Answer:

A: Nematodes

Explanation:

Nematodes are a subdivision of the animal kingdom known as Nematoda. The group consists of round/cylindrical worms without body segments. They are mostly microscopic, bilaterally symmetrical with a wide range of habitat. Many of the species in this group are endo-parasites of man and other higher animals.

The flatworms belongs to the Platyhelminthes phylum. They are unsegmented and parasites of other animals just like nematodes. However, they are flat in shape as opposed to cylindrical shape of nematodes.

Earthworms belong to the phylum Annelida. They are segmented with nervous system.

In this case, the Trichinella worms seem to be most similar to Nematodes in that:

  • <em>They have cylindrical bodies</em>
  • <em>They are unsegmented</em>
  • <em>They are parasitic in nature</em>

The correct option is A.

The ionic group coo- on succinate forms bonds with the succinate dehydrogenase
Dmitriy789 [7]

At neutral pH, the ionic group COO- on succinate makes bonds with the active site of succinate dehydrogenase. This bonding is required for succinate oxidation.

<h3>What is succinate oxidation?</h3>

In the Krebs cycle , succinate dehydrogenase catalyzes the oxidation of succinate to fumarate, with the resulting electrons being supplied to respiratory chain complex III to decrease oxygen and produce water.

SDH oxidizes succinate to fumarate during the citric acid cycle. SDH is structurally similar to fumarate reductase, an enzyme that catalyzes the opposite process during anaerobic respiration in bacteria.

Len [333]
The parcelization and urbanization of forests bring with them serious consequences for nature and humans beings, although we probably see it as an advance; deforestation, logging, burning, seriously affect the vegetation, and the fauna of a forest, the human workforce , the deviation of rivers and the modification of natural zones seem to be a development of society, but in the long run it affects more to humans than to nature itself, because we are the ones who will not have natural lungs to breathe, and those who soon will be drowned with our own pollution, because there are no forests, no nature to purify the air we need.

The gastric phase of gastric secretion is triggered by the:
Anvisha [2.4K]

Answer:

The entry of food into the stomach.

Explanation:

Gastric secretion is triggered by the act of eating which is called as reflex phase and the entry of food into the stomach called a gastric phase. The entry of the food particles into the small intestine also helps to control the secretion of gastric called an intestinal phase.

The secreted fluid in the small intestine contains some ions, acids, etc such as pepsinogen, intrinsic factor, bicarbonate, hydrochloric acid, and mucus. The reflex phase or cephalic phase helps to stimulate parasympathetic neurons that release acetylcholine chemical, then it produces the higher secretion of gastric juice.
