Explain how the first three steps of scientific inquiry are related..

Answers

The first three scientific inquiry is being related because
 they are all equivalent to the facts of finding emission.

They develop a question that must be answered.
1. The first scientific inquiry is to pose a question or else a problem is being investigated.
2. The next step is the observation, and it helps to form a hypothesis which explains the phenomenon or effect of what is observed.

Scientific inquiry is the diverse ways in which scientist study the natural world and then propose the explanations which are based on evidence which is derived from their work. Also, students develop science ideas of knowledge and understanding how scientist they do study the natural world.

A cell is placed in a water solution with the same salt concentration as the cell. The cell is placed in a _____.

Answers

The right answer is an isotonic solution.

An isotonic solution is a system in which the osmotic concentration is the same as the solute concentration of a cell. In this case, the cell does not swell or shrink because there is no gradient of water concentration across the cell membrane.

The water molecules diffuse across the plasma membrane in both directions, and the rate of water diffusion is the same in each direction of this cell without gaining or losing water.


Isotonic solution. Since it has the same salt concentration as the cell the solution is neither hypotonic or hypertonic.

Cells such as nerve and muscle cells contain more mitochondria than other cells. why? A) Nerve and muscle cells use more energy. B) Nerve and muscle cells store more nutrients C) Nerve and muscle cells degrade more proteins. D) nerve and muscle cells divide more frequently

Answers

Answer:

A) Nerve and muscle cells use more energy

Explanation:

Mitochondria are located near sites of high ATP utilization such as in muscle cells and neurons.

In the cells of the heart muscle these mitochondria are located near the contractile apparatus, which is where the hydrolysis of the ATP is carried out to generate the necessary energy in the contraction. In musculoskeletal cells the number of mitochondria is increased between 5 and 10 times when the muscle is exposed to continuous contraction.

In the neuronal cells there is a high workload suffered by the cell and a high energy expenditure

A) Nerve and muscle cells use more energy is the correct answer because the function of mitochondria is to produce energy for the cell.

Describe how mendel showed that the green-seed trait did not disappear but was only masked. Please help me :)

Answers

Mendel showed that the green-seed trait did not disappear but was only masked by breeding plants with only two alleles for the trait. After the cross of yellow seed, a small amount of offspring had green seeds. So, he concluded that the green-seed trait is masked by the dominant yellow-seed trait and that two alleles are necessary for green-seed trait to show up.

Introducing additional organisms of the same existing kinds will not upset the ecosystem.true or false

Answers


false, because if you add additional organisms, the food web would become lopsided, causing the organisms food to decrease.
false it will need to eat food so if it eats blueberries the animals that eat blueberries will be affected and it needs water and shelter it can even bring down a ecosystem.

Which of the following forest management practices is the most harmful to forest ecosystems? a. clearcutting b. shelterwood cutting c. group selection d. single tree selection please select the best answer from the choices provided a b c d

Answers

Answer:

a. clearcutting

Explanation:

Clearcutting is the most harmful forest management practice to forest ecosystems. Clearcutting involves removing all trees in a designated area, leaving the land completely bare. This practice has negative impacts on the ecosystem as it disrupts the natural processes and functions of the forest. It can lead to soil erosion, loss of habitat for various plant and animal species, and changes in the microclimate of the area. Clearcutting also reduces the overall biodiversity of the forest and can take a significant amount of time for the ecosystem to recover.

Final answer:

Clearcutting is the most harmful forest management practice as it disrupts the natural ecosystem and can lead to soil erosion and loss of habitat.

Explanation:

The most harmful forest management practice to forest ecosystems is clearcutting. Clearcutting involves removing all trees within a certain area, leaving the land bare and disrupting the natural ecosystem. This practice can lead to soil erosion, loss of habitat for wildlife, and changes in water availability. On the other hand, shelterwood cutting, group selection, and single tree selection are methods that are more sustainable and less harmful to the forest ecosystem.
