How is weight affected by the location?
The gravitational pull varies slightly as one moves across the Earth’s surface, depending on latitude and topology, since the Earth isn’t a perfectly round ball.
The further away from the Earth an object is, the lighter it is. At the southern pole of the Earth, an object's mass is slightly greater than its mass at the equator because the Earth's polar radius is slightly smaller than its equatorial radius.
Body weight changes with altitude. Body weight changes as acceleration due to gravity changes. Weight decreases with altitude. The weight of an object changes with altitude.

"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.

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.

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.

Do you think, what is currently being done in your community,
adequately promotes social and environmental justice?
Answer:
a little bit
Explanation:
there are people who do the right thing and they are people who do they wrong things
No I do not think what is currently being done in your community, adequately promotes social and environmental justice.
Social justice refers to when resources are distributed in society in such a way that everyone gets a fair share.
Environmental justice is when everyone in society gets a fair treatment regardless of their demographic characteristics such as race, nationality or even gender.
From a global community perspective, I do not think social and environmental justice are being adequately promoted because:
resources are not being fairly distributed which is why we have poor countries and rich countries as well as billionaires while in some areas some people barely made a dollar a day. people are also being discriminated against everyday based on their races, color, gender and nationality and it does not seem to be ending.In conclusion, more work needs to be done to ensure social justice in the global community.

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.
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.
