Explanation:
cell membranes contain a central bilayer formed by:
Answer:
Lipids
Explanation:
The cell membranes are primarily made up of two layers. The central bilayer is formed by the lipids in the cell membrane. Lipids surround the cytoplasm of cells to help the cell control substances that go in and out of the cell. This helps to protect the cell from a harmful substance that may potentially enter the cell.

49. Shoot the Plasma Cell Membrane. The cell membrane is the ___________________________ of all cells. It regulates what ____________________and _____________________ the cell to help maintain homeostasis. The cell membrane is _____________________________ which means it allows substances to pass through, but not others.
Answer:
The cell membrane is one of the great multi-taskers of biology. It provides structure for the cell, protects cytosolic contents from the environment, and allows cells to act as specialized units. A membrane is the cell’s interface with the rest of the world - it’s gatekeeper, if you will. This phospholipid bilayer determines what molecules can move into or out of the cell, and so is in large part responsible for maintaining the delicate homeostasis of each cell.
Explanation:
Cell membranes are semipermeable, meaning they have control over what molecules can or cannot pass through. Some molecules can just drift in and out, others require special structures to get in and out of a cell, while some molecules even need an energy boost to get across a cell membrane. Each cell’s membrane contains the right mix of these structures to help that cell keep its internal environment just right.

third answer is this Responsible Science is a comprehensive review of factors that influence the integrity of the research process. Volume I examines reports on the incidence of misconduct in science and reviews institutional and governmental efforts to handle cases of misconduct.
The result of a two-year study by a panel of experts convened by the National Academy of Sciences, this book critically analyzes the impact of today's research environment on the traditional checks and balances that foster integrity in science.
Responsible Science is a provocative examination of the role of educational efforts; research guidelines; and the contributions of individual scientists, mentors, and institutional officials in encouraging responsible research practices.

Explanation:
A developer proposes building a new geothermal power plant in a city located on the
interior of the North American Plate to provide electricity for a new housing development.
Make a claim using evidence that supports or opposes this proposal.
Based solely on scientific evidence, we can make a claim that supports the idea of a geothermal power plant due to its stability, environmental safety, and high potential.
A geothermal power plant involves hot water being pulled from underground reservoirs located near thermal vents. Once the water reaches the surface, the immediate decrease in pressure causes the water to become steam, this steam, in turn, causes a turbine to spin, which generates an electric current through a generator.
This source of energy is environmentally safe considering its waste product produced is water vapor, making it a great option for modern-day energy requirements. This source of energy also has huge future potential and is very stable due to its being a renewable resource.

Based on the productivity data provided to you, as well as data you collected on algal standing crops and number of catfish at Bat Rocks and Cess, construct an explanation based on evidence for how sunlight regulates the productivity of algae, the number of catfish in a pool, and the resulting standing crop of each. (exploring biomass pyramids interactive simulation)
The biomass of producer is higher than the population of catfish.
Sunlight regulates the productivity of algae by allowing the algae to make their own food through the process of photosynthesis. This algae better the quality of water, provide oxygen for the aquatic organism and food for many herbivore aquatic organism.
Algae needs sunlight, carbondioxide and water for the process of photosynthesis. Catfish population in the pool increases as the biomass of algae increases because more food is available for the catfish which allows them to grow and increase their population.
In pyramid or trophic levels, the biomass of algae and other plants are the largest which is present at the bottom whereas as we go in the trophic level, population of organisms increases so we can conclude that biomass of producer is higher than the population of catfish.

3. Hyphobic - Hate water
4. Phospolipid bilayer - the cell membrane
Explanation:
One type of molecule (or a few molecules that are closely related) is all that a channel will accept for transit.
What role of channel protein and membrane component?A channel protein is an illustration of a transport protein; it serves as a pore in the membrane to permit water molecules or small ions to move through quickly.
Water may quickly diffuse through the membrane thanks to aquaporins, which are proteins that function as water channels. Ion channel proteins enable unrestricted ion transport across the membrane.
Channel proteins span the membrane, forming hydrophilic tunnels that let their target molecules diffusely pass through.
For instance, channel proteins enable the passage of bigger molecules like glucose as well as ions like sodium, potassium, and calcium through the membrane.
Therefore, Large or charged molecules can pass across the membrane to channel proteins.
