The hardened skin along the proximal edge of the nail is called the "cuticle" or "eponychium."

The eponychium is a small band of skin that covers the base of the nail and helps to protect the nail matrix, which is the area where new nail cells are produced. The eponychium also helps to guide the nail plate as it grows and helps to prevent debris and bacteria from getting underneath the nail plate.

Sometimes, the eponychium can become inflamed and swollen, resulting in a condition known as paronychia. Paronychia can be caused by a bacterial or fungal infection, trauma to the nail, or other skin conditions such as eczema or psoriasis. In severe cases, paronychia can lead to abscess formation and require medical treatment. Regular hand washing, proper nail care, and avoiding biting or picking at the nails can help prevent paronychia.

As air is inhaled, the structure that is last encountered is :

b. alveoli.

As air is inhaled, it first enters the nasal cavity or mouth, then passes through the pharynx, larynx, trachea, bronchi, bronchioles, and finally reaches the alveoli, which are the tiny air sacs in the lungs where gas exchange occurs.

The alveoli are the primary sites of gas exchange in the lungs. Oxygen from the inhaled air diffuses across the thin walls of the alveoli into the surrounding capillaries, while carbon dioxide from the bloodstream diffuses in the opposite direction to be exhaled. This exchange of gases occurs across the alveolar membrane, allowing oxygen to enter the bloodstream and carbon dioxide to be removed.

Thus, the correct option is : (b) alveoli

(i) BEP in $: $8,000

BEP in units: 100 units

(ii) Profits made when sales are 240 units: $4,800

(i) BEP in $ and units:

To find the Break-Even Point (BEP) in dollars, we need to divide the fixed expenses by the contribution margin per unit. The contribution margin per unit is the selling price minus the variable cost per unit.

BEP in $ = Fixed expenses / Contribution margin per unit

BEP in $ = $8,000 / ($120 - $80) = $8,000 / $40 = $8,000

The BEP in dollars is $8,000.

To find the BEP in units, we divide the fixed expenses by the contribution margin ratio.

BEP in units = Fixed expenses / Contribution margin ratio

Contribution margin ratio = Contribution margin per unit / Selling price per unit

Contribution margin ratio = ($120 - $80) / $120 = $40 / $120 = 1/3

BEP in units = $8,000 / (1/3) = $8,000 * 3 = 300 units

The BEP in units is 300 units.

(ii) Profits made when sales are 240 units:

To calculate the profit, we need to subtract the total costs (fixed costs + variable costs) from the total sales.

Variable costs = Variable cost per unit * Number of units sold

Variable costs = $80 * 240 = $19,200

Total costs = Fixed expenses + Variable costs

Total costs = $8,000 + $19,200 = $27,200

Profit = Total sales - Total costs

Profit = (Selling price per unit * Number of units sold) - Total costs

Profit = ($120 * 240) - $27,200

Profit = $28,800 - $27,200

Profit = $1,600

The profit made when sales are 240 units is $1,600.

CVP Analysis:

Cost-Volume-Profit (CVP) analysis is a tool used to analyze the relationship between costs, volume, and profits. It helps in understanding how changes in sales volume affect profitability.

In this case, the CVP analysis can be performed using the given data:

Sales revenue = Selling price per unit * Number of units sold

Sales revenue = $120 * 240 = $28,800

Variable costs = Variable cost per unit * Number of units sold

Variable costs = $80 * 240 = $19,200

Contribution margin = Sales revenue - Variable costs

Contribution margin = $28,800 - $19,200 = $9,600

Contribution margin ratio = Contribution margin / Sales revenue

Contribution margin ratio = $9,600 / $28,800 ≈ 0.3333

Break-Even Point (BEP) in units = Fixed expenses / Contribution margin per unit

BEP in units = $8,000 / $40 = 200 units

Profit = (Selling price per unit * Number of units sold) - Total costs

Profit = ($120 * 240) - ($8,000 + $19,200)

Profit = $28,800 - $27,200

Profit = $1,600

By conducting a CVP analysis, we can determine the Break-Even Point, contribution margin, and analyze the profitability based on the given data.

The nucleus of an atom describes option A. It is the most massive part of an atom.

The nucleus is the central part of an atom and is composed of protons and neutrons. Protons have a positive charge, while neutrons have no charge (they are neutral). Electrons, on the other hand, are negatively charged particles that orbit the nucleus in electron shells. The nucleus is incredibly small compared to the overall size of the atom, but it contains most of the atom's mass.

The protons and neutrons within the nucleus contribute to the mass of the atom, while the electrons have a negligible mass in comparison. The mass of an atom is determined by the total number of protons and neutrons in the nucleus. Protons and neutrons have roughly the same mass, and their combined mass gives the atom its atomic mass.

Electrons, though they have mass, contribute very little to the overall mass of the atom. The nucleus also plays a critical role in determining the chemical properties and behavior of an atom. The number of protons in the nucleus determines the atomic number, which defines the element and its unique properties. Therefore, the correct answer is option A.

Under a stressful situation, the hypothalamus responds by sending signals to the pituitary gland and suprarenal gland to secrete adrenaline and noradrenaline to the bloodstream. The pituitary gland is the one that immediately activates.

The sympathetic nervous system, SNS, prepares the body for stressful situations that require an alert state or strength. It is responsible for the neural fight-or-flight response to stress.

The hypothalamus is in charge of stress responses. If the individual is exposed to a stressful situation, the hypothalamus sends signals to the pituitary gland and the adrenal medulla (suprarenal gland). The adrenal medulla secretes the neurotransmitters and hormones adrenaline and noradrenalin into the bloodstream. These hormones prepare the body for a stress response by increasing heart-biting frequency and strength, increasing blood pressure, stimulating respiration, and dilating respiratory tracts.

Once the threat factor is over, the body goes back to a balanced state.

When a person that is walking in the woods runs into a mother bear and her cubs, the gland that immediately activates is the pituitary gland and then the suprarenal gland.

Hardwired characteristics of the brain that attempt to keep us in balance by correcting deficiencies are referred to as homeostatic mechanisms.

Homeostasis is the body's ability to maintain a stable internal environment despite external changes.

In the context of the brain, homeostatic mechanisms involve various processes that regulate physiological functions and maintain optimal levels of essential substances.

These mechanisms can include feedback loops that detect imbalances and initiate corrective actions.

For example, if there is a deficiency in a particular nutrient or hormone, the brain may activate mechanisms to increase its production, decrease its consumption, or enhance its absorption from the environment.

Homeostatic mechanisms play a crucial role in ensuring the body's overall stability and functioning, helping to maintain proper levels of various substances and promoting overall well-being.

With this result, it was suggested that after millions of years of interacting organic molecules (olds and new ones) lipids and proteins would eventually arise. This experiment is not perfect, and has many assumptions (potentially drawbacks), but showed that organic compounds (the chemical basis of life) could emerge from quite simple components.

Transplant immunity causes rejection. When a transplant is performed, the immune system of the recipient recognizes the transplanted tissue as foreign and attempts to destroy it.

This response is called rejection, and it is an immune response against the transplanted tissue. There are two types of rejection: hyperacute rejection, which occurs almost immediately after transplantation and is due to pre-existing antibodies against the donor tissue, and acute rejection, which occurs within the first few months after transplantation and is a cell-mediated immune response against the donor tissue. Chronic rejection is a slow, progressive form of rejection that can occur over months or years after transplantation.
