Since dinosaurs weren’t around anymore to eat the mammals, they were able to thrive and evolve to where they are today
Answer:
True
Explanation:
Mitochondria is present in almost all the eukaryotes and it contains its own DNA as its genetic material which is double-stranded and circular. The gene located on mitochondrial DNA are inherited only by mothers to their offspring.
As the mitochondrial DNA is transported from the female ovum therefore only mother can transfer the mitochondrial DNA to their children however some theories say that even the paternal mitochondrial gene can be transferred to offspring under some specialized condition.
Therefore it is true that genes located on mitochondrial DNA are usually inherited by mothers in their offsprings.

Explanation:
- One of the main differences between adult and fetal circulation is <em>the direction and where the non-oxygenated and oxygenated blood circulates</em>. In adults arteries carry oxygenated blood away from the heart and veins carry non-oxygenated blood towards the heart; in fetuses, arteries carry non-oxygenated blood away from the heart and veins carry oxygenated blood back to the heart.
- Another difference is <em>where does the exchange of gases takes place</em>, in fetuses blood is oxygenated in the placenta, in adults in the lungs.
- The circulation between adults and fetuses differs in <em>where does the pressure increases</em>, in adults is on the left side of the heart, in fetuses on the right side.
- Finally,<em> another important difference between adults and fetuses is the presence of shunts</em>, in fetuses these shunts allow both sides of the heart to work parallelly letting mix blood from both ventricles. This shunt gets closed after birth, so adults do not have them.

Answer:
<u>Depending upon the mass of various bodies and the gap between them, such as planets, satellites, etc., there appears a pulling effect between these massive masses. This pulling effect is known as gravitational force. One can establish the relationship of the orbital period by equating the gravitational force with centripetal force and substituting the velocity relation with the period.</u>
