The cell membrane (plasma membrane) is describe as a highly selective barrier composed of a lipid bi-layer. This structure plays an important role in moving molecules across the cell membrane in order for the cell to maintain homeostasis. If the cell is unable to take in the materials it needs or remove what it does not need, the cell may die. This inability of cells to maintain homeostasis may cause sickness or even death of an organism. Why is it important that the cell membrane is highly selective?
Answer:
Selective permeability is a property of cellular membranes that only allows certain molecules to enter or exit the cell. This is important for the cell to maintain its internal order irrespective of the changes to the environment. ... Movement across a selectively permeable membrane can occur actively or passively
Explanation:
The cell membrane is highly selective in order to prevent certain ions/molecules from entering or exiting the cell. This feature is fundamental for maintaining the homeostasis of the cell.
The homeostasis of the cell refers to the internal balance that cells must have to carry out their metabolic functions (e.g., reproduction, growth, differentiation, etc).The cell membrane is a highly selective lipid bilayer due substances do not cross it indiscriminately but instead it allows the entry/exit of specific particles into the cell.There are some substances that can move across the cell membrane in favor of a concentration gradient (passive transport) and others that move against a concentration gradient (active transport).In conclusion, the cell membrane is highly selective in order to prevent certain ions/molecules from entering or exiting the cell.

gravity,friction and motion
The forces of nature that affect our daily/monthly/seasonal basis include weather, gravity, and the rotation and revolution of the Earth, which affect the temperature, precipitation, and daylight hours.
What are the forces of nature?The forces of nature refers to the fundamental forces that govern the behavior and interactions of matter and energy in the universe. The four known fundamental forces of nature are:
-Gravity: the force that attracts two objects towards each other proportional to their mass.
-Electromagnetism: the force that governs the behavior of charged particles and the interaction of electric and magnetic fields.
-The Strong Nuclear Force: the force that holds the protons and neutrons together in the nucleus of an atom.
-The Weak Nuclear Force: the force responsible for certain types of radioactive decay.
These forces are fundamental in the sense that they cannot be broken down into simpler components. They are also different from the forces that we experience in our daily lives, such as friction or tension.

A caterpillar has an exoskeleton and feeds on many leaves before it makes a cocoon and becomes a butterfly. Which type of organism is a caterpillar? an autotroph and an invertebrate a heterotroph and an invertebrate an autotroph and a vertebrate a heterotroph and a vertebrate
Answer:
heterotroph and an invertebrate
Explanation:
Animals have been classified into being AUTOTROPHIC OR HETEROTROPHIC based on their nutrition while they are also classified as VERTEBRATE OR INVERTEBRATES based on their skeleton. A heterotrophic animal is one which depends on other organisms to obtain energy or food while an invertebrate is an animal that lacks a vertebrae column or backbone.
In this case, caterpillars are said to feed on many leaves before it makes a cocoon and becomes a butterfly. This means it relies on plants (leaves) for food, hence, it is HETEROTROPHIC. Also, it has an exoskeleton i.e. skeleton present outside the body. This means that it does not possess any bone inside to form the backbone, and hence it is an INVERTEBRATE.

