The question is incomplete as it does not have the options which are:

Protein carrier

Lipid carrier

Porin carrier

All of the choices are correct

Answer:

Protein carrier

Explanation:

The transport of molecules through diffusion can be passive or facilitated. The facilitated diffusion in which the molecules are facilitated to cross required tow type of protein channels which are the channel proteins and the carrier proteins.

The carrier proteins are the transmembrane proteins which are specific for ions and to transport the molecules change their shape of conformation. The change in the shape is responsible for the release of ions on the other side of the membrane.

Thus, Protein carrier  is correct.

Which of the following options lists the stages in cellular respiration in the correct order? glycolysis, the citric acid cycle,
marishachu [46]

Answer:

The correct answer is  glycolysis, the citric acid cycle, and oxidative phosphorylation

Explanation:

Aerobic respiration contains three major processes that are glycolysis, the citric acid cycle, and oxidative phosphorylation.  

In glycolysis, partial oxidation of one mole of glucose gives two moles of pyruvate and 2 NADH and 2 ATP. Then this pyruvate is converted into acetyl-CoA in the mitochondrial matrix(in eukaryotes) and acts as a fuel for the Krebs cycle.

In the Krebs cycle, acetyl CoA gives rise to 4 CO₂, 2 ATP, 6 NADH, and 2 FADH₂. So from glycolysis and Krebs cycle, only 4 ATP is produced and most of the energy remains in the form of NADH and FADH₂.

So in oxidative phosphorylation electrons are released from these molecules into machinery of oxidative phosphorylation to synthesize ATP.

More solar energy reaches the equatorial regions than the polar regions because the equatorial regions
crimeas [40]


The answer is that the equatorial regions receive sun rays closest to the vertical (direct rays) because of their position relative to the equator where the tilting of the earth only mildly affects the climate. The climate along the equator  changes very little through out the year and has summer like conditions for  most of the year.

However the other regions may receive direct sun rays but for far more limited periods.  In the months of July and August (summer months), the northern hemisphere is tilted towards the sun and receives the most  direct  rays. The opposite occurs in December and January when it is tilted away from the sun and thus winter sets in, whereas the southern hemisphere is at this time tilted toward the sun and receives the most direct sun rays.

Crop monitoring makes use of space-based data to keep tabs on crop development and forecast crop yields for certain fields that have been planted.

<h3>What is monitoring systems?</h3>

A system for monitoring agriculture consists of a network with wireless sensors. These sensors gather information from several nodes positioned on the playing surface. Then, specialists or nearby farmers analyze this data. The data can be used to make a number of inferences about weather patterns, soil fertility, crop quality, etc. A system is developed for agricultural field monitoring in IoT-based modern agriculture with the aid of sensor like light, humid, temperatures, soil moisture, etc. Farmers may monitor the condition of thier fields from any location. IoT-based smart farming is considerably more efficient than conventional farming.

<h3>How do farmers monitor their crops?</h3>

Nowadays, satellite techniques are widely employed in agriculture, and many farmers use them frequently to observe their fields and assess the condition of their crops. Crop monitoring is crucial for managing various pests, weeds, and diseases that affect crops. This gives information about the crop's current situation, and you can then look ahead in time to forecast what will probably be the crop's next problem.
