States of tension or a rousal that arise from a biological need and are unlearned are called drive.
An unlearned, or primal, drive is a state of tension (arousal) that results from the disruption of an organism's homeostatic condition. Food can be consumed to lessen a hunger drive, which is an a roused state brought on by hunger. Driving less leads to the restoration of equilibrium. Therefore, drives can be viewed as the result of a physiological requirement that an organism is compelled to lessen or eradicate. Learning theorist Clark Hull created an equation to demonstrate the connection between motivation and learning. It is the intensity of a person's need determines the intensity of their drive

Prokaryotic cells generally have a higher surface area to volume ratio than eukaryotic cells.
Answer:
true I think I just guessed
TRUE : Prokaryotic cells generally have a higher surface area to volume ratio than eukaryotic cells
Eukaryotic cells are larger and complex when compared to prokaryotic cells which makes its surface area to volume ratio to be smaller than that of prokaryotic cells. cells are classified based on the arrangement of their cell structures.
Prokaryotic cells are found in smaller organisms like Bacteria while Eukaryotic cells are found in larger organisms like Humans and Plants.
Hence we can conclude that based on the complexity and size of the Eukaryotic cell, the prokaryotic cells generally have a higher surface area to volume ratio.

What is the the process responsible for the synthesis of proteins and mention the cellular structure where the genetic program responsible for this synthesis is located.
Answer: Translation
Explanation:
During the transcription the double stranded DNA act as a separate template strand to produce mRNA molecule. The mRNA molecule encode for amino acid chain that collectively forms the protein. The ribosomes are the sites of protein synthesis the mRNA get attached to the ribosome. Within the ribosome the rRNA molecule instruct the catalytic steps for the synthesis of protein. The amino acid sequence or chain gets stitched together to form the protein.

Explanation:
1. His symptoms consist of difficulty walking and an abnormal gait (pattern of movement such as walking, running, etc)
2. a. one purpose of the blood test was to test his creatine kinase enzyme to see if there were any medical conditions connected to the way he was walking and why it was abnormal
b. the other purpose is to be sure that he has something wrong with his gait. If he does have a medical condition, it was best to see if he had it early on to treat it faster
3. the function of dystrophin gene connects to the cytoskeleton of a fiber which has to do with brain function; we need that to walk. For DMD, that is a condition that alters the way people walk.
4. DMD is inherited from family's genes, so he got it from his birth family probably from his dad's part of the family as DMD effects men more than women
5. It is pretty likely as this medical condition is inheritably passed on. It is likely that his grandchild will get DMD

Arrange the following concepts from simplest to most complex: Chromosomes, DNA, Genome, Gene
Answer:
DNA -> Gene -> Chromosome -> Genome
Explanation:
A genome is an organism's complete set of DNA including all of its genes. Each genome contains all of the information needed to build and maintain that organism. Chromosomes are the threadlike structures located inside the nucleus of animal and plant cells. A gene is the basic physical and functional unit of heredity.
The material and components that are vital for the growth and functioning of an organism that gets inherited from parent to offspring are the components of genetic information.
From simplest to complex they are arranged as:
DNA ⇒ Gene ⇒ Chromosome ⇒ Genome
DNA is the deoxyribose nucleic acid and is the genetic material that transports the instruction for development and function for growth. Gene is a unit of hereditary that codes for gene products.DNA molecules packed as a thread-like structure is called chromosomes.The entire set of genes that pass from parent to offspring is called the genome.To learn more about genome and genes follow the link:

Answer: The most problem is likely with chromatin
Explanation:
If a chromosome comes apart because it is not well attached at the center, The most problem is likely with chromatin.
What is chromosome ?
A chromosome is a thread-like structure present in the nucleus of cells such as both prokaryotic and eukaryotic cell 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.

Specialisation in the knowledge society and its need
Posted by Bernardo Lajus on Mon, 01/07/2013 - 11:54.
Contemporary society is characterized by globalization. The information and the speed with which they reach society amaze anyone who has experienced the 1980s and 1990s. Because of the technology and facilities it brings, the recipients of this information become increasingly demanding, in every way. Demanding with you, with others, with things, with everything, making the world so demanding, to the point that services and information are insufficient, exhausting, poor.
Because of this, the world specializes. The professions have gained new directions, new perspectives. The courses that were previously generic, such as engineering, law, medicine, became insufficient and were gaining tributaries. If before the general practitioners of mechanical engineering and law realized the professional demand, over the years and the evolution of society, it required professionals to become specialists, creating branches and opening possibilities.
Today, specialists, masters and doctors are essential for the rapid development of society, required everywhere. Despite the harm spawned (such as time demanded, or "knowing much about little), specialization in the knowledge society brings inegulable benefits. The creation of new jobs, the deepening of knowledge and the quality of services makes society evolve even more.
Thus, although the human being, in his individuality, is not expanding his way of knowing, but rather reducing himself to specificity, society as a whole plunges into a profound expansion of knowledge, bringing this to everyday life, from the most trivial to the most complex of works, specialization is necessary and beneficial.
