“The study of cells had its birth with the invention of microscope, but it became a product of the 19th century.” What does this mean?
The invention of microscope led the scientists to look at the tiniest of the things that human eyes were not capable of. A Dutch glassmaker named Zacharias Janssen, invented the microscope which turned out to be the most important invention in the scientific history.
What is a Cell?
In 1665, It was Robert Hooke who came up with the name suggestion called CELL.The word Cell is derived from the Latin word Cella, meaning, Small Room/Chamber/Compound.Cells are known as the smallest unit of Life, that makes up all living organisms and the body tissues.Cells basic function is to provide a structure to the body by combining tissues and extracting nutrients from food and then converting it into energy form to carry out all the basic functions in a living organism.How did microscope became a product of the 19th century?
Even though microscope was invented in the 16th century, but It came in action more in the 19th century.Scientists were amazed by the fact that now the tiniest of tissues can be seen that no ordinary human eyes had ever been able to see before. Major improvements were initiated to the microscopes in the 19th century by the scientists .For example, Achromatic Lenses were implemented, in which the colors can be seen exactly as they are without dispersing it into its diverse constituent colors.And that is how in the 19th century, the development of cell theory was introduced.To learn more about the Microscopes, check this link:

What part of the cell cycle has been disrupted to allow for the formation of cancer cells?.
The formation of cancer cells occurs in the interphase cell cycle which is disrupted, precisely when DNA synthesis is in the S phase.
How does the cell cycle affect cancer?In many cancer cells, the number of chromosomes changes so that there are either too many or too few chromosomes in the cell. These cells are said to be aneuploid. Errors can occur during DNA replication resulting in mutations and possible development of cancer.
Cancer is the result of uncontrolled cell division caused by damage to the mechanism that regulates the cell cycle. Loss of control begins with a change in the DNA sequence of a gene that codes for one of the regulatory molecules. Incorrect instructions cause the protein to not work as it should.
Cells that progress through an uncontrolled cell cycle may eventually form a malignant tumor, in which masses of cells grow and divide uncontrollably, then develop the ability to spread and migrate throughout the body.

Using a pedigree autosomal recessive traits, such a cystic fibrosis, are easy to follow through the generations. Explain the inheritance of cystic fibrosis in two children of the third generation in
Cystic fibrosis in the two children of the third generation is inherited in an autosomal recessive inheritance pattern.
Autosomal refers to the 46 chromosomes are present. Among them, 44 are the non-sex chromosome & 2 are the sex chromosomes. Chromosomes are the untangled phase of DNA before cell division.
The 22 pairs of chromosomes don’t play a role in determining the sex of the human body. They are responsible for the structure of the body. They provide some unique patterns to the body.
On the other hand, the sex chromosomes are responsible for determining the sex of a human. There are two types of sex chromosomes. One is the X chromosome & another is the Y chromosome.
The chromosomes are referred to as genes when they are about to get divided. The genes can be either dominant or recessive on one generation. Therefore, in the given condition, it is referred to as autosomal recessive inheritance pattern.

autocrine stimulation is the ability of cancer cells to do what?
Answer: produce and to respond to their own growth factors
Explanation:
how did these factors affect evolution in this population? (i.e. selection, mutation, genetic drift, migration.)
Mutation, gene flow, and genetic drift are random tactics with respect to variation they exchange gene frequencies without regard for the outcomes that such modifications may have inside the potential of the organisms to survive and reproduce.
Random genetic drift describes the stochastic fluctuations of allele frequencies due to random sampling in finite populations. over the years, genetic glide can lead to fixation or loss of genetic variants, thereby systematically putting off range from a population.
Migration will exchange gene frequencies by bringing in greater copies of an allele already within the populace or by bringing in a new allele that has arisen by means of mutation. due to the fact mutations do not occur in every population, migration might be required for that allele to spread for the duration of that species.

What is mitosis easy definition?
A eukaryotic cell's nucleus divides in two during the process of mitosis, which is followed by the division of the parent cell into two daughter cells.
What are the feature of Mitosis?Two daughter cells are created from the parent cell during each round of cell division. As a result of the identical chromosome number in the parent and daughter cells, the cell is sometimes referred to as equational cell division. In plants, the process of mitosis promotes the growth of the plant's vegetative parts, such as the root and stem tips. In this process, segregation and combination do not take place.

mendel found that yellow pea pod color (g) was dominant to green pea pod color (g). for each of the crosses below, what percentage of offspring are expected to be yellow?
GG x GG = 100% because both parents have dominant homozygous allele G.
Gg x Gg= 75% because both the parent are heterozygous. The result of yellow offspring is GG:Gg:Gg:gg.
gg x gg = 0% because both the parent are homozygous recessive allele g after cross only green offspring would be seen.
Why is Mendel credited with founding genetics?Through his research on pea plants, Gregor Mendel discovered the fundamental ideas of inheritance. He came to the conclusion that each pair of genes is inherited separately from each parent.
The first rule of inheritance is the dominance principle. Only the dominant traits in the phenotype will be passed down to hybrid offspring, according to the law. Recessive traits are those alleles that prevent the occurrence of a trait, whereas dominant traits are those alleles that cause the occurrence of a trait.

Explain the role of water potential in the movement of water from soil through the plant and into the air.
Water potential, which determines the potential energy present in waters and controls how water flows through plants, For photosynthesis to occur, plant use water uptake to move water to the leaves.
What is water potential?The energy needed to move an infinitesimally small amount of water first from sample to a comparative pool or pure free water is known as the water potential. Controlling the blood's water potential is referred to as osmoregulation. The blood is difficult because it contains so many ions, proteins, and other things.
Why does water potential exist?Pressure, gravity, and zeta potentials are a few variables that have an impact on water potential. A system's maximum potential energy grows with increasing pressure potential (p); a system's maximum possible energy falls with decreasing p.

When the population is 3000 organisms, the slope will be an inclined graph and when the population is 1000 organisms the graph will be a parabola in case of exponential growth.
Exponential growth is the growth when organisms or microorganisms grow in a constant number in interval of time. Exponential growth is also known as log phase growth.
The cells during exponential growth phase are at their healthiest state and are thus used for biochemical and physiological studies. During exponential growth, the cells divided at their maximal rate given the genetic potential, and the environmental conditions.
Mathematically, exponential growth can be explained as the population density is equal to the initial growth added with time of the generation.
