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: 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.

The three ecosystem services that insects provide are dung burial, pest control, and pollination.

What is an ecosystem?

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

what percentage of genetic information is passed on from parents to their offspring

Answers

Answer:

50% from each parent

Explanation:

The percentage of genetic information passed on from parents to their offspring is 50% from each parent, for a total of 100%.

What is the percentage of genetic information?

Approximately 50% of genetic information is passed on from each biological parent to their offspring. This occurs through the combination of genetic material during fertilization, where half of the offspring's genetic material comes from the mother and the other half from the father.

However, the exact percentage of genetic information passed on can vary due to factors such as genetic mutations and recombination during meiosis.

This occurs through the process of sexual reproduction, where each parent contributes one gamete (sperm or egg) containing half of their genetic information.

When the sperm and egg combine during fertilization, they form a zygote with a complete set of genetic information (100%), half from each parent.

If rainbow trout are eating all the macroinvertebrates, then keeping rainbow trout out of new river habitats will allow native species to recover. If rainbow trout are eating all the macroinvertebrates, then introducing them to other streams will help native species recover. Rainbow trout will eat a variety of macroinvertebrates and native fish species. Rainbow trout hunt and prey upon native fish species.

A possible hypothesis here is; "If rainbow trout are eating all the macroinvertebrates, then keeping rainbow trout out of new river habitats will allow native species to recover."

A hypothesis is a statement that is tentatively put forward to explain an observation. Usually, a hypothesis is an if .... then statement. This is one of the first things that we must look out for when considering each of the statements.

Since we have observed that rainbow trout eating all the macroinvertebrates in streams and starving out other fish species, it follows that  keeping rainbow trout out of new river habitats will allow native species to recover."

Explanation:

if blood calcium levels drop below 8.5 mg/dl which hormone is likely to be activated?

Answers

Answer:

Parathyroid Hormone (PTH)

Explanation:

The major function of the parathyroid glands is to maintain the body’s calcium level in both the blood and bones.

There is a narrow range of calcium required for the nervous and muscular systems to function properly. (A normal calcium level in the blood stream ranges from 8.5-10.2 mg/dL ).

When blood calcium levels drop below a certain level, receptors in the parathyroid gland release parathyroid hormone (PTH) in proportion to the amount of calcium that is required by the body. This hormone increases blood calcium levels by stimulating osteoclasts to release calcium by breaking down bone. Osteoclasts are cells in the bones that break down and remodel bone tissue.
