Explain how and why natural selection has allowed species such as sharks and alligators to remain genetically stable for thousands of years.
Answer:
Stabilizing natural selection keeps gene frequencies constant in a population. The normal, most common traits are selected for and preserved so only a limited amount of evolution occurs and species can remain unchanged even over long periods of time.
Explanation:
A biological process called reproduction occurs when an organism creates young (offspring) of the same species.
What influence natural selection for survival of species?Gene frequencies in a population are maintained constant through stabilizing natural selection.
Because only a small amount of evolution takes place and the most typical, most prevalent features are preserved, species can persist unmodified even across very lengthy epochs.
It is among the most crucial traits shared by all living things. While not necessary for an individual's existence, reproduction is necessary for the survival of a whole species.
Therefore, natural selection has allowed species such as sharks and alligators to remain genetically stable for thousands of years.

A virus infects a lung cell and begins replication. The lung cell releases interferon into the extracellular environment where it can be picked up by other nearby cells. As a result, the other nearby cells slow down their protein-making machinery to slow down viral replication should they become infected. This is an example of what kind of communication
Answer: The options are not given but it is gotten from another websites and here are the options.
A.Cell-to-cell (membrane molecule) recognition
B. Cell junctions
C. Paracrine signaling
d. Synaptic signaling
The correct option is C.
Paracrine signaling.
Explanation:
This is because in paracrine signaling cell communicate with other near by cells through chemical Messengers. It is a form of cell to cell communication in which a cell produced signal and transfer it to other neighbouring cells whereby the neighbouring cells alter or change their behavior to counter the effect of the signal. From the question, the lung cells send signals to neighbouring cells and this alter their behavior by slowering down protein making machinery.

Dominique is a chemist and has just discovered a new drug that interferes with the Calvin Cycle of photosynthesis. They believe this drug is going to be awesome because it will allow the light reactions to run forever, while just stalling out the Calvin cycle. Terry disagrees, saying that any drug that stalls Calvin will ultimately inhibit the light reactions, too. Who is correct and why
Answer:
Terry is right.
Explanation:
Any drug that stalls Calvin will ultimately inhibit the light reactions because the Calvin cycle and light reactions are interconnected. The light reactions provide CO2 to the Calvin cycle while on the other hand, the Calvin cycle provides sugars to light reaction in order to produce ATP molecules from it so if Calvin cycle stops no sugar is provided to the light reaction for generating ATP molecules.

Which of the following is a characteristic of many eukaryotes?
a. Many eukaryotes have no DNA
b. Many eukaryotes have many cells
c. Many eukaryotes have no cell membrane
d. Many eukaryotes have DNA in cytoplasm
Answer:
c
Explanation:
The statement that represents a characteristic of many eukaryotes is that many eukaryotes have many cells. Thus, the correct option for this question is B.
What do you mean by Eukaryotes?Eukaryotes may be defined as the type of living organisms that significantly have a well-defined nucleus along with other membrane-bound cell organelles. These organisms have a complex level of compartmentalization.
According to the context of this question, almost all eukaryotes have DNA in their nucleus. This is because it is considered its genetic material. So, options A and D are eliminated.
The cell membrane is the characteristic feature of every eukaryote because this membrane separates the inner environment of the cell from external conditions. So, option C is eliminated as well.
Therefore, the statement that represents a characteristic of many eukaryotes is that many eukaryotes have many cells. Thus, the correct option for this question is B.

A plant species has two alleles for petal color: pink and white. The pink (A) allele is
dominant. If a true breeding pink flower is crossed with a carrier pink flower, what is the
probability in a percentage) that their offspring will be born as carriers for the white
flower trait? Use a Punnett Square to justify your answer
Answer:
There's no such thing as a carrier pink flower, as pink is a dominant trait. Only carrier white flowers are possible because white is recessive.

In real life, sequencing data is never as clean and clear as the sequencing data presented here. Typically, sequencing machines do not read eDNA sequences perfectly, occasionally mistaking a C for a T, for instance (though this is often <1% of the time). Additionally, there will even be some variability of the barcode among individuals of the same species! How can sequences without 100% identity to a reference still be useful for biodiversity assessment
Answer:
by using consensus sequences and complementing DNA barcoding data with other sources of information (e.g., morphological, and ecological data)
Explanation:
DNA barcoding refers to the taxonomic method used to identify and classify species by comparing DNA sequences. Some of the most used barcoding genes include the 16 subunit (16S) of the ribosomal RNA (rRNA) gene in prokaryotes, the Cytochrome c Oxidase I (COI) gene in animals, the Internal Transcribed Spacer (ITS) sequence in fungi and the RuBisCO gene in plants. A good gene for DNA barcoding purposes must exhibit intraspecific variability, conserved regions in order to synthesize appropriate PCR primers, and the sequence need to be short in length (100 to 1000 bases). The main problem associated with this identification method is the confidence value between genetic sequences. For example, when COI sequences are identical, there is a 6 percent of chance that these sequences belong to different species. On the other hand, the percentage of intraspecific variability among DNA barcoding sequences is variable, even among closely related species. This problem, as well as bioinformatic errors related to sequence reads, can be partially overcome by aligning genetic sequences (including outgroups) in order to obtain consensus sequences. Moreover, taxonomists reasonably argue that DNA barcoding data should be complemented with morphological and ecological data in order to achieve accurate species identification.
