Answer:
Oxygen Depletion
Explanation:
In addition to the eutrophication of water bodies, wastewater effluents also contribute to another process of deoxygenation. The biological (bacterial) breakdown of organic solids in the effluent also consumes dissolved oxygen – the biological oxygen demand (BOD). In addition, the degradation of chemicals in the effluent removes oxygen from the water through chemical reactions – the chemical oxygen demand (COD).
As was previously mentioned, the loss of dissolved oxygen in the water can result in serious immediate, short-term, or long-term consequences to aquatic life. Fish survival is particularly affected by low oxygen levels. Decreased disease resistance, reduced growth, altered swimming behaviour, feeding, migration, and reproduction, increased threat of predation, and even rapid death are some of the effects of low dissolved oxygen concentrations.
Low oxygen levels can also alter the kinds of species present in the ecosystem. With a change in food supply, some populations of species decrease, while others increase. Fish such as whitefish, walleye, and pike may disappear, while bottom-feeding fish such as carp may increase in number.
As a result, you would expect to observe elevated vasopressin levels.
<h3>
What are vasopressin levels?</h3>
- A nonapeptide produced in the hypothalamus is known as vasopressin, antidiuretic hormone (ADH), or arginine vasopressin (AVP). It has long been recognized by science to play crucial roles in the maintenance of the body's osmotic balance, control of blood pressure, maintenance of salt homeostasis, and renal function.
- It is hardly surprising that ADH is of major clinical significance given its critical role in numerous activities. ADH primarily influences the kidney's capacity to reabsorb water; when present, it stimulates the production of water transport proteins in the collecting duct and late distal tubule to boost water absorption.
- When the body can no longer regulate ADH secretion or reacts to its existence, several disease states can develop.

Answer:
major event of anaphase is the sister chromatids moving to opposite poles of cells due to action of the condensing spindle fibres.
Explanation:
the chromatids only start separating when the pressure is sufficient to split the centromere.
Depending on the F1 generation (parent) phenotype we can determine whether or not it is homozygous or heterozygous. Also, check to if the F2 grey seeded plant is a mixture of Black and white or if grey is a dominant color. If it is a mixture, it would make it heterozygous. If not and Grey is domminant it would make it homozygous.
