Answer:
Increases
Explanation:
The concentration of mercury will increases as it moves up the food chain because of biomagnification. For example, a school of small fish consumes a minute amount of mercury each, but then a larger fish eats five of the smaller fish. After this the larger fish has more mercury in its system than one small fish because it ate five small fish (along with the mercury in each of the small fish). Now a seal eats multiple large fish. Overall, the seal has the highest mercury concentration out of all the animals mentioned.
Biomagnification is "the concentration of toxins in an organism as a result of its ingesting other plants or animals in which the toxins are more widely disbursed."

Which of the following statements about the flow of energy in nature is not true?
A. A large amount of energy in food is needed for bodily function
B. A major portion of the energy from food is used to keep our bodies warm
Only a small portion of the energy from food is used to keep our bodies warm or for other bodily functions. Most of it is lost as heat or through other processes.
When answering questions on Brainly, it is important to always be factually accurate, professional, and friendly. It is also important to be concise and avoid providing extraneous details, while also taking care to address all parts of the question.
Typos and irrelevant information should not be ignored. In the case of the provided question, the answer is option B: A major portion of the energy from food is used to keep our bodies warm. This is not true in the context of the flow of energy in nature.
The flow of energy in nature involves a constant transfer of energy from one organism to another in an ecosystem. Energy enters an ecosystem through primary producers like plants, who convert sunlight into food through photosynthesis.
This energy is then transferred to herbivores, who are then eaten by carnivores. As energy flows through the food chain, only a small amount of energy is transferred from one trophic level to the next.
The majority of the energy is lost through respiration, heat loss, and other metabolic processes.

Which of the following is not a function of tRNA
Answer:
connecting amino acid together to form proteins
hope it will help
Option D is correct. "connecting amino acid together to form a protein" is not a function of tRNA
Unlike DNA, there are three types of RNA that are involved in protein synthesis, messenger RNA, ribosomal RNA, and transfer RNA.
Ribosomal RNA (rRNA) and transfer RNA (tRNA) are not copies of the info in DNA, instead, their codes are created while in the DNA and then cut into smaller coded fragments.
Transfer RNA (tRNA) is found in cells' cytoplasm and ensures the correct amino acids are carried to mRNA codons to form polypeptide chains during protein synthesis. tRNA takes the amino acid to the correct location for protein synthesis in the ribosome.
Some of the functions of tRNA include:
Picking up amino acid specified by the codonTranscribing nitrogen bases into mRNA in the nucleus Recognizing appropriate codon in the mRNAAccording to the explanation above, we can see that "connecting amino acids together to form a protein" is not a function of tRNA

Why would a normally aquatic or marine species adapt to the supralittoral fringe where they have to deal with desiccation and temperature stress?
Answer:
In order to survive.
Explanation:
A normally aquatic species adapt to the supralittoral fringe in order to survive in that environment. Supralittoral zone also referred to the area on coastlines and estuaries, that is regularly splashed, but not submerged by ocean water. This environment is different for the marine organisms that causes adverse effect on the marine organisms but these marine animals has the ability to adapt that environment by using certain mechanism in order to survive and easily reproduce in that environment.

The three tenets to the cell theory are as described below: All living organisms are composed of one or more cells. The cell is the basic unit of structure and organization in organisms. Cells arise from pre-existing cells.
Explanation:
Can I have brainliest?
Answer:
Answer: 1) All the living organims are compound by one or more cells . 2) The cell is the structural and functional basic unit of life. 3) All cells are originated from other cells.
Explanation: Cell theory describes the characteristics of living organisms and was proposed and refined by many scientists like Schwann and Schleiden. The first principle describes the constitution of living organisms, all of them, unicellular or multicellular are compund by cells. The second principle says that cell is the unit of life in fuctions as metabolism and structural as in tissues. The third principle says that cells can only be generated by division of preexisting cells.

what is hormone injection and subcutaneous implants??
Explanation:
The contraceptive injection is a shot that contains hormones, either a progestin alone, or a progestin and an estrogen together, that stop your body from releasing eggs and thickens the mucus at the cervix. You need one shot either once every month or once every three months from a healthcare provider. However once injected, it is not reversible, i.e. in case of side effects it cannot be stopped. The way it works is similar to the pill, or the ring, except you don’t have to remember to take it every day or week, but it probably isn’t the best choice for those scared of needles.

Which of the labeled structures is an adaptation that is primarily responsible for helping a paramecium control its water balance?
Paramecium diagram
A. Structure A
B. Structure B
C. Structure C
D. Structure D
Structure D , The term "contractile vacuole" refers to this structure. The vacuole gathers extra water from the cytoplasm and contracts to release it. As a result, paramecium doesn't swell and explode in hypotonic liquids.
Why are contractile vacuoles necessary for organisms?Specialized contractile vacuoles control the amount of water in cells. Its spherical form allows it to gather extra cell fluid and empty it outside. It is essential for preserving the osmotic pressure inside the cell. Protists are eukaryotes with only one cell and are found in wet and aqueous habitats.
The name "contractile vacuole" refers to what?As its name implies, the contractile vacuole expels water from the cell by contracting. The contractile vacuole periodically expands (collecting water) and contracts (releasing water). Several seconds are required for one cycle, depending on the species .
