Answer:
D) None of the above
Explanation:
Arthropods are characterized by the possession of an exoskeleton and a segmented body. This group includes insects, arachnids, myriapods (centipedes and millipeds), and crustaceans.
The Devonian period, belonging to the Paleozoic Era, occurred from around 415 million to 350 million years ago. During this era, arthropods such as centipedes, millipedes, and flightless insects were predominant and diversified throughout this period.
Therefore, as all of these arthropods were present in the Devonian period, the correct answer is <u>d) None of the above</u>.
Answer:
The correct answer would be - triploid plant.
Explanation:
Triploidy is a condition which can be defined as the 3 set of chromosome in an organism, the extra set of chromosome may be come from the maternal organism or the paternal derived. Maternal derived triploidy known as the digynic while in in the case of the paternal derived called diandric.
In this case the sperm goes under the meiosis so the each gamete will have one chromosome of each set (I I I) while the egg failed to undergo meiosis so the gamete carry complete set of chromosome ( II II II ) after fertilization the outcome will be Digynic triploidy (III III III).
Thus, the correct answer would be - triploid plant.
Answer:
All choices are correct
Explanation:
The most well known was a botanist who studies plants too realized that plats,living things are made of cells so most likely the answer would be all living things are made of cells
I hope this helps, I am only in the 7th grade and this was pretty easy to me
