Answer:

Carbon cycle.

Explanation:

Biogeochemical cycle are the cycles present in the atmosphere that regulates the composition and amount of the elements in the atmosphere. Two main types of cycle are sedimentary cycle and gaseous cycle.

The carbon cycle consists of the reservoir of carbon in the form of carbonates and the fossil fuels. These components are exchanged in the atmosphere with the help of carbon cycle. The carbon cycles regulates and maintains the component of carbon in nature.

Thus, the answer is carbon cycle.

lara31 [8.8K]

Answer:

The correct option is option D which is  10 – 1 molecule of Oxaloacetate (OAA) is regenerated for every molecule of Acetyl-Coenzyme (AcCoA) used.

Explanation:

As the complete question is not given, the complete question is as below

Imagine that I start off with 10 molecules of oxaloacetate in a mitochondria. After running the TCA to generate 20 molecules of CO2, how many molecules of oxaloacetate will be left in the mitochondria (assuming oxaloacetate is being used only for TCA in these mitochondria)?

A) 30 – each molecule of CO2 generated corresponds to an increase of one OAA

B) 20 – every two molecules of CO2 generated corresponds to an increase of one OAA

C) 0 – two molecules of CO2 generated corresponds to one AcCoA used in the TCA; each AcCoA requires one molecule of OAA

D) 10 – one molecule of OAA is regenerated for every molecule of AcCoA used

Each cycle of TCA result in consumption of 1 Acetyl-Coenzyme (AcCoA) and 1 Oxaloacetate (OAA) molecule to give rise to 3 molecules of NADH and 2 molecules of CO2 per cycle. But at the end of each cycle, OAA molecule is regenerated. So the number of oxaloacetate(OAA) molecules remains unchanged.

Thus the correct option is option D which is  10 – 1 molecule of Oxaloacetate (OAA) is regenerated for every molecule of Acetyl-Coenzyme (AcCoA) used.

What is the name for the science that studies evolution that oc-
abruzzese [7]

Answer:

D. Population genetics

Population genetics is the study of genetic variation within populations, and involves the examination and modelling of changes in the frequencies of genes and alleles in populations over space and time. ... In natural populations, however, the genetic composition of a population's gene pool may change over time.

Explanation:

microevolution - evolutionary change within a species or small group of organisms, especially over a short period. (Not studying the overall evolution in the population, just a single allele usually) Not it then

macroevolution - Macroevolution in the modern sense is evolution that is guided by selection among interspecific variation, as opposed to selection among intraspecific variation in microevolution (this goes over huge groups of different species) Not it then

gene pool - The gene pool is the set of all genes, or genetic information, in any population, usually of a particular species. (Not the study of evolution in a population) Not that then

So it has to be D

Can a human make amino acids or does he or she have to always get amino acids from eating food?
meriva
Humans get amino acids from protiens in the food we eat. As we digest the food, the enzymes in our stomach and small intestines break down proteins into small amino acids. So technically, we do not make amino acids, we get amino acids from eating food high in protiens.
