Based on the options provided, glucose (c) and K+ (a) can diffuse across the dialysis tubing, while starch (b) cannot.

Glucose is a small molecule that can pass through the pores of the dialysis tubing, allowing it to diffuse across the membrane.

K+ is a small ion that is also able to diffuse through the membrane. On the other hand, starch is a large molecule that is unable to pass through the pores of the dialysis tubing and therefore cannot diffuse across the membrane.

The ability of molecules to diffuse across a membrane depends on factors such as size, charge, and the permeability of the membrane.

Synthetic progesterone in birth control pills provides a reliable method of contraception by suppressing ovulation and inhibiting the development of follicles, thereby preventing fertilization and pregnancy.

Birth control pills containing synthetic progesterone, also known as progestins, primarily affect the hormones involved in the menstrual cycle, namely follicle-stimulating hormone (FSH) and luteinizing hormone (LH). These hormones are released by the pituitary gland and play a crucial role in the maturation and release of eggs from the ovaries.

Synthetic progesterone works by inhibiting the secretion of gonadotropin-releasing hormone (GnRH) from the hypothalamus, which, in turn, reduces the release of FSH and LH from the pituitary gland. This negative feedback loop results in the suppression of ovulation and the development of follicles in the ovaries.

Without sufficient levels of FSH and LH, the follicles in the ovaries cannot develop fully, preventing ovulation. Additionally, synthetic progesterone thickens the cervical mucus, making it more difficult for sperm to reach the egg even if ovulation were to occur.

Explanation:

Co-factors are molecules that are required for enzymes to function properly. Enzymes are biological molecules that catalyze chemical reactions in living organisms, and they work by binding to a specific substrate and then converting it into a product.

Co-factors are often small molecules, such as vitamins, minerals, or other organic compounds, that are required for the enzyme to bind to the substrate and to catalyze the reaction. Co-factors are important because they help to activate the enzyme and make the reaction more efficient. Without the co-factor, the enzyme would not be able to bind to the substrate and the reaction would not occur. Co-factors are also often required in small quantities, and their presence is often limited by the availability of the substrate.

After the enzyme reaction is completed, the co-factor is typically not restored by the enzyme. Instead, the co-factor is usually degraded or removed from the reaction. This is because the co-factor is not needed for the enzyme to continue to function, and its presence could interfere with the next reaction.

True. In at least one group of fish, called osteichthyes, the swim bladder has been modified to become a primitive lung.

This adaptation allows these fish to breathe air when oxygen levels are low in the water. The swim bladder, which is typically used for buoyancy control, has evolved in these fish to take in oxygen directly from the air. This adaptation is believed to have occurred as a response to environments with low oxygen levels, such as stagnant or oxygen-depleted waters. The ability to breathe air provides an advantage to these fish, allowing them to survive in challenging conditions.

Gene regulation typically occurs at the transcription stage, when the genetic information encoded in the DNA is copied into a messenger RNA (mRNA) molecule.

During transcription, a complex set of regulatory proteins and RNA molecules work together to control whether a particular gene is turned on or off, and to what extent. This regulatory system allows cells to respond to changing environmental conditions or developmental cues, by selectively expressing or repressing specific genes.

Once the mRNA is produced, it can be further modified or degraded to control its stability and translation into a protein, but most of the critical gene regulation occurs during transcription.

Explanation:

Ecological succession is the process of change in the species structure of an ecological community over time. The time scale can be decades (for example, after a wildfire), or even millions of years after a mass extinction.[1]

Succession after disturbance: a boreal forest one year (left) and two years (right) after a wildfire.

The community begins with relatively few pioneering plants and animals and develops through increasing complexity until it becomes stable or self-perpetuating as a climax community. The "engine" of succession, the cause of ecosystem change, is the impact of established organisms upon their own environments. A consequence of living is the sometimes subtle and sometimes overt alteration of one's own environment.[2]

It is a phenomenon or process by which an ecological community undergoes more or less orderly and predictable changes following a disturbance or the initial colonization of a new habitat. Succession may be initiated either by formation of new, unoccupied habitat, such as from a lava flow or a severe landslide, or by some form of disturbance of a community, such as from a fire, severe windthrow, or logging. Succession that begins in new habitats, uninfluenced by pre-existing communities is called primary succession, whereas succession that follows disruption of a pre-existing community is called secondary succession.

Succession was among the first theories advanced in ecology. Ecological succession was first documented in the Indiana Dunes of Northwest Indiana and remains at the core of much ecological science.[3]

The oceanic lithosphere subduct under continental lithosphere, whereas continental lithosphere does not subduct under oceanic lithospere because the oceanic lithosphere is denser than the continental lithosphere.

This refers to the rigid and rocky layer of the Earth and consists of the crust and the solid outermost layer of the upper mantle while density is defined as the mass per unit volume of a substance.

The oceanic lithosphere is made up of mafic crust and ultramafic mantle while the continental lithosphere is made up of heavy mantle peridotite and the former gets shoved down underneath the overriding plate which is because it contains denser rocks than the latter.
