Nervous control of gastric secretion is provided by the vagus nerve and enteric plexus. The correct option is D.
Gastric secretion refers to the juices and acids that are secreted by the gastric area of the body. These juices and acids are secreted to digest the food material.
Our body's all function are controlled by the nervous system. Digestion is also controlled by the nervous system. The nervous systems include the spinal cord and brain.
The vagus nerve and enteric plexus are responsible for the secretion of digestive juices and acids. The enteric plexus is coming out from the ventral part of the brain stem. The vagus nerve work for carrying the axons to the gastrointestinal tract.
Thus, the correct option is D. the vagus nerve and enteric plexus.

Gastric secretion is controlled by the vagus nerve and the enteric plexus, part of the autonomic nervous system that directly influences digestive functions. When activated by a stretch receptor, a postganglionic parasympathetic neuron within the stomach's smooth muscle fibers initiates a contraction for digestion.
The nervous control of gastric secretion is provided by the vagus nerve and enteric plexus. This is part of the autonomic nervous system, the nervous tissue that is part of the digestive system. The enteric nervous system, which refers to the digestive organs, has plexuses that can directly influence digestive functions. When the stomach is filled, a neuron connected to the stomach's smooth muscle fibers, activated by a stretch receptor, initiates a contract, allowing the stomach to digest excessive food. This neuron is a postganglionic parasympathetic neuron controlled by a fiber found in the vagus nerve.

A. Increases
B. Decreases
Answer:
B
Explanation:
Answer:
Early organisms in the precambrian era converted ___Carbon dioxide__ to oxygen.
Explanation:
THE PRECAMBRIAN ERA:
The word Precambrian means before the Cambrian period. Before the formation of oldest rock with having fossils in them this term was used to the whole period of earth's history.
This era gone through number of important changes. One important change is that atmosphere of this era is deprived of Oxygen. All other content of the atmosphere is same as component of air present today but with little water vapours. Early organisms in the precambrian era converts carbon dioxide into oxygen. This oxygen was very less and begins to combine chemically with iron and other elements. This produces great mineral deposits around the world. This is the era from where aerobic respiration organisms start their life cycles.
B. the scientific process in which all claims must be rooted in well-established biological evidence.
C. the process by which researchers seek to develop new theories by paying close attention to the available data.
D. mechanisms for which activity is influenced by thoughts provided by the individual.
Bottom-up mechanisms in psychology refer to processes that are primarily driven by incoming stimulus information, starting from lower-level sensory data and working up to higher-level cognitive functions.
The 'bottom-up' or 'data-driven' mechanisms are A. mechanisms for which activity is primarily triggered and shaped by the incoming stimulus information.
This means that information processing starts with the stimuli that reaches our senses and then proceeds to the higher-level cognitive processes. In other words, we begin our perception by witnessing an event and the sensation driving our processing, rather than being directed by prior knowledge or expectation.
On numerous occasions, our brains begin to process data at very fundamental levels and then move on to more complex analytical thinking, which can be signified as bottom-up processing.

Bottom-up (or data-driven) mechanisms are mechanisms for which activity is primarily triggered and shaped by the incoming stimulus information. These mechanisms operate by processing sensory inputs in a sequential and incremental manner to build a higher-level representation or understanding.
Bottom-up (or data-driven) mechanisms are mechanisms for which activity is primarily triggered and shaped by the incoming stimulus information. These mechanisms operate by processing sensory inputs in a sequential and incremental manner to build a higher-level representation or understanding. They are commonly observed in biological systems, such as neuronal processing in the brain or sensory perception. For example, when you touch a hot object, your sensory receptors in the skin send signals to your brain, triggering a cascade of physiological responses to remove your hand from the source of heat.

Answer: Ella came to the conclusion the cells were a plant because plant cells are rectangular, and it has a central vacuole to store food and water, it would also contain a cell wall and a cell membrane. I think that Ella is correct if she saw all these things through her microscope. Plant cells contain an organelle called chloroplast, and this organelle has chlorophyll which supports photosynthesis. So yes, Ella is correct.
the water cycle
uneven heat distribution
even pressure distribution
Answer: Option (c) is the correct answer.
Explanation:
Wind circulation is defined as the flow of air from one place to another. This occurs due to uneven heating of air as increase in temperature raises the kinetic energy of molecules. As a result, warm air moves more rapidly.
Whereas in cold air molecules do not have enough kinetic energy. Hence, they move at slow speed.
Therefore, we can conclude that the main reason for wind or air circulation is uneven heat distribution.
