Which of the following statements best describes the role of adenylyl cyclase in
the epinephrine signaling pathway?
A.It converts a polymer to its monomer subunits.
B.It moves substances across the plasma membrane.
ect!
C.It accelerates the production of a second messenger.
D.It transfers phosphate groups from to protein substrates.
Answer:
C.It accelerates the production of a second messenger.
Explanation:
Adenylyl cyclase is an enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic adenosine monophosphate (cAMP), a second messenger that activates the protein kinase A (PK-A) protein by dissociation of its regulatory subunit from the catalytic subunit. The first step of the epinephrine signaling pathway consists of the hormone binding to the epinephrine receptor localized on the cell surface. This binding activates a G protein inside the cell, which in turn activates the adenylyl cyclase enzyme. Subsequently, adenylyl cyclase converts ATP molecules into cAMP molecules. Since cAMP transports the message of the epinephrine hormone within the cell this molecule (cAMP) is considered to be a second messenger. Finally, cAMP activates the PK-A enzyme which phosphorylates different proteins and thus triggers different biological processes.
How can the expression of a single gene be quickly, efficiently, and specifically shut down at the transcriptional, posttranscriptional, and posttranslational stages through coordinated expression of a transcriptional repressor, an miRNA, and a ubiquitin ligase?
Answer:
Ubiquitin ligase is a protein enzyme recruits Ubiquitin-conjugating enzyme that come with the ubiquitin and catalyzes the transfer of ubiquitin to the protein substrate of interest and destructed by the proteosome.
miRNA are small RNA molecules with no coding behavior that binds with the mRNA with the help of base pairing of complementary codes. It helps in mRNA degradation and cutting of poly-A tail of mRNA type of gene expressing.
A gene-specific transcriptional repressor helps in preventing the transcription process of the mRNA by inhibiting the binding of the RNA polymerase to the promoter.
Where did all of the material come from that makes up the trees?
Answer:
Explanation:
The mass of a tree is primarily carbon. The carbon comes from carbon dioxide used during photosynthesis. During photosynthesis, plants convert the sun's energy into chemical energy which is captured within the bonds of carbon molecules built from atmospheric carbon dioxide and water.

Species in which dark brown fur (D) is dominant relative to light brown fur (d). Using the Punnett square below, predict the frequencies of the genotypes and phenotypes of the offspring from dark brown parents two who are heterozygous (Dd genotypes).
Answer:
Genotype frequencies25% DD
50% Dd
25% dd
or
1 DD: 2 Dd: 1 dd
Phenotype frequencies75% Dark brown, 25% light brown
or 3 dark brown: 1 light brown
Explanation:
Two heterozygous parents have the genotypes Dd. Therefore, the cross is Dd x Dd.
D d
D DD Dd
d Dd dd
25% (1:4) of the organisms have the genotype DD, and therefore the phenotype is dark brown, since it has two copies of the dark brown fur allele (DD)
50% (1:2) of the organisms have the genotype Dd, and therefore, the phenotype is dark brown since dark brown fur (D) is dominant to light brown fur (d).
25% (1:4) of the organisms have the genotype dd, and therefore the phenotype is light brown, since it has two copies of the light brown fur allele (DD)
Jake broke his fibula and had to wear a cast for six weeks. The muscles attaching to this bone atrophied (shrank) during this time. What muscle function would Jake be unable to perform well as a result?
Answer:
Explanation:
One of the functions of the muscle is the storage of amino acids which can be used for energy production when demands are high or for protein synthesis. But during muscle atrophy, this function becomes reduced which could lead to the particularly muscle been unable to stretch or contract due to weakness, it could also lead to the imbalance between protein synthesis and degradation.
Do cancer cells block nerve connections?
Answer:
Yes
Explanation:
Many different cancers can metastasize to the nervous system, but breast, lung, and skin cancers are the most common to do so.
Answer: Both interventions prompted cancer cells to recruit and nourish nearby blood vessels that, in turn, fueled their growth. Blocking the receptors prevented this growth. That study and others showed cancer cells were alert to signals from the nervous system.

Which two layers are part of the thermosphere?
exosphere and ionosphere
ionosphere and mesosphere
mesosphere and stratosphere
stratosphere and troposphere
Answer:
The exosphere and the ionosphere
According to the research, exosphere and ionosphere are two layers that are part of the thermosphere.
What is the thermosphere?It is one of the layers that make up the Earth's atmosphere characterized by X-rays, gamma and ultraviolet rays that cause sodium molecules and atoms to ionize, increasing the temperature.
Due to this peculiarity, the thermosphere includes the ionosphere, where ionization processes take place and the exosphere is the layer with the lowest density.
Therefore, we can conclude that according to the research, exosphere and ionosphere are two layers that are part of the thermosphere.

