Answer:
Cancer is formed when there are mutations in a number of genes.
Explanation:
Malignant tumors are gene diseases which do not mean that cancer is necessarily an inherited disease (only in 5-10% of cases the cancer is inherited) because the vast majority of other tumors are the result of somatic, ie secondary, mutations that lead to malignant transformation.
Only 2% of human diseases are monogenic (caused by a change in one gene). The remaining 98% of the disease is either polygenic (caused by a change in several genes at the same time) or epigenetic (caused by non-genetic or post-genetic disorders of cellular molecules).
Answer:
Mitochondria- glycolysis
ATP synthase- converts ADP to ATP
Inner membrane- electron transport chain
Matrix- krebs cycle
Explanation:
The mitochondria forms the fundamental site for glycolysis. The glucose is broken down enzymatically to produce carbon dioxide, water and ATP. The krebs cycle is the first stage of aerobic respiration. It takes place in the mitochondrial matrix. ATP synthase is an enzyme that generates ATP during the process of cellular respiration. ATP synthase forms ATP from ADP and an inorganic phosphate (Pi) through oxidative phosphorylation. The mitochondrial inner membrane is the site of the electron transport chain, an important step in aerobic respiration. Energy obtained through the transfer of electrons down the ETC is used to pump protons from the matrix into the intermembrane space, creating an electrochemical proton gradient generating ATP.
Answer:
Why is "sunlight" written above the arrow in the equation, rather than on the either side of it?
Sunlight is neither a raw material nor a product of the reaction, and is the energy source for the reaction.
Answer:
Explanation:
LPG gas is basically propane and butane, and it is odourless in its natural state. The smell that you notice when there is a leak is actually the stench of an entirely different agent, called Ethyl Mercaptan (C2H6S). This substance is added to the gas when it leaves the main storage terminals.
Answer: 1. S = 0.77
2. R = 0.14
Explanation:
1. <u><em>Selection</em></u> <u><em>differential</em></u> is the difference between the population mean and the average of the selected parents. Its symbol is S.
S = mean of selected parents - population mean
S = 6.48 - 5.71
S = 0.77
2. <em><u>Response</u></em> <em><u>to</u></em> <em><u>Selection</u></em> is how much gain you make when crossing over selected parents. Its symbol is R.
R = mean of offspring of selected parents - population mean
R = 5.85 - 5.71
R = 0.14
3. <em><u>Heritability</u></em> is, basically, a statistical variable that shows how much the variation in a trait is due to genetic factors. Its symbol is h².
To calculate it, use Breeder's Equation:
R = h²S
h² = 0.18
4. You would expect the production to be strongly influenced by environment, because heritability lies between 0 and 1. Low heritability means there is low level of resemblance between offspring and parents. As this program heritability is low, the resemblance is small, which means the characteristics are influenced mostly by the enviroment.
