Explanation:
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.
Answers
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.

Many processes occur in the digestive system .which process is best classified as a physical change
Answers
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
Which occurs during digestion?
O The mouth only allows for physical digestion,
O The mouth only allows for chemical digestion.
O Chemical digestion prepares the food for physical digestion.
O Physical digestion prepares the food for chemical digestion.

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
Answers
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 is a hybrid different from its originating crops?
Answers
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?
Answers
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.

c.clumped
d. density
Answers
Answer:
A) Even
Explanation:
got it right on edge :)
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.