Accuracy in the translation of mRNA into the primary structure of a polypeptide depends on specificity in the ________.a) binding of ribosomes to mRNA.b) binding of the anticodon to small subunit of the ribosome.c) attachment of amino acids to rRNAs.d) binding of the anticodon to the codon and the attachment of amino acids to tRNAs.
Answer:
d) binding of the anticodon to the codon and the attachment of amino acids to tRNAs.
Explanation:
A transfer RNA (tRNA) is one of the three types of RNA molecules whose job is to match an mRNA codon( a sequence of three DNA or RNA nucleotides that corresponds to a specific amino acid) with the amino acid it codes for.
Each tRNA contains a set of three nucleotides called an anticodon which corresponds to the amino acid encoded by a codon of an mRNA. The amino acid encoded by the codon is also attached to the tRNA molecule. This ensures specificity and accuracy during translation.
Therefore, during the translation of mRNA into the primary structure of a polypeptide, accuracy depends on specificity in the binding of anticodon and attachment of amino acids to tRNA.
3. Three redwood trees are kept at different humidity levels inside a greenhouse for 12 weeks.
One tree is left outside in normal conditions. The heights of the trees are measured once a
week.
IV humidity levels
DV height
CG tree left outside
Answer:
This question is asking to identify the following:
Independent variable: Different humidity levels
Dependent variable: Height of the plant
Control group: Tree left outside in normal conditions
Controlled variable: same time of measurements (once in a week), same types of trees
Explanation:
Independent variable is the variable that the experimenter changes or manipulates in an experiment. In this experiment, three redwood trees are kept at different humidity levels. Hence, the independent variable is the DIFFERENT HUMIDITY LEVELS the redwood trees were kept at.
Dependent variable is the variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this case, the HEIGHTS of the trees measured is the dependent variable.
Controlled variable or constants are those variables that must be kept unchanged throughout the experiment for all groups. In this experiment, the constants are: same time of measurements (once in a week), same types of trees (redwood).
Control group is the the group in an experiment that does not receive experimental treatment. In this case, the group that does not receive treatment/control group is: Tree left outside in normal conditions.
In an old experiment, Jean Baptista van Helmont grew a plant in a pot
that he filled with 200 pounds of soil. After several years, the plant
grew to weigh 169 pounds. The amount of soil in the pot did not
change; it still weighed 200 pounds. Based on your knowledge of
photosynthesis, how did the plant gain most of its weight?
A. The plant gained weight by absorbing nutrients from the soil.
B. The plant gained weight by producing oxygen and storing it.
C. The plant used carbon dioxide to make organic compounds like
glucose, which increased the plant's weight.
D. The plant made carbon dioxide from organic compounds like
glucose, which increased the plant's weight.
Answer:
C. The plant used carbon dioxide to make organic compounds like glucose, which increased the plant's weight.
Explanation:
Plants are mostly autotrophic organisms i.e. have the ability to make their own food via the process of photosynthesis. The food, which s in the form of sugars makes up their biomass. Plants use carbon dioxide (CO2) in the presence of sunlight to make organic compounds such as glucose, which is necessary for growth.
Hence, according to this question, the plant in a pot filled with 200 pounds of soil gained weight and increased to 169 pounds because the plant used carbon dioxide in the process of photosynthesis to make organic compounds like glucose, which increased the plant's weight.

Explain the relationship and importance of different levels of organization in the human body e.g. the cell, tissue, organ, organ system
Answer:
All living and non-living things are made of one or more unique substances called elements, the smallest unit of which is the atom, (for example, the element oxygen (O) is made of O atoms, carbon (C) is made of C atoms and hydrogen (H) is made of H atoms. Atoms combine to form molecules. Molecules can be small (for example, O2, oxygen gas, which has 2 atoms of the element O; CO2, carbon dioxide, which has 1 atom of C and 2 of O), medium (for example, C6H12O6, glucose, which has 6 atoms of C, 12 of H, and 6 of O); or large (for example molecules called proteins are made of hundreds of atoms of C, H, and O with other elements such as nitrogen (N). Molecules are the building blocks to all structures in the human body.
