pretty similar to our own. It's not climate, largely, which has got rid of the world's megafaunas. It's pressure from the human population hunting and destroying their habitats which has done so."

Explain how animal like plant like are similar and different
Delvig [45]

Answer: The main way animal-like protists differ from plant-like protists is in the way they get energy. Animal-like protists are heterotrophs. ... Plant-like protists, on the other hand, are autotrophs. They can make their own energy from the sun or other sources just as plants can.

Why is a theory called a theory and not a fact?
Black_prince [1.1K]
Many theories can never be proven. 
Here are a few examples:

-- The moon orbits the Earth.
-- Gravity pulls all masses toward each other.
-- The Earth orbits the sun.
-- Everything is made of atoms and molecules.
-- Atoms are made of protons, neutrons, and electrons.
-- Electrons moving through a wire make electric current.
-- The center of the Earth is molten iron and nickel.
-- The source of the sun's energy is nuclear fusion in its core.
-- Almost all galaxies are moving away from us.
-- The universe is expanding.

None of these statements can be proven.  That's why they're not called
Facts or Laws. 

It also tells you that some pretty powerful stuff has been done with concepts
that can't be proven.  If you want to make an idea look foolish, that doesn't
happen when you say "it's only a theory".
