Which of the following data could best support the claim that species B arose from a speciation event in Lake I?
Answer: B
Explanation:
DNA analysis shows fewer differences between species A and species B in Lake 1 than species B and the populations in Lake 2
Speciation is defined as the mechanism through which new species or organisms are created.
What is Speciation?Speciation is an evolutionary mechanism in which the population of certain organisms evolves and becomes distinct species. It is the phyletic evolution within a lineage or lineage. In the given image, the speciation of organisms A and B shows that the difference in the genetic sequence of species and Species B in Lake I were somewhat related. Species B showed many differences to the organisms of Lake II.
Thus, species A and species B in Lake I may have arisen due to speciation.

I'm so confused anybody can help?
Answer:
Photosynthesis vs Cellular Respiration
Uses water <=> Gives off water
Uses carbon dioxide <=> Gives off carbon dioxide
Makes Glucose <=> Breaks down glucose
Gives off oxygen <=> Uses oxygen
Occurs only in light <=> Occurs all the time; does not need light
Takes in light energy <=> Releases light energy stored in glucose
Explanation:
Photosynthesis and Cellular Respiration are both biological processes. One is the reverse of the other.
Photosynthesis is an anabolic process while cellular respiration is a catabolic process. It implies that photosynthesis synthesis food by capturing energy while cellular respiration breaks down food and releases energy for cellular activities.
The two processes are important to keep each other going.
Plants release oxygen which is a by-product of photosynthesis, and we breathe in oxygen so that our cells can carry out cellular respiration and generate ATP.
Photosynthesis uses light energy, carbon dioxide and gives off glucose, water, and oxygen as by-product while cellular respiration uses water and glucose, and gives off carbon dioxide, water and energy as by-products.
While photosynthesis occur in green plants in the presence of light, cellular respiration occurs at all times.

Which factors affect natural selection?
inheritance, isolation, adaptation
variation, overpopulation, adaptation
isolation, overpopulation, speciation
variation, inheritance, speciation
Natural selection is an evolutive force that favor beneficial alleles increasing their frequency. The correct option is C). variation, inheritance, speciation.
What is Natural Selection?
Natural selection is an evolutive force that selects beneficial alleles and increases their frequency in the population. It results from the interaction between the individuals' phenotype and the environment, which determines gene destiny in space and time.
Natural selection results in adaptation, meaning that it causes an increase in the aptitude phenotype.
Aptitude (or fitness) is the contribution of each genotype to the next generation. It is reflected by the phenotype that results in the survival, fertility, and capability of having a mate. It is a way of measuring the individual ability to leave fertile offspring. Aptitude must be significant to the natural selection act in its favor.
Natural selection can act favoring an allele or against it, according to how it affects the fitness of individuals.
In many cases adaptations, resulting from natural selection can be correlated to environmental factors or selective pressures applied by other organisms or habitats.
The selective agent is the environmental trait that determines the differential survival of the phenotypic classes. The environment influences the probability that each genotype passes its gametes to the next generation.
Natural selection also acts on variation caused by mutations. Let us remember that a mutation is a change or alteration in DNI sequences that introduce new variants.
Many of these are eliminated, but some of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection.
Hence, a mutation can cause variation. If this variation turns to be beneficial to the population and increases individuals' fitness, it is favored by natural selection.
New generations inherit these new variants increasing their frequency in the population.
According to the environment and the species distribution, these changes might lead to speciation.
The correct option is C) variation, inheritance, speciation

mineral appears to emit green and blue light in the dark.
use the drop-down menu to answer the question.
what property is the mineral in this image demonstrating?
a. magnetism
b. fluorescence
c. luster
d. streak
help me asap. pls.
When a particular wavelength of light, such as ultraviolet (UV) light, electron beams, or x-rays, are focused on a mineral, fluorescence takes place, hence option B is correct.
What is the property of minerals?Calcite, fluorite, and sodalite are among the more popular fluorescent minerals, however there are many more as well. When exposed to UV light, many gemstones, including diamonds, rubies, emeralds, amber, and opal, will glow.
This light stimulates the mineral's electrons, forcing them to momentarily move to a higher orbit.
Naturally, mine wastes and tailing heaps provide excellent locations for any mineral, including fluorescents.
Therefore, nearly everywhere that has a good assortment of white light minerals also has fluorescent minerals, hence option B is correct.

Given is a strand of DNA, fill in the corresponding RNA strand and find which amino acids that strand codes for.
Answer:
The correct answer would be -
RNA - AUG GGG CCU UAC UAA
Amino acid -methionine-glycine-proline-tyrosine -stop codon
Explanation:
In the process of protein synthesis, the first process is known as transcription which involves the transcribing the mRNA strand from the DNA strand in a complementary manner. In this manner, Adenine transcribes into uracil and cytosine transcribe into guanine similarly thymine into adenine and guanine into cytosine.
Then, DNA strand - T-A-C-C-C-C-G-G-A-A-T-G-A-T-T will change into AUG GGG CCU UAC UAA and every three codes represent a triplet codon that translates into an amino acid first code called start codon and normally code for methionine (AUG) and last code for stop and does not code any amino acid.
Then, the amino acid will be - methionine-glycine-proline-tyrosine -stop codon
