Describe the structure and function of the cell membrane. I hate science;-;
Answer:The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.
Explanation:
The cell membrane is a dynamic selectively permeable structure.
What is the cell membrane?
A cell is protected by its cell membrane, also known as the plasma membrane. Additionally, it maintains a constant environment inside the cell, and that membrane serves a variety of purposes.
One is to move compounds out of the cell that is harmful as well as nutrients into the cell. Another is that there will be proteins on the cell's membrane, which is its plasma membrane, that interact with other cells.
These proteins may be lipid proteins, which include both a protein and a fatty acid, or they may be glycoproteins, which contain both a protein and a sugar moiety. Additionally, those proteins that adhere outside of the plasma membrane enable cell-to-cell communication.
Additionally, a cell's membrane offers some structural support. Additionally, various cell types have different types of plasma membranes, and the lipid component of the plasma membrane generally contains a lot of cholesterol. This is distinct from a few other membranes inside the cell. There are several plants and microorganisms, such as bacteria and algae, that have various defense systems.
Therefore, the cell membrane is selectively permeable with a variety of functions.

Living organisms are made up of cells. Cells are organized at different levels to form very complex living organisms like your body. Each level has a specific role or job to perform. Which of the following lists these levels in the correct order of organization from the simplest to the most complex? A. Cells, tissues, organs, organ systems, organisms B. Organisms, organ systems, organs, tissues, cells C. Tissues, cells, organs, organisms, organ systems D. Organs, organ systems, organisms, cells, tissues
Answer:
A. Cells, tissues, organs, organ systems, organisms
Cells, tissues, organs, organ systems, organisms is the correct order of levels of organization. The correct option is A.
What is level of organization?Biological organization is the reductionistic hierarchy of complex biological structures and systems that define life. The traditional hierarchy basically goes from atoms to biospheres.
These components are organized into levels. Cells, tissue, organs, organ systems, and organisms are the five levels.
Cells are the building blocks of all living things. This is what sets living things apart from other objects.
The organism level is the most advanced level of organization. An organism is a living being with a cellular structure that can perform all physiologic functions required for life on its own.
An organism is organized into four levels: cells, tissues, organs, and organ systems. These levels group complex anatomical structures; this organization creates the components easier to understand.
Thus, the correct option is A as cell is the basic level while organism is the highest level of organization.

How do you think improving technology to identify locations of fossil fuels could benefit people and the environment?
Answer:
Alternative, renewable energy sources, like wind and solar power, get rid of the pollution that accompanies fossil fuel energy. Alternative energy also reduces the reliance on limited fossil fuels.Explanation:
Improving technology to identify the locations of fossil fuels could benefit people and the environment by saving energy, reducing pollution, and being economically beneficial.
What is the significance of the technology in fossil fuels?Using the technology helps the economy by improving technology, which could lead to the discovery of new fossil fuel reserves, identifying new fossil fuel reserves could help reduce dependence on outside sources of energy, thereby increasing energy security. in this way extraction should be more efficient and less harmful to the environment, such as through the emission of fewer harmful gases during mining.
Hence, improving technology to identify the locations of fossil fuels could benefit people and the environment by saving energy, reducing pollution, and being economically beneficial.

Explanation:
The independent cycles that add to the problem of Global Warming on our planet that can sometimes be measured are called ___________________ ___________________. An example is in the artic how the ice is melting. The melting ice exposes more land and then that land heats up and causes the ice to melt faster than just having the sun hit it.
Earth's long-term warming trend can be seen in this visualization of NASA's global temperature record, which shows how the planet's temperatures are changing over time, compared to a baseline average from 1951 to 1980. The record is shown as a running five-year average.
What do you think the distribution of fossil fuels on Earth suggests about what Earth was like millions of years ago? Support your answer with evidence.
Answer: Years ago, when prehistoric animals and plants died, layers of rock and dirt gradually buried them. Over millions of years, heat and pressure from Earth's crust ... that are useful to humans, like fossil fuels, are called natural resources. ... life and provides real-life examples such as scientist have found fossals in museums
Explanation:
The distribution of fossil fuels on Earth suggests that the population was low when compared to now and there was also less technology adopted.
Plants and animals which died millions of years ago were gradually covered
with dust through wind erosion as a result of less technological innovation
such as burying in coffins etc. They were put in tombs which made fossils to
be discovered as a result of direct contact with rocks and soil components.
The population of plants and animals were also lesser than then which is why fossils are sparingly distributed across the world.
