Ecosystems Unit Test 8 of 8 Items Item 8 Discuss an ecosystem in which there is a producer, a consumer, a secondary consumer, and a decomposer. Name the ecosystem and specific organisms for a producer, consumer, secondary consumer, and decomposer

Answers

Answer 1

Answer:

The ecosystem, in this case, is a forest. The producers are plants. The deer, who eats the plants, is the consumer. The wolf, who eats the deer, is the secondary consumer, and earthworms are the decomposers.

Explanation:

An ecosystem is a group of beings that are in a certain area where they interact with each other and with their surroundings. In this case, we describe a trophic level with beings that are in the forest.

Producers are beings that produce their food, like plants.Consumers or primary consumers are animals that eat producers. They are herbivores.Secondary consumers eat primary consumers. They can be omnivores, or like in this case, carnivores.Decomposers are bacterias, mushrooms, or earthworms. They act on all levels breaking down the rest of the animals and plants, obtaining nutrients to nourish the soil, and start the cycle again.

What is deforestation?

Deforestation refers to the loss of forest area worldwide to other uses such as agricultural land, urbanization and mining activities. Deforestation, greatly accelerated by human activities since the 1960s, has adversely affected natural ecosystems, biodiversity and climate.

Several factors, both human and natural, cause deforestation. Natural factors include natural forest fires and diseases caused by parasites that can lead to deforestation. Nevertheless, human activities are one of the main causes of global deforestation.

Therefore, If everyone reduce the use of papers it will lead to reduce in deforestation.

Staphylococcus aureus, or staph, is a bacteria that is commonly found in the nose and on the skin of humans. While it is typically not harmful to humans, it is sometimes able to enter the body through an injury or broken skin, and get into the bloodstream. When this happens, it can cause a serious infection called sepsis. Sepsis can cause an individual to go into shock and bodily organs to stop functioning. Symptoms of sepsis include inflammation, fever or hypothermia, increased heart rate, and rapid breathing.

A microscopic image of staphylococcus aureus is shown.

A scientist observed that during the course of a chemical reaction the number of ATP molecules were converted into ADP. What did the scientist most likely learn from the observation? a The reaction caused an output of energy. b The reaction produced water. c The reaction consumed water. d The reaction required an input of energy.

Answers

Answer:

a The reaction caused an output of energy

Explanation:

Adenosine triphosphate, commonly known as ADP, is an high-energy storage molecule in living cells. It stores and transfers needed energy for metabolic activities. ATP stores its energy in the bonds that hold the phosphate group in its structure. However, the energy is released for use during metabolic processes when the phosphate bond is broken, leading to the release of ADP molecule.

In this case, a scientist observed that during the course of a chemical reaction the number of ATP molecules were converted into ADP. This means that the reaction has caused ATP molecules to release its stored energy i.e. an energy output.

If you say that a ground squirrel has greater evolutionary fitness than another ground squirrel in the same population, you mean that the animal

Answers

Answer:

Has more offspring that have the ability to survive and reproduce themselves.

Explanation:

Evolution fitness can be defined as a characteristic or quality possessed by living organisms and determines their adaptability, as well as level of success in terms of reproduction i.e giving birth to offsprings.

Hence, if you say that a ground squirrel has greater evolutionary fitness than another ground squirrel in the same population, you mean that the animal has more offspring that have the ability to survive and reproduce themselves.

Why did Mendel study pea plants?

They reproduce asexually and have one trait that is easy to observe.
They reproduce asexually and have many traits that are easy to observe.
They reproduce sexually and have one trait that is easy to observe.
They reproduce sexually and have many traits that are easy to observe.

Answers

Answer:

For Gregor Mendel, pea plants were fundamental in allowing him to understand the means by which traits are inherited between parent and offspring. He chose pea plants because they were easy to grow, could be bred rapidly, and had several observable characteristics, like petal color and pea color.

Explanation:

Gregor Mendel chose the pea plants for his experiments because the garden pea is an ideal subject in the study of genetics for the following reasons: The presence of observable traits with contrasting forms. It produces many offspring in one cross. Short life cycle.

Why did Mendel choose pea plants to study?

Solution: Pea plants were chosen for Mendel's experiments because they are easy to grow, have a short life period, and produce larger flowers. Pea plants are also self-pollinated.

What was the purpose of the pea plant study?

Gregor Mendel describes his experiments with peas showing that heredity is transmitted in discrete units. From the earliest time, people noticed the resemblance between parents and offspring, among animals and plants as well as in human families. Gregor Johann Mendel turned the study of heredity into a science.

If the mrna is damaged, it directly interferes with the ability of a animal cell to do which of the following?

Answers

Answer:

Proteins.

Explanation:

If the mRNA is damaged, it directly interferes with the ability of producing proteins in animal cell because mRNA is responsible for carrying the protein blueprint from a cell's DNA to its ribosomes which are considered as the machines of the cell that produces proteins for the cell. These messenger RNA has the information about what type of proteins are required to produced for the cell. So if mRNA is damaged, the ribosomes are unable to produce proteins for the cell.

Immunity to Small Pox

Explanation:

Over the years, Europeans had built up an immunity to smallpox because many had contracted the disease and still survived. As the population grew children were born with some immunity to the disease. When the Europeans arrived in the Americas, and smallpox spread around the native peoples, the Europeans did not contract the disease because they were immune. However, since the natives were not immune, they slowly died of due just to the disease as well as some parts of the war between the europeans.

A girl is born with hemophilia. Her dad also has hemophilia, but her mother does not.

What genetic explanation can you provide as to why the girl
suffers from hemophilia?

Answers

answer:

So daughters get 2 X chromosomes from the mom and dad and if the dad has hemophilia the daughter would get it too and sons would not get because they get Y chromosome from their dad and hemophilia is found in the X chromosome because the X chromosome is the one that has the instructions for making the clotting factor proteins.

Explanation:

A father who has hemophilia has the gene and passes it on to his daughter because daughters get two X chromosomes, one from their mother and the other from their father. This is why daughters of men with hemophilia are called obligate carriers. Since sons only receive a Y chromosome from their father, they would not have inherited hemophilia.

What is the significance of amino acids?

There are 20 different standard amino acids that take part in polypeptide chain synthesis, and those are categorized into some particular types such as hydrophobic amino acids, hydrophilic amino acids, charged and uncharged amino acids, etc., and different compositions of the amino acids make different types of proteins. The polypeptide chain is generally synthesized from the N terminal to the C terminal, and here in the given diagram, there are four amino acids, and each amino acid has an amino group, a carboxylic group, a hydrogen group, and one side chain bonded to a single central carbon atom.

Hence, the given segment of the polypeptide chain is made up of four different types of amino acids.
