This type of joint allows for a wide range of rotation and movement. The shoulder and hip are ball and socket joints.
Answer:
Esta afirmación es correcta ya que la ley de conservación de la energía es también aplicable a sistemas vivos
Explanation:
La ley de la conservación de la energía (la cual es la primera ley de la termodinámica) indica que la energía no se puede crear ni se puede destruir, solamente se transforma, de un tipo a otro. La ley de la conservación de la energía es de vital importancia para entender la existencia del mundo natural. En ecología, la energía fluye de un nivel trófico a otro en forma de biomasa, es decir, dentro de la cadena alimentaria. Esta energía no se puede crear ni destruir sino que es almacenada en los organismos, los cuales representan sistemas abiertos que intercambian materia y energía con el medio. Una vez dentro del organismo, una parte de esta energía es transformada (en plantas, por ejemplo, la energía es convertida en enlaces químicos durante la síntesis de carbohidratos), mientras que otra parte de la energía se elimina al exterior (por ejemplo, se disipa en forma de calor), pero la energía no se crea ni se destruye.
Answer:
Because of homologous recombination
Explanation:
- When genes are establish on different DNAs or far apart on the same chromosome, they are classified self-sufficiently and are said to be unlinked.
- When genes are very close together on the same chromosome, they are said to be linked. That means that alleles, or genetic versions, that are already together on a chromosome will be inherited as a unit more often than not.
- We can see if two genes are linked, and how closely, by using data from genetic crosses to calculate the frequency of recombination.
- Using the technique of discovery recombination happenings for numerous gene pairs, we can make link maps that show the order and relative distances of the genes on the chromosome.
- When the genes are on the same chromosome but far apart, they are classified independently due to crossing (homologous recombination). This is a procedure that happens at the start of meiosis, in which homologous DNAs randomly exchange matching fragments. Crossing be able to connection new alleles in combination on the same chromosome, causing them to enter the same gamete. When the genes are far apart, the crossing occurs with sufficient frequency for all types of gametes to occur with 25% percentage frequency.
- When the genes are very close together on the same chromosome, the crossing still occurs, but the result (in terms of the types of gametes produced) is different. Instead of being classified independently, genes tend to "stay together" during meiosis. That is, alleles of genes that are already together on a chromosome will tend to pass as a unit to gametes. In this case, the genes are linked
