If you have a 20% sugar solution and a 45% sugar solution how does the 20%
solution compare to the 45% solution?
Answer:
It is 25% less
Explanation:
That is all i can say
A close comparison of the 20% solution to the 45% solution shows that the 20% solution is actually less than 50% of the 45% solution.
Arithmetically, you discover that the 20% solution is 25% or 0.25 (45% - 20%) less than the 45% solution.Comparatively, you can compute that the 20% solution actually represents 44.4% or 0.444 of the 45% solution (20% x 45%). The same result can be obtained by first dividing 20% by 45% and then multiplying the resulting dividend by 100.Thus, the result of the comparison shows that there is more sugar in the 45% solution than there is in the 20% sugar solution.

why do all organisms share the same genetic code?
Answer:
DNA is considered a universal genetic code because every known living organism has genes made of DNA. ... All organisms also use DNA to transcribe RNA, and then they translate that RNA into proteins. Every living organism uses that same system. Basically, every three pieces of DNA becomes one amino acid.

Explain (in one or two lines) the function of the followings:
(a) Promoter
(b) tRNA
(c) Exons
Answer:
In genetics, a promoter is a sequence of DNA to which proteins bind that initiate transcription of a single RNA from the DNA downstream of it. This RNA may encode a protein, or can have a function in and of itself, such as tRNA, mRNA, or rRNA. Transfer ribonucleic acid (tRNA) is a type of RNA molecule that helps decode a messenger RNA (mRNA) sequence into a protein. tRNAs function at specific sites in the ribosome during translation, which is a process that synthesizes a protein from an mRNA molecule. Proteins are built from smaller units called. An exon is the portion of a gene that codes for amino acids. In the cells of plants and animals, most gene sequences are broken up by one or more DNA sequences called introns.
A focus of environmental science not studied in ecology is the
Answer:
The influence of human activities on the environment
Explanation:
Anthropogenic activities may have negative effects on the environment by declining its biodiversity and by reducing natural resources. Human activities affect the environment through the use of fossil fuels (greenhouse gases), by contributing to the pollution of extensive areas, by overpopulation, eutrophication, deforestation, etc. The most significant effects of anthropogenic activities include the loss of biodiversity, climate change (global warming), habitat fragmentation, environmental degradation (e.g., ocean acidification), the introduction of invasive species, species extinction, etc.

Punnett squares are used to predict the most likely allele combination of a genetic combination.
Punnett squares are used to predict all possible allele combinations of a genetic combination.
Punnett squares are used to predict dominant allele combinations of a genetic combination.
Punnett squares are used to predict recessive allele combinations of a genetic combination.
Answer:
Punnett squares are used to predict all possible allele combinations of a genetic combination
Explanation:
The person above is right
Punnett squares are used to predict all possible allele combination of a genetic combination. Therefore, option (B) is correct.
What is a punnett square?The Punnett square is a diagram in the form of a square that is utilized for the purpose of predicting the genotypes that will result from a specific cross or breeding experiment. Reginald C. Punnett, who came up with the method in 1905, is honored with the naming of this technique. The diagram is utilized by biologists so that they can calculate the likelihood of a future generation inheriting a particular genotype.
A Punnett Square is a useful tool that helps to predict the variations and probabilities that can result from cross breeding. This can be done by comparing the offspring of two different species. This includes the estimation of the likelihood of sexually reproducing humans, animals, and plants.

O crystal size
O crystal structure
Answer:
It's crystal size.
Explanation:
The magma in the earth isn't cooling yet, the slower the cooling, the larger the crystals,
Pls, mark brainliest
From the given information the crystal size can be determined. The crystal size can be studies from the crystallization and cooling rate of magma.
What are minerals?Minerals are inorganic solids that exist in nature and have a distinct chemical composition and crystalline structure. Even though thousands of minerals in the earth have been found, only ten minerals such as quartz, orthoclase, pyroxene, calcite, biotite, garnet, clay etc. make up the majority of the crust's volume.
Mineral rock have to property of lustering such as polished metals and they reflect the light in color. The color of the powder of the crystalline mineral is called streak.
As the magma cools, the size of crystal becomes large. It is proved that from the cooling rate of magma, the crystallization and crystal size can be determined.
Hence, crystal size can be determined from the given information and option C is correct.

The development of nervous system and sense organs in multicellular organisms has led to evolution of species in a more complex manner.
Complexity of multicellular organisms• The development of nervous system and sense organs has permitted for a greater level of perception and better equipped organisms.
• It has permitted the organisms to collect resources, react to their surroundings, and take advantage of their surroundings.
• This has resulted in the organisms to survive longer and accommodate into bigger types of body.
• Such amendments has thus permitted organisms to become more complex and move up the food chain.
Thus, the development of nervous system and sense organs is associated with increasing complexity of multicellular animals.
