Answer: microevolution.

Explanation:

Allele frequencies in a population may change due to gene flow, genetic drift, natural selection and mutation

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.

Explanation:

The development of nervous system and sense organs in multicellular organisms has led to evolution of species in a more complex manner.

• 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.

Answer:

150.

Explanation:

On edge

The electric potential, to the nearest whole number is 150 V.

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.

Answer:

Sue has Parkinson's disease. She takes medication that increases the level of dopamine.

Explanation:

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.

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.

Answer:

Ecology is the study of all organisms in an environment

Environmental science is the study of the interrelatedness of everything in that environment

Explanation:

Answer Internal and external environmental factors, like gender and temperature, influence gene expression. ... Similarly, drugs, chemicals, temperature, and light are among the external environmental factors that can determine which genes are turned on and off, thereby influencing the way an organism develops and functions.

Explanation:

proportion : 12/70 = 35/x

70(35)=12x

2450=12x

204.166667=x and round it to make it 204.

The best estimate of the number of fish in the pond is 204. Thus, option D is correct.

Calculation:

70(35)=12x

2450=12x

204.166667=x and round it to make it 204.

Average speed has been defined as the total distance travelled in total time taken it means that we can calculate the average speed obtained by an object .

Mathematically,

Average Speed = Total distance travelled/Total time taken

It's S.I unit is meter/second

Average speed is a scalar quantity it means that it has only magnitude not direction.

Ecosystem has been the branch of science that deals with the study of relationship between living organisms and natural phenomena. Ecosystem has the system in which both living as well as nonliving organisms are present in a particular location.

Explanation:

Answer:

eukaryotic, because our body cells have nucleus and membrane-bound organelles

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'.

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.

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.
