If the seawater carbonate ion concentration is 250 µmol/kg, a) what is the approximate rate of calcification, and b) approximately how many days would it take 1 square meter of reef to accumulate 30 mmol of calcium carbonate?
a) The approximate rate of calcification = 10 mmol CaCO₃ per m² per day
b) The approximate number of days for 1 m² of reef to accumulate 30 mmol = 0.3 days
a) Determine approximate rate of calcification
making use of the calcification rate map attached when the seawater carbonate ion concentration = 250 µmol/kg the rate of calcification = 10mmol CaCO₃ per day
b) determine number of days
using the relation below
Amount accumulated = Area * rate of calcification * time taken
where amount = 30 mmol
rate = 10 mmol
Area = 1 m²
time = ?
∴ Time = amount / ( Area * rate )
= 30 / ( 10 * 10 )
= 0.3 days

The endosymbiotic theory hypothesizes that mitochondria formed from prokaryotic cells. What evidence supports the hypothesis?
They are autotrophic and have parasitic relationships.
They have linear DNA similar to bacteria.
They have chromosomes and ribosomes that are similar to prokaryotes.
They have flagella similar to prokaryotes.
The evidence that supports the endosymbiotic theory is mitochondria have chromosomes and ribosomes that are similar to prokaryotes.
Some lines of evidence that supports the endosymbiotic theory include:
Mitochondria are organelles that have their own DNA known as mitochondrial DNA (mtDNA).Mitochondria have their own ribosomes which are capable of synthesizing their own proteins.Mitochondrial ribosomes are more closely (evolutionary) related to bacterial ribosomes rather than eucaryotic ribosomes.Mitochondria also have their own cell membranes.In conclusion, the evidence that supports the endosymbiotic theory is mitochondria have chromosomes and ribosomes that are similar to prokaryotes.

The student's score in the concentration test is the dependent variable. Option B is correct.
What is the dependent variable?
It is the variable that is dependent upon the other factors in the experiment. It is usually the final result of the experiment.
The student's score on the concentration test depends upon the student's ability to concentrate, stay awake, and heart rate.
Students' ability to concentrate, stay awake, and heart rate is independent variables.

Describe a phase of mitosis?
Mitosis is the division of a parent cell into two daughter cells which contain the genetic material which is exactly similar to parents. The daughter cells are often called as clones.
What is Mitosis?
Mitosis is also known as Equational division. Mitosis is the process of cell division, in which the nucleus undergoes division in eukaryotic cells that occurs when a parent cell undergoes division to produce two identical daughter cells.
During the process of cell division, the karyokinesis is followed by the cytokinesis. Karyokinesis is the division of nucleus and it is divided into four phases: Prophase, Metaphase, Anaphase, and Telophase. In the prophase of mitosis, the spindle fibers starts attaching to the chromatids of chromosomes and the chromatids becomes distinct which are then arranged on the equatorial plane and later divides into two daughter cells.

What kinds of things do the functional domains of proteins interact with
(at molecular level)?
Protein domains are evolutionarily conserved regions of the proteins that play different biological functions. These regions can interact with DNA, RNA, and proteins (protein-protein interactions).
In DNA binding proteins, protein domains interact with DNA in order to regulate transcription, replication, recombination, etc.DNA binding proteins such as transcription factors interact through amino acids localized in specific domains with the atoms exposed in the major groove of DNA. These atoms vary depending on the nucleotide that interacts with the transcription factor.Some of the most common motifs observed in protein domains that interact with DNA include, among others, the basic helix-loop-helix motif, leucine zipper motif, zink finger motif, etc.RNA-binding proteins (RBPs) are proteins having specific domains that interact with RNA to form ribonucleoproteins.In protein interactions, protein domains interact with each other.Learn more in:
