Glucose is a carbohydrate formed by using energy from the sun to convert carbon dioxide and water into glucose molecules through a reaction called photosynthesis.
Photosynthesis is the process by which plants use carbon dioxide, water, and energy from the sun to convert it into oxygen and sugar molecules called glucose. Plants use their organelles called chloroplasts to store energy from the sun. Chloroplasts have thylakoid membranes that possess a pigment known as chlorophyll. Chlorophyll is responsible for giving green color to plants.
Photosynthesis can be divided into light-dependent and light-independent reactions. Light-dependent reactions take place in the stroma, the space between thylakoid membranes and chloroplast. It uses light energy from the sun to convert into chemical energy in the form of ATP and NADPH. ATP and NADPH provide energy to assemble sugar molecules, synthesized by photosynthesis, called glucose.

Distinguish the overall structure of a gastrovascular cavity from that of an alimentary canal.
The gastrovascular cavity is the area where food is both ingested and expelled. Different structures, such as the mouth and anus, are included in an elementary canal for the purposes of ingesting and expelling food.
The gastrovascular cavity refers to the highly branching digestive tract found in coelenterates and flatworms. The mouth is there, but the anus is lacking, indicating that this digestive system isn't complete. Additionally, chemicals are expelled by the mouth. The majority of coelenterates have tentacles around their mouths to collect prey, and they digest their food in a blind sac or gastrovascular cavity. Diffusion is the method used to exchange nutrients. Higher organisms have an alimentary canal. In annelids, the entire digestive system or alimentary canal has formed. Food should be consumed through the mouth, and waste should be expelled through the anus. The mouth, stomach, pancreas, and intestines are all parts of an animal's digestive tract, including those of humans. Digestive juice is produced by the intestinal glands, liver, pancreas, and other organs.Learn more about the gastrovascular cavity with the help of the given link:

A ______ is a sensor that monitors the environment and responds to changes by sending information along a pathway to a control center.
A receptor is a sensor that monitors the environment and responds to changes by sending information along a pathway to a control center.
In the field of biology, a receptor can be described as the part of the body that detects a change in the external environment. Receptors are usually nerve endings present in the sensory organs of the body. For example, when your hand touches something hot, the nerve endings of the skin of your hand detect it.
The sensory receptors, after detecting changes in the external environment, send signals to the control center of the body. The control center is the central nervous system of which the brain and spinal cord are a part.
The control center interprets this information and sends a response through the effector motor neurons.

Prokaryotic mrna may code for more than one protein and are called polycistronic whereas eukaryotic mrna are ________________.
Prokaryotic mRNA may code for more than one protein and are called polycistronic whereas eukaryotic mRNA are monocistronic.
Proteins are made when information from the DNA is transferred to mRNA which in turn makes the proteins.
In the case of prokaryotes, a single mRNA protein can code for multiple proteins. Such a phenomenon in which a single mRNA transcript codes for multiple proteins is referred to as polycistronic.
In the case of eukaryotes, a single mRNA transcript codes for only one protein. Such a in which a single mRNA transcript is involved in the formation of a single protein is referred to as monocistronic.

This group of species became known as "Darwin's finches". In his observations, Darwin saw that variation and selection produced adaptations not only in the structure of the feet, but also in the shape and size of the beaks. He also noted that seeds were the main diet of ground-dwelling finches.due to the likely scarcity of food, the teeth must have a bigger beak to get food in more difficult places.
Why do finches have different beaks?During his expedition to the islands, Darwin noticed that different types of finches had beaks of different sizes and shapes, adapted to different types of food in the different ecological niches they occupied in the Galapagos Islands.

structure of az-dna with two different backbone chain conformations. stabiliza-tion of the decadeoxyoligonucleotide d(cgtacgtacg) by [co-(nh3)6]3 binding to the guanine.
The space group P65 and unit cell constants a = b = 17.93A and c = 43.41A are used to describe the crystallization of the complex between cobalt hexammine and decadeoxyoligomer d(CGTACGTACG).
The helical axis of the molecules is parallel to the crystal c-axis. The decamers form a nearly continuous helix when they stack on top of one another. The architecture is disorganized. A dimer (pPyr-pPur)2 with each base pair being a C-G 60% of the time and a T-A 40% of the time is the asymmetric unit. An R-factor of 25.5% was obtained for 506 observed reflections above the two-sigma threshold using restrained least-squares refining. One strand of the structure was discovered to be in the ZI-conformation, while the other was in the ZII-conformation. Two symmetrically connected ZII-chains of molecules are bound by the cobalt hexammine.An "external" binding mode is created on one ZII chain when two ammonia molecules of the cobalt hexammine bind to the N7 nitrogen and 06 oxygen atoms of the guanine bases while a third ammonia molecule binds to the phosphate anionic oxygen atom of the preceding pyrimidine base. One cobalt hexammine ammonia molecule attaches exclusively to the anionic oxygens of the phosphate group of the guanine bases on the opposite ZII chain, resulting in a "internal" binding mode. Therefore, [Co(NH3)6]3 ability +'s to bind to exclusively guanine nucleotides is the basis for its ability to stabilize Z-DNA.It is hypothesized that the length of the oligomer affects the statistical disordering of deoxyoligonucleotide complexes that adopt a Z shape. In other words, tetramers and hexamers produce well-ordered structures but octamers and decamers, which are unable to use an integral number of molecules for a 12 base pair repeat, do not.To learn more about chain backbone visit:

Using the nerve signals to the hamstring and quadriceps in this reflex as an example, propose a model for regulation of smooth muscle activity in the esophagus during the swallowing reflex (see Figure 41.10).
As you swallow, the esophageal muscles simultaneously contract and relax, creating peristalsis. One explanation for this alternation is that each portion of muscle gets nerve signals that alternate between excitement and inhibition.
What is peristalsis?Food is moved through the digestive system by a sequence of wave-like muscular contractions called peristalsis. The process starts in the esophagus, where powerful waves of smooth muscle transport balls of ingested food to the stomach. The meal is then broken down into a liquid substance called chyme there, where peristalsis proceeds.
It may be simpler to notice the wave-like action if you stretch out a segment of the intestine. The chyme is mixed and shifted back and forth by the action. As a result, nutrients can be absorbed by the bloodstream through the small intestine's walls.
Peristalsis in the large intestine aids in the absorption of water from the indigestible fiber into the bloodstream. The leftover waste is then expelled through the rectum and anus.
Therefore, peristalsis helps in swallowing in the esophageal muscles.
