Answer: False

Explanation: The phylum Chordata (chordates) includes two other subphyla: Cephalochordata (e.g. lancelets) and Urochordata (e.g. tunicates). Both subphyla encompass organisms which do possess a notochord and a dorsal nerve cord, lost after the embryonic stage or otherwise.

What Is Chemogeny ( Chemical Evolution ) ? And Explain The Steps Of Chemogeny [Both Answer In Simple Word/ Simple Answer Which I
solniwko [45]

Answer:

Chemogeny may be a theory of chemical evolution that depends on the chemical reactions and formation of drugs on the bases of chemical reactions. This theory says that “Life occurs as a results of evolution of inorganic matter”.

In the 1920's Scientists Oparin and Haldane, developed this hypothesis of the chemical origin of life from the primitive atmosphere of the world having matter like methane, ammonia and water. there have been very low concentrations of oxygen thanks to the presence of high temperatures like 5000-60000C. So, these conditions weren't suitable for the free existence of organic compounds, so reactions started happening .

Under conditions like high sunlight and warmth , inorganic matter gets converted to inorganic compounds. And this might end in the storage of organic compounds, which gets more and more concentrated with the passage of many years.

These compounds interact with one another and end in “life”.

So, chemogeny is that the process of chemical evolution of earth and formation of life from pre-existing matter with the assistance of chemical reactions.

arrange the process of hemostasis in sequence. (separate letters by a comma and space [ex. a, b, c,…])
Nina [5.8K]

The sequence for the process of hemostasis is A, F, B, C, D, E.

<h3>What is Hemostasis?</h3>

Your body's natural response to an injury, hemostasis, stops the bleeding and repairs the damage. This skill typically works to your advantage by preserving blood and avoiding infections. The process can occasionally malfunction, leading to issues with excessive or insufficient clotting. There are four distinct steps to the hemostasis mechanism.

1) Blood vessel constriction.

2) The development of a transient "platelet plug."

3) The coagulation cascade is activated.

4) The last clot, or "fibrin plug," forms.

A series of enzymatic activations that result in the development of a clot containing platelets and fibrin polymer are made easier by hemostasis. While the process of tissue regeneration is taking place, this clot plugs the wounded area, manages the bleeding, and stops further bleeding.
