In each of the following pairs, circle the species with the larger atomic radius:
(a) Mg or Ba
(b) S or S2-
(c) Cu+2 or Cu
(d) He or H-
(e) Na or CI
Answers
The atoms with the largest atomic radius are:
(a) Ba
(b) S
(c) Cu
(d) H-
(e) Na
Which atoms have the largest atomic radius?
(a) Ba has a larger atomic radius than Mg because Ba has more electron shells than Mg, even though they are in the same period.
(b) S has a larger atomic radius than S2- because S2- has gained two electrons, which increases the effective nuclear charge and decreases the atomic radius.
(c) Cu has a larger atomic radius than Cu+2 because Cu+2 has lost an electron, which decreases the shielding effect of the electrons and increases the effective nuclear charge, pulling the remaining electrons closer to the nucleus.
(d) H- has a larger atomic radius than He because H- has one more electron than He, and the additional electron adds another energy level to the atom, increasing its size.
(e) Na has a larger atomic radius than Cl because Na is a metal and Cl is a non-metal, and metals tend to have larger atomic radii than non-metals.

which of the following best describes the distribution of sodium and potassium in the body? sodium is primarily intracellular; potassium is primarily extracellular. sodium and potassium are primarily extracellular. sodium and potassium are primarily intracellular. sodium is primarily extracellular; potassium is primarily intracellular.
Answers
The correct answer is sodium is primarily extracellular and potassium is primarily intracellular.
While potassium is mostly intracellular, sodium is mostly extracellular. The primary fluid balance-maintaining minerals in the body are sodium, chloride, and potassium. Functions: Sodium, potassium, and chloride are minerals that support the body's fluid equilibrium, carry nerve signals, and contract muscles. These electrically charged minerals are referred to as electrolytes when they are dissolved in biological fluids including blood, urine, and the fluids inside and outside of our cells. Researchers discovered that the kidney regulates levels of sodium, potassium, and the waste product urea to save or release water. This may be the link between salt consumption and glucocorticoid levels.

Which nucleotide begins the first transesterification reaction? 2 x > N none of the above
Answers
The catabolite activated protein (CAP) in bacteria becomes inactive under **high glucose** and low lactose conditions. Activation of CAP requires **adenylate cyclase**.
CAP, also known as catabolite activator protein, is involved in regulating the transcription of various operons in response to changes in nutrient availability. When glucose levels are high, catabolite repression occurs, leading to the inactivation of CAP. This is because the presence of glucose decreases the level of cyclic AMP (cAMP) in the cell. CAP needs to bind to cAMP to become active, and this binding is facilitated by adenylate cyclase, an enzyme that catalyzes the conversion of ATP to cAMP. In low lactose conditions, the lac operon, responsible for lactose metabolism, is not induced, further promoting CAP inactivation. Overall, high glucose and low lactose conditions lead to CAP inactivity, thus preventing the transcription of certain operons in bacteria.

_______ pass(es) from the maternal blood to the fetal blood; while fetal _________ pass(es) the other way.
Answers
Nutrients and oxygen pass(es from the maternal blood to the fetal blood, while fetal waste products and carbon dioxide pass(es the other way.
During pregnancy, the placenta serves as the interface between the maternal and fetal circulatory systems. Through the placenta, certain substances are exchanged between the maternal and fetal bloodstreams.
1. Nutrients and oxygen: The mother's blood carries essential nutrients, such as glucose, amino acids, vitamins, and minerals, which pass from the maternal blood vessels in the placenta to the fetal blood vessels. Similarly, oxygen from the mother's blood diffuses across the placenta and enters the fetal bloodstream, providing necessary oxygen for the developing fetus.2. Waste products and carbon dioxide: The fetal bloodstream carries waste products, including carbon dioxide, produced by the growing fetus. These waste products diffuse across the placenta from the fetal blood vessels into the maternal blood vessels. The maternal blood then carries these waste products away from the placenta and out of the mother's body through elimination processes.This exchange of substances occurs through the process of passive diffusion and relies on concentration gradients and the difference in partial pressures of gases. The placenta acts as a barrier, allowing for the selective passage of substances while protecting the fetus from potential harm or exposure to certain harmful agents in the mother's bloodstream.
In summary, nutrients and oxygen pass from the maternal blood to the fetal blood through the placenta, ensuring the nourishment and oxygenation of the developing fetus. Conversely, waste products and carbon dioxide pass from the fetal blood to the maternal blood for elimination from the maternal body.

