In recent scientific history, the classification of the protist kingdom has changed several times. They are now grouped to consider their development over time instead of simply by what they look like or how they move. Which statement best describes the reason for these classification changes?
A. Traditional scientists did not have enough information about protists to attempt to clasify them.
B. Originally, scientists drew inaccurate conclusions about the classification of protists based on flawed data.
C. Changes in classification of this kingdom are made each time modern scientists discover a new species of protists.
D. The classification of protists changes as scientists learn more about how these organisms are related to each other and to members of other kingdoms.
Answer:
D
Explanation:
The statement that best describes the reason for these classification changes is the classification of protists changes as scientists learn more about how these organisms are related to each other and to members of other kingdoms. The correct option is D.
What are the characters of the protist kingdom?All eukaryotes that are not fungi, animals, or plants are collectively referred to as protozoa. It is a tremendously diverse group of species as a result.
Beyond a rather straightforward organizational structure, the eukaryotes that make up this kingdom, Kingdom Protista, do not share many characteristics.
Therefore, the correct option is D. The classification of protists changes as scientists learn more about how these organisms are related to each other and to members of other kingdoms.

out line three advantage of presence of. membranes in cell organelles
Answer:
Membrane-bound organelles offer several advantages to eukaryotic cells. ... If these enzymes were released in the cytosol, they could chew up the cell's proteins, nucleic acids and lipids, leading to cell death. The membrane surrounding the lysosome keeps those digestive enzymes away from the rest of the cell
Explanation:
Answer:
Membrane-bound organelles offer several advantages to eukaryotic cells. First, cells can concentrate and isolate enzymes and reactants in a smaller volume, thereby increasing the rate and efficiency of chemical reactions.

many pathogenic bacteria species are bcoming resistant to antibiotics. explain how such adaptions can develop through the process of natrual selection
Answer:
Antibiotic resistance evolves naturally via natural selection through random mutation, but it could also be engineered by applying an evolutionary stress on a population. ... The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce.

B. a species of flower changing in shape, followed by a change in the beak shape in its preferred species of pollinator
C. the shell shape of a species of snail remaining unchanged for millennia until it changes to an entirely different shape
D, whale species gradually changing from land-dwelling mammals that walked on four legs to marine mammals without legs
Whale species gradually changing from land-dwelling mammals that walk on four legs to marine mammals without legs would be an example of an organism evolving through punctuated equilibrium. So, the correct option is (D).
What is Punctuated equilibrium?Punctuated equilibrium is defined as the theory that proposes that once a species appears in the fossil record, the population will be stable, showing little evolutionary change for most of its geological history, with little or no morphological change. The condition is called statis.
This balance is the idea that evolution is rapid rather than following the slow, but steady path Darwin suggested. Long periods of stagnation with little activity are interrupted by intermittent bursts of activity in the case of extinction or emergence of new species.
Thus, Whale species gradually changing from land-dwelling mammals that walk on four legs to marine mammals without legs would be an example of an organism evolving through punctuated equilibrium. So, the correct option is (D).

15. The model includes a wavy arrow to show light striking the thylakoids. Which
label for the wavy arrow would be MOST USEFUL for communicating the role of
light in photosynthesis?
a. Light is radiated from the chloroplast during the light-independent reactions.
b. Light energy is cycled within the thylakoid.
c. The chloroplast reflects the green wavelengths of light.
d. Light is the energy source for converting ADP to ATP, and NADP+ to NADPH.
Answer:
This question is incomplete as it lacks the model, however, it can be answered based on general understanding of photosynthetic process. The answer is;
d. Light is the energy source for converting ADP to ATP, and NADP+ to NADPH.
Explanation:
Light dependent reaction, which is the first stage of photosynthesis, occurs specifically in the THYLAKOID of the CHLOROPLAST where the photons of light is absorbed by chlorophyll molecules (photosynthetic pigment). The light energy that hits the chlorophyll makes it excited, hence, providing the energy to produce ATP from ADP and NADPH from NADP+.
These products are pivotal in the next stage of photosynthesis (light independent stage). Hence, light plays a very crucial role in photosynthesis and the most useful way for communicating the role is by saying it provides the energy source for converting ADP to ATP, and NADP+ to NADPH.
