He might draw the conclusion that,
By releasing chemicals known as hormones and neurotransmitters, respectively, as a form of communication, the endocrine and neurological systems both regulate, coordinate, and integrate many physiological processes and bodily activities. A stimulus activates the neurological and endocrine systems, which then send messages and produce responses.
The endocrine and neurological systems are different:
Endocrine glands secrete hormones that act for a much longer period of time than the neurological system's ability to produce a neural response. Hormone action moves more slowly than neuronal response. A nerve or neural impulse may move through the body almost instantly and in a matter of seconds.
While the neurological system employs electrical impulses to transfer signals across neurons for signaling pathways, the endocrine system uses chemical signals or hormones to accomplish so. The neuronal reactions are transient and reversible, whereas the hormonal impulses are permanent.

After three months of training, during which he was able to lift increasingly heavier weights, abe’s arm and chest muscles became much larger. What happened to the fibers in these muscles?.
Muscle Hypertrophy is what causes the muscle to grow.
To follow Hypertrophy 'Muscle under Stress' is an important component while working out. It is directly proportional to the growth of muscles. These are three mechanisms for muscle growth.
Muscle Stress: In order to grow muscle, it should be kept under a lot of tension using weights and the tension should be more than the body is adapted to. This is a concept of Progressive Overloading your muscle.Muscle Damage: After working out, Muscle Fibres get torn up. This local muscle damage causes a release of inflammatory molecules and immune system cells that activate satellite cells to jump into action.Metabolic Stress: It causes the cells around the muscle to swell. This is from the addition of muscle glycogen which helps muscle and the connective tissue to get swollen up. It is often referred to as 'PUMP'.After Working out, due to tears in muscle fibers, the protein-synthesizing rate should be high which is absorbed by the muscle and causes to muscle fiber repair and grow.

Transcription is the synthesis of RNA using DNA as a template.
What is transcription?Transcription involves the copying of a DNA fragment into RNA.. Messenger RNA is the term for DNA segments that are translated into RNA molecules that can encode proteins. Non-coding RNAs are RNA molecules that contain copies of other DNA sequences. Even with the most sensitive approaches, mRNA, which makes up only 1%–3% of total RNA samples, cannot be easily detected. Less than 2% of the human genome can be transcribed into mRNA, but at least 80% of mammalian genomic DNA can be actively transcribed (in one or more types of cells), with the majority of this 80% being ncRNA.

What would happen to both acid-fast and non acid-fast cells if no heat was used in the staining procedure?
When both acid-fast and non-acid-fast cells if no heat was used in the staining procedure the cell wall becomes hydrophobic and impermeable. It happens because most stains and chemicals in aqueous material are in the absence of heat due to the waxy, destructive structure. It's possible that we neglected to heat the solution or decolored it excessively.
Acid fast stains are used to differentiate acid-fast organisms such as mycobacteria. Mycolic acids make up a large portion of the cell walls of acid-fast bacteria. Nonacid-fast bacteria will stain blue/green with the Kinyoun stain, while acid-fast bacteria will stain red. Non-acid fast bacteria are those that decolorize and lose their carbol fuchsin red color.
The primary difference between acid-fast and nonacid-fast bacteria is that acid-fast bacteria resist decolorizing by acid after receiving a stain whereas non-acid-fast bacteria are readily decolorized by acid after staining.

Human dna has two types of chromosomes. what are these two types, and how do they differ from each other? would you expect both types to appear in the dna you extracted?
Yes, Human DNA have two types of chromosomes that are Autosome and Allosomes/ Heterosomes
Human Chromosomes are Found:
Before cell division, chromosomes are widely distributed and challenging to find. The chromosomes may be observed clearly during cell division, photographed, and their morphology, size, and shape analyzed. Autosomes and sex chromosomes are two groups of chromosomal types. Below is an explanation of these types:
The autosomes
The structures that house the genetic material are called autosomes. They do not include details about reproduction and sex identification. The male and female species of humans are the same in both sexes. In humans, there are 46 (2n) chromosomes. There are 44 pairs of autosomes among the 46 chromosomes, and they each provide data on the phenotypic traits.
Heterosomes and allosomes
The size, shape, and behavior of the sex chromosomes known as allosomes differ from those of autosomes. In humans, there are two allosomes. The sperm can include either the X or Y chromosome, and the X chromosomes are present in the ovum. These chromosomes aid in determining the progeny's sex. If both the mother and the father contributed an X chromosome, the child would be female (XX). A male child is born if the offspring inherits one X chromosome and one Y chromosome from the parents (XY). Simply said, the father's donation of an X or Y chromosome aids in determining the gender of the child.
