Mutualism- Two organisms benefit from each other Ex: whale shark getting cleaned by remora fish which get a meal.

The elements hydrogen and carbon are two major components from the listed elements making up at least 3% each of the human body.

The human body is composed of six elements, including oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus, which account for around 99% of its mass. The remaining five elements, potassium, sulphur, sodium, chlorine, and magnesium, account for only about 0.85% of the total makeup. All 11 of them are required by life. The remaining elements are trace elements, of which more than a dozen are thought to be essential for life based on convincing evidence. The body mass of magnesium, the least abundant of the 11 non-trace elements, is not equal to the combined mass of the trace elements (less than 10 grammes for a human body).

Hence, The elements hydrogen and carbon are two major components from the listed elements making up at least 3% each of the human body.

A sister chromatid is a DNA molecule that is made up of two identical copies of the same chromosome. Chromosomes are the genetic material found in the nucleus of the cell, and sister chromatids are formed when the chromosomes replicate during cell division.

Sister chromatids are identical copies of the same chromosome, which are held together by a specialized protein structure known as a centromere. The centromere is responsible for the proper segregation of the sister chromatids during cell division. The sister chromatids are made up of two strands of DNA, which are connected to each other by a protein called a histone. Each strand is held together by hydrogen bonds, which are formed between the base pairs of the DNA.

The CT max of the population will increase over many generations due to natural selection. CT max stands for critical thermal maximum.

It is the upper thermal limit beyond which aquatic species are unable to tolerate and become distressed. CT max is an important physiological parameter that shows an animal's capacity to deal with thermal stress, such as temperature extremes. If the population produces an enzyme that enables them to tolerate high temperatures, then it is reasonable to conclude that they would have a better thermal limit, and their CT max would increase. The offspring from the mating of a few infected individuals, which expressed the modified enzyme production, would not have the same enzymes. However, natural selection would play a vital role in increasing the CT max of the population over many generations. Natural selection is the process by which nature selects the organisms that are better suited to survive in a specific environment. Organisms that possess traits that enable them to survive in a given environment are more likely to reproduce and pass those traits to their offspring. As a result, the overall population will shift toward those traits over time. Therefore, over many generations, natural selection will favor those individuals that produce the modified enzyme, and the population's CT max will increase.

Answer: Hemostasis includes three steps that occur in a rapid sequence:

Explanation: 1) vascular spasm, or vasoconstriction, a brief and intense contraction of blood vessels; (2) formation of a platelet plug; and (3) blood clotting or coagulation, which reinforces the platelet plug with fibrin mesh that acts as a glue to hold the clot.

Human DNA polymerase cannot be used in polymerase chain reaction because it disables at a high temperature.

Polymerase chain reaction (PCR) is a biological technique in molecular biology used for creating multiple copies of DNA from a sample.

The principle behind PCR involves the use of high temperature. An enzyme called polymerase is used to catalyze the formation of polymers of DNA using an existing strand of DNA as a template.

However, TAQ polymerase is used because it tends to be stable at high temperatures unlike human DNA polymerase that disables when it reaches a high temperature.

CAST FOSSILS.

Explanation: To understand what a cast fossil really is,let's look at what a fossil is generally.

Fossils are traces of what are formed and left of living things which dates back to a long time ago. Fossils are often found in sedimentary rocks examples; Shales, limestone and sandstone.Fossils are left over animals/plants.

Not all fossils are remains of living things.

There are different types of fossils; FROZEN FOSSILS; When an animal is trapped and freezed as a result of drop in temperature.

IMPRINT FOSSILS; They are prints made and left when animals walk or move over clays,these imprints dries and get covered by other sediments.plants also leave imprint fossils.

AMBER FOSSILS; These are fossils that are formed when tiny insects and bugs become trapped in saps of trees, when these saps dries up,they become hard and and an Amber is formed.(a seminiferous material).

CAST FOSSILS; These are fossils that form as a result of the death of plant,animal or any organism,when this happens,chemical reaction occurs which brings about a degradation in the bones and flesh if the organism,cavities are formed and minerals are deposited in those cavities bringing about a cast which looks like the original form or image of the organism.

Housing rats in a complex social environment with much stimulation leads to some changes in brain structure, including b) all of the given answers.

Housing rats in a complex social environment with much stimulation can result in various changes in brain structure. These changes include increased cortical mass, increased dendritic branching of cortical neurons, and prolonged neural health, well into senescence. The complex social environment provides opportunities for social interactions, cognitive stimulation, and physical activity, which can lead to enhanced brain development and plasticity. Increased cortical mass suggests structural adaptations in the brain, potentially indicating improved cognitive abilities. The increased dendritic branching of cortical neurons signifies increased synaptic connections and neural complexity, which can enhance information processing and learning. Prolonged neural health into senescence suggests that the enriched environment may have a protective effect against age-related cognitive decline. Overall, a complex social environment with stimulation has a positive impact on brain structure in rats.

The distance from Penn State to the epicenter of the earthquake is approximately 350 kilometers.

To determine the distance between Penn State and the epicenter of the earthquake, we can use the time lag between the P and S waves, which is related to the distance from the epicenter through a mathematical formula that depends on the speed of seismic waves in the Earth's interior.

The lag time between the P and S waves is 140 seconds, which means that the seismic waves traveled from the epicenter to Penn State in 140 seconds.

The speed of seismic waves in the Earth's interior depends on the type of rock they pass through. On average, the speed of P waves is about 6 kilometers per second, while the speed of S waves is about 3.5 kilometers per second.

Using the formula:

distance = speed x time

we can calculate the distance from Penn State to the epicenter as:

distance = (6 km/s - 3.5 km/s) x 140 s

distance = 2.5 km/s x 140 s

distance = 350 km
