Answer:
An atom is the smallest unit of a pure substance or element that can exist and still retain the properties of the original substance or element. Common substances, such as air, water, wood and cloth are mixtures of materials and can be chemically or physically broken down into simpler substances.
Answer:
elements cannot be broken down into a simpler substance.

What is the molecule that is formed as a result of the acceptance of hydrogen ion and the final acceptor molecule.
Answer:
Water (H2O)
Explanation:
The final acceptor molecule in the electron transport chain is oxygen. When oxygen accepts hydrogen ions, it forms water. This is why water is released as a byproduct of cellular (aerobic) respiration

eukaryotic cells differ from prokaryotic cells in that eukaryotic cells
Answer:
Eukaryotes are organisms whose cells have a nucleus enclosed within a nuclear envelope. Eukaryotes belong to the domain Eukaryota or Eukarya; their name comes from the Greek εὖ and κάρυον. The domain Eukaryota makes up one of the domains of life in the three-domain system; the two other domains are Bacteria and Archaea. Eukaryotes represent a tiny minority of the number of living organisms; however, due to their generally much larger size, their collective worldwide biomass is estimated to be about equal to that of prokaryotes. Eukaryotes evolved approximately 1.6–2.1 billion years ago, during the Proterozoic eon.
Explanation:
Answer:
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. ... The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles.

What are some causes and effects of disease?
Answer:
Explanation:
CAUSE
Bacteria. These one-cell organisms are responsible for illnesses such as strep throat, urinary tract infections and tuberculosis.
Viruses. Even smaller than bacteria, viruses cause a multitude of diseases ranging from the common cold to AIDS.
EFFECT
Diseases can affect people not only physically, but also mentally, as contracting and living with a disease can alter the affected person's perspective on life. Death due to disease is called death by natural causes.
Why is the relationship between surface area and volume central to many cellular processes?
Answer:
The greater the surface-area to volume ratio of a cell, the easier it is for the cell to get rid of wastes and take in essential materials such as oxygen and nutrients.

Leukemia is cancer of the body’s blood-forming tissues. A leukemia patient’s bone marrow produces abnormal white blood cells which do not function properly. A pharmacology company is trying to develop drugs to regulate the production of abnormal white blood cells. Which of the following processes is most likely affected by this new drug?
Cellular respiration
Transport of molecules
Cell differentiation
Cellular division
Answer:
Cellular division
Explanation:
it's because abnormal production (mutations) causes leukemia
cellular division is most likely affected by this new drug in case of leukemia. Thus option D is correct.
What is leukemia?Leukemia is a cancer related abnormal division in blood or blood-forming cells. It is other wise known as blood cancer.
The exact cause is not known, major risk factors are radiation exposure, chemotherapy for cancer, smoking, family history of leukemia, and exposure benzene.
Leukemia cells, do not clump to form tumor, due to this leukemia is not diagnosed through imaging tests.
Common symptoms include pain in the bones, swollen lymph,, bleeding and bruising nodes, feeling weak, fevers or night sweats etc.
Leukemias can be acute or chronic.
On the basis of cell type affected four types of leukemia observed such as acute lymphoblastic leukemia (ALL), chronic lymphocytic leukemia (CLL), acute myelocytic leukemia (AML), and chronic myelocytic leukemia (CML).
Thus option D is correct.

The diffusion of water molecules in and out of cells is very common.
Which of the following is the process by which water moves across a
membrane, from an area of high concentration to low concentration,
without the use of energy? *
osmosis
hydrolysis
photosynthesis
cyclosis
Osmosis is the process; it is essentially diffusion, which is a spontaneous (no energy input required) process as applied to water.
----------------------------
Hydrolysis is incorrect; that describes a type of chemical reaction in which water breaks a chemical bond.
Photosynthesis is incorrect; that describes the complex process in which energy in light is converted into chemical energy.
Cyclosis is incorrect; that describes the movement of cytoplasm within a cell. There is no spontaneous, net movement of water across a concentration gradient.

Answer:
Hey mate,here is your answer. Hope it helps you
Explanation:
Local winds are basically of two types:-
Land BreezeSea BreezeThe sea breeze is a thermally produced wind blowing during the day from the cool ocean onto the adjoining warm land. It is caused by the difference in the rates of heating between the land and the ocean. The bigger the difference in temperature, the stronger the wind.
For example, hot land temperatures next to cold ocean temperatures will create a stronger sea breeze than land temperatures that are only a little bit warmer than the ocean temperatures. So during the afternoon when the temperatures differences are normally at their highest, the sea breeze will normally be at its strongest, bringing relief from the heat to beachgoers.
This process also works in reverse at night. Only this time it is known as the land breeze. The land breeze is a coastal breeze at night blowing from the land to the ocean. It is caused by the difference in the rates of cooling of the land and of the ocean. Once again, the bigger the difference in temperature between the two, the stronger the wind.
Answer: The explorer should enter the harbor at daytime, because it is very bright and he can see where he goes. The explorer should go home when it is dark. Hope this helps!

Describe an example of acceleration and explain how velocity is changing
The velocity is changing because the acceleration is present which is non-zero.
What is acceleration?The rate of change of velocity of an object in a particular direction is known as acceleration. The acceleration is a vector quantity and its SI unit is a meter per second square. The acceleration is given as,
a = dv / dt
Where dv / dt is known as change.
According to Newton's Second Law, the amount of an element's acceleration is the joint result of two reasons:
The strength of the net resultant force, which is directly proportional to the sum of all external forces exerted on that item;Depending on the components used to create it, an object's mass is inversely related to its magnitude.The velocity is changing because the acceleration is present which is non-zero.
