Answer:
Thrust and Lift.
Method:
There are 4 forces acting upon a plane while it is moving. Drag (The air friction while it's in the air), Lift (Generated by the wings (The upward force), Weight (How heavy the plane is), and finally, Thrust (Generated by the engines which moves the plane/wings through the air generating lift). If there is enough air going over the wing at a high enough speed, and Thrust, and Lift overcome the other two forces keeping the plane on the ground, it can fly. The air pressure under the wing is higher than over the wing - If you have ever ran you hand under the water keeping it flat, you may notice it going up, those are basically the same forces, but under water.
How does the pressure under the wing affect the lift?
The difference of air pressure over the wing (which is less), which also means less force bringing the plane down. The air pressure under the wing is higher, putting pressure on the wing moving it up. A wing is designed to make the air travel a longer distance over the wing than under the wing creating the air pressure. The engines just enforce that process.
A long note about Artificial Pacemaker (I WILL MARK YOU AS BRAINLIST PLS HELP)
Answer:
A cardiac pacemaker is a medical device that generates electrical impulses delivered by electrodes to cause the heart muscle chamber to contract and therefore pump blood by doing so this device replaces and/or regulates the function of the electrical conduction system of the heart. The primary purpose of the pacemaker is to maintain an adequate heart rate, either because the heart’s natural pacemaker is not fast enough or because there is a block in the heart’s electrical conduction system.

energy capture
A. where light energy is not available.
B. in oxygen-rich environments.
C. when water has a pH of 7.
Answer: the answer would be a
Explanation: because I had the same question too on acellus and got a right
Photosynthesis makes use of light energy while chemosynthesis is the main source of energy capture where light energy is not available.
What is photosynthesis?It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy through the process of cellular respiration.
Some of the energy which is converted is stored in molecules of carbohydrates like sugar and starches which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.
The process begins with proteins absorbing light energy which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.

Why is it important for scientists to state a conclusion?
Answer:
it summarize how your results support or contradict your original hypothesis:
Hydrolysis of a protein will lead to the formation of monosaccharides.
True
False
Answer:
True
Explanation:
Because it would do that.
Hydrolysis of a protein will NOT lead to the formation of monosaccharides.
Hydrolysis of protein leads to amino acids not monosaccharides because amino acid is the building block of proteins means protein is made up of amino acids while on the other hand, the hydrolysis of carbohydrates such as polysaccharide and disaccharide etc leads to monosaccharide. Various monosaccharide combine together forming polysaccharide and disaccharide so we can conclude that the statement is false.

a problem that confounds attempts to organize the entire living world for study?
Answer:
A problem that confounds attempts to organize the entire living world for study is the need of evolutionists to bring the entire diversity of living things ultimately into.
In biology, living things can all be classified in accordance with other living things that share a specified set of common characteristics. A major challenge to the process of classification is that, in evolution, that this involves the need to classify all living things. The challenges being that there are many species on planet earth that once existed and are now extinct (i.e. they cannot currently be studied in living form) and that there may be species that do exist that have yet to be discovered and therefore cannot be classified. Finally, due to the sheer number of species on earth, it will literally take hundreds of years for scientists to classify all species.

Answer:
It cannot be mixed with any other type of insulin
Explanation:
Glargine insulin is a long-acting basal insulin. This i the Option marked C
What is insulin?
A kind of insulin used to control diabetes is glargine insulin. It falls within the category of long-acting basal insulin. In order to meet the body's regular insulin requirements between meals and during fasting periods, basal insulins offer a gradual and consistent release of insulin over a lengthy period of time.
Glargine insulin maintains blood sugar control for a considerable period of time, usually up to 24 hours, with a generally steady and protracted action.
