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.

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 drought decreases the water level in Lake Winnipeg. The carrying capacity of the lake decreases.
Limiting factor?
Explain
Answer:
Water, fish
Explanation:
The limiting factors are the water of course and the organisms living in the lake.
A drought decreases the water level in Lake Winnipeg and the carrying capacity of the lake decreases. This is because it is:
Density IndependentWhen something is said to be density Independent with respect to ecology, it means that an external force is able to influence the volume of a habitat, notwithstanding the density.
As a result of this, this particular principle is in place here as a drought which is an external factor is able to affect the size of the water.

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.

d) During Transcription, a nucleotide has been deleted. Explain the effect this will have
on DNA as well as what happens in each step along the way to a protein.
Answer:
this mutation may change the open reading frame of the resulting RNA sequence and its final product, which is a protein in the case that this gene is used to synthesize a messenger RNA (mRNA) sequence
Explanation:
During the transcription, a region of DNA named 'gene' is used as template to produce an RNA molecule, typically a primary transcript of mRNA (pre-mRNA). Subsequently, this pre-mRNA suffers a process named RNA processing in order to generate a mature mRNA which is finally used to create a protein by a process called translation. If a deletion occurs during transcription, it may change the open reading frame (ORF) of the resulting mRNA when the mutation occurs in an exon of the protein-coding gene (i.e., occurs a frameshift mutation), while this deletion may not have any effect if it is localized within the introns which are removed during RNA processing. A frameshift mutation will change the amino acids that are added to the nascent polypeptide chain during translation.

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.
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.

How might green spaces help reduce the negative impact that humans have on Earth’s water supply?
It would give nature a place to fight back, and become more healthy, and less hindered. Cities mess up the evaporation cycle, and because of parks, the water is able to be soaked up by grass, and then released through evaporation. When it rains over a city, the water goes into gutters, and becomes more polluted.
