The cost of fossil fuel is the harm that is caused to the people by the burning of fossil fuels.

The fossil fuels takes thousand of years to form inside the earth and when they are burnt they release huge amount of harmful gases in the environment.

Hence, the cost of fossil fuel is the amount of pollutants released by the fossil fuels that effect the health of  people.

How did you determine the types of cell division for both phases depicted in your model? Explain your answer.
klasskru [66]

Answer:

Cell division is a process that makes our skin, tissues, muscles, sex cells etc. It is the building block of our body.

Explanation:

When parents cells ahs been divided into two or more than two daughter cells then it is called division of cells. The division of cells occur as a larger cell. When we talk about eukaryotic cells, these cells divided into two distinct types of the cells, the vegetative cells.

The daughter cells are the identical to the parents cells genetically. There are two types of division such as mitosis and meiosis. When parents cells divides in daughter cells and daughter cells divided further, this process called the cells cycle. The mitosis cell division occur interphase. Meiosis cell division occur in two phase meiosis I and meiosis II.

You are carefully examining a living organism. Which of the following should convince you that the organism is acoelomate?
matrenka [14]

Muscular activity of its digestive system distorts the body wall should convince you that the organism is acoelomate.

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

An animal that does not have body cavity refers to an acoelomate. It is in contrast with the eucoelomates which are the animals that have body cavity. The acoelomate will not have a cavity which is filled with fluid between the digestive tract and the body. Hence there will be a distortion of body wall by the muscular activity of the digestive system.  

Some of the examples of acoelomate  are Cnidaria,Porifera , Platyhelminthes, Placozoa ,Gnathostomulida.Nemertina and Mesozoa. The presence of pseudocoelom in which the body cavity will not be lined by the mesodermal cells are the Pseudocoelomate.

spayn [35]

Answer:

Endosymbiont theory was proposed by Lynn Margulis in 1967 which suggested the origin of Chloroplast and mitochondria in eukaryotic cells.

The theory suggested that chloroplast and mitochondria organelle originated by engulfing the cyanobacteria and proteobacteria by other prokaryotic bacteria.

This shows that Prokaryotes exhibit the following characters:

1. These were the first organisms on Earth

2. Lack membrane-bounded

3. Aerobic bacteria are these types of cells

Eukaryotes exhibit:

1. Have mitochondria

2. Includes organisms that carry out aerobic respiration

3. Can be a multicellular organism

4. Includes organisms that are photosynthetic

5. Might have chloroplasts
