Answer:
Muscle tissue has four unique characteristics, which include excitability, contractility, extensibility, and elasticity. Muscle tissue has four unique characteristics, which include excitability, contractility, extensibility, and elasticity.
Explanation:
Muscle tissue has four distinct properties: excitability, contractility, extensibility, and elasticity.
What are muscles?The human body contains approximately 600 muscles. Skeletal, smooth, and cardiac muscles are the three primary types of muscle.
The neuromuscular system is the collaboration of the brain, nerves, and skeletal muscles to end up causing mobility.
Muscle fibers are highly specialized cells that make up the muscular system. Their main function is contractility.
Movement is governed by muscles, which are attached to bones or vital organs and blood vessels. Muscle contraction causes nearly all movement in the body.
Muscle tissue is distinguished by characteristics that enable movement. Muscle cells are excitable, meaning they respond to stimuli.
They are contractile, which means they can simplify and produce a pulling force. When muscles are attached between two movable objects, such as two bones, they contract.
Thus, these are the three physiological concepts associated with muscular tissues.

What year was the first animal cloned?
Answer:the year was 1996 when an animal was first cloned
Explanation:
Geographic isolation caused a population to separate and experience two different environments. With natural selection occurring over many generations, the two populations are no longer able to successfully mate and reproduce. This is what
happens is_____.
O evolution at the species level
O sympatric speciation
O microevolution leading to speciation
O allopatric speciation
Formation of new species or speciation as a result of geographic isolation is an example of allopatric speciation.
What is speciation?Speciation is the process by which new species are formed.
There are several types of speciation;
allopathic speciation sympatric speciation peripratic speciationparapatric speciationAllopatric speciation occurs when species which are isolated from one another by physical barrier, such as a mountain range or a waterway causes new species to form as a result of inability to interbreed.
Therefore, geographic isolation which leads to speciation is an example of allopatric speciation.

Put the following in order from when they occur in the visual transduction pathway:
Optic Nerve receives signal:
Optic radiation receives signal:
Light hits photoreceptors (rods and cones):
Optic chiasm receives signal:
Ganglion cells receive signal:
Optic tract receives signal:
Bipolar cells receive signal:
Primary visual cortex receives signal:
Lateral geniculate nucleus of thalamus receives signal:
The visual pathway consists of the retina, optic nerves, optic Chaism, optic tracts, lateral geniculate bodies, optic radiations, and visual cortex.
The pathway is, effectively, part of the central nervous system because the retinae have their embryological origins in extensions of the diencephalon.
What is the pathway of vision steps?The visual pathway directs to the anatomical structures responsible for the transformation of light energy into electrical action prospects that can be analysed by the brain.
It begins at the retina and terminates at the primary visual cortex.

5. Why do you think the concrete needs to be reinforced with steel bars?
Answer:
ABA namalayan ko Yan
Explanation:
dI ko Yan alam
sorry
In concrete construction, reinforcing steel rods, bars, etc absorbs tensile, shear, and occasionally compressive stresses. Because plain concrete cannot readily endure the strain and bending stresses induced by wind, earthquakes, vibrations, and other pressures, it is unsuitable for most structural purposes. It is also responsible for holding the concrete together in the right position.

Explanation:
Would you expect to find older or newer fossils in rock layers closer to the surface? Why?
Answer:
Newer
Explanation:
Because it is like when you place a plant and its roots underground and cover it up. You have the newer dirt going over the newest roots and the roots are close to the top
(If you aren't satisfied with that explanation here's another one) :
A hundred years ago dinosaurs existed and then they died and their remains were buried under dirt. However, we know that the fossils aren't anywhere near the top. Over time fossils get buried under layers of dirt the newer ones will be near the top because they haven't had time to be more buried.
