Answer: Option D. "Anther"
Explanation:
The stamen is defined as the male reproductive part of flowers that produces pollen in a flower and collective form of stamens is called the androecium.
Their are two parts of stamen, Filament and Anther.
Filament is the stalk of a stamen which supports anther whereas anther are two-lobed responsible for producing pollen.
Hence, the correct option is D, Anther.
In all cases, except case 1 the forces are unbalanced, and therefore, the net force is different from 0.
<h3>How forces act?</h3>
In physics, forces are balanced if opposite forces have the same magnitude, for example:
- If two people are pulling a rope with a 5N force the forces are balanced and the rope will not move.
Based on this, from the diagrams presented only diagram 1 has balanced forces because this is the only case in which opposite forces have the same magnitude.
<h3>Let's calculate the net force in each case or the total sum of forces. </h3>
To do this, consider that forces pointing upwards and to the right are positive.
Case 1
- Net force: 10 N + 10 N - 10 N - 10 N = 0 N
Case 2
- Net force: 10N + 15 N - 10 N - 10 N = 5 N
- The direction of this object is to the right because the strongest force goes in that direction.
Case 3
- Net force: 17 N + 17 N - 10 N - 12 N = 12 N
- The direction of this object is to the right and upwards because these are the two strongest forces.
Case 4
- Net force: 17N + 10 N - 10N - 12 N = 5 N
- This object will move upwards because this is the strongest force.

Neurons, cardiac muscle, Red/white blood cells, skeletal muscle, smooth muscle, sperm cells, egg cells
Explanation:
Brodribb and Feild argue that more photosynthesis meant more carbon for growth. And that would have given the angiosperms the energy to push competitors like conifers out of the canopy around 150 million years ago, making angiosperms the most productive group of land plants in the world.
