Answer:

lateral inhibition in the retina

Explanation:

Horizontal cells are in contact with photoreceptor cells through the synapse. One photoreceptor forms an excitatory synapse with horizontal cell in the adjacent regions of the retina while the horizontal cell forms an inhibitory synapse with another photoreceptor.  

Hence, as one photoreceptor activates the horizontal cell, the horizontal cell, in turn, inhibits the other photoreceptor cell and thereby reduces the quantity of neurotransmitter released at the bipolar cell. In this way, horizontal cells transmit lateral inhibitory stimulus to the photoreceptor which in turn improves the contrast at the edges of the object.

Arrange these groups in order from most inclusive (most general) to least inclusive (most specific).
LUCKY_DIMON [66]

These groups are arranged in order from most inclusive (most general) to least inclusive (most specific) is gnathostomes, osteichthyans, lobe-fins, tetrapods, amphibians.

<h3>What is gnathostomes?</h3>

The jawed vertebrates are called gnathostomata. The phrase comes from the Greek words "jaw" and "mouth." Approximately 60,000 species make up the diversity of the gnathostome, which represents 99% of all vertebrates still alive today.

<h3>What is osteichthyans?</h3>

A broad taxonomic group of fish called osteichthyes, also known as the "bony fish," has skeletons that are predominantly made of bone tissue.

<h3>What is lobe-fins?</h3>

The taxon Sarcopterygii, also known as Crossopterygii, is made up of bony fishes noted for having lobe-finned fishes as its members.

<h3>What is tetrapods?</h3>

Four-legged vertebrates that make up the superclass Tetrapoda are known as tetrapods, which derives from the Ancient Greek (tetra-) "four" and "foot." It consists of synapsids, dinosaurs, and extinct as well as living amphibians, reptiles, and dinosaur-related birds (including mammals).

Which of the following sequences is correct for the downhill movement of electrons during cellular respiration? A. glucose – cit
Volgvan

Answer:

B. glucose – NADH – electron transport – O2

Explanation:

This is the sequence  from glycolysis in which  glucose molecules are split down to pyruvate, to oxidative phosphorylation.

During this process the electrons are released from glucose  molecule as it is oxidised multiple times as pyruvate, and other molecules formed subsequently in Kreb's cycle, until the oxidative phosphorylation is reached .

The makes the  carrier molecules to be reduced.Thus NAD→NADH,FAD→FADH .

The electrons from above are  transferred in hydrogen atoms  to matrix by these co-enzymes.Where the H is split to electrons  and protons.

The electrons for the ETC, produce the PMF for transporting  protons into the intramembrane space.

The concentration of protons generated the electrochemical gradients  which is needed to produce energy for for phosphorylation of ADP with Pi to form ATP by ATpase synthase.

The electrons moves as chain,and this is finally accepted by oxygen as the final electron acceptor.
