Answer:
Mangroves
Explanation:
Ruffled trees that grow on the north Atlantic coast of Florida. Mangroves are rapidly adapting to climate change. When an area becomes hospitable, its seed, which can float away for a long time, soon begins to germinate and take root in it. They represent a unique ecosystem and usually grow in shallows near the coast.
What do variations create?
Variations in species help them to adapt themselves to that particular environment and give them a chance of survival. For example, thermophilic bacteria are variants that are resistant to extreme temperature. They have a chance of survival in high temperate zones while others die.

14. To cause cancer, proto-oncogenes require 2 allele(s) to be mutated and therefore are considered recessive. The mutation results in a gain of function.
15. To cause cancer, tumor suppressor genes require 2 allele(s) to be mutated and therefore are recessive. The mutation results in a loss of function.

Answer:
Family snapshot - chimps and humans are very closely related. Similarities are often easy to see when one looks at two organisms that evolved from a common ancestor, and until recently, looking at physical features and behavior was the only way to determine how closely related two organisms are.

Why does the body produce more urine on a cold day rather than a hot day if the same amount of
water is consumed?
Explanation:
During summer when the surrounding temperature is high, we lose water in the form of sweat, direct evaporation considerably. Hence kidneys retain water for maintaining fluidity of the blood and less urine is formed.
But during winter, the surrounding temperature will be very low. There will not be any sweating, no evaporation losses. Moreover to keep the body temperature constant, the blood capillaries in the skin get constricted and the blood pressure is increased. The result is that our body gets warmed up. In order to maintain the blood pressure normal, the excess water along with the wastes is excreted mostly in the form of urine. This is the reason for more urine out put and frequent urination under very cool conditions and in winter.
What is a bacteria that is beneficial to humans and what does it do?
How will you react if I tell you that your body consists of 1 to 2.6 kg of bacteria? Shocked? Well, I can imagine your surprised face. Most people believe that bacteria are dangerous and are responsible for diseases and infections but this isn’t true. In fact the truth is, most of the bacteria are helpful in the functioning of a living body and are also capable of performing many other useful functions. These beneficial bacteria are present in huge numbers inside as well as outside our body. Well let’s check out various types of beneficial bacteria which not only help in proper functioning of our body but also contribute in many other functions in and outside the body. Some of the examples of helpful bacteria are Bifidobacterium, Rhizobium and E.coli.
Beneficial Bacteria – to Humans
Human body has millions of bacteria which participate in different functions of the body. As you know the amount of bacteria present in the body varies from 1 to 2.6 kg, this volume contains a huge number of bacteria. These bacteria can be present in all parts of the body but mostly they are found in the intestine where they help in the process of digestion. They also play a very important role in preventing bacterial infections in genital parts, like yeast infections. Some beneficial bacteria to humans are helpful in maintaining the pH of the body. Some are even involved in protecting the skin from many infections.
They are also helpful in the production of vitamin K and have an important role to play in the functioning of immune system. One of the most common bacteria which are helpful for humans is Escherichia coli. This bacteria is associated with the process of digestion. It is present in the large intestine where the maximum digestion takes place. These bacteria release enzymes which help in the process of digestion and synthesis of various vitamins and nutrients. Beneficial bacteria are also very helpful for the pregnant women. They reduce the chances of postpartum complications and also protects the baby from fungal infections.
Answer:
Probiotics are live bacteria that are good for us, that balance our good and bad intestinal bacteria, and that aid in digestion of food and help with digestive problems, such as diarrhea and bellyache. Bacteria that are examples of probiotics are Lactobacilli and Bifidobacterium.
Glycogen synthetase kinase 3 beta is a protein kinase that has been implicated in many types of cancer. Depending on the cell type, the gene for glycogen synthetase kinase 3 beta (GSK38) can act ether as an oncogene or as a tumor suppressor. Which of the following best predicts how GSK 98 mutations can lead to the development of cancer? A Cells with inactive GSK 38 fail to trigger apoptosis. B Cells with inactive GSK 38 fail to proceed past the G2/M checkpoint. с Cells with overactive GSK 98 are more likely to repair DNA damage. Cells with overactive GSK 38 have longer cell cycles.
Answer:
A Cells with inactive GSK 38 fail to trigger apoptosis
Explanation:
Apoptosis is defined as the process of programmed death cell. Tumor cells are capable of evading apoptosis, thereby leading to uncontrolled cell proliferation. Glycogen synthase kinase 3 (GSK-3) is a protein kinase that phosphorylates serine and threonine amino acid residues on different substrates, thus activating different signaling pathways and having different biological functions. The GSK-3-mediated phosphorylation on different substrates may lead to the activation or inactivation of apoptosis depending on the cell type. Thus, GSK-3 has a dual activity and functions as a tumor suppressor and oncoprotein.
