Which cross section best represents the valley shape where a rapidly flowing stream is cutting into the bedrock in a mountainous area

Answer:

This question lacks options, the options are:

A) Saliva converting the starch molecules in crackers into simple sugars

B) Digestive enzymes breaking down proteins into smaller fragments

C) bacteria converting lactose into simple sugars in the intestines

D) teeth grinding an almond into smaller pieces in the mouth

The answer is D

Explanation:

A physical change is a change that occurs to a substance without altering its chemical composition. A physical change involved a change in the substance's shape, texture, color, state etc. but not the chemical content of such substances.

In this question involving the processes that occur in digestion, a typical example of physical change is "teeth grinding an almond into smaller pieces in the mouth" because the teeth only changes the shape and texture of the almond. It does not affect the chemical composition of the almond fruit. This is also called mechanical digestion.

Note that, other options involving digestive enzymes breakdown are chemical changes because the enzymes breakdown the chemical components of each substance.

Answer: D

Explanation: because you are breaking down food in a physical change

Answer:

There is inverse relationship between cell size and time to reach the center.

Cell size has a inverse relationship with the time that the materials needed to reach the center of the cell because if the cell size increases more time is required for a material to reach to the center of the cell due to more distance between the center and boundary of the cell. The surface area-to-volume ratio, diffusion rate, and time for substances to reach the center are related to each other.

If the surface area to volume ratio is higher than more materials can diffuse across the membrane of the cell but more time is required to reach the center because increase in cell size leads to more distance between center and boundary of the cell so we can conclude that there is inverse relationship between cell size and time to reach the center.

Answer:

Exponential growth is the rapid growth of biological organisms. This usually happens when the amount of resources is unlimited in a habitat, therefore creating more and more organisms which increases population.

Explanation:

Answer:

See the answer below

Explanation:

Both water and glucose contain hydrogen and oxygen. However, glucose has carbon in addition to the two elements. A molecule of glucose has 6 carbon, 12 hydrogen, and 6 oxygen atoms while a molecule of water has just 2 atoms of hydrogen and one atom of oxygen.

Both glucose and water are polar molecules.

Water is liquid at room temperature while glucose is a solid at room temperature.

In terms of structures, the overall structure of water is bent while that of glucose may be alpha or beta 6 carbon ring structure.

Answer:

Both are formed when the groundwater gets heated

Explanation:

This is correctamundo

"why?"- you ask

well because when groundwater gets all hot and worked up we get a result in the form of geysers and hotsprings!

Have a great day and wash your hands and STOP TOUCHING YOUR FACE!

jk haha- please don't be take this seriously good day to you all!

Answer:

B. Both are formed when the groundwater gets heated.

Explanation:

Hot springs and geysers are very similar when it comes to how they are formed. The obvious difference is that geysers force up jets of water, whilst hot springs flow water out on their own. They are both formed when the groundwater gets heated from molten rock(magma).

This is reliable because I took the same quiz and got the question right.

Answer:

C. help the cell interact with its external environment

Explanation:

A transmembrane protein (TP) is a type of integral membrane protein that spans the entirety of the cell membrane. Many transmembrane proteins function as gateways to permit the transport of specific substances across the membrane.

Although transmembrane proteins have different specific functions, they always HELP the cell interact with its external environment.

Transmembrane proteins are a broad category of membrane proteins that act as carriers and/or transporters in order to allow the movement of specific substances across cell membranes.

After binding to their specific ligands, the three-dimensional (3D) shape of transmembrane proteins changes in order to allow the movement of molecules and ions through the cell membrane.

For example, aquaporins are a type of transmembrane protein that regulates the entry of water (H2O) molecules into and out of cells.

In conclusion, although transmembrane proteins have different specific functions, they always HELP the cell interact with its external environment.

The population grows exponentially until it approaches 5,000 individuals, and then the population size begins to decrease.

B.

The population grows exponentially until it approaches 5,000 individuals, and then its growth rate decreases.

C.

The population grows at a constant rate until it approaches 5,000 individuals, and then its growth rate increases.

D.

The population grows at a constant rate until it approaches 5,000 individuals, and then the population size remains stable.

The statement that best described the growth rate of the Monarch butterfly after the Meadow was colonized would be that the population grows at a constant rate until it approaches 5,000 individuals, and then the population size remains stable.

The carrying capacity generally represents the maximum number of individuals of a particular species an environment can support based on the resources that the environment has. Ideally, the population only stabilizes with very minimal oscillation around the carrying capacity. It neither decreases nor increases significantly unless a major disruption happens.

The only option that addresses the stability of populations around the carrying capacity of the environment is option D.

The correct answer is D.
