Answer:

A gene mutations can be defined as the permanent alteration in the sequence of the DNA that makes the gene. Gene mutation may give rise to genetic variations or from the genetic recombination.

These variations are known to alter the gene activity and the function of the protein. These variations in the protein or gene activity give rise to different traits in an organism.

How old do birds have to be to reproduce ?
Katena32 [7]
Birds reproduce sexually by mating and then depositing shelled eggs, which they incubate, hatch and rear. Birds produce sperm and egg cells just as mammals do, but most male birds lack a copulatory organ. Instead, birds mate through a process known as a “cloacal kiss.”

¿cuando se realiza el mismo proyecto pero en diferente lugar quiere decir que se tendran los mismos resultados
harina [27]

Answer:

Debido a que ocurren las mismas reacciones.

Explicación:

Cuando se lleva a cabo el mismo proyecto pero en un lugar diferente significa que se obtendrán los mismos resultados porque el organismo reacciona igual en cada condición ambiental pero en algún momento se obtendrán resultados diferentes debido al gran impacto de las diferentes condiciones ambientales en el organismo o en el unidad experimental. El organismo tiene el mismo tipo de reacción en diferentes ubicaciones o lugares, por lo que podemos decir que se obtendrán los mismos resultados al realizar el mismo experimento en diferentes ubicaciones.

Which features do all new rocks formed near an oceanic ridge share? Check all that apply.
slega [8]

Answer:

Options (1), (2), (3) and (4)

Explanation:

Mid oceanic ridge is the region along the spreading of the sea floor occurs. Along this ridge, the magma come out to the surface, and lava forms<u> pillow shaped rocks such as pillow basalt</u>. Basalt is the dominant rock type in the oceanic crust.

There occurs<u> striped patterns that are oriented parallel mid oceanic ridge</u>, and this strips depicts the magnetic field of the earth, and it keeps on changing on each eruption of this magma beneath the ocean long this ridge.

The mid oceanic ridge suggests the <u>spreading of the sea floor</u> and the rocks present at this ridge are younger than the rocks that are away from the ridge.

This rocks are comprised of the <u>molten iron material</u> that are present in the mantle and suggest the magnetic field of the earth during the time of eruptions.

Hence, the correct answers are options (1), (2), (3) and (4).
