Recent advances in technology have made vegetarian meals far cheaper to produce. Assuming that vegetarian meals and beef aresubstitutes, what would be the expected change in the demand for beef, ceteris paribus? (1 point)
It is impossible to tell from the information provided.
The demand for beef would increase.
The demand for beef would decrease.
The demand for beef would be unaffected.
Check Answer

Answers

The demand for beef would be unaffected be the expected change in the demand for beef, ceteris paribus. The correct option is C.

Thus, Consumers might be more likely to pick vegetarian options over beef due to cost considerations.

As a result of recent technological advancements that have made vegetarian meals more affordable to manufacture.

All else being equal (ceteris paribus), this shift in consumer preferences brought on by the relative affordability of vegetarian meals is expected to lead to a decline in the demand for beef.

Thus, The demand for beef would be unaffected be the expected change in the demand for beef, ceteris paribus. The correct option is C.

Unlike weather, climate

Answers

Climate is best described as C. THE LONG-TERM AVERAGE OF WEATHER VARIATIONS IN A SPECIFIC AREA.

The long term average being 30 years. These weather variations are affected by the temperature, precipitation, and wind.

Climate determinants include latitude, altitude, proximity to mountains and oceans, proportion of land to water, thermohaline circulation of the ocean, ocean currents, density and type of vegetation present in an area, as well as the areas' water retention and rainfall.

Climate are classified into three groups. These are Bergeron and Spatial Synoptic, Koppen, and Thornthwaite.

How are cis-trans isomers used for night vision?

Answers

Answer: 11-cis Retinal is the light-sensitive component of rod and cone photoreceptors, and this structural conformation in rod photoreceptors is vital for low-light vision (night vision)

Explanation: To detect light, photoreceptors (especially rods) employ the exceptional properties of 11-cis retinal. Rods transmits low-light vision, as only them have enough sensitivity to respond and to trigger vision .

11-cis retinal in rods are bound to an opsin signaling protein to form a visual pigment molecule. Its other isomer, the all trans retinal is isomerized to 11-cis retinal causing the branching of the polyene chain, deactivating opsin molecule and increasing sensitivity to light. This adaptation occurs rapidly in minutes in the dark, resulting in maximum sensitivity to light.

"Cis-Trans Isomerism in Vision
The retina, the light-detector layer in the back of our eyes, contains colored compounds called visual pigments. They are insoluble in water and can be extracted from the retina with aqueous detergents. In the dark these pigments are reddish (their name, rhodopsin, comes from a Greek word meaning rose-colored), but the color fades upon exposure to light.

Rhodopsin molecules contain a protein called opsin plus a derivative of vitamin A called 11-cis-retinal. In the dark, 11-cis-retinal fits nicely into the folds of the surrounding opsin. When light hits the rhodopsin, the 11-cis-retinal becomes all-trans-retinal and no longer fits into the cavity of opsin. The opsin and the all-trans-retinal separate. The change in rhodopsin conformation is eventually transmitted to the nerve cells in the eye and then the brain. The stereoisomerism of retinal is thus an important part of the vision process. Note that only one of the five double bonds is affected in this transformation, but when this one changes from cis to trans, the shape of the entire molecule changes. An enzyme later catalyzes the change of all-trans-retinal back to 11-cis-retinal so that it can once again bind opsin and wait for the next exposure to light.

The retinas of vertebrates have two kinds of cells that contain rhodopsin. These cells are distinguished by their shapes: rods and cones. The cones, which function in bright light and are used in color vision, are concentrated in the central portion of the retina, called the macula, and are responsible for the greatest visual acuity. The remaining area of the retina consists mostly of rods, which are used for peripheral and night vision. 11-cis-retinal is present in both rods and cones. However, the opsin is somewhat different in the two kinds of cells, and the cones have three different opsins, one kind each for perception of blue, green, and red colors."
