The water particle are moving faster which cause the to expand

Warming of ocean water causes its density to decrease due to the expansion of water molecules, which increases the volume they occupy. This decrease in density plays a significant role in the stratification of ocean waters, which impacts marine ecosystems and nutrient supplies.

The decrease in density of warming water is caused by the expansion of water molecules when they absorb heat. As water warms, its molecules begin to move more vigorously, causing them to occupy more space. This increase in volume due to temperature rise leads to a decrease in density, because density is defined as mass per unit volume. Considering that the mass of water remains constant as it warms, the density must decrease as the volume increases. This phenomenon is critical to understanding oceanic processes such as thermohaline circulation and the effects of climate change on oceanic ecosystems.

When surface waters warm up, not only does the density decrease but this also affects stratification. Increased stratification can lead to reduced vertical mixing, affecting the nutrient supply essential for marine life and hence impact the entire marine ecosystem. This relationship between temperature, density, and ocean health is an important concept in environmental science and climate research.

An owl’s digestive system cannot break down parts of the prey such as teeth, bones, fur, and exoskeletons. These parts of the prey are compressed into an owl pellet. The owl regurgitates this material so that it can leave the owl’s stomach.

I Hope This Helps!!!

An owl pellet is a regurgitated mass containing the indigestible parts of an owl's prey such as bones, fur, and feathers. It is formed in the gizzard and regurgitated as a means to eliminate these materials from the owl’s body.

An owl pellet is a regurgitated mass of the indigestible parts of an owl's food. After an owl swallows its prey, the ingested food passes through their unique digestive system. It first travels through the crop where it is stored, then to the proventriculus where digestive juices break down the food, and then to the gizzard which grinds down the food with the help of swallowed stones or grit.

The owl's digestive system is unable to break down some parts of the food like bones, fur, and feathers. These are formed into a pellet within the gizzard, and then regurgitated by the owl. So, the owl pellet serves as a way for the owl to eliminate indigestible materials from its body.

The correct answer is reproductive part.

The mushroom belongs to the family of fungus. It is composed of two parts one underground part called as mycellium and the other part which can be seen above the ground. This part is the reproductive part of mushroom which is often edible. The other parts of the mushroom includes stem, hypae, volva, spores, gill, ring cap. There are variety of mushrooms available but all the forms are not eatable some of them are poisonous to human health.

A fault is a fracture through rocks that has experienced significant movement. The age of a fault is typically younger than the rock in which it is found because the fault forms after the formation of the rock. This movement can cause displacement and deformation of the rock layers, resulting in the creation of a fault.

A fault is a fracture through rocks that has experienced significant movement. The age of a fault is typically younger than the rock in which it is found because the fault forms after the formation of the rock. Faults are created when stress causes the rocks to break along a specific plane, allowing for movement to occur. This movement can cause displacement and deformation of the rock layers, resulting in the creation of a fault.

The age of a fault is younger than the rock in which it is found because the fault represents a period of tectonic activity that occurred after the rock formed and solidified.

To understand this, consider the following points:

1. Rock Formation: Rocks are formed through various geological processes such as volcanic activity, sedimentation, or metamorphism. Once a rock forms and solidifies, its age can be determined through radiometric dating methods, which give the time since the rock's minerals crystallized.

2. Fault Formation: A fault is a fracture or zone of fractures between two blocks of rock, which may have moved past each other. The movement along the fault is due to tectonic forces and can occur at any time after the rock has formed.

3. Relative Timing: The fault's formation postdates the formation of the rock. This is because the rock must first exist before it can be broken or displaced by tectonic forces. Therefore, the fault cannot be older than the rock it cuts through.

4. Geological Evidence: Field evidence such as cross-cutting relationships can be used to determine the relative ages of geological features. A fault that cuts through a rock layer must be younger than the layer it cuts.

5. Dating Techniques: While the rock can be dated using radiometric dating, the fault itself is dated by its position in the stratigraphic sequence and by dating the youngest rocks that it cuts through. The fault's activity can also be bracketed by dating the sedimentary or volcanic rocks that fill the fault zone or by dating minerals that formed within the fault due to hydrothermal activity associated with faulting.

In summary, the age of a fault is determined by the timing of tectonic activity that caused the faulting, which necessarily occurred after the rock formed. Thus, the fault is younger than the rocks it affects.

The elimination describes the discharge of waste from the body.

The food molecules that cannot be digested or absorbed need to be eliminated from the body. The removal of indigestible wastes through the anus, in the form of feces, is defecation or elimination.

Many internal organs and systems are responsible for eliminating waste from the body including: the lungs, skin, kidneys, liver, colon and lymphatic system.

The final step in digestion is the elimination of undigested food content and waste products. After food passes through the small intestine, the undigested food material enters the colon, where most of the water is reabsorbed.

Answer:

alleles

Explanation:

Allele was the term Mendel used to name these factors. He suggested that each trait is as a result of the interaction between two alleles for that trait.

Gregor Mendel, an Austrian monk is the dubbed the father of genetics for his pioneering work in the field of genetics.

He proposed the mendelian laws of independent assortment and segregation from his observation.

He suggested that each trait is carried by an allele.

When parents combines to produce an offspring, they each give a copy of their allele.

The allele gives the trait of the offspring produced.

B. alleles is the names for the trait that result of the interaction of two factors.

In genetics, an allele is one of the possible forms of a gene that exists in a population. Alleles determine the expression of traits, such as eye color or hair type, by coding for a specific variation of a particular gene.

Mendel's law of segregation suggests that each individual has two alleles for a given trait, one inherited from each parent, and that these alleles segregate during the formation of gametes (sex cells) such that each gamete only receives one allele from each parent.

Mendel's law of independent assortment further suggests that the inheritance of one trait is independent of the inheritance of another trait, meaning that the distribution of alleles for one trait does not affect the distribution of alleles for another trait.

Together, these laws suggest that each trait is the result of the interaction of two alleles, one from each parent, and that the combination of these alleles determines the expression of the trait.

The final acceleration of the skateboard will be half its initial acceleration

According to Newton's second law, the formula for calculating the force is expressed as:

F = ma .................. 1

If the mass of the skateboard doubled but the net force on it remained constant, then;

m₁ = 2m

F₁ = m₁a₁

F₁ = 2ma₁ ........................ 2

If the force on it is constant then F₁ = F and the second equation becomes;

F = 2ma₁

Divide both equations 1 and 2 to get the acceleration of the skateboard "a₁"

[tex]\frac{F}{F} = \frac{2ma_1}{ma} \\\frac{F}{F} =\frac{2a_1}{a} \\1=\frac{2a_1}{a}\\a=2a_1\\a_1=0.5a[/tex]

This shows that the final acceleration of the skateboard will be half its initial acceleration.
