Answer: Option A
Explanation:
A tunicate is marine invertebrate animal which is a part of chordates. They have notochords and dorsal nerve chord. The subphylum of the organism is called as Urochordata.
The adult urochordates lack notochord but the larval stage of the urochordates have notochord. This is because it helps in swimming of the organism which is required only at the larval stage.
The adult stage of the tunicates is sessile and they do not swim so they do not require notochord.
The question is simply asking for the volumetric flow rate of the water in the river. It<span> is the volume of fluid which passes per unit time. It has units of m^3 /s. We calculate as follows:
Q = 750 m^2 (4 m/s ) = 3000 m^3/s
Hope this answers the question. Have a nice day.</span>
The Bartholin's Glands, which are also known as the vestibular glands are a pair of pea size gland. The location of the Bartholin's gland is postrior to the vaginal orifice.
The main function of these Bartholin's gland is to secrete mucus and to lubricate the vaginal orifice. These gland is homologous to the bulbourethral glands present in the males.
<h3>Hence, the vaginal orifice is lubricated by secretions from the Bartholin's Glands.</h3>
Interphase: You could not distinguish any parts of the cell.
Prophase: You could clearly see the chromosomes throughout the cell.
Metaphase: The chromosomes where lines up in the middle of the cell.
Anaphase: You could see the chromosomes were separated to ether side of the cell.
Telophase: The entire cell was separated to each side but was not split into its own cell.
Cytokinesis: In this step the cell had totally separated and there was now two separate daughter cells.
The atmosphere is the part of the carbon and water cycles but absent from the phosphorous cycle. Carbon cycle depends on photosynthesis and respiration. Water cycle connects aquatic and terrestrial biomes.
