Transmembrane proteins span the width of the cell membranes. Four types of transmembrane proteins are shown in a section of cell membrane.
groene
Although these proteins have different specific functions, they all-
A-stop chemical reactions within the cell
B-synthesize molecules that signal other cells
C- help the cell interact with its external environment
D- remove large waste particles from the cytoplasm of the cell
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.

how does matter move from the hydrosphere into the biosphere explain in your own words
Water mover form hydrosphere i.e river to biosphere i.e atmosphere by a process of evaporation.Thus, we can say that matter is move from hydrosphere to biosphere.
What is hydrosphere and biosphere?Hydrosphere:-
The hydrosphere is the collective mass of water which is found on under, or above the surface of earth. Although earth hydrosphere is 4 billions old. A planet's hydrosphere can be liquid, vapor or ice.
Biosphere:-
The region or area of surface where living organisms survive their life are called as biosphere. The biosphere is a narrow zone on the surface of the earth where soil, water, and air combine to survive life.
Evaporation:-
The process in which water or liquid converts into vapor is called as evaporation. In the case of water it starts vaporization at 100 degree C.
So, we can say that the conversion of matter from hydrosphere to biosphere is successfully achieved by evaporation.
Therefore, Water mover form hydrosphere i.e river to biosphere i.e atmosphere by a process of evaporation.Thus, we can say that matter is move from hydrosphere to biosphere.

What do the results of the agar blocks indicate about the relationship between cell size and time for materials to reach the center of the cell?
Include an explanation of how the surface area-to-volume ratio, diffusion rate, and time for substances to reach the center are related. Support your explanation with data.
PLZ HELP!!! 50 points!!!
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.

What is the elephant getting when the bond is broken in sucrose?
Answer:
Energy
Explanation:
The elephant is getting energy when the bond is broken into sucrose because as sucrose is broken down, it is hydrolized by enzymes sucrase which break the glycosidic bond and convert it to glucose and fructose in the upper gastrointestinal tracts. Glucose and fructose are then absorbed into the blood stream which glucose serve as energy source or stored as glycogen in the gastrointestinal tracts.

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).

Which best explains why the sun maintains its size and shape?
A. Pressure caused by high temperatures are balanced by gravity.
B. The sun burns from its core to its surface.
о
C. Forces exerted by orbiting planets cause the sun to rotate.
Answer:
A
Explanation:
The Suns own weight keeps itself together and keeps its size and shape. all things have gravity. in this case, the sun keeps it shape with balancing its gravity with the pressure.
The best explanation of why the sun maintains its size and shape is forces exerted by orbiting planets cause the sun to rotate. The correct option is C.
What is orbiting?"Orbiting" is one of those digital dating terms that perfectly describes what many of us have experienced but didn't realize had a name. It's when someone you were dating tells you they're no longer interested but keeps in touch with you on social media.
The Sun's own weight holds it together and maintains its size and shape. Everything has gravity. In this example, the sun maintains its shape by balancing gravity and pressure.
Planets orbit the sun in elliptical orbits, with the sun slightly off-center of each ellipse.
Therefore, the correct option is C. Forces exerted by orbiting planets cause the sun to rotate.

How is a hybrid different from its originating crops?
A hybrid crop is different from the original crops as they contain genes from other crops that are beneficial for them.
A hybrid has the genetic makeup of both of its parent crops but may have completely distinct external characteristics. This is due to the fact that two recessive genes from both parent crops can be fused together to create an outward visible impact in the hybrid.
Hybrid plants are the result of the cross-pollination of two plant varieties and the propagation of the seed resulting from the mix. The plant that emerges from this seed combination is known as a hybrid plant.

A population of 20 monarch butterfly is colonize a meadow. The meadows carrying capacity for a monarch butterfly's is 5000 individuals. What statement best describes the growth rate of the population of Monarch butterfly after the Meadow is colonized?
Answer:
D
Explanation:
A.
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.

Review why carbon can form a variety of organic compounds in a variety of shapes.
Answer:
Carbon atoms readily bond with each other and can form long chains, branched molecules, and rings—an enormous variety of carbon backbones for organic molecules.
Explanation:
Carbon atoms easily connect with one another, allowing for the formation of lengthy chains, branching molecules, and rings—a vast array of carbon backbones for organic molecules.
What is carbon?Carbon is defined as the elements are distinguished by their capacity to form firmly bound chains that are sealed off by hydrogen atoms.
Carbon is also defined as an atomic number 6 chemical element with the symbol C.
Carbon is nonmetallic and tetravalent, with each atom releasing four electrons to form covalent chemical connections.
Carbon has the capacity to quickly form bonds with other atoms, which allows for greater flexibility in the shape and function of biomolecules such as DNA and RNA, which are required for the defining traits of life growth and replication.
An organic molecule is defined as a complex molecule composed mostly of carbon atoms that are bound with other elements and/or other carbon atoms.
Carbohydrate, lipids, nucleic acid and protein are some of the example of organic molecules.
Thus, carbon atoms easily connect with one another, allowing for the formation of lengthy chains, branching molecules, and rings—a vast array of carbon backbones for organic molecules.

Why don’t we have a complete fossil record of all life that’s ever lived?
Answer:
Why don't we have a complete fossil record of all life that's ever lived? Fossil formation requires a rare mix of physical and biological conditions. Fossils must be exposed at Earth's surface to have a chance of being found. Fossils can be destroyed when rocks erode, melt, or change composition.
Explanation:
For many reasons, the fossil record is not complete. Most organisms decomposed or were eaten by scavengers after death. Many species lacked hard parts, which are much more likely to fossilize. Some rocks and the fossils they contained have eroded and disappeared.
Please mark me as the brainliest
Answer:
Sediment has to cover the bones in order for fossilization to take place

Orange trees planted in a grove or orchard would most likely fall in the even category of population distribution. The correct option is a.
What is population distribution?Population distribution is how the population of something, plants, animals, or humans is distributed in specific areas. It specifies where people live or where they are not living.
There are three types of population distribution:
Uniform dispersion - In this distribution, the population is uniformly or evenly distributed in the areas. Even distribution comes under this distribution.Random dispersion - there are no predictable patterns in this dispersion. They are randomly present anywhere.Clumped dispersion - This distribution shows the bunch or group of population is areas then there is no population, and then there is a a bunch of population in another place.Thus, the correct option is a. even.
