Answer 1

Blood glucose concentration is the major controlling factors for insulin levels. Glucose is the principal stimulus for insulin secretion, through other macro-nutrients, hormones, neural inputs may respond according to this insulin.

Tucked away behind the stomach is an organ called the pancreas, which produce insulin.Insulin production is regulated based on blood sugar levels and other hormones present in the human body.When food is digested, glucose is absorbed from human guts into the bloodstream,raising blood glucose levels.

The disruption of a joint in which the bone ends are no longer in contact is called a?

Answers

The disruption of a joint in which the bone ends are no longer in contact is called a Dislocation.

What is dislocation of bone?

When two bones separate where they meet at a joint, it is called a dislocation. The joint may be momentarily deformed and immobilized, and the injury may be excruciatingly painful. Shoulders and fingers are the most frequent sites for dislocations, although they can also happen in the elbows, knees, and hips. The cause is frequently a fall or blow, occasionally while participating in a contact sport. A bone slipping out of a joint is known as a dislocation. For instance, the shoulder is home to a joint where the top of your arm bone fits. You have a dislocated shoulder when it jumps out of that joint or slips out of it. Any joint in your body, whether your knee, hip, ankle, or shoulder, is susceptible to dislocation.

The placenta is formed by endometrial tissue of the uterine lining and the ________

Answers

chorionic villi of the trophoblast

The placenta is formed by endometrial tissue of the uterine lining and the chorion, which is a membrane that surrounds the embryo and helps to form the placenta.

What is the placenta?

The placenta is an organ that develops during pregnancy and connects the developing fetus to the uterine wall to allow for nutrient uptake, waste elimination, and gas exchange via the mother's blood supply.

The placenta also produces hormones that are important for pregnancy, such as human chorionic gonadotropin (hCG) and progesterone. It acts as a barrier, preventing the mother's immune system from attacking the developing fetus. The placenta is usually expelled from the mother's body after the baby is born.

In mri, structural information about the brain can be collected by using strong magnetic fields together with radio waves to manipulate the nuclear _______________ of protons.

Answers

none of the answers in this list of options fills the blank. Strong magnetic fields created by the powerful magnets used in MRIs compel the body's protons to align with the field.

The protons are activated and spin out of equilibrium when a radiofrequency current is then pulsed through the patient, struggling against the magnetic field's pull.Because protons can spin either left or right, which corresponds to a distinct energy state, they have multiple spin configurations. Higher energy states are experienced by protons that align against the external magnetic field as opposed to lower energy states experienced by protons that do so.The hydrogen protons will align themselves once more with the static magnetic field once the energy from the RF pulse is lost. Hydrogen protons serve as the source of the MRI signal since they  move back into alignment with the magnetic field, and fall out of "phase" with each other.

What is a geostrophic wind? Why would you not expect to observe a geostrophic wind at the equator?

Answers

A theoretical wind known as the geostrophic wind is produced when the Coriolis effect, as well as the pressure difference forces, are balanced (PGF). It is a decent estimate for the wind reported at middle latitudes at an altitude of greater than 1 km. Given that there is no Coriolis effect near the equator, there can be no geostrophic wind.

What does "geostrophic wind" mean?

Geostrophic flow, as used in atmospheric research, is the fictitious wind that would emerge from a precise balancing act between the Coriolis effect and the pressure difference forces. The term "geostrophic equilibrium" or "geostrophic balance" refers to this situation (also known as geostrophy). Parallel to the isobars is where the geostrophic wind is pointed. In nature, this equilibrium seldom occurs perfectly. Because of these factors, the genuine wind and geostrophic wind nearly never match up.

The location of geostrophic winds:

At elevations exceeding 1000 meters (3300 feet), geostrophic wind can be found. With the use of weather balloons, the geostrophic wind velocity may be calculated. At heights up to 100 meters, the ground surface has a significant impact on winds.

The choroid is highly vascularized to provide blood to the retina and contains dark pigmentation to stop light from reflecting inside. Anteriorly, the choroid, ciliary body, and iris are all joined.. The ciliary body muscles regulate the lens's thickness. The iris acts as a diaphragm, changing the pupil's aperture at its center. This regulates how much light is allowed to enter the retina.

In our bodies, glucose is broken down into carbon dioxide and water, much like a combustion reaction. How many grams of o2 are needed to fully react with 150g glucose?

Answers

160g of O₂ will be required to fully react with 150g of glucose when glucose is broken down in our bodies to produce carbon dioxide and water.

The breakdown of glucose in our bodies can be represented by the following reaction:

C₆H₁₂O₆(s) + 6O₂(g) → 6CO₂(g) + 6H₂O(g)

As shown in the reaction, a mole of glucose reacts with 6 moles of oxygen.

To calculate the molecular mass:

1 mole of glucose (C₆H₁₂O₆) = (6x12) + (12x1) + (6x16) = 180g

6 moles of oxygen= 6x (2x16) = 192g

180g of glucose reacts with 192g of oxygen. So, to calculate the amount of oxygen required to fully react with 150g of glucose=

150 x 192/180 = 160g of oxygen.

Therefore, 160g of oxygen is required to fully react with 150g of glucose.

Answers

Excessive application of fertilizer

The reason for the pond in the center of the park to now be covered with algae is the excessive application of fertilizer.

A plant can really die from too much fertilizer, and excess fertilizer can cause toxic algal blooms in lakes and streams that are dangerous to people and their pets as well as other aquatic life. Aquatic "dead zones" are also a result of excessive fertilizer runoff from agricultural and lawn applications in coastal areas.

What consequences might excessive fertilizer use have?By increasing the soil's salt concentration, excessive fertilizer changes the soil and might harm beneficial soil microbes. Over-fertilization can result in abrupt plant growth with insufficient roots to provide the plant with enough water and nutrients.

Can plants bounce back after excessive fertilizing?A few straightforward procedures can save the majority of over fertilized plants.

Birds living in this population would have an allele frequency of "b."

NOTE:

The term "recessive allele" refers to the character/allele that is eclipsed by the dominant character, whereas a "dominant allele" is a character/allele whose phenotype is displayed to the complete exclusion of the other character/allele.

When a pair of alleles in a gene are homozygous, they are the same; when they are heterozygous, they are different.
