The tracheids, fibres, and vessels present in the xylem, become lignified during development, losing their living contents. This makes the tissue impermeable (to water) so none is lost as water is transported via the xylem. The tracheids' bordered pits allow for the rapid movement of water from cell to cell. As is with tracheids, the lignification of vessels can occur as rings, spirals, scalariform or reticulate. In the first formed xylem, rings and spirals occur more frequently. This allows for a limited amount of stretching which may occur in young structures. Both tracheids and vessels provide a pathway for the transportation of water, whilst also contributing to support.

If a function within a position spans multiple levels then?
By definition a function can not span multiple levelswhat do you mean spans well i think it mean what function with in a spans multiple can mean two levels mean if you improve you get a hight levels
What causes CHF?
Heart failure often develops after other conditions have damaged or weakened your heart. Over time, the heart can no longer keep up with the normal demands placed on it to pump blood to the rest of your body.
How do you think the earthworms setae make it well adapted to its habitat?
An earthworm's setae allow it to grab onto surfaces, which prevent it from sliding back during its odd pulsing movements. This shows it's very well-adapted to its environment, because these bristles only work at maximum potential when they support the entirety of the body, which only happens underground, where these worms live.
What is DrNumb numbing cream?
Well it's a topical anesthetic that must be applied to the skin up to 1 hour or more before the tissue is to be worked on. Here's what they won't tell you. This and any other topical anesthetic must be absorbed by the skin, this will bloat the tissue because the tissue is very much like a sponge and will absorb this chemical soup to cause the anesthetic action to occur. Now for some procedures it's fine like waxing or laser treatments, but for tattooing and body piercing the bloating effect screws up the tissue. It will not allow the tissue to accept pigments as well nor does it allow piercings to be placed correctly due to the bloating. Don't get sucked into doing anything to your skin before you talk to your tattoo artist or your professional body piercer. We have worked for years to provide you with the best training and skills available, we are good at what we do and our services are next to painless. At fifty bucks a tube it's a rip off and not worth the money for something that didn't need it in the first place.
I got my tongue pierced 5 days ago and I thought it was healing well with normal swelling and soreness but I noticed a small white bump in the front of my piercing. Is this scar tissue?
That is the tongues version of a scab and it will go away in a few days.
What are 4 ways the small intestine is well adapted to its function?
The walls of the small intestine are covered in millions of tiny finger-like ... (it's a type of tissue), this tissue is adapted to help the small intestine carry out it's function...In what ways are the small intestine adapted for their roles
What is the difference between ground tissue and vascular tissue?
The vascular tissue system comprised of the xylem and phloem function mainly for conduction of water and dissolved minerals (xylem), as well as conduction of carbohydrates, primarily sucrose, for the plant to use as food. The ground tissue system which consists of cubic or round cells with thin walls and living protoplasts, functions as aid in photosynthesis, storage, and secretion.
Difference between xylem and phloem tissue?
xylem have hard wall cell. it is a dead complex permanent tissue. it is a water conducting tissue. PHLOEM; Phloem have relatively soft wall cell. it is a live complex permanent tissue. it is a water conducting tissue.
How structure and function related?
Structure is related to its function. When the structure of something changes, so does its function. And when its function changes, the structure is bound to change too.
What are three types of tissue in vascular plant?
The three types of plant tissue are dermal, vascular, and ground.The function of dermal tissue is to cover the outer surface of the plant to protect it from physical damage as well as possible pathogens. The cuticle, a component of leaves and stems, also prevents water loss. The epidermis, another type of dermal tissue, is specialized based on the organ it is located on.Vascular tissue is made up of xylem and phloem - combined, the purpose of vascular tissue is to transport materials (water and nutrients) around the plant. As previously mentioned, xylem transport water and its dissolved nutrients through the plant whereas phloem carry organic nutrients known as photosynthate (products of photosynthesis), such as sucrose, to all the parts of the plant where such organic material is needed.Ground tissue is the tissue that is neither dermal nor vascular. Its purpose is to store materials, photosynthesize, and support the plant.
What vascular tissue carries food from the leaves to the roots?
The phloem carries the food down from the leaves. Not to be confused with xylem, which carries water up to the leaves.
Why mosses are not as well adapted to terrestrial life as ferns?
Because mosses do not have xylem and phloem as vascular system. Also the dominant plant body in mosses is gametophytic which needs more moist and shady places.
What specialized in vascular plants transport water and minerals?
Hey, so you want to know this right? Well look in your science book pg.104. And if you don't well sucks for you ill give you the answer anyways its the xylem. it transports water and minerals

Why roots of aquatic plant are not well developed?
Because Hydrilla being an aquatic plant absorbs water from free surface of entire plant body and need not to conduct water through xylem tissue.
Do Vascular plants have phloem?
Phloem as well as xylem
