Because each daughter cell contains one strand of original DNA, replication is said to be {{c1::semiconservative}}
Answers
Because each daughter cell contains one strand of original DNA, replication is said to be semiconservative. This means that each new DNA molecule formed during replication contains one original strand and one newly synthesized strand.
Why is DNA replication semiconservative in nature?
DNA replication is said to be semiconservative because each daughter cell contains one strand of original DNA and one newly synthesized strand. Here's a step-by-step explanation of the process:
1. The DNA double helix unwinds, separating the two parental strands.
2. Each parental strand serves as a template for the synthesis of a new, complementary strand.
3. Nucleotides pair up with their complementary bases on the template strand (A with T, and C with G) and are joined together to form the new strand.
4. At the end of replication, two daughter molecules are formed, each containing one original parental strand and one newly synthesized strand.
Because each daughter cell contains one strand of original DNA, replication is said to be semiconservative.

does each new cell formed by mitosis have the same or diffent chromosomal material as each ohter
Answers
Mitosis have the same chromosomal material as each other they will contain the same number of chromosomes as their parent nuclei.
Cell division is the driving process of the reproduction at the cellular level. Most of the eukaryotic cells will divide in a manner where the ploidy or the number of chromosomes will remains the same, except in the case of germ cells where the number of chromosomes will be halved.
Mitosis is the phase of the cell cycle where the nucleus of a cell will be divided into two nuclei with an equal amount of genetic material in both the daughter nuclei. It succeeds the G2 phase and is succeeded by the cytoplasmic division after the separation of the nucleus.

Answers
Answer:
Nervous system
Explanation:
The nervous system in humans work together to collect information about the external environment because they consist of the brain, spinal cords and neurons. They collect information from external environment and those information travels through neurons from sense organs like eyes, ears, skin e.t.c as a form of electrical impulses. When they get to the end of the neuron, a chemical called neurotransmitters are released which travels across the cells and send it to the brain, the brain then process it and interprete the signals and respond to it as stimulus.

how much higher is the concentration of minerals in roots than in the soil
Answers
Answer:
hope this helps u bro/broette also a very shiny crown would would be appreciated
Explanation:
The concentration of mineral nutrient elements is higher inside the root-hairs than in the surrounding soil because the absorption of mineral elements from the soil involves active transport by the cells. As the concentration of ions always maintained greater inside the root hair water present in the surrounding soil moves into the roots by osmosis. This dilute solution of water and mineral salts, absorbed from the soil by the roots, can be used for food manufacture in the leaves, only if it can travel up to the highest points of the plant. This upward flow occurs through the xylem.

Explanation:

False. Secondary succession does not happen after primary succession or independently of primary succession.
What is secondary succession?Secondary succession is the process of ecological succession that occurs after a disturbance has disrupted an existing ecosystem, but left some soil and seed sources intact. Unlike primary succession, which starts with bare rock or soil with no living organisms, secondary succession begins in areas where there was already an established community of plants and animals.
Examples of disturbances that can lead to secondary succession include forest fires, landslides, and farming practices that disturb the soil. The process of secondary succession involves the gradual recolonization of the area by plants and animals, with different species replacing one another as the ecosystem gradually returns to a stable state.

When new data is found which goes against an existing scientific prediction, a theory on the subject can either be discarded or modified but scientific laws hardly change because of a new data. The correct option would, therefore, be C.
In science, theories are derived when a phenomenon holds true after several independent investigations have been made into it. When new contradicting data emerge and also holds true in independent findings, relevant theories may either be modified or outrightly discarded for a new one.
Laws, however, are formed from data that holds true for a very wide range of phenomena. Hence, a new contradicting data will not be sufficient to change laws in science.
In summary, changing a current law to account for a new data is NOT a potential result of the research that produced the data.

Answers
IgA (Immunoglobulin A) is the antibody that confers the most important specific local immunity to enteric, respiratory, and genitourinary pathogens.
What is antibody?An antibody is a protein produced by the body's immune system when it detects harmful substances, called antigens. Antibodies recognize and latch onto antigens in order to remove them from the body. They are found in the blood and other bodily fluids and are an important part of the body's defense against infection and disease.
IgA is produced mainly in mucosal areas such as the gastrointestinal tract, respiratory tract, and genitourinary tract, and is the primary antibody found in mucosal secretions. It plays an important role in protecting the body from infections by providing a first line of defense.

the skeletons of mammalian forelimbs represent variations of a structure that was present in their common ancestor. what has most likely caused the variation in forelimbs?
Answers
The variations in forelimbs of the skeletons of mammalian forelimbs are most likely caused by adaptive radiation, genetic drift, mutation, and natural selection.
Explanation:Adaptive radiation Adaptive radiation occurs when a species colonizes a new environment with an array of ecological niches and evolves to exploit these resources. Adaptive radiation can result in a wide variety of organisms being created that are adapted to specific ecological niches, and this can occur in a relatively short amount of time.Genetic drift Genetic drift refers to the random variations in gene frequencies over generations.
It has the potential to cause significant changes in the genetic make-up of a population in a relatively short amount of time, but it is more commonly seen in small populations. Mutation Mutations are random changes in the genetic material of an organism, usually caused by errors in DNA replication. Mutations may be caused by environmental factors such as radiation, or they may be random. Natural selection Natural selection is a mechanism of evolution that occurs when individuals with beneficial adaptations are more likely to survive and reproduce than individuals without these adaptations.

what term refers to the area between the soft palate and the upper portion of the epiglottis?
Answers
The oropharynx is a section of the throat located at the back of the mouth and is involved in both the respiratory and digestive processes.
The oropharynx is positioned directly behind the oral cavity (mouth) and extends from the soft palate, which is the posterior part of the roof of the mouth, to the epiglottis. It serves as a passage for both air and food. During the process of swallowing, the epiglottis folds over the opening of the larynx to prevent food and liquids from entering the windpipe (trachea). This ensures that substances are directed towards the esophagus and into the digestive system rather than the respiratory system.
Additionally, the oropharynx plays a crucial role in vocalization and speech production. It contains the tonsils, which are part of the immune system and help to protect against infections. The oropharynx is also the area where the airway and food pathway cross, making it a vital region for the proper functioning of both systems.
