In the fourth century BC, Aristotle observed a phenomenon in which he saw a circular shadow on the Moon. He argued that Earth was a sphere based on this observation. What phenomenon caused the shadow on the Moon? *
a solar eclipse
a lunar eclipse
a spring equinox
a summer solstice
Answer:
a lunar eclipse
Explanation:
The shadow that Aristotle saw was caused by a lunar eclipse. At that time the sun, earth, and the moon nearly straight alignment caused the Earth's shadow to be reflected on the moon. This shadow is what ultimately led Aristotle to believe that the Earth was a sphere. This should not be confused with a solar eclipse which is similar but instead the sun, moon, and earth align in that order which causes the moon to completely block the sun to anyone on earth.
What is true about cardiac (heart) cells compared to brain cells?
Different DNA which make different proteins
Same proteins being used to create different DNA
Same DNA being used to make different proteins
Different proteins used to create different DNA
Answer:
Same DNA being used to make different proteins
Explanation:
Cells of all living organisms contain the genetic material called DNA. One of the characteristics of multicellular cells is the ability of their cell to DIFFERENTIATE i.e. form specialized cells during division.
However, it is worthy to note that all cells possess the same DNA but some of the genes contained are expressed into proteins while others are not. This leads to why cells that contain similar DNA make different proteins and perform differently.
In this case, cardiac (heart) cells and brain cells contain the same DNA but due to the expression of some genes and repression of others, they are able to differentiate into different cells.

What is phagocytosis in regard to the immune system of humans?
Answer:
Phagocytosis is the process of introducing larger particles into a larger cell. The process takes place by twisting the cell membrane of the "host" and enveloping the particles with a phagocytic bubble. Leukocytes use phagocytosis to take in and incapacitate bacteria that enter our body, so phagocytosis plays an important role in the immune system, as it prevents harmful cells from affecting humans.
Answer:
the process by which neutrophils ingest a bacterium
Explanation:
Neutrophils ingest bacteria via a process known as phagocytosis, or "cell eating." (also, I took the quiz)

Describe the nervous response pathway when you taste something bad and spit it out. Using these keywords: stimulus, chemical receptor, sensory neurone, relay neurone, motor neurone, muscles, response, electrical impulse, chemicals
Answer: Nervous system includes the brain which is the main center for interpreting various stimuli in the environment.
Explanation:
The nervous system detects the food stimulus. The chemical receptors present in the tongue detects the chemicals present in the food. These receptors send the impulses to the sensory neuron present in the brain. The impulse is then transmitted to the relay neuron then to motor neuron and then finally to the muscles of the mouth. The muscles of the mouth help in spitting the food as the sensory neurons help in detecting the taste of the food and find it either edible or non-edible.
How have human activities effected the air in earth’s atmosphere?
Answer:
Human activities have had a negative impact on Earth's atmosphere.
Explanation:
Human activities, since the Industrial Revolution, have gradually been having more and more influence on Earth's atmosphere. As more and more the economies have developed, the bigger and bigger the output of gases into the atmosphere. The gases that are released into the atmosphere are mostly greenhouse gases, but there are also some that are highly toxic.
This has contributed to a sharp increase in CO2 levels in the atmosphere, which is speeding up the process of global warming, and that can have devastating consequences for life on Earth. Also, some of these gases managed to cause huge damage to the ozone layer, the layer that protects us from UV radiation, and if the ozone is gone, every complex organism will be gone as well.

prepare a question aire to know about interdependence between the biotic and abiotic component
Answer: The biotic components of the environment are the living which beings that interact with the abiotic component of the environment. Abiotic components are non-living like air, water, soil, atmosphere, and others. The biotic components require abiotic components for their survival and the abiotic components get recycled due to the utilization by the living beings.
Explanation:
Questionnaire that can be related with the interdependence of the biotic and abiotic component:
1. How abiotic components are related to biotic components?
2. How abiotic components affect the functioning and survival of the biotic components?
3. What will be the impact on biotic components if all the abiotic factors are removed from their surrounding environment?
4. How water cycle gets disturbed due to deforestation?
5. How carbon cycle gets affected by the deforestation and pollution increases in the region of deforestation?

Explanation:
The trait for tall pea plants is (T) and the trait for short pea plants is (t). The trait for smooth pea plants is (R) and the trait for wrinkled is (r).Two plants are crossed producing a F1 generation of plants with 612 tall and smooth pea plants and 188 short and wrinkled pea plants.What would be the most likely genotype of the parental generation?
Answer:
P generation = TtRr × TtRr i.e both parents were heterozygote for both traits
Explanation:
This question involves two genes encoding the height and texture in pea plants respectively. The alleles for tall and smooth pea traits are dominant over the alelles for short and wrinkled traits.
According to this question, two plants are crossed to produce F1 offsprings as follows: 612 tall and smooth pea plants and 188 short and wrinkled pea plants.
First, we turn this derived number of offsprings into ratio by dividing by the smallest number (188)
612/188 : 188/188
3.25 : 1
Approximately; we can say this is 3 (tall and smooth) : 1 (short and wrinkled)
Based on this ratio, which was got by Mendel for his F1 offsprings when he crossed pea plants, the parental generation has a heterozygous genotype (TtRr).

What is a convergent boundary?
Answer:
A convergent boundary is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction. The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone.
Explanation:
The respiratory rate times the tidal volume corrected for the dead air space in the lungs is the __________.
a. vital capacity
b. respiratory minute volume
c. pulmonary ventilation rate
d. alveolar ventilation rate
e. external respiration rate
Answer:
d. alveolar ventilation rate
Explanation:
Alveolar Ventilation rate (AVR) refers to the rate of airflow that reaches the alveoli which is available for gas exchange with the blood in a given unit of time. AVR is generally calculated as the amount in millimeters of air expired that equilibrates (i.e., exchanges) with alveolar gas per min unit (ml/min). AVR is affected by breathing frequency, tidal volume ( i.e., the normal amount of air between inhalation and exhalation), and the amount of dead space in the lungs.
Explicitly explain how a living organism obtains energy after eating.
Answer:
Explanation:
Tiny bits of the food you ate break down into a simple sugar called glucose. In your cells, energy from the sugar is released when oxygen and glucose combine in a reaction. The reaction produces water, carbon dioxide, and energy in the form of ATP. This chemical process is happening all the time in your cells.
When human undergo anaerobic respiration , they

Explanation:
2. Name a microbe that lacks a cell wall and would find hypotonic environments detrimental.
Answer:
I so I am also a bit confused, but I hope this could answer your question!
Explanation:
The bacteria possess a cell wall composed of peptidoglycan molecule formed by the amino acids called murine. The bacterial cell wall helps in the survival of the bacteria in some extreme condition like when placed in a hypotonic solution.
The hypotonic solution is formed when it has low solute concentration and high water amount when compared. When the bacterial cell will be placed in hypotonic solution then the water will move inside the cell down the concentration gradient as a result of which the bacterial cell will swell but will not burst.
This happens as the cell wall contains expansin protein which allows the cell wall to expand and provides rigidity to the cell.
