Hey there!
The correct answer to your question is: Skeletal System
The Skeletal System has several functions. It supports the body, permits movement, and protects our organs from damage.
Thank you!
The correct answer is B. Meet current and future resource needs.
Explanation:
Sustainability implies an equilibrium between the natural resources available and the resources humanity requires. This equilibrium is reached when the natural resources extracted from nature are enough to satisfy human needs without depleting the resources or causing these are not available in the future. In this context, the goal of sustainable development is to make sure now and in the future resource needs are meet (option B). Moreover, this is possible through actions such as recycling, reducing deforestation, creating environment-friendly technologies, among others that reduce the depletion of resources or preserve the environment.
Explanation:
(3) active transport
The molecules would be moving against their concentration gradient from a region of low concentration to a region of high concentration.
While cells facilitate the transport of molecules via movement across the cell membrane, there many different mechanisms. These include passive diffusion, facilitated diffusion, and passive transport. However some very large molecules require specialized type of active transport, which requires energy in the form of ATP, in order to move substances across the membrane against their concentration gradient.
Active transport is a mediated process that requires an energy input and the use of specialized membrane proteins to move against the concentration gradient. These proteins require energy in the form of adenosine triphosphate or ATP in order to facilitate necessary conformational changes to the large protein molecules to alter the spatial location of the molecule. For instance, with Na+, K+ pumps in cell membranes.

Answer No 1:
Phospholipids are made up of phosphorus head and two fatty acid molecules. These phosphorus head and fatty acid tail is joined together by glycerol. Fatty acid molecules are made up of Carbon, hydrogen and oxyge. Hence,carbon and hydrogen can be said as two other elements present in phospholipids.
Answer No 2:
The building blocks of lipids are glycerol and fatty acids.
Lipids can be described as vital organic molecules which are not soluble in water. They are made up of chains of carbon, hydrogen and oxygen. Someof the examples of lipids are fats and oils. Lipids are the main molecules present in an organisms cell membrane and hence have huge biological importance.
Answer No 3:
Lipids are biologically important molecules as they play very vital roles in the functioning of an organisms body. Two of the functions of lipids are:
- Lipids and phosphorus molecules combine to form phospholipids. The phospholipids are the main molecules out of which the cell membrane is made. Hence, lipids play an essential role in providing the cell membrane its structure.
- Lipids store energy and provide insulation to the body of an organism.
