Answer:
New species develop when:
D. Diverging species no longer recognize one another as potential mates.
Explanation:
- The development of two or more new species from ancestral population is known as speciation.
- Speciation can occur when the population divides into groups and each group occupies a different habitat (geographic isolation) or when the members of the same population do not find one another as potential mate and do not interbreed (reproductive isolation mechanism).
- The three types are: Allopatric speciation.
Sympatric speciation.
Parapatric speciation.
- Allopatric speciation occurs when genetic divergence is allowed through geographic isolation.
- Sympatric speciation does not involve geographic isolation but involves reproductive isolation mechanisms.
- In Parapatric speciation, a population enters a new niche or habitat within the range of parent species and then evolution of reproductive isolation mechanism occurs.
Answer:
E. coli within the large intestine
Explanation:
A symbiotic relationship is known to be a relationship between two organisms. In this relationship, one organism may benefits and the other suffers[ Parasitism} or both organisms benefit [ mutualism], while one organism may benefit and the other neither benefits nor suffers[ commensalism].
Mutualism is an example of symbiotic relationship where the two organisms involve benefits.
In this case, Man benefit from the presence of E, coli in the large intestine because it keeps the digestive system healthy, help in the digestion of food and the production of vitamin K which helps in blood clotting. The E. coli also benefits because there is availability of nutrients that it needed.
Answer:
- ATP and NADPH facilitate the reduction of 6 molecules of 3-PGA (formed in carbon fixation)to six molecules of the simple sugar glyceraldehyde 3-phosphate (G3P).
- In the reduction process ADP and NADPH+ are made, when ATP releases energy and loses its terminal phosphate, and NADPH loses energy and a hydrogen atom.
- ADP and NADPH+ return to the light-dependent reactions for re-use.
Explanation:
Sugar biosynthesis in plants, called photosynthesis produces glucose from the reactants; it uses energy from sunlight, along with carbon dioxide and water. In chloroplasts, this occurs in the light-dependent and dark reactions. In the light- dependent reaction, solar energy stimulates photosystems, formed from pigments like chlorophylls.
In the light-independent reaction, products of the light reaction are used to make sugars. Here, in the Calvin cycle, the enzyme, RuBisCO, catalyzes the fixation of CO2 with Ribulose 1,5-bisphosphate (RuBP). Organic molecules are reduced and RuBP is regenerated.
Answer:
rain go brrrrrrrrrrrrrrrrrrrrrrrrrr
Explanation:
Think. use that noggin. Thunder means lightning, which is electricity, and water conductivity vs no conductivity in ice or snow, so not snow, hail, or sleet, meaning it is rain.
Water has conductivity because in snow and ice the ions responsible for creating a charge are not mobile like in water because they are frozen.
Answer:
high; low; energy.
Explanation:
Diffusion can be defined as the movement of gas molecules from a region of high concentration to a region of lower concentration until an equilibrium is attained or reached. This mixing of gas molecules in the liquid or gaseous state is due to their kinetic energy of random motion i.e without requiring bulk motion.
This ultimately implies that, diffusion is a phenomenon through which gas molecules in either a gaseous or liquid state spread out in response to a concentration gradient, which is simply the difference in concentration of the gases across a space.
During diffusion, molecules move from areas of high concentration to areas of low concentration. Also, diffusion does not require energy to move molecules.
In conclusion, increasing the surface area of a gas increases its collision rate and it's considered to be an evolutionary strategy that maximizes the diffusion of gas molecules because it catalyzes the rate of a gaseous reaction.
