Answer:
Cancer cells grow and divide at an abnormally rapid rate, are poorly differentiated, and have abnormal membranes, cytoskeletal proteins, and morphology. The abnormality in cells can be progressive with a slow transition from normal cells to benign tumors to malignant tumors.
Essentially, cancer is a disease of mitosis. As such, it occurs when normal cells are transformed into cancerous cells and proliferate uncontrollably. Cancer cells, therefore, are normal cells whose genes (several genes) have been damaged/mutated which in turn cause the cell as a whole to respond differently to signals that control the lifespan of a normal cell.
Because they do not respond to signals/instructions that control the development and death of normal cells, cancer cells continue to grow and proliferate and even invade other parts of the body. In the process, some of the cancer cells end up forming tumors not only at the first region to be affected (lungs etc) but also result in secondary malignant growths away from the primary site known as metastasis....
Some of the main characteristics of cancer cells that differentiate them from other normal cells include:
-Abnormally shaped and significantly vary in size
-Incapable of self-repair
-Do not go through normal apoptosis
-Do not perform normal cell functions (as is the case with specialized cells)

Three out of 7 students at the dance were boys if 140 students attended the dance how many were girls enter number of girls here ___
Answer:
80
Explanation:
We know that 3/7 people are boys. So, we know that 7/7-3/7, or 4/7 are girls.
We can find the total number of girls by multiplying that by 140.
[tex]\frac{4}{7}[/tex]×140 is the same as [tex]\frac{4}{1}[/tex]×20. Multiply 4 by 20, and we get 80!
What best describes the relationship between starch and glucose? A. Starch and glucose are reactants that combine to form proteins. B. Starch is a monomer that is used to make glucose. C. Starch is a polymer made of glucose monomers. D. Starch and glucose are reactants that combine to form nucleic acids.
Answer:
The correct option is C
Explanation:
Polymers are large molecules that are made up of single monomeric units called monomers. Examples of polymers and there corresponding monomers are
Protein (Polymer) ⇔ Amino acids (monomers)
Starch (polymer) ⇔ glucose (monomers)
polythene (polymer) ⇔ ethene (monomers)
Deoxyribonucleic acid (polymer) ⇔ nucleotide (monomers)
The glucose monomers are linked together in a starch molecule by glycosidic bonds.

If the manager or worker focuses on the defect prevention to a product, in which quality does he/she performed? *
Answer:
It enhances working efficiency of the product.
Explanation:
If the worker focuses on the defect prevention to a product, it enhances the working efficiency of the product because in the product there is no defect present which is responsible for better working of the product for a long period of time. So that's why the manager or worker of the company focuses on the quality of the product instead of its quantity.
Ensuring that products made and services rendered by a firm is free of defect and glitch is shouldered by the quality control team. Hence, such manager functions in the control aspect of quality.
The quality control team to a group of employees who checkmates the production and manufacturing process in other to ensure that the required rules and guidelines needed to deliver a flawless product or required service is followed.
Therefore, employees or managers who are in charge of preventing defect in goods and service are the quality control team.

1. How do glucose levels change when you exercise after meals versus when you don’t exercise?
2. What happens to the rate (speed) of respiration when we exercise?
3. Why would your cells need more glucose when you exercise?
Answer:
I think:
1. Exercising release reserve suger that is stored in you muscles.
2. When you exercise you start to work your body harder and you use more oxygen and produce mor carbon dioxide so for ur bpdy to cope with this to starts to increase your breathing.
3. your body need more glucose because of your body's exaggerated release of glucose-raising hormones such as adrenaline and glucagon.
Explanation:
I hope this helps.. but I could be wrong on some..
Intro:
Hello!!! Princess Sakura here ^^
Explanation:
1.) Exercising reduces blood glucose concentrations, so when you don't exercise it'll increase.
2.) When you exercise your muscles work harder and then your body will start to need more oxygen and produces more carbon dioxide.
3.) As you exercise, the insulin sensitivity increases, so your muscle cells are able to take up glucose during and after activity.

Power plants were built in the Imperial Valley as a means to harness power from geothermal resources. However, the construction of these power plants has led to the loss of habitat for burrowing owls. How can engineers and scientists solve the problem of habitat loss for burrowing owls and other wildlife?
Some of the ways Engineers and scientist can solve the problem of habitat loss are :
Planting more trees for animals and birds that live on treesCreation of Bird sanctuaries around the power plantsTo compensate for the loss of habitat faced by the birds and animals that were original inhabitants of the imperial valley just like the burrowing owls, scientists and engineers can create artificial bird sanctuaries just around the power plant to encourage the burrowing owls to resettle given that it will look like a familiar habitat to them.
Planting more trees in areas with an average amount of trees will also encourage the resettlement of animals and birds that live on trees because of the abundance of trees.
Hence we can conclude that Some of the ways Engineers and scientist can solve the problem of habitat loss are : Planting more trees for animals and birds that live on trees, Creation of Bird sanctuaries around the power plants.

BRAINLIEST: A satellite was in two separate crashes. In both crashes, the satellite had the same mass. Engineers want to know about the speed and direction of the satellite after the crashes. Why would the crash affect the motion of the satellite, and which crash caused a greater change in motion for the satellite?
Answer:
Crashing into the asteroid would cause the satellite to slow down, stop, or reverse direction, because it is a force in the opposite direction to the satellite's motion. Whichever crash was a stronger force would cause it to change motion more. It takes a stronger force to change the velocity of a more massive object.
Explanation:
Big change occur in the motion of the satellite when it is hit by a big and heavy object.
The crash greatly affected the motion of the satellite because the other object comes to the satellite in opposite direction which slower down the speed and sometimes also reverse the motion of the satellite.
That crash will bring great change in the motion of the satellite which is hit by a big and heavy object whereas if the object is small than it only slow down the speed of the satellite so we can conclude that the interaction with greater object will greatly affected the motion of the satellite.

which phrase best describes the difference between these two liquids
A. patterned particle arrangement versus disorganized particle arrangement
B. fixed volume versus changing volume
C. fixed shape versus changing shape
D. high surface tension versus low surface tension
Answer:
D. High surface tension versus low surface tension.
Explanation:
The metallic liquid has a rounder form rather than the brown liquid which lays flat on the surface.
The phrase that best describes the difference between these two liquids is ; ( D ) High surface tension versus low surface tension
The metallic liquid will easily form rounder drops due to its higher surface tension while the brown liquid will have to lay flat due to its lower surface tension.
Metallic liquids are liquids that have very high surface tension than other types of liquids. and readily forms round drops when spilled on a surface. An example of a metallic liquid is Mercury
Hence we can conclude that The phrase that best describes the difference between these two liquids is ; High surface tension versus low surface tension.
