Answer: Simple Diffusion Across the Cell (Plasma) Membrane: The structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down their concentration gradient, by simple diffusion.
Explanation: Large molecules like glucose or carbohydrates use proteins to help move across cell membranes. Some of the membrane proteins have carbohydrate Chains attached to help cells in recognize each other and certain molecules

Some viruses attack cells by inserting their own DNA into the host cells’ DNA. Why might it be simpler for these viruses to attack prokaryotic cells than eukaryotic cells?
A. Prokaryotic cells have less DNA than do eukaryotic cells.
B. The rapid growth of prokaryotic cells generates more viruses.
C. Unlike eukaryotic cells, prokaryotic cells do not have a nucleus.
D. The cell wall in prokaryotic cells is a less effective barrier.
Answer:
C
Explanation:
Because eukaryotes have membrane bound nucleus where they store their generic information
Scientists discovered that the inner core of Earth is a solid. Explain what evidence supports this thinking. Be sure to include how pressure, temperature, and density play a role. (4 points)
Answer:
The inner core is solid because the inner core consists of a lot of pressure and high temperatures. And the more pressure and high temperatures the more dense the substance gets.

Explanation:
If more carbon dioxide was made
available to a plant, what would be the
effect on the rate of photosynthesis?
A. The rate would be unaffected.
B. The rate would increase.
C. The rate would decrease.
Answer:
B. The rate would increase.
Explanation:
Increased carbon dioxide concentration increases the rate at which carbon is absorbed into the carbohydrate in an independent reaction, so the level of photosynthesis usually increases.

All proteins found embedded in the cell membrane are transport proteins
Answer:
False!
Explanation:
False: All proteins embedded in the cell membrane are not transport proteins instead they are not just involved in transportation of molecules but also in other functions.
Cell membrane is the outer covering of most of the type of cells except in plants and bacteria where cell wall is the outermost layer.Cell membrane is made up of phospholipid bilayer. The proteins embedded in the cell membrane are not only the transport proteins but proteins that are responsible for cell to cell communication, responsible for maintaining shape of the cell, and those responsible for triggering chemical messengers all are present.Learn more about cell membrane:

When discussing Newton’s laws of motion, which terms do people most likely use when talking about Newton’s third law of motion?
A. “action” and “reaction”
B. “mass” and “inertia”
C. “inertia” and “force”
D. “force” and “acceleration”
Answer:
A. action and reaction
Explanation:
the third law is:-
Every Action has it's opposite and equal Reaction
Answer:
The correct answer is "action" and "reaction".
Explanation:
Newton's Third Law is: "for every action, there is an equal and opposite reaction". This means that every time something is pushed on, the other object pushes back. For example, when a swimmer pushes off the wall of a pool, the wall will push back on the swimmer, giving them the push they need to swim to the other side.
After cell division (mitosis) how does the genetic code of the newly
produced cells compare to the code of the parent cell?
Answer:
Chromosomes were first named by cytologists viewing dividing cells through a microscope. The modern definition of a chromosome now includes the function of heredity and the chemical composition. A chromosome is a DNA molecule that carries all or part of the hereditary information of an organism. In eukaryotic cells, the DNA is packaged with proteins in the nucleus, and varies in structure and appearance at different parts of the cell cycle.
Explanation:
Cells reproduce genetically identical copies of themselves by cycles of cell growth and division. The cell cycle diagram on the left shows that a cell division cycle consists of 4 stages:
G1 is the period after cell division, and before the start of DNA replication. Cells grow and monitor their environment to determine whether they should initiate another round of cell division.
S is the period of DNA synthesis, where cells replicate their chromosomes.
G2 is the period between the end of DNA replication and the start of cell division. Cells check to make sure DNA replication has successfully completed, and make any necessary repairs.
M is the actual period of cell division, consisting of prophase, metaphase, anaphase, telophase, and cytokinesis.
about artificial selection, determine if YOU think the benefits of artificial selection outweigh the disadvantages.
PLEASE HELP!!!!
Answer:
What YOU think
Explanation:
That's what it asks, but here are some points to help you along your way: Artificial selection has brought about the extinction or overpopulation of certain species. This can be seen in the avocado or banana industry. Consumers like the smaller, sweeter species of avocadoes. This caused that species to explode and the old ones to become endangered as farmers grew only that type and bred them selectively. Consumers like the smaller, less mushy, less sweet banana species, so now an amazing species of banana is extinct because the forests that used to have them now no longer exist or were changed to grow only that type of banana. Flip it to the animal side, and it's the same story. Those turkeys that the president "Saves" every year? because of artificial selection, that turkey dies a few weeks later because he grew too plump. Why? Because those turkeys are artificially selected to grow much larger than a normal turkey, and their lifespan is not in mind as they are grown for meat. Also, I hope all of this work gives me brainliest :/

We have learned Kepler's Laws, Newtons laws of Motion and Gravity, as well as where planets are in relationship to the sun. Knowing these things can you provide two generalized statements about the planets and yourself or about the planets and the laws.
Answer:
''Planets moves around the sun with constantly changing speed.''
''The sun uses its gravity to pull the planets towards it''
Explanation:
These two statements describes Newtons laws of Motion and Gravity. With statement 1, which shows the motion of the planets constantly changing due to the attraction of the sun. When the planets come close together to the sun, its orbital speed increases while on the other hand, when the planets goes farther from the sun, its orbital speed decreases. The statement 2 indicates that sun attracts other planets due to its gravity which allow them to move in a curved.
Cellular respiration is a process in which animal cells use ____ taken in from the atmosphere.
1) carbon dioxide
2) hydrogen
3) oxygen
Answer:
How does cellular respiration work in animals?
When an animal breathes, it takes in oxygen gas and releases carbon dioxide gas into the atmosphere. This carbon dioxide is a waste product produced by the animal's cells during cellular respiration. Cellular respiration occurs in the individual cells. Digested foods have chemical energy stored in them.
