Answer:
Megaspore—2n.
Explanation:
Angiosperms are the fruit bearing plants and reproduce by the process of sexual reproduction. The chromosome number are specific at each stage of the cell cycle of the angiosperms.
Microspores , egg are haploid. Zygote is diploid in nature. Megaspores get germinate into the female gametophytes and these are haploid in nature. Megaspores are also haploid in angiosperms.
Thus, the correct answer is option (b).
There are many biotic elements in a rainforest biome. But the most obvious one is trees, because biotic means living and trees are living.
Answer:
Eukaryotic and Prokaryotic cells are fundamentally different.
Explanation:
A prokaryotic cell is basically an entire organism that works within a single cell. Its genetic material is not in a nucleus.
A eukaryotic cell is part of an organism. This cell has its genetic material in the nucleus. In addition, it possesses organelles.
All cells are not the same because some, like the prokaryotic ones, make up an entire living organism. Others, like the eukaryotic cells, are part of much more complex living forms. Furthermore, each cell type within each category has unique functions.
An efficiency apartment can be compared to a prokariote. Prokariotes have everything they need in one cell. A mansion is more similar to a eukaryote. Every room of the mansion is important for the fully equipped mansion.
Answer: <u>Option 4; Oxygen gains electrons and hydrogen to form water.
</u>
Respiration is a process where glucose is used and energy is released stored in this molecule. Oxygen is used during respiration as well and it gains the electrons and hydrogen to form water. And, gain of electrons is an oxidation reaction. So answer is option 4.
Since, oxygen is consumed during respiration, option 1 is incorrect.
Loss of electrons is reduction, so option 2 is also incorrect.
Glucose is used in respiration, thus option 3 is incorrect.
