Answer: Hydrogen

Explanation:

The chemical composition of the sun in the number of particles can be described as 71% Hydrogen, 27% Helium, 1.2% Oxygen, and 0.6% Carbon. Regarding the chemical composition by mass, hydrogen represents 91.2%, 8.7% Helium and small amounts of Oxygen and Carbon.

The Sun is the central star of the solar system. All other bodies in the Solar System, such as planets, dwarf planets, asteroids, comets, and dust, as well as all satellites associated with these bodies, rotate around them. Sun energy in the form of sunlight is stored in glucose by living organisms through photosynthesis, a process on which, directly or indirectly, all living beings that inhabit our planet. The energy of the sun is also responsible for meteorological phenomena and the climate on Earth.

True or False. Animals vary tremendously in structure. Nevertheless, they can be categorized into a few basic body plans based o

NNADVOKAT [17]

Answer:

True

Explanation:

Animals can be categorized into 3 based on body symmetry

Those without any body symmetry (asymmetrical)
Those with bilateral body symmetry (bilateria)
Those with radial body symmetry (Radiata)

Animals can be categorized into 2 based on number of embryonic germ layer;

Those with two layers - endoderm and ectoderm (diplobastic)
Those with three layers - mesoderm in addition to ectoderm and endoderm (triploblastic)

Animals can be categorized based on presence/absence of body cavity or coelom;

No body cavity - acoelomates
False body cavity - pseudocoelomates
True body cavity - coelomates

Animals can be categorized into 2 based on characteristics of embryonic development;

Deuterostomes
Protosomes

To find the graphical solution when adding vectors, you can draw a(n) ____ from the starting point to the ending point.

ehidna [41]

Answer:

arrow (which creates the resultant vector)

Explanation:

When you use the graphing technique when adding vectors, you can use the head to tail method to draw the vectors. And from the starting point or the tail of the first vector you drew, you will draw an arrow touching heads with the head of the last vector drawn.

With that, you can use a ruler to measure the resultant vector's magnitude, and use a protractor to measure it's direction.

Below is an example:

Let:

V1 = Vector 1

V2 = Vector 2

R - resultant vector.

Explain the difference between renewable and nonrenewable resources and give an example of each.

Lelu [443]

Answer:

Nonrenewable Resources take longer to be replenished, reneweable resources are easily replenished and easily accessible.

Explanation:

If something is Nonrenewable; for example fossil fuels like coal, oil, and natural gas, then that means that the organic matter is limited and not going to grow or be created easily on Earth.

Renewable Resources are usually classified into five categories; Hydro, Solar, Wind, Biomass, and Geothermal. All of these resources are easily accesible and can be used as a natural energy source.

Hope this helped :)
