The concentration of solutions is measured in a unit called moles (M). Now that you know this, use the picture to answer questions #1 - #5. The picture shows a red blood cell floating in a solution in a beaker. The picture also shows the concentrations of salt inside the red blood cell and the concentration of salt in the beaker.
Answers
Red blood cells (RBCs) would have a larger solute content outside of them than inside of them if they were detected in a concentrated salt solution.
Osmosis would cause the water to leak out of the cell, causing it to shrivel and stop functioning.
What occurs to red blood cells when they are exposed to a hypertonic solution?A red blood cell will swell up in a hypotonic solution and maybe rupture, but in a hypertonic solution it would shrink, making the cytoplasm thick and its contents concentrated, and may even perish.
Active transport involves the movement of chemicals from a low-concentration location to a high-concentration area in opposition to the concentration gradient. Being "active" means that this process uses energy (usually in the form of ATP).
Due to the diffusion mechanism, which asserts that water flows from a high concentration of water (RBC) to a low concentration of water when a cell is immersed in a concentrated solution (saline water).

How small are the cells that live in and on the human body
Answers
Answer:
The size of human cells varies from one to another, but they are all very small. Even the largest of all, the fertilized egg, is so small that it is not visible without the need for special instruments.
Explanation:
Some traits are part of an organism's physical appearance, such as a person's eye color, height or weight. Other sorts of traits are not easily seen and include blood types or resistance to diseases. Some traits are inherited through our genes, so tall and thin people tend to have tall and thin children. Other traits come from interactions between our genes and the environment, so a child might inherit the tendency to be tall, but if they are poorly nourished, they will still be short. The way our genes and environment interact to produce a trait can be complicated. For example, the chances of somebody dying of cancer or heart disease seems to depend on both their genes and their lifestyle.
Genes are made from a long molecule called DNA, which is copied and inherited across generations. DNA is made of simple units that line up in a particular order within this large molecule. The order of these units carries genetic information, similar to how the order of letters on a page carries information. The language used by DNA is called the genetic code, which lets organisms read the information in the genes. This information is the instructions for constructing and operating a living organism.
The information within a particular gene is not always exactly the same between one organism and another, so different copies of a gene do not always give exactly the same instructions. Each unique form of a single gene is called an allele. As an example, one allele for the gene for hair color could instruct the body to produce much pigment, producing black hair, while a different allele of the same gene might give garbled instructions that fail to produce any pigment, giving white hair. Mutations are random changes in genes and can create new alleles. Mutations can also produce new traits, such as when mutations to an allele for black hair produce a new allele for white hair. This appearance of new traits is important in evolution.

what is the the relationship between a geographical location distance from the equator and climates tempature?
Answers
Answer:
There is a relationship between latitude and temperature around the world, as temperatures are typically warmer approaching the Equator and cooler approaching the Poles. There are variations, though, as other factors such as elevation, ocean currents, and precipitation affect climate patterns.
Answer:
The distance from the equator affects the climate of a place. At the poles, energy from the sun reaches the Earth's surface at lower angles and passes through a thicker layer of atmosphere than at the equator. This means the climate is cooler further from the Equator.

The reaction ADP + P --> ATP is an example of an endergonic reaction because it needs free energy to continue (Option A).
What is an endergonic reaction?An endergonic reaction is one that needs to obtain energy from the surrounding media in order to continue. Conversely, an exergonic reaction can proceed by releasing an amount of energy that allows continuing the process.
Therefore, we can conclude that the condensation of adenosine diphosphate or ADP and monophosphate or P to form adenosine triphosphate or ATP reaction is endergonic that only happens if more energy is provided by the surrounding media (Option A).

2. Enzymes use light energy to speed up chemical reactions.
3. Enzymes lower the activation energy of a reaction.
4. Enzymes change shape during chemical reactions.
Answers
Enzymes speed up the chemical reactions (3) by lowering the activation energy of a reaction.
Enzymes are the biological catalysts that enhance the rate of chemical reactions inside the living organisms. These enzymes are very essential to make the body function normally. The various examples of enzymes present inside the human body are: pepsin, amylase, catalase, etc.
Activation energy is the minimum amount of energy required to begin a chemical reaction. More is the activation energy more is the time required to complete the chemical reaction. This is the reason why enzymes are required to speed up the chemical reactions.

