The protist known for forming plankton with a connection to the rise of plants is algae. Algae are autotrophic, perform photosynthesis, and vary from unicellular diatoms to multicellular seaweed and kelp.
Explanation:The protist that is most widely recognized for its role in forming plankton and is believed to have given rise to plants is a type of algae. Algae are plant-like protists that can be either unicellular, like diatoms, or multicellular, such as seaweed. These organisms are essential components of aquatic ecosystems and play a vital role in the food chain. They are autotrophs, meaning they produce their own food through the process of photosynthesis, using sunlight to convert carbon dioxide and water into sugars, much like land plants do. However, unlike land plants, algae don't have true stems, roots, or leaves.
Among the various types of algae, the chlorophytes (green algae) have been significant in the evolution of plants. Chlorophytes are diverse and primarily inhabit freshwater environments and plankton. They can range from simple, unicellular forms like Chlamydomonas, which has a pear-shaped morphology with flagella for movement, to the complex multicellular forms such as seaweed and kelp that form vast underwater 'forests'.
The major evolutionary episode corresponding most closely in time with the formation of pangaea was the _____.
A large tract of land is purchased by a commercial agricultural company. The land is cleared of its native flora, and a single crop is planted instead. What is the effect of this action?
Clearing land for a single crop in commercial agriculture can result in the loss of biodiversity, changes in rainfall patterns, and increased vulnerability to pests and diseases.
Explanation:When a large tract of land is purchased by a commercial agricultural company and cleared of its native flora to plant a single crop, it has several effects. One of the main effects is the loss of biodiversity as native plants and animals are displaced. This type of agricultural practice can also lead to changes in rainfall patterns and frequency and contribute to deforestation. Additionally, relying on a single crop can make the land more vulnerable to pests and diseases.

Bacitracin blocks the transport of nag and nam across the cytoplasmic membrane to the cell wall. like other antimicrobials that block cell wall synthesis, this would result in weak cell walls and __________.
Bacitracin inhibits the movement of peptidoglycan precursors, therefore interfering with cell wall synthesis and leading to weak cell walls. This results in bacterial cells being more susceptible to osmotic lysis, causing them to rupture due to a water concentration imbalance.
Explanation:Bacitracin is an antibiotic that inhibits the movement of peptidoglycan precursors from the cytoplasm to the cell wall, interfering with cell wall synthesis in bacteria. Consequently, this results in the creation of weak cell walls and renders the bacterial cells more susceptible to osmotic lysis. This condition refers to the rupture or disintegration of the cell due to an imbalance in water concentration through the cell membrane. Osmotic lysis may occur in bacteria if too much water moves into the cell, causing it to burst. Essentially, bacitracin creates an environment in which it is difficult for bacteria to maintain their cellular structure, hence aiding in their elimination.

(5.03 lc)the boxer crab, lybia tesselata, carries a small pair of anemones in its claws. when approached by a predator, it waves the anemones around, presenting the stinging tentacles and chasing away the predator. the anemones benefit by eating food particles from prey that the crab catches. what type of relationship is this?
Answer:
Mutualism
Explanation:
Mutualism is the symbiotic association between two organisms in which both the partners are benefited. In the given example, the boxer crab uses the stinging tentacles of anemone to protect itself from the predators. On the other hand, the anemone is benefited by feeding on the particles from the prey caught by crab. Since both crab and anemone are benefited, it is an example of mutualism.

Answer:
The answer is A i just took the test just Now.
Explanation:
Primary succession takes place over a long period of time on newly formed land, while secondary succession occurs quickly in areas that have disrupted by a natural disaster.
Primary succession takes place over a long period of time in an area that has been disrupted by a natural disaster, while secondary succession occurs quickly on newly formed land. The correct option is C.
What is Primary succession?Primary succession refers to the process of the gradual growth of plant and animal communities on newly formed or exposed land.
Option A is incorrect because primary succession takes place over a long period of time on bare, previously uninhabited land, while secondary succession occurs on land that has already supported life and has been disturbed by a natural or human-caused event.
Option C is correct because primary succession occurs over a long period of time in an area that has been disrupted by a natural disaster, such as a volcanic eruption or glacier retreat, and typically begins with the establishment of pioneer species such as lichens and mosses.
Thus, the correct option is C.
