Answer:A
Explanation:
The statement provides the best explanation for the difference in biomass of organisms found at each trophic level is: organisms at higher trophic levels have less energy available to them than organisms at lower trophic levels.
WHAT IS TROPHIC LEVEL:Trophic level of an organism refers to the position of the organism in the flow of energy in an ecosystem. Organisms feed on one another in an ecosystem to obtain energy needed for their metabolic activities. More energy is contained in lower trophic levels than that of higher trophic levels. This means that, according to this question, more energy is in the producers than tertiary consumers.Therefore, the statement provides the best explanation for the difference in biomass of organisms found at each trophic level is: organisms at higher trophic levels have less energy available to them than organisms at lower trophic levels.

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.

O crystal size
O crystal structure
Answer:
It's crystal size.

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.

Answer:
- revealed that rRNA is highly conserved so can be used for classification
- have led to the development of a new taxonomic system divided into domains
Explanation:
The ribosomal RNA (rRNA) genes are widely used in evolutionary, phylogenetic, and phylogeographic studies as molecular markers because they represent nuclear genes that are highly conserved between species. However, it is important to highlight that rRNA genes form arrays at specific chromosomal sites, thereby they often exhibit pseudogenes that may interfere with their use as molecular markers (i.e., they produce multiple bands in the electrophoresis gel). In 1977, Carl Woese showed that Archaea is an evolutionary lineage separated from Bacteria by using molecular evidence based on an rRNA molecular marker (16S rRNA). Thus, Woese indicated that Eukarya, Bacteria and Archaea represent three different domains that arose separately from an evolutionary ancestor named 'progenote'.
A person’s will be the same on Jupiter and Earth. A person’s will be greater on Jupiter than on Earth.
Answer:
Greater on Jupiter
Explanation:
Gravity depends on mass. Jupiter has more mass than Earth so its gravity is two and a half times greater. Therefore a person will weigh more on Jupiter.
Answer:
A person will be greater on Jupiter than Earth. The surface gravity is having is larger than Earth’s by roughly 2.4 times. So, if you weigh 100 pounds on Earth it would be 240 on Jupiter. Hopefully this helps! Feel free to mark this as brainliest!

Leigh has collected data and performed statistical
tests for analysis. Describe the conclusions she can
draw about the data based on her analysis.
Answer:
She will obtain results to support -or reject- her working hypothesis. These results are subjected to statistical analyses in order to confirm that they are statistically significant
Explanation:
The scientific method is a rigorous process that consists of raising a working hypothesis, which is tested by experimentation or observational procedures and analysis of the results. The statistical analyses may have key roles during this procedure. In an experiment that involves statistical analyses, the results are subjected to statistical measures to evaluate the significance level and thus confirm (or reject) the statements made in the working hypothesis. The p-value is one of the most used statistical measures to determine if differences are due to randomness, or they are statistically significant.
Answer:
Because the calculated chi-square value of 5.19 is less than the critical value of 7.82, the null hypothesis can be supported. She is 95% confident that there is no significant variation in shell color along the beach coastline.

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.

Ecology is the study of all organisms in an environment
Environmental science is the study of the interrelatedness of everything in that environment

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.
true or false Geoengineering will have no negative effects on the environment.
It is false that geoengineering will have no negative effects on the environment.
What is geoengineering ?Geoengineering, also known as Climate Engineering, is the deliberate, extensive modification of the Earth's environment and climate in order to stop further climate change, halt and stop global warming, and lessen the effects on human society and the ecosystem.
Spraying compounds into the atmosphere to create reflecting aerosols and reflect sunlight into space is known as solar geoengineering. Although this would prevent global temperatures from rising, local or regional temperatures may still rise over the coming years, according to a recent study.
Hence, it is false that geoengineering will have no negative effects on the environment.

A 7.2 × 10–5 C charge has an electric potential energy of 1.08 × 10–2 J. The electric potential, to the nearest whole number, is V.
Answer:
150.
Explanation:
On edge
The electric potential, to the nearest whole number is 150 V.
What is the electric potential energy?The electric potential energy denoted by U is proportional to the charge and inversely proportional to the distance between the point where its is brought from infinity to the charge.
U = kQ₁Q₂/r
For identical charge,
U =kQ²/r................(1)
and the electric potential is given by
V = kQ /r................(2)
Dividing both the equations, we get
U/V = Q
Substitute charge Q = 7.2 × 10⁻⁵ C, Electric potential energy U = 1.08 × 10⁻² J, then the electric potential will be
V = 1.08 × 10⁻² / 7.2 × 10⁻⁵
V = 150 Volts
Thus, the electric potential is 150 Volts.
