what is the overall purpose of photosynthesis
Answer:
The primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. For the most part, the planet’s living systems are powered by this process.
Explanation:
What are possible origins of Earth's surface and internal energy?
Answer:
The flow of heat from Earth's interior to the surface is estimated at 47±2 terawatts (TW) and comes from two main sources in roughly equal amounts: the radiogenic heat produced by the radioactive decay of isotopes in the mantle and crust, and the primordial heat left over from the formation of Earth.

A. Water breaks down a rock into smaller pieces with the same composition as the larger rock.
B. Water dissolves rock into a solution.
C. Water carries away pieces of rock.
D. Any break down of a rock is the same as physical weathering of rock by water.
Answer:
it should be C. If not, try D.
Explanation:
Physical weathering of rock by water happens when waters affects the shape of a rock in any sort of form, such as breaking it into small pieces, breaking off a large chunk or etc.
The statement describes the physical weathering of rock by water - A. Water breaks down a rock into smaller pieces with the same composition as the larger rock.
physical weatheringis the process that breaks rocks apart without changing their chemical composition.water can contribute to the physical weathering of the rocks by is one of the reasons that can lead to cracking of rock caused by the freezing and thawing of water.Thus, The statement describes the physical weathering of rock by water - A. Water breaks down a rock into smaller pieces with the same composition as the larger rock.

What will happen over time if a population of organisms from the same species is physically separated and can't reproduce with one another?
the two populations will become different species over time due to accumulated mutations occuring in both populations
The two populations will remain the same species even as mutations occur randomly in the different populations
Answer:
Explanation:
the two populations will become different species over time due to accumulated mutations occuring in both populations
The two populations will become different species over time due to accumulated mutations occuring in both populations. Thus, option A is correct.
What are species and population?Species has been defined as the group of the potentially interfertile organisms that can be produce the fertile descendence. Organisms of the same species could live in the different areas, while the organisms of the same population use to live in only a particular area.
A population has been known as the group of the individuals of the same species that use to live in the given area. The individuals of that given population may or may not cross in order to produce the fertile descendence. Organisms of the same species that can live in the different areas, and while the organisms of the same population live in only one area.
Ecosystem has a level of the organization in which the different communities of different organisms along with their related abiotic factors, that use to interact with each other. This is a level of organization smaller than a biosphere and a biome.
Thus, option A is correct.

Why are some areas in Europe seeing a partial solar eclipse while others are observing a total solar eclipse ?
Answer:
A solar eclipse occurs when moon, sun and earth aligned and such alignment coincides at a new moon. In this alignment moon is in the between sun and earth which causes shadow over the earth.
A partial solar eclipse occur when moon, sun and earth is not exactly aligned.
Explanation:
A solar eclipse occurs when moon, sun and earth aligned and such alignment coincides at a new moon. In this alignment moon is in the between sun and earth which causes shadow over the earth.
A partial solar eclipse occur when moon, sun and earth is not exactly aligned.
Because earth is round some parts of the world can observe complete solar eclipse while some parts of the world can observe partial solar eclipse and some parts of the world simply does not observe any solar eclipse because they are having a night during that time.

Which nucleotides can pair together? Select all that apply. adenine (A) & cytosine (C) cytosine (C) & guanine (G) cytosine (C) & thymine (T) adenine (A) & thymine (T) adenine (A) & guanine (G) thymine (T) & guanine (G)
The nucleotides which base pairs together in the DNA helix are adenine(A) to the thymine (T) and Cytosine(C) to the Guanine (G). A purine always base pairs against a pyrimidine.
What are nucleotides?Nucleotides are the monomeric units of the genetic material i.e., DNA present in the nucleus of cell. Nucleotides are made up of three components which include a nitrogenous base, a deoxyribose sugar in case of DNA or a ribose sugar in case of RNA, and a phosphate group moiety.
The nitrogenous bases are of two types on the basis of their structures: Purines and Pyrimidines. Purines are double-ring structures which contain an imidazole ring attached to a pyrimidine ring. This include Adenine and Guanine. Pyrimidines are single-membranous structures which are similar to pyridine. Pyrimidines include cytosine, thymine and uracil. In DNA, thymine is present whereas in RNA, uracil is present.
A purine always base pairs with a pyrimidine. In case of DNA, an adenine forms two hydrogen bonds to base pair with thymine and vice versa whereas guanine forms three hydrogen bonds while pairing with cytosine residues and vice versa.
