Answer:
They have helical thickening of lignin in their walls to prevent collapse
Explanation:
the primary function of Xylem and its conducting vessels tracheids is to provide support and tranport water and minerals in plants.
Xylem vessels have layers of dead materials in the walls called LIGNIN. Lignin is a polymer; a very strong, hard materials that stop water passage through it,because it contains dead cells,
Therefore the presence of deposit of these strong impermeable, ligified walls in its walls prevent its collapse during mass flow of water of transpiration pull.
Answer and Explanation:
Land - Lion
Water - Sealion
Flies - Bees
Lions have strong retractable jaws that help them eat their prey and that way they adapt to their enviroment.
The Sealion's thick, oily fur and a layer of blubber allow them to keep a high temperature in cold waters.
A Bees body carries an electrostatic charge that attracts pollen and that way they can keep it in them.
Hope this Helps! Have a GREAT day!
Tactile
signals are received by the PARIETAL lobe.
This part of the brain is the one
that processes basic sensations such as temperature, touch, pressure, pain, and
stores the learnt data.
A 10-month-old baby starts to develop this part of the
brain as you can see them staring to pick up objects and explore their
surroundings.
Contraction of skeletal muscles against the lymph vessel
The lymph usually move in the body in its own vessel and travels from the interstitial spaces to the subclavian veins at the neck area. The lymphatic system does not have a heart to pump and move the fluid. The movement of lymph depends on the movements of the muscles and joints in the body. In this mechanism upward movement is possible. It will move towards the neck where it will be filtered and will go again into the subclavian veins.
