Explain how cancer cells grow.
Answer:
Gene mutations in cancer cells interfere with the normal activity within a cell.This can cause it to grow out of control and/or not die when it should. Cancerous cells can continue to grow because they behave differently than normal cells do. Cancer cells differ from regular cells in many ways,one of their more apparent traits is that they divide quickly with no control over them.The amino acid glutamine is one of the many key factors to helping the growth of cancer cells. Like all cells, cancer cells need nutrients to grow,sugar is one important fuel for it's development, but is far from the only factor.

Nutrients Nutrients are substances in food that supply the body with energy and raw materials needed for growth, repair, and mainteNnce. The nutrients that the body needs are water, carbohydrates, fats, proteins, vitamins, and minerals.
- Many of the body's processes take place in water. Water makes up a large part of blood and other body fluids.
- Simple and complex carbohydrates are the body's main source of energy. Complex carbohydrates, such as starches, must be broken down into simple sugars to be used for energy.
- Fats are formed from fatty acids and glycerol. Fats help the body absorb fat-soluble vitamins and are a part of cell membranes, nerve cells, and certain hormones.
- Proteins supply raw materials for growth and repair of structures such as skin and muscle. Many enzymes and hormones are proteins.
- Vitamins are organic molecules that the body needs in very small amounts. They are needed to help the body perform chemical reactions.
- Minerals are inorganic nutrients the body needs in small amounts. Examples of minerals include calcium and iron.

What is Anabolic hormone ?Anabolic hormone has the one that has been involved in the formation of some specific substance just inside the body. Thus it can include repair of the damaged tissues as well as the growth of the muscles as well. There are the examples of the anabolic hormones which are insulin, growth hormones, testosterone, etc.
Insulin has been considered as the sugar regulatory hormone which is made up of the polypeptide chains. It has been called an anabolic hormone because it will promotes the uptake of the glucose by the cells in order to reduce the blood glucose levels. This promotes the formation of the glucagon which is a stored form of energy that can be result in increase muscle mass.
Therefore, The genotype of a true breeding tall plant in mendel's cross is TT. Thus, option B is correct.

A. favor the forward reaction.
B. favor the reverse reaction.
C. favor both the forward and reverse reactions.
D. have no effect on the equilibrium.
If an exothermic reaction has reached equilibrium, then increasing the temperature will favor the reverse reaction. So, the correct option is B.
What do you mean by Exothermic reaction?Exothermic reactions are those reactions in which the energy or heat is liberated apart from the product.
Increasing the temperature of exothermic reactions causes a decline in the concentration of products while enhancing the concentration of reactants.
Therefore, if an exothermic reaction has reached equilibrium, then increasing the temperature will favor the reverse reaction.

Identity the stomata components. record your answer under "" slide 2"" on your lab report
Stomata are involved in gas interchange and transpiration. The components of stomata are the pore, the guard cells, subsidiary cells, and the stomatic chamber.
What are stomata?On the leafs' surfaces, there are small pores that regulate gas interchange and transpiration. These openings are the Stomata.
Gas interchange ⇒ CO₂ gets into the plant, and O₂ leaves it Transpiration process ⇒ water expel
Stomata opening and closure depend on water and CO₂ concentration inside the plant.
These pores are surrounded by two kidney-shaped cells called Guard cells. They expand or contract according to the plants' needs, causing the stomata to open or close.
The space left between these guard cells is the pore.
Other cells that vary in shape and number are surrounding the guard cells and are functionally associated with them. These are the subsidiary cells.
The pore is connected to a wide intercellular space inside the leaves called the stomatic chamber.

Be specific about how invasive species impacts the environment here in Hawaii.
What will happen in the future if this issue is not addressed? Why does this issue need to be addressed?
Answer:
Terrestrially, invasive species are proving to be a major difficulty in Hawaii because the islands lack many natural predators of invasive animals. Invasive predators often move to the top of the food chain and disrupt prey populations, particularly small mammals, birds, insects, and plants. Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems.

Answer:
If the energy in glucose was released at once, most of the energy would be lost as light and heat. The light and heat could harm or even destroy the cell.
