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.
Answer:
RNA contains an additional oxygen atom on the ribose sugar. (Ans. C)
Explanation:
RNA contains a sugar which is known as ribose, and which contains an extra group of hydroxyl (OH-) while DNA contains deoxyribose sugar.
RNA contains four nitrogenous bases cytosine, adenine, guanine, and uracil, while DNA contains cytosine, adenine, guanine, and thymine.
Double helix means two stranded structure like DNA, while RNA is single stranded.
DNA molecule is much longer polymer than RNA molecule.
The value chain, Panera Bread's value chain has several component to its value chain, customer service, operating performance, and most important being inbound logistics. The most important for Panera Bread is the Priority on inbound logistics, as it is what differentiates their product from their competitors, which is their most important competitive advantage.
B) cortisol ensures that the brain has glucose when it’s necessary. Cortisol is a steroid hormone that helps control blood sugar levels, metabolism, and inflammation. Glucose, also known as sugar, is an energy source used in cells in the body. The brain is highly demanding of energy since it is so rich in nerve cells and neurons, so glucose is essential to the brain. Too much can harm the brain though, so it is important for the cortisol to control the sugar levels.
