Answer:
Conditions in the body must be constantly controlled because cells depend on the body's environment to live and function. The maintenance of the conditions by homeostasis is very important because in the wrong body conditions certain processes (osmosis) and proteins (enzymes) will not function properly.

________ is the passing of traits from generation to generation while _________ is the scientific study of traits being passed from generation to generation.
Answer:
Heredity,Genetics
Explanation:
Heredity is the passing of traits from generation to generation while Genetics is the scientific study of traits being passed from generation to generation.
Traits are the defining characteristics that are passed from generation to generation, and genetics is a branch of science to study heredity.
What is genetics?Genetics is the branch of science to study heredity and evolution, how genes originate and what changes occur over time.
Genes are segments of DNA upon chromosome code for protein, in the genetics gene is the major area of study. How a gene can be transferred from parents to a daughter and lead to heredity can be studied.
Heredity depends on the gene responsible for a particular trait and character, during evolution, there would be changes occur at the genetic level which leads to variation among species.
Therefore heredity is to pass traits, and the scientific study of it is genetics.

Answer:
Elements are pure substances with only one type of atom
Explanation:
Elements are pure substances with only one type of atom
Answer:
There are more substances on Earth than are listed on the periodic table of elements because substances are combinations of the elements. Elements are pure substances with only one type of atom. When two or more elements are combined, compounds are formed. This allows more substances to be created on Earth.

If a DNA molecule has 40% Cytosine, what percent of it would be Adenine? Explain your reasoning.
Answer:
60%
Explanation:
Answer:
:)
Explanation:
The total amount inside of all nitrogenous bases equal to 100%, with cytosine equalling 40%, Adenine would equal 10%, and you also have to include Guanine which would be another 40% equalling 90% then you have Thymine which would be the other 10%

how the collapse of the forest ecosystem on easter island affected the human population that lived there?
Answer:
Essentially, the population that lived on Easter Island was trapped and eventually died off.
Explanation:
The people on Easter Island started creating the famous statues that I'm sure everyone knows about today, to help protect them from possible invaders. Once the people started settling in, they were provided with a number of natural resources and supplies, which unfortunately they had taken these resources for granted. Since they had been using all of the island's resources and using the many trees there for their civilization, they had no means of leaving the island once the last trees were gone. They were pretty much trapped on a dead island due to them causing the island to go through deforestation.

Explanation:
Acid rain eutrophication
Acid rain eutrophication is an example of nonpoint source pollution caused by burning of fossil fuels such as coal.
What is meant by eutrophication?Acid rain eutrophication occurs when the environment becomes enriched with nutrients, increasing the amount of plant and algae growth to estuaries and coastal waters.
What is eutrophication and its causes?Eutrophication is characterized by excessive plant and algal growth due to the increased availability of one or more limiting growth factors needed for photosynthesis .

which of the examples are considered anabolism? select all that apply.
Anabolism is for the synthesis of complex molecules essential in the building up of organs and tissues. It is therefore responsible for the increase in body size. Examples of anabolism are bone growth and mineralization, and muscle mass build-up.
Answer:
DNA nucleotide synthesis or polymerisation or condensation reactions;
Catabolism is breaking down of a larger molecule, so 1 large will become 2 or more smaller molecules;
Anabolism is the opposite, 2 or more smaller molecules will join together to form 1 larger molecules

what gas exchange happens in the respiratory system and what is the large blood vessel that carries blood from the heart to the lungs.
Answer:
Explanation:
The pulmonary artery is a big artery that comes from the heart. It splits into two main branches, and brings blood from the heart to the lungs. At the lungs, the blood picks up oxygen and drops off carbon dioxide. The blood then returns to the heart through the pulmonary veins.
5 A prokaryotic cell is 5.0 um in length. A virus particle is 300 nm in length. How many times larger is the prokaryotic cell compared to the virus particle?
A 2
B 17
C 60
D 167
The prokaryotic cell is 17 times larger as compared to the virus particle.
Both values first need to be converted to the same unit.
5.0 um = 5.0 x [tex]10^-^6[/tex] m
300 nm = 3.0 x [tex]10^-^7[/tex] m
Dividing both values:
5.0 x [tex]10^-^6[/tex] m/3.0 x [tex]10^-^7[/tex] m
= 16.667
Hence, the prokaryotic cell is approximately 17 times bigger than the virus particle.
