What causes the phases of the moon ?

Answer:

Its isotonic

Explanation:

Because The contact lenses that we wear have been formulated to be isotonic, which means that they have the same osmotic pressure as the tear film in our eye.

Contact lens solution is salty in order to match your tears, which is isotonic to the cells in the eyes. The correct option is C.

Isotonic solutions have the same osmolarity (or solute concentration) as other solutions.

Water will flow in equal parts out of each solution and into the other if these two solutions are separated by a semipermeable membrane.

Isotonic solutions are used to increase fluid volume due to blood loss, surgery, dehydration, and extracellular fluid loss.

The contact lenses we wear are isotonic, which means they have the same osmotic pressure as the tear film in our eye's layer of lubricant bathing the cornea and conjunctiva.

The ocular tissues and the water in the lens must maintain equilibrium.

Thus, the correct option is C.

Answer:

Valency is the combining power of an element. Elements in the same group of the periodic table have the same valency. The valency of an element is related to how many electrons are in the outer shell.

Explanation:

Explanation:

Valency is the measure of the combining capacity of elements to form compounds. The valency of an element depends on the number of valence electrons in its atom because valence electrons take part in a chemical reaction. The valency of an element is either equal to the number of valence electrons in its atom or equal to the number of electrons required to complete 8 electrons in the valence shell. Hence , we can define Valency as the combining capacity of an element or the radical with the other element or radical to form molecule or a compound.

Convective clouds cannot go high enough to produce showers and visibility also greatly reduced due to the accumulation of dust and smoke particles.

Frontal Inversions are the inversions that is caused by a shallow "cold air" blowing in under warmer air. An inversion traps air pollutants, such as smog, close to the ground.

So we can conclude that convective clouds cannot go high enough to produce showers and visibility also greatly reduced due to the accumulation of dust and smoke particles.

The virus infections happens when a virus gets past the physical barriers of the body (skin, mucus, and so on) and infect a suitable cell, the virus take the genetic machinery of the host cell to replicate, damaging that cell and making more virus that will do the same process with other suitable cells. After the virus use all the cell potential, it will kill the cell and release all the virus that were in the cytoplasm of the host. While bacterial infections have more autonomy, being not necessary the integral machinery of the cell to multiply in the host body, it can act in differrebt ways, such as: crowd out the host tissue and disrupt the function, killing the cells or tissues outright, destroy the metabolic machinery, cause a massive toxic reaction in the immune system, and release toxins that can make the body stop all their functions at once (paralyze the metabolic and general system of the host).

A hypothesis is hard to be considered "falsified" because it is based on the knowledge that you have and you are making a presumption based on a set of data and then working to prove and backup the hypothesis which could potentially be wrong but isn't falisfied as it is your own conclusion an not a statement    

The basic chromosome number of a hexaploid species with 42 chromosomes is 7 (option d).

A hexaploid species has six copies of each chromosome, which is represented by the term 6x, where x is the basic chromosome number. To determine the basic chromosome number, you can divide the total number of chromosomes (42) by the ploidy level (6). So, 42 ÷ 6 = 7.

This means that the hexaploid species has seven unique chromosomes, each present in six copies, making a total of 42 chromosomes.  It's important to note that different species can have different basic chromosome numbers. Hence, d is the correct option.

The trace mineral that is an essential component of thyroid hormones is iodine, option B is correct.

Iodine plays a crucial role in the synthesis of thyroid hormones, including thyroxine \((T_4)\) and triiodothyronine \((T_3)\), which are responsible for regulating the body's metabolism. These hormones are produced by the thyroid gland and require iodine to be incorporated into their structure.

Without adequate iodine, the thyroid gland cannot produce enough hormones, leading to a condition known as iodine deficiency disorder (IDD). IDD can result in impaired growth and development, goiter (enlargement of the thyroid gland), and cognitive impairment. Therefore, ensuring sufficient intake of iodine through diet or supplementation is vital for maintaining optimal thyroid function and overall health, option B is correct.

Scale of the model: 1:10,000. To find the scale of the model, we need to compare the size of the model to the actual size of the red blood cell. Given that the diameter of the red blood cell is 0.008mm and the diameter of the model is 80mm, we can calculate the scale by dividing the diameter of the model by the diameter of the actual cell.

Scale = Model diameter / Actual cell diameter

Substituting the given values:

Scale = 80mm / 0.008mm

Simplifying the expression:

Scale = 10,000

Therefore, the scale of the model is 1:10,000.

1. Identify the diameter of the red blood cell: 0.008mm.

2. Identify the diameter of the model: 80mm.

3. Use the formula Scale = Model diameter / Actual cell diameter.

Explanation:

The mid-atlantic ridge is a divergent plate boundary.

A divergent plate boundary is a type of tectonic boundary where two lithospheric plates move away from each other. This movement creates a gap or rift between the plates, leading to the formation of new crust through volcanic activity and the upwelling of molten material from the Earth's mantle.

The mid-atlantic ridge is a prime example of a divergent plate boundary. It runs down the middle of the Atlantic Ocean, separating the North American plate from the Eurasian plate.

As the plates move apart, magma rises to fill the gap, resulting in volcanic activity and the formation of new crust. This process contributes to the widening of the Atlantic Ocean over geological time.

The other options listed are not examples of divergent plate boundaries. The Andes Mountains (option A) are formed by a convergent plate boundary, where two plates collide, typically resulting in mountain building and subduction zones.

Emphysema is a severe form of COPD that can lead to several serious complications, such as alveolar wall breakdown, reduced respiratory membrane surface area and gas exchange, increased vital capacity, hypoxemia, hypercapnia, and respiratory acidosis, and polycythemia Cor pulmonale.

Emphysema is a chronic obstructive pulmonary disease (COPD) that is characterized by the destruction of the alveolar walls and a reduction in the surface area available for gas exchange.

As a result, individuals with emphysema may experience a decrease in vital capacity, which is the amount of air that can be expelled from the lungs after a deep inhalation.One of the most common complications of emphysema is hypoxemia, which is a condition in which the body does not receive enough oxygen.

This can lead to hypercapnia, a condition in which there is too much carbon dioxide in the blood, and respiratory acidosis, a condition in which the blood becomes too acidic. Another complication of emphysema is polycythemia, which is an increase in the number of red blood cells. This can occur as the body tries to compensate for the lack of oxygen by producing more red blood cells to carry oxygen to the body's tissues.
