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 growth rate of this plant is about 30 feet per day, which is why it can cover large areas in a rela-tivelly short time period. This vine covers the native plants and trees covering the sun and air, which smothers and suffocates them. Since it is an invasive species, for example in the US, it does not have natural predators and outcompetes the native species for resources. As it competes with the native species, it disrupts the food chain because it threatens the plants that animals use for food and shelter and its roots modify the amount of water and nutrients that are in the soil.

This plant releases the chemicals isoprene and nitric oxide that when combined with the nitrogen of ozone can cause health troubles for humans.

During mitosis, daughter cells generate half as many chromosomes. Anaphase I sees the complete attachment of the spindle fibers. The homologous chromosomes travel to opposing ends of the cell by pulling apart.

What is mitosis?The physical process that ultimately divides the parent cell into two identical daughter cells is known as cytokinesis. The cell membrane constricts at the cell equator during cytokinesis, creating the cleavage furrow, which is a cleft.Mitosis divides a parent cell into two identical daughter cells, each of which has the same amount of chromosomes. Meiosis, on the other hand, creates four distinct daughter cells, each of which has half as many chromosomes as the parent cell.When a parent cell divides to create two identical daughter cells, the process of nuclear division known as mitosis takes place in eukaryotic cells.Daughter cells that are genetically identical to their parent cells are created during mitosis. The cell divides its copied chromosomes equally to ensure that each daughter cell has a full set before copying, or "replicating," its chromosomes.

Explanation:

Genetics is the study of genes and tries to explain what they are and how they work. Genes are how living organisms inherit features or traits from their ancestors; for example, children usually look like their parents because they have inherited their parents' genes. Genetics tries to identify which traits are inherited and to explain how these traits are passed from generation to generation.

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.

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.

Time passing is life passing and the measurement of time is the measurement of life itself. How important then that our chronometers, or time measures, be accurate and faithful! It is said that a slight error in a general's watch caused the overthrow of Napoleon at Waterloo and thus changed the history of the world. Because of its great importance the measurement of time has always been a subject of deep human interest and the story of the clock begins with the history of primeval man.The larger periods of time are measured by the motion of the heavenly bodies. The year and the four seasons are marked off by the motion of the earth in its long journey around the sun; the months and the weeks are told by the changing moon; sunrise and sunset announce the coming and the going of day. The year and the seasons and the day were measured for primeval man by the great clock in the heavens, but how were smaller periods of time to be measured? How was the passing of fractional parts of a day, an hour or a minute or a second to be noted? An egg was to be boiled; how could the cook tell when it had been in the water long enough? A man out hunting wished to get back to his family before dark: how was he to tell when it was time to start homeward?The sun-dial can hardly be called an invention; it is rather an observation. There were, however, inventions for measuring time in the earliest period of man's history. Among the oldest of these was the fire-clock, which measured time by the burning away of a stick or a candle. The Pacific islanders still use a clock of this kind. "On the midrib of the long palm-leaf they skewer a number of the oily nuts of the candle-nut-tree and light the upper one." As the nuts burn off, one after another, they mark the passage of equal portions of time. Here is a clock that can be used at night as well as in the daytime, in the house as well as out of doors. Mr. Walter Hough tells us that Chinese messengers who have but a short period to sleep place a lighted piece of joss-stick between their toes when they go to bed. The burning stick serves both as a timepiece and as an alarm-clock.What is the central idea of the last paragraph? Burning things is a great way to tell time.