Convection currents are the result of a physical-chemical process in which chemicals are heated and this decreases their density, causing their elevation. At the same time, the elements in the top sink because of lost temperature and increase in density, creating a cycle. According to the above, the correct answers are B Clouds and D. Storm Systems. Clouds are the result of a cycle of water, in which the water on the earth in a liquid state evaporates due to the caloric energy from the sun, changing to a gas state and go up until becoming droplets again in a process called condensation forming cloud. Once the cloud is very heavy and lost its temperature, it precipitates to the earth due to the force of gravity, and then the cycle starts again. Secondly, storm systems are a kind of cloud, those clouds develop vertically thanks to the convection process, in this, the same process occurs but the clouds have an internal air stream that makes that the clouds grow up vertically producing storms, those clouds are known as Cumulonimbus and Cumulus congestus. So, the correct answers are D. Clouds and B.Storm systems.

Client-centered veterinary hospitals allow for:
Answers
Veterinary practice today presents an interesting landscape. It is now extremely clear that veterinary medicine is a service business and that we must engage our clients in a way that promotes a level of trust, so that clients will be open and receptive to medical recommendations, offered to advance the wellbeing of their pet (or production animals).
The economic challenges of the past four years have circled the globe and presented new and additional business pressures for many veterinarians relative to the fiscally sound operation of their practices. Many veterinarians blame the economic downturn and slow recovery for the flat returns or declines in their business revenues during these interesting times. The Bayer Veterinary Care Usage study conducted in 2010 and 2011 lends credence to this view noting that 51% of practice report fewer visits and 42% of practice report reduced revenues. Several key elements were identified in this study including: the economic downturn, fragmentation of veterinary services, resistance by the feline sector (to seek veterinary services), use of the Internet to gain information, the perception that health care visits are unnecessary and the high (real or perceived) cost of healthcare. It's interesting to note that amongst the challenges enumerated, all but the economic downturn and fragmentation of service are issues that can be addressed through client education.
The veterinary profession across the United States and perhaps elsewhere, has not done a good job of educating our clients about the need for regular, thorough preventative health care for their animals, animals that they consider to be family members and in some cases, child surrogates. It is essential that veterinary health care teams engage in relationship centered, compliance driven care, designed to enhance the wellbeing and longevity of pets. That requires that we demonstrate (explain) the value of preventative health care to our clients so that their pets will live comfortably into their full genetic potential.
The truth is that there are many practices that are doing great medicine, harvesting great profits and enjoying the practice of medicine while others languish and even decline.
How can this be? I believe it all comes down to attitude. Attitude controls our thinking and our actions. By extension, attitude controls our commitment to a successful future, our focus, energy, and actions. My hope is to share with you, a series of ideas for you to consider implementing in your hospital so that you too, can have that "ideal" practice. There is however, a catch...you must be open to new ideas and willing to change what you do?
Most folks who are dissatisfied with the results of their practice efforts are inclined to continue focusing on the same goals, using the same methods, pursuing the same tasks and working harder than ever to achieve their desired end. The thinking is that "if I just work a little harder, this will all turn around". It's been said that doing the same thing over and over and expecting different results is the working definition of insanity.
This is paradigm paralysis in its most obvious form. It occurs when we allow our paradigm to become THE paradigm. As we become deeply vested in a given paradigm, our resistance to change increases. In fact, we are so vested in our current paradigm that we can't even envision a different paradigm. Folks stay locked on their known and comfortable but generally underwhelming operational track and as a result, their businesses languish.
The paradigm shift that must occur is that the appointment becomes a client-centered experience. Practices must shift from simply delivering a service or a product (many of which are available over the internet and large retail outlets) and deliver an experience. Health care teams must adopt an approach of under-promising and over-delivering on opportunities for "best care" in the most relational and bonded way possible.
