Through the mitotic process, two identical diploid daughter cells are produced. Mitosis is preceeded by the interphase and followed by cytokinesis. 7) b. / 8) a. / 9) b. / 10) b. / 11) c. / 12) a.
-------------------------------------------------
The interphase occurs before cell division. It is composed of the G1, S, and G2 stages.
During the G1 stage, the cell duplicates in size. The organelles and other cytoplasmatic structures duplicate. The high intense biochemical activity is characteristic of this stage. During the S stage occurs the DNI molecule replication process. At this point, also happens the synthesis of histones and other associated proteins. The G2 stage is the final one before the cellular division. Here begins the slow process of DNI condensation. Duplication of centrioles completes. Structures such as spindle fibers are assembled.
Mitosis is a process by which, from a diploid somatic cell (2n), two daughter diploid cells (2n) are produced.
Daughter cells are identical to the original cell.
Mitosis occurs in only one phase, divided into four stages.
In the prophase, it occurs chromosomes condensation and nuclear membrane breaks. During the metaphase, chromosomes are taken toward the center of the cell by the spindle apparatus. Once in the equatorial plane, chromosomes line up.Each chromatid joins with a microtubule of opposites poles.
In Anaphase, bonds between chromatids break. They separate and migrate to the opposite poles. In telophase, duplicated chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole.Finally, cytokinesis occurs.
*************************************
Now, according to this theoretical framework, we can answer the questions.
7) b. are identical to the chromosomes of the parent cell.
8) a. The information is duplicated.
9) b. Mitosis is a phase in asexual reproduction that results in the formation of identical nuclei in the daughter cells.
10) b. I and III only
11) c. The cell's DNA is replicated.
12) a. Certain genes are turned on and others are turned off; this action produces adult cells that are specialized

Why do the alveoli fill with fluid.
Answer:
Your lungs contain many small, elastic air sacs called alveoli. With each breath, these air sacs take in oxygen and release carbon dioxide. Normally, this exchange of gases occurs without problems. But sometimes, the alveoli fill with fluid instead of air, preventing oxygen from being absorbed into your bloodstream.
Explanation:
Answer:
The fluid represents the outermost layer of the alveolar surface that is directly exposed to air and thus to the environment. Alveolar fluid prevents desiccation of the epithelial cells and also functions as a physical protection barrier against inhaled particles and irritants. Explanation: hope this helps

what is gene expression
Answer:
Gene expression is the process the cell uses to produce the molecule it needs by reading the genetic code written in the DNA.
Explanation:
To do this, the cell interprets the genetic code, and for each group of three letters it adds one of the 20 different amino acids that are the basic units needed to build proteins.

a single gene only
multiple genes and environmental factors
IQ is determined by ; ( D ) multiple genes and environmental factors
IQ ( intelligence quotient ) is influenced by more than a single gene ( i.e. multiple genes ) and this makes IQ a polygenic trait found in organisms such as humans.
IQ is not only determined by multiple traits but is strongly influenced by environmental factors just like the multiple genes. IQ measures the intellectual ability of humans ( i.e ability to read and think critically outside the box and also think logically . )
Hence we can conclude that IQ is determined by multiple genes and environmental factors

Should farm animals we eat be genetically modified?
Answer:
GE animals may be disease resistant, parasite resistant, and withstand stress. The beneficial trait can likely improve their well being because they will be more productive.
Explanation:
what do both the rho-dependent and rho-independent mechanisms of termination have in common?
How do animals cause erosion.
Answer:
Some animals weather rocks by scraping them as they feed. Other animals change Earth's surface by burrowing into it and moving material. Too many animals in one place can destroy most of the plants, leading to faster erosion.
If too many animals graze the same land area, the animals’ hooves pull plants out by their roots. A land is overgrazed if too many animals are living there. Grazing animals can cause erosion if they are allowed to overgraze and remove too much or all of the vegetation in a pasture.

The pollutants and their respective sources include the following
Carbon dioxide - This is released when burning coal or gas. The burning of
fossil fuels such as coal or gas releases the greenhouse called
carbondioxide and is responsible for increase in infrared absorption to the
earth.
Nitrogen oxide: This is made when nitrogen reacts with oxygen under the
appropriate conditions.
Sulfur oxides : This is contained in emissions from oil refineries. This is
because crude oil which is the major raw material in refineries have large
amounts of sulphur in them which reacts with oxygen to form sulfur oxides.
Volatile organic compounds: These are contained in cleaning, disinfecting,
