The force of attraction between two objects is gravity (gravitational pull) so I believe that the answer is (b. universal gravitation).
All the correct options are given below:
flagellated spores,
important in digestion of animals,
can cause disease in plants
can cause disease in animals
The Chytridiomycota is the oldest phylum of kingdom fungi. It is also called chytrids. Members of this phylum have motile spores. Each spore has one whiplash flagellum at the posterior end. Chytrids can live as parasite algae species to large plants and microscopic worms to amphibians. The disease caused by the chytrid <em>Batrachochytrium dendrobatidis</em> killing large number of frogs. The symbiotic chytrids in the cows help in breaking down of plant material in their gut during digestion.
Answer;
-In the smooth ER
In certain kinds of muscle cells, calcium ions are stored in the smooth ER.
Explanation;
-The smooth endoplasmic reticulum is the part of the endoplasmic reticulum (ER) which does not have ribosomes bound to it, thus not exhibiting the bumpy appearance shown by the rough endoplasmic reticulum.
-The smooth ER is important in the synthesis of lipids, such as cholesterol and phospholipids, which form all the membranes of the organism. In addition it is important for the synthesis and secretion of steroid hormones from cholesterol and other lipid precursors.
Answer: I don't understant the question.
