Answer:
D. Division of body cells results in a greater variety of traits
Explanation:
Since sexual reproduction occurs between two organisms their traits are combined to form a new individual who has similarities and differences to both parents.
Answer: see explanation
Explanation:
(1). Substainibility actually means finite, renewable etc.
Sustainable resources are natural resources that are renewable and can be harnessed for important things for mankind without short of supply
(2). Water is too cheap, compared to its real value, and is rarely taken into consideration when decisions are made regarding resources. In general, decisions that determine how most of water is utilized are taken by a limited number of people.
(c). Reducing the development of thermal power stations: power station produces 80% of our electricity and consume a lot of water. We can do this by rewarding farmers that uses irrigation farming efficiently.
Answer:
The Miller and Urey experiment is a well-known classic experiment in which hypothetical conditions of the early Earth's evolution were simulated to test the possibility of chemical evolution. In fact, this was an experimental test of the hypothesis previously expressed by Alexander Oparin and John Haldane that the conditions that existed on primitive Earth promoted chemical reactions that could lead to the synthesis of organic molecules from inorganic ones. It was held in 1953 by Stanley Miller and Harold Urey. The apparatus designed for the experiment included a mixture of gases corresponding to the notion of the composition of the atmosphere of the early Earth in the 1950s, and electric discharges passing through it (simulating lightning strikes on the ground). The Miller and Urey experiment is considered one of the most important experiments in the study of the origin of life on Earth.
Explanation:
La siguiente entrada tiene como objetivo realizar una breve explicación sobre las moléculas biológicas lipídos y carbohidratos, las cuales son muy diversas ya que están formadas por carbono, lo cual hace que puedan formar muchos tipos de enlaces. Esta capacidad permite que las moléculas orgánicas adopten muchas formas complejas, como son las cadenas, las ramificaciones y los anillos.
Las moléculas biológicas son grandes polímeros que sintetizas para poder enlazarse con otras subunidades mucho mas pequeñas conocidos como monómeros. Las cadenas de subunidades estan unidas por enlaces covalentes los cuales se forman por deshidratación, estas cadenas pueden romperse por hidrólisis. La moléculas biologicas más importantes son los carbohidratos, lípidos, proteínas y ácidos nucleicos.
