e.
a fox consuming a rabbit
Explanation:a peacock spreading and shaking his feathers to attract a female
A peacock spreading and shaking his feathers to attract a female represents an activity within a population. So, the correct option is (D).
What is Population?
Population is the number of people in a single area, be it a city or town, region, country, continent or the world. A population is any complete group that has at least one characteristic in common. They are not just people.
It may consist of, but is not limited to, people, animals, businesses, buildings, motor vehicles, farms, objects or events. It is an average calculated from an entire group, distribution, or population that is obtained by dividing the sum of all population variables by the total number of variables in the population.
Here μ is the population mean. ∑X is the sum of all the observations in the space.
Thus, a peacock spreading and shaking his feathers to attract a female represents an activity within a population. So, the correct option is (D).

Which mRNA modification is likely absent if the mRNA is degrading prematurely from the 5 end of the mRNA?1) splicing together of exons.2) addition of the 3' polyadenylated tail.3) addition of the 7-methylguanosine cap to the 5 end.4) RNA editing.5) removal of introns.
Answer:
3) addition of the 7-methylguanosine cap to the 5 end
Explanation:
The 7-methylguanosine (m7G) cap is a modified methylated version of the Guanosine (G) nucleotide which is located on the 5′-terminus of the eukaryotic messenger RNA (mRNA). The m7G cap plays a key role in mRNA translation in eukaryotic organisms, from yeasts to mammals. During mRNA processing, m7G cap is added at the 5' end in order to protect mRNA from degradation by nuclease enzymes. Moreover, this cap also enables the proper attachment of the mRNA molecule to the ribosome during protein synthesis.
DNA and RNA are nucleic acids made up of long strands of 100's of nucleotides. What is the only difference in each nucleotide?
Answer:
Nucleic acid types differ in the structure of the sugar in their nucleotides–DNA contains 2'-deoxyribose while RNA contains ribose (where the only difference is the presence of a hydroxyl group).

Suppose that a mouse with black fur has both an allele for black fur and an allele for white fur (Bb). Based on this information, you can conclude that the dominant allele must be for fur andthe recessive allele must be for fur.
Answer:
Dominant black fur and recessive white fur
Explanation:
Black fur is showing over white fur so it is a dominant trait and white is recessive
Answer:
The dominant must be for the black fur and the recessive must be for the white fur.
Explanation:
A variation of a gene, which will generate a certain phenotype, even in the existence of other alleles is known as a dominant allele. On the other hand, a version of a gene that needs to be when inherited in order to be articulated in the phenotype is known as a recessive allele. The offspring will not express the phenotype of the recessive allele if it is inherited together with a dominant allele, that is, the phenotype of the dominant allele will just be expressed.True or false

Which of the following molecules directly participates in the process of translation?
Which of the following molecules directly participates in the process of translation?
mRNA, DNA, and rRNA
mRNA, tRNA, DNA, and rRNA
mRNA, tRNA, and rRNA
mRNA, tRNA, and DNA
Answer:
mRNA, tRNA, and rRNA
Explanation:
Translation is the second process of gene expression involving the synthesis of proteins from mRNA strand in the ribosomes. mRNA is the template for the translation process to occur. However, other certain molecules are necessary for the occurrence of translation.
The molecules that directly participates in the process of translation include:
- mRNA, which is transported from the nucleus into the cytoplasm (ribosomes) to be read.
- tRNA, this is a type of RNA present in the ribosomes whose function is to read the codons of the mRNA and carry corresponding amino acids to the peptide chain.
- rRNA, is another type of RNA that makes up the ribosomes and functions in the synthesis of proteins from the amino acids.
mRNA, tRNA, and rRNA directly participate in the process of translation.
During gene transcription, a specific sequence of DNA called gene is utilized as a template to create a messenger RNA (mRNA).This mRNA then travels to the ribosomes where is used to create a protein by a process called translation.The ribosome is a ribonucleoprotein complex consisting of proteins and ribosomal RNA (rRNA) sequences.The triplets of nucleotides or 'codons' in the mRNA indicate the linear order of amino acids that will be added to the protein.The transfer RNAs (tRNAs) are molecules that transport specific amino acids to the ribosomes and pair them via anticodon sequences that match the codon in the mRNA.In conclusion, mRNA, tRNA, and rRNA directly participate in the process of translation.

The synthesis of cholesterol is a process that involves over 30 different steps. Which step is the rate-determining step of cholesterol synthesis?1) The conversion of mevalonic acid to isopentenyl pyrophosphate2) The conversion of squalene into squalene 2,3-epoxide by squalene monooxygenase.3) The condensation of two acetyl-CoA molecules to acetoacetyl-CoA by thiolase.4) The conversion of HMG-CoA to mevalonate by HMG-CoA reductase.
Answer:
The conversion of HMG-CoA to mevalonate by HMG-CoA reductase
Explanation:
Cholesterol is one of the steroids found in the cell membranes of the eukaryotes, mainly in animal cells. It has a long fatty acid chain that is derived from the acetyl CoA. Biosynthesis of cholesterol includes four steps. The first step is the condensation reaction that forms mevalonate from the three acetate residues. The mevalonate is a six-carbon substance. It is followed by the formation of the isoprene units from the mevalonate.
The first step of the cholesterol biosynthesis that forms mevalonate from the acetate is a rate-limiting step. First, two molecules of acetyl CoA react to form acetoacetyl-CoA. It is followed by the joining of the third acetyl CoA to form HMG-CoA, a compound with six carbon atoms. The synthesis of the HMG-CoA from acetoacetyl-CoA is catalyzed by the HMG-CoA synthase. The HMG-CoA is then reduced into mevalonate, a reaction catalyzed by HMG-CoA reductase. Here, two molecules of NADPH serve as electron donors.
The pathway of cholesterol biosynthesis is regulated by the concentration of the cholesterol present in the cell and the pancreatic hormones. Accordingly, the expression of the gene encoding HMG-CoA reductase is regulated to determine the rate of the pathway, making this step a rate-determining step.
HMG-CoA reductase is present in two alternative forms: the phosphorylated form is the inactive form while the dephosphorylated form is the active form of the enzyme.
When the cholesterol levels are high, the hormone glucagon triggers the inactive of the enzyme by its phosphorylation. This covalent modification is reversible and the enzyme is dephosphorylated under the influence of hormone insulin when the intracellular cholesterol levels are low. In this way, covalent modification of the enzyme HMG-CoA reductase regulates the cholesterol biosynthesis.

Which medium grain sized metamorphic rock is composed mostly of the same mineral as the sedimentary rock limestone?
Answer:
Explanation:
Marble
Calcite-containing dolostone has undergone a metamorphosis to become marble (or dolomite), white marble develops when the limestone is pure.
What is a metamorphic rock?Calcite or dolomite recrystallization often results in bigger interconnecting crystals. Despite having a similar appearance to quartz, marble and quartzite are more softer than quartz.
By changing limestone under heat and pressure, marble is a metamorphic rock. As interlocking grains expand, the calcite in the limestone changes, and the original limestone's layers and fossils vanish.
Therefore, marble, when limestone, a sedimentary rock, is buried for millions of years under great pressure and heat, marble, a metamorphic rock, can be created.
