The mass of particles affect the rate of diffusion; hence a decreased mass particles implies that diffusion rate will be faster.

The mass of particles of substances are important factor in the diffusion processes. Substances or particles which a smaller masses will quickly or faster when diffusion is going on. When the particles are of a bigger mass, the particles will result in a lower diffusion rate

That being said, diffusion is the movement of substances from a region of higher concentration to region of lower concentration. An example of a diffusion process is the movement of gas particles perfume from its container to a room where it is sprayed or released.

So therefore, if the mass of an object is reduced, the diffusion rate will be faster.

The element that gives the Fibrous joints the ability to resist stretching and control the amount of movement at the joint is Collagen fiber.

Fibrous joints are immovable or fixed joints, as the movement of joints is not allowed between the bones. They do not have a joint cavity. In these joints, the articulating parts are separated by collagen fibers, also known as white connective tissue, which passes from one part to another.

Collagen fibers contain a hierarchical structure made up of collagen molecules, microfibrils, fibrils, fibers, and fascicles that prevents tendon and other load-bearing tissues from deforming.

Fibrous joints are subdivided into three types namely sutures, gomphoses, and syndesmoses.

Biotic factors affect communities because they comprise animals and plants and microbes which are a necessary part of our environment whereas abiotic factors affect the ability to survival and reproduction of an organism.

Biotic factors such as the presence of autotrophs or self-nourishing organisms such as plants, and the diversity of consumers also affect an entire ecosystem. Abiotic factors affect the capacity of organisms to survive and reproduce. Abiotic limiting factors limit the growth of populations. The abundance and distribution of organisms in an ecosystem are affected by biotic factors, which involve living organisms. the appearance of new predators: in balanced ecosystems, predators and prey have developed together. the arrival of a new predator will disrupt the numbers of prey and other organisms. Biotic factors that affect communities; moisture levels: animals and plants are adapted to growing at the moisture levels available; soil pH and mineral.

The answer to the statement " The relationship between the protists that cause human malaria and humans is an example of commensalism " is false

The simple reason why commensalism does not exist between malarian parasites and humans is because, commensalism is not a biological association where an organism cause diseases or has any detrimental effect on the other other. Rather, in commensalism, on of the organisms benefit from the other, and the other commensal does not benefits or harm the other.

However, the relationship which exist between malarian parasites and humans is parasitism. This is because the protist, feed on nutrients from the the body of the host, humans and cause disease known as malaria.

So therefore, the Plasmodium species are the protists which causes malaria to humans and this association is known as parasitism.

The allele frequency of the W is 90%.

According to the definition of an allele given in the top textbooks about genetics and evolution, an allele is a different arrangement of the same nucleotides in the same location on a long DNA molecule.

"A locus is the  genomic or chromosomal site of a gene or other genetic element, and alleles are different DNA sequences at a locus.

SNPs, or single nucleotide polymorphisms, are the most basic alleles. however they can also involve base pair-sized insertions and deletions, up to thousands of them.

Typical popular definitions of "allele" only include several alleles found inside genes. For instance, the ABO gene, that has six common allele, regulates the ABO blood grouping. Nearly every live person's phenotype again for ABO gene is some mix of simply these in population genetics.

The best option that explains that why salivary amylase does not break down proteins is that proteins do not have the right substrate for the enzymes.

In the field of biology, we can describe enzymes as biological catalysts that are used to speed up a reaction. Each enzyme is specific for a reaction because the active site of an enzyme is specific for a particular reactant.

As salivary amylase is an enzyme that is specific for breaking down starch because its active site is specific for the starch reactants, hence the amylase enzyme will not work for proteins. The protein reactants will not fit into the active site of the salivary amylase enzyme.

Although a part of your question is missing, you might be referring to this question:

Uranium is used to determine a rock's age.

The uranium in rocks decays at a steady rate, producing subatomic particles and turning into lead. Scientists estimated the age of the globe at 4.6 billion years by examining the uranium-to-lead ratios in the oldest rocks on the planet. U-235 dating reveals that a rock is 2.84 billion years old.

Why, given that rocks are so old, can the age of rocks be determined using uranium-238?

The age of the rock increases with lead content. Since uranium-238 has a lengthy half-life, only the oldest rocks can be dated. Because so little of the uranium will decay, this method is unreliable for determining the age of rocks that are younger than 10 million years.

Following a heart attack, lactic acid would accumulate in the tissues due to glycolysis and fermentation, and the production of ATP would decrease. Thus, alternative A and C.

Coronary arteries are blood vessels found on the heart that supply blood rich in oxygen and nutrients to the muscles of the heart. The heart makes use of oxygen, just like any other muscle in the body to break down glucose for energy.

However, if the coronary arteries become narrowed or blocked, the supply of oxygen and other nutrients to the heart is reduced or interrupted. This could happen due to a build-up of cholesterol or plaque in the coronary artery, making it narrow or blocked and leading to a heart attack.

Due to the lack of oxygen, the cells in the heart start to break down glucose using lactic acid fermentation, a type of anaerobic respiration. Since the body cannot further break down lactic acid, it accumulates in the tissues. ATP production also decreases because lactic acid fermentation does not produce as much ATP as aerobic respiration.

Energy is transported from lower to higher trophic levels through the food chain or web. However generally only about 10% of the energy in one level is available for the next level.

Used in metabolic processes or released into the environment as heat. This loss of energy explains why there are rarely more than four trophic levels in a food chain or web. With the 10% rule, each trophy level can only give 10% of its energy to the next level. The remaining 90% is used for survival growth, and reproduction and is lost to the environment as heat.

All energy pyramids begin with the transmission of energy from the sun to the first nutrient-level producers. The first, lowest level contains green plants, which are producers.

While Non-programmed decisions will generally need to be processed via the reflective system in our brains in order for us to reach a good decision, with programmed decisions, heuristics can allow decision makers to switch to the quick, reactive system.

What are programmed and non-programmed decisions ?

Programmed decisions are those decisions that occur more frequently and are quickly executed, almost instinctly, without needing much of a thought process, by what we call the reactive system; they are repeated over time. while non-programmed decisions are those that present unusual or new situations and require a deeper reflection and understanding of the issue. Those are processed via the reflective system in the brain; they hardly re-occur and mostly spontaneous.
