what is the effect of telomere caps on cancer cells?
The telomere caps help to maintain genome integrity. In consequence, these repetitive sequences are fundamental to avoid the generation of cancer cells.
Cancer cells are a type of cells that proliferates in an uncontrolled manner, which is generally associated with mutations in the genome capable of altering normal gene expression patterns.
Telomere caps are repeated nucleotide sequences found at the end of chromosomes, which help to maintain genome integrity.
The elimination of these repetitive sequences (telomere caps) due to successive cell divisions triggers chromosomal (genome) instability and thus contributes to the emergence of genomic rearrangements that may lead to carcinogenesis.

Answer:
c
Explanation:

photosynthesis uses carbon dioxide
The best statements could describe the differences between the electron transport chain in cellular respiration and photosynthesis is the electron transport chain in cellular respiration uses oxygen, and the one in photosynthesis does not. Thus, option C is correct.
What is Photosynthesis?Photosynthesis is a biochemical reaction that combines chemicals with biological species to produce energy. Atoms of hydrogen bond with carbon to form glucose.
Carbon dioxide and hydrogen are the reactants that are used from the environment by the plants to make energy. Glucose and oxygen are the products. Splitting water into oxygen gas, hydrogen ions and electrons produces the energy for subsequent electron and proton transport and provides the energy to produce the sugars the plant needs.
The hydrogen atoms from the environment are absorbed by the plants and are combined with the carbon dioxide to yield glucose or sugar molecules for energy.
Therefore, The best statements could describe the differences between the electron transport chain in cellular respiration and photosynthesis is the electron transport chain in cellular respiration uses oxygen, and the one in photosynthesis does not. Thus, option C is correct.

When is the kinetic energy of a pendulum the least?
Question 5 options:
Half the distance on the path traveling back down.
On the path beginning the upwards swing.
At the bottom of the swing.
At the top of the swing where it briefly stops before changing direction.
Answer:
The answer is D. At the top of the swing where it briefly stops before changing direction.
Explanation:
When the pendulum is either at its far right or left position, the bob is at rest and therefore its kinetic energy is equal to zero- making it the lowest point of kinetic energy during the whole process.
Answer:
The answer is C
Explanation:
because when your on the swing the most kinetic energy is where you start to go to the upwards part right when the drop happens
it allows you to swing up very high making the option C correct

List reasons you would or would not be concerned about eating genetically modified food
Answer:
Reasons I would be concerned about eating GMO foods:
Explanation:
The FDA declaring them to be "substantially equivalent" to non-GMO foods amid controversy that adequate scientific testing had not been done.
Michael Taylor being in the FDA when "substantial equivalence" was declared. Michael Taylor was a Monsanto employee before taking the position at the FDA.
The technology itself of taking a gene from one species and inserting it into another species (horizontal breeding). While that may be perfectly harmless it is new technology that many believe has not been proven to be safe.
Greater amounts of pesticides being used on GMO crops, which means more pesticides may be getting in our foods.
Crops that are engineered to produce an insecticide in the plant itself possibly having harmful health effects on us. There is some evidence that this may be happening.

The element lithium has two common isotopes: Li–6 and Li–7 If the average atomic mass of lithium is 6.94004 u, determine its percent isotopic abundances. Step by step and explain.
First we need to determine the average atomic mass of these isotopes.
The atomic masses of Lithium-6 and Lithium-7 are 6.0151amu and 7.0160amu respectively.
Now that we have that, we need to set up the relative abundance problem.
We can do that using the formula (M1)(x) + (M2)(1-x) = M(E)
Because you asked for details, I'll explain what each variable stands for-
M1 = the mass of one isotope
x = the relative abundance
M2 = the mass of the second isotope
M(E) = the atomic mass of the element from the periodic table
Therefor all we do now is plug in our respective variable.
M1 = 6.0151amu (Lithium-6)
x = unknown relative abundance
M2 = 7.0160amu (Lithium-7)
M(E) = 6.94004amu
Now the formula plugged in will look like this:
6.0151x + 7.0160(1-x) = 6.94004
Now doing some quick math, we can determine that x=0.07589
For the last step we need to find the percent abundance of each element, which is quite simple. We take X and multiply it by 100 to find Lithium-6, so 0.076 x 100 = 7.6%
and since then we use 1 - X, so 1 - 0.076 = 0.924
We take that and also multiply it by 100, so 0.924 x 100 = 92.4%
Conclusion:
The abundance of the Lithium-6 isotope is 7.6%, and the abundance of the Lithium-7 isotope is 92.4%.
