Answer:

The correct answer is the second statement that it will swell.

Explanation:

The majority of the sugary candies get dissolve when kept in water. However, the gummy bears get larger instead of getting dissolved in the water due to the presence of gelatin in it. When the gummy bears are kept in water, the molecules of water, that is, the solvent get within the bear by the process of osmosis.  

The molecules of water cross the semipermeable membrane and move into the region of higher solute region in order to equalize the concentration of solvent on both the sides of the candy surface.  

In the beginning, less water and more gelatin are present within the gummy bear. However, to make things equal, the molecules of water are moved within the candy where there are lesser water molecules and larger molecules of gelatin present. This gelatin presence makes the gummy bear function like a sponge by absorbing water rather than getting dissolved in it.  

Answer:

The answer is A : a water molecule at each bonding site.

Explanation:

Formation of polysaccharide is a condensation reaction i.e a molecule of water in produced every time two glucose molecule link together. Similarly formation of peptide bond between amino acids is also a condensation reaction. In fact because polysaccharide formation involves loss of several water molecules its easy to store condensed bulk like glycogen in animals and starch in plants compared to several monosaccharide glucose units.

The cell cycle or cell-division cycle is the series of events that take place in a cell leading to its division and duplication of its DNA (DNA replication) to produce two daughter cells. In bacteria, which lack a cell nucleus, the cell cycle is divided into the B, C, and D periods. The B period extends from the end of cell division to the beginning of DNA replication.

Answer:

True

Explanation:

The blood defends the body by using white blood cells to destroy pathogens, circulating antibodies to neutralize toxins, and coagulating to prevent blood loss and pathogen entry.

One of the specific functions of blood includes the defense of the body against infections and other foreign invaders. This is accomplished predominantly by the white blood cells (WBCs), which are part of the formed elements in the blood. These cells identify, attack, and destroy harmful bacteria, viruses, and other pathogens. The blood also contains antibodies and other proteins within the plasma that help neutralize toxins and mark pathogens for destruction. Additionally, the process of blood coagulation prevents excessive blood loss from the body when injuries occur, while also acting as a barrier to prevent the entry of pathogens.

Taste aversion combines learned and inherited elements, typically after a single negative experience with a food that coincides with illness. Research by Garcia and Koelling highlights its evolutionary benefits for survival. Understanding these mechanisms aids in managing treatment-related food aversions in patients.

Glucose aversion, more commonly referred to as taste aversion, is an intriguing physiological response that combines both learned and inherited elements. It is a type of conditioning in which an interval of several hours may pass between the ingestion of a substance and a subsequent negative reaction, such as nausea or illness. Individuals can develop a strong aversion to a particular taste after just one encounter with a food that coincides with illness, even if the illness is not caused by the food itself.

Research in this area, most notably by Garcia and Koelling, has shown that this can be a result of an evolutionary adaptation designed to help organisms quickly avoid harmful foods, contributing to species survival through natural selection. This form of learning is powerful because it can help organisms avoid stimuli posing real dangers, even if the association between the consumed food and the negative stimulus has a long time lapse. Human behavior, however, also showcases the cultural and environmental influences on food preferences and aversions beyond just innate mechanisms.

Understanding the mechanisms behind taste aversion can be beneficial in helping individuals, such as cancer patients, manage treatment-induced nausea. The association between taste and illness in these cases can complicate the intake of nutritious foods necessary for recovery. Consequently, figuring out ways to dissociate these cues could improve patient care and outcomes.

According to this species-area curve for reptiles and amphibians on a West Indian archipelago, a 50% decrease in area will change the number of species living in the remaining area by -10%.  A graph depicting the relationship between the size of a region and the biodiversity that it can support is called a Species-area curve.

Cervical plexus is the major branch of phrenic nerve, going through the thorax to give innervation of the diaphragm. Nerve impulses from the inspiratory centre in the brain travel down it, causing contraction of the diaphragm, so that inhalation can occur.

The phrenic nerve is a branch from the cervical plexus and it innervates the diaphragm, playing a vital role in the process of breathing. This nerve is connected to the spinal cord at cervical levels 3 to 5.

The phrenic nerve is a branch from the cervical plexus. It emerges from the spinal cord at cervical levels 3 to 5. This nerve plays a crucial role as it innervates the diaphragm, the muscle responsible for the process of ventilation. The phrenic nerve carries motor fibers that control the contractions of the diaphragm, facilitating breathing. It's worth noting that spinal cord damage below the mid-cervical level may not be fatal owing to the fact that these fibers have already left the spinal cord to enter the phrenic nerve.

There's more to this, though. The cervical plexus, which gives rise to the phrenic nerve, is composed of axons from spinal nerves C1 through C5. This comes together to form the phrenic nerve which connects to the diaphragm at the base of the thoracic cavity.

Understanding the role and origin of the phrenic nerve is vital as it highlights the interconnected nature of our nervous system and the importance of each nerve in maintaining overall body function.

As the area of a habitat increases, the number of species within that community also increases due to factors like resource availability and diverse microhabitats. This species-area relationship is critical for understanding biodiversity and its conservation.

Studies in ecology have shown a consistent trend indicating that as the area of a habitat increases, so does the number of species present within that community. This concept is captured by the species-area relationship, which is often depicted as a curve that demonstrates that larger areas tend to sustain more species. This can be due to a variety of factors such as greater availability of resources, more diverse microhabitats, and reduced risk of extinction due to a larger population size.

The diversity of a community refers to both the number of species (species richness) and their relative abundance within a given habitat. Conversely, when habitat is lost and the area decreases, the number of species supported by that habitat also declines, as shown in species-area extinction estimates. Therefore, protecting and preserving large natural habitats is essential for maintaining biodiversity.

It is also essential to note that populations do not live in isolation and that the dynamic interactions within a community can shape its overall structure and function. This has been observed in various ecosystems, ranging from the low-diversity glaciers of Antarctica to the highly diverse tropical rainforests.

Hello!

We will answer that!

The central dogma of biology is the one that points us the way from DNA to protein. DNA, by transcription, is transformed into RNA. This RNA by translation is transformed into amino acids that then form the proteins.

In this question, where we have to find out which is the best way, we need to know what the options are.

I would like you to attach the options to help you. I hope to help you next time.
