How do catalysts affect a chemical reaction?
A. increase the activation energy
B.provide activation energy
C. lower activation energy
D. lose activation energy
Answer:
C: Lowering activation energy
Explanation:
A catalyst speeds up a chemical reaction, without being consumed by the reaction. It increases the reaction rate by lowering the activation energy for a reaction.
What would happen to an animal cell with an internal salt concentration of 70% if it were placed in a salt solution with a concentration of 20%? Why?
Answer:
It will swell and eventually burst because water from the environment is flowing into the cell
Explanation:
This question is describing OSMOSIS, which is the movement of water from a region of high concentration to a region of low concentration across a semi-permeable membrane. The osmotic process is facilitated by the formation of an OSMOTIC GRADIENT i.e. difference in concentration between the two sides of the membrane.
In this case, an animal cell containing an internal salt concentration of 70% (hypertonic) were placed in a salt solution with a concentration of 20% (hypotonic), OSMOSIS will occur in the sense that water will move from where it is more concentrated (salt solution) into where it is less concentrated (animal cell), hence, the animal cell will SWELL AND EVENTUALLY BURST.

Which of the following required a protein channel (carrier) to allow molecules to cross the cell membrane (plasma membrane)? (Hint: multiple answers)
A. facilitated diffusion
B. osmosis
C. active transport
D. diffusion
Answer:
the answer would be c
Explanation:
The process that entails the movement of protein channel (carrier) through cell membrane (plasma membrane) as regards this question is C. active transport
Active transport can be regarded as a process involving the movement of molecules through the cellular membrane using cellular energy. Active transport is utilized by cells for accumulation of needed molecules. These molecules could be glucose as well as amino acids.Therefore, option C is correct.

This is my GCSC revision! IN DETAIL PLS describe how microbes reproduce!!
Explanation:
Bacteria grow to a fixed size and then reproduce through binary fission which a form of asexual reproduction. Under optimal conditions, bacteria can grow and divide extremely rapidly. Different kinds of bacteria need different amounts of oxygen to survive. that's all I know sorry :(

Explain how transmission,
absorption, and reflection
cause objects to be
transparent, translucent, or
opaque?
Answer:
Transparency is caused by the transmission of light waves. If the vibrational energy of a light wave is passed through the object, then the object appears clear, or transparent. If the energy only causes vibrations in the surface before reflecting off the object, then the object appears opaque.

Task 2: The Circulatory system pumps blood and oxygen to all of the organs in your body to keep them working, The respiratory system takes in oxygen and the circulatory system takes that oxygen to all parts of the body. The circulatory system also takes nutrients from food that is digested by the digestive system to all parts of the body to keep them working as well.
Task 3: The Endocrine system is important to controlling the human body but for these reasons I believe that the nervous system is more important. I think that the Nervous system is more important to controlling functions and processes in the human body because without the nervous system messages from and to your brain can not be relayed. Without the nervous system you would not be able to move or feel pain when you have been injured.
which human activity can have the greatest positive effect on the global climate change by helping to reduce the amount of carbon dioxide in the atmosphere?
Answer: I cant see D but the answer is B
Recycling plastics to manufacture materials. Therefore, option (B) is correct.
Transitioning to renewable energy sources offers the greatest potential to reduce CO2 emissions and mitigate climate change globally. Solar, wind, and hydropower can greatly cut CO2 emissions from electricity generation. Building, transportation, and industrial energy efficiency can reduce carbon emissions further.
Recycling plastics reduces climate change. Recycling plastic waste reduces energy-intensive and CO2-emitting plastic production. Recycling plastic reduces demand for fossil fuel-derived raw materials used in plastic manufacturing, indirectly reducing carbon emissions.

1. List how a cell transports across the membrane?
2. What are the types of passive transport?
3. Describe what is facilitated diffusion?
Answer:
1. this process continues until the substance is evenly distributed in a system.
2. depends on the cell membrane!
3. Facilitated diffusion is the diffusion of solutes through transport proteins in the plasma membrane.
Explanation:
1. The passive forms of transport, diffusion and osmosis, move materials of small molecular weight across membranes. Substances diffuse from areas of high concentration to areas of lower concentration
2. passive transport depends on the permeability of the cell membrane, which, in turn, depends on the organization and characteristics of the membrane lipids and proteins. The four main kinds of passive transport are simple diffusion, facilitated diffusion, filtration, and/or osmosis.
3. Facilitated diffusion is a type of passive transport. Even though facilitated diffusion involves transport proteins, it is still passive transport because the solute is moving down the concentration gradient
