What is financial risk in project?Most health insurance companies only cover the lowest version of a drug. It is nearly identical to the branded medicine or includes the same active component. If your doctor has prescribed the more expensive medication for a medical condition, your insurer could agree to pay for it. For instance, you might have an allergy to a component of the less expensive medication. In that situation, the prescription must be marked as "medically required" by the physician.
Construction risk, operational risk, supply risk, offtake risk, repayment risk, political risk, currency risk, and authorizations risk are typical project financing concerns. - The risk of conflict settlement Project finance is a type of secured loan distinguished by complex, yet fair, risk allocation plans.

What day is considered to be the first day of a female's reproductive cycle?
• When hormone levels are low and the uterus lining is shed.
• When hormone levels are high and the uterus lining is shed.
• When hormone levels are low and the ovary releases an egg.
• When hormone levels are high and the ovary releases an egg.
Question: What day is considered to be the first day of a female's reproductive cycle?
Answer: When hormone levels are low and the uterus lining is shed.
The first day of a female's reproductive cycle is when hormone levels are low and the ovary releases an egg. This is known as ovulation and is the most important part of a woman's menstrual cycle.
What happen during ovulation?During ovulation, the egg's follicle bursts open and is released, travelling down the fallopian tube towards the uterus.
If the egg is fertilised, it will implant in the uterus and a pregnancy will begin; if it is not, it will be reabsorbed by the body, and the cycle will restart.

Which types of muscle can
be conditioned to improve
their function?
Cardiac and skeletal muscle
Smooth and rough muscle
Answer:
Skeletal muscle – the specialised tissue that is attached to bones and allows movement. Together, skeletal muscles and bones are called the musculoskeletal system (also known as the locomotor system). Generally speaking, skeletal muscle is grouped into opposing pairs such as the biceps and triceps on the front and back of the upper arm. Skeletal muscles are under our conscious control, which is why they are also known as voluntary muscles. Another term is striated muscles, since the tissue looks striped when viewed under a microscope.
Smooth muscle – located in various internal structures including the digestive tract, uterus and blood vessels such as arteries. Smooth muscle is arranged in layered sheets that contract in waves along the length of the structure. Another common term is involuntary muscle, since the motion of smooth muscle happens without our conscious awareness.Cardiac muscle – the muscle specific to the heart. The heart contracts and relaxes without our conscious awareness.

A larger population density will help reduce the average costs of the transport network. Areas of high population density have not seen the food shortages because of improved yields from agriculture and the ability to trade food. Economic growth will be comparatively more than low density area.
What are some land adaptations of vertebrates?
The vertebrates that first invaded the land possessed a series of pre-adaptations, such as air-breathing and limb-based locomotion, that allowed them to move about effectively on land; however, other behaviors such as reproduction and swallowing likely tied these vertebrates to the water
When moving to land, animals faced several changes to adapt to the new environment, like lung and limbs development, tegumentary cover, and internal fertilization.
Which are the adaptations of vertebrates to land habits?
Any change to a new environment needs adaptations.
Aquatic animals had to face many changes in their morphology and physiology when changing to terrestrial habits. Some of them are,
Lung developmentThe most significant change is probably lung development, needed to produce gas interchange between tissues and the air.
Once on the ground, animals need to interchange oxygen and carbon dioxide with air. They managed to do so through the respiration process in which the circulatory and respiratory systems work together.
Tegumentary coverAnimals needed to develop a new thicker and harder tegumentary cover.
It needed to be more resistant, especially to avoid or reduce dehydration.
Also, the tegument provides protection when facing new environmental pressures -predation among them-.
Limbs developmentAnother significant change was limb development, which was obviously needed to move on the ground.
Locomotion on the ground required a new pattern of bone arrangement and many muscle changes.
The muscular system suffered many modifications because animals needed to move facing gravity pressure.
Internal fertilizationAnimals needed to face another change related to their reproductive system.
They could no longer make use of external fertilization, as they used to do in aquatic environments.
They developed reproductive organs needed to insert sperm cells into the female body and fertilize the egg cells inside the females.

A normal breath takes in about 1.0 L of air. If air has an average molar mass of 28.8 g per 1 mol and has a density of 0.97 g/mL, how many molecules of air do you take in with each breath
Taking into account the definition of density and Avogadro's Number, you take 2.0286×10²⁵ molecules of air.
What is densityDensity is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.
In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance.
Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:
[tex]density=\frac{mass}{volume}[/tex]
What is Avogadro's NumberAvogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.
Amount of molecules of airIn this case, you know that:
Density= 0.97 [tex]\frac{g}{mL}[/tex]Volume= 1 L= 1000 mLReplacing in the definition of density:
[tex]0.97 \frac{g}{mL}=\frac{mass}{1000 mL}[/tex]
Solving:
mass= 0.97 [tex]\frac{g}{mL}[/tex] ×1000 mL
mass= 970 g
Air has an average molar mass of 28.8 g per 1 mol. Then 970 grams are contained in 33.68 moles.
Now, considering the definition of Avogadro's number you can apply the following rule of three: If 1 mole of air contains 6.023×10²³ molecules, 33.68 moles contains how many molecules?
amount of molecules = (33.68 moles× 6.023×10²³ molecules)÷ 1 mole
amount of molecules= 2.0286×10²⁵ molecules
Finally, you take 2.0286×10²⁵ molecules of air.

When you become too cold, your hypothalamus will signal what parts of your body to raise the temperature?
A. Kidneys and lungs
The hypothalamus notices a decrease in body temperature, it sends signals to muscles and skin.
How does the hypothalamus work?Human performance is best when their body temperature is 37 ° C or 98.6° F. The equilibrium of temperature (Homeostasis) is disrupted whenever body temperature rises or increases.Together, the body's organ systems try to sustain homeostasis instinctively and cognitively. They adapt naturally to fluctuations in their external surroundings in order to keep the internal atmosphere at the best possible conditions for wellness.The brain region known as the hypothalamus is responsible for preserving the body's internal equilibrium. It is the area of the brain that keeps track of processes including body temperature, appetite, and the release of different hormones.The hypothalamus is the first organ to notice a decline in body temperature so that homeostasis can be maintained. The message is sent to the muscles and skin, which causes one to tense up and shiver as the blood vessels under the skin tighten.Therefore, it is concluded that when we feel too cold muscles and skin work to raise the temperature directed by the hypothalamus.
