The flu vaccine (administered as a shot or a nasal spray) is made of a combination of the different types of influenza viruses t

Answer: 0.05 M

Explanation:

To solve this question, one must consider the Law of Conservation of Mass. This law states that in a closed system, the total mass of the participating molecules remains unchanged during a chemical reaction. This implies that the mass in the reactants equates to the mass of the products formed.

In this case, a solution of NaOH (sodium hydroxide) with a molarity of 0.204 (defined as moles per liter of solution) is used, and 16.4 mL of this solution is added to 50 mL of H3PO4 (phosphoric acid) solution.

Since the mass of both solutions is conserved, we can apply the Law of Conservation of Mass equation:

Initial Concentration x Initial Volume = Final Concentration x Final Volume.

Initial Concentration: 0.204 M

Initial Volume: 16.4 mL

Final Concentration:?

Final Volume: 50 mL + 16.4 mL = 66.4 mL

Plugging in the values to the equation:

0.204 M x 16.4 mL = Final Concentration x 66.4 mL

The molarity of the H3PO4 solution calculates to be 0.05 M.

Answer:

AUGUCCCACGAUGGGUGA

Methionine- Serine- Histidine- Aspartate- Glycine- Stop

Explanation:

During the process of gene expression, DNA, which contains genetic information, is transcribed into mRNA, and this mRNA is then translated into a sequence of amino acids. This transcription abides by the rules of complementary base pairing, translating as A-U, G-C, and T-A.

In mRNA, nucleotide sequences are organized into sets of three bases known as CODONS. Each of these codons corresponds to a specific amino acid.

In this scenario, a piece of DNA encodes methionine, serine, histidine, aspartate, and glycine after translation. However, a mutation leads to the sequencing shown: 3' – TACAGGGTGCTACCCACT – 5'.

The mutated DNA's corresponding mRNA sequence would be: AUGUCCCACGAUGGGUGA

Throughout translation, these codons yield the following amino acids:

AUG - methionine

UCC - Serine

CAC - Histidine

GAU - Aspartate

GGG - Glycine

UGA - Stop codon

Therefore, the resultant peptide chain from the revised DNA sequence will be: Methionine- Serine- Histidine- Aspartate- Glycine- Stop

Answer:

2. ER protein

4. insulin

6. lysosomal enzyme

Explanation:

Ribosomes serve as the cellular organelles responsible for synthesizing proteins since they create the necessary environment and machinery for this process.

Ribosomes can exist freely within the cytosol or be attached to the endoplasmic reticulum.

The proteins formed by free ribosomes are typically used within that same cell, such as DNA polymerase and ribosomal proteins, whereas proteins made by attached ribosomes are intended for transport throughout the cell, including insulin and lysosomal proteins.

Consequently, 2, 4, and 6 are correct.

Answer and Explanation:

Typically, sea turtles lay around 110 eggs per clutch. However, only a small fraction of the hatchlings survive to reach the ocean. Subsequently, an even fewer number are able to produce their own young. - Overpopulation

All zebras possess stripes, yet no two zebras exhibit identical stripe patterns. -Variation

A lemur species named aye-ayes feature extended, slender middle fingers that enable them to probe into tree crevices to extract insects for food.- Adaptation

Answer:

Ribosomes, Cell membrane

Explanation:

Ribosomes serve as the sites where proteins are synthesized. Therefore, they are referred to as the protein production factories of a cell. Since enzymes are a type of protein, their synthesis occurs within ribosomes.

The cell membrane functions as the boundary that surrounds the cell or separates it from its environment.

To exit the cell and enter the external environment, an enzyme must navigate through both the ribosomes and the cell membrane.
