what would happen to the planet if all oxygen breathing organisms became extinct and only plants remained on the earth

Many plants depend on animals primarily insects for pollination and sexual reproduction. If the animals (insects that pollinate) most flowering plants would be unable to reproduce and would go extinct.

Both plants and animals undergo cellular respiration producing Carbon Dioxide. Animals produce only Carbon Dioxide while plants produce both Carbon Dioxide and Oxygen. If animals went extinct there would be less Carbon Dioxide to support photosynthesis and more complex plants would have a difficult time adapting to the reduced levels of Carbon Dioxide.

Plants that survived the extinction of animals would be much simpler than presently complex plants.

Perhaps some plants would become predators of other plants to absorb the nitrogen content of other plants because of the lack of animals to engage in the recycling of nitrogen content.

All organisms must perform life-sustaining metabolic processes in order to survive.

Alik [6]

Explanation:

Unicellular organisms or single celled organisms that are made up only of one cell. Hence the name.
Unicellular organisms are further divided into Prokaryotic and Eukaryotic organisms
Examples of prokaryotic organisms are bacteria and Eukaryotic are protozoa and unicellular algae, however many eukaryotes are multi cellular as well.
These organisms have to carry out life sustaining metabolic processes for their survival.
These processes are metabolism, homeostasis and reproduction. Metabolism is important as it involves conversion of food into energy for cellular processes. Homeostasis for maintaining a constant internal physical and chemical conditions and reproduction is by cell division.
Multi cellular organisms as the name says unlike unicellular organisms consists of more than one cells.
Examples of multi cellular organisms are animals, land plants etc.,
Metabolic process in multi cellular organisms is a broad category of processes happening for these organisms which involves chemical reactions and pathways that happen at organismal state, transporting substances between the cells.

Genetically engineered pork has a higher flesh-to-bone ratio. Which of the following sentences explains how pork is genetically

Oksanka [162]

The answer is A) the desired gene is inserted into the genomes of the pork.

The techniques of genetic engineering are used to introduce hybrid genes for some desired substance or protein or trait into other organisms. Here, the desired gene is inserted into pork's genome and as a result, it has a higher flesh-to-bone ratio.

- B) is not the right answer because it is not necessary to change all the genes in the pork genome or it will be transformed into totally different organism.

- C) is not the right answer because the pork does not have plasmids.

The ability of body systems to increase their function, given the need to adapt, is known as the The ability of body systems to

Whitepunk [10]

Answer:

The ability of body systems to increase their function, given the need to adapt, is known as the physiologic reserve.

Explanation:

The ability of body systems to increase their function if the need to adapt arises is known as a physiological reserve. Frequently, this term is used to refer to the operating limits of a particular physiological system when under stress. When this stress exceeds the ability of a particular organ or system to compensate for it, organ failure occurs. Adaptation achieves its highest efficiency when changes are generated gradually/progressively rather than abruptly. In aging, this reserve is diminished and therefore the ability of the organs to adapt to stress is lower, that is, the ability to adapt is reduced in extreme ages.
