Tip of the index finger contain the greater number of touch receptors.
Because the tip of the index finger has more sensory neurons than the forearm or back of the hand. There is a larger brain area devoted to receiving their signals when an area has more sensory neurons, resulting in greater sensitivity.
In comparison to the skin on the back, the fingertips have around 100 times more receptors per square centimeter. As a result, the cortical area that gets input from the fingertips is much larger than the area that receives input from skin on the back because more CNS neurons must be devoted to receiving fingertip sensations.

b) Review the results of your table and summarize your observations about
how the different substances cross membranes. (2 points)
Substances can enter and exit the cell through the membrane through passive or active transport. The processes of endocytosis and exocytosis ensure, respectively, the entry and exit of macromolecules and other particles.
In which two ways do substances cross the membrane?The selective passage of substances across the membrane occurs in two different ways:
active transport, when it involves the use of energy.passive transport, when it does not involve the use of ATP.With this information, we can conclude that substances can enter and exit the cell through the membrane through passive or active transport. The processes of endocytosis and exocytosis ensure, respectively, the entry and exit of macromolecules and other particles.

The structural adaptation an octopus would use for movement is suction cups on limbs.
What is octopus?Octopuses are highly clever creatures that have mastered camouflage and have developed a variety of cunning strategies over tens of millions of years to evade or prevent potential predators. They are able to blend in with their surroundings' colors and textures, enabling them to remain undetected.
Octopuses can quickly flee if a predator approaches by launching themselves forward by ejecting water from a muscular tube known as a siphon. Additionally, octopuses have the ability to expel a cloud of black ink that hides them and impairs an intruder's ability to smell.

What are physical properties? Give some examples.
Answer:
A physical property is any property that is measurable, whose value describes a state of a physical system. The changes in the physical properties of a system can be used to describe its changes between momentary states. Physical properties are often referred to as observables. They are not modal properties. Quantifiable physical property is called physical quantity.
Examples:
color (intensive)
density (intensive)
volume (extensive)
mass (extensive)
boiling point (intensive): the temperature at which a substance boils
melting point (intensive): the temperature at which a substance melts
Answer:
A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.

How will you do define science?Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old.
Moreover, science is a way of knowing about the world. At once a process, a product, and an institution, science enables people to both engage in the construction of new knowledge as well as use information to achieve desired ends.
Hence, science is a broad career field with many specialties and areas of study. The three main branches of science are physical science, earth science and life science, and they each have different career applications.

How do the layers of the atmosphere help to understand better the dynamics of the atmosphere and its relationship to the hydrosphere and lithosphere?
There are various layers that make up the atmosphere, and each has distinct properties and functions. Both weather generation and energy transmission take place in the troposphere, which is closest to the Earth's surface.
The stratosphere shields the Earth from damaging UV radiation along with the ozone layer. Most auroras happen in the mesosphere, where meteors burn up. Modern technology is dependent on the thermosphere, where the majority of the Earth's satellites orbit and where communication signals are sent.
The dynamics of the atmosphere and its interactions with the hydrosphere and lithosphere are better understood thanks to these layers. Foreseeing and minimising environmental problems like climate change and preserving our world, it is essential to understand the significance of each layer.

what is a structure that develops in the mesoderm and allows for more complex internal organ formation
The structure that develops in the mesoderm and allows for more complex internal organ formation is coelom.
what is coelom?
The coelom develops within the mesoderm during embryogenesis. In most animals, the coelom (or celom) is the major bodily cavity that surrounds and contains the digestive tract and other organs.
What are the functions of coelom?
Coelom acts as a shock absorber and protects against mechanical shock. It allows the body organs to move more freely and protects them from damage caused by minor bends by cushioning the internal organs.The coelomic fluid also helps in gaseous transport and transport of nutrients and waste products.Coelom provides the additional room that organs require to grow and function.

Hexabe is a hydrophobic solvent.
1) Which of the following would Hecate dissolve: A, B or C?
1. (a)What are the differences between the bonding site of a competitive inhibitor compared to an allosteric inhibitor
ANSWER: The bonding site of competitive inhibitors is at the active site on the enzyme, while the bonding site of allosteric inhibitors is NOT at the active site of the enzyme.
EXPLANATION: Competitive inhibitors compete with other substrates by binding to the specific enzyme's active site so that the other substrate cannot bind to it (the competitive inhibitor and the substrate it competes with will have similar shapes that are complementary to the active site of the enzyme).
On the other hand, allosteric inhibitors bind to an area on the enzyme that is NOT the active site. This causes the enzyme to change its shape and therefore change the shape of its active site.
what is the total charge of 2 protons, 1 neutron and 2 electrons
Answer:
helium
Explanation:
The number of protons is the atomic number, and the number of protons plus neutrons is the atomic mass. For hydrogen, the atomic mass is 1 because there is one proton and no neutrons. For helium, it is 4: two protons and two neutrons.
Hope this helps.
Helium is an element that contain 2 protons, 1 neutron and 2 electrons.
What is helium?Helium having two valence electrons and the electronic configuration 1s 2, the helium atom does not establish a chemical bond because it is a noble gas, hence its duplet is complete. Valency is therefore 0 (zero).
A noble gas or inert gas is helium. Due to having the most valence electrons that their outer shell or valence shell can support, noble or inert elements are the most stable. Because of its extremely stable structure, helium has no tendency to establish any chemical bonds.
