In a species of Drosophila, developing larva have special proteins in their epithelial cells. These proteins bind to a certain r

epressor in the larva's cells, which ultimately causes a dark pigment to be produced. What would you expect if scientists purposely injected a developing larva with an excess of these proteins?

Answer:

The larva gets dark pigment.

Explanation:

If scientists purposely injected an excess concentration of these proteins in the larva, the larva gets deep dark colour because this protein is responsible for the pigment colour in the larva of Drosophila. By increasing the protein concentration the pigment will also have a very dark colour. So we can conclude from this that increasing the amount of protein causes increase in the pigment colour.

Population density refers to the determination of population in a unit area or unit volume. It is generally applicable to the living species, and majorly to the humans. It is an essential geographical term and its a quantity of type number density.  

In the given case, it can be seen that New Zealand exhibits a smaller population in comparison to Australia, but it has a greater population density as it encompasses a much smaller region.  

On the other hand, the population of Australia is about five times more than New Zealand, but Australia covers about 30 times more area in comparison to what New Zealand covers.

What stores the most energy?
stich3 [128]
In terms of macromolecules, needed and utilized by organisms to carry out essential metabolic chemical reactions and for maintaining structure would be Lipids.

Lipid based molecules or Fats tend to store the most energy, as breaking chemical bonds connecting fatty acid chains of long hydrocarbons releases quite a bit of energy.

larisa [96]

Hello, I did this project in seventh grade, and I still have my notebook from it! Here's the answer I wrote:

<u>A cell is like a restaurant.</u>

The cell membrane controls what goes in and out of the cell. It is like a door because it get things in and out of the cell, much like a door gets people in and out of a restaurant.

The chloroplast makes food for the cell by photosynthesis. It is like the chef because it makes and provides food for the cell, much like a chef makes food for the customers.

The nucleus controls the activities of the cell. It is like the kitchen becuase it holds information in the cell, and the kitchen holds all of the recipes.

The endoplasmic reticulum transports materials around the cell. It is like a waiter because it transports things around the cell, like a waiter transports food around the restaurant.

The mitochondria give the cell energy by breaking down food. It is like a customer becuase it breaks down food and provides energy to the cell, much like how customers eat food that the chef makes and then pay for it, so the business does well.

The cytoplasm holds the organelles and is where chemical reactions take place. It is like the building because it holds all the organelles in the cell, and the building holds all of the restaurant activity.

The vacuole stores food, water, and waste. It is like the refrigerator because both store water and food.

The Golgi bodies pack, fold, and deliver proteins. They are like the take-out boxes in a restaurant because they hold proteins, and take-out boxes pack and hold food.

I really hopes this helps!
