The fertilized part of a flower is called an ovary
All characteristics of life rely on the sun.
Answer:
fluid-filled cavity
Explanation:
Rhynchocoel is a fluid-filled tubular cavity present in the organisms of the phylum Nemertea. This cavity lies above the intestines of these organisms in the lower body.
Nemertea is a phylum composed of worms that can be found in shallow water.
These worms have already been classified as a branch of the Flatworms (such as Planarians), with which they are often confused. But recent embryological and molecular evidence points to a phylogenetic relationship with mollusks and annelids. They remind the Flatworms to be non-segmented flat worms. But unlike these, they have a complete bowel with mouth and anus, and a closed vascular system. The article on Planarians can be accessed here.
• Matthias Schleiden observed that all plants were made of cells; Theodor Schwann observed that all animals were also made of cells; and Rudolf Virchow observed that cells only come from other cells.
• Prokaryotic cells- don’t contain a nucleus or any other membrane-bound organelle.
Eukaryotic cells- contain membrane-bound organelles, including a nucleus.
• Phospholipids make up the basic structure of a cell membrane and are arranged in a double layer called the lipid bilayer.
• Active Transport- moves ions from low concentration to high, using metabolic energy in the form of ATP.
Passive Transport - moves ions from high concentration to low, using no metabolic energy.
Answer:
The correct answer will be-False
Explanation:
Calcitonin is a hormone produced by the parafollicular cells present in the thyroid gland.
The Calcitonin plays an important role in the human body as they reduce the level of phosphate and calcium in the blood.
The calcitonin is produced by the C-cells in response to the amount of the calcium levels in the blood as a high concentration of calcium cause release of calcitonin.
Since the calcitonin is involved in the regulation of calcium of blood and not bones therefore, false is the correct answer.
