Why is it possible to do the following party tricks without cheating?
A. Stand with back and heels touching a wall and bend forward from the hips to touch the floor. Return to the upright position without flling or moving the root.
B. Stand facing the edge of an open door with nose and abdomen touching the edge, the feetstraddling the door, and the hands to the sides. Attempt to rise up on the toes.Observe what body motions occur to keep the center of gravity within the base of support whenthese activities are performed without the impediments.
Answer:
When the body is supported by a wall then it can move in a position counter gravity. The gravity tries to pull the body down and the body responds to it with a slight delay because of wall support.
Explanation:
The body is lifted in upright position with the help of feet. The body rises but after few minutes the gravitational force creates pressure on the body and the body comes down to a natural state. Similarly if the open door is used to perform counter gravity activities then the body will stay for a lesser period in a state because of opened door instead of firm wall support.

Explanation:
the process of living organisms staying the same
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.
Metabolism is the sum of all the chemical reactions carried out in an organism. heredity is called a gene.

Explanation:
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
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.

c. enzymes involved with the degradation of interneuron signals enzymes involved with the degradation of interneuron signals.
d. neurotransmitters that excite or inhibit a neural signal across a synapse
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.

Answer:
A. A star’s final stages of life depend on its mass.
B. Stars die when they run out of fuel.
Explanation:
A star's life cycle is determined by its mass. ... Over time, the hydrogen gas in the nebula is pulled together by gravity and it begins to spin. ... It is now a main sequence star and will remain in this stage, shining for millions to ... When the hydrogen supply in the core begins to run out, and the star is no longer supported.
in what ways can overpopulation be beneficial to differential reproductive success?
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.
Plzzz help with the one with the membrane picture
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.
How do humans influence certain traits of organisms through various techniques?
Answer:
In artificial selection, humans have the capacity to influence certain characteristics of organisms by selective breeding. One can choose desired parental traits determined by genes, which are then passed on to offspring.

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:_______
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.
