Two factors contributed to the success of the pteridophytes: the extreme miniaturization of the gametophytic generation and an important development of the sporophytic generation (development of the tree forms).
Pteridophytes are a group of plants that peaked in the Carboniferous (-300 million years). It is the first great terrestrial plant civilization. These plants would have appeared in the Devonian -400 million years ago, perhaps from certain primitive terrestrial plants which, unlike bryophytes, would have favored the diploid generation on the haploid generation.
Particularly well adapted to terrestrial life, they have created, thanks to the development of tree forms, immense forests whose fossilization is at the origin of coal deposits.
Pteridophytes are at the origin of an evolutionary lineage based on the extreme miniaturization of gametophytic generation and an important development of sporophytic generation, leading to all tracheophytes including current flowering plants. Pteridophytes are well adapted to terrestrial life, however fertilization still requires the presence of water since male gametes are swimmers.
Assuming that all of them was made without sugar, Butter beans has the most amount of carbohydrates the options above
100 gram of butter beans contains about 21 gram of carbohydrates. This is way more than tuna and fruits who contains 0 carbs and protein that only contains 1.1 gram.
Wouldn't it be three because of allthe types of Fungi?
Answer:
Exocrine glands secrete sweat and oil while endocrine glands secrete hormones.
Explanation:
As she knows the endocrine and exocrine glands in respect of their origin from skin, so our answer must be related to the skin so that she can understand easily. So our answer should be as follows -
- Endocrine glands are those glands which secrete hormones directly to the blood stream but exocrine glands are those glands which secrete sweat and oils directly to the skin surface.
- A duct is often present in exocrine glands but endocrine glands lack ducts.
Plato answer:
Stimulation of a neuron causes a change in the charge inside the cell from negative to positive. This change is caused by ions, which are atoms with an electrical charge, moving across the cell. This change within the cell is consistent with the definition of an electric charge.
