How are muscles the contractile specialists of the body?

Answers

Answer 1
Muscle cells are uniquely adapted to contractile function due to three main things. FIrst, they have a large capacity for storage of readily available glycogen to use for work. Second, they contain the actin and myosin cross-bridge cycling structure to perform a contraction of a muscle fiber. Finally, each fiber has central nervous innervation to control contraction and relaxation of the muscle fibers.

Identify the relationships between the zooxanthellae and the hard coral, the remora and the manta ray, the tiger shark and the green sea turtle, and the dolphin and the school of trevallies and state why you chose that relationship. The relationships will be predation, competition, commensalism, or mutualism.

Answers

Zooxanthellae and the hard coral-Zooxanthellae are the symbiotic algae that live within the hard or stony corals. The symbiotic relation is based on the coral's inability to generate sufficient amounts of food and the algae’s ability for photosynthesis and converting chemical elements into energy. - mutualism 

The remora and the manta ray-The benefits to the remoras and remora for living in such close association with their larger hosts are clear, but there is a debate about whether the manta rays receive a significant return in benefits from these relationships. - mutualism 

The tiger shark and the green sea turtle - the turtle is eaten by the shark-predation 

The dolphin and the school of trevallies-To feed, dolphins use a fast, surprise attack, and, unlike the hunting packs of trevallies, dolphins can successfully hunt alone. - predation

Most patients with schizophrenia demonstrate a lower level of frontal lobe activity than healthy control participants. why would this difference be significant?

Answers

The frontal lobe has, as some of its functions, the capability to project possible consequences as a result of current actions leading to the choice between worse and better actions, as well as the ability to give importance or suppress socially unacceptable responses. It is also important when it comes to integrating memories associated with emotions, where the frontal lobe use them to fit socially acceptable norms.

Answers

I believe the answer is true..

Answer: True

The nuclear fuel cycle involves the generation of nuclear energy in a nuclear reactor by utilizing various sources of radiations in a thermal power station. The nuclear fuel is sensitive to impact or friction. If it receives impact or friction, an explosion can occur. Therefore, these fuels should be transported in an appropriate container and should be dump either on shallow land or in water so that dumping does not result in air blast effects or explosion. Hence, final stage of the nuclear fuel cycle involves the spent fuel must be transported, processed, and disposed of properly.

How do doctors detect abnormalities in patients with the help of an EKG?

Answers

The EKG will show up very unnormal and will change the pattern.

The right answer is by determining changes in the heartbeat

Three questions are unavoidable when interpreting an ECG:

• What is the heart rate?

A normal frequency is between 50 to 100 / minute. Below 50 / min, we are talking about bradycardia, above 100 / min, we are talking about tachycardia.

• Is the heart rhythm regular or irregular (arrhythmia)?

On a normal ECG, the space between 2 Q-R-S is always the same regardless of the time of recording (in green in the following diagram). This question is fundamental to detect arrhythmias.

• Is the rhythm sinus (or normal)?

Each P-wave must be followed by a Q-R-S segment. This question will help identify conduction disorders between the atria and the ventricles.

unobservable

stabilizing

Answers

The effect of human disturbance on animal population is density-independent.
Which is answer C.
Hope this helps!

Answer: density-independent

Explanation:

A limiting factor is the one which is responsible for the decrease in the growth , abundance and distribution of the population of a species in an ecosystem. It can be a living agent or a non-living agent. A density independent factor is the one which limits the growth of the population and it does not depend upon the density of the species population. A density dependent factor is the one which limits the growth and abundance of the population of the species on the basis of the density. More the density more profound will be the impact for example a disease is likely to be spread among the members of the population of a species.

The effect of human disturbance on animal is an example of density independent limiting factor as the human beings while using animal products or disturbing their habitats does not consider about the consequence of the affect. But some animals recover this loss by reproducing more progenies but others which cannot may extinct.

Compare and contrast diffusion and osmosis and predict the direction of water a solute movement across a selectively permeable membrane.

Answers

In diffusion, the molecule is moving from the container with higher concentration into the lower concentration, resulting in a similar concentration between both containers in the end.
But in osmosis, the molecule can't move. The molecule can attract water, so the container with higher concentration will attract more water. This will cause the water to move, not the molecule. The water will move from the container with lower concentration into the higher concentration. The result after the osmosis should be both containers have similar concentration, just like diffusion.

Similarities

Diffusion and osmosis are both examples of passive transport.

They transport substances down a concentration gradient.

Difference

Diffusion is the movement of solute particles down a concentration gradient. Osmosis is the movement of water molecules down a concentration gradient.

FURTHER EXPLANATIONActive and Passive Transport

Passive transport is the movement of particles through a membrane which requires no extra energy. It happens spontaneously because there is an imbalance in the amount of solutes  or difference in concentration inside and outside the membrane. In order to reach equilibrium or a state where the amount of solute or concentration on both sides is the same, some substances have to cross the membrane.

When substances move from a region of high concentration to low concentration, it is said that the substances are moving down a concentration gradient. This process is spontaneous meaning it does not require energy to occur. The opposite is true for active transport which requires additional energy for it to happen.

Movement of Substances

In diffusion, solutes move from a concentrated area to a less concentrated area.

In osmosis, the water molecules move from an area with more water molecules (lower concentration of solutes) to the area with less water molecules (higher concentration of solutes).

Answers

Producers are organisms that have the ability to use photosynthesis (plants) or other mechanisms (such as chemosynthesis in some extremophiles) to transform light, water, and carbon dioxide into organic matter and chemicals that are high in energy.

A food web is a chain of consumption in which producers are eaten by primary consumers (herbivores), who are then eaten by secondary consumers (carnivores), and so on.

The base level represents the producers in ecological pyramids (such as energy pyramids or biomass pyramids).

Therefore, Trophic levels, the energy or biomass declines, indicating both the transmission of energy and the fact that energy is lost at each level of the trophic pyramid.
