When your diet becomes less dependent on milk and dairy products, your lactase production declines, which leads to the development of primary lactase deficiency. The symptoms may not be apparent until maturity, but this typically occurs after the age of 2, when breastfeeding or bottlefeeding has ended.
What is Lactose Maldigestion ?
The primary milk sugar, lactose, is frequently partially maldigested due to gastrointestinal disorders or aging-related physiological changes in intestinal lactase activity. Clinical signs of "lactose intolerance" can result from lactose maldigestion. One of the most well-known benefits of probiotics, particularly lactic acid bacteria, is an improvement in lactose digestion and tolerance. This chapter examines the fundamental principles of lactose digestion and tolerance, as well as the mechanisms at play when lactase-deficient people tolerate and digest fermented dairy products well.
Incomplete digestion of lactose in the small intestine that results in some lactose reaching the large intestine/colon is known as lactose maldigestion. Maldigestion results from a higher substrate concentration (lactose) compared to the mammalian lactase enzyme's activity (lactase). Under controlled circumstances where lactose is taken alone or with milk, there is a reasonably linear relationship between food consumption and maldigestion. The majority of the scientific evidence is in favour of the hypothesis that in healthy individuals, heredity essentially controls lactase enzyme activity. Significant data also supports the idea that lactase activity declines between the ages of 3 and 5 years in 75% of the world's population, from infantile levels to adult levels (a 10–20 fold reduction).

A roller coaster car travels up and down the hills of its track. Neglecting friction, the sum of its kinetic and potential energy.
A roller coaster car travels up and down the hills of its track. Neglecting friction, the sum of its kinetic and potential energy must always remain constant.
A solid thing cannot move over another solid object without encountering friction. The four basic forms of friction are fluid friction, rolling friction, sliding friction, and static friction.
Potential energy is energy that is preserved or stored in a material or an item. The item or substance's position, organization, or condition determines the amount of stored energy. Consider it as energy with the "potential" to accomplish work.
Though a thing requires a force to store potential energy, potential energy is technically held inside matter. While the energy is kept in reserve by the object's mass, the potential energy cannot be released without the assistance of another force (either gravitational or elastic).

FILL THE BLANK. 13. If we mentally align the continents to fit Wegener's concept of Pangaea, evidence of Late Paleozoic glacial deposits ________.
If we mentally align the continents to fit Wegener's concept of Pangaea, evidence of Late Paleozoic glacial deposits is much easier to understand than in the current continental configuration.
Explain continental drift theory.
One of the earliest theories among geologists regarding how continents moved over time is known as continental drift. The revolutionary theory of continental drift was supported by fossils of similar organisms found on widely separated continents.
Most people think of the scientist Alfred Wegener when they think of the continental drift theory. Wegener presented his theory that the continents were "drifting" across the planet, occasionally crashing through oceans and into one another, in a study that was published in the early 20th century. This movement was dubbed "continental drift" by him.
Wegener was of the opinion that Pangaea, a vast, unified landmass, formerly included all of the continents of Earth. When describing Pangaea and continental drift, Wegener—an astronomer by training—used geology, biology, and botany. For instance, the extinct reptile Mesosaurus fossils are only discovered in southern Africa and South America. The Atlantic Ocean was too large for the freshwater reptile Mesosaurus, which measured barely one meter long. Mesosaurus's existence suggests a single environment with numerous lakes and rivers.

cam plants keep stomates closed in the daytime, thus reducing loss of water, they can do this because they
Crassulacean acid metabolism (CAM) plants keep stomata closed in the daytime to minimize photorespiration during photosynthesis.
Some plants are able to adapt in dry environment, such as cacti and pineapples. These plants use Crassulacean acid metabolism (CAM) to minimize photorespiration. This process is different with C3 and C4 plant.
Photorespiration is a pathway that competes with the Calvin cycle. It occurs as the rubisco acts on oxygen rather than carbon dioxide. Photorespiration causes sugar synthesis is decrease.
To prevent photorespiration, CAM plants open their stomata at night, allowing carbon dioxide to diffuse into the leaves. This carbon dioxide then converted to organic acid (malate). This organic acid will be stored until the next day. In daylight, CAM plants don’t open their stomata because the organic acid are go out of the vacuole and broken down for releasing carbon dioxide and enter Calvin cycle. It maintains a high concentration of carbon dioxide.

Explain why light and sound travel better in different mediums.
Light and sound will go through various types of materials at varying speeds as solids, liquids, & gases have highly varied densities.
How to explain this behaviour of light and sound?Light and sound waves behave quite differently from one another. To travel, sound waves need a medium, which is a physical substance. Physical substance is compressed and rarefied (decompressed) to create sound waves. Sound waves can pass through solids, liquids, & gases thanks to the compression and decompression processes.
Behaviour of sound- When a substance is exceptionally thick, its molecules and atoms are packed very closely together, which allows sound to move very quickly. Sound moves significantly more slowly in low density materials like air since the atoms are more widely spaced.
Behaviour of light- When moving through air and space, light moves far more quickly than sound. In addition to air and space, visible light also can pass through other materials. Additionally, several types of glass, polymers, water, and other substances can permit the passage of visible light.

Genetic differences are brought on by genetic drift, which occurs at random in any location at any time and pushes organisms to modify the frequency of their genotypes.
By genetic variants, what do you mean?
It is possible to define genetic variants as the existence of different gene sequences in animals belonging to the same species.The genetic drift in the population size of the northern elephant is caused by hunting. Anyone's specific genotype may benefit from hunting, and when this genotype may interbreed, it results in fewer genetic differences.Genetic differences therefore result from genetic drift, which occurs at random in any location at any time and drives organisms to alter their genotype frequency.Genetic variation is the variance in DNA sequences among members of a population. Germ cells, such as sperm and eggs, as well as somatic (all other) cells, are subject to variation.Variation in genetics refers to a person who exhibits traits that are unique from those seen in others of the same sort. It could also be relevant to the genomic differences between individuals of the same species or between populations of the same species that are found in various regions of the globe. It results through chromosomal crossing-over during gametogenesis, which is a special type of genetic recombination. A mutation, particularly one that permanently alters the chromosomal structure, can also cause genetic diversity. Consequently, a variant or mutant may also be affected by genetic variation. An organism that has developed a characteristic(s) due to mutation is referred to as a mutant.Hence, Genetic differences are brought on by genetic drift, which occurs at random in any location at any time and pushes organisms to modify the frequency of their genotypes.
