If a DNA strand has 32 % guanine before semi conservative replication occurs, what
percent thymine will each new strand have after replication?
Answer:I believe that the answer would be 18
Explanation:
32 divided by 2 is 18
If a DNA strand has 32% Guanine before semi-conservative replication occurs, then the percent Thymine will each new strand have after replication will be 18%.
The deoxyribonucleic acid (DNA) is a double helix molecule composed of four types of nucleotides: Adenine (A), Thymine (T), Cytosine (C) and Guanine (G).In DNA, Adenine (A) always pairs with Thymine (T), whereas Cytosine (C) always pairs with Guanine (G). The replication of DNA is semi-conservative because after replication each DNA molecule contains one original DNA strand and one newly-synthesized DNA strand.If a DNA molecule contains 32% of Guanine, then the content of G + C is equal to 64%, so the content of T + A is equal to 36% (64 + 36 = 100) and T content is 18% (18 + 18 = 36).In conclusion, if a DNA strand has 32% of Guanine before replication, then the percent of Thymine after replication will be 18%.

What two things of elements organizes elements based on their properties?
The elements are organizes based on their property like metals and non metals and grouping the valence electrons.
When you go down the on the group , the number of electrons increases down group As a result Atomic number also increases therefore the element having higher valence elections are present at the bottom and the the element having low valence electrons are at the top.The elements having large valence electrons have higher size and elements having low valence electron have low size.The periodic table divides into metals , non metals, and metalloids.The metals have ability to lose their electrons to formed the bond with other compound.The non- metal elements share their electrons to form covalent bond with other elements to formed the compound.The metalloid can behave as both metal and non metal.So from above observation we can divides the elements on the basis of metal and non- metal and number of valence electrons.

_____inherited traits that increase an organisms chance of survival, also determine an organism’s niche.
Answer:
Adaptations are inherited traits that increase an organism's chance of survival, also determine an organism’s niche.
Explanation:
Adaptations can be defined as inherited traits that increase an organism's chance of survival and determine its niche. An organism's niche is the place it has in an ecosystem it inhabits - how it lives and survives in it and how it affects it and other species.
Adaptations are a necessary occurrence. As the organism's habitat changes, it has to change as well. In order words, it has to adapt. This process is supported by natural selection - the mechanism that ensures that an advantageous characteristic will become the most common one.
An example of adaptation is what an animal's teeth look like. The shape of an animal's teeth heavily depends on its diet. If it's a herbivore, it will have many molars for chewing grass and plants, and if it's a carnivore, it will have sharp canines to help it tear meat.
bisphosphoglyceric acid (bpg) is a byproduct of glycolysis released into the bloodstream when an animal's supply of oxygen is low. like protons, it decreases hemoglobin's affinity for o2. the effect of high bpg levels would be that:
When an animal's oxygen supply is limited, bisphospoglyceric acid increases the oxygen level by acclamitization.
Acclimatization is the term used to describe the advantageous physiological changes brought on by frequent exposure to a hot climate. Increased sweating effectiveness is one of these physiological modifications. It is converted into a molecule identical to that of 2,3-bisphosphoglyceric acid (2,3BPG). A mechanism called 2,3BPG is employed to control the effective emission of oxygen from haemoglobin. As one of the processes of acclimatization, 1,3-BPG levels will rise in a patient's blood when concentration is low. Low oxygen levels increase 1,3BPG levels, which in turn increase 2,3BPG levels and change how well oxygen separates from hemoglobin.

Ecology, conservation and management of vernal pool ecosystems – proceedings from 1996 is a research paper
What is this research paper about?California has 32 million residents, and that number is still increasing remarkably quickly. Ninety-five percent of the state's wetlands have been lost due to rapid population increase (Dahl, 1990). Vernal pools are one type of wetland that has seen exceptionally severe losses. This study addresses the urgent need to justify the creation of an ecologically sound compensation scheme for vernal pools that will be part of a larger vernal pool conservation strategy. They also talk about how to maintain and restore the functional integrity of vernal pool wetland ecosystems by creating a compensating mitigation plan that is ecologically based. They think vernal pool conservation can be carried out while also improving effectiveness within the current federal, state, and municipal regulatory framework.

How long do carbon stay in plants
Answer:
It depends
Explanation:
Certain plants need certain amounts. Supposedly, it would be thousands of years... but it honestly depends on what plant it is.
From the time of the ancient Romans, through the Middle Ages, and until the late nineteenth century, it was generally accepted that some life forms arose spontaneously from non-living matter. Such "spontaneous generation" appeared to occur primarily in decaying matter. For example, a seventeenth century recipe for the spontaneous production of mice required placing sweaty underwear and wheat in an open-mouthed jar, then waiting for about 21 days, during which time it was alleged that the sweat from the underwear would penetrate the husks of wheat, creating mice.
Experiment #4:
The first serious attack on the idea of spontaneous generation was made in 1668 by Francesco Redi, an Italian physician and poet. At that time, it was widely held that maggots arose spontaneously in rotting meat. Redi believed that maggots developed from eggs laid by flies.
Place yourself in the role of Francesco Redi. Design an experiment that will test this idea. Remember, you are challenging an idea that has been accepted for hundreds of years! You must follow the scientific method closely, account for all variables, and carefully document your procedure to have a chance at disproving this
theory!
#14. state a hypothesis. remember to include the variable you are testing and a prediction of the effects of this variable.
#15. write a step by step procedure for this experiment. include an experimental group and a control group. remember that every variable should be held constant between your two groups except the one your testing. this even includes exposure to air.

Prophase IIMetaphase IIAnaphase IITelophase IIWhat events occur during meiosis I and meiosis II?During meiosis, a specialized type of cell division that occurs in sexually reproducing organisms, two rounds of division take place: meiosis I and meiosis II. Here are the events that occur during each phase:
Meiosis I:
Prophase I: Chromosomes condense and pair up, forming homologous pairs. Crossing over, the exchange of genetic material between homologous chromosomes, occurs. The nuclear envelope begins to break down.
Metaphase I: Homologous chromosome pairs align at the center of the cell, called the metaphase plate, by attaching to spindle fibers.
Anaphase I: Homologous chromosomes separate and move to opposite poles of the cell, pulled by the spindle fibers.
Telophase I: Chromosomes reach the opposite poles, and the nuclear envelope reforms. Cytokinesis, the division of the cytoplasm, may occur, resulting in two haploid cells.
Meiosis II:
Prophase II: Chromosomes condense again, and the nuclear envelope breaks down. Spindle fibers begin to form.
Metaphase II: Chromosomes line up individually along the metaphase plate.
Anaphase II: Sister chromatids separate and move to opposite poles of the cell.
Telophase II: Chromosomes reach the opposite poles, and a new nuclear envelope forms around each set of chromosomes. Cytokinesis occurs, resulting in the formation of four haploid cells.
Overall, meiosis I reduces the chromosome number from diploid (two sets of chromosomes) to haploid (one set of chromosomes), while meiosis II separates sister chromatids to generate four genetically unique haploid cells, known as gametes. These gametes are ready for fertilization and contribute to genetic diversity in sexually reproducing organisms.
