Answer:
A star shines a lot in the night, its color is saturated, the stellar mass, and size.
Explanation:
A star brightens up during the night due to their temperature (extremely hot). Its energy comes from natural nuclear reactions going into the star. The color of the stars come in any hex code, but usually the bluest one is higher temperature while the red one is lowest. The stellar mass describes the mass of a star and includes a formula to do. Stars also come in different sizes so there isn't a consistency when looking at them.

Explanation:
Malaria is an infectious disease caused by a unicellular eukaryotic organism belonging to the genus Plasmodium. These eukaryotic organisms are transmitted from one person to another by the female Anopheles mosquito when it feeds on human blood. Within humans, the Plasmodium species destroy red blood cells. A chemical compound called quinine has been used in developing effective drugs against malaria. The relationship between Plasmodium and humans would be
Answer:
Parasitism.
Explanation:
Parasitism is the relationship that is present between Plasmodium and humans because one organism takes benefit from the other whereas the other get harmed by the other. In Plasmodium and humans relationship, human gets harmed from the mosquito by having malarial disease, while on the other hand, mosquito is benefitted by sucking of blood which is a food source for mosquitoes.
How do we turn fossil fuels into electricity?
Answer:
they generate heat, which is then used to make steam, which drives turbines that generate electricity.

We burn fossile fuel they produce heat and steamThat steam is used to drive turbineThen the driving turbine produces electricity.4. Ocean currents and waves sometimes deposit sand and dirt offshore, building up a new landform called a(n) Barrier island. Estuary. Marsh. Sea wall.
Answer:
Barrier island
Explanation:
Barrier islands represent a class of coastal landform composed of sand and sediments that forms parallel to the coast. These islands are constantly changing, being shaped by different factors which include water currents (ocean currents), erosion and waves. Some of the most important parameters that influence the length and width of barriers are tidal range (i.e., the height difference between high tide and low tide), wave energy (i.e., the energy restrained from oceanic waves), the amount of sediment supply and sea-level trends.
Answer:
barrier island
Explanation:
A barrier island is a coastal accident composed of sand and other sediments. It might be narrow, of low height, and parallel to the coasts, but separated from them. In general, barrier islands appear like chains that can be composed of a few or several islands. These chains might extend for many kilometers. Their formation depends on many oceanic factors, which can easily form them and then make them disappear, such as waves, tides, streams, and other physical factors of the ocean. They are significant because they protect the coasts and lands from erosion and the damage caused by the storms. Besides, the barrier islands usually provide habitat for many different species. Their shape is very dynamic. They form, get eroded, change position, change their size, disappear and appear again through time. An estuary is a region where freshwater mixes with seawater. These are unique ecosystems where many different species can live in. A marsh is a depressed area saturated and cover by water, where many aquatic plants grow. A sea wall is a structure that is placed on the coasts and that protects them from erosion, specifically, wave erosion. These structures are not separated from the land.how does a self feeder get food
Answer:
Autotrophs (self-feeders) are organisms that use an external energy source to assimilate inorganic resources from the environment and synthesize the biological molecules needed to sustain life. The ultimate source of this energy is the nuclear fusion of hydrogen in the Sun.

Which characteristics demonstrate that sea anemones are animals and not plants? Select two that apply.
A. The cells do not contain a membrane-bound nucleus; that is, they are prokaryotic.
B. The organism depends on other organisms for nutrition; that is, it is heterotrophic
C. The organism does not have cell walls, which are rigid structures that provide support and protection
D. The organism consists of cells that perform chemosynthesis
Answer:
it is a and d thanks and sorry if it's not correct
Characteristics demonstrate that sea anemones are animals and not plants are;
The cells do not contain a membrane-bound nucleus; that is, they are prokaryotic.The organism consists of cells that perform chemosynthesis.What are sea anemones?. They are soft-bodied, sedentary colourful flower-like animals. They are attached to the sea bed with the help of a fleshy foot.
.Thus, the move of sea anemones is restricted. They are good predators and catch prey with their tentacles. Sea anemones possess features of animals thus, cell wall is absent in their cells

3. Photosynthesis. Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.
what is the density to the nearest hundredths, of a metal with a volume of 3.00 cm3 and a mass of 8.13g?
The density to the nearest hundredths, of a metal with a volume of 3.00 cm³ and a mass of 8.13g is 2.71g/cm³. Details about density can be found below.
How to calculate density?The density of a substance is a measure of the mass of matter contained by a unit volume and it can be calculated by dividing the mass of the substance by its volume.
According to this question, a metal with a volume of 3.00 cm³ and a mass of 8.13g is given. The density of the metal can be calculated as follows:
Density = 8.13g ÷ 3cm³
Density = 2.71g/cm³
Therefore, the density to the nearest hundredths, of a metal with a volume of 3.00 cm³ and a mass of 8.13g is 2.71g/cm³.
