Passive transport into cells is driven by a concentration gradient; a greater concentration of molecules on one side of the membrane.
Which direction would oxygen move across a cell membrane if there was a greater concentration of oxygen molecules on the inside of the
membrane?
A. It would continue to concentrate inside the cell.
B. The random diffusion of oxygen would balance and have no net effect.
C. Towards the outside of the cell.
D. None of the above.
Answer:
A. It will continue to concentrate inside the cell.
Explanation:
Due to the higher concentration of oxygen molecules on the inside, oxygen molecules of the outside move to the inside and the more the oxygen molecules move inside the higher the concentration of the oxygen molecules on the inside.
Answer:
A
Explanation:
Towards the outside of the cell.

Answer:
The defining feature of a eukaryotic cell is the presence of a nucleus. Most animals and plants have eukaryotic cells.
Explanation:
Eukaryotic cells have a nucleus, and membrane-bound organelles All multicellular organisms are made up of eukaryote cells
Eukaryotic cells are one of the two types of cell types prokaryotic and eukaryotic. There are various structural and functional differences found in them.
Eukaryotic cells are defined by:
the presence of a nucleus enclosed by a complex nuclear membranepresence of membrane-bound organellescell wall may or may not be presentcell division is mitosis or meiosisEukaryotic organisms have various range of organisms including mostly all multicellular such as animals, plants, fungi, and protists, as well as most algae.

1- state the type of protein used in the immune system that is produced from amino acids by lymphocytes ?
Answer:
antibodies - proteins (gamma globulins)
Explanation:
The ribosome, a biological component found in the cytoplasm of cells, is in charge of producing luciferase.
what is cytoplasm:
The ribosomes are responsible for producing all proteins.The cytoplasm of a cell contains ribosomes, which are cell organelles that allow mRNA and tRNA to function so that proteins can be produced.All of the components of a eukaryotic cell outside of the cell nucleus are referred to as cytoplasm in cell biology. Nucleoplasm is the name for the substance that makes up the nucleus and is enclosed within the nuclear membrane. The cytosol, a gel-like fluid, the organelles, and numerous cytoplasmic inclusions are the three primary elements of the cytoplasm. About 80% of the cytoplasm contains water, and it is typically colorless.After removing the cell organelles and particles, groundplasm—a submicroscopic ground cell material or cytoplasmic matrix—remains. The bigger organelles, including ribosomes, mitochondria, plant plastids, lipid droplets, and vacuoles, are suspended in this highly intricate, polyphasic structure known as the hyaloplasm of light microscopy.The majority of cellular functions, including several metabolic pathways, including glycolysis, and procedures like cell division, take place within the cytoplasm. The concentrated inner region is known as the endoplasm, and the cell cortex or ectoplasm is the name of the outside layer.This is so that codons can be inserted, amino acids can be formed, and all the proteins, including luciferase, can be formed. The ribosome traps the mRNA molecule and moves over it.

which statement below correctly describes the process of glycolysis?
A. Glucose is broken down into two pyruvate molecules
B. Oxygen and glucose are broken down
C. Two pyruvate molecules are brown down into glucose
D. Glucose is broken down into ATP
Answer:
A)glucose is broken down into two pyruvate molecules
The statement below correctly describes the process of glycolysis, glucose is broken down into two pyruvate molecules. The correct option is A.
What is glycolysis?Glycolysis is the process in which glucose is broken down to produce two molecules of pyruvic acid, which also releases energy. This process can be carried out without the help of oxygen, thus an anaerobic reaction. This process is carried out in the cytoplasm.
For the cell to use as energy, glycolysis results in a net gain of two pyruvate molecules, two ATP molecules, and two NADH molecules. Following the conversion of glucose to pyruvate, the Krebs Cycle is connected to the glycolysis pathway, where additional ATP will be produced to meet the energy requirements of the cell.
Therefore, the correct option is A.

What is RNA polymerase?RNA polymerase is an enzyme that aids in the transcription of DNA into RNA during transcript in the nucleus. The enzymes prevent many genetic mutations from being expressed.
Primase is an enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis during replication as the DNA polymerases cannot begin the synthesis of the new strand, they only extend it after primase begins it and primase produces RNA molecules, the enzyme can be said to be a type of RNA polymerase.

Answer:
D
Explanation:
A water molecule, because of its shape, is a polar molecule. That is, it has one side that is positively charged and one side that is negatively charged. The molecule is made up of two hydrogen atoms and one oxygen atom. The bonds between the atoms are called covalent bonds, because the atoms share electrons.
Are most environmental issues local problems or global problems?
How can or will this affect the way we try to solve these issues?
How are environmental issues becoming more complex?
What about the history of environmental studies can inform us about our current environmental issues? Why is it important to understand the past to help solve current and future environmental problems?
Answer:
Most environmental issues are problems on a global scale, these include but are not limited to, global warming, ozone pollution, greenhouse gases and many more issues.
This affects the way we try to solve these issues because if we dont all play a part to help change the way things are going, then they will only get worse. We have to come together as a whole.
Unlike individual efforts, different countries can cooperate and implement legislation which limitates all the countries in the globe,solving environmental issue more efficiently.

Explanation:
Tectonic plates are pieces of the rocky outer layer of the Earth known as the crust. These plates are constantly moving, and volcanoes and earthquakes are found at plate boundaries.
At the borders of major tectonic plates, earthquake and volcanic activity is evident. The correct option is b.
What are tectonic plates?A tectonic plate (also known as a lithospheric plate) is a huge slab of solid rock that is made up of both continental and oceanic lithosphere. Plate size can range from a few hundred kilometers to hundreds of kilometers; the Pacific and Antarctic Plates are among the largest tectonic Plates.
The majority of volcanoes and earthquakes form at the tectonic plate boundaries of the Earth. These plates are massive slabs of the Earth's crust and upper mantle that fit together like puzzle pieces.
Tectonic plates are fragments of the crust, the Earth's rocky outer layer. Volcanoes and earthquakes can be found along plate boundaries because these plates are continually shifting.
Therefore, the correct option is b. Earthquake and volcanic activity are evident.

Someone please help ill give you brainliest!!!
Answer:
Work is the transfer of energy , Energy is the capacity for doing work , and Power is work being done in a unit of time.
There are 2 types of energy
Kinetic Energy : Energy of Motion
Potential Energy : Stored Energy
When calculating work energy and power you use WORK = W=Fd
Because energy is the capacity to do work , we measure energy and work in the same units. Power's SI unit of measurement is the Watt, representing the generation or absorption of energy at the rate of 1 Joule/sec. Power's unit of measurement in the English system is the horsepower, which is equivalent to 735.7 Watts.
