How have human activities effected the air in earth’s atmosphere?

Answers

Answer 1

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.

Answer:

1.) The solute molecules will not move between the two sides because the membrane does not have large enough spaces for the molecules to move through. The water molecules will move to the right side because water moves to places of a higher solute concentration.

2.) The right side represents high concentration because it contains the majority of the solute molecules.

3.) The left side represents low concentration because it contains a small amount of solute molecules compared to the right side.

the process of living organisms staying the same

Answers

Answer:

Explanation:

All species of living organisms, from bacteria to baboons to blueberries, evolved at some point from a different species. Although it may seem that living things today stay much the same, that is not the case—evolution is an ongoing process. The theory of evolution is the unifying theory of biology, meaning it is the framework within which biologists ask questions about the living world.

Answer:

Living organisms have an ability to keep a stable internal environment and they maintain to have a balance inside their cells.

Explanation:

Reproduction is the process by which organisms make more of their own kind from one generation to the next.

What are the layers of the earth?

Earth has many different layers based on their arrangements and occurrences. The crust is the first layer of the earth where humans and other organisms live and ranges from 6 -70 km thick. It is followed by the Moho barrier.

The Moho barrier is the layer that separates the crust from the mantle and is followed by the mantle layer where the convection in the tectonic plates leads to earthquakes.

The deepest and the innermost layer is the core where the solid and liquid hot gases are found at very high temperatures. It is very hot and composed of iron and nickel.

Therefore, the matches are 1. c, 2. d, 3. b, and 4. a.

Answer:

d. neurotransmitters that excite or inhibit a neural signal across a synapse

Explanation:

Neurotramniters are molecules that transmit chemical messages from nerve cells by traveling across the synapse to target cells. Some of the most important neurotransmitters include acetylcholine, norepinephrine, dopamine, gamma-aminobutyric acid (GABA), glutamate, histamine and serotonin. Norepinephrine is a neurotransmitter synthesized from dopamine which is involved in the regulation of stress response, sleep, and blood pressure. Norepinephrine, also known as noradrenaline, is an important neurotransmitter involved in stress response and exercise. Finally, acetylcholine is a neuromodulator of the autonomic nervous system involved in attention responses, memory and motivation.

When increasing the size of muscles or building muscle mass ____________. Group of answer choices muscle soreness indicates the muscles are growing delayed onset muscle soreness indicates the muscles are growing lactic acid build up triggers muscles to grow micro tears signal the muscles to grow

Answers

Answer:

A. soreness indicates the muscles are growing

D. micro tears signal the muscles to grow

Explanation:

Muscle soreness is one of the indication of muscles are growing as while doing exercise, some inflammation takes place to get bigger and stronger muscles. Some pain signals are sent by the body to make it feel soreness after intense exercise.

Micro tears signal also indicates muscles growth as after intense workout, a certain amount of soreness is felt by our body and these micro tear signals to repair and replenish the muscle tissue that eventually accumulate to form muscle mass.

Hence, the correct answers are: "A. and D.".

During a 6 month period, 239 cases of pneumonia occurred in a town of 300 people. A clinical case was defined a fever >102oF lasting >2 days with three or more symptoms (i.e. chills, sweats, severe headache, cough, aching muscles/joints, fatigue, or felling ill). A laboratory-confimed case was defined as a positive result for antibodies against Coxiella burnetii. Before the outbreak, 2000 sheep were kept northwest of the town. Of the sheep tested from the flock, 15 were positive for C. burnetii antibodies. Wind blew from the northwest and rainfall was 0.5 cm compared with 7-10 cm during each of the previous three years.

Required:
a. What is the significance of the rainfall?
b. The etiologic agent of the disease is:______
c. This is an example of:_______

Answers

Answer:

a. What is the significance of the rainfall? These bacteria resist desiccation, and its dispersion is favored by winds. A decrease in rainfall means a dryer environment, which the bacteria can resist and makes it easier for the cell to be carried somewhere else by winds.  

b. The etiologic agent of the disease is Coxiella burnetii

c. This is an example of  a zoonosis  

Explanation:

Q fiber Pneumonia is a zoonosis world-widely distributed and of global importance, which etiologic agent is Coxiella bunetti.

Zoonosis: Referred to as the infectious diseases that are naturally transmitted from animals to human beings. Among zoonotic pathogens, there are bacteria, viruses, or parasites. They propagate by direct contact, water, and wind, among others. These diseases represent a global importance problem due to the close ties with animals. Zoonotic diseases increase even more as human being keeps dispersing and invading natural wild environments to raise cattle and farm, among other activities. The etiologic agent is the element that propitiates the origin and evolution of a disease. Many bacteria and viruses might be considered to be one of the most common etiological agents.

Populations in contact with goats, sheep, and cattle, use to have a positive result for antibodies against Coxiella burnetii. This bacteria is transmitted to humans orally and by inhalation. The microorganisms resist extreme conditions and are highly infectious. The inhalation of only one cell can produce an important infection in the host. It resists desiccation and any other environmental degradation. They can persist for several months and be transported by winds to farther places. This makes it even more difficult to determine the epidemiologic origin.

in what ways can overpopulation be beneficial to differential reproductive success?

Answers

Answer:

Differential reproduction is called the one that occurs as a result of the differences between the individuals that make up a society or sample, where it is those with comparative advantages who manage to reproduce, while those who do not have said advantages tend to die out. It is, in short, a practical application of Charles Darwin's theory of natural selection.

Thus, if there is an overpopulation of a certain species, a series of effects will occur (such as the scarcity of resources, the lack of living space, etc.) that will tend to gradually decrease the population to return to an ideal number of individuals. In this aspect, differential reproduction will be applied, being able to reproduce those that have comparative advantages over the rest, which will inevitably become extinct.

as a cell's size increases, what happens to the ratio of its surface area to its volume?


A:the ratio stays the same


B:the surface area increases as the volume increases



C:the surface area does not increase as fast as the volume increases



D:the ratio of surface area to volume does not matter

Answers

Answer:

Surface Area to Volume Ratios: Notice that as a cell increases in size, its surface area-to-volume ratio decreases. When there is insufficient surface area to support a cell's increasing volume, a cell will either divide or die.
