Answer:
Secondary consumers.
Explanation:
In a trophic pyramid, there are conventionally four levels. From the bottom they are: Producers, Primary Consumers: Secondary Consumers, and at the top we have tertiary consumers. Each level generally consumes animals in the level below it. Producers consist of plants.
Answer:
D. In autopolyploidy, one parental species contributes to the polyploidy; in allopolyploidy, two parental species contribute to the polyploidy.
Explanation:
Autopolyploidy is the polyploidy that arises when the organisms have more than two complete sets of the same genome. For example, if a diploid species is represented as "AA", its autopolyploid with four complete sets of the genome can be represented as "AAAA".
On the other hand, allopolyploidy occurs when the polyploid carries more than two complete sets of the genome from separate species. For example, if two diploid species are represented as "AA" and "BB", their allopolyploid with four complete sets of the genome can be represented as "AABB".

Answer:
Phosphorus is essential for growth of plants and other organisms. When concentration of phosphorus mostly from high breeding rate e.g., pigs, cattle etc. rise in water it causes severe growth of plants and algae as well as phytoplanktons. As a results layers of phosphorus start to release phosphorus as well due to positive gradient. These reactions in water are iron-redox reactions that are crucial for the release of phosphorus.
When too much phosphorus accumulates, it produces a degrading growth feedback in plants, algae and phytoplanktons that then shift toward excessive nitrogen available from fertilizers and cause a flip from P to N. Cynobacteria now dominates and denitrification as well as nitrification takes place simultaneously.
Severe eutrophication induces hypoxia in water that cause a major damage to plants biodiversity in the environment.
Boston is colder than Miami.
Therefore, more water is lost in the form of sweat in summer than in winter. In the summer, your body becomes dehydrated, releasing more ADH in your body.
ADH Syndrome of antidiuretic hormone or vasopressin is synthesized by the hypothalamus and released from the posterior pituitary gland to maintain blood osmolality. It increases the reabsorption of water from the kidney nephrons.
Therefore, in a cold environment like Boston, ADH will be low and will increase significantly in Miami.
Several chemicals change ADH levels.
Drugs that raise ADH levels include vasotrict and vasopressin.
Drugs that lower ADH includes alcohol.
Therefore, some chemicals can affect ADH levels in the blood.
