Superficial is a used to describe structures that are closer to the exterior surface of the body. Deep refers to structures closer to the center of the body region. For example, skin is superficial to bones, and bones are deep to skin.
Organisms that originated in a certain geographic region and can only be found in that region are said to be endemic.
Explanation:
Endemic organisms are taxonomic species (plants and animals) which originates and distributed only in specific geographic regions. This state of evolution is called endemism.
They are said to be native or indigenous to that particular region which can be an ecological habitat, an entire nation, an island, a mountain range etc. Certain parts are known for majority of their species being endemic like St. Helen Island, New Caledonia Island, Hawaiian Islands, Southern regions of Africa, and Australia.
The species becomes endemic to a particular region because of the presence of certain bio-geographical environmental qualities of that habitat which are favorable to that species.
When these conditions become unfavorable, then species becomes restricted leading to endangerment or extinction of the species.
Examples:
- Kangaroo - Australia
- Nilgiri Tahr, - Nilgiri Hills, India
- The Redwood trees of West Coast of the USA
- Plants like kalo, sumac of Hawaii
Explanation:
Standard volume=22.4 L
It means that 1 mole of any atom, molecule or ion occupies 22.4 L of volume at STP (Standard Temperature and Pressure)
1 mole of CO2 = 22.4 L
Given volume = 224 mL = .224 L ( 1 L = 1000 mL)
No. of moles in .224 L = Given volume/Standard volume
= .224/22.4 = 0.01 mole
After fertilization of the ovule, the megaspore develops into the food supply of the mature seed.
After fertilization of the ovule, the <em />integument develops into the seed coat.
After fertilization of the ovule, the fertilized egg develops into the embryo of the mature seed.
The ovule contains the female reproductive cells of the seed plants and when fertilized, it produces the seed. Ovules contain megasporocytes, cells that produce megaspores through cell division. An integument is a layer that protects and surrounds the ovule. After fertilization, the integument protects and surrounds the seed. After fertilization, the ovule contains a diploid zygote which develops into an embryo.
Answer:
Sea water
Explanation:
Because sea water has many impurities
