Amblyopia, optic neuritis is a dimness of vision or the partial loss of sight without detectable disease of the eye.

Partial blindness means you have very limited vision. Complete blindness means you cannot see anything and do not see light. Decreased vision in one or both eyes without detectable anatomic damage in the eye or your vision.

Temporary vision loss (total or partial) can also be the result of migraine headaches, sickle cell anemia, also referred to as sickle cell disease (inherited blood condition) acute angle-closure glaucoma (sudden rise in eye pressure).Types of vision loss include central vision loss or difficulty seeing things in the center of vision. Peripheral vision loss, or difficulty seeing things out of the corner of the eyes.

A species that is no longer in existence would best be characterized as which of the following?

Gnesinka [82]

Answer:

Extinct.

Explanation:

The IUCN red list classifies the organism as endangered , extinct, threatened and vulnerable organism. The organism are classified on the basis of their number and presence on the particular area.

Extinct species is the species that are no longer present on the earth. The extinct species has been eliminated due to the unfavorable environmental condition and due to human activities. No single organism is present of the extinct species.

Thus, the correct answer is option (3).

1. Explain the relationship between heat and<br> thermal energy.

shutvik [7]

Answer:

Thermal energy refers to the energy contained within a system that is responsible for its temperature. Heat is the flow of thermal energy. A whole branch of physics, thermodynamics, deals with how heat is transferred between different systems and how work is done in the process (see the 1ˢᵗ law of thermodynamics).

Interactions between Na channels and Na -HCO3- cotransporters in the freshwater fish gill MR cell: a model for transepithelial N

Galina-37 [17]

Using intracellular pH (pHi) imaging, we investigated Cl transport mechanisms in freshwater rainbow trout gill mitochondrion-rich (MR) cells. In isolated MR cells, scanning electron microscopy has shown that cellular polarity is maintained.

<h3></h3><h3>What is Transport in Two Species of Freshwater Fish?</h3>

Large amounts of diluted water constantly flow across the gill epithelium of freshwater fish, causing them to experience an ionic stress. Since the mechanisms of ion and acid-base transport are connected at the gill, this is made worse by an acid-base disruption. Active transport at specialised mitochondrion-rich (MR) cells on the gill surface helps the fish maintain homeostasis. As a result, the freshwater gill has served as a crucial model system for figuring out the transport processes that allow for the overriding of adverse ion gradients. Numerous research have tried to clarify the mechanisms of ion and acid-base transport in freshwater fishes during the past ten years using a range of methodologies.
