O
A. They are all unicellular.
O
B. They are all capable of photosynthesis.
C. They are all eukaryotes.
0 D. They are all primitive plants or animals.
Answers
Answer:
Kingdom Protista was first described by Antony van Leeuwenhoek in 1675. The kingdom includes the majority of unicellular and eukaryotic organisms.
Explanation:
Protists are eukaryotic organisms such that they consist of a well-defined nucleus, membrane-bound cell organelles, and are mostly unicellular. However, some of the protists such as algae perform photosynthesis, some protists exhibit mutualism, and some are parasitic.
Most of the protists are single cells, but they can exist in multicellular forms, in colonies, and can live as single-cell. Some of the examples include giant kelps, euglena, and diatoms.
Protists such as alga are capable of performing photosynthesis. Photosynthesis is the process of preparing food in the presence of sunlight, water, and carbon dioxide to yield oxygen and provide energy.
Protists are one of the diverse kingdoms in the classification of organisms as it comprises moulds, algae, and protozoa. Protists are not classified as plants, fungi, or animals. For example, the division Bryophyte is considered as a primitive division to plants, whereas kingdom Moneran is considered as most primitive.

Answers
Answer:
a long and wet winter but and short and drier summer. option one i think
Explanation:
Temperate rainforests are characterized by cooler; long wet season and short dry season.
The features of temperate rainforests:One of the world's major habitats is the temperate forest biome. These forests are characterized by humidity and high levels of precipitation. The temperate rainforests exhibit a broad array of temperatures, which correlate with the different seasons.
Temperature ranges from extremely cold in the winter and hot in the summer. The forests receive enough amounts of precipitation, generally between 20 to 60 inches of rainfall in a year. The temperate rainforests have a short dry season, while cooler and long wet seasons.
Thus, the correct statement is the first one, that is, cooler and long wet season and short dry season.

The cactus has a specialized fleshy stem that is specialized to store water for long periods of time. Which plant tissue most likely makes this action possible?
I know the answer is Ground, but i need to know WHY the answer is ground tissue. I WILL MARK BRAINLIEST
(on EDGE)
Answers
Answer:
If I were to guess its probably Vascular
Explanation:
Cactuses can store water nearly four months mainly in the winter and watering is not required for them frequently during that time. The stem acts as a reservoir for the amount of water it holds. The ground tissue of cactus has lots of parenchymal cells that store water.
What is parenchyma?The ground tissue system comes from a ground meristem which has three tissues, namely parenchyma, collenchyma, and sclerenchyma.
The ground tissue of cactus has many parenchyma cells that store water.
Thus, it can be concluded that the ground tissues helps cactus to store water for a long time.
