You read an article on a website that suggests that there may be a new form of cancer-causing mutagen that causes the DNA backbone structure to be disrupted in its normal sequence. Using your knowledge of the structure of the DNA molecule, explain how you might hypothesize such a mutagen might impact the ability for the DNA molecule to do its job effectively.
Answer:
The mutagen might alter the DNA sequence, thereby altering the accessibility to transcription factors and thus activate the expression of oncogenes involved in cell proliferation
Explanation:
The DNA molecule consists of two antiparallel strands of nucleotides that wind around each other. Each DNA strand is formed by a backbone containing sugar (deoxyribose) and phosphate groups. This arrangement allows for DNA replication and transcription (and consequently also protein synthesis) to occur. If a mutagen agent binds to DNA, this might modify its structure, thereby altering DNA replication and transcriptional activity.

Geologists determine absolute age by comparing the amounts of radioactive and nonradioactive elements in rock. The radioactive, or , elements decay into nonradioactive elements. Because this rate of decay is for each element, geologists can compare the amounts of stable and unstable elements to determine how much of the elements have formed over time.
Answer:
1. Igneous. 2. Unstable. 3. Constant. 4. Stable.
Explanation:
Geologists determine absolute age by comparing the amounts of radioactive and nonradioactive elements in igneous rock. The radioactive, or unstable elements decay into nonradioactive elements. Because this rate of decay is constant for each element, geologists can compare the amounts of stable and unstable elements to determine how much of the stable elements have formed over time.
Explanation:
The method used by geologists in calculating the precise or absolute age of a fossil is called radiometric dating. This calculation is done by measuring the amount of energy emitted by some radioactive elements present in the igneous rocks.
Each element with radioactive properties has a constant decay rate of its radiation, which is the amount of radioactivity that it loses over time. After the necessary time, radioactive or unstable elements become stable particles.
Since each element has a constant decay rate, the time that has elapsed since its formation can be estimated.
Although fossils are normally found in sedimentary rock strata -which do not contain radioactive elements- their precise age is calculated using radiometric dating of adjacent igneous rock strata.

Hydrogen - 3 is a radioisotope with a half life of 12.32 years. How long would it take a 40 g sample to decay down 2.5 g ?
Answer:
Whether or not a given isotope is radioactive is a characteristic of that particular isotope. Some isotopes are stable indefinitely, while others are radioactive and decay through a characteristic form of emission. As time passes, less and less of the radioactive isotope will be present, and the level of radioactivity decreases. An interesting and useful aspect of radioactive decay is half-life, which is the amount of time it takes for one-half of a radioactive isotope to decay. The half-life of a specific radioactive isotope is constant; it is unaffected by coTnditions and is independent of the initial amount of that isotope.
Consider the following example. Suppose we have 100.0 g of tritium (a radioactive isotope of hydrogen). It has a half-life of 12.3 y. After 12.3 y, half of the sample will have decayed from hydrogen-3 to helium-3 by emitting a beta particle, so that only 50.0 g of the original tritium remains. After another 12.3 y—making a total of 24.6 y—another half of the remaining tritium will have decayed, leaving 25.0 g of tritium. After another 12.3 y—now a total of 36.9 y—another half of the remaining tritium will have decayed, leaving 12.5 g. This sequence of events is illustrated in Figure 15.1 “Radioactive Decay”.

Hurricanes are generally: ___________.
a. Smaller than mid-latitude cyclones
b. Late summer and early fall storms
c. Areas of strong rainfall and winds
d. Larger than tornadoes
e. All of these
Answer:
The answer is option B "Late summer and early fall storms"
Explanation:
less tropical storms form into Hurricanes. A few great ecological conditions should be available to allow Hurricane. To start with, warm sea waters of in any event 80 degrees Fahrenheit should stretch out to a profundity of 150 feet or more. Warm surface temperatures along are insufficient for typhoon development; there must be a plentiful profundity of warm water to give energy to the tempest. Second, the environment should cool quick enough from the surface upward to permit soggy air to keep on being precarious and convect. Layers of warm air over top stop or "cap" tropical improvement. At long last, there should be minimal vertical breeze shear, that is, change in wind speed, between the surface and the highest point of the lower atmosphere. Solid breezes over top forestall tropical Hurricane development.
Populations of organisms that exhibit a high degree of variation have a greater chance for survival than populations of organisms that show little variation. This statement is
-always true
-usually true
-rarely true
-never true
Answer:
Explanation:
Always trye
Populations of organisms that exhibit a high degree of variation have a greater chance of survival than populations of organisms that show little variation. This statement is usually true. Thus, the correct option will be B.
What is variation in organisms?Variation can be defined as any kind of difference between the different individuals in a species or group of organisms of any type of species. Mutations are the ultimate source of genetic variation, however the mechanisms such as sexual reproduction and the genetic flow can also contribute to mutation as well.
Evolutionary processes are the processes which are based on the selection of variations in a species by environmental variables. These differences may result in higher than usual survival benefits for the individuals as a result of positive trait adoption in an organism, or they may contribute to the genetic drift. Hence, all the variations in an organism have an equal chance of survival.
Therefore, the correct option will be B.

Chemicals used in chemotherapy treatments to fight cancer can also harm cells in hair follicles and bone marrow.
What characteristic do these cels most likely share with cancerous cells?
O They form tumors.
O They spread through the blood.
• They divide rapidly.
O They contain a mutation.
A
Answer:
They divide rapidly
Explanation:
Some normal cells such as hair follicles cells, mouth cells, digestive tract cells, and bone marrow cells divide rapidly. In mammalians, hair follicle cells are cells localized in the skin, specifically in the dermal layer of the skin. In this region, epidermal cells that form the root of the hair divide rapidly by interacting with neuropeptides, hormones, and immune cells. On the other hand, the bone marrow is a spongy tissue found in bones that contain stem cells (which also divide rapidly). In consequence, it is well-known that high-dose chemotherapy treatments may damage these types of cells.

What property of cell membrane allows only certain materials to pass through
Answer:
the answer is selective permeability
