For the leaves to be presearved as fossil, they have to undergo a natural process of carbonization. This involves a slow chemical reaction with water over time that allows oxygen, nitrogen, and hydrogen to escape the leaves’ structure as gases leaving behind a carbon skeleton/film.
Answer:
What is the function of DNA and RNA
Answer:
c. number and variety of organisms vs. changing environment
Explanation:
In an ecosystem populations are in dynamic equilibrium with each other, for when a population decreases the population of its predators also decreases, because the various populations are dependent on each other for survival. What we can understand from this is that the diminishing population of a species has caused a change in the environment, making that environment unsuitable for the predator population.
In other words, dynamic equilibrium occurs when the size of a population of a species varies with changes in the environment in which they live. For this reason we can state that the number and variety of organisms vs. changing environment best indicates the dynamic balance of an ecosystem.
Answer:
Constante de resorte, k = 19.745 N/m
Explanation:
<u>Dados los siguientes datos;</u>
Masa, m = 2 kg
Periodo, T = 2 segundos
Para encontrar la constante del resorte, k;
Dónde;
- T es el período.
- m es la masa del objeto.
- k es la constante del resorte.
Haciendo k el tema de la fórmula, tenemos;
Sustituyendo en la fórmula, tenemos;
<em>Constante de resorte, k = 19.745 N/m</em>
Because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis<span> also produces genetic variation by way of the process of recombination.</span>
