Answer:
<u><em>The correct option is C) genetic variation</em></u>
Explanation:
Genetic variation can be described as the differences present in the genetic material i.e DNA of organisms present in a population. Genetic diversity allows organisms of a species to better adapt to an environment. A population in which the genetic variability is scarce might become wiped out by a disease or an invading predator.
As the birds show different variations hence the term that best described them is genetic variation.
The basic components (depedent and indepedent variables) are the plants and altitude while the confounding variable is the 20 story building. Confounding variables affect the experiement variable and are mainly outside of the researcher’s control in the experiment. Ray cannot change the building but this variable can affect the depedent and indepedent variables and cause distorted or spurious results.
A plant-life filled biome of sorts, like a thick forest.
Hope this helps!
1. flask-shaped gland unbranched ducts=SIMPLE ALVEOLAR GLAND
2. slender, straight gland unbranched ducts = SIMPLE TUBULAR GLAND
3. combination of gland shapes = TUBULAR ALVEOLAR
4.branched ducts=COMPOUND GLAND (salivary glands)
All of them are the exocrine glands (their product is secreted on the epithelial surface).
Answer:
Its c ,animals ,seed wings and wind
Explanation:
There are mainly 2 ways the seeds of gymnosperms are dispersed :-
- The gymnosperms that are old become rip and their cones open up and the seeds are dispersed by the wind.There are small seed wings present on seeds that take the seed to long distance places
- The fruit of the gymnosperms gets eaten by the animals in different places as its their source of food .The seeds are not digested by the animals and excreted as a result the seed is dispersed far away from the source
