Answers

Answer:

One example is competition for limited food among members of a population. Density-independent factors affect per capita growth rate independent of population density. Examples include natural disasters like forest fires.

Decomposers such as bacteria feed on dead plants and animals. In which cycle does this decomposition play a role in forming the fossil fuels that people use for energy?

Answers

Answer:

The correct answer would be the carbon cycle.

Fossil fuels, decomposers, plants, and animals are all parts of the carbon cycle.

Decomposers breakdown the dead animals and plants into simpler compounds and help in returning the nutrients back to the environment.

These dead and decayed animals and plants, when buried for millions of years, get converted into fossil fuels due to high temperature and pressure.

Fossil fuels like coal, petrol et cetera release carbon into the atmosphere in the form of carbon dioxide when they are oxidized in automobiles and factories.

It is the carbon cycle

Which of the following will a bacterium produce when a human gene is added to its genome? Question 4 options:


human carbohydrates


a protein made up of both human and bacterial properties


the human protein coded for by the human gene


human plasmids that can be isolated from the bacterium

Answers

The correct answer is human protein coded for by the human gene.

Bacteria can not make difference between human and it's own genes. If a human gene is added to bacterial genome, bacterial mechanisms will translate it to protein according to nucleotide sequence in that particular gene. So, the product is going to be a human protein translated by bacterial machinery for the process of translation.

Answer:

the human protein coded for by the human gene
