What 4 features do all chordates have?
All chordates share some structures during at least some stage of their development. These are the notochord, nerve cord, pharyngeal slits, and tail.
What are chordates?When talking about chordates we are referring to the chordate phylum. Individuals composing this group share four main structures,
Notochord
The notochord is a dorsal spine precursor from which the nervous system gets formed.
The notochord is present during the whole individual's life (like some tunicates) or during only the embryonary period (like vertebrates).
Nerve cord
The nerve cord is dorsally located, together with the notochord.
It is hollow, and, during embryogenesis, it might differentiate into a brain.
This cord connects external stimuli to the motor system to react to them.
Pharyngeal slits
Present only during a period of the embryonary stage. These slits give rise to different organs and structures like tonsils, ears, or gills.
Tail
All chordates have a tail in at least a period of the organism's development.

What is the name of the Coenzyme that binds with Acetyl Acid?
The name of the coenzyme is Coenzyme A.
Citric acid cycleThe intermediate step between glycolysis and the citric acid cycle is the production of acetyl-co A.
Acetyl-co A is produced by the oxidative decarboxylation of the pyruvate molecule generated from glycolysis in the matrix of the mitochondrion.
The pyruvate molecule is first transformed into an acetyl group. The enzyme, Coenzyme A, binds with the acetyl group to form acetyl-co A.

Answer:
sensory receptors in the skin detect the stimuli from the environment
Explanation:
Select the correct answer from each drop-down menu.
The nervous system and the muscle system respond to stimuli to produce motion. The movements of
muscles are mostly voluntary. Involuntary movements occur in these muscles when the nerve impulse passes from a sensory neuron to a motor neuron via an interneuron in the
.
The nervous system and muscular system respond to stimuli to produce movement.
What is nervous impulse?
The nerve impulse corresponds to an electrical current that propagates through neurons, thanks to a process of membrane depolarization. This depolarization process occurs through stimuli and its function is to transmit certain information to other cells (nervous, muscular or glandular).
With this information, we can conclude that the nervous system and muscular system respond to stimuli to produce movement.

In chloroplasts there are structures known as thylakoids. The membrane that forms a compartment inside the stroma is the thylakoid membrane.
What is the chloroplast structure?The structure of these organelles is as follows,
Chloroplasts are limited by an outer membrane and an inner one. In between the two membranes, there is a space left called intermembrane space. In the interior of the inner membrane, there is another space known the stroma. Within the stroma, there is the third system of membranes, known as thylakoids. Thylakoids are disk-shaped structures limited by a membrane, and in their interior, there is a space named thylakoid space.These structures are arranged as piles, receiving the name of grana. Grana connects by a larger thylakoid membrane. The photosynthetic pigments are placed in the thylakoids, where occurs light-dependent reactions.According to this description, the membrane that forms a compartment inside the stroma is the thylakoid membrane.

What are the contributions of each of these scientists to the cell theory? And how did that information contradict what was believed or accepted at that time?
M.J. Schleiden-
Louis Pasteur-
Rudolf Virchow-
M. J. Schleiden:
In the year 1838, a German botanist presented the first cell theory (Although his theory was ultimately disproved, it did contribute to a change in scientific focus to cellular processes.)
What is cell?All living creatures and body tissues are made up of the smallest unit that can live on its own. The cell membrane, nucleus, and cytoplasm are the three primary components of a cell. The cell membrane encloses the cell and regulates the molecules that enter and exit it.
His theory: Cells make up all plant tissues, and an embryonic plant is made up of just one cell. He declared that the cell is the fundamental building block of all plant matter.
Louis Pasteur- 1855 - German physiologist, physician, pathologist; and anthropologist. Added a third to the cell theory: Omnis Cellula e cellula (all cells develop only from existing cells).- Implied that there was no Spontaneous generation.
Rudolf Virchow- In 1862 he conducted a famous experiment supporting the theory that cells can only come from other cells.
His experiment:
Steralized flasks with straight and curved necks were used to heat nutrient broths. Bacteria only developed in the straight necks because bacteria cells from the air settled in the S-shaped necks' curves. Spontaneous gen did not produce proven cells in the broth.

According to this theory, it was believed that dust creates fleas, maggot arises from the rotten meat, wheat and bread left in the dark corner producing mice.
Louis Pasteur was the first scientist to prove that cells originate from pre-existing cells.
Rudolf Virchow proposed that Omnis cellula e cellula, which means each cell comes from another cell.
