Answer:
Explanation:The phospholipid bilayer formed by these interactions makes a good barrier between the interior and exterior of the cell, because water and other polar or charged substances cannot easily cross the hydrophobic core of the membrane. Can water cross the plasma membrane at all?
It also helps the cell move things in and out. The cell membrane is made of what is called a phospholipid bilayer, which means it has two layers of phospholipids. ... This allows the phosphates to be exposed to water, either in the cell or the environment, while the lipids are protected from water Lipids are essential for all life on Earth. They play many important roles in maintaining the health of an organism. Arguably the most important function lipids perform is as the building blocks of cellular membranes. Other functions include energy storage, insulation, cellular communication and protection.Large quantities of water molecules constantly move across cell membranes by simple diffusion, often facilitated by movement through membrane proteins, including aquaporins. In general, net movement of water into or out of cells is negligible.
this would be Prokaryotes because bacteria are single celled organisms
Answer:
three organisms battling over limited resources
Explanation:
It is limitted resources so there will be competition between the animals
It could be this one -
three organisms of the same species living in an area
BUT...
The other one says limitted resources.
Answer:
After 14 years the population of these birds reached to 300.
Explanation:
The main reason for the extinction or decrease in population of these birds are over hunting or the introduction of invasive species in the ecosystem. Due to over hunting by humans many beneficial species are extinct which causes imbalance in the ecosystem which can't be corrected. These population should be increased by providing a suitable environment to these birds.
Genetic Engineering is the main technology used by humans to influence traits in plants and animals. Humans have used technology to manipulate genes through genetic modification, genetic therapy, selective breeding, and animal husbandry. Genetically Modified Organisms(GMOs) are the result of humans utilizing technology for gene manipulation.
