Mindful eating includes which behavior?
feeling the textures of your food
eating while watching television
O photographing every meal that you eat
O recording every calorie that you consume
Answer:
A, "feeling the textures of your food."
Explanation:
While every option does appear mindful, only A is the correct answer. The true definition of mindful eating is that you are paying undivided attention to your food and how it makes you feel. This includes the aroma, textures, and your sensual awareness. This does not involve computing calories or partaking in obsessive behaviors. Watching television while you eat would be distracting you from the experience.

if a snake species were introduced to an ecosystem where it had no natural predators, what long-term effect do you predict the snakes would have on the population dynamics of the ecosystem?
They would breed with native snake species, resulting in an increase in biodiversity in the ecosystem.
They would serve as a food source for predators of native snakes, causing an increase in native snake populations.
They would form mutualistic relationships with native snakes, since they would occupy the same niche in the ecosystem.
They would compete with native snake species for resources, causing a decline in native snake populations and possibly extinction.
Answer:
D. They would compete with native snake species for resources, causing a decline in native snake populations and possibly extinction.
Explanation:
Just took the test! :D
They would compete with native snake species for resources, causing a decline in native snake populations and possibly extinction. Hence option D is correct.
What are predators?Predators are living things that go after and kill prey. Both carnivores and omnivores can be predators. Predation can be classified into four categories: carnivory, herbivory, parasitism, and mutualism. Depending on whether or not the victim dies, each sort of predation can be classified.
Predators include weasels, hawks, wolves, mountain lions, and grizzly bears. Because they are carnivores, predators only eat meat.
If a snake species were introduced to an ecosystem where it had no natural predators, it would compete with native snakes. Hence, option D is correct.

A) mesenchymal ossification B) endochondral ossification C) perichondrium ossification D) intramembranous ossification
Answer:
The correct answer is - option D. intramembranous ossification
Explanation:
Conversion of mesenchymal tissue into bone directly is known as intramembranous ossification. The bone formation is the process that involves the conversion of mesenchyme or primitive connective tissue from laying of bone directly. It is made up of granular cells and fibers in the matrix.
It is the formation of tissue of bone in a fetal without any template or cartilage base during fetal development.
Thus, the correct answer is - option D. intramembranous ossification
Describe and explain the three basic cyclic reasons why the temperature of the Earth has fluctuated over time (Milankovitch Cycles). Please make sure to use complete sentences and proper grammar.
PLEASE HELPPPPP
The three basic cyclic reasons why the temperature of the Earth has fluctuated over time are Eccentricity, Obliquity and Precession.
The Milankovitch CyclesThe Milankovitch Cycles are defined as the cyclical movement related to the Earth's orbit around the sun. These cycles cause variations in the amount of solar energy reaching the Earth.
Milankovitch Cycle was developed by the Serbian mathematician called Mulutin Milankovitch.
The climatic effects of the Milankovitch Cycles include:
Eccentricity: This is defined as the shape of Earth's orbit. This cycle is the reason why the seasons are slightly different in length.Obliquity: This is defined as the angle that Earth's axis is tilted with respect to Earth's orbital plane. The greater Earth’s axial tilt angle, the more extreme our seasons are.Precession: This is defined as the direction that Earth's spin axis is pointed. Axial precession makes seasonal contrasts more extreme in one hemisphere and less extreme in the other.Learn more about earth's temperature here:

Movement of molecules across the cell membrane depends on the concentration of the molecules on both sides of the membrane i.e the higher the concentration of molecules,the higher the attraction,since the molecules have the same concentration on both sides of the membrane the molecules does not move to either of the sides.
Raj takes a meteorology class and learns about the effects of air density on the weather. What affects the density of air? Explain.
Answer:
Temperature, pressure, and moisture/humidity are all factors to consider.
Warm air has a lower density and rises/becomes buoyant.
The air is less dense at higher elevations above sea level. To bring the same amount of oxygen into the lungs when running at high altitudes, you'll need to take more deep breaths.
Humidity is less dense at higher temperatures and pressures. The weight of water molecules is less than that of nitrogen and oxygen molecules. To get more moisture into the same volume of air, some of the heavier nitrogen and oxygen must be displaced.

What feature of double-stranded dna makes it necessary to have a leading strand and a lagging strand during replication?.
Answer:
there must be a pre-existing chain of nucleotides
Explanation:
So RNA primers are used for initiation of new DNA chains.
RNA primer is short piece of RNA, synthesised at the end of the new strand with the help of DNA specific RNA polymerase enzyme called primase and primers provide free -OH for DNA polymerase to start polymersing. leading template strand requires primer only ones. But lagging template strand requires many primers. Once primer is ready DNA Pol(III) will come & start adding deoxyribonucleotide to the -OH of primer by complementary basepairing. Two nucleotides link each other by phosphodiester bond. The daughter DNA for template is synthesised continuously, Therefore called leading strand. DNA polymeraseIII has Exonuclease activityIt can add nucleotides in the direction. Replication is discontinuous on the other template with polarity because only a short segment of DNA strand can be built in direction due to exposure of a small stretch of template at one time.

Sharks and whales are a classic example of two different animals revealing
similar traits in the same environment. One of the similarities of these two
marine animals is their habitat. They both live in the vast range of depth in
their environment. They also have the same fin structure. They only have a
single tail for propulsion and because they are both large aquatic animals,
they both consume large volume of food, however, sharks hunt for their
food. Whales do not have this hunting tendency. Another difference of
sharks to whales is their class. Whales are mammals while sharks are fish
but they both live in the ocean. Also, whales have bones while sharks only
have cartilages.
Answer: The similarities between shark and whales are indicative of convergent evolution.
Explanation:
Convergent evolution can be defined as the process in which the organisms are not closely related but they evolve similar traits as a result of living in a similar kind of environment or adapting traits which enable them to perform the same ecological niches.
The similarities between shark and whale is indicative of convergent evolution as the animals are not related to each other phylogenetically but they live in the same environment this they evolve same kind of traits.
The similarities between sharks and whales represent an example of convergent evolution.
Convergent evolution refers to the evolution of similar phenotypic traits in unrelated and/or distantly related species.Convergent evolution creates analogies, i.e., different structures that may have the same function but were not present in the last common ancestor of both species. On the other hand, divergent evolution refers to the development of dissimilar phenotypic traits in closely related species as a result of evolution by natural selection, thereby leading to speciation.In convergent evolution, similar phenotypic features (traits) have evolved independently and repeatedly in each lineage in order to adapt to particular environmental conditions.In conclusion, sharks and whales are an example of convergent evolution because they are distantly related species that exhibit similar phenotypic features in the same environment.
