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.

Answers

Answer 1

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.

Answer 2

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.

Answers

Answer:

Explanation:

Sister chromatids

During DNA replication the chromosomes contract and the identical halves are called sister chromatids.

What is DNA replication?

A double-stranded DNA molecule is copied to create two identical DNA molecules through the process of DNA replication.

Because every time a cell splits, the two new daughter cells must have the same genetic material, or DNA, as the parent cell, replication is a crucial process.

In prokaryotes, DNA replication takes place in the cytoplasm, whereas it happens in the nucleus in eukaryotes.

Before dividing, cells must copy their DNA. This promotes successful inheritance of genetic features by giving each daughter cell a copy of the genome.

The two identical copies of the DNA that are produced as a result of this replication are known as "sister chromatids," and they are connected to one another by a section of the chromosome known as the centromere.

Thus, the identical halves of chromosome is sister chromatid.

Materials like coal, wood, oil, or gas can provide heat when burned. Methanol, Gasoline, Diesel, Propane, Natural gas, Hydrogen are types of fuel. Nuclear energy is produced by burning plutonium.

From fuel efficiency or fuel economy, we can measure how long any vehicle could travel, which is the opposite of fuel consumption.

Fuel consumption is the amount of fuel vehicle uses to travel a particular distance.

Fuel efficiency can be measured in kilometers per liter. The efficiency with which the fuel does a conversion of energy is known as fuel efficiency.
