Answer:

Due to mixing of particles present in the upper layer of limestone with sandstone during deposition.

Explanation:

The parent layer was limestone layer which is older than sandstone layer. This sandstone layer spreads on the limestone layer because of wind. The wind moves these sandstone from other region and their deposition occurs on the limestone layer. During deposition of sandstone, some particles of limestone which are present at the surface mixes with the sandstone so that's why in sandstone layer, small and weathered pieces of limestone are present.

The difference in the concentration of molecules in two areas across a membrane is concentration gradient.

In the field of science, concentration gradient can be described as a term that is used when there is a difference in the number of molecules inside and outside the membrane. Due to this difference, molecules either pass into a cell or outside of a cell.

When the concentration of a molecule is higher outside a cell as compared to the inside of a cell, a concentration gradient will develop. As a result of this concentration gradient, molecules will move into the cell.

Answer: The correct answer to the question is option A

SEARCH FOR AN AED.

Explanation: AED stands for Automated External Defibrillator.

It is a machine that is used to re-establish a normal cardiac rythym in cases of cardiac arrest or when the heart stops beating momentarily.

It delivers electric shock via the chest to the heart inorder to stop an an irregular heart rythym and establish an effective one.

From the scenerio in the question,5 cycles and 2minutes of CPR has been done on the victim but no pulse is present, The next best thing to do is to use an AED to shock the victim inorder to re-establish the lost cardiac rythym and pulse respectively.

This is achieved placing the pads on victim, analysis the rythym, move slightly away from the victim to prevent any contact and then shock the victim by pressing the shock button as the AED instructs showing that the rythym presented is a shockable one.

Answer:

CUA

Explanation:

Chances are your teacher accidentally put the same option twice and marked one of em incorrect. You infact selected the correct answer because CUA is correct.

DNA has 4 bases: ATGC (Apples on Trees = A - T, & Cows eat Grass = C-G)

RNA has 4 bases: AUGC  (RNA lacks the base T so A binds with U instead).

So for template strand GAT, the mRNA made from this codon has complimentary pairing based on RNA so G binds with C, A binds with U, and T binds with A.

A triplet of bases in a template strand of DNA is GAT, the corresponding codon for mRNA - CTU

DNA is a two-stranded molecule. Each strand is a polynucleotide composed of A (adenosine), T (thymidine), C (cytidine), and G (guanosine)  in a sequence.

Thus, A triplet of bases in a template strand of DNA is GAT, the corresponding codon for mRNA - CTU

Answer:

The statement that is true about BRCA1 and BRCA2 is that people can be tested for mutations on these genes. A doctor can test a patient for these gene mutations and determine if the patient has a chance at getting hereditary breast cancer and ovarian cancer.

Explanation:

The critical value for a chi-square test is dependent on the degrees of freedom and the level of significance chosen. In the case of a dihybrid cross with three phenotypes, there are three degrees of freedom (df = n - 1), where n is the number of phenotypic categories.

Step 1: Determine the degrees of freedom. The formula for degrees of freedom is (number of phenotypes - 1). In this case, it would be (3-1) = 2.

Step 2: Choose a significance level (alpha). Typically, a 0.05 significance level is used in biological studies.

Step 3: Refer to a Chi-square distribution table with the degrees of freedom and the chosen significance level. In this case, look for the value at 2 degrees of freedom and an alpha of 0.05.

The critical value you use for a dihybrid cross involving a recessive epistatic gene with 3 phenotypes in the F2 generation, using a Chi-square test and a significance level of 0.05, is approximately 5.99.

The coenzymes of folate b-vitamin are needed for the synthesis and maintenance of new cells

B vitamins are a group of water-soluble vitamins that are crucial for red blood cell production and cell metabolism. Despite having names that sound similar (B1, B2, B3, etc.), these vitamins are chemically different substances that frequently coexist in the same foods. Dietary supplements that include all eight are typically referred to as vitamin B complexes. The exact number or name of each vitamin, such as B1 for thiamine, B2 for riboflavin, and B3 for niacin, is used to identify individual B vitamin supplements. Some substances, like pantothenic acid, biotin, and folate, are better known by their names than by their chemical names.

Each B vitamin either functions as a cofactor (usually a coenzyme) for important metabolic processes or functions as a precursor required to produce one.

Answer:

The words that complete the sentences are:

- EUKARYOTIC

- MULTIPLE

- CIRCULAR

Explanation:

Replication is the process whereby genetic material is duplicated into two identical copies. It is a key process that must occur prior to any cellular division (mitosis or meiosis). However, DNA replication occurs slightly different in eukaryote and prokaryote.

- Eukaryotic cells are cells that possess a membrane bound nucleus to house their NUMEROUS/MULTIPLE LINEAR chromosomes. On the other hand, prokaryotic cells do not have a membrane bound nucleus to house their SINGLE CIRCULAR chromosome.

- Due to the fact that linear chromosomes of eukaryotes are multiple in number, their replication occurs in MULTIPLE LOCATIONS but that of prokaryotic cells take place in a SINGLE LOCATION.

Answer:

Bicarbonate ion, HCO3- (which has a similar charge to chloride ions) also follow sodium ions into the blood. Also, potassium ions, K+ are transported into the nephron so some chloride ions and bicarbonate ions remains in the nephron to balance the charge.

Explanation:

Sodium is the primary positively charged electrolyte in extracellular fluid. Most of the solute reabsorbed in the proximal tubule is in the form of sodium bicarbonate and sodium chloride. Water is also reabsorbed in order to balance osmotic pressure

When sodium ions are reabsorbed into the blood, few of the substances that are transported with Na+ on the membrane facing the lumen of the tubules include Cl- ions, Ca2+ ions, amino acids, and glucose. Sodium is actively exchanged for K+ using ATP on the basal membrane.

In the distal convoluted tubule, K+ and H+ ions are selectively secreted into the filtrate, while Na+, Cl-, and HCO3- ions are reabsorbed to maintain pH and electrolyte balance in the blood.

Some chloride ions remains in the nephron to balance the charge of the secreted K+ ions and also due to the bicarbonate ions that are removed.

The concentration of Chlorine decreases as fluids are extracted along the nephron because it is not soluble in water. With an increase in the fluid extraction along the nephron, there is the reabsorption of more water and since Chlorine cannot be diluted by water, its concentration decreases. With the more reabsorption of water and increase in its concentration as the fluid moves through the nephron, the relative concentration of chlorine reduces.

This gradient is mainly caused by NaCl and urea. NaCl is transported by the ascending limb of Henle's loop which is exchanged with the descending limb of the vasa recta.
