Mechanical Digestion is a type of digestion for which the teeth in the mouth are responsible. It consists of chewing the food.

Answer:

dont question the impossible

Explanation:

Answer:

The answer is below

Explanation:

Let m be the mass of each of lead-206 and uranium-238 found in the rock. The radioactive decay is given as:

[tex]U_t=U_oe^{-\lambda t}\\\\U_t=number\ of\ undecayed\ U238\ after\ time \t,\\U_o=number\ of\ undecayed\ U238\ initially,\lambda=decay\ constant\\\\But\ U_o=U_t+Pb_t\\\\U_t=U_t+Pb_t(e^{-\lambda t})\\\\e^{-\lambda t}=\frac{U_t}{U_t+Pb_t} \\\\e^{\lambda t}=\frac{U_t+Pb_t}{U_t} \\\\e^{\lambda t}=1+\frac{Pb_t}{U_t}[/tex]

half life of uranium-238 = 4.468 * 10⁹ years

λ = 0.693 / half life = 0.693 / 4.468 * 10⁹ years = 0.1551 * 10⁻⁹

[tex]n_{Pb_t}=\frac{m}{206} \\\\n_{U_t}=\frac{m}{238}\\\\1+\frac{\frac{m}{206}}{\frac{m}{238}}=e^{\lambda t} \\\\e^{\lambda t} =2.1553\\\\ln(e^{\lambda t} )=ln(2.1553)\\\\\lambda t=0.7679\\\\t=\frac{0.7679}{\lambda} \\\\t=\frac{0.7679}{0.1551*10^{-9}} \\\\t=3.43*10^9\ years[/tex]

Answer:

Soils are composed of mixtures of mineral and organic materials, but are classified according to the size of their mineral particles. The three main texture groups are sandy, silty, and clay.

Sandy soil contains particles that can be seen with the naked eye and feels gritty when rubbed between the thumb and forefinger. Sandy soils will generally not stick together when wet.

Silty soil contains particles, which are smaller than sand particles but larger than clay particles. Silt feels powdery when rubbed between the thumb and forefinger. Silty soil sticks together when wet, but will not hold its shape after it is dry.

Clay soil contains the smallest particle size. Clay particles form a sticky soil when wet and will generally hold a shape after drying. Soils are rarely composed of just sand, silt, or clay. They are usually a mixture of the three with a larger percentage of one size of particles.

Answer:  

Depending upon the average grain-size and the conditions under which soils are formed and deposited in their natural state, they may be categorized into following types on the basis of their structure: In the grain-size classification, soils are designated according to the grain-size or particle-size. The more common classification systems are enlisted below: Geological Classification

Classification by Structure

Classification based on Grain-size

Unified Soil Classification System

Preliminary Classification by soil types

Based on the agencies responsible for their present state, soils may be classified under following types:  Residual Soils

Transported Soils:

Alluvial or sedimentary soils

Aeolian soils

Glacial soils

Lacustrine soils

Marine soils.

Then you have inorganic and organic soils.

Answer: the amount of protein produced

Explanation: a dominant gene produces enough of its protein to become a signiture trait even if it is paired with a recessive trait but with two or more reccesive traits your body is getting a low amount or no amount of the protein needed to become/show up as a dominant trait

Rivers in the area weather and erode the land, forming a mouth in this area.

It is the place where a stream of water, such as a river, empties. Thus, a river can have as its mouth another river, a large lake, a pond, a sea or the ocean.

With this information, we can conclude that the rivers in the area weather and corrode the land, forming a mouth in this area.

Answer:

False

Explanation:

Pluripotent stem cells are master cells. They're able to make cells from all three basic body layers, so they can potentially produce any cell or tissue the body needs to repair itself.

Pluripotent stem cells have the ability to undergo self-renewal and to give rise to all cells of the tissues of the body (but not the placenta).

Terms included in the Koppen-Geiger scale classification are: humidity and precipitation, and local native plant life.

The Koppen climate classification is a classification created in 1884 in which the different types of climate are described and associated with a series of letters, usually three, that indicate the behavior of temperatures and precipitation.

Additionally, this system is based on the natural vegetation of different parts of the world because this factor is related to climate, especially the limits between one climate and another.

According to the above, it can be inferred that the correct terms are: humidity and precipitation, and local native plant life.

Answer:

Insects are protected by a chitin exoskeleton. The Venus flytrap cracks this protective shell using special digestion enzymes that are produced once the sensory hairs register a stimulus. It will ebb away if the hairs are not further stimulated.

Answer:

I do believe that the Venus flytrap is a predator because it is a carnivorous plant.  The plant's trap is a single large leaf with trigger hairs.

Explanation:

All of the following are functions of proteins except insulation. So, the correct option is (D).

Proteins are defined as large biomolecules and macromolecules consisting of one or more long chains of amino acid residues. Proteins do most of the work in cells and are essential for the structure, function, and regulation of the body's tissues and organs.

Proteins serve as the building blocks for bones, muscles, cartilage, skin and blood which also form the blocks for enzymes, hormones and vitamins. Proteins are one of the three nutrients that provide calories while the others are fats and carbohydrates.

Proteins function are storage, movement, structure, etc.

Thus, all of the following are functions of proteins except insulation. So, the correct option is (D).
