Because people make new scientific discoveries all the time.  We don't know everything.  We can only explain things in terms of what knowledge we have.

<span>Science knowledge relies on experimental and observational confirmation. Where data is incomplete, new or improved data may well lead to revision of accepted science explanations. In situations where observations are fragmentary, it is normal for scientific ideas to be incomplete, but this is also where the opportunity for making advances may be the greatest.The core ideas of science have been subjected to a wide variety of confirmations and are therefore unlikely to change in the areas in which they have been tested. </span><span>Science knowledge may change due to the development of new techniques for observing investigations (including new technologies), and also through new ways of thinking or framing the questions asked.</span>

Given that a virus divides every 3 hours, and that a cell lyses (explodes) after it reaches a viral load of 5,000,000 units, how
vladimir2022 [97]

The replication time for a virus starting at 1,500 units to lyse the cell is 5 hours.

<h3>How to calculate the Exponential growth/decay formula?</h3>

x ( t ) = x 0 × (1 + r ) t

  • x(t) is the value at time t.

  • x 0 is the initial value at time t = 0.

  • r is the growth rate when r/ 0 or decay rate when r < 0, in percentage.

  • t is the time in discrete intervals and selected time units.

Whit this information, we can conclude that the replication time for a virus starting at 1,500 units to lyse the cell is 5 hours.

The average radius of a molecule of lysozyme, and enzyme in tears, is 1430 pm. what is the radius in nanometers?
Galina-37 [17]

The average radius of a molecule of Iysozyme, an enzyme in tears, is 1430 pm.

The size of an element's nucleus and also the total number of electrons around it grow with an element's atomic number. The radius of an atom increases with increasing atomic number.

The calculation of conversion of radius is shown below:

It is known that, 1 meter is equal to 10¹² picometers.

We can use a conversion fraction to convert 1430 picometers to meters.

1430 pm × (1 m / 10¹² pm) = 1.430 × 10⁻⁹ m

1 meter is equal to 10⁹ nanometers.

Now, use a conversion fraction to convert 1.430 × 10⁻⁹ meters to nanometers.

1.430 × 10⁻⁹ m × (10⁹ nm/1 m) = 1.430 nm

Therefore, the radius of nanometers will be 1.430nm

Gemiola [76]

Answer:

Both statements are true.

Explanation:

The simple columnar epithelium is characterized by presenting a single layer of cylindrical cells, with the basal and oval nucleus. This type of epithelium is found throughout the entire digestive epithelium, mainly on surfaces with high absorption power such as the walls of the small intestine, but they are also found on secretory surfaces such as the stomach walls, in the gallbladder, in some sections of the collecting tubes of the kidney, in the uterine tube (where it is ciliated) and in the uterus itself.

Squamous Stratified Epithelium is made up of basal cells that are cuboidal or columnar and metabolically active and superficial cells are flattened (squamous). Its function is to protect the underlying tissues in areas subject to nuclei abrasion, this epithelium (not keratinized) forms the wet surfaces of the basal esophagus, oral cavity and vagina. The oropharynx and the pharynx itself are lined by a stratified squamous epithelium as well.
