The picture shows a Single-celled organism that has a nucleus and organelles, lacks a cell wall, and obtains food by eating other organisms. The organism also has cilia that it uses to move through water. Which kingdom should this organism be classified?
Science
Protista
Protists are single-celled and usually move by cilia, flagella, or by amoeboid mechanisms. There is usually no cell wall, although some forms may have a cell wall. They have organelles including a nucleus and may have chloroplasts, so some will be green and others won't be. They are small, although many are big enough to be recognized in a dissecting microscope or even with a magnifying glass. Nutrients are acquired by photosynthesis, ingestion of other organisms, or both.

What is an ecosystem and what are its parts and functions?
What can challenge an ecosystem?
What are the roles of the water and food cycles in an ecosystem?
An ecosystem is a structural and functional unit of ecology where the living organisms interact with each other and the surrounding environment. In other words, an ecosystem is a chain of interactions between organisms and their environment.
Answer:
An ecosystem consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue.
Parts & Functions Of an Ecosystem
The functions of the ecosystem are as follows: It regulates the essential ecological processes, supports life systems and renders stability. It is also responsible for the cycling of nutrients between biotic and abiotic components. It maintains a balance among the various trophic levels in the ecosystem.
What are the major parts of an ecosystem? An ecosystem includes soil, atmosphere, heat and light from the sun, water and living organisms.
Challenges For An Ecosystem
Some of the primary challenges include, but are not limited to, habitat loss, climate change including sea level rise, and levee stability.
The Role and Function of Water
Water cycle have several impacts on the nature - it takes part in weather, erosion and watering plants.
In short term it is positive, to see green grass and trees, not just bonedry dead nature.
In longer term we can see weather changing, clouds made of tiny drops of water coming and leaving - changing humidity (important for fungi and liches), local temperature changes etc.
Longest takes erosion and it is mostly about changing soils structure and nutritients for plants. Erosion can be also seen on riverbeds - in soft rocks/soils being wider, in harder rocks narrow. Also sedimentation in delta is important for development of border ecosystems.
Water makes organisms live and rocks move, that is the importance of water cycle.

There were many factors that affected people who lived in the Great Plains during the Dust Bowl era. What was the main factor that drove people from the Great Plains?
Answer: The Dust Bowl was caused by several economic and agricultural factors, including federal land policies, changes in regional weather, farm economics and other cultural factors. After the Civil War, a series of federal land acts coaxed pioneers westward by incentivizing farming in the Great Plains.
Explanation:
1) Manifest Destiny: The US Government wanted settlers to move onto the Plains as they needed the land to be settled and farmed and for communities and towns to grow up and expand. This was needed if the USA was to be a rich and successful country. The government therefore promoted the idea of Manifest Destiny.
What evidence have you discovered to explain how cells are organized in the body, similar to the way dots in pointillism art is organized.
Answer:
I'd have to say that cells are grouped by function and specialty. Many of the same type of cell are joined in a common task. Muscle cells are joined to form a specific task. Different cells in the body form into different organs and structures to form the whole body.
In art, pointillism uses dots of various sizes and colors. These dots are arranged so as to produce a specific visual effect. The entire work is composed of many individual points to form the whole picture.
In this way, we can equate the body's various cell to dots in a work of pointillism.

Explanation:
Bacteria in the Shigella genus cause the disease shigellosis. The symptoms of shigellosis include diarrhea, fever, and intestinal cramping. The disease is unpleasant, but most people recover within a week. Shigellosis is transmitted from one person to another through bodily wastes. You can catch shigellosis from a baby when changing its diaper. People also catch the disease by drinking contaminated water. The best way to avoid shigellosis is through frequent hand-washing with soap.

How does the magma in underwater volcanoes in Hawaii form?
Answer:ike a blowtorch, the heat transforms deep rocks into oozy magma
Explanation:
Answer:
Like a blowtorch, the heat transforms deep rocks into oozy magma. The magma rises upward until it erupts onto the seafloor. When the sizzling lava (which is what magma is called when it erupts) hits the cooler water, it hardens into an underwater volcano, the heat transforms deep rocks into oozy magma

a two-paragraph report on flower reproduction
Answer:
Flowering plants reproduce sexually through a process called pollination. The flowers contain male sex organs called stamens and female sex organs called pistils. ... Cross-pollination happens when the wind or animals move pollen from one plant to fertilize the ovules on a different plant. The primary purpose of a flower is reproduction. Since the flowers are the reproductive organs of plant, they mediate the joining of the sperm, contained within pollen, to the ovules — contained in the ovary. Pollination is the movement of pollen from the anthers to the stigma.
Explanation:
Answer:
Alternation of generations occurs in plants, where the sporophyte phase is succeeded by the gametophyte phase. The life cycle of a flowering plant. The angiosperms were the last of the seed plant groups to evolve, appearing over 100 million years ago during the middle of the Age of Dinosaurs. Reproductive parts of the flower are the stamen and carpel. Often the carpel is referred to as the pistil, the female parts collectively termed the gynoecium. The androecium is the individual units of the androecium are the stamens, which consist of a filament that supports the anther.
Pollen Pollen grains, from the greek palynos for dust or pollen, contains the male gametophyte phase of the plant. The outer part of the pollen is the exine, which is composed of a complex polysaccharide, sporopollenin. Hypothesized steps in the evolution of the carpel. Nonvascular plants, the mosses, and liverworts have the gametophyte phase dominant. Vascular plants show a progression of increasing sporophyte dominance from the ferns and "fern allies" to angiosperms.

what is the difference between fraternal twins and identical twins in terms of gene reproduction?
Answer:
Fraternal twins are dizygotic and Identical twins are monozygotic.
Explanation:
Fraternal twins are dizygotic, meaning that they developed from two different eggs fertilized by two different sperms. Their genetic code is as similar (or dissimilar) as any other siblings. Identical twins are monozygotic, meaning that they developed from the same fertilized egg, and so have nearly identical genetic code.
