Answer:
The gene that controls production of white blood cells.
Explanation:Gene expression within the body is controlled by the cells, which determine when a specific gene should or should not be expressed. Influenza (the flu) is caused by a virus that attacks the respiratory system
What is an example of behavioral isolation
Answer:
Behavioral isolation is demonstrated in species of finches. Their mating calls are distinct yet unique across species.
Explanation:
Mutations arising from errors within gene replication often accumulate within populations, becoming more stable. They may lead to the formation of separate, genetically distinct populations called species. These new species arise via:
allopatric speciationperipatric speciationparapatric speciationand sympatric speciationBehavioral isolation is an isolating mechanism that is part of sympatric speciation. Here, there are apparent non-physical barriers to prevent mating, and several related species live within a population and gene-flow. However, reproductive isolation occurs through assortative mating (mate choice based on shared traits) which may lead to heteropatric speciation.
Commonly observed in birds, it involves distinct and unique courtship and mating signals. Mates only respond to those fitting the required behavioral patterns such as a courtship dance, nest building, foraging and songs.

What would be the best control group for global warming? Select one: (A)laboratory simulation,(B )a computer simulation or (C) another identical earth that has not seen increases in greenhouse gases (even though this is not possible)
Answer:
C. another identical earth that has not seen increases in greenhouse gases
The best control group for global warming would be another identical earth that has not seen increases in greenhouse gases.
What do you mean by Global warming?Global warming may be defined as the gradual increase in the Earth's average temperature due to the trapping of greenhouse gases by the atmosphere.
The excessive release of greenhouse gases like methane, Carbon dioxide, nitrous oxide, and ozone are responsible for global warming. These gases are released by automobiles, industrial smoke, etc.
Deforestation is also considered the cause of global warming. Trees help in the reduction of carbon dioxide from the atmosphere and convert it into oxygen.
Therefore, the best control group for global warming would be another identical earth that has not seen increases in greenhouse gases.

Type 1 diabetes is caused by destruction of beta cells in the pancreas that produce insulin. Which of the following best explains why a person with this disease needs medication?
a. Medication is needed to act as a signaling molecule to activate the signal transduction pathway.
b. Medication is needed to allow alternate signaling transduction pathways to control glucose levels.
c. Medication is needed to open channels to allow signaling molecules to enter pancreatic cells.
d. Medication is needed to serve as second messengers to regulate glucose uptake by cells.
Answer:
the answer is a. Medication is needed to act as a signaling molecule to activate the signal transduction pathway.
i took the quiz
Medication is needed to act as a signaling molecule to activate the signal transduction pathway. So, the correct option is (A).
What is Type 1 Diabetes?Type 1 diabetes also called insulin-dependent or juvenile diabetes which is usually develops in children, adolescents, and young adults, but it can occur at any age. A condition in which the immune system destroys the insulin-producing cells in the pancreas. These are called beta cells.
There are several signs of type 1 Diabetes which include:
Extreme thirstIncreased hungerDry mouthUpset stomach and vomitingFrequent urinationWhen a person suffering from this disease needs medication which is need to act as signaling molecule to activate the signal transduction pathway. Type 1 Diabetes is characterized by a progressive loss of insulin-producing β-cells in the islets of the pancreas. Immune destruction of β-cells is partly mediated by high levels of pro-inflammatory cytokines.
Thus, medication is needed to act as a signaling molecule to activate the signal transduction pathway. So, the correct option is (A).

You want to know if black squirrels or brown squirrels have a greater birth rate. Your ALTERNATIVE hypothesis is:_________.
Answer:
Natural selection is a mechanism of evolution proposed by Charles Darwin. It is the differential survival and reproduction of individual due to the difference in the phenotype. Over time, this process results in populations which are better adapted to their environment as they tend to survive and produce new offspring. The brown squirrels with thick coat survive at a higher rate than the brown sqirrels without the thick coat. Thick coat is a adaptation for survival in cold winters which are chosen over the other and allowed to reproduce.

In a typical mammalian cell, what is the average percentage of total cell weight for protein and dna?
Answer:Protein is evaluated at ≈55% of the cell dry weight, followed by RNA at ≈20%, Lipid at ≈10% and DNA at ≈3% (the rest being polysaccharides, metabolites, ions etc.).
Explanation:
A typical mammalian cell averages 18% protein and 0.25% DNA by weight composition.
According to research, a typical mammalian cell is made up of water, ions, and macromolecules such as proteins, lipids, DNA, RNA, carbohydrates, and some miscellaneous metabolites.
The water component of a typical mammalian cell is about 70%, 18% proteins, 1% inorganic ions, 3% small metabolites, 5% lipids, 0.25% DNA, 1.1% RNA, and 2% polysaccharides.

Draw a flow chart that explains how DNA is used to create an organism. please use the words: DNA, gene, protein, cell, tissue, organ, organism.
Answer:
Please find the flowchart attached as an image
Explanation:
DNA is the genetic material contained in the cells of living organisms. The DNA contains a segment called GENE, which contains information used to produce useful products needed in the cell. The information contained in the gene is expressed to produce PROTEINS.
PROTEINS are responsible for many metabolic activities that occurs in a cell. The CELL functions due to activities of the proteins produced by gene expression. When similar cells come together, they form TISSUES. An aggregation of tissues performing similar functions form ORGAN. Organs functioning similarly come together to form ORGAN SYSTEM. A collection of organ systems in the body forms the ORGANISM.

The commercial fishing industry uses large nets to capture fish. Often these nets catch many species of organism that are not used by humans. What Change could lessen the negative effect to this practice for the commercial fishing industry?
A. Designing nets that release unwanted species without harming them.
B. Using the net in deeper regions of the ocean where different organisms live.
C. Decreasing the size of the nets, but using more of them.
D. Exploring new and uncharted areas of the ocean where the nets can be used.
Answer:
A. Designing nets that release unwanted species without harming them.
Explanation:
Over-fishing is a negative human practice that leads to the over-exploitation of aquatic ecosystems (i.e., both marine ecosystems and freshwater ecosystems). In an aquatic ecosystem, the communities of organisms coexist in a delicate balance where they are dependent on each other in the food web, providing stability to the whole ecosystem. Therefore, the over-exploitation of any aquatic species is expected to impact the whole ecosystem, thereby also having a negative impact on other fish populations.
Based on your knowledge of reproduction in bryophytes and ferns, is the presence of flagellated sperm in cycads surprising? Why or why not?
Answer:
The correct answer is - All plants share a similar life cycle
Explanation:
The sperms that the bryophytes are biflagellated whereas in ferns these are multi-flagellated that helps in the swimming to the archegonia or female part to perform the fertilization, due to the presence of water.
The sperms in cycads also have flagella for the same purpose of swimming in the pollen tube. The ferns and the bryophytes both require the same or similar life cycle that includes the flagella and water for the formation of the zygote.
