how does the structure of simple cuboidal connect to its function
Answer:
Simple cuboidal epithelial tissue is specialized for diffusion and absorption. The reason our kidneys function the way they do is because of the movement of water and salts in and out of the kidney tubules.Likewise, the cuboidal shape of the cells allows greater surface area for absorption to take place.

It is now A G C A A C C C G T C T T G G T C G T T G G G C A G A A C C Use your knowledge of mutation and protein synthesis to answer the following questions. What mutation has occurred
The mutation that has occurred is substitution mutation.
Mutation is defined as the random changes in deoxyribonucleic acid (DNA) that alter genetic information, and so can introduce new characteristics.
Mutation can occur in because of the following reasons stated below:
When exposed to environment saturated with ultraviolet light, it can cause cell mutation; andWhen exposed to certain chemical such as free radicals.A typical example of mutation that occurs in DNA is the substitution mutation.
Protein synthesis is the process used by cells to produce usable specific proteins as directed by the DNA.
The base sequence in DNA determines the sequence of amino acid in peptide.
Substitution mutation occurs when one base is incorrectly replaced in the complementary strand of a DNA.
From the DNA base sequence given,
Cytosine replaced Thymine; andGuanine replaced Adenine.This replacement that occurred will lead to abnormal protein synthesis.

In cellular reproduction, ___ ALWAYS occurs in 5’ to 3’ direction
Answer:
DNA replication
Explanation:
DNA replication is the process whereby the genetic material (DNA) duplicates itself into two identical copies. This process must occur prior to any cellular division (meiosis or mitosis) in order to ascertain that each daughter cell gets an even and correct amount of DNA.
The process of DNA replication begins with the unwinding of the double stranded DNA molecule into two single strands of DNA. One strand called leading strand runs from 3'-5' while the other strand runs from 5'-3'. However, DNA replication proceeds in the 5'-3' direction.

The shortcomings or drawbacks of cell theory are: Viruses are considered as acellular entities or organisms that do not have cell machinery, yet they are taken into account as organisms in this cell theory. Matthias Schleiden and Theodor Schwann did not know the mechanism of the cell.
Explanation:
The first phase of Mitosis is _________ . In this phase the DNA condenses down into ________, and the duplicated separate. The second phase of Mitosis is_______ . In this phase the sister chromatids line up on the _______ plate through a push and pull motion as they connect to the microtubule spindle fibers emanating from the ________. The third phase of Mitosis is________ . In this phase the________ (sister chromatids or homologous chromosomes) are pulled apart. The fourth phase of Mitosis is_______ . In this phase the nuclear ________starts to reform and the DNA de-condenses.
MITOSIS:
This question is describing the process of mitosis, a kind of cell division that results in two genetically identical daughter cells. Mitosis consists of four stages namely: prophase, metaphase, anaphase, and telophase etc. PROPHASE is the first stage of mitosis where DNA condenses down into CHROMOSOMES, and the duplicated separate.METAPHASE is characterized by the lining up of sister chromatids at the CELL PLATE through a push and pull motion as they connect to the microtubule spindle fibers emanating from the CENTROSOME. ANAPHASE is the third stage of mitosis in which duplicated chromosome/sister chromatids are pulled apart into opposite poles. The fourth stage is TELOPHASE where the NUCLEAR MEMBRANE starts to reform and the DNA de-condenses.Learn more at: https://brainly.com/question/3327479?referrer=searchResults

At one time, Chondrichthyes were thought to have diverged from other vertebrates before the evolution of bone. Now we have concluded that the Chondrichthyes diverged after the evolution of bone had started. What does this change demonstrate about the evolution of fishes
Answer:
The correct answer would be - Characteristics can be lost in evolution.
Explanation:
The new evidence helps in developing a new hypothesis. In this case, new evidence proved that the Chondrichthyes diverged after the evolution of bone had started instead of before the evolution started. This process called atavism where an ancestral genetic trait reappears after having lost. This leads to loss of the traits in the evolution
This can take place by knocking the mutation out to overriding the gene by the old gene or overriding the new trait by the old trait during the evolution period.
At one time, Chondrichthyes were thought to have diverged from other vertebrates before the evolution of bone. Now we have concluded that the Chondrichthyes diverged after the evolution of bone had started might be their characteristics lost in evolution according to atavism.
What is atavism?
Recurrence in an organism of a trait or character typical of an ancestral form and usually due to genetic recombination. This leads to the loss of the traits in the evolution.
Hence, Chondrichthyes diverged after the evolution of bone had started might be their characteristics lost in evolution according to atavism.

What is chromosome ?
A chromosome is a thread-like structure present in the nucleus of cells such as plant, animal and human cells and it is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins.
It is composed of three components, DNA, proteins and RNA, amount of the DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and small amount of RNA from 1 to 10%.
Two types of protein present in DNA such as histone and non-histones proteins, histone constitute large amount (90% of total protein), whereas non-histone is present in small amount (around 10% of total protein).
The histone protein is basic, whereas, the DNA is acidic, so it can be neutralized; DNA in chromosome is present in two forms such as Euchromatin and Heterochromatin.
