Which is an example of an abiotic factor that would strongly affect thepopulation of water lilies in a pond?

Answers

Answer:

Sunlight

Explanation:

Abiotic means not alive, and the insects and fish options are alive, so we can eliminate those. Sunlight and rocks are left. Of these, the rock would not affect the water lilies, not as much as sunlight at least. Without sunlight, the water lilies would not be able to grow and thrive as all plants/flowers have sunlight as one of their basic needs, so sunlight must be the answer.

What are the two organelles are involved in cellular energetics ? Which of them are found in plants in animals?

Answers

The two organelles involved in cellular energetics are mitochondria and chloroplasts. While both organelles are involved in cellular energetics, they are only found in specific types of cells.

Mitochondria are found in both animal and plant cells, whereas chloroplasts are only found in plant cells. Organelles are specialized structures present inside cells that perform specific functions.

These functions can include metabolism, transport, and protection. Organelles are generally membrane-bound, meaning they are surrounded by a membrane that separates their internal components from the rest of the cell. Organelles work together in a coordinated fashion to maintain the overall health and function of the cell.

Cellular energetics refers to the processes by which cells obtain and utilize energy. This energy is used for a variety of functions, including movement, growth, and reproduction. The two organelles most closely associated with cellular energetics are mitochondria and chloroplasts.

chloroplasts  - found only in plants and algae. they convert solar radiation energy to chemical energy usable for the cell's metabolism.
mitochondria - found in both plants and animals, they produce energy (in the form of ATP - chemical compound) by decomposing sugars and fats. they use up oxygen to do it.

There are two species of freshwater shrimp that are introduced to a pond. The first species, Caridina cantonensis, is brightly colored with red and white stripes. The second species, Caridina multidentata, is more mottled drab in coloration. Fish have an easier time finding and eating Caridina cantonensis due to their bright colors. When each of these species reproduce they produce about 100 offspring, but only 30% Caridina cantonensis offspring survive to reproductive age, while 75% Caridina multidentata offspring survive to reproductive age. In this situation what is natural selection selecting for? In this situation what is natural selection selecting against? How do you predict this population will evolve? Identify how each of the listed conditions from the above scenario that influence natural selection.

Answers

Explanation:

Natural selection is the mechanism that is responsible for the evolution of organisms.  

In the given case, the Freshwater shrimp has been introduced to a pond in which the two species with variations are introduced.  

The C. cantonensis is brighter in color whereas the C. multidentata is mottled drab in color. The predator fish can feed easily on the species which is brighter therefore C. cantonensis is more susceptible. The mottled drab species is not easily predated by the species.  

The 30 % offsprings of C. cantonensis can survive till the reproductive age  whereas 75% of C. multidentata. This shows that natural selection has acted on the color of the shrimp species selected against the predator fish species.

The species with mottled drab color is the result of the differential reproductive rate.

Final answer:

Natural selection is favoring the Caridina multidentata species due to its mottled coloration providing protection against predators, and acting against the Caridina cantonensis species due to its conspicuous coloring. Higher survival rates to reproductive age in Caridina multidentata suggest that, over time, this species will increase in population assuming other environmental factors remain constant.

Explanation:

In the given scenario, natural selection is favoring the Caridina multidentata species. The mottled and drab coloration is providing higher survival rates by offering protection against predation. On the other hand, natural selection is acting against the Caridina cantonensis species which has bright colors that make it easily detectable by predators, leading to its lower survival rates.

The given conditions of coloration and survival rates to reproductive age influence natural selection. The higher survival to reproductive age in Caridina multidentata ensures the transmission of its color characteristics to a larger number of offspring. This leads to the prediction that over time, the population of Caridina multidentata will tend to increase compared to Caridina cantonensis, assuming all other environmental factors remain constant.
