Genetic transmission is the mechanism that drive evolution.Asexually reproducing organisms reproducing organisms reproduce using mitosis, while the sexually reproducing organisms reproduce using meiosis.
Both these mechanisms are involved in duplication of DNA which then get passed to offspring and RNA is key component in the duplication of DNA. The genetic information heritable biological information coded in the nucleotide sequence of DNA or RNA.
Genetic material is includes genes and DNA which control the development , maintenance and reproduction of organisms. These messages is passed from generation to generation through inherited units of chemical information. It consist of only two transcription and translation they known as gene expression , during this process of transcription store in gene DNA is passed to similar molecule called RNA in nucleus.

The constancy of the chromosome number from one cell generation to the next is maintained through.
Through mitosis, the number of chromosomes is kept constant from one cell generation to the next.
What occurs during mitosis?A cell divides into two identical daughter cells after duplicating all of its components, including its chromosomes. Due to the importance of this procedure, specific genes carefully regulate each phase of mitosis. Health issues like cancer may develop when mitosis is improperly controlled.
How many phases of mitosis are there?Prophase, pro metaphase, metaphase, anaphase, and telophase are these stages.
What function does mitosis serve?Mitosis' purpose is to divide the genome so that the two daughter cells inherit an identical and equal number of chromosomes.
Where in the cell cycle does mitosis occur?The mitotic phase, which consists of mitosis and cytokinesis and produces two daughter cells, begins after interphase. Despite the fact that the two processes frequently overlap, mitosis occurs before cytokinesis.

All cells have a nucleus that acts as a command center for the cell.
Answer:
True
Explanation:
it's called the nucleus because that is where the instructions reside for the proteins necessary for cellular functions and for the building blocks of the cellular components
The statement is true for all eukaryotic cells because prokaryotes lack a well-organized nucleus.
The nucleus is called the command center for the cells because it contains the DNA or genes.
The DNA stores the genetic information, which is necessary for building up the cells and their components.
The DNA can be considered a blueprint for the cell. The genes are organized in long linear DNA molecule which is stored inside the nucleus.
The DNA is stored compactly with the help of histone proteins, which helps store the two meters of DNA in a single cell.

In humans, the dilator muscles of the iris contains fibers that extend radially through the iris of the eye and involuntarily contract as available light decreases, thus dilating the pupil.
Pupillary dilation is controlled primarily by the sympathetic nervous system and interruption of the innervation of the dilator muscle can cause an abnormally small pupil, a condition seen as part of Horner syndrome.
Pupillary dilator increases the size of the pupil to allow more light to enter the eyes. It works in opposition to the pupillary constrictor. The pupil dilation occurs when there is an insufficient light for the normal functioning of eyes or during heightened sympathetic activity, for example during fear .

When is cell-to-cell communication particularly important in regulating gene expression?
Answer:
during embryonic development
Explanation:
Cell-to-cell communication is particularly important in regulating gene expression during the embryonic development.
Cells in the developing embryo are constantly communicating with their neighbors. The molecules used by them in sending and receiving signals are crucial for normal embryogenesis. Various intracellular signaling pathways have been discovered, some of which are activated in response to secreted growth factors.
However, a few important signaling pathways are used often during embryonic development to regulate various cellular processes that shape the developing embryo.
Embryonic development is marked by the thorough regulation of cellular functioning so that the cells proliferate, migrate, differentiate, and form tissues at the correct place and time. These processes are genetically controlled and depend both on the history of cells, their lineage, as well as on the activities of signaling pathways, which coordinate the cell interactions leading to organogenesis.

Ketone bodies are produced from the incomplete breakdown of _____ when _____ is unavailable for the brain and nerve cells.
Ketone bodies are produced from the incomplete breakdown of fats when glucose is unavailable for the brain and nerve cells.
Ketone bodies are the substances which are produced by the liver during gluconeogenesis. Gluconeogenesis involves formation of glucose during fasting and starvation. The three ketone bodies produced by the liver include acetoacetate, beta-hydroxybutyrate, and acetone.
These compounds are utilized in healthy individuals to provide energy to the cells of the body when glucose is low or absent in the diet.
During fasting or starvation, the glucose levels in the blood quickly decrease which stimulates the body to enter the post-absorptive state. In this state, the body starts converting fat back into fatty acids, glycogen into glucose, and even starts breaking down amino acids for energy.
