PLEASE HELP!!!!!!!!What are the two stages of photosynthesis represented by B and C in the diagram shown?
Answers
B is representing photosystem 1, while C is representing photosystem 2
I could probably give a more confident answer if there were some labels or a key to describe the symbols given in the diagram. Hope this helps!
Final answer:
The two stages of photosynthesis represented by B and C are the light-dependent reactions and the Calvin cycle. In the light-dependent reactions, light energy is used to produce ATP and NADPH. These energy carriers are then used in the Calvin cycle to convert CO₂ into glucose.
Explanation:
The two stages of photosynthesis represented by B and C in the diagram are the light-dependent reactions and the Calvin cycle.
In the light-dependent reactions, chlorophyll absorbs light energy and uses it to produce ATP and NADPH. These energy-carrying molecules are then used in the Calvin cycle, which takes place in the stroma. In the Calvin cycle, carbon dioxide is converted into glucose using the energy stored in ATP and NADPH.

Answer:
B. Sympatric speciation, habitat differentiation.
Explanation:
The right answer to our question is B, Sympatric speciation, habitat differentiation.
Edward Bagnall Poulton derived the term sympatric speciation in 1904. It is a mode of speciation, which entails new species emerging from an ancestral species that is still alive and extant. Both the emerging and ancestral species will exist in the same zone.
This speciation is found more in plants. There are different types of these speciations. Habitat differentiation is seen within sympatric speciation. It is found when mutations that exist in the same zone can make use of varying conditions. Allopatric speciation and parapatric speciation are the other types of speciation.
Final answer:
In the given scenario, Sympatric speciation driven by habitat differentiation has occurred. The different 'habitats' are represented by the flower color preferences of the beetle variants, leading them to diverge to the point of becoming distinct species.
Explanation:
The type of speciation that has occurred in the provided scenario is Sympatric speciation, driven by habitat differentiation. In this context, sympatric speciation refers to the process where new species evolve from a single ancestral species while inhabiting the same geographic region. In this case, the 'geographic region' is the color of the flowers. The red and orange flowers represent different 'habitats' for the beetles.
In terms of what has driven this speciation, it is habitat differentiation. This is because even though the beetles are occupying the same general physical area, their 'habitat' in terms of the color of the flowers they prefer has caused a divergence in their mating and, hence, their gene pools. Over time, this leads to the two beetle variants becoming so different that interbreeding is no longer possible, effectively rendering them distinct species.

A biologist has found an organism she cannot identify while doing a census in a swamp. The best characteristic to look for in order to decide whether this organism should be classifies as a protist or as a plant is….
Answer: B) If it is unicellular, it is a protist.
Although there are single celled archaea and fungi.
I hope it helps, Regards.
Answer:
The organism is classified as protist or plant based on whether is single celled or multicellular and whether it makes its own food.
Explanation:
Both, protists and plants are eukaryotic meaning that these have nucleus in their cells and organelles bound by membrane. Unlike plants which may be multicellular, protists are single celled. Hence, a botanist must investigate to find if the cells are multicellular or not.
Another important feature is that if the botanists finds that the organism produces its own food, then it is a plant. As plants get their own food by combining the sunlight captured with carbon dioxide from the air through process called photosynthesis.

Cell division is how organisms grow.
What is Cell division?
Mitosis and meiosis are the two distinct processes of cell division. When people talk about "cell division," they typically mean mitosis, which is the process of creating new cells for the body.
The cell division process known as meiosis is what produces egg and sperm cells. A vital process for life is mitosis. A cell divides into two identical daughter cells after duplicating all of its components, including its chromosomes.
Due to the importance of this procedure, specific genes carefully regulate each phase of mitosis. Health issues like cancer may develop when mitosis is improperly controlled.
Therefore, Cell division is how organisms grow.
