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.
Answer:
Typically, the nucleus is the most prominent organelle in a cell (Figure 1). The nucleus (plural = nuclei) houses the cell's DNA in the form of chromatin and directs the synthesis of ribosomes and proteins.
Explanation:
Scientists use a two-name system called a Binomial Naming System. Scientists name animals and plants using the system that describes the genus and species of the organism. The first word is the genus and the second is the species. The first word is capitalized and the second is not.
Answer:
Explanation:
bacteria with No Plasmid -----------------will grow ONLY in medium without ampicillin.
"nonrecombinant gene, recombinant plasmid with vgp gene,", recombinant plasmid but no vgp gene-----------------------will grow in both media".
it means Plasmid have ampicillin resistance gene. So if we use medium with ampicillin so it will allow the growth of only those bacterai which have transformed plasmid (containing amp resistance gene).
so having gene or not, recombinant or recombinant dosnt matter, all the other s will grow in both type of medium as far as plasmid is transformed in to it.
Answer:
In myopia the image is focused ahead of the retina. While in Hyperopia the image is focused beyond or behind the retina.
Explanation:
I'll start by defining the two key terms, Myopia and Hyperopia. Myopia is otherwise called short-sightedness. It is a condition where one cannot see the images of objects located far away from the eyes and tend to see images within a short distance from the eyes. Hyperopia on the otherhand is otherwise known as long-sightedness. It is an eye defect which manifests by one not seeing objects close to the eyes instead he or she see only objects far from the eyes. These two eye defects are a malfunction of the accomodation feature of the eye.
Normally when an object is viewed all the parts of the eye (the organ for vision) function to focus the image of that object on the retina but especially on a part of it called the *light spot*. This then translates the image to the brain using the optical nerve. The brain then interpretes what is being viewed
However in Myopia, images are focused ahead of the retina . This is as a result of the eyeball being too long in relation to the focusing power of the cornea and eye lens.
In Hyperopia on the other hand, images are focused behind the retina. This is by the diameter of the eye being too short or the cornea being too flat.
In conclusion, from the above stated points,it is glaring that Myopia and Hyperopia affect the lens's ability to focus images on the retina.
