when is the dna of the cells' chromosomes copied? a) after g2 b) at the beginning of mitosis c) during s phase
The DNA of the cells' chromosomes is copied during S phase of the cell cycle.
The full form of DNA is deoxyribonucleic acid. It is a molecule that contains genetic information and instructions for the development and function of living organisms. S-phase or synthesis phase is a stage of interphase, which is the cell cycle's most prolonged phase.
DNA replication occurs in this stage, which means that the cell's DNA is duplicated to prepare for mitosis, which happens during the next stage, the G2 phase.
S phase also ensures that the DNA is correctly copied before being separated during cell division. Chromosome duplication happens in the S-phase of interphase.

question 8 which of the following are likely sources of human dietary phosphorus? a. protein and hydroxyapatite b. protein and aminobisphosphonate c. dna and rna d. phosphoric acid and calcium
The correct option is C : Because they have a phosphate backbone, nucleic acids are sources of phosphorus in food. Nucleic acids include RNA and DNA.
Although "Diets rich in protein and calcium" were suggested as diets that would probably satisfy phosphorus needs, protein and calcium do not contain any phosphorus on their own. Protein-incorporating biological amino acids do not exist.
Many foods naturally contain phosphorus, but dairy, red meat, poultry, shellfish, legumes, and nuts are the largest sources.
These foods contain what is referred to as organic phosphorus. Animal foods absorb it more effectively than plant foods do.
A component of DNA, RNA, bones, and teeth is phosphorus [1]. Phosphorus, in the form of phospholipids, is also a constituent of ATP, the body's primary energy source, and the structure of cell membranes.
The body phosphorylates a large number of proteins and carbohydrates.

What happens to the pressure of a gas if the volume of gas is
increased at a constant temperature?
Answer: If the volume of a gas is increased at a constant temperature, the pressure of the gas decreases.
Explanation:
The relation between variation in volume and variation in pressure of a gas at a constant temperature is given by Boyle's Law which states that: The product of pressure and volume of a mass of a contained gas is constant at a constant temperature.
That is,
Pressure (P) x Volume (V) = constant (k)
[when the temperature (T) is constant; k ≠ 0.]
Or, P = \(\frac{k}{V}\)
That is, pressure varies inversely with volume or an increase in volume at a constant temperature causes a decrease in the pressure of the gas.
Detailed answer:
Gas molecules are always in random motion, and the pressure of a gas is defined as the pressure exerted by these moving gas molecules on the walls of the container as they undergo collisions with the walls of the container. The volume of a gas is defined as the three-dimensional space occupied by all the gas molecules in the container at a particular temperature and pressure. Thus, when the volume increases keeping the temperature constant (thus no change in kinetic energy of the molecules occurs due to temperature), the molecules get more space to move around. Thus the pressure exerted by the molecules on the walls of the container decreases.what happens after we die?
Answer: Our bodies stay fresh for a short period time, then enter rigor mortis, then began the slow process of decomposition.
Explanation:
which of the following is the basis for collision theory? 1. transition state theory 2. field theory 3. molecular orbital theory 4. string theory
The basis for collision theory is the transition state theory, also known as the activated complex theory.
This theory explains how chemical reactions occur by proposing that molecules must collide with sufficient energy and in the correct orientation to form a transition state, which is a high-energy intermediate state between the reactants and the products. The transition state is short-lived and unstable, and can either dissociate back to the reactants or proceed to form the products. Collision theory takes into account the energy of the colliding molecules, the orientation of the colliding molecules, and the activation energy required for the reaction to occur.
what is chemical reactions?
A chemical reaction is a process in which one or more substances, called reactants, are transformed into one or more different substances, called products, through the breaking and forming of chemical bonds. Chemical reactions involve the rearrangement of atoms and the transfer or sharing of electrons. During a chemical reaction, the total mass of the reactants is equal to the total mass of the products, according to the law of conservation of mass.

O F₁ generation only
O P generation only
O F₁ generation and F₂ generation
OP generation and F2 generation
If Mendel had crossed a true breeding dominant plant with a true breeding recessive plant, P generation and F2 generation is the recessive trait visible.
What do you mean by recessive traits?A recessive trait is the weak, unexpressed trait of a dichotomous pair of alleles (dominant-recessive) that has no effect in the phenotype of heterozygous individuals.
Examples of recessive traits are cleft chin, dimples, and freckles are similar examples; individuals with recessive alleles for a cleft chin, dimples, or freckles do not have these traits.
Only individuals with an aa genotype will express a recessive trait; therefore, offspring must receive one recessive allele from each parent to exhibit a recessive trait. One example of a recessive inherited trait is a smooth chin, as opposed to a dominant cleft chin.

photosynthesis is when plants convert sunlight, water and carbon dioxide into energy
photosynthesis is when plants convert sunlight, water and oxygen into energy
photosynthesis is how plants grow
Answer:
Photosynthesis is when plants convert sunlight, water, and oxygen into energy.
photosynthesis is how plants grow
Explanation:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, In most cases, oxygen is also released as a waste product. Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere and supplies most of the energy necessary for life on Earth.

