A woman was born in 1916, but she just celebrated her 26th birthday in 2020. Explain how this is possible using just two words.
The year 1916 was a leap year which means she celebrates her birthday once every 4 years on another leap year. There have been 26 leap years since 1916.
What is a leap year?
It is a calendar year that contains an additional day added to keep the calendar year synchronized with the seasonal year. Each leap year has 366 days instead of 365, by extending February to 29 days rather than the common 28 days. These extra days occur in each year that is an integer multiple of 4.
Here woman was born on 29 February. The date 29 February comesw every four years. So in a century it would come 25 times and another time in the next four years.
Birth year : 1916
Current year : 2020
Difference : 104 years
Leap year comes every four years. So in 104 years it would come 26 years.
Hence assuming the woman in question was born on February 29th, that means she celebrates her birthday once every 4 years on another leap year.

Enzymes are proteins that are made up of amino acids that have peptide chain
An amino acid short chain is known as a peptide. Peptide bonds are the connections that hold the amino acids of a peptide together in a particular order. Peptides are typically recognized from proteins by their shorter length, though the exact number of amino acids required to distinguish between a peptide and a protein can vary.
Proteins called enzymes are made up of amino acids connected by one or more polypeptide chains. The fundamental structure of a polypeptide chain refers to this arrangement of amino acids. This in turn determines the enzyme's three-dimensional structure, including the active site's shape.

nitrogenous waste from protein metabolism is used to make urea which is subsequently secreted by the dct
Nitrogenous waste from protein metabolism is used to make urea which is subsequently secreted by the kidney.
What do you mean by protein metabolism?
Protein synthesis and breakdown (catabolism) are two different biochemical processes that are referred to collectively as protein metabolism. Transcription, translation, and post-translational modifications are the processes in the production of proteins.
What is kidney?In vertebrates, the kidneys are two reddish-brown, bean-shaped organs. They are around 12 centimeters (4+12 inches) in length in adult humans and are situated on the left and right sides of the retroperitoneal region. Blood enters them through the paired renal arteries, and it leaves through the paired renal veins. A ureter, a tube that transports expelled urine to the bladder, is connected to each kidney. The kidney takes involved in the regulation of toxin elimination, fluid osmolality, acid-base balance, various electrolyte concentrations, and volume of various body fluids. One-fifth of the blood volume that enters the kidneys is filtered in the glomerulus, where filtering takes place.
Thus from above conclusion we can say that nitrogenous waste from protein metabolism is used to make urea which is subsequently secreted by the kidney.

The derived trait which evolved to overcome the effect of gravity on animals moving on land is the evolution of stronger limbs with more muscle, which means that option C is the right answer.
Stronger limbs are very important for animals as they help in running, climbing, walking or paddle swimming. It also helps them in tearing flesh, and helps in balancing the weight of the body, which enables them to move smoothly. Animals without limbs are called invertebrate and they lack legs due to which they can just swim in water. Their movement is by crawling or sliding. The presence of limbs allowed the transition of life from aquatic to terrestrial. The anatomy of limbs also helps to identify relation with other animals which are present or extinct.

lipophilic weak bases that diffuse into the parietal cell canaliculi, where they become protonated
PPIs (proton pump inhibitors) efficiently prevent the release of stomach acid through binding to as well as impeding the hydrogen-potassium
Pantoprazole would be a weak, lipophilic base which thus arrives the acidified parietal cell arrangement through the parietal cell membrane and undergoes protonation. This produces the active metabolite sulfonamide, which also forms an irrecoverable covalent bond to two places of the H+/K+-ATPase enzyme upon the gastric parietal cells.
While both PPIs and acid controls decrease the quantity of stomach acid your stomach generates, H2 blockers act faster than PPIs and can provide comfort in as little and around 15 and 30 minutes.

How does the probability of an earthquake occurring evolve with time, in between two different earthquakes?.
The factors that determine the likelihood of an earthquake are history, strain accumulation, and the rate at which strain accumulates in a rock.
An earthquake occurs when two blocks of earth suddenly slip past each other. The fault or fault plane is the surface where they slip. Earthquakes are caused by sudden movement along fault lines within the Earth. The movement releases accumulated 'elastic strain' energy in the form of seismic waves, which travel through the Earth and cause the ground to shake.
Within the next 30 years, there is a 60% chance of an earthquake measuring magnitude 6.7, a 46% chance of an earthquake measuring magnitude 7, and a 31% chance of an earthquake measuring magnitude 7.5. A transform boundary causes a fault between two lithosphere plates, which slide past one another. This motion neither creates nor destroys crust and will result in earthquakes but no volcanoes.

How many bonds are there between adenine and thymine? and how many bones are there between cytosine and guanine?
Answer:
How many bonds are there between adenine and thymine?
2 hydrogen bonds
How many bones are there between cytosine and guanine?
three hydrogen bonds
Explanation:
There are two bonds between adenine and thymine. And there are three bonds between cytosine and guanine.
Nucleotides are small units used to construct DNA and RNA. Each nucleotide contains a nitrogenous base, a phosphate group, and a sugar group.
The five nitrogenous bases are adenine, guanine, cytosine, thymine, and uracil.
In DNA, the adenine bonds with thymine and the cytosine with guanine. Because these combinations only allow the formation of a hydrogen bond.
The hydrogen bond is formed only between the highly electronegative atom with hydrogen and the electronegative atom with a lone electron pair.
Between adenine and thymine, hydrogen bond formation occurs with the help of two donors and two acceptors.
