The temperature of a substance changes from 120 C to 35 C. Which of the following is true?
The Kinetic Energy of the particles did not change.
The particles of the substance resulted in a high Kinetic Energy.
The particles of the substance initially had high Kinetic Energy.
The particles of the substance initially had high Kinetic Energy.
Does the kinetic energy of a particle change as the temperature changes?Gas particles move quickly in all directions and regularly collide with one another and the container's side. The particles gather kinetic energy and accelerate as the temperature rises. The particles' real average speed is influenced by their mass and temperature.
In liquids, particles are quite close together and move with random motion throughout the container. Due to the closer proximity of the particles, collisions between them happen more frequently than in gases even if particles are moving quickly in all directions.

c. A young man learns that he is infertile because his sperm are nonmotile.
d. A young child dies because her cells lack an enzyme that normally breaks down a membrane glycolipid that therefore accumulated in the membranes of her nervous system.
e. A young child is placed on a milk-free diet because the mucosal cells that line his small intestine do not secrete the enzyme necessary to hydrolyze lactose, the disaccharide present in milk.
Answer:
a. mitochondria, underactive
b. peroxisome, underactive
c. flagella, underactive
d. lysosome, underactive
e. Endoplasmic reticulum/Golgi apparatus/transport vesicles, underactive
Explanation:
Cyanide is a toxic compound that inhibits the Cytochrome c Oxidase I (COI) in mitochondria, which is an enzyme known to catalyze the final step in the mitochondrial electron transfer chain. Adrenoleukodystrophy is an X-linked genetic disease caused by a mutation in the ABCD1 gene (ATP-binding cassette, subfamily D, member 1). ABCD1 encodes the adrenoleukodystrophy protein (ALDP), which is involved in the transport of long-chain fatty acids into peroxisomes. Flagella are cellular structures composed of proteins (microtubules) specialized to carry the male's DNA to the egg cell, i.e., they are responsible for sperm motility. Lysosomal storage disorders (LSDs) represent a group of inherited diseases caused by mutations capable of altering lysosome functions. LSDs are especially associated with defective (abnormal) lysosomal enzymes that are unable to degrade macromolecules such as, in this case, a membrane glycolipid. Finally, lactase is an enzyme produced in small intestine cells. Within these cells, the signal sequence of the preprolactase precursor is cleaved in the endoplasmic reticulum (ER). Subsequently, the protein precursor travels to the Golgi complex for processing (i.e., glycosylation), thereby a mature enzyme (lactase) is generated.

Throughout the day, activities in the liver, kidneys, and endocrine glands undergo large changes. Body temperature, blood pressure, and amino acid levels also shift from hour to hour. In fact, people tend to be more energetic and alert when these and other activities are at their highest point once a day. This is a description of Group of answer choices
Answer:
Circadian rhythms.
Explanation:
Stimulus in biology can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). All living organisms (both plants and animals) respond to changes in their environment and as such an appropriate reaction or response is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ.
Since both plants and animals respond to environmental stimuli, it simply means that, these living organisms have physiological cycles referred to as circadian rhythms.
Circadian rhythms is a natural internal process that controls the physical, mental, and behavioral changes in living organisms such as the sleep-wake cycle. The circadian rhythm is simply the internal body "24 hour" clock.
For example, there are large changes in the activities that happens with respect to the organs such as kidney, liver and endocrine glands within the body of living organisms throughout the day. Also, they experience timely shift in blood pressure, amino acid levels, body temperature, metabolism, etc.
Hence, living organisms are usually more energetic and at alert when the aforementioned activities and others are at their highest point once a day as a result of circadian rhythms.

Residual parent material refers to the *weathered rock* and *soil* that remains in its place of origin, while *transported parent material* is material that has been carried and deposited by natural agents such as water, wind, or glaciers.
The impact of these different types of parent material on *soil formation* can be significant. Residual parent material tends to contribute to the formation of soils with characteristics similar to the parent rock. The weathering process breaks down the rock into smaller particles, allowing for the development of soil horizons and the release of minerals that influence soil fertility. In contrast, transported parent material can introduce a diverse range of materials to a given area, leading to variations in soil composition, texture, and fertility. The transportation process can mix different types of sediment, resulting in the formation of heterogeneous soils with varying properties.
Residual parent material is the rock and soil that is still located in its original location and is weathered. Transported parent material is material that is carried and deposited by natural agents such as water, wind, or glaciers. The effect of these different types of parent material on soil formation can be significant.
Residual parent material usually contributes to the development of soils with qualities similar to the parent rock. The breakdown of rock into smaller particles through weathering enables the formation of soil horizons and the release of minerals that influence soil fertility.
The physical and chemical characteristics of soils derived from this form of parent material are often similar and homogeneous, allowing for predictable fertility and properties. Transported parent material, on the other hand, can introduce a diverse range of materials to a given area, resulting in variations in soil composition, texture, and fertility.
The transportation process can blend different types of sediment, resulting in the formation of heterogeneous soils with different characteristics. Transported parent material can also be exposed to weathering processes, altering its original composition and resulting in soils with varying degrees of fertility.
While transported parent material can increase the diversity of soil properties in an area, it can also make it difficult to predict soil characteristics, particularly in areas where different types of sediment have been deposited. The relationship between parent material and soil development is complex, with both the initial characteristics of the material and the surrounding environment influencing soil properties.
In general, residual parent material contributes to the development of homogeneous soils with predictable properties, while transported parent material can result in more diverse and heterogeneous soils.

Discuss the importance of data when observing something like the outbreak of cholera or even the outbreak of COVID-19, when using the scientific method.
Data is crucial when observing outbreaks of diseases like cholera and COVID-19 because it helps identify patterns and trends in the spread of the disease. In order to understand the epidemiology of a disease, scientists need to collect and analyze data on factors such as the number of cases, the location of cases, etc.
During the cholera outbreak in London in 1854, physician John Snow collected data on the location of cholera cases and the source of their drinking water. By mapping the cases and the water sources, Snow was able to identify a contaminated water pump as the source of the outbreak. His data-driven approach helped to establish the link between contaminated water and the spread of cholera and led to improved sanitation practices that reduced the incidence of the disease. Similarly, during the COVID-19 pandemic, data on the number of cases, hospitalizations, and deaths has been critical in tracking the spread of the disease and informing public health responses.
