Answer:

Explanation: Choosing food from farmers that aim to conserve the natural resources and have as little impact on the land as possible. But even buying as much as you can from local farmers makes a different. Eating more whole grains, vegetables, fruits and nuts, and less red meats and processed foods does too. Grow your own fruits and vegetables.

What best describes a vestigial structure

timofeeve [1]

Answer:

Vestigiality is the retention during the process of evolution of genetically determined structures or attributes that have lost some or all of their ancestral function in a given species. Assessment of the vestigiality must generally rely on comparison with homologous features in related species

Carl Woese and collaborators identified two major branches of prokaryotic evolution. What was the basis for dividing prokaryotes

Natali [406]

Answer:

d) genetic characteristics such as ribosomal RNA sequences

Explanation:

Carl Woese and his collaborators identified two major branches of prokaryotic evolution which are bacteria and archaea. They used 16S rRNA sequencing to study the similarities and differences between archaea and bacteria.

After sequencing the complete genome structure of Methanococcus jannaschii in 1966 which is an archaea they concluded that bacteria are more closely related than humans than bacteria.

After many years Carl Woese gave the three-domain system which divides prokaryotes into archaea and bacteria according to differences in their rRNA sequencing. Eukarya was the third domain. So the correct answer is d.

Explanation:

The plant is utilizing CO2 in photosynthesis

Photosynthesis produces glucose and O2 from inorganic CO2, light energy and water.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Bromothymol blue, an acid indicator, goes from blue to yellow when reacting with acid. The color change in sunlight confirmed the use of CO2, dissolved within the solution as carbonic acid- its removal from the solution makes the more basic, and the solution goes from yellow (acidic) to blue (alkaline).

CO2 + H2O ↔ H2CO3

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released.

Occuring in several complex steps, photosynthesis is a rate limited reaction, it depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Additionally,

water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ions and produces molecules of the energy storage molecule ATP through an electron transport chain.
This occurs in the thykaloids, where pigment molecules like chlorophyll reside.
Later, in dark reactions, NADP and NADPH are used in the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules. These store energy in their bonds, which can be released in respiration in the mitochondria.

In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’s cycle via the oxidization of pyruvate( through the process of glycoysis). The electron transport chain, in which oxygen functions as the terminal electron acceptor occurs in both plants and animals.
