In the 1950s, Stanley Miller performed experiments to study the origins of life. He created an atmosphere rich in methane, hydrogen, ammonia, water, and simulated lightning. Which substances were most likely produced during Miller’s experiments?
A. protists
B. bacteria
C. amino acids
D. RNA strands
Answers
Answer:
c. amino acids
Explanation:
The substances most likely produced during Miller's experiments would be amino acids.
In their simulation of the early atmosphere, Stanley Miller was able to obtain a mixture of organic compounds in the broth with the major one being amino acids.
The discovery of Stanley Miller gave further credence to the chemosynthetic theory of the origin of life because amino acids form the building blocks of proteins and proteins are essential for the onset of life.

A. Describe the difference between gradualism and punctuated equilibrium.
B. Describe the conditions under which new species may arise.
C. Explain the difference between allopatric and sympatric speciation.
D. Describe the role of prezygotic and postzygotic barriers in the process of speciation.
Answers
A. Both theories describe the rates of speciation. For Gradualism, changes in species is slow and gradual, occurring in small periodic changes in the gene pool, whereas for Punctuated Equilibrium, evolution occurs in spurts of relatively rapid change with long periods of non-change.
B. New species arise through a process called speciation. In speciation, an ancestral species splits into two or more descendant species that are genetically different from one another and can no longer interbreed.
C. Allopatric speciation occurs when two species are living in separate environments and therefore there is no gene flow between the populations. ... Sympatric speciation occurs when two species are living in the same environment.
D. Reproductive isolation is a mechanism that keeps species from mating with others. Prezygotic isolation prevents the fertilization of eggs while postzygotic isolation prevents the formation of fertile offspring. ... Postzygotic mechanisms include hybrid inviability, hybrid sterility and hybrid "breakdown."

According to paragraph 1, which of the following factors limits the abilities of populations within an ecosystem to survive?
Answers
Answer:
Availability of space, shelter, food, and water
According to paragraph 1, the factor that limits the abilities of populations within an ecosystem to survive is the availability of space, shelter, food, and water that is present in option C.
What are the ecosystem's limiting factors?Ecosystems are composed of living organisms and the nonliving elements with which they interact, including air, water, soil, and sunlight. Within an ecosystem, all organisms have certain requirements for survival, such as the need for space, shelter, food, and water. These resources are often limited within any given ecosystem, which means that populations within the ecosystem are limited in terms of their ability to survive and reproduce.
Hence, the factor that limits the abilities of populations within an ecosystem to survive is the availability of space, shelter, food, and water that are present in Option C.

What are the differences between carnivorous animals and omnivorous animals?
Answers
1. Teeth
Carnivore's teeth are long, sharp and pointed, helpful piercing into flesh. Omnivore's (meat and plant eaters) teeth are similar to that of carnivores. Omnivores have sharp canine teeth at the front of the mouth to cater for meat, and flat molars to allow a grinding action for plant material.
2. Digestive enzymes
As with the herbivore, amylase is contained within the saliva of the omnivore, which also utilises the chewing action to help break down the coarse fibres and carbohydrates that makes up plant material. Amylase is not present within the saliva of carnivores hence the burden of digesting carbohydrates is taken by the pancreas. Long term over loading of the pancreas is associated with insulin resistance and ultimately the failure of the pancreas to produce of insulin as found in type II diabetes.
3. Jaws
The jaws of carnivores are highly muscular and strong, which ensure a firm grip on the captured prey. They have stronger jaws than omnivores.
4. Gut
Usually, the gut of the herbivores is longer than in carnivores, but omnivores have a long gut to capacitate both types of diets. Carnivores gut is not as long as the herbivores and omnivores. Therefore, they get hungry and thirsty more often than herbivores.

A high population of greater prairie chickens once inhabited the prairies of Illinois. The conversion of the prairies into agricultural land caused the chickens to lose their habitat. Studies have concluded that this change greatly reduced the greater prairie chicken population. The habitat loss also resulted in a decrease in the population’s genetic variation.
Which change in the gene pool occurred in the greater prairie chicken population?
gene mutation
gene flow
genetic drift
genetic resistance

The answer is C. genetic drift

Two true-breeding stocks of pea plants are crossed. One parent has red, axial flowers and the other has white, terminal flowers; all of the first generation of the offspring have red, axial flowers. The genes for flower color and location assort independently. If 1,000 second generation offspring resulted from the cross, approximately how many of them would you expect to have red, terminal flowers
Answers
Answer: 750
Explanation:
Based off the first two sentences, we can conclude that red is the dominant allele and white is the recessive allele.
Let's say R = red and r = white.
The genoytypes of the parents are RR and rr. The genotype of the first generation are all Rr
The punnet square for the second generation is:
R r
R RR Rr
r Rr rr
We can see 3/4 crosses give us red. Now we can multiply 3/4 and 1000 to get 750.

What is a similarity between the temperate climate zone and polar climate zone?
A) Both of the climate zones have warm and hot weather and lots of precipitation.
B) In both polar and temperate zones, the temperature of the warmest month is about 18°C.
C) The temperature can get to 0°C in both temperate and polar climate zones.
D) The temperate and polar climate zones both usually have 150 cm of precipitation.
Answers
In both the polar and temperate zones, the temperature of the warmest month is about 18°C. So, the correct option is B.
What are Polar and Temperate zones?Temperate regions are defined as regions with mild temperatures that lie between the subtropical and polar regions where the two regions between the Tropic of Capricorn and the Antarctic Circle or the Tropic of Cancer and the Arctic Circle are called temperate regions.
The polar region is defined as the area around the North Pole or the South Pole, where the North Polar Region consists mainly of flotation and pack ice, 7–10 feet (2–3 m) thick which floats on the Arctic Ocean and is surrounded by land. In both zones, the temperature of the warmest month is about 18°C.
Therefore, the correct option is B.
