Answer:
a, a permanent thermocline traps nutrients in the deep water
b. primary productivity is high all year round, because there is a constant supply of solar energy for photosynthesis.
Explanation:
Thermocline occurs in the tropical regions because the temperature is very high which warms the upper layer of water bodies whereas the lower layer of water has low temperature due to no sunlight. The primary productivity is high all year in the tropical regions, because there is a constant supply of sunlight that is needed by the plants for preparing their own food.
Answer:
Incomplete dominance
Explanation:
Incomplete dominance is a type of inheritance pattern in which two alleles of a gene are not dominant over one another but rather form an intermediate phenotype, which is a blending of both parental phenotypes. It is a non-mendelian inheritance i.e. does not conform to Mendel's inheritance principles.
An example of incomplete dominance is that of the alleles of a flower color gene in four o'clock plant. The alleles for white (W) and red (R) are incompletely dominant over one another, hence, they form an intermediate PINK phenotype (RW).
Answer:
Punctuated equilibrium
Explanation:
The idea of "punctuated equilibrium" suggests that species will show little to no evolutionary change throughout their history. When evolution does occur, according to this idea, it happens sporadically and relatively quickly compared to the species' full duration on Earth.
A substance that releases hydroxyl ions in water is a base. Acids on the other hand release hydrogen ions when dissolved in water, while salts release sodium. To define acids and bases the Arrhenius definition is used by scientists---this describes what substances are produce by each type of solutions. Under the Arrhenius definition salt and water can be used to predict the result of the neutralization of an acid with a base.
In Chemistry, Bronsted-Lowry definition has superseded the Arrehenius definition.
TOPOISOMERASE
There are various function of DNA toposisomerase such as:
1.accessing DNA- this happens during transcription and replication, DNA must be unwound for this to happen, Topoisomerase I make a single break to create an access.
2. Removing DNA super coils- Topoisomerase prevents DNA to be supercoiled, this happens during transcription of DNA to RNA
3. Strand breakage- It can introduce single strand breaks that are required for DNA to be exchanged to adjacent chromosomes.