Eukaryotic cells have their chromosomes packaged in the ________. Eukaryotic cells have their chromosomes packaged in the ________. nucleus centriole nucleolus Golgi apparatus
Answers
Eukaryotic cells have their chromosomes packed in the nucleus.
Eukaryotic chromosomes are located inside the cell's nucleus. The principal function that distinguishes a eukaryotic cell from a prokaryotic cell is the presence of a membrane-bound nucleus. This nucleus is the “control center” of the cell that stores all of the cellular's genetic records, or DNA.
In eukaryotes, however, genetic material is housed inside the nucleus and tightly packaged into linear chromosomes. Chromosomes are made of a DNA-protein complex called chromatin which is prepared into subunits called nucleosomes.
All eukaryotes have a well-described nucleus that consists of DNA. DNA is a negatively charged polymer, packed compactly inside the chromatin, engirdling the histone proteins, a ball of positively charged proteins. The octamer of histone proteins is wrapped with a DNA helix, giving rise to a structure known as nucleosomes.

Answers
Adjacent water molecules means those molecules which are present next to other molecules.
What are adjacent water molecules?
In a water molecule, hydrogen bonds are formed between hydrogen and oxygen atoms of adjacent water molecules. The attraction between single water molecules creates a bond which is called a hydrogen bond. Opposite ions attract each other, allowing bonds to form between the hydrogen and oxygen atoms of other adjacent water molecules.
Each water can combine with four neighbors with the help of hydrogen bonds. Hydrogen bonds form between adjacent water molecules because the positive charge hydrogen of one water molecule attracts the negatively charged oxygen atom of another water molecule.
So we can conclude that adjacent means next to other molecules.

A study shows that the reported proportion of deaths due to heart attack in India before Corona infection was 28.9\%. But during Corona infection, the deaths due to heart attack was said to be 'under-reported'. But a Medical researcher believes that the deaths due to heart attack has increased during Corona infection due to non-availability of ICUs. To verify this 'under-reporting' a medical researcher randomly selected 200 deaths in a city and found that 73 were died due to heart attack. Does the data suggest that the deaths due to heart attack has increased as believed by medical researcher? Use α=0.05.
Answers
The p-value for z = 2.0146 is P (Z > 2.0146) = 0.0222. there is sufficient evidence to suggest that the proportion of deaths due to heart attack during Corona infection is greater than the proportion before Corona.
Proportion of deaths due to heart attack in India before Corona infection was 28.9%
Medical researcher believes that the deaths due to heart attack has increased during Corona infection due to non-availability of ICUs. A medical researcher randomly selected 200 deaths in a city and found that 73 were died due to heart attack. Significance level, α=0.05. We need to test the medical researcher's claim of increased deaths due to heart attack during Corona infection. Let p be the proportion of deaths due to heart attack during Corona infection.
Null Hypothesis H₀: p ≤ 0.289 (Proportion of deaths due to heart attack during Corona infection is less than or equal to the proportion before Corona)
Alternate Hypothesis H₁: p > 0.289 (Proportion of deaths due to heart attack during Corona infection is greater than the proportion before Corona)
We will use a one-tailed z-test for testing the hypothesis at 0.05 significance level.
z = (phat - p) / √(p(1-p)/n)
where phat = 73/200 = 0.365
n = 200
p = 0.289
z = (0.365 - 0.289) / √ (0.289(1-0.289)/200) = 2.0146
The p-value for z = 2.0146 is P (Z > 2.0146) = 0.0222.
Since the p-value (0.0222) < α (0.05), we reject the null hypothesis.
Therefore, there is sufficient evidence to suggest that the proportion of deaths due to heart attack during Corona infection is greater than the proportion before Corona.
Yes, the data suggests that the deaths due to heart attack has increased as believed by medical researcher.
