Answer:
3) Provides most of the cells energy
Explanation:
The main functions of the mitochondria is to provide energy to most of the cells. Known as the (Powerhouses of The Cell), mitochondria produce the energy necessary for the cell's survival and functioning. Through a series of chemical reactions, mitochondria break down glucose into an energy molecule known as adenosine triphosphate (ATP), which is used to fuel various other cellular processes. Present in nearly all types of human cell, mitochondria are vital to our survival. They generate the majority of our adenosine triphosphate (ATP), the energy currency of the cell. Mitochondria are also involved in other tasks, such as signaling between cells and cell death, otherwise known as apoptosis
Answer:
It was the sudden appearance (over a 10my period) of many different organisms, which occurred approx 540-548 mya. ... So it can be away from sources of oxygen, preventing microorganisms from decomposing the organism.
The correct answer for the question that is being presented above is this one: "Yes, because the observed changes in histone modifications are consistent with reduced transcription." The results shown in Figure 19.5 prove conclusively that histone modifications are causing reduced Hnf4a gene transcription because <span>the observed changes in histone modifications are consistent with reduced transcription.</span>
Answer:
Explanation:
El Parque Nacional de Yellowstone (Estados Unidos), considerado el parque nacional más antiguo del mundo, fue creado en 1872 durante la presidencia de Ulysses S. Grant. En sus inicios, la fauna del parque no recibió la misma protección que hoy en día: los lobos y los pumas fueron eliminados deliberadamente en 1926 y, al cabo de unos años, la población de ciervos aumentó tanto que los administradores del parque reconocieron que los herbívoros estaban alterando la vegetación, por lo que se realizaron matanzas selectivas para controlar la población de dichos animales. Las matanzas selectivas terminaron a finales de los años 60 y la población de ciervos volvió a aumentar, por lo que finalmente se optó por reintroducir el lobo: 14 lobos de la provincia de Alberta (Canadá) fueron liberados en 1995 y otros 17 lobos canadienses en 1996. "La reintroducción del lobo (Canis lupus) en el Parque Nacional de Yellowstone es el experimento ecológico más celebrado de la historia", así comienza un estudio publicado en Journal of Mammalogy por Mark Boyce, de la Universidad de Alberta.
The right answer is dihybrid crosses.
<span>A dihybrid crossing is a reproduction between two organisms that differ in two traits. Individuals of this type of cross are homozygous for a specific trait.
The traits are characteristics that are determined by DNA segments called genes.
Diploid organisms inherit two alleles for each gene.
An allele is an alternative version of an inherited gene (one of each parent) during sexual reproduction.</span>