How was it established experimentally that the frequency of recombination (crossing over) between two genes is related to the distance between them along the chromosome?
Crossing over is the exchange of chromosome segments between non-sister chromatids during meiosis. This process is one of the mechanisms responsible for genetic diversity and also serves as the basis for genetic mapping. Genetic mapping is used to determine the position of genes on a chromosome.
To establish experimentally that the frequency of recombination between two genes is related to the distance between them along the chromosome, the following steps must be followed: The frequency of recombinants is determined by cross-breeding parent organisms with different traits. Determining the distance between the two genes is the next step in the process. This is accomplished by observing the percentage of recombinant progeny that result from a particular cross. The distance between the genes is proportional to the frequency of recombinant progeny. Crossing over occurs more frequently between genes that are far apart on the chromosome than those that are close together. As a result, genes that are close together are less likely to cross over and produce recombinant offspring.
To determine the distance between genes on the chromosome, a mapping function is used. By analyzing the frequency of recombinant progeny resulting from different crosses, the distance between the genes can be calculated. This distance is proportional to the frequency of recombinants.

O C. Cracks from tectonic movement when Earth was formed
D. Sediments carried by glaciers and deposited thousands of years

A. Erosion from flowing water over millions of years could explain the formation of a landform such as the Grand Canyon.
The Grand Canyon was formed by the erosion of the Colorado River over millions of years, carving through layers of rock to create the iconic canyon. The river cut through the rock layers due to the force of flowing water, which gradually wore away the softer rock and sediment, leaving behind the harder rock layers that form the canyon walls.
This process of erosion by water is a common mechanism for the formation of many landforms, such as canyons, valleys, and gorges, especially in regions with significant water flow over long periods.

what is the pathway for airflow from the nasal cavity to the location of gas exchange within the lungs?
The pathway for airflow from the nasal cavity to the location of gas exchange within the lungs involves several structures and regions within the respiratory system.
When we inhale, air enters the nasal cavity through the nostrils. The nasal cavity is lined with a specialized tissue called the respiratory epithelium, which contains tiny hair-like structures called cilia and mucus-producing cells. These structures help filter, warm, and humidify the incoming air.
From the nasal cavity, the air passes through the pharynx, which is the shared passage for both air and food. The epiglottis, a flap of cartilage, prevents food from entering the airway by covering the entrance to the trachea during swallowing.
Next, the air moves into the larynx, commonly known as the voice box. The larynx contains the vocal cords and plays a vital role in speech production. It also helps to direct the airflow into the correct pathway.
The air then enters the trachea, also known as the windpipe, which is a tube composed of C-shaped rings of cartilage that provide structural support. The trachea further divides into two main bronchi, known as the left and right primary bronchi, which enter the lungs.
Inside the lungs, the primary bronchi branch into smaller tubes called secondary bronchi. These further divide into even smaller bronchi known as tertiary bronchi. The bronchi progressively become smaller and more numerous, eventually forming a network of bronchioles.
The bronchioles continue to divide into even smaller passages called terminal bronchioles, which finally lead to the respiratory bronchioles. At this point, the respiratory bronchioles transition into the alveolar ducts, which eventually lead to the alveoli.
The alveoli are the site of gas exchange within the lungs. They are small, thin-walled air sacs surrounded by capillaries. Oxygen from the inhaled air diffuses across the thin alveolar walls into the capillaries, where it binds to red blood cells. At the same time, carbon dioxide, a waste product of cellular respiration, diffuses from the capillaries into the alveoli to be exhaled.
In summary, the pathway for airflow from the nasal cavity to the location of gas exchange within the lungs involves the nasal cavity, pharynx, larynx, trachea, primary bronchi, secondary bronchi, tertiary bronchi, bronchioles, terminal bronchioles, respiratory bronchioles, alveolar ducts, and finally, the alveoli where gas exchange takes place.

Sam, Josh, Megan, Danielle, and Isaac are all studying an invasive plant along the Ankh-Morpork river basin and natural areas. This plant, the Venezuelan Salt berry, can grow into a tree up to 10 meters high with a total shade cover many times this height. When one stem is cut, many more will sprout beneath the cut line to produce a tangled web of new branches. The entire tree must be cut at soil level and treated with special herbicides to prevent regrowth. The berries are small, less than 7mm in diameter, and bright red when ripe. They tend to grow in large clusters at the terminal end of branches. Each of our young scientists are testing a different hypothesis to prove how the Venezuelan Salt berry is spreading so quickly along the muddy banks of the river and into the interior. Sam observed that the most abundant species of bird, a common lark, quite enjoys the berries and eats voraciously from the clusters throughout the summer months. Josh observed that when hiking through the wooded areas, there are many areas of bear scat that are red from the abundance of berries. Megan heard people say that bees make a mighty fine honey and local people have been planting them in orchards for their apiaries.
