Mecayla harvests oysters from the shallow waters of the marsh near her home. She eats the shellfish almost every day. Her brother Kendis dislikes oysters but eats local predator fish from the river three times a week. Recent water quality tests show moderate levels of heavy metals in the river and marsh. What is the most likely result of this pollutant on Mecayla and Kendis if they maintain the same diet?
Mecayla will get sick first because she eats oysters every day.
Kendis will get sick first because of less bioaccumulation.
Biomagnification will cause Kendis to become ill first.
Bioaccumulation will cause Mecayla to become ill first.
Answer: Biomagnification will cause Kendis to become ill first.
Explanation: This answer is correct because Kendis is eating the predator fish and Mecayla is only eating some oysters from the shallow water. Biomagnification causes the concentration of toxins, specifically in the predator fish, therefore Kendis will become ill first.
Mecayla harvests oysters from the shallow waters of the marsh near her home. Biomagnification will cause Kendis to become ill first.
What is the ocean?The existence of life on our planet is due to the oceans. Today, more than 230,000 marine species call the sea their home. Life began in the water.
Climate and temperature on Earth are governed by the oceans. They regulate temperatures and play a critical role in precipitation formation. The world's five oceans have a salinity that is around 3.5 percent on average.
The Mediterranean, the Atlantic, and the Bay of Bengal, on the other hand, have higher saline levels.
Therefore, Mecayla harvests oysters from the shallow waters of the marsh near her home. Biomagnification will cause Kendis to become ill first.

what happen to the matter during a phase changes
Answer:A phase change is a physical process in which a substance goes from one phase to another. Usually the change occurs when adding or removing heat at a particular temperature, known as the melting point or the boiling point of the substance. Removing heat from a substance changes a gas to a liquid or a liquid to a solid.

1. A baby’s mass was measured when the baby was born and then every month for 6 months. At 3 months of age, the baby was sick, so the baby’s mass was not measured. Create a graph by using the data table above. Use the graph to find the likely mass of the baby at 3 months.
2. Does your graph show a linear or a nonlinear relationship? Explain your answer.
Answer:
1. 5.51 kg
2. A linear relationship, because the mass-time graph have the shape of a line
Explanation:
1. The slope of the graph is 0.77, so you have to multiply it by 3 and add the initial mass of the baby:
0.77×3 + 3.2 = 5.51 kg
How does water affect Earth’s physical features?
Answer:
Water moving across the earth in streams and rivers pushes along soil and breaks down pieces of rock in a process called erosion. The moving water carries away rock and soil from some areas and deposits them in other areas, creating new landforms or changing the course of a stream or river.

which process does not occur within a mitochondrion in a eukaryotic cell?
The process that does not occur within the mitochondria of a eukaryotic cell is glycolysis. I can conclude this because I believe you are referring to the options for this question which are:
A) Krebs cycle
B) Glycolysis
C) ATP synthesis
D) Electron transport chain
Glycolysis is a process in which glucose in the cytoplasm of a cell is broken down to produce energy in the form of ATP. The word glycolysis means "glucose splitting". It is one of the stages of cellular respiration. In fact, it is what begins this process.
Glycolysis is an anaerobic process meaning it does not need the presence of oxygen to function properly. Although this is a very important process and does participate in the creation of ATP, it does not occur in the mitochondria, but rather in the cytoplasm of a cell.

energy-producing structure of the cell and
location of cellular respiration
it
Answer:
Decodes the sequence of bases on the mRNA and then creates specifc proteins
Explanation:
Decodes the sequence of bases on the mRNA and then creates specific proteins. Therefore, option (A) is correct.
Ribosomes in eukaryotic cells are responsible for protein synthesis, a crucial process in which they decode the genetic information carried by mRNA molecules. Ribosomes read the mRNA sequence and use it as a template to assemble amino acids in the correct order, forming a polypeptide chain that folds into a functional protein. This process, called translation, occurs in two main subunits of the ribosome, which come together on the mRNA strand.
Ribosomes ensure accurate protein synthesis by matching each mRNA codon with the appropriate amino acid, guided by transfer RNA (tRNA) molecules. Ultimately, ribosomes play a central role in translating genetic information from DNA to create a wide variety of proteins that perform diverse functions within the cell and organism, making them essential components of cellular machinery. Therefore, option (A) is correct.
