The correct answer is B. Sensitive period
Explanation:
In development, the sensitive period refers to a lapse of time in which organisms are more susceptible or receptive to stimuli and therefore during this time there can be great advances in development. Additionally, different from critical periods sensitive periods do not imply irreversible consequence if the stimuli are not presented. For example, in human beings from birth to the age of 6 years, children are more receptive to learn and acquire certain skills such as learning a new language if exposed to it and therefore this can be considered as a sensitive period. Considering this, it can be concluded the definition presented refers to the Sensitive period.
Which planetary model allows a scientist to predict the exact positions of the planets in the night sky over many years?
A) The planets' orbits are circles in a geocentric model
B) The planets' orbits are circles in a heliocentric model
C) The planets' orbits are ellipses in a geocentric model
D) The planets' orbits are ellipses in a heliocentric model
<u>Answer:</u>
The planets' orbits are circles in a geocentric model is the planetary model allows a scientist to predict the exact positions of the planets in the night sky over many years.
<u>Explanation:</u>
- Ptolemy suggested that the model that the planets moving around the sun in a circular path. As the statement clearly explains that sun the middle of the solar system.
- Due to the gravitational pull of the sun, all the planets rotate around the sun in a circular path.
- All these are because of the universal law of gravitation. In the solar system, each planet has its path and they will rotate along with their path.
Answer:
They are sterile.
Explanation:
A mule is the offspring of a male donkey (jack) and a female horse (mare). Thus the number of chromosome of the donkey and the horse are quite different. A combination of the horse chromosome which is (64) and a that of the donkey chromosome which is (62) gives rise to 63 chromosomes in a Mule.
This major difference in number,forms and morphology typically prevents the chromosomes from pairing properly and producing successful embryos, as a result of this aftermath effect, it renders majority of the mules to be sterile.
