In this population lambda changes slightly over time, starting at 1.41 before dropping down to 1.34 and rising again to 1.43 where this value becomes regulated. This indicates that the population growth rate drops before becoming regulated. This compares to the growth of the hypothetical population described in Figure 10.8 as 10.8.B indicates that the population growth rate drops from an initial point before rising again and then becoming regulated. While in this figure there is more fluctuation in the growth rate overall, and there exists two larger drops in growth rate before regulation, the pattern of a growth drop-off before growth regulation is still reflected in both examples. I predict the population will continue to grow steadily as the lambda also known as the growth rate remains constant. The population will continue to grow in future years with the age-specific survival rates not changing. However, such growth cannot extend on forever, at some point the population will reach its carrying capacity in which resources are limited to a point where further population cannot be sustainably maintained. Population growth around this time will drop to the point where the population is maintained steadily as resource constraints will reel in any spikes in population size and/or growth. 

A survivorship curve is a graphical representation of data that is compiled from the life table of a specific population of organisms. There are three different types of survivorship curves. A type 1 survivorship curve describes a species in which newborns and juvenilves will have a high survival rate.Death rates for this curve do not be to increase significantly until old age has been reached. Examples of type 1 survivorship can be seen in the dall mountain sheep. A type 2 surviorship curve deals with a species in which individuals have an approixmately constant chance of surviving from one age to the next throughout their lives. Species that have type 2 survivorship include organisms such as some birds, fish, and mud turtles. Type 3 surviorship curve details a species in which individuals die at a very high rate when they are young, however when they reach adulthood they will most likely survive later in life. This type of survivorship is the most commonly seen type of survivorship in nature and is typical of species that produce large numbers of offspring.

Ketosis is defined as a state where an individual’s body is producing ketones as a result of a deficiency in carbohydrates. In ketosis, the body starts to break down fat as its energy source, instead of carbohydrates. This is usually accompanied by a drop in blood sugar. Although this seems like a harmful idea, a new dieting trend in the past couple of years has been the ketogenic diet. This diet includes a meal plan revolving around high fat, low carb and high protein. The idea of this diet is to starve the body from carbohydrates so that it is forced to burn fats as a source of energy. Although extreme, this diet has surprisingly shown many benefits. The ketogenic diet can aid in extreme weight loss and is recommended for patients with many chronic conditions such as diabetes and poly cystic ovary syndrome. This diet was first discovered as a meal plan that helped patients with epilepsy. Extensive research has proved that the ketogenic diet reduced seizure in patients with this condition. However, there are many unpleasant side effects to the ketogenic diet, including stomach pain, fatigue, fogginess, nausea, and trouble sleeping. There is little known about the long term benefits of this diet. Many doctors have mixed feelings about this diet, and there is much more research to be done about this diet. 

When people hear that all dogs are going to die except for one mother and her litter of one species, there is a gut-wrenching sadness felt by millions. Dogs have evolved with mankind to be what they are today, whether they be guides, hunters or companions. When it comes to life and death situations it is easy to rash decisions based on former experience with a certain breed, but when it comes to life and death and the good of humanity, there needs to be a more evaluation. Therefore, the Labrador Retriever must be saved, for it is not only one of the most beloved breeds for families, it is also the most versatile.

 Everyone knows that a lab makes for a good pet, they are gentle giants and great for families. Clearly one of the factors that goes into choosing a breed to survive is their affability towards people and families because this is what people have come to expect from dogs. They are lovable and friendly, with beautiful coats and a matching temperament. They are loyal and dependable and easy to trains. All of these are great qualities that would be desired of the last dog breed on earth.

Beyond that, Labradors are also capable of serving humans in other ways. They are capable of being service and guide dogs, for the disabled and blind, bomb dogs, for detecting threats, and search dogs for helping track and find missing people. People have developed a world where we depend on our four-legged friends to provide services beyond stalwart companion. In a world without many of the diverse breeds that serve in these roles, we must choose one that shows versatility. Labs show this versatility and it is their patience and devotedness that allows them to excel in these roles. They are a superior breed and it is the duty of those chosen to inoculate a given mother to forgo any lesser picks rooted in passion and choose the breed that will be the best for the entirety of the human race.

Due to a new retrovirus that is killing domestic dogs at rapid speeds, only one vaccine can be made to save one breed. Dogs are often referred to as “man’s best friend” and a breed that represents this should be saved. The Labrador Retriever, one of the most popular and beloved dog breeds, makes the most sense to save for many reasons.

Unfortunately, we must choose only one dog breed to save before all dog breeds go extinct for good. All dogs are special and can have a nice companionship with their owners, but Labrador Retrievers are some of the best well-rounded dogs in the world. They are beautiful, not hard to please, and easy to train.

The Labrador Retriever does well in a variety of environments and  is known for being an overall good dog. They have a loyal, loveable, and happy personality that any family would be happy to have in their home. They make for good companions and are happiest when they are with you. It is not difficult to please Labrador Retrievers and it is easy to form a meaningful bond with this beautiful breed.

You may think that cells just live, grow, and survive on their own, but cells actually need signals that tell them to survive. The survival signal pathway plays an important role for controlling cell survival and programmed cell death. If there are certain changes or mutations in this pathway, it can lead to uncontrolled cell death or survival. The key players in this pathway are RTK, PI 3-kinase, PIP3, Akt, Bad, and Bcl2. When the survival signal binds, it causes cross phosphorylation of RTK to occur. The added phosphates act as a binding site for PI 3 kinase. When PI 3 kinase binds to RTK, it is activated and phosphorylates PIP2, creating PIP3. Once phosphorylated, PIP3 is a binding site for Akt as well as protein kinase 1. Protein kinase 1 and 2 phosphorylate Akt, which leads it to dissociate from PIP3. As a result, Akt can phosphorylate Bad, preventing it from causing programmed cell death. Inactive bad allows Bcl2 to inhibit programed cell death and send the survival signal.
