Answer:
This voice box occurs in all amphibians but is anatomically most complex in frogs. The larynx exits into the trachea; the latter bifurcates into the bronchi and then into the lungs. The glottis then opens, and elastic recoil of the lungs forces the pulmonary air out and over the new air in the buccopharyngeal pocket.
Explanation:
Answer: b. classify all organisms into monophyletic groups.
Explanation:
The modern taxonomy is the study of classification of organisms which classified the organisms on the basis of ancestral relationships, reproduction, morphology and behavior to identify the living organisms on earth and group them together. This is the scientific basis for classifying the species.
The classification of organisms into monophyletic groups is one of the criteria for classification in modern taxonomy. In monophyletic group or clade is a group which includes the descendants that belongs to the common ancestor. The organisms of the group share derived characteristics like morphological similarities, mode of reproduction and similarities at the genomic level.
<h3><u>Answer and Explanation;</u></h3>
- <u>Endosymbiotic theory</u> explains the origin of chloroplasts and mitochondria and their double membrane. Mitochondria of eukaryotes evolved from aerobic bacteria living within their host cell and the chloroplasts of eukaryotes evolved from endosymbiotic cyanobacteria.
- On the other hand according to the <u>autogenous hypothesis, </u>mitochondria and chloroplasts have evolved within the protoeukaryote cell by compartmentalizing plasmids or vesicles of DNA within a pinched off invagination of the cell membrane.
- <u>Endosymbiont theory </u>is the theory that suggests that simple prokaryotic cells were engulfed by larger prokaryotes 1.5 billion years ago.
- <u>Autogenous theory</u> is a theory that was proposed as an alternative to endosymbiont theory. proposes that eukaryotic organelles formed by infolding of the plasma membrane.
- <u>Horizontal gene transfer theory</u> is an alternative to endosymbiont and autogenous theories for the origin of complex organelles in eukaryotes.
The amount of greenhouse effect on Earth is directly proportional to the concentration of greenhouse gases in the atmosphere. In this era of industrialization, although it may seem that it has greatly improved the global economy, it also downplays the importance of consistently upholding our role as a steward to Earth.
The most common types of human activities that continuously worsen the greenhouse effect are: burning of fossil fuels, agriculture, and industrial processes.
The burning of fossil fuels such as coal, oil, and gas emits carbon dioxide which accounts for approximately three-quarters of the warming impact caused by the greenhouse gas emissions. This is amplified significantly through deforestation.
Methane, which accounts for 14 percent, and nitrous oxide, which accounts for eight percent are one of the major greenhouse gas emissions on earth. This can be sourced out from livestock and rice fields and also fossil fuel extraction and organic waste decay in landfill sites.
Industrial processes would incept fluorinated gases which accounts for one percent of the warming effect of current human greenhouse gas emissions.
Although it may seem that the values are not that high, but it must also be taken into consideration the several or a superfluous number of industries all around the world that simultaneously worsens the already groveling site of the continuously deteriorating and exploited planet Earth.
