Which of the following processes describes a chemical change?

Answer:

Amontons’s law. If the temperature is increased, the average speed and kinetic energy of the gas molecules increase. If the volume is held constant, the increased speed of the gas molecules results in more frequent and more forceful collisions with the walls of the container, therefore increasing the pressure

B Because Cellulose is a polysaccharide consisting of linear chain of numerous linked D-glucose units whereas proteins are formed of number of amino acids linked together by peptide linkage.

Cellulose is a polysaccharide and a structural component of the plant cell. It is a carbohydrate made of many monomers linked together. Thus, B is the correct option.

Cellulose is an organic chemical that is insoluble in water and is a tough structure classified as carbohydrates. Cellulose is a structural component of plant cells.

It is made by monomer units linked by the beta-1,4 glycosidic bonds and is a biodegradable, tasteless organic compound with the chemical formula (C₆H₁₀O₅)ₙ.

It is the main component of the plant cell wall that provides support and shape due to its fibrous structure. It is made of linear chains of D-glucose units that makes the polysaccharide.

Therefore, option B. cellulose is a carbohydrate.

If a person possesses the genotype Bb, either the B or the b alleles can be passed on to their progeny. So, the correct option is C.

An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual carries inside a specific gene or genetic region are also referred to as the genotype.

The term "genotype" relates to an organism's whole gene pool, or, in other words, the genetic make-up of that creature. The phrase can also be used to describe to the alleles, or different forms of a gene, that an organism carries in a more specific meaning. Symbols can be used to symbolise it. For illustration, BB, Bb, and bb could be used to denote a certain gene variant.

If a person has the genotype Bb, as in the example above, then either the B or the b alleles can indeed be passed on to their progeny.

Therefore, the correct option is C.

Commensalism, in biology, a relationship between individuals of two species in which one species obtains food or other benefits from the other without either harming or benefiting the latter.

Answer:

Heart cells express different genes than skin cells

Explanation:

Cells contain instructions for their gene expression within stretches of DNA called genes, which is expressed and translated into protein.

Somatic cells are cells which contain the organism's chromosome number. They contain the entire karotype- and divide/ replicate through mitosis. In several stages of mitosis, DNA becomes condensed, is unwound and replicated, then packaged into two identical daughter cells.

All somatic cells start out undifferentiated (as stem cells). AFter the process of differentiation, they undergo changes in gene expression to become specific cell types, through processes like methylation and  gain maturity.

Mercury is used in thermometers to estimate temperatures. Liquid mercury composed of Hg atoms is a pure substance that consists of single elements. Thus, option B is correct.

Pure substances are chemicals that are matter and have been known to have distinct chemical properties because of their constant and definite composition. The physical methods of separation can not be used to separate the pure substances.

The liquid mercury is a pure substance as it has been composed of only one type of elemental atom Hg. All of its composition has been carrying the Hg atoms uniformly that possess and exhibit the same chemical and physical characteristics.

Therefore, option B. the liquid mercury is a pure substance as it is made of the same type of element.

[tex]\boxed {\boxed {\sf Enzymes}}[/tex]

Explanation:

Meat is a good source of protein because it is the main component. Hormones, oil, and water won't really produce a substance when added to meat.  Enzymes break down different substances. The right enzyme can break down proteins. The monomer, or building block, of protein is an amino acid. Therefore, when a protein is broken down, amino acids are produces.

So, from the information above, we can assume that the substance is an enzyme. Enzymes break down meat/protein into amino acids.

Answer:

A. red blood cells containing malaria

Explanation:

Malaria is a disease-causing pathogen in humans. It is caused by species of the parasite Plasmodium sp., which is transmitted as sporozoites by the Anopheles mosquito upon biting the host. These travel through the bloodstream to the liver where they mature into merozoites. These reenter the bloodstream and mature into trophozoites and schizonts that produce more merozoites.

When they multiply within the red blood cell, they burst the red blood cell open, and go on to infect other cells. This infection's symptoms are cyclic and include high fever, chills and other flu-like symptoms.

Malaria is a deadly illness, causing harm to its hosts, and in many cases death. Thus, this cannot be defined as symbiosis, which is typically beneficial to both organisms.

Answer: Environment, skin coating, and perhaps seasonal migration.

Explanation: The hadrosaur has become an unmistakable species due to its unusual bill, and bipedal legs. However this new fossil could change many studies. First off, environmental hazards. Due to the amount of carnivorous fossils found in the Dakota area, finding a nearly intact fossil of any sort should be quite impossible. This brings paleontologists to believe hadrosaurs may have had some sort of defense against predators, which brings us to skin coating. To be found in such an arctic area must have meant it would be difficult for anything herbivorous to live in the area, unless feathers, or fur was involved. This could change every theory about the so called scaly beasts we refer to as dinosaurs. This brings us to our final topic, migration. Every winter if you were to go outside, it would be highly unlikely to hear birds. This is known as migration, a period when certain animals of multiple species, typically birds, move to warmer areas for the winter. Consider if the birds descending from dinosaurs theory was correct. This could in fact be how birds somehow get this preconceived notion to migrate. This, just as wild dogs are naturally aggressive, could be instinct.

A. Multiple organ systems working together

Explanation:

All of the organ systems work together to maintain homeostasis in humans because each system does something different. For example, the circulatory system delivers oxygen rich blood to the bones and the bones create new blood cells. When one thing is wrong with one system, it affects all of the systems, like a disease. Another example of this would be the central nervous systems and endocrine working together to coordinate messages to the brain about the body's state while resting and exercising to maintain homeostasis.

High air pressure usually means clear weather because stable air is sinking. The correct option would be D.

High air pressure usually causes the sky to be clear.

This is because high air pressure causes the air at the lower atmospheric level to sink down towards the earth.

This is unlike low air pressure. It brings a cloudy sky along with precipitation.
