<h3>⇝ <u>Epidermis</u> :</h3>
Protective tissues includes epidermis & cork. Epidermis is basically a simple permanent tissue, protective in function. It forms one-cell-thick covering over all the parts of plant.
<h3>⇝ <u>Characteristics of Epidermis</u> : </h3>
- Epidermis is formed of living cells, arranged in a single layer.
- In aerial parts, epidermis is covered with a waterproof and noncellular waxy covering called cuticle.
- Cells form a continuous layer, but in leaves epidermis has small openings called stomata.
- Each stoma is guarded by a pair of bean-shaped guard cells which govern opening & closing of stomatal aperture.
<h3>⇝ <u>Functions of Epidermis</u> :</h3>
- Epidermis protects the underlying tissues from mechanical injury, chemicals & infection.
- Cuticle of epidermis protects against water loss & desiccation. It checks the rate of transpiration & evaporation and prevents wilting.
- Stomata in the epidermis of leaves help in gaseous exchange during respiration & photosynthesis.

Answer:
By action potential nerve contract the muscle
Explanation:
The muscle contract when the nervous system sends action potential to the muscle. So the nervous system delivers signal to muscle, the first signal reaches the neuromuscular junction. The signals are passed by a chemical messenger called neurotransmitter release by motor neurons, the chemicals bring reaction and shorten the muscle fibre. When neurotransmitter are absent or reduce in concentration the process reverse and muscle relax again.
The difference between an amniotic egg and eggs laid by other animals is : Absence of Membrane ( amnion ) and absence of larval stage
<h3>Characteristics of an amniotic egg</h3>
Eggs laid by amniotes are different from other eggs laid by fishes, amphibians and invertebrates in that they lack a membrane and a larval stage. the shell of the amniotic egg protects the embryo in the absence of a membrane. The shell also allows for the exchange of oxygen and carbon dioxide between the the embryo and the environment.
Hence we can conclude that The difference between an amniotic egg and eggs laid by other animals is : Absence of Membrane ( amnion ) and absence of larval stage

Answer:
saturated
Explanation:
saturated fats have straight tails. you give a good but not easy to find the answer, example.
Answer:
The key difference between kingdom and domain is that the kingdom is one of the five major groups of living organisms while the domain is one of the three taxonomic categories of living organisms above the kingdom level.
These are the similarities between kingdom and domain:
1)Kingdom and domain are two types of categories to classify living organisms.
2)Kingdoms are coming under the domains.
3)All living organisms belong to three domains as well as to five kingdoms.
Explanation:
You can write any one of the similarities!
