The vascular cylinder is located on bundles across the root organ, while the epidermis and cortex are located on the surface of this organ.
What are the plant epidermis and cortex?
The plant epidermis is a surface layer that covers all plant organs in order to protect them, including the root, while the plant cortex is a type of unspecialized tissue located among plant epidermis tissue and bundles of vascular tissue. In turn, the vascular tissue is composed of phloem and xylem.
Therefore, with this data, we can see that the plant epidermis and cortex are located in series on the surface of the root organs, and they cover the vascular tissues such as the phloem and also the xylem responsible to transport different nutrients and waste materials from the plant root to all other plant organs (i.e. the shoots and leaves)

What are three 3 important parts that can be found in the structure of an atom?
Answers
The three important parts that can be found in the structure of an atom are protons, neutrons, and electrons. Protons are positively charged particles located in the nucleus of an atom.
They have a mass of 1.6726 x 10-27 kg, which is approximately 1800 times the mass of an electron. In an atom, the number of protons equals the number of electrons, and the number of protons determines the element. For example, hydrogen has one proton, helium has two protons, and so on.
Neutrons are neutral particles located in the nucleus of an atom. They have a mass of 1.6749 x 10-27 kg, which is approximately the same as the mass of a proton. Neutrons can help to stabilize the nucleus of an atom by increasing its mass and preventing it from decaying. The number of neutrons in an atom varies, and can be different from the number of protons. This can lead to different isotopes of the same element.
Electrons are negatively charged particles located in the electron cloud, which is the region of space surrounding the nucleus of an atom. They have a mass of 9.109 x 10-31 kg, which is approximately 1/1800th.

Answers
In the night time, the pH of the water became acidic because of the reverse reaction of photosynthesis in which Hydrogen ions were produced as result.
In the dark condition or night when sufficient amount of sunlight is not present, plants do no undergo photosynthesis. This is because in absence of light, plants are unable to use carbon dioxide and water to produce glucose and O2 as sunlight acts as a catalyst to begin the reaction. During day, underwater photosynthesis rate exceeds respiration in plants. In dark, the plants respire like normal animals wherein they release carbon dioxide and water vapors are produced. These water vapors are in the form of hydrogen ions which makes the pH acidic. Carbon dioxide in itself is not acidic as such.

Answers
a cell typically spends 95 percent of the time required to complete a full cell cycle in interphase.
cell cycle can be broadly divided into 2 phases:
interphaseM phase
Interphase is the time when the cell prepares for division by going through both cell growth and DNA replication. It is often referred to as the resting phase of the cell cycle. It is further divided into:
The G1 phase: (also known as the "Gap 1") is the time period a cell goes through between the completion of mitosis and the start of genetic material replication. The cell is metabolically active and continues to expand throughout this stage without repeating its DNA.
S phase: DNA replication occurs in the S phase (Synthesis), which is the next phase. If the cell's starting DNA content is represented as 2N, replication results in 4N. However, the number of chromosomes does not change; for example, if 2n chromosomes were present during the G1 phase, they would still be present by the conclusion of the S phase. In cells that contain centrioles, the centriole also splits into two centriole pairs.
G2 phase: As the cell gets ready to enter the mitotic phase, the G2 phase (also known as the "Gap 2") is where the RNA, proteins, and other macromolecules needed for the expansion of cell organelles, spindle formation, and cell development are created.

The varying morphology of red blood cells due to pitting, culling, filtering, and persistence of abnormal red blood cells in the peripheral blood is most likely caused by splenectomy
Red blood cells or erythrocytes are the most numerous blood cells in the body and are produced in the spinal cord. Inside the red blood cells, hemoglobin is stored, which is a respiratory pigment that binds oxygen or carbon dioxide molecules. Oxygen will be transported to various tissues and organs of the human body. The characteristics of red blood cells are red, flat in shape, and do not have a cell nucleus.
Splenectomy is a procedure performed by surgeons to remove the spleen and treat blood diseases such as hemolytic anemia. In hemolytic anemia, the red blood cells are abnormal so that antibodies attack the red blood cells and are destroyed by the spleen. Then splenectomy is needed to prevent blood transfusions.

Answers
If the resistant individuals continue to survive and prosper, new resistant populations might emerge. this would be an example of natural selection
Natural selection is where specific qualities or features, depending on their propensity to aid individuals in surviving and procreating, gradually become more or less prevalent in a population over time. Chytridiomycosis-resistant people who endured and thrived despite the illness have an attribute that has made it possible for them to do so. This characteristic may be inherited genetically from one parent to the next or it may be acquired by process, like building up immunity through exposure to the disease.
New resistant populations will form as long as these resilient people persist and procreate, passing on their resilient traits to their progeny. If the disease's selective pressure persists, the proportion of resistant people in the population is likely to rise over time while the proportion of non-resistant people falls.

Can B12 deficiency cause acid reflux?
Answers
yes. B12 deficiency cause acid reflux. To be bioavailable throughout the remainder of the body, vitamin B12 must interact with stomach acid. Consequently, a B12 shortage can lead to digestive and heartburn issues.
Barrett's esophagus (BE), erosive esophagitis, and vitamin D insufficiency are all linked to one another, as is hyperparathyroidism, which is linked to both erosive esophagitis and BE. A lower risk of problems from acid reflux may be associated with taking B vitamins. They might possibly lessen heartburn symptoms when combined with other substances, although additional research is required. In the stomach, enzymes and hydrochloric acid release vitamin B12's ligands to release it into its free form. The vitamin B12 is then able to be absorbed farther down in the small intestine by joining forces with a protein known as intrinsic factor. The free form of B12 is present in supplements and foods that have been fortified, making them potentially more absorbable.

Your lab partner is upset because she loves nasturtium flowers, but she cannot get her dormant nasturtium seeds to germinate. as you examine the seeds, you note a very thick seed coat on the seeds. what might you suggest to her to improve germination
Answers
She can see if there is some kind of film on the seed or she can slightly crack the seed to speed up the process
To break the dormancy of nasturtium seeds, various options can be suggested, such as stratification, scarification, pre-sowing treatment or buying fresh seeds.
What is stratification?
If your lab partner is having trouble germinating nasturtium seeds due to their thick seed coat, you can suggest scarification which involves breaking or weakening the seed coat for better water and air penetration or rubbing the seeds gently with sandpaper with a sharp blade for water and air penetration inside the seed.
