During DNA replication (S phase), the chromosomes are duplicated, resulting in 16 sister chromatids. During metaphase, the sister chromatids align along the equatorial plane of the cell. During anaphase, the sister chromatids separate and move towards opposite poles of the cell, ensuring that each new cell receives a complete set of 8 chromosomes.

During mitosis, the process by which cells divide, the division of chromosomes occurs in a way that maintains the correct number of chromosomes in each resulting cell. The scenario you mentioned, where one cell with 8 chromosomes divides to form two cells each with 8 chromosomes, is possible due to three key events and their associated cell cycle phases:

DNA Replication (S Phase): Before mitosis begins, the DNA in the cell undergoes replication during the S phase of the cell cycle. This means that each chromosome replicates, resulting in two identical copies called sister chromatids. So, in the initial cell with 8 chromosomes, during S phase, each chromosome is duplicated, resulting in a total of 16 chromatids.

Chromosome Alignment and Separation (Metaphase and Anaphase): During metaphase, the replicated chromosomes align along the equatorial plane of the cell. The sister chromatids are connected at a region called the centromere. In anaphase, the centromeres split, and the sister chromatids separate, becoming individual chromosomes. The spindle fibers pull the separated chromosomes towards opposite poles of the cell.

Cytokinesis: After the chromosomes have separated, cytokinesis occurs, where the cell membrane pinches inward, dividing the cytoplasm into two distinct cells. Each new cell receives a set of chromosomes, resulting in two daughter cells, each with the same number of chromosomes as the original cell (8 chromosomes each).

Overall, through the processes of DNA replication, chromosome alignment and separation, and cytokinesis, the division of chromosomes during mitosis ensures that the resulting daughter cells maintain the correct number of chromosomes.

Answer:

15% is adenine

Explanation:

adenine is paired with thymine meaning the amounts will be equal

DNA is a genetic material, which is made up of purines, pyrimidines, sugar, and phosphate backbone. Chargaff's rules state that the DNA should have a 1:1 ratio of purine and pyrimidines.

The percentage of adenine in the DNA sample is 15%.

In the given example, a DNA molecule is completely made up of thymine. Thymine is a pyrimidine that will form two hydrogen bonds with the Adenine.

Chargaff's rules state that the ratio of purine to pyrimidine is 1:1. In the given sample, 15% of the thymine makes up the DNA, then following Chargaff's rule, adenine percentage will also be 15%.

Thus, the ratio of adenine to thymine will be 1:1.

The acceleration of the car is 2 m/s².

The average velocity of the car is 2 m/s.

The equation acceleration = (final velocity - beginning velocity) / time can be used.

Given:

Initial velocity (u) = 0 m/s (since the car starts from rest)

Final velocity (v) = 20 m/s

Time (t) = 10 s

Using the formula, we can substitute the values:

acceleration = (20 m/s - 0 m/s) / 10 s

acceleration = 20 m/s / 10 s

acceleration = 2 m/s²

Therefore, the acceleration of the car is 2 m/s².

You can use the following equation to determine the average velocity: average velocity = total displacement / total time.

The initial position and the final position are identical since the automobile begins at rest. As a result, the displacement and the ultimate position are equal.

Given:

Displacement = 20 m

Time (t) = 10 s

Using the formula, we can substitute the values:

average velocity = 20 m / 10 s

average velocity = 2 m/s

Therefore, the average velocity of the car is 2 m/s.

Photosynthesis and cellular respiration are two close related and complementary processes. Photosynthesis produces organic molecules and releases oxygen, which are used during cellular respiration to produce water, ATP, and CO₂.

Photosynthesis is a process plant cells go through when absorbing sunlight.

During photosynthesis, light energy and inorganic compounds are used to produce organic compounds -glucose- and release oxygen.

It occurs in chloroplasts and involves two stages: light-dependent and light-independent reactions.

• During light-dependent reactions, oxygen is released, while ATP and NADPH are produced. Both of them are used during light-independent reactions. It occurs in the thylakoid membrane in the electron transporter chain.

• The light-independent reaction occurs in the Calvin cycle in the stroma. During this stage, carbon from CO2 is fixated, and sugar molecules are synthesized

Cellular respiration is the process through which cells use organic compounds to produce energy.

Cellular respiration follows two ways, which depend on the presence or absence of oxygen, and both of them begin with the process of glycolysis, which occurs in the cytoplasm and does not need oxygen to occur.

1. Occurs in the presence of free oxygen.

2. Series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules.

3. Respiration occurs in the mitochondria.

4. Takes place in two steps or stages: Krebs cycle and electron transporter chain.

5. Glycolysis and Krebs cycle produce electrons, which then travel along the electron transporter chain while releasing energy, and ATP is produced.

1. Occurs in the absence of free oxygen

2. Series of reactions by which using pyruvate (product of glycolysis) 2 ATP molecules van be produced.

3. There are two ways in which anaerobic respiration can be produced: lactic fermentation and alcoholic fermentation.

4. Lactic fermentation produces lactic acid and 2 ATP

5. Alcoholic fermentation occurs in two steps, and the final products are ethylic alcohol, 2ATP, and 2 CO₂

6. The whole anaerobic process occurs outside the mitochondria.

Photosynthesis is complementary to cellular respiration.

The sense of smell in tigers is highly developed and serves as a critical tool for survival. It helps them locate prey, establish territories, detect potential threats, and identify reproductive opportunities. The acute sense of smell in tigers enhances their hunting efficiency and contributes to their overall adaptation as top predators in their habitats

The sense of smell in tigers is particularly strong and plays a crucial role in their survival. Tigers have a highly developed olfactory system, equipped with specialized receptors in their nasal cavity that allow them to detect and discriminate various odors in their environment.

The sense of smell is essential for tigers when it comes to finding food. Tigers are carnivores and rely on hunting to sustain themselves. Their acute sense of smell helps them locate potential prey, even from a distance. Tigers can detect the scent of other animals, such as deer or wild boar, which enables them to track and stalk their prey effectively.

The olfactory system of tigers allows them to detect not only the presence of potential prey but also to gather information about the prey's location, health, and even reproductive status. They can identify the scent markings left by other tigers, which help them establish and defend their territories. Additionally, tigers can use their sense of smell to detect the presence of rival tigers or potential threats in their surroundings.

The ability to smell plays a vital role in a tiger's hunting strategy. Tigers often rely on ambushing their prey, and a keen sense of smell allows them to analyze the scent trails left by potential prey, determining their direction and estimating the distance to their target. This helps tigers plan their approach and execute precise and efficient hunting strategies, increasing their chances of a successful kill.

Moreover, a tiger's sense of smell is not only limited to locating prey but also plays a role in identifying potential mates. During the breeding season, female tigers release pheromones that indicate their receptiveness to mating. Male tigers can detect these scents and use them to locate and court females.
