Answer:
(C) farming fertilizers washing into lakes
What hormone helps plants move toward a stimulus?
A.)Ethylene
<u>B.)Auxins</u>
C.)Acids
Auxin moves to the darker side of the plant, causing the cells there to grow larger than corresponding cells on the lighter side of the plant. This produces a curving of the plant stem tip toward the light, a plant movement known as phototropism. Auxin also plays a role in maintaining apical dominance

Bones: they lose calcium, becoming crispy
Muscle: they lose mass
Cartilage: becomes stiffer, but it does not make airway more rigid
D) connective tissue: It includes bone, blood, and lymph tissue, giving support to the skin and internal organs, becoming increasingly stiff when aging.
It should be connective tissue.
Most fish need a minimum of 4 parts per million of dissolved oxygen in seawater to survive for long periods.
<h3>How can you mesure dissolved oxygen in water?</h3>
Dissolved oxygen (DO) is estimated utilizing a disintegrated oxygen meter or DO meter. The best strategy is to take the estimation in the field simultaneously every day, in light of the fact that DO fixations can shift all through a 24 hour time span.
Testing disintegrated oxygen (DO) in water is either estimated by means of substance examination, for example, a titrimetric technique, electroanalytical utilizing galvanic and polarographic tests, optical broke up oxygen, and colorimetric strategies.
In any case, present day procedures basically utilize electrochemical or optical sensor techniques.
The Winkler Method is a procedure used to quantify broke up oxygen in freshwater frameworks. Disintegrated oxygen is utilized as a mark of the wellbeing of a water body, where higher broke up oxygen fixations are corresponded with high efficiency and little contamination.
Disintegration of natural material,Bacterial oxidation of dead natural material consumes oxygen. This likewise makes sense of the relating expansion in supplement levels underneath the epipelagic zone.

I believe the answer is Intron IV, Introns are non-coding regions while exons are the coding regions. In most eukaryotic genes, coding regions (exons) are interrupted by non coding regions (introns). During transcription, the entire gene is copied into a pre-mRNA splicing, introns are removed and exons joined to form a contiguous coding sequence.
