Distinguish between catabolism and anabolism, giving an example of each reaction as endergonic or exergonic:
Answer: Anabolism builds complex molecules from simpler ones, while catabolism breaks large molecules into smaller ones.
Explanation:
a-Glycerol reacts with fatty acids to make lipids:
CH2OHCH(OH)CH2OH + C17H35COOH → CH2OHCH(OH)CH2OOCC17H35
Simple sugars combine to form disaccharides and water:
C6H12O6 + C6H12O6 → C12H22O11 + H2O
c-During cellular respiration, glucose and oxygen react to yield carbon dioxide and water
C6H12O6 + 6O2 → 6CO2 + 6H2O
In cells, hydroxide peroxide decomposes into water and oxygen:
2H2O2 → 2H2O + O2
Of all other elements on the periodic table some are critical what name represents those others and what function do they serve for humans?
Answer:
They are called Trace elements
they function as catalysts for enzymatic reactions
in some oxidation-reduction reactions (Cu) for some metabolic reactions to for ATPs synthesis,and
also as oxygen carrying elements in Hb and myoglobin muscles e,g(Fe)
Explanation:
Basically Trace elements are group of minerals in small quantity in living organisms.Their functions may be important or essential to the organisms,or needed in small amounts non essentials.
Example of these elements are Fe,Zn,Se,Cu,I,Mn Mb. etc
They are also involved in prevention of some diseases .Generally when they are consumed in large amounts they are toxic to living cells.
others like aluminum, cadmium, mercury lead may beneficial to living organisms,but there role has not yet be verified.
What type of consumer do you think this coyote is? Can you tell from the photo that the coyote is not an omnivore?
Answer:
Carnivore.
Explanation:
Based on the picture alone, the coyote is eating meat, which would make it a carnivore.
Cayote is a tertiary consumer.
The photo alone cannot tell us cayote is not an omnivore.
Tertiary consumers are organisms on the fourth trophic level of a food chain. Most tertiary consumers like the cayote are omnivores.
Omnivores feed on both plants and animals. The cayote feeds not only on other animals like ducks, squirrels, fish, grasshoppers, but also feed on young plants and berries form plants.
The photo only shows us a cayote feeding on just one source of its diet which is a smaller animal. It cannot tell us that the cayote is not an omnivore because it doesn't show us the entire food web of the cayote in its ecosystem.
In conclusion, the cayote is a tertiary consumer. You cannot tell the cayote is not an omnivore from the photo.

A pesticide manufacturer claims that a new product will decrease the pest population by 25% more than the current pesticide. A population of 75
beeties of the same species us exposed to the new pesticide for a 10-week period. A separate population of the same species of beetle is exposed to
the same amount of the current pesticide for a 10-week period. The data collected is sent to an independent research company to verify the results,
Which statement BEST explains how an independent research company verifies data to ensure unbiased results,
The company sends out the data to another researcher to investigate
The company tests many types of pesticides and draws its own conclusions
The company performs the same investigation and compares the results
The company compares the data given to similar investigations
Answer:the company will perform the same investigation and compare the results to the manufacturers
Explanation:
Just did the quiz
The independent research company performs the same investigation and compares the results.
Scientific experiments must be reproducible. For the results of a scientific experiment to be reliable, other scientists must be able to carry out the same experiment and obtain similar results as reported. This is what it means for results to be reproducible.
Hence, for the independent company to ensure that the results are unbiased, the company performs the same investigation and compares the results.
