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.

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.

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.

Answer:

The thermal energy will flow from the computer to the person.

Explanation :

Usually computer are such devices which converts electrical energy into thermal energy and then it gets transferred to the person. The energy flows from the higher amount to lower amount. In this case, computer is producing higher thermal energy than the person that’s the reason for the flow of energy from computer to the person.

The thermal energy will flow from the computer to the person.

The energy in a system that controls its temperature is referred to as thermal energy. Heat is the progression of nuclear power. The first law of thermodynamics explains how heat and work are transferred between systems.

Bubbling water on an oven is an illustration of nuclear power. When a substance's atoms and molecules vibrate at a faster rate as the temperature rises, thermal energy is produced.

Utilizing steam power produced by burning oil, coal, liquid natural gas (LNG), and other substances to rotate generators and generate electricity is the process of producing thermal power.

Answer:

In Aquarium C, the water level on the side with 30% solution of NaCl will be higher than the water level on the side with 5% solution.

Explanation:

The movements of molecules based on differences in concentrations of these molecules in different regions is explained by the phenomena of diffusion and osmosis.

Diffusion is the movement of moleculesmfrom regions of higher concentrationto regions of lower concentration until equilibrium concentration is attained.

Osmosis which is a special form of diffusion involving water molecules is the movement of water molecules in a solution across a semipermeable memebrane, from regions of high solvent concentration (low solute concentration) to regions low solvent concentration (high solute concentration) until equilibrium is attained.

A 30% solution of NaCl is more concentrated than a 5% solution of NaCl, therefore, water molecules will move across the semipermeable from the 5% solution to the 30% solution. This will result in a rise in the water level in the 30% solution.

Thus in Aquarium C, the water level on the side with 30% solution of NaCl will be higher than the water level on the side with 5% solution.
