The first thing that the farmer should do is formulate a hypothesis in which he will make intelligent guesses on what is happening or develop a theory of which would explain what is happening. It is the first step in scientific investigation in order to formulate questions of why weeds that are sprayed does not die. After this, it is only then the farmer should experiment and after that, he should finalize his findings as it is its conclusion to the problem.
It is necessary for the pancreas to secrete a high pH solution into the intestine in order to neutralize the acidity of the processed food particles [chyme] that are passed into the intestine and to provide a suitable pH for the enzymes in the intestines that will act on the processed food particles.
It’d be at least 70 million years.
Answer:
it causes the depolarization of the target cell
Explanation:
Glutamate is an excitatory amino acid neurotransmitter that binds to specific receptors on the surface of target cells and thus causes its depolarization. During glutamate-mediated depolarization, the difference in charge inside and outside the cell is lost due to the entry of sodium and calcium positive ions into the postsynaptic cell (neuron) through specific ion channels. Moreover, glutamate binding also leads to the exit of potassium ions from the cell, thereby resulting in excitation. Through this mechanism, glutamate regulates many signaling pathways, such as those involved in memory, learning, emotions, cognition, motor control, etc.
Vacuole: is a cavity in the cytoplasm of a cell that contains inorganic or organic material such as fluid, food, or waste.
lysosome: are organelles that contain digestive enzymes. They digest excess or worn out organelles, food particles, and engulfed viruses or bacteria.
Mitochondria: is the "powerhouse" of the cell. They take in nutrients, break it down, and creates energy rich molecules for the cell.
cell membrane: protects the cell from its surroundings. It consists of a layer of lipid bilayer with embedded proteins.
I really hope this helps:)
