Answer:
Mutation is important as the first step of evolution because it creates a new DNA sequence for a particular gene, creating a new allele.
Explanation:
Explanation:
Gravitational potential energy = mgh, where m is the mass of the mountain climber, g is the gravitational force and h is the height from the base.
Since m and g are constants, the climber's potential energy will be the lowest when he's at the end of the climb, at the base of the mountain. (B)
Answer:
temporal reproductive isolation
Explanation:
The correct answer would be temporal reproductive isolation.
<u>Reproductive isolation</u> generally refers to series of biological mechanisms or processes that prevent members of different species from mating/fertilization or prevent the product of their mating to be invalid.
Some reproductive isolation processes prevent members of different species from mating or prevent fertilization as a result of mating. These processes are known as pre-zygotic reproductive isolation mechanisms.
Some other processes ensure that the product of fertilization (when it occurs) is invalid. These are known as post-zygotic isolation mechanisms.
<em>A good example of the pre-zygotic reproductive isolation process is </em><em>when closely related by different species bloom at different times</em><em>. This will prevent mating or cross-pollination to happen between the different species. This is known as temporal reproductive isolation.</em>
I'm not 100% sure but I would say watermelon. Watermelon is predominantly water like most melons.
Answer:
Si, esto es lo que se conoce como circulacion menor.
Explanation:
La sangre cumple un recorrido en el corazon a la cual se la llama circulacion mayor, una vez que se continua su camino hacia los pulmones ahi ya pasa a ser circulacion sanguinea menor.
Estas circulaciones estan sumamente coordinadas y tienen un orden ritmico, con un unico fin, que es oxigenar la sangre que se recolecta de todo el organismo.
Es asi como la sangre que viene con CO2 entra a los pulmones posterior a la eyeccion cardiaca y cumple con el proceso de homeostasis en el alveolo y se oxigena.
