A goal of using animal models is to explain the molecular detail of specific behaviors encoded in the human brain. How would you compare the developmental biology experiments on memory and learning using the fruit fly, drosophila melanogaster, as evidence about the evolution of a human behavior?

Answers

Answer:

It is possible to compare the expression of homologous genes in the brain of D. melanoganster and humans, because the expression levels of conserved genes may be associated with the evolution of cognitive features such as complex learning and memory.  

Explanation:

Model organisms can be used to understand the patterns and processes that affect human evolution. Drosophila melanogaster is a model organism that has been used to study expression patterns of conserved genes in the course of evolution. This model organism has also been used to develop genetic mutant lines in order to examine the role of genes evolutionarily conserved in animals, including those involved in neurocognitive development.

In genetic research, an experiment as the above described is framed in a research field named 'Behavioral Genetics', which is a discipline that studies how evolutionarily conserved gene networks may be associated with neurocognitive tasks during brain evolution.

Chan Hee is inflating a basketball using an air pump. He notices that the pump gets warm as he uses it. What is a good
hypothesis that could lead to new experimentation?
If there is no air in a basketball, then it is hard to play the game.
A basketball that is inflated bounces better than one that is not inflated.
If air in a pump is squeezed more, then the air gets hotter because energy is added to it.
Basketball is more fun to play than baseball because you have to move a lot more.

Answers

Answer:

If air in a pump is squeezed more, then the air gets hotter because energy is added to it.

Explanation:

A good hypothesis in the given case is that inflating basketball is getting warmer, the more it is pumped, and as a result, it would possess more heat or more friction due to all the air being pumped into the basketball at a single time.

In the text area below describe the function of the
cell wall.
DONE

Answers

The cell wall gives cells shape, enables plant growth, prevents bursting from water pressure, keeps out water and pathogens, stores carbohydrates and sends signals to cells. The flexible cell wall surrounds plant cell membranes.

Plant cell walls perform many functions. Their main task is to support proper plant growth. This is accomplished by the cell wall creating a skeleton-like frame that enables plants to grow vertically and develop a rigid stem. Cell walls vary considerably in thickness and organization, which accounts for the wide range of plant shapes and sizes on the planet. They consist of two layers ‰ÛÓ a primary cell wall, which supports the cell as it matures, and a rigid secondary cell wall that appears after the primary wall stops growing. The primary cell wall is thinner and more flexible than the secondary wall. Internally, the primary and secondary walls have a similar physical composition. Over the course of a plant's life, they perform complementary functions to keep the plant healthy and vibrant.

Answer:

The cell wall supports and protects the cell, determines the shape of the cell, assists cells in communication, stores carbohydrates, and allows water and smaller particles to enter the selectively permeable structure of the cell.

in order to survive in its environment a single celled organism uses a contractile vacuole to remove excess water that diffuses into its cell. Another species a hydra also excretes excess water. Both processes involve the use of energy. Based on this information, state whether these two organisms live in fresh water or salt water support your answer

Answers

Answer:

They would live in salt water.

Explanation:

Salt water is a hypertonic solution where water needs to move outside of the cell because there is too much solute outside. Because the 2 organisms are removing excess water, it shows that they are living in salt water where water flows outside instead of inside the cell.

Based on the available information, these two organisms would:

Live in salt water

According to the given question, we can see that there is a need for survival which makes a single celled organism to make use of the vacuole to remove the excess water which it diffuses into its cell.

As a result of this, we can see that another specie, a hydra also excretes excess water which involves the use of energy.

Therefore, the conclusion we can reach about them is that they are living in salt water because it is a hyper tonic solution which allows water to move freely outside the cell because of the excess solute outside the cell wall.

Answers

Answer:

1.33 dandelions per square meters

Explanation:

The correct answer would be 1.33 dandelions per square meter of land.

Size of quadrat = 1.5 square meters

Average number of dandelions per quadrat = 2

Total study area = 4500 square meter

Population density = number of organisms per unit area

There were 2 dandelions per 1.5 square meters

How many would be per square meter?

= 2 x 1/1.5 = 1.3333 dandelion per square meters

To 2 decimal places = 1.33 per square meters

When multiple glaciers start their downward flow from a single point, they create a .

Answers

Answer:

They create a Mountain Peak

When multiple glaciers start their downward flow from a single point, they create a Mountain peak. So, the correct option is B.

What are Glaciers?

A glacier is a sizable, slowly moving mass of ice that develops over a considerable amount of time as a result of the buildup of snow and ice. In areas where the average temperature is below freezing and there is enough snowfall to offset the melting that takes place during the summer, glaciers can be discovered. They can occur at lower elevations in some places, although they are mainly found at high altitudes or in the polar regions.

When several glaciers begin to flow downward, they build something resembling a pyramid. The mountain peak is created as a result of the glacier's movement from a single location. Due to the simultaneous movement of several glaciers to the ground, a pointed structure has recently created.

Therefore, the correct option is B.
