In 1953, Stanley Miller and Harold Urey built a model of Earth's early
atmosphere by mixing gases that were thought to have been there. They
exposed the gases to an electric current to simulate lightning. The liquid that
condensed during the experiment contained amino acids.
What was the significance of their results?
A. Miller and Urey showed that lightning was necessary for life to
form on Earth.
B. Miller and Urey showed that spontaneous generation was
possible.
C. Miller and Urey showed that inorganic compounds could combine
to form the building blocks of living cells.
D. Miller and Urey showed that all life evolved from a single common
ancestor.
Answer: C. Miller and Urey showed that inorganic compounds could combine to form the building blocks of living cells.
Explanation:
The Miller and Urey were the two scientists who created the atmospheric conditions that were expected to be present on primitive earth. They demonstrated that several organic compounds have been formed spontaneously from the inorganic compounds like water, ammonia, methane and others.
The exposure of mixture of inorganic compounds by the lightening lead to the formation of organic molecules like amino acids which are the building blocks of life. This was similar to the penetration of earth atmosphere by UV radiation producing the organic compounds from inorganic molecules.
HOW ARE VIRUSES DIFFERENT FROM OTHER MICROBES
Answer:
All viruses have is a protein coat and a core of genetic material, either RNA or DNA. Unlike microbes, viruses can't survive without a host. They can only reproduce by attaching themselves to cells. In most cases, they reprogram the cells to make new viruses until the cells burst and die.
Explanation:

Could someone help me match the types of resources with their descriptions ?
Answer:
They can be reproduced on a human time scale- Renewable resources
They take millions of years to form- Nonrenewable resources
They are produced naturally- both Renewable and Nonrenewable resources
They are extracted by mining- Nonrenewable resources
Their use as energy source is increasing because they reduce pollution- Renewable resources
Explanation:
1. Renewable resources are a type of natural resources that are replenished or reproduced by natural processes on a human time scale. Hence, they are inexhaustible as opposed to the Nonrenewable resources.
2. Nonrenewable resources are those resources that gets used up quickly than they can be replenished. Hence, they are exhaustible. These resources takes millions of years to form, and will take more to be replenished.
3. Both the renewable and Nonrenewable resources are found naturally i.e. they are exploited in their natural state, with no man forming them.
4. The Nonrenewable resources like crude oil, natural gas, coal etc. are found embedded in the Earth crust either in solid, liquid or gaseous form and are extracted by humans via MINING.
5. Renewable resources such as solar, wind, etc are increasingly used as sources of energy because of their eco-friendly characteristics. This means that they contribute less to emission of pollutants, that lead to global pollution. Hence, the reason renewable source of energy are called "Green or Clean" sources of energy.

A. Cellular respiration shuts down during the day while
photosynthesis occurs, and then photosynthesis shuts down at night while cellular respiration occurs.
B. Both cellular respiration and photosynthesis rates cycle up and down in similar patterns over a 24-hour cycle.
C. Oxygen levels oscillate as the light-dependent reactions of photosynthesis take place during daylight and light-independent reactions take place during nighttime.
D. Cellular respiration remains constant, while photosynthesis cycles between a very high rate in the light and zero in the dark.
Answer:
Option-D
Explanation:
Cellular respiration and photosynthesis are the two main physiological process which drives the life on Earth. Photosynthesis process leads to the synthesis of Glucose whereas Cellular respiration breakdown the Glucose molecule to form ATP molecules.
In plants, the photosynthesis process occurs in green leaves whereas cellular respiration occurs in every cell of the plant inside the mitochondria.
In the given question, the graph shows:
1. The absorption of oxygen till 6 am which is required during cellular respiration.
2. After 6 am, the level of oxygen production becomes more than oxygen absorption till 6 pm.
3. After 6 pm, no sunlight is available therefore photosynthesis does not occur. After this, the rate of cellular respiration increases that is oxygen is taken in.
Thus, Option-D is correct.
Homologous structures are assumed to: • Have different functions •Have the same evolutionary origin •Have the same function •Have different evolutionary origins
Answer:
Have the same evolutionary origin
Explanation:
Predicting the evolutionary relationship between organisms require certain structures, which are used as evidence. These structures can either be homologous or analogous.
Homologous structures are those structures of organisms that have a similar embryonic or evolutionary origin i.e. share common ancestors. For example, the wings of a bat and the arm of humans are homologous structures because they are found to be from the same evolutionary origin. Although, they appear different and perform different functions but using genetical means (DNA), they have been found to share a common ancestor.
On the other hand, analogous structures are structures that perform similar functions and are physically similar but they evolved from different evolutionary origins.

A friend has come over to your home and flips through your psychology book. She notices the chapters
you have to read for this week which are heavily based on biological function, the brain and our senses.
She states: "I don't understand why you are reading so much on physiology and biology. I thought you were
taking a psychology class".
Given what you have read this week and your understanding of our brain, sensation and perception, how
would you explain to your friend the intricate connection between brain, sensation, perception and our
behavior and cognition. In what specific ways might knowing our physiology help us understand how our
mind works. In other words, in what specific way might knowing the brain and sensation help us
understand our daily experiences.
Please use specific examples of brain parts and sensation to connect the mind and brain.
Answer:
Please see below
Explanation:
The physiology of the brain is closely related to how we think and feel. The limbic system in the brain, for example, is the center of all our emotions. Understanding how this part of the brain functions will greatly help in understanding the psychology of the human being. There are certain hormones that have an affect on our moods and behavior so it is important to gain knowledge of physiology and genetics in order to grasp the science behind emotional responses, memory etc.

Which of the following is true of sound waves?
A. Sound waves are transverse waves.
B. Sound waves can only travel through fluids.
C. Sound waves are electromagnetic waves.
D. Sound waves require a medium in which to travel.
Answer:
D. Sound waves require a medium in which to travel.
Explanation:
Sound waves need to travel through a medium such as a solid, liquid, or gas.The sound waves move through each of these mediums by vibrating the molecules in the matter. The molecules in solids are packed very tightly. Liquids are not packed as tightly as solids. And gases are very loosely packed. The spacing of the molecules enables sound to travel much faster through a solid than a gas. Sound travels about four times faster and farther in water than it does in air.
A type of wave that releases energy due to vibration and is acoustic is called a sound wave. Sound waves require a medium to propagate or travel.
What is the property of the sound waves?For a sound wave to travel a solid, liquid or gaseous medium is required. The molecules of the medium vibrate for the sound waves to travel. The sound waves travel differently in these three mediums.
The arrangement of the particles of the solid medium makes the sound waves travel fastest compared to the liquid and then the gaseous air molecules. The solid has more closely packed molecules than the liquids and gas.
Therefore, option D. sound waves require a medium to travel is true.

and a radius of 13 cm? Round your answer to the
nearest tenth.
VE
cm)
27 cm
113 cm
Answer:
4780.3 cm^3
Explanation:
A cone is a three-dimensional shape and its volume can be calculated using the formula:
V = 1/3 πr^2h or πr^2h / 3
Where V= Volume of cone (cm^3)
r= radius (cm)
h= height (cm)
π= constant (22/7)
In this question, the values of r and h are 13cm and 27cm respectively.
Hence, to calculate the volume of the cone, we say;
V = 1/3 × 22/7 × 13 × 13 × 27
V = 100,386 / 21
V = 4780.2857142857
4780.285 to the nearest tenth is ~ 4780.3
Therefore, 4780.3cm^3 is the volume of the cone.
