Answer:
D) How do living things get energy?
G) How are living things related?
F) Where do living things make their home?
Explanation:
Different types of organisms are present on this Earth which interact with both abiotic and biotic factors and influence the nature of the environment. So there is a need to study the living organisms in which the first thing is to arrange the living organism by a process called classification.
The questions that are necessary to classify the organisms include related to the mode of energy or nutrition, the relation between various species at the morphological and molecular level, the habitat. The relationship between the organism is a very important aspect as it makes the classification easily according to their similarities and dissimilarities.
Thus, the selected options are the correct answer.
Answer:
Biological catalyst has to be cut.
Explanation:
- Enzymes are called "Biological catalyst".
- Enzymes are called Biological catalysts because they diminish the activation energy for reactions. As the activation energy is reduced the rate of reaction is increased.
- Many enzymes modify their state when substrates bind and it is known as "Induced fit".
- Enzymes are nothing but Protein(Biological molecules). Most of the biological reactions are catalyzed by Protein.
- Enzymes improve the rate of synthetic reactions without getting altered forever by the reaction.
- For this reason Biological catalyst are needed to be cut and copy segemnte in DNA.
In this list, find the process or environment that is not affected by microorganisms.
a. oxygen cycles
b. global temps
c. human health
e. all have microbial involvement
correct:
all have microbial involvement
Explanation:
oxygen cycle, global temperatures, human health
all of the above mentioned options have microbial involvement
i.e. all of these processes or environment are affected by microorganisms

C) DNA is made of 4 types of nucleotides
Not all organisms have 46 chromosomes (23 homologous pairs). Not all organisms have nuclei (e.g. bacteria do not have nucleus)
Answer:
The correct answer is option A. "a fossilized fish found in a layer of rock estimated to be between 15,000 and 25,000 years old".
Explanation:
It is estimated that the oldest fossils that can be reliably measured using carbon-14 must be organic and have an age of around 50,000 years. Therefore, a fossilized fish found in a layer of rock estimated to be between 15,000 and 25,000 years old will fit perfectly to be dated using carbon-14. Anything older than 50,000 years old must be dated using other radiometric dating approaches.