Level 5: A rancher buys a brown bull with curved horns, but needs to know the bull's genotype for breeding purposes. He knows that brown is dominant to black in these cows. 1: How can the rancher determine (find) the genotype of this bull? 2: What other information does the rancher need, if any, to determine the bull's genotype?
Answer:
Explanation:
1. Since brown is dominant to black, in order for the farmer to determine the genotype of the brown bull, he will need to test-cross the bull with a black bull. The phenotypes of the offspring from the testcross will determine whether the brown bull is a true-breeding one or a heterozygous one.
If all the offspring from the testcross are brown, it means the bull is a true-breeding brown. If the offspring is a mix of brown and black, it means the bull is heterozygous for the brown genotype.
To further illustrate the explanation, let us assume that the brown allele is B and the black allele is b. B is dominant over b, hence, a brown bull can BB or Bb while a black bull can only be bb.
The rancher is not sure if the bull he bought is BB or Bb, hence, he needs to testcross with another bull that is bb. Assuming that the rancher's bull is BB
BB x bb
Bb Bb Bb Bb (all brown)
Assuming the rancher's bull is Bb
Bb x bb
Bb Bb bb bb (50% brown, 50% black)
2. All the information that the rancher needs have been explained above. No other information is needed
If two players push against each other with 30 N of force and no yardage is gained or lost, what is the net force?
Answer:
its 30 N
since it didn't change it stays the same 30N.
Since the forces are in opposite direction to each, the net force of the two players is equal to zero Newton.
If two players push against each other with 30 N of force, That is, player 1 exert 30 N of force on player 2 while player 2 also exert 30 N of force on player 1 and no yardage is gained or lost.
Force is a vector quantity, that is, we will consider both the magnitude and direction. The resultant or net force of the two players can be expressed as:
Net Force = Player 1 force - Player 2 force
Net force = 30 - 30
Net force = 0
Since the forces are in opposite direction to each others and they are also of the same magnitude without any gain or loss of energy, the two forces will counterbalance each other.
Therefore, the net force of the two players is equal to zero Newton.

Explore: Use the Gizmo to create three more carbon paths, each starting and ending in the atmosphere. Label each location with A for atmosphere, B for biosphere, G for geosphere, or H for hydrosphere. (You can also use P for anthroposphere if you like, or just include it in the biosphere.)
path 1
path 2
path 3
Answer:
The answer is below
Explanation:
1. Path A (Atmosphere) :
Carbon Path: Atmospheric CO2: this arises from geological sources such as volcanoes, burning fossil fuels, etc. This gets carbon dioxide back into the atmosphere during these processes.
2. Path G (Geosphere)
Carbon Path: Lithosphere: Earth’s carbon has been researched to have large limestone deposits. This limestone can be found in the Earth's lithosphere. Through the heating of limestone, carbon dioxide gets back to the atmosphere.
3. Path H (Hydrosphere)
Carbon Path: Oceania CO2: there is a large deposit of dissolved CO2 underneath the ocean. As the ocean gets colder, it dissolves more. The plants absorbed carbon dioxide through photosynthesis and get back to the atmosphere
The earth's atmosphere has layers: the exosphere, thermosphere, mesosphere, stratosphere, and troposphere from highest to lowest levels.
These layers are composed of Nitrogen, oxygen, other gases and are defined by unique characteristics of temperature and pressure.
1. Path A (Atmosphere)
The carbon path in this layer involves atmospheric carbon dioxide. The burning of fossil fuels like petrol, coal, diesel, volcanic explosions and wildfires brings back the carbon dioxide in the atmosphere during these processes.
2. Path G (Geosphere)
The carbon path involves the lithosphere. Expiration by plant and animal, burning of carbonate rocks like limestone, shale gas and coal release carbon which get backs in the atmosphere.
3. Path H (Hydrosphere)
The carbon path involves oceanic carbon dioxide. Ocean and water bodies have enormous amounts of dissolved carbon in them. Aquatic plants use this diffused carbon dioxide and free it back into the atmosphere.

How does the amount of a rocket's thrust affect its trajectory? What does it take for an orbiting spacecraft to escape its orbit? If you were to plan a mission to Mars, what are the key phases that you need to include in your mission?
Answer:
Thrust helps to move the rocket against gravity.
Explanation:
The amount of a rocket's thrust affect its trajectory because this thrust help the rocket to move against the gravity of the earth. More force in the form of thrust is needed by orbiting spacecraft to escape its orbit because the orbit does not allow the orbiting spacecraft to escape so for that force is needed to to against its orbit. First, we need to escape from the gravity of earth then go towards the mars. after entering the gravity of mass, we used a force which helps in safe landing on the mars.
