Tissue
What Does It Secrete, Absorb, or Store?
Most of the secretory and absorptive tissues are epithelial tissues, while those that act as storage units are connective tissues and simple cuboidal epithelium and simple columnar epithelium are useful in the absorption and secretion of molecules during active transport.
What are Absorptive tissues?Most of the absorptive tissues contain epithelial cells that protect the human body from dangerous components in ingested foods where epithelial cells are important gateways to the human body.
Simple columnar epithelia are epithelia specialized for absorption that often have apical cilia or microvilli where these cells line the stomach and intestines.

The 5' end of mRNA serves as a binding site for __________, which allow translation to begin.
a.The promotor proteins
b.The ‘A’ site of the large ribosomal subunit
c.tRNA
d.Initiation factors
Each mRNA molecule being translated often undergoes numerous initiations. The 5′ end of the mRNA is threaded into a new ribosome as soon as the previous ribosome has translated enough of the nucleotide sequence to move out of the way. Hence, it allows the translation to begin.
A ribosome outside the nucleus decodes messenger RNA (mRNA) during translation to produce a specific polypeptide or amino acid chain. The polypeptide performs its unique functions inside the cell after folding into a functional protein. The ribosome facilitates decoding by promoting the binding of complementary tRNA anticodon sequences to mRNA codons. The tRNAs transport certain amino acids that are linked together to form a polypeptide as the mRNA passes through and is "read" by the ribosome.

3. Which letter refers to the change in free energy of the reaction?
The given reaction is an exergonic reaction. In an exergonic reaction, the reactant's free energy is more than the products.
Why is the the reactant's free energy more than the products?This is because an exergonic reaction releases energy as the reactants are converted to products. The released energy comes from the potential energy stored in the chemical bonds of the reactants. As a result, the products have less free energy than the reactants, since some of the potential energy has been released as usable energy (such as heat or work) during the reaction. The difference in free energy between the reactants and products is k.

In snapdragons plants , the alleles for red and white flowers show incomplete dominance and results in a pink flower . Cross a pink snapdragon with a pink snapdragon . Show genotypic and phenotypic percentages of the generation
Answer:
In snapdragons, the gene for flower color has two alleles, R (red) and W (white). If a plant has the genotype RR, it will have red flowers, if it has the genotype WW, it will have white flowers, and if it has the genotype RW, it will have pink flowers because of incomplete dominance.
When two pink snapdragons (RW x RW) are crossed, their offspring will have the following genotypic and phenotypic ratios:
Genotypic ratios:
RR: 25%
RW: 50%
WW: 25%
Phenotypic ratios:
Red flowers: 25%
Pink flowers: 50%
White flowers: 25%
In this case, half of the offspring will have the same genotype (RW) and phenotype (pink) as the parents, while the other half will have different genotypes (RR and WW) and phenotypes (red and white).

NOTEBOOK
5. Conduct Research Use an online search engine to research more information about
mRNA drugs, their uses, and their development. Be sure to take notes and to cite your sources.
The text: What happens when you take a conventional drug, such as aspirin or penicillin? The drug
travels through the blood stream, and then is absorbed by body cells or (as with penicillin)
by the cells of bacteria or other invaders. The drug does its work, but eventually it goes
away. Enzymes and other mechanisms break apart drugs and remove them from the body.
Today, researchers are trying to develop drugs in a very different way. The new drugs are a
modified form of messenger RNA (mRNA). Instead of directly completing the tasks of the
drug, the modified mRNA enters the cell and directs protein synthesis. Then the protein
takes action as a drug or medicine. The protein might be a vaccine or antibody, or it might
be an enzyme that the body cannot make or that it needs in an increased supply.
To develop mRNA drugs, researchers had to find a way to make the molecules last longer
in the body than they generally do. They also needed to "trick" the target cell into
recognizing and accepting the drug. Otherwise, the cell might attack the drug as if it were
a virus.
Researchers met both challenges with the same solution. The drug is not quite the same as
the natural mRNA found in cells. Instead, it uses a few nucleotides that are slightly
different from the normal nucleotides found in RNA. The modifications make the mRNA
both more stable and less virus like.
Answer:
The text describes the development of mRNA drugs and how they differ from conventional drugs. mRNA drugs work by directing protein synthesis inside the cells, and the protein produced by the cell acts as the drug. To develop mRNA drugs, researchers had to find a way to make the molecules last longer in the body and to avoid the cell recognizing the drug as a virus. The solution was to modify the mRNA so that it is different from the natural mRNA found in cells, making it more stable and less virus-like. The text does not directly address the hypothesis about whether mRNA can be replaced with other types of RNA for the therapy to work. However, it does suggest that the modifications to the mRNA are key to the drug's effectiveness and stability.

What is the cell membrane, what is its function and structure, and how does it work?
Answer:
The cell membrane, also known as the plasma membrane, is a thin, semipermeable membrane that surrounds the cytoplasm of a cell and separates it from the external environment. Its main function is to control the movement of substances into and out of the cell, as well as to maintain the cell's internal environment. The cell membrane is composed of a phospholipid bilayer, with proteins and carbohydrates embedded in it.
The cell membrane works by having molecules move from an area of higher concentration to an area of lower concentration. This movement is caused by the molecules having kinetic energy, which causes them to move around randomly. As they move, the molecules spread out, causing the concentration of the molecules to decrease in the area they are moving away from and to increase in the area they are moving towards. The cell membrane is semipermeable, meaning that it allows certain molecules to pass through it, while blocking other molecules. The molecules that are allowed to pass through the cell membrane must be small enough, and have the right type of charge, in order for them to fit through the phospholipid bilayer.
Answer:
What is Cell membrane : A thin membrane that surrounds the protoplasm of every cell.
Function : It provides rigidity and protection to the cell against variations in the environment. It also gives a definite shape, size and support to the cell.
Structure: It is an outer covering of the other cells organelles of the cell.

In a chemical reaction, bonds in reactant molecules are broken and new bonds
are formed to yield products.
How does an enzyme make this happen at an optimal rate in a cell?
A. It lowers the amount of energy needed to break the bonds in the products.
B. It increases the amount of energy needed to break the bonds in the
substrate.
C. It increases the amount of energy needed to break the bonds in the
products.
D. It lowers the amount of energy needed to break the bonds in the
substrate.
Answer:
D. It lowers the amount of energy needed to break the bonds in the substrate.
Explanation:
Enzymes play a crucial role in catalyzing chemical reactions in cells. They do so by lowering the activation energy required for a reaction to occur. An enzyme works by binding to a specific substrate, or reactant molecule, and creating an environment around it that makes it easier for the substrate's bonds to break and for new bonds to form. This allows the reaction to proceed at a much faster rate than it would without the enzyme.
In this context, the correct answer is (D) It lowers the amount of energy needed to break the bonds in the substrate. This is because the enzyme acts to lower the activation energy required for the substrate's bonds to break, allowing the reaction to occur more easily and at a faster rate. By reducing the energy needed to initiate the reaction, the enzyme makes it more likely that the reaction will occur, and thus the rate at which products are formed is optimized.
