Answer:

Characteristics of epithelium tissue

1.Polarity- Epithelium is arranged so there is one free surface (apical surface) and one attached surface (basal surface)

2.Cellular nature– Cells in epithelium fit closely together side by side and sometimes atop each other to form sheets of cells. These sheets are held together by specialized junctions.

3.Supported by connective tissue– Attachment to a layer of connective tissue at the basal surface forms a layer called the basement membrane, an adhesive layer formed by secretions from the epithelial cells and the connective tissue cells.

4.Avascular– Epithelium typically lacks its own blood supply.

5.Regeneration– Epithelium cells can regenerate if proper nourished.

6.Absence of nerves (except for a few axons in the deeper layers)

Classification scheme of epithelial tissue:

Typically epithelial tissue is classified on the basis of arrangement and shape of cells. For naming the tissue types, the arrangement of the cells is stated first, then the shape, and is followed by “epithelium” to complete the naming. For example; Simple Squamous Epithelium.

What does base pair rule mean?

almond37 [142]

Answer:

A base pair is two chemical bases bonded to one another forming a "rung of the DNA ladder the DNA molecule consists of two strands that wind around each other like a twisted ladder. Attached to each sugar is one of four bases--adenine (aka A), cytosine (aka C), guanine (aka G), or thymine (aka T).

A car traveling at 60 mph has how much more energy than a car going at 20 mph? K.E. increases by a factor of there is no increas

inn [45]

Answer:

Assuming that the masses of the cars are the same

9 times

Explanation:

Kinetic energy can be computed using the formula:

$KE = \dfrac{mv^{2}}{2}$

Where:

KE = Kinetic energy

m = mass

v = velocity

As you can see in your problem, the velocity of the the first car mentioned is 3 times faster.

Looking at the the formula, velocity is raised to two (2). So if we put it in terms of equations this is how it will look:

Let v = velocity of the slower car

Car 1: velocity = (3v)

$KE=\dfrac{mv^{2}}{2}$

$KE=\dfrac{(m)(3v)^{2}}{2}$

$KE=\dfrac{(m)9v^{2}}{2}$

The increase is by a factor of 9.

What is the meaning of word "true" in biology?<br> for example true breeding plants

vaieri [72.5K]

A true-breeding plant is one that, when self-fertilized, only produces offspring with the same traits. True-breeding organisms are genetically identical and have identical alleles for specified traits. It is a kind of breeding wherein the parents would produce offspring that would carry the same phenotype. Basically true means identical or same. Hope this somewhat helped :)
