The proper function of the stomates on the leaf (and therefore, the function of water and CO2 movement) is influenced most by which element
Answer:
Sunlight.
Explanation:
Sunlight is responsible for proper functioning of stomata present on the leaves because the stomata only opens when there is sunlight and when the stomata opens, carbondioxide gas is absorbed by the leaves from the air while the water is taken from the roots which combines together to form glucose and oxygen. Glucose is stored in different parts of the plant while some oxygen is used by the plants in the process of respiration while the remaining oxygen is released in the atmosphere through stomata.
Where in the chloroplast does the light independent reaction occur
Answer:
In photosynthesis, the light-dependent reactions take place on the thylakoid membranes. The inside of the thylakoid membrane is called the lumen, and outside the thylakoid membrane is the stroma, where the light-independent reactions take place.

what is the primary difference between diffusion and osmosis
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.

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.
A microscopic image of staphylococcus aureus is shown.
Which immune system component initially results in the inflammation and responds quickly when Staphylococcus aureus enters the bloodstream?
complement system

Which of the following is an example of specific immunity?
Answer:
Immunity to Small Pox
Explanation:
Over the years, Europeans had built up an immunity to smallpox because many had contracted the disease and still survived. As the population grew children were born with some immunity to the disease. When the Europeans arrived in the Americas, and smallpox spread around the native peoples, the Europeans did not contract the disease because they were immune. However, since the natives were not immune, they slowly died of due just to the disease as well as some parts of the war between the europeans.
Which parts of DNA provide the code for proteins?
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.

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?
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.

Why did Mendel study pea plants?
They reproduce asexually and have one trait that is easy to observe.
They reproduce asexually and have many traits that are easy to observe.
They reproduce sexually and have one trait that is easy to observe.
They reproduce sexually and have many traits that are easy to observe.
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.

How many amino acids does this protein segment contain?
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.
