Answer:
a. Biomagnification
Explanation:
Biomagnification is the name given to the progressive accumulation of substances from one trophic level to another along a food chain. Thus, the substance will have its highest concentration in individuals who occupy trophic levels furthest from producers.
For biomagnification to occur, substances must be fat soluble (lipid soluble) and thus adhere to living tissues. Another feature of substances that undergo biomagnification is that they are generally not biodegradable or metabolized by the body.
The phenomenon is quite common with heavy metals (lead; mercury) and certain chlorinated and aromatic organic compounds with higher molecular mass, such as the insecticide DDT.
Earths lithospere is solid and sits on top of the softer asthenosphere.
Answer:an earthquake
Explanation:an earthquake is a violent shaking of the ground and it also creates greate destruction
Answer:
1. At the end of S phase- 20 pg DNA
2. At the end of G2 phase- 20 Pg DNA
Explanation:
The cell before undergoing M phase undergoes the steps of interphase that is G₁, S and G₂ phase.
During S phase, the process of cell replication takes place which replicates the DNA as a result of which the amount of DNA doubles. This DNA amount is reduced to half during the anaphase stage of M phase.
In the question since the amount of DNA is 10pg therefore the amount will be double during S phase and becomes 20 pg and will remain 20 pg until the DNA is distributed therefore at the end of G₂ phase Will remain the 20 pg.
Answer: The answer is A: The Inferior Colliculus
Explanation:
The inferior Colliculi play a major role in hearing. Since the loud noise was what prompted the response it is safe to say the inferior Colliculi is responsible.
Neurons in the inferior Colliculi respond to cues such as intensity, the difference red in arrival of sound to both ears.
However, the head snaps up because the information from the inferior Colliculi is transmitted to the superior Colliculi which is involved with movement such as the head.
