How many amino acids does this protein segment contain?

Answers

Answer:  the given protein segment contains 20 amino acids

The given segment of the polypeptide chain is made up of four different types of amino acids, and each amino acid is connected to each other by the peptide bond, and the chain elongates from the N terminal to the C terminal.

What is the significance of amino acids?

There are 20 different standard amino acids that take part in polypeptide chain synthesis, and those are categorized into some particular types such as hydrophobic amino acids, hydrophilic amino acids, charged and uncharged amino acids, etc., and different compositions of the amino acids make different types of proteins. The polypeptide chain is generally synthesized from the N terminal to the C terminal, and here in the given diagram, there are four amino acids, and each amino acid has an amino group, a carboxylic group, a hydrogen group, and one side chain bonded to a single central carbon atom.

Hence, the given segment of the polypeptide chain is made up of four different types of amino acids.

Staphylococcus aureus, or staph, is a bacteria that is commonly found in the nose and on the skin of humans. While it is typically not harmful to humans, it is sometimes able to enter the body through an injury or broken skin, and get into the bloodstream. When this happens, it can cause a serious infection called sepsis. Sepsis can cause an individual to go into shock and bodily organs to stop functioning. Symptoms of sepsis include inflammation, fever or hypothermia, increased heart rate, and rapid breathing.

Answers

Answer:

Has more offspring that have the ability to survive and reproduce themselves.

Explanation:

Evolution fitness can be defined as a characteristic or quality possessed by living organisms and determines their adaptability, as well as level of success in terms of reproduction i.e giving birth to offsprings.

Hence, if you say that a ground squirrel has greater evolutionary fitness than another ground squirrel in the same population, you mean that the animal has more offspring that have the ability to survive and reproduce themselves.

Which parts of DNA provide the code for proteins?

Answers

Answer:

The genetic code is the sequence of nucleotide bases in nucleic acids (DNA and RNA) that code for amino acid chains in proteins. DNA consists of the four nucleotide bases: adenine (A), guanine (G), cytosine (C) and thymine (T). RNA contains the nucleotides adenine, guanine, cytosine and uracil (U).

A gene is a section of a DNA molecule that contains the information to code for one specific protein.

The DNA code contains instructions needed to make the proteins and molecules essential for growth, development and health.

What is gene?A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins.  Many genes do not code for proteins.

What is DNA?

DNA is the genetic material, which is involved in carrying the hereditary information, replication process, mutations, and also in the equal distribution of DNA during the cell division.

They reproduce sexually and have many traits that are easy to observe.

Answers

Answer:

For Gregor Mendel, pea plants were fundamental in allowing him to understand the means by which traits are inherited between parent and offspring. He chose pea plants because they were easy to grow, could be bred rapidly, and had several observable characteristics, like petal color and pea color.

Explanation:

Gregor Mendel chose the pea plants for his experiments because the garden pea is an ideal subject in the study of genetics for the following reasons: The presence of observable traits with contrasting forms. It produces many offspring in one cross. Short life cycle.

Why did Mendel choose pea plants to study?

Solution: Pea plants were chosen for Mendel's experiments because they are easy to grow, have a short life period, and produce larger flowers. Pea plants are also self-pollinated.

What was the purpose of the pea plant study?

Gregor Mendel describes his experiments with peas showing that heredity is transmitted in discrete units. From the earliest time, people noticed the resemblance between parents and offspring, among animals and plants as well as in human families. Gregor Johann Mendel turned the study of heredity into a science.

A girl is born with hemophilia. Her dad also has hemophilia, but her mother does not.

What genetic explanation can you provide as to why the girl
suffers from hemophilia?

Answers

answer:

So daughters get 2 X chromosomes from the mom and dad and if the dad has hemophilia the daughter would get it too and sons would not get because they get Y chromosome from their dad and hemophilia is found in the X chromosome because the X chromosome is the one that has the instructions for making the clotting factor proteins.

Explanation:

A father who has hemophilia has the gene and passes it on to his daughter because daughters get two X chromosomes, one from their mother and the other from their father. This is why daughters of men with hemophilia are called obligate carriers. Since sons only receive a Y chromosome from their father, they would not have inherited hemophilia.

A scientist observed that during the course of a chemical reaction the number of ATP molecules were converted into ADP. What did the scientist most likely learn from the observation? a The reaction caused an output of energy. b The reaction produced water. c The reaction consumed water. d The reaction required an input of energy.

Answers

Answer:

a The reaction caused an output of energy

Explanation:

Adenosine triphosphate, commonly known as ADP, is an high-energy storage molecule in living cells. It stores and transfers needed energy for metabolic activities. ATP stores its energy in the bonds that hold the phosphate group in its structure. However, the energy is released for use during metabolic processes when the phosphate bond is broken, leading to the release of ADP molecule.

In this case, a scientist observed that during the course of a chemical reaction the number of ATP molecules were converted into ADP. This means that the reaction has caused ATP molecules to release its stored energy i.e. an energy output.

If the mrna is damaged, it directly interferes with the ability of a animal cell to do which of the following?

Answers

Answer:

Proteins.

Explanation:

If the mRNA is damaged, it directly interferes with the ability of producing proteins in animal cell because mRNA is responsible for carrying the protein blueprint from a cell's DNA to its ribosomes which are considered as the machines of the cell that produces proteins for the cell. These messenger RNA has the information about what type of proteins are required to produced for the cell. So if mRNA is damaged, the ribosomes are unable to produce proteins for the cell.

what is the primary difference between diffusion and osmosis

Answers

Long answer here!

In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration.

The movement of particles (such molecules or ions) from a region of higher concentration to a region of lower concentration is known as diffusion.

Thus, It happens in a variety of media, including gases, liquids, and solids. The inherent propensity of particles to travel down their concentration gradient in search of equilibrium is the driving force underlying diffusion.

On the other hand, osmosis is a particular kind of diffusion that entails the passage of water molecules over a membrane that is only permeable in certain places. It happens when the solute concentrations on opposite side of the membrane differ.

Thus, The movement of particles (such molecules or ions) from a region of higher concentration to a region of lower concentration is known as diffusion.
