Cell, and gas are for sure made up of atoms so it’s either heat or a solid
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).
Answer:
D) Cartilaginous synchondrosis
Explanation:
Cartilaginous synchondrosis is a joint in which the bones are joined to the hyaline cartilage or the hyaline cartilage joins the bones.
The synchondrosis is of two types- the temporary and permanent synchondrosis in which the temporary synchondrosis represents the growth plate or epiphyseal plate of the hyaline cartilage which connects the shaft of the bones to the end of the bone.
The thickness of the epiphyseal plate in the children does not change as the bone lengthens.
Thus, D) Cartilaginous synchondrosis is the correct answer.
