Answer:
Option B, by saltation in the first few meters above the land surface
Explanation:
In the process of saltation, sand is carried by air and the sand grains remains suspended for a small distance till the fall down. These sand grains form a parabolic trajectory before falling down. The other characteristics such as height and time of suspended grains depends on grain size, shape, and density, lift & drag force and characteristics of wind such as velocity and turbulence.
Hence, option B is correct
Answer:
The correct answer will be- true (assuming the student is asking the true or false)
Explanation:
Biodiversity refers to the diversity of the biological world. The biological world is composed of the living organisms and their associated concepts.
The biodiversity represents the variety of organisms and species in an ecosystem, variety in the ecosystems and the genes which contribute to the variation in the organisms along with controlling the traits of organisms. The biodiversity is the major factor which has maintained the natural sustainability on Earth.
Thus, true is the correct answer.
Answer:
Both eukaryotes and prokaryotes have gene regulation strategies. By gene regulation, the amount of protein is maintained in the living cell.
In prokaryotes, operons are present which are controlled by a regulatory gene that regulates the synthesis of protein in prokaryotes. In eukaryotes, repressor and transcription activators regulate the expression of gene and protein formation.
So by gene regulation cell maintains the number of protein molecules to become too great for a cell. Without gene regulation the survival of any organism is not possible.
