Arrange the events in the life cycle of mosses in the flowchart below. Start the life cycle with the mature sporophyte stage in
labwork [276]

Answer:

Life cycle of a moss

Explanation:

LIFE CYCLE OF A MOSS FROM MATURED SPOROPHYTE STAGE

An embryo further develops into a pear-shaped  sporangium, which is the *sporophyte  stage of the plant*. The sporangium  contains spore sacs, each of which is the spore mother cell that undergoes meiotic division  to form four spores,The spores are released and germination

takes  place giving  rise to a protonema, which develops into a new gametophyte plant. The gametophyte  generation or haploid phase of the moss is from the production  of haploid spores after meiosis  to the period just before fusion of the haploid antherizoid or haploid ovum. The sporophyte generation or diploid  phase is from the diploid  mother cells just before meiosis.

Examples of moss plants include Funaria hygrometrica, Polytrichum commune, Barbuda Indica.

What occurrence would contradict the big bang theory?
VARVARA [1.3K]
The big bang theory states that the universe began approximately 10-20 billion years ago in an expansion of the universe emanating from an extremely compact point. The occurrence of super massive black holes contradict the big bang theory. Super massive black holes are found at the center of galaxies and is what keeps them together. Models do not explain how these would have formed if the big bang occurred the way it was proposed.

In pea plants, round (R) is a dominant trait, and wrinkled (r) is a recessive trait. Which combination would result in wrinkled
Artyom0805 [142]
