how could large molecules cross the cell mebrane
Answers
Answer:
When molecules are too large or too charged to cross the plasma membrane by diffusion or osmosis, there are other methods to accomplish their transport into or out of the cell. For example, some proteins in the plasma membrane are known as protein channels and they form a way for large or charged molecules to pass through the membrane.
Explanation:
Answer:
through carrier or channel proteins

Will want to explore these changes in more depth, so we compare two kinds of ways matter changes and how they differ. He recorded his phonics in a science notebook. What are the ways in which matter changes, and how do they differ?
Answers
Answer: There are two types of change in matter: physical change and chemical change.
Explanation:
As the names suggest, physical changes never change the identity of the matter, only its size, shape or state. In a physical change, atoms are not rearranged and the matter's physical and chemical properties are unchanged.
to learn more about matter and how it changes take a look at this website:

Answers
Answer:
A Root
Explanation:
Plants have a root system, a stem or trunk, branches, leaves, and reproductive structures (sometimes flowers, sometimes cones or spores, and so on). Most plants are vascular, which means they have a system of tubules inside them that carry nutrients around the plant.
Roots anchor the plants in the soil and absorb nutrients and water that are needed by the rest of the plant.

Matter continuously cycles between the living and nonliving parts of an ecosystem. The flow of energy drives the cycling of matter through ecosystems.
The water, carbon, and nitrogen cycles share patterns in the flow of matter and energy through ecosystems. Describe two different patterns that can be observed in all three cycles.
NEEEEEEDDD THE ANSWER PLSSSSSSSS NOWWWWW
Answers
death and feeding process
Water, carbon and nitrogen cycles are biogeochemical cycles that exist in the biosphere to maintain a balance in the flow of energy and matter.
What patterns are observed in the cycles?There are three major biogeochemical cycles - water, nitrogen and carbon - that exist in nature which allow the transfer of matter and energy between the living and non-living things of the biosphere.
All the three cycles involve the exchange of gases from the plants to atmosphere to the animals or microbiota, which is again released back into the atmosphere.
Plants absorb the nitrogen, carbon and water in different forms from the environment which is then passed on.
Another similar pattern seen amongst the three is that humans release carbon, nitrogen and oxygen in various forms.

Look at the diagram of the rock cycle below.
Which part of the cycle is missing?
A.

C.

D.
mineral integration
Answers
it’s melting
From the diagram of the rock cycle the missing part is ( B ) ; Melting
Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.
Magma is released to the earth surfaces during volcanoes therefore the missing term in the rock cycle is melting
Hence we can conclude that from the diagram of the rock cycle the missing part is Melting.

CAN SOMEONE WRITE ME A PARAGRAPH ABOUT ENERGY
PARAGRAPH 1:
What is energy? Why is energy important? Describe at least two forms of energy.
PARAGRAPH 2:
What is thermal energy? Describe how thermal energy can move between objects and in what direction (hot to cold or cold to hot) . Include at least one example of how thermal energy moves.
Do NOT make a list. Write it as a paragraph!
A complete response to the writing prompt is 2 paragraphs. Each paragraph must include at least 3 sentences in order for you to receive credit.
Answers
Answer:
energy is something that must be transferred to a physical medium . there are multiple types of energy. kinetic energy thermal energy potential energy and solar energy to name a few. kinetic energy is a type of energy dealing with motion thermal energy deals with heat and potential energy is the amount of energy a object has relative to the stressed within its self like an arrow drawn back but hasn't been released yet
thermal energy presents its self as heat . like if you set hot coffee of a table for a few hours the energy will slowly begin to transfer to the air around it making the coffee cold but the room is significantly larger than the coffee cup so the transfer of heat goes undetected
Explanation:
Chemical, electrical, radiant, mechanical, thermal, and nuclear energy are the six main types of energy. Additional forms including electrochemical, acoustic, electromagnetic, and others might be addressed in other studies.
What are the different form of energy?Transferring energy into a tangible medium is necessary. Energy comes in a variety of forms. Solar energy, kinetic energy, thermal energy, and potential energy are a few examples.
Thermal energy deals with heat, kinetic energy deals with motion, and potential energy is the quantity of energy.
If necessary, the reaction can obtain this energy without exerting any effort. Enthalpy and the system's product of temperature and entropy are added to determine the change in Gibb's free energy.
Therefore, An object is strained relative to itself, like an arrow that hasn't been released yet after being drawn back.
