2. in cardiac muscle, acetylcholine binds to muscarinic acetylcholine receptors (machrs), which are g-protein coupled receptors, which elicit a signal transduction pathway that induces cardiac muscle to relax. outline how g-protein coupled receptors induce signal transduction pathways including relevant secondary messengers.

3. interpret dr. peterson’s statement that active transport is essential for facilitated diffusion of na+ ions to occur in muscle cells. how are na+/k+ pumps involved in this process? sketch a na+/k+ pump indicating conformational changes and energy usage steps and identify ions that are moved during the cyclic process.

4. generally, after neurotransmitters are released in the neuromuscular junction, many of the neurotransmitters or some of their components are recycled by a reuptake mechanism inherent in the pre-synaptic neuron. considering that the reuptake mechanism is often a sodium-dependent process that utilizes membrane potential, what type of membrane transport might you expect to be in play here?

Answers

Answer 1

Uniporter allows the movement of a subtance in one direction, symporter two molecules in the same sense and antiporter two in opposite sense. Nicotinic acetylcholine receptors are linked to symporters to allow the movement of neurotransmitters. G protein function is coupled to second messengers such as cyclic AMP, active transport allows the movement of substance again a concentration gradient and reuptake mechanism involves symporter transport.

What are uniporter, symporter, and antiporter?

The terms uniporter, symporter, and antiporter make reference to different types of channel proteins located in the cell membrane which allows the movement of molecules through this selectively permeable barrier.

Moreover, nicotinic acetylcholine receptors are receptors that bind to certain neurotransmitter chemical messengers such as acetylcholine in order to allow the movement of ions through the membrane.

Therefore, with this data, we can see that uniporter, symporter, and antiporter are different classes of channel proteins in regard to the movement of molecules in and out of a selectively permeable barrier (i.e. the cell membrane).

Answers

The scientific law of one organism feeding off other where energy is transferred from one form to another is known as the law of conservation of energy.

How the sun is the primary source of energy for ecosystems?

Energy from the highest energy source that is sun is absorbed by plants to convert it into food (i.e a form of energy). plants are the only ones that can convert sunlight into another form of energy directly.

The animals and organisms that feed off of the plants take some part of this energy for their life cycles and then the animals that feed off of these animals again take some part of this energy and carry on with their life cycle, this is how energy from sun (highest source) is transferred to different organisms by Just changing form.

A: Suited for their environment

Explanation:

You can automatically eliminate B and C, since they both say that animals with adaptations that won't work with their environment would have a higher survival rate. This doesn't make sense; adaptations that wouldn't suit an environment would actually lower the population's chances of reproduction and survival.
That leads us to A and D. However, A would be the correct answer. Organisms with adaptations that suited their environment would help them (since it would make the organism more compatible with their environment), rather than having no change at all.

The Coriolis Effect shows us that when moving from the equator towards the poles, the air is moving slower than the ground below it. So, the correct option is A.

What is Coriolis Effect?

The French mathematician & physicist Gaspard-Gustave de Coriolis is honoured with the name "Coriolis Effect." It has an impact on everything from ocean currents to weather patterns to aviation transport. Despite how significant the Coriolis Effect is, few people are aware of it and even fewer actually comprehend it.

Circulating air gets deflected to the right throughout the Northern Hemisphere as well as to the left inside the Southern Hemisphere as a result of the Earth's axis of rotation. The Coriolis effect is the name given to this deflection. The Coriolis Effect demonstrates that the air moves more slowly than the ground underneath it as it travels from the equator to the poles.

Therefore, the correct option is A.

A man with red-green colorblindness has one brother who has normal version. From which parent did the man inherit colorblindness? Explain how you know using a Punnett square to © 2014 Vanessa Jason (“Biology Roots”
back up your answer.

Answers

Since the colorblindness is located on the X chromosome, the man must have inherited his colorblindness from his mother.

X-linked traits

Women are XX while men are XY.

Also, the X chromosome in XY always comes from the mother.

Since the man is affected for colorblindness but his brother is not, it means that only one X chromosome of the mother is affected while the father can be affected or otherwise.

Assuming the father is free from colorblindness and the allele is represented by c:

          [tex]X^cX[/tex]    x    [tex]XY[/tex]

      [tex]X^cX[/tex]    [tex]X^cY[/tex]    [tex]XX[/tex]    [tex]XY[/tex]

The obelisk from the temple of Luxor in Egypt (left) and the Egyptian obelisk called Cleopatra's Needle in New York (right).In New York temperature is low,considerable cloudiness with occasional rain showers.

What are factors that can speed up the process of weathering?

The amount of rainfall and the temperature can influence how quickly rocks weather. The pace of chemical weathering is accelerated by high temperatures and heavier rainfall. 2. Compared to comparable rocks living in cold, dry climates, rocks in tropical regions exposed to heavy rainfall and high temperatures weather far more quickly.

Chemical weathering is accelerated by moisture. Hot, humid regions are the ones that weather the fastest. In hot, dry areas, it happens extremely gradually. Ice wedging is not possible without temperature variations.

Significant influences in weathering include physical forces like temperature and humidity, chemical forces like oxidation and carbonation, and biological forces like animal and human activity-related burrowing.
