Answer:
Among the principal functions of the small intestine, we might mention the peristaltic movement, secretion through special glandules, digestive function, absorptive functions, secretion functions, and endocrine functions.
Explanation:
The whole digestive tube is approximately eleven meters long, from the mouth to the anus.
The small or thin intestine is the longest organ of the digestive tube. It can reach up to 7 meters long, up to 3 centimeters in diameter, and it characterizes by being folded. These folds are called villi, they project into the intestine light, and they are more concentrated in the first portion of the intestine, the duodene, decreasing to the final region of the organ.
Among the principal functions of the small intestine, we might mention the peristaltic movement, secretion through special glandules, digestive function, absorptive functions, secretion functions, and endocrine functions.
The small intestine receives food from the stomach, and through peristaltic movements, it mixes and carries the material to different regions in the organ. The complex polymeric molecules are digested and transformed into simpler substances. The duodene receives secretions from intestinal glands such as bile and pancreatic juices and mixes them with digestive juices of its production. All of these secretions carry huge amounts of enzymes that will degrade food and transform it into soluble substances, such as amino acids. The intestine walls are covered by villi that increase the absorption surface area. Nutrients are absorbed by primary cells and transported to the bloodstream. Calciform cells secrete mucus to protect the epithelium during digestion. Villi also transport water from the blood to the intestinal tract, which helps in food decomposition. Enteroendocrine cells secrete hormones to the blood vessels and capillaries that enter each villus. When nutrients are small enough they go to enter the bloodstream.
Peyer's patches are nodules or cumulus of lymphatic tissue and other accessory cells, located under the mucosa of the gastrointestinal tract, specifically in the lamina propria of the thin intestine, in the jejunum region. These patches represent the mucosa´s immunity system. In the jejunum, these follicles are isolated from each other in the intestine and low concentrated. But in the terminal ileum (The last portion of the thin intestine) they get so close that they might form a plaque.

The major weakness in the California Water Plan are no power to regulate water, not having stationary bodies, and has no effect on the rivers feeding into California from other states. The correct option is B.
What is California Water Plan?The California Water Plan is the state's clear strategy for preserving and expanding water resources in a sustainable manner for both present and future generations.
The WAP has three goals:
More safe water shipments.Revival of essential species and habitat.A more resilient, sustainable, and managed water resources system.The California Water Plan's major flaws are
It does not have the authority to regulate water, only to analyze the situation and advise policymakers.It excludes from its analysis stationary bodies of water such as lakes. It only looks at streams and rivers.It only governs California's water sources and has no bearing on rivers that flow into California from other states.Thus, the correct option is B.

If the pituitary is so important and Eric is not getting replacements of hormones the pituitary makes (except for ADH), why isn’t he dead? To answer this question, think through the cascade of events from hypothalamus to effect.
Answer:
The absence of ADH is not too dangerous.
Explanation:
If there is no place for the storage of ADH hormone in the pituitary hormones, no death occur of the individual because ADH is related to the conserve of fluid in the blood. If this hormone fails to perform its function properly, it causes the body to retain too much water. This more water retention may cause you to feel heavier than normal, and less active so the person did not die due to the deficiency of this disease.

PLEASE HELP!!!? Are humans an invasive species? Why or why not. GIVE TWO PIECES OF EVIDENCE TO SUPPORT YOUR OPINION.
Answer:
I think yes, humans are an invasive species.
Explantation:
I think humans are an invasive species because they are everywhere, and very few places in the world do not have humans. Humans are in control of the planet because of their number. Humans are not going to be extinct ever. They are always going to be here on earth. If somebody finds new land, they make a base/camp and send other people to live there and to populate it. Like in North america, settlers came and sent men to live there. They hunted animals and set up homes. Then, more and more people came and soon all that is left is a over populated land with citys and cars and humans everywhere.

1. Identify one environmental factor that could cause a base sequence in DNA to be changed to a different base sequence.
2. Explain why, in a mammal, a mutation in a gamete may contribute to change in the population of the organism while a mutation a body cell will not.
Answer:
Explanation:
1 Long term exposure to harmful genotoxic chemicals or ionizing radiation can cause changes in the base sequence of DNA.Chemicals might induce DNA mutations, such as polycyclic hydrocarbons (fumes found in oil stations, or smoke from a tobacco cigarette), intercalating agents such as Ethidium Bromide (carcinogen), but also radiations such as UV-radiation (C and T bases are most vulnerable and would bind to identical bases unstead of their
2 Genetic changes that are described as de novo (new) mutations can be either hereditary or somatic. In some cases, the mutation occurs in a person’s egg or sperm cell but is not present in any of the person’s other cells. In other cases, the mutation occurs in the fertilized egg shortly after the egg and sperm cells unite. (It is often impossible to tell exactly when a de novo mutation happened.) As the fertilized egg divides, each resulting cell in the growing embryo will have the mutation. De novo mutations may explain genetic disorders in which an affected child has a mutation in every cell in the body but the parents do not, and there is no family history of the disorder.
Somatic mutations that happen in a single cell early in embryonic development can lead to a situation called mosaicism. These genetic changes are not present in a parent’s egg or sperm cells, or in the fertilized egg, but happen a bit later when the embryo includes several cells. As all the cells divide during growth and development, cells that arise from the cell with the altered gene will have the mutation, while other cells will not. Depending on the mutation and how many cells are affected, mosaicism may or may not cause health problems.

Which soil-based compounds do plants use to create amino acids from glucose?
Answer:
Explanation:
When combined with nitrates from the soil, glucose will form amino acids. When amino acids join together, they form proteins. So, think of glucose as an important source of carbohydrates and, in the right combination, as part of a protein. Without glucose, plants won't grow or reproduce.
NITRATES are the soil-based compounds that plants use to create amino acids from glucose.
WHY DO PLANTS NEED AMINO ACIDS?
Plants require amino acids in order to synthesize proteins, which serves as the hormones and enzymes that carry out metabolic activities.WHAT ARE NITRATES?
Nitrates are nitrogenous compounds (NO3) found in the soil. Nitrogen in the atmosphere (N2) is fixed by certain bacteria called NITRIFYING BACTERIA. This nitrogen fixation process makes nitrogen available in the soil in form of nitrates, which is the only usable form for plants.Plants synthesize amino acids, which are precursors of proteins, by combining the glucose made from photosynthesis with the nitrates absorbed from the soil.
Therefore, the soil-based compounds that plants use to create amino acids from glucose is NITRATE.

The mechanism by which plants convert carbon dioxide, water, and sunshine into oxygen and sugar-based energy is known as Photosynthesis.
What steps are involved in a plant's photosynthesis?Green plants and various other organisms convert light into chemical energy through a process called photosynthesis. Light energy is gathered and utilised during photosynthesis in green plants to change waters, carbon dioxide, and minerals into oxygen- and energy-rich organic molecules.
What makes photosynthesis so crucial?The significance of photosynthesis Solar or radiant energy is converted into chemical energy during photosynthesis. The production of agricultural crops is directly impacted by the rate of photosynthesis. All living things require oxygen, which it provides for the atmosphere. It keeps the ecosystem's carbon dioxide and oxygen levels in check.
