Which BEST describes the process of aerobic cellular respiration?
A: a process of energy cornversion that releases energy from food in the presence of Oxygen, forming new cormpounds
B: a process of energy conversion that captures light energy and transforms it into chemical energy
C: a process of energy trarsfer that converts liquid water into water vapor
Answer:
B.) A process of Energy conversion that captures light energy and transforms it into chemical Energy.
Explanation:
Aerobic respiration is the process of producing cellular energy involving oxygen. Cells break down food in the mitochondria in a long, multistep process that produces roughly 36 ATP. The first step in is glycolysis, the second is the citric acid cycle and the third is the electron transport system.
If a double-stranded segment of DNA has been found to have 23 purines and 15 thymines, how many guanines are there?
Answer: 4 Guanines
Explanation: Following Chargaff's ratio that describes the ration of purines to pyrimidines as 1:1, if there are 23 purines, it follows that there should be 23 pyrimidines; 15 Thymines should therefore be hydrogen bonded to 15 Adenines by complementary base pairing.
We are then left with 8 nucleotides composed of guanines and cytosines in complementary base pairs. This means that half that number (4) should be guanines and the rest cytosines.
The DNA is a double-stranded molecule, which is made up of purine, pyrimidine, a pentose sugar, and phosphate backbone. Chargaff's rule states that any species will have a stoichiometric ratio of 1:1.
The number of guanines in the double-stranded DNA is 4.
In the DNA, the base pairing occurs as:
The guanines bind with cytosine through hydrogen bonding. The adenine binds with thymine with two hydrogen bonds.In the given nucleotide, there are 23 purines (guanine and adenine). There are 15 thymines in the DNA molecule. Based on the Chargaff rule, the 15 thymines will bind to adenine, leaving only 4 guanines and 4 cytosines. Thus, there will be 4 cytosines left to bond with the guanines to achieve Chargaff's ratio of 1:1.
Therefore, the guanine in the nucleotides will be 4.

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.

What property of cell membrane allows only certain materials to pass through
Answer:
the answer is selective permeability
Explanation:
A membrane that has selective permeability allows only substances meeting certain criteria to pass through it unaided. In the case of the cell membrane, only relatively small, nonpolar materials can move through the lipid bilayer (remember, the lipid tails of the membrane are nonpolar).
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.

Explanation:
You can tell the age of a skeleton by looking at:
O1) the length of the femur
O2) the shape of the pelvis
O 3) the number of fused bones
O4) the color of the bones
Answer:
Calculating the age of a skeleton can be done by looking at the number of fused bones (option 3).
Explanation:
The calculation of skeleton bone age takes into account the complete ossification of bones, which occurs at various stages of human development.
In childhood, the epiphyses or ends of long bones are not completely ossified but are formed by cartilage, due to the process of growth. When development is achieved, the growth nuclei and cartilage disappear.
Bone age is a reliable parameter for calculating chronological age, as they are quite approximate.
The other options are not correct because:
1. The length of the femur is useful for calculating height.
2. The shape of the pelvis helps to differentiate the sex.
4. The color of the bones is not a useful parameter to calculate the age of the skeleton.

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”.

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.

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.
