Answer:
These are needed to mimic the blood vessels which these organs will use for the supply or drainage of fluids e.g blood.
In addition the empty tunnels serve as the routes for nutrients and oxygen supply for the organ.
In summary the tunnels provided a vascular structure to support the organ
Explanation:
Answer: C. It is the part of the stamen that contains the pollen
Explanation:
Anthers are the pollen containing units in a flower that can be found in the stamens of such flowers. It should be noted that typically, anthers consist of two parts which are referred to as the thecae and each one of the theca is made up of two microsporangia.
Therefore, from the explanation above, we can infer that the another is the part of the stamen that contains the pollen.
<u>Answer</u>: Infundibulum, ampulla, isthmus, uterus.
<u>Explanation</u>:
- The ovary produces the egg and, it releases one unfertilized egg every month.
- The egg then travels through the fallopian tube to the uterus.
- The fallopian tube consists of three parts:
1. <em>Infundibulum</em>- it is the most distal portion of the fallopian tube which receives the egg coming out of the ovary.
2. <em>Ampulla</em>- This is the next portion of the fallopian tube which is ciliated and is the site of fertilisation of the egg.
3. <em>Isthmus</em>- it is also a ciliated region which controls the transport of both sperm and the embryo.
- Finally, after passing through the isthmus the fertilized egg reaches the uterus where implantation takes place.
- <em>So the journey of the egg from the ovary to uterus follows the pathway, ovary---> infundibulum--->ampulla--->isthmus--->uterus.</em>

Given what we know, we can confirm that a semi-truck would have the highest gravitational attraction of the objects mentioned, while for the spaceship, its mass would <u>not change</u> during its trip.
<h3>Why would the truck have the highest gravitational attraction?</h3>
This has to do with how we calculate gravitational attraction. To summarize it greatly, this value is directly proportional to the mass of the object in question. The <u>more </u><u>massive </u>the object, the <u>more </u><u>gravity</u> it will produce. Therefore, since the semi-truck is the largest, it will have the greatest gravitational attraction.
<h3>Why does only the mass of the spaceship remain constant?</h3>
This has to do with the relationship between each value and the situation described. The acceleration and velocity will change as the ship loses fuel and is affected by the gravity of the earth and moon. The weight of the ship is also affected by gravity, whilst the mass is a physical property that <u>does not depend </u>on any of these and therefore <u>does not change</u>.
Therefore, we can confirm that a semi-truck would have the highest gravitational attraction of the objects mentioned, while for the spaceship, its mass would not change during its trip.
