The organic molecules that formed by the amino acids are known as proteins. Each amino acid binds with other amino acid with the help of peptide bond between amino group of one amino acid and carboxylic group of another amino acid.
Thus, 'when alanine binds with other amino acids, such as with glycine or serine, a protein molecule will formed.'
The main goal of science is to _____. answer all questions solve all human problems understand our environment make models of natural phenomena please answer ASAP
I have post nasal drip, what drug can i take along with metoprolol for this sinus condition?
What does it mean for a membrane to be selectively permeable? Only certain molecules are allowed to pass through.
The membrane is rigid and only allows water to pass through.
All types of molecules are able to pass into the cell.
The membrane is rigid and nothing can enter or leave the cell.
Semi-permeability means that only certain molecules are allowed to pass through.
-Semi-permeability is one of the features of a cell membrane, which means that the membrane allows selective movement of materials in and out of the cell; that is only certain molecules can enter or leave the cell.
-For example smaller molecules such water and ions such as potassium and sodium ions are able to leave and enter the cell, while other molecules that are large such as protein molecules can not enter or leave the cell.
The membrane is said to be semi permeable when only certain molecules are allowed to pass through them.
Semi-permeable membrane is the membrane which allows only a certain molecules to pass through them. This process is a type of diffusion generally does not require any external energy influence.
The diffusion takes place only of those molecules which are permeable through the membrane. This process is generally passive but can be sometimes active. One of the examples of biological semi permeable membrane is lipid bilayer which is the covering of several cells present in the body. It consists of hydrophobic head and hydrophilic tail which is embedded in the layer.
The bilayer is the mode of communication of the cell. External influence changes the structure of protein present in the layer and helps the cell to become selectively permeable. This is how the cell communicates with the surroundings.

What ions must routinely move across cell membranes?
3. What are the advantages of a specific defense?
The immune system is the third line of defense which perform special defenses in the human body. It comprises mechanisms and agents which target particular antigens (Ags) which is known or unknown by humans. An antigen is any particle, ordinarily a protein or polysaccharide can be prevented from entering into body by special defenses.
The immune system defends the body against disease-causing microorganisms. It comprises the two levels of strength, the non-specific defenses, and the specific defenses. The non-specific protection, such as the skin and mucous layers, prevent microorganisms from penetrating into the body.
The advantages of a specific defense are how it will remember certain bad pathogens and fight against them the next time they try to come into your system.

holding at a constant non-zero velocity
Answer:(D) holding at a constant non-zero velocity
Which of the following incorrectly matches the term with its location? DNA is found in a chromosome.
Chromosomes are found in the nucleus of a cell.
Genes are located in a nucleotide.
Nitrogen bases are located in the central rungs of a DNA ladder.
The correct answer is:
Genes are located in a nucleotide. Rather, genes are segments of DNA which can be found within the nuclei of cells.
The large majority of organisms encode their genes in long strands of DNA (deoxyribonucleic acid). DNA consists of a chain made from four types of nucleotide subunits, each formed of a five-carbon sugar (2-deoxyribose), a phosphate group, and one of the four bases adenine, cytosine, guanine, and thymine..There are thereby 20,000 primary genes identified on one of the 23 chromosome pairs found in the nucleus or on long strands of DNA placed in the mitochondria.
Genes are located in a nucleotide.
What is the phenotype of an individual with the genotype SS

a loss of nutrients
an influx of foreign animals
an increase in plant growth
