Answer:

Use the rule that 10% of the energy is transferred between layers.

Explanation:

Energy is transferred between layers of a food pyramid. That means that the producers at the bottom of the pyramid (e.g. green plants) provide energy to the primary consumers (e.g. rabbits), which are eaten by and provide energy to the secondary consumers (e.g. foxes).

However, very little of the energy is actually transferred to the next layer, roughly 10%. So an easy way to calculate the energy available at each level is to calculate 10% of what was available from the previous level. So if there is 600 kJ available from the primary consumers, then 60 kJ are transferred to the secondary consumers

How do the specific characteristics of carbon, hydrogen and oxygen enable the

earnstyle [38]

Carbon makes four electrons available to form covalent chemical bonds, allowing carbon atoms to form multiple stable bonds with other small atoms, including hydrogen, oxygen, and nitrogen. This allows carbon atoms to form a tremendous variety of very large and complex molecules.

Why do cells which lack cell cycle control exhibit karyotypes which look physically different than cells with normal cell cycle?

avanturin [10]

A karyotype is the number and appearance of chromosomes in the nucleus of an eukaryotic cell. Karyotypes also describe the chromosomes count of an organism and the appearance of these chromosomes under the microscope. Cell which lack cell cycle control are often cancerous cells and they look different under the microscope compared to the normal cells. Cancerous cells will look different under the microscope in term of number of chromosomes, size, length, positioning and general appearance.

Some people seem more willing to openly display prejudice regarding sexual orientation than prejudice regarding race and gender.

STALIN [3.7K]

Answer:

Some people offer more prejudice on the sexual orientation because sexual orientation like gay marriages were not seen in the world before. Before the 21st century, the same- sex marriage was never seen or heard about. So, today people display more prejudice regarding this issue because sexual orientation began in the 21st century. Many people are of the view that this same sex marriage is not traditional and hence it is not right morally. While others believe that every person has the right of freedom and this is their civil right to do what they like.

The discrimination based on race and gender has been an issue from the start of human lives. Almost every country has a history which shows race and gender discrimination. Hence, though majority of the people today are against this but still is is not as a hot and new topic for prejudice as the topic of sexual orientation is.

For a science experiment. John gradually added a sedium hydroxide (NaOH) solution to warm vegetable oil in a glass test tube. He

Marrrta [24]

The sodium hydroxide solution and vegetable oil underwent a chemical change.

<h3><u>Explanation:</u></h3>

The reaction between a base and a fat or fatty acid is called as saponification reaction. Here the base dissociates into the cation and hydroxyl ion. The hydrogen from the fatty acid of the oil reacts with the hydroxyl ion to form water which is basically the neutralization reaction. This cation now reacts with the rest of the fatty acid to form a bipolar molecule which is the soap. During the reaction, the solution becomes cloudy but with time, it again goes back to solution. The cloudyness appears because oil isn't soluble in water based solutions and the base is actually made solution in water.

Here the sodium hydroxide reacts with oil to form water and the soap molecule which is a chemical change.

What controls the development of cells and tissues in multicellular organisms

V125BC [204]

Answer:

Development is largely under the control of genes. Mature cell types of the body, like neurons and liver cells, express different sets of genes, which give them their unique properties and functions.
