What "REVOLUTION" mentioned in the video had members seeking to overthrow and change all aspects of society to model the rationale thoughts of Enlightenment? Group of answer choices France Englan Spain Portugal
Answer: France
Explanation:
The French Revolution began in 1789 and was based on the High Enlightenment vision that called for an overthrow of old authorities such as the monarchy, replacing it with a leadership that was more reflective of the will of the people and changing all society to be more rational in operation such that liberty and equality were prominent virtues.
The intentions were good but the execution saw much blood and violence and led to different factions taking control of the Government to lead the French in a manner they thought best. All this ended in 1799 however, when Napoleon Bonaparte took power.

Answer: Cells
Explanation:
The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems. The function of an organ system depends on the integrated activity of its organs.
What type of epistasis between locus A and B could be explained by the following biochemical pathway? Select one: a) dominant/recessive epistasis b) duplicate genes with cumulative effect c) duplicate recessive epistasis d) single dominant epistasis e) single recessive epistasis f) duplicate dominant epistasis
Single dominant epistasis between locus A and B could be explained. Hence, option D is correct.
What is epistasis?Epistasis is a situation in genetics where the outcome of a gene mutation depends on the presence or absence of mutations in one or more additional genes, referred to as modifier genes, respectively. To put it another way, the outcome of the mutation depends on the genetic context in which it arises.
The relationship that exists between baldness and hair colour is an illustration of epistasis. A gene for red or blond hair would be epistatic to one for complete baldness. The genes for hair color and baldness are antagonistic to one another. The effects are non-additive since the hair colour genes are superseded by the baldness phenotype.
Epistasis gene interactions can be classified into the following six categories: dominant, dominant inhibitory, duplicate dominant, duplicate recessive, polymeric gene interaction, and recessive.

The reason that men who have enlargement of the prostate gland experience urinary symptoms is:_______.A. The prostate gland is part of the urinary system.B. The prostate gland presses on the urethra.C. The prostate gland blocks the bladder.D. The prostate gland surrounds the bladder neck and the urethra.
Answer:
B. The prostate gland presses on the urethra
Explanation:
Benign prostatic hyperplasia (BPH) is caused by the proliferation of prostatic cells, which leads to the inflammation of this gland, squeezing the urethra (i.e., the tube where urine passes) and ultimately reducing the flow of urine. BPH is a chronic condition progressive with age, thereby it is associated with old men. Although in principle BPH isn't dangerous, high pressure on the urethra may lead to incomplete emptying bladder and infections in the urinary tract.
Which of the following constitutes the basic structural organization of life?
A) species living in an environment
B) cells that make up tissues and structures
C) cell organelles that combine to form nuclei D) weather conditions in a habitat
"Cells that make up tissues and structures" is the statement that best describes the basic structural organization of life.
What is the basic structural organization of life?It is the internal organization of living beings that corresponds to cells, tissues, organs and systems.
Characteristics of the basic structural organization of lifeThe cell is the structural and functional unit of life that carries out all the processes that make the constitution of vital transformations possible.According to their functions and needs, the cells group together and form tissues, structures with similar cells that perform the same function, ultimately constituting a complex system that is the organism.Therefore, we can conclude that the cell is the basic, structural and functional unit of living beings; the simplest unit that can exist as an independent living system.

Which element has fewer than four dots in its electron dot diagrams?
O arsenic (As)
sulfur (S)
krypton (KI)
O gallium (Ga)
Answer:
O gallium (Ga)
Explanation:
Your Welcome;)
The element that has less than four dots in its dot structure is gallium.
What is Lewis structure?The term Lewis structure has to do with the arrangement of outermost electrons in an atom. The Lewis structure consists of the symbol of the element as well as the number of electrons in the outermost shell shown as dots.
Gallium is a member of group 13 hence it has three electrons in its outermost shell. Therefore, gallium has less than four electrons in its dot structure.

Fats composed of fatty acids that have double bonds in the fatty acids and have fewer than the maximum number of hydrogen atoms are:_______.
Answer:
The options are
A. Saturated
B. Liquids at room temperature
C. Solid at room temperature
D. Generally found in animal fats
E. Made of glycerol plus two fatty acids
The answer is B. Liquids at room temperature
Explanation:
Fats composed of fatty acids that have double bonds in the fatty acids and have fewer than the maximum number of hydrogen atoms are liquids at room temperature.
This is because the deficiency in the maximum number of hydrogen atoms makes reduced the high bond strength synonymous with solids. This is why the lipids are known to be liquids at room temperature.
Ester of the fatty acids are called fats and are a part of the diet. The hydrogen atom in the fats when less than the maximum is liquid at room temperature.
What are fatty acids?Fatty acids are the component of fats that can be saturated and unsaturated depending tin the bond and the number of hydrogen atoms. They provide energy to the muscle and the organs of the body.
The fats that contain a single bond and a maximum number of hydrogen atoms bonded are called saturated fats, they are solid at room temperature.
The fats that contain double bonds and fewer hydrogen atoms bonded in the fats are called unsaturated fatty acids, they are liquid at room temperature.
Therefore, unsaturated fats are liquid at room temperature.

Answer:
The stamen of a flower — the part that produces pollen — consists of a slender stalk, called a filament and an anther. The filament supports the anther, which is where pollen develops. The word filament is from the Latin word filum, which means "thread." Filament, in fact, can be a synonym for thread.
Answer:
A filament is the slender threadlike object or fibre, especially one found in animal or plant structures.
a filament can also be defined as the slender part of a stamen that supports the anther.

If a pea plant's alleles for height are tt, what is true of its parents?
A. Both parents were tall.
2 Pts
B. Both parents were short.
C. Both parents contributed a recessive allele.
А E
D. Both parents contributed a dominant allele.
Answer:
C
Explanation:
tt is a recessive allele so it can only be tt if the parents were both tt&tt or Tt&Tt
Answer:
C.
Reason:The plant got it's tt alleles from it's parents, so they would have had to have the recessive alleles to pass it down. This does not necessarily mean that the plants were short, though, as parent plants who both had Tt alleles would have had a chance to have an offspring with tt alleles also.
