Explanation:
tumor suppressor of this type of gene leads to deregulated cellular proliferation, as in cancer. In a person born with two normal copies of a tumor suppressor gene, both copies must be inactivated by spontaneous point mutation, deletion, or failure of expression before tumor formation occurs. An inherited mutation in a tumor suppressor gene is the basis of most familial predispositions to cancer. In a person so predisposed, malignant cellular proliferation does not occur until the remaining intact copy of the gene is inactivated by deletion of part or all of its chromosome. Of many tumor suppressor genes thus far identified, the p53 gene on chromosome 17, which encodes a phosphoprotein that suppresses cell proliferation, appears to be the most important. Mutations of p53 have been found in the DNA of more than half of all human cancers studied. Li-Fraumeni syndrome, characterized by early-onset carcinomas and sarcomas, is an inherited (autosomal dominant) mutation in the p53 tumor suppressor gene. BRCA1 and BRCA2, involved in familial early-onset breast cancer as well as ovarian and other cancers in people of both sexes, are tumor suppressor genes.
Breast cancer is cancer that forms in the cells of the breasts.
Signs and symptoms of breast cancer may include:
A breast lump or thickening that feels different from the surrounding tissue
Change in the size, shape or appearance of a breast
Changes to the skin over the breast, such as dimpling
A newly inverted nipple
Peeling, scaling, crusting or flaking of the pigmented area of skin surrounding the nipple (areola) or breast skin
Redness or pitting of the skin over your breast, like the skin of an orange
Charcot-marine-tooth syndrome is a group of inherited disorders that cause nerve damage. This damage is mostly in the arms and legs (peripheral nerves). Charcot-Marie-Tooth disease is also called hereditary motor and sensory neuropathy.
Charcot-Marie-Tooth disease results in smaller, weaker muscles. You may also experience loss of sensation and muscle contractions, and difficulty walking. Foot deformities such as hammertoes and high arches also are common. Symptoms usually begin in the feet and legs, but they may eventually affect your hands and arms.
Symptoms of Charcot-Marie-Tooth disease typically appear in adolescence or early adulthood, but may also develop in midlife.
Signs and symptoms of Charcot-Marie-Tooth disease may include:
Weakness in your legs, ankles and feet
Loss of muscle bulk in your legs and feet
High foot arches
Curled toes (hammertoes)
Decreased ability to run
Difficulty lifting your foot at the ankle (footdrop)
Awkward or higher than normal step (gait)
Frequent tripping or falling
Decreased sensation or a loss of feeling in your legs and feet
As Charcot-Marie-Tooth disease progresses, symptoms may spread from the feet and legs to the hands and arms. The severity of symptoms can vary greatly from person to person, even among family members.
Charcot-Marie-Tooth disease is an inherited, genetic condition. It occurs when there are mutations in the genes that affect the nerves in your feet, legs, hands and arms.
Sometimes, these mutations damage the nerves. Other mutations damage the protective coating that surrounds the nerve (myelin sheath). Both cause weaker messages to travel between your limbs and brain.
Charcot-Marie-Tooth disease is hereditary, so you're at higher risk of developing the disorder if anyone in your immediate family has the disease.
Other causes of neuropathies, such as diabetes, may cause symptoms similar to Charcot-Marie-Tooth disease. These other conditions can also cause the symptoms of Charcot-Marie-Tooth disease to become worse. Medications such as the chemotherapy drugs vincristine (Marqibo), paclitaxel (Abraxane) and others can make symptoms worse. Be sure to let your doctor know about all of the medications you're taking.
Complications of Charcot-Marie-Tooth disease vary in severity from person to person. Foot abnormalities and difficulty walking are usually the most serious problems. Muscles may get weaker, and you may injure areas of the body that experience decreased sensation.
Sometimes the muscles in your feet may not receive your brain's signal to contract, so you're more likely to trip and fall. And your brain may not receive pain messages from your feet, so if you've rubbed a blister on your toe, for example, it may get infected without your realizing it.
You may also experience difficulty breathing, swallowing or speaking if the muscles that control these functions are affected by Charcot-Marie-Tooth disease.

Consider a population of 100 fox squirrels. The population is increasing exponentially, by a rate of 30% each year. If this rate continues, how many fox squirrels will there be in this population after two years?
Answer:
Future population = 169 squirrels
Explanation:
Given:
Current population = 100
Rate of growth = 30 % = 0.30
Time = 2 year
Find:
Future population
Computation:
Future population = 100(1+0.30)²
Future population = 100(1.30)²
Future population = 100(1.30)²
Future population = 169 squirrels
If a bee colony with 50,000 bees loses 30 percent of its bees during one winter, how many bees will survive that winter?

the ball is pushed so it begins to roll down the hill . it now has _______
A) kinetic energy
B) a rest position
C) more potential
D) no energy
Hi there!
[tex]\large\boxed{\text{A) Kinetic Energy}}[/tex]
When an object begins at rest but a force acts upon it to cause it to be in motion, energy transfer occurs.
In this instance, the ball was initially at rest, so it had potential energy. Once the ball begins is in motion, however, the potential energy is converted into Kinetic Energy.

3 reasons why bringing back extinct animals would help preserve the planet
Answer:
3 reasons why to bring back extinct animals would help preserve the earth is:
1.) Revived species could also assist conservation by acting as a “flagship species”.
2.) People may be excited to see a formerly extinct species, and are more willing to engage in conservation.
3.) At the same time, extinct species could also reinforce the preservation and protection of natural habitats.

A red Corvette is traveling down Broad St. At 45mph. The speeld limit is 25 mph. The car is captured on camera speeding, how many miles per hour was the car traveling over the speed limit?
Answer:
The answer is 20 mph
Explanation:
This question is more technical than it is of actual calculation. The car was travelling at a speed of 45 miles per hour when the actual speed limit that should be observed is 25 miles per hour. His excess speed can be calculated as
45 mph - 25 mph = 20 mph
Thus, the car was travelling at a speed of 20 mph more than the actual speed limit of the road which is 25 mph

Name two other subcellular structures that can be found in an animal cell.
1. ......
2. .......
Answer:
Any two other subcellular structures that can be found in an animal cell are:
nucleus.
mitochondria
The two other subcellular structures that can be found in an animal cell are nucleus and mitochondria.
An animal cell is a type of eukaryotic cell which lacks a cell wall and has a true, membrane-bound nucleus along with other cellular organelles which are present.Animal cells range in size from a few microscopic microns to a few millimetres.
Animal cells are eukaryotic cells with a membrane-bound nucleus. Furthermore, these cells exhibit the presence of DNA inside the nucleus. They also comprise other membrane-bound organelles and cellular structures that carry out specific functions necessary for a cell to function properly.
A nucleus is defined as a double-membraned eukaryotic cell organelle that contains the genetic material.It contains the cell’s hereditary information and controls the cell’s growth and reproduction.
The nucleus has been clearly explained as a membrane-bound structure that comprises the genetic material of a cell.
A mitochondrion is an organelle found in the cells of most eukaryotes, such as animals, plants and fungi. Mitochondria have a double membrane structure and use aerobic respiration to generate adenosine triphosphate (ATP), which is used throughout the cell as a source of chemical energy.
Thus, two other subcellular structures that can be found in an animal cell are nucleus and mitochondria.

Where does the energy come from that makes the movement of air and water possible?
Answer: Solar energy
Explanation:
The water and wind cycle is driven by the solar energy. The solar energy evaporates the water from the water bodies like oceans, rivers, lakes, and ponds and from other sources of water.
The earth's surface absorbs the heat radiations from the solar energy and the air above the earth's surface get hotter due to absorption of heat.
