64 cells have been produced from one frog egg cell after 3 hours.
Do human eggs just contain one cell?Nevertheless, the egg is a single cell when it is placed down by the female; after being fertilized by the single cell or nucleus of the male sperm, the egg still exists as a single cell but now possesses a complete set of chromosomes and DNA.
The frog cell divides once every 30 minutes. The following amount of divisions takes place in 3 hours:
30 minutes =one division.
3 *60-seconds =1/30*180.
=6 divisions,
After n divisions, the number of cells that result can be calculated using = 2^n

What happens to undigested unabsorbed food in left in small intestine?.
The undigested food stuff enters the colon, where the majority of the water is reabsorbed, after passing through the small intestine.
The stomach and small intestine are where the majority of food is digested, but the large intestine receives the leftover food that hasn't been fully broken down. The water in the large intestine is absorbed, and the food that is still undigested is kept in its lower portion, or rectum. It subsequently transforms its undigested food into the semi-solid substance that is kept in the rectum.
The food is subsequently moved from the rectum to the urine bladder, the urethra, and ultimately the anus region, where it is then expelled from the body.

Which two substances does the Calvin cycle produce?
a. H2O
b. ADP
c. CO2
d. a 3-carbon sugar
Answer:
b) ADP
d) a 3-carbon sugar
Explanation:
The Calvin cycle is one of the biological processes that happen in the chloroplast stroma during photosynthesis. Its main job is to turn CO2 into glucose, a sugar with three carbons.
The Calvin cycle makes the production of two substances:
a 3-carbon sugar: At the beginning of the Calvin cycle, carbon dioxide molecules are fixed and changed into 3-phosphoglycerate. This 3-carbon molecule is changed into glyceraldehyde-3-phosphate (G3P) by enzymes. Some G3P molecules make the original donor molecule full again, while others make glucose and other carbs.Adenosine diphosphate (ADP) is a key part of how cells use energy. ATP powers the steps in the Calvin cycle. Through cellular metabolism, ATP is used up and turned back into ADP. ADP can be replaced and turned back into ATP.Find out more about what photosynthesis produces.

What is a problem that a cell needs to overcome if its volume is very large relative to its surface area?.
A cell will divide or die if there is inadequate surface area to maintain its rising volume.
Cells must continually interact with their surroundings in order to live. Gases and food molecules that the cell requires are dissolved in water and must be absorbed, as are waste products of cellular metabolism. All materials enter and exit the cell via the plasma membrane. The interior volume of a cell rises as the cell membrane expands. Because volume rises faster than membrane surface area, the relative quantity of surface area accessible to transmit materials to the a unit volume of a cell continuously declines.
As a result, if the cell develops beyond a certain point, not enough material would be capable of crossing the membrane quickly enough to meet the increased metabolism that occurs as the cellular volume rises. As a result, the cell must either split into smaller cells with favorable surface area/volume ratios or stop functioning.

How does crossing over in meiosis lead to genetic diversity and ultimately higher survival rates in population?.
The biological process of crossing over occurs during prophase I of meiosis when genetic material is transferred across non-sister chromatids of homologous chromosomes. By giving offspring distinct chromosomes from their parents, chromosomal crossing enhances genetic variety. It is a significant factor causing genetic variation among progeny, which would otherwise cause a large degree of defects or illnesses.
Meiosis specifically produces novel genetic material combinations in each of the four daughter cells. These novel pairings are the result of DNA switching between linked chromosomes. Because of this interaction, the gametes created during meiosis display a remarkable diversity of genetic variation. When genes cross over or recombine during meiosis, the alleles on each chromosome of a homologous pair are rearranged, enabling the mixing of father and maternal genes, either of which can be expressed in the progeny.

what would happen if a cell went through mitosis without finishing s phase?
DNA replication in the S phase is necessary for mitotic cell division.
As the parent cell evenly divides its nuclear material across the two daughter cells, this stage is crucial for cell division. Every generation, the number of chromosomes will fall by half if there is no S phase. DNA synthesis or replication takes place during the S phase of the a cell cycle, which happens during interphase and comes before mitosis or meiosis. By doing this, a cell's genetic material doubles before it begins mitosis or meiosis, providing enough DNA for the cell to divide into daughter cells. The goal of the very dynamic process of mitosis is to divide identical copies of the genome into two daughter cells. Cells are produced when the mitotic process fails.

myelin increases the speed of conduction because it
Myelin increases the speed of conduction because it acts as an insulator.
Myelin is a fatty substance that surrounds the axon of certain nerve cells, it is composed mainly of lipids. It acts as a barrier between the axon and the surrounding tissue, which helps to increase the speed of action potential conduction along the axon.
Myelin helps to speed up conduction in two main ways:
Saltatory conduction: Myelin allows for saltatory conduction, which means that the action potential "jumps" from one node of Ranvier (an unmyelinated region of the axon) to the next, rather than traveling the entire length of the axon.
This is a more efficient method of conduction and allows for faster transmission of signals.
Reduced membrane capacitance: The myelin sheath reduces the capacitance of the membrane and thus reduces the amount of current required to initiate an action potential.
Overall, the presence of myelin allows for faster and more efficient conduction of nerve impulses, which is important for proper nervous system function.
