The kingdoms that consist of both unicellular and multicellular organisms are the Protists and Fungi.
Kingdom may be defined as a type of taxonomic rank that is significantly composed of smaller groups called phyla. It is considered the second highest taxonomic rank, just below the domain.
Unicellular organisms are made up of only one cell while Multicellular organisms are made up of more than one cell. Protists and fungi are classified into eukaryotic cells which are complex and possess numerous cell organelles. Most of the protists are unicellular in nature such as Amoeba and Paramecium. Multicellular protists include diverse forms of algae and seaweed.
When it comes to fungi, most of them are multicellular such as mushrooms and molds. The unicellular forms of fungi are yeast.
Therefore, protists and fungi are the two kingdoms that consist of both unicellular and multicellular organisms.

Answer: Protists and fungi consists of this.
The answer is invasive species.
Invasive species are species that are not native to specific ecosystem, but they have a capability to spread widely through the ecosystem, This way they can threaten native species of the ecosystem or cause environmental harm.
After being introduced into the Black Sea, they greatly affect local ecosystem. In the new area, they have no natural predators and are able to spread. If they spread beyond the area they are introduced, they become invasive species which can overgrow native biotopes and are a great threat to the local biodiversity. This could lead to the extinction of some native species.

Currents and Marine Life
Currents are powerful physical forces in the seas. They move water and heat around the globe, and help determine the chemical make-up of the water column. Currents also are a major factor in ocean ecosystems. Two types of current motion, upwelling and downwelling, strongly influence the distribution and abundance of marine life.
Upwelling
Currents play a huge role in marine productivity, through a process called upwelling. Sea life is concentrated in the sunlit waters near the surface, but most organic matter is far below, in deep waters and on the sea floor. When currents upwell, or flow up to the surface from beneath, they sweep vital nutrients back to where they're needed most.
Nowhere is the link between ocean circulation and productivity more evident than around Antarctica. There, strong currents pump nitrogen and phosphate up from the deep sea to fuel vast blooms of algae and other plants. These plankton are eaten by swarms of shrimp-like crustaceans called krill. Because of upwelling nutrients, krill are abundant enough to feed the largest animals on earth, baleen whales, as well as myriad penguins, seals, and seabirds. In fact, despite the harsh conditions, the biomass of Antarctic krill is thought to be greater than that of any other animal on Earth.
Downwelling
The importance of upwelling to surface organisms is matched by the need of sea bottom life for downwelling, or the sinking of surface water. Surface water can be forced downward by the pressure of the “pile” of water that forms where currents converge or wind drives the sea against a coastline. But for bottom dwellers, the sinking of water caused by density changes is especially noteworthy. The global conveyer belt takes oxygen-rich surface water and flushes it through the deep sea. Without this renewal, the dissolved oxygen in bottom sediments and waters would quickly be used up by the decay of organic matter. Anaerobic bacteria would take over decomposition, leading to a build up of hydrogen sulfide. Few benthic animals would survive such toxic conditions.
In the most extreme cases, a lack of downwelling may lead to mass extinctions. Paleontologists have suggested that 250 million years ago, deep circulation slowed nearly to a stop, and the ocean began to stagnate. Low oxygen, sulfide and methane-rich waters filled the ocean deeps and then spread onto the continental shelves, wiping out 95% of all marine species in the greatest extinction event in Earth history.
Instructions: In this activity, you will explore the differences between upwelling and downwelling. Study the graphics and photographs illustrating upwelling and downwelling, then answer the questions about each process. Maps of the world’s major surface and deep currents are included as resources to help you understand where and how upwelling and downwelling occur.
The purpose of the Human Genome Project was to map out the complete sequence of human DNA, leading to a greater understanding of our genetic makeup and the potential genetic basis of diseases for medical advancements.
The main goal of the Human Genome Project was to determine and map out the complete sequence of DNA base pairs of the human genome. This refers to understanding the genetic makeup of the human species. By doing so, we could gain a better understanding of human evolution, genetics, and the potential for medical breakthroughs such as uncovering the genetic basis of diseases. Ultimately, the project aimed to boost our understanding and potential manipulation of human genetics to improve health and medicine.

The main goal of the Human Genome Project was to sequence the entire human genome, gain a better understanding of human chromosomes, and use the data for applied research on genetically related diseases.
The main goal of the Human Genome Project was to sequence the entire human genome, which is the complete collection of genes in an individual. By analyzing and mapping the DNA subunits and the location of each gene, researchers aimed to gain a better understanding of human chromosomes and genetic makeup. This project relied on basic research with both simple organisms and the human genome, with the ultimate goal of using the data for applied research like finding cures and early diagnoses for genetically related diseases.
